Take someone who walks into the gym who can barely bench press the empty bar, and by the very next workout they may be able to add 5 or 10-pound plates to each side. Soon those plates become 25-pounders, then 35, then 45, and then…then it starts getting complicated. The problem is that making continuous strength gains becomes not just addictive, but expected. A typical scenario is that a beginner starts with the lightest weights available, and each week sees a linear progression in strength. Sometimes a new lifter can make some type of progress, either in more weight lifted or another repetition performed, just about every workout for months. This gets them thinking thoughts such as, “I went from a 110-pound bench press in January to 170 in March, so if I keep adding five pounds a week, by the end of the year I should be pushing 350!” Yes, during the first several months of training tremendous progress can be made – and certainly there are some men who have bench pressed 350 pounds after a single year of training. But such individuals are the exception, not the rule. As you get stronger, you eventually hit a point of diminishing returns, such that it takes considerably longer to be able to slap on those additional 2 ½-pound plates. Periods of stagnation are to be expected, and could take 5 years, 10 years, or even longer before an individual finally reaches their maximal physical potential. Another factor that must be taken into consideration in looking at the initial progress of beginners is that much of the apparent strength improvement that takes place is not from an increase in muscle size. Rather, these improvements are more due to neurological changes, such as learning how to more efficiency contract the muscles and also how to perform the exercise with better technique so more weight can be lifted. As an individual progresses in weight training, it becomes more important to experiment with training methods other than straight linear progressions. Before getting into the details of these methods, it’s important to have a basic understanding of the characteristics of muscles. There are two basic fiber types, type I and II, and they are each broken into subcategories. The type I fibers are called slow-twitch fibers and they produce low amounts of strength and power but are very fatigue resistant. Endurance running or swimming will favor type I muscle fibers. The type II fibers are called fast-twitch fibers and they produce high amounts of strength and power, making you fast and explosive. They fatigue quickly. Within the two fiber types there are at least seven subtypes but, for now, all you need to be aware of is the distinction between type I and II. It’s also important to consider that each muscle has a unique distribution of muscle fiber types. For example, the calf consists primarily of two muscles, the two-head gastrocnemius and the one located under it called the soleus. The gastrocnemius contains predominantly fast-twitch fibers and the soleus contains predominantly slow-twitch fibers. This difference requires that each of these muscles be trained to best develop their primary fiber type. Understanding the different types of muscle fibers is the first step to learning how to design strength and conditioning programs. The next step is to take a closer look at the various types of strength. Poliquin International Certification Program- Level 1 Manual © 1982-2016, Poliquin Group 2 Chapter 1: Classification of Strength Qualities Strength can be classified into many different types, each defined by differing capabilities of the neuromuscular system and the time frames of strength expression. Here are the four major types of strength that can be used as a starting point for designing resistance training programs. Hypertrophy Hypertrophy is the growth of muscle; the existing muscle fibers respond to strength training by growing larger. Mechanical loading, or weightlifting, triggers processes within the cells and muscle fibers that lead to protein synthesis and muscle growth. This type of training targets the Type IIa muscle fibers. An individual muscle fiber is made up of two components called a sarcoplasm and a sarcomere. Growing the sarcoplasm, or sarcoplamic hypertrophy, involves the increase in non-contractile proteins and fluids between muscle fibers so that the cross-sectional area of the muscle is larger, but the density of muscle fibers decreases. Sarcoplasmic hypertrophy won’t increase muscle strength and is a technique used by bodybuilders because it makes their physiques more imposing. One of the key factors affecting hypertrophy is the length of the muscle bellies. For example, the lower a biceps muscle inserts (i.e., the closer to the elbow joint), the greater that muscle’s potential for hypertrophy. Another factor is the hormonal makeup of the individual. Regardless of genetic limitations, however, a significant amount of muscle can be achieved with hard training. Functional Hypertrophy Functional hypertrophy, which primarily involves the Type IIx fibers, develops the muscles in such a way as to improve physical performance. Growing the sarcomere, or sarcomere hypertrophy, is the increase in the size and number of sarcomeres in the myofibrils, which make up an individual muscle fiber. Sarcomere hypertrophy increases the density of myofibrils that contract to make a muscle motion. This hypertrophy leads to greater strength. Sarcomere hypertrophy is what we are referring to when we talk about functional hypertrophy. For a sprinter, functional hypertrophy will involve training that is both heavy and fast to help the sprinter become more explosive and faster without inducing too much gain in total body weight. In comparison, a football defensive lineman needs to be explosive and fast, but they also need to weigh a lot since they have 3 to block and push players who can weigh around 300 pounds. A lineman who is very strong who only weighs 180 pounds will get squashed by a 300 pounder even if the 180-pounder is stronger. The definition of functional hypertrophy for non-athletes is the same as for athletes—it grows your muscles in a way that will improve physical performance. In addition to improving body composition and supporting metabolism, functional hypertrophy can help people deal with chronic pain and help prevent injury. It all has to do with which muscle fibers you grow with your training. Stronger type II fibers have been shown to decrease the risk of falls and fractures in older individuals. On the flipside, type II muscle fibers are more susceptible to loss of strength and size as we age, which produces a proportionately larger loss in power and strength. This puts us at greater risk of falls, injuries, and poor physical performance. Relative Strength Relative strength, which involves the Type IIb fibers, is the maximum force an individual can generate per unit of bodyweight, irrespective of the time of force development. High relative strength is of critical importance in sports that involve jumping, such as volleyball and gymnastics, and in sports that have weight classes, such as judo, wrestling, and boxing. This brings up the concept of intensity. Intensity is defined by how much weight is on the barbell, with 100 percent intensity being the maximum amount of weight used for 1 repetition. The more weight lifted, the higher the level of muscle tension achieved. Although performing sets of 12-15 reps in squats is quite challenging, using heavier weights for lower reps has a higher intensity level. The number of reps performed is closely related to the weight used. In the sport of weightlifting, three or more reps are associated with an increase in muscle mass, and singles and doubles are associated more with maximal and relative strength. You’ll often find that when a specific intensity is prescribed for a weightlifter, it is associated with a repetition range. For example: 1-2 reps, 95-100 percent; 3 reps, 90 percent; 4-5 reps, 80-85 percent. Poliquin International Certification Program- Level 1 Manual © 1982-2016, Poliquin Group 4 One method of developing more powerful athletics without increasing their bodyweight is plyometrics. Plyometrics are any activity that involves a rapid stretching of a muscle (eccentric phase) immediately followed by a rapid shortening of that muscle (concentric phase). Stepping off a low platform and immediately rebounding upward upon landing is considered an example of a plyometric exercise; however, the delay between the phases needs to be short, no longer than .25 seconds to use the energy stored during the eccentric phase. To achieve this effect, plyometrics requires a mechanical shock stimulation that stimulates the muscles to produce the highest levels of muscle tension as rapidly as possible. The dynamic nature of shock training creates two processes: 1) a reflex increase in muscle tension and 2) the release of elastic energy stored in the muscles and tendons. Plyometrics do little to make an athlete stronger, but rather enables them to demonstrate strength faster. Strength Endurance Strength endurance, which involves the Type I fibers, is the capacity of a muscle to maintain consistent force output at a percentage of maximal strength greater than 30 percent. In other words, strength endurance is characterized by high strength levels coupled with high levels of endurance. Athletes who want to improve strength endurance should consider the benefits of weight training. Although many runners don’t see the value in lifting weights, running speed is influenced by being able to apply more force into the ground, not by moving the arms and legs faster. Also, stronger muscles do not have to expend as much energy to produce force as weaker muscles. Poliquin International Certification Program- Level 1 Manual © 1982-2016, Poliquin Group 5 Poliquin International Certification Program- Level 1 Manual © 1982-2016, Poliquin Group 6 Chapter 2: Characteristics of Effective Training Throughout this course you will be provided with workouts that apply the principles discussed in the text. These workouts use a specific formula that allows for precise control over all loading parameters of program design. The Workout Formula Tempo These workouts use a four-digit system to represent how long it takes to complete the different phases of strength training repetition. Let’s start with the speed at which exercises are performed, or tempo. Tempo is broken down in the following manner: The first number is the eccentric lowering, that is, when you lower the resistance (e.g., going down in the squat or bringing the bar to your chest in the bench press). In other words, when the muscle is being placed under stretch and the muscle is lengthening. The second number is the time of pause in the stretched position. The pause is usually between the eccentric (lowering) phase and the concentric (lifting), phase (e.g., the bottom position in the squat or when the bar makes contact with the chest in the bench press). S o the “2” in a 4210 tempo in the bench press would refer to a 2-second pause when the bar makes contact with the chest. It can also refer to a pause taken during the middle of a concentric range. A 5310 tempo in the reverse curl would indicate a 3-second pause at a predetermined angle in the concentric range of the reverse curl. 7 The third number is the concentric contraction, that is, lifting the weight (e.g., rising in the squat or pressing the bar to arms length in the bench press. In this case, the muscle is shortening. If an X is present in the tempo expression instead of a number, it implies explosive action with full acceleration. The fourth number is the time of pause in the contracted position (e.g., the top of a curl or chin-up). Thus, 2010 in the flat dumbbell press would mean 2 seconds to lower dumbbells, no pause (0), lifting for a count of 1, and no pause at the top. As another example, in the case of 4211 in the chin-up, it would mean 4 seconds to lower yourself to the arms outstretched position, a 2-second pause in the stretched position, raising yourself for a count of 1, and pausing for 1 second at the top. Throughout this manual you will see many examples of training programs. These programs will be written in the same format you will see throughout your PICP experience: A1. Bench Press 5 6-8 4010 90 sec Respectively, the format is as follows: exercise number, exercise, sets, reps, tempo and rest. We will review the important components of these loading parameters. Excerise Number The exercise number tells you the order in which to perform the exercises. It will always be a letter that may be followed by a number. For example, A1 and A2 are the A Series exercises. There is no limit to the number of exercises per series, which may vary with the training method you are using. Example 1. You would perform a set of the A1 exercise. Then you will rest 90 seconds, then perform a set of the A2 exercise. At the end A2 you will rest 90 seconds and go back to A1. You will complete the exercises like this until you complete 5 sets. A1. Incline Barbell Bench Press A2. Bent-over Row 5 5 6-8 6-8 4010 90 sec 3020 90 sec After the fifth set you would alternate between B1 and B2 exercises. B1. Flat Dumbbell Press B2.

Flat Dumbbell Press B2. Seated Row 5 4 4 4-6 4010 180 sec 8-10 3010 75 sec 8-10 3010 75 sec Poliquin International Certification Program- Level 1 Manual © 1982-2016, Poliquin Group 8 Reps There are different rep schemes you can use when writing programs. The most common are straight reps, 3-rep window, wave loading and drop sets. Straight reps are characterized by a single number. You will perform the exact number of reps for the sets. A. Incline Barbell Bench Press 5 6 4010 180 sec Here the 3-rep window is written as a range. When you are lifting your target is to reach the upper-end repetition number or at least reach the lower-end repetition number. A. Incline Barbell Bench Press 5 4-6 4010 180 sec The next type of rep scheme is not only used with wave loading, but you will see it when using ascending sets, descending sets and progressive sets. You will perform the number of reps respectively with each set. It is typified by using a comma to separate the reps per set. From the example below, in Set 1 you will perform 2 reps, Set 2: 4 reps, Set 3: 6 reps, Set 4: 6 reps, Set 5: 4 reps, Set 6: 2 reps. A. Incline Barbell Bench Press 6 2,4,6,6,4,2 4010 180 sec Unlike a wave loading scheme where each number represents a set, drop set reps are performed all within the same set. It is typified by a forward slash. From the example below, in Set 1 you would perform 10 reps, take a minimal rest to decrease the load (weight), perform 8 reps, take a minimal rest to decrease the load, then perform 6 reps. You would repeat that same format until you complete all 5 sets this way. A. Incline Barbell Bench Press 5 10/8/6 4010 180 sec Tempo One of the ways we determine the time under tension (TUT) of an exercise or a workout is through the 4-digit tempo prescription. In the example below using the incline bench press, you would lower the weight to your chest in 4 seconds. When you get into the bottom position you will not pause and immediately starting lifting the weight in 1 second. You will not pause at the top and go right into your next repetition. A. Incline Barbell Bench Press 5 4-6 4010 180 sec With that background, let’s look at some of the characteristics of effective program design. Poliquin International Certification Program- Level 1 Manual © 1982-2016, Poliquin Group 9 Progressive Resistance During the course of a proper strength training program, muscles adapt to the stress of lifting by becoming stronger. To be effective, the stress placed on muscles must represent an “overload,” that is, a load greater than the one used in the previous activity. Let’s use another analogy: If you went from a sedentary desk job to working as a lumberjack, your body would undergo some interesting adaptations as it struggled to cope with the unfamiliar environmental stressors inherent in that profession. You would most certainly develop calluses on your hands as a result of grasping axes, saws and other implements for hours each day. These calluses, however, would be exactly the same size one year after getting your new job, three years after, six years after, ad infinitum. Why? Because the stress to your hands never increased over that period of time. If an individual can bench press 100 pounds, performing workouts that used only 50 pounds would not provide the appropriate load to create a strength training effect. To create an overload, you will need to increase your weights throughout each workout. Strength training is no different. If an individual can bench press 100 pounds, performing workouts that used only 50 pounds would not provide the appropriate load to create a strength training effect. One of the factors to assess if you are effective writing training programs is if your client is constantly progressing. During a proper strength training program, muscles adapt to the stress of lifting by becoming stronger. To be effective, the stress placed on muscles must represent an “overload,” that is, a load greater than the one used in previous activity. One overload concept that can be used is the 2% Rule in untrained athletes and 1% Rule in trained athletes using heavy weights. This rule is that each workout you will want to increase your load by at least 2% Another way to ensure you are progressing your programs properly is alternate between accumulation and intensification phases. In accumulation phases, your primary stressor is volume and you are looking for a muscular adaptation. Volume is determined by the amount of work you do in a program and the number of sets you perform. In accumulation, you will use hypertrophy and strength endurance training methods. After you complete an accumulation phase, you will go into an intensification phase, where the main stressor is intensity and you are looking for a neuromuscular adaptation. Intensity is defined by how close you are working to your 1RM. Recovery Recovery is an important and usually overlooked aspect of training needed to reach goals. Recovery in the short term is determined by your rest intervals and is determined long term by your training frequency. Muscles adapt and become stronger during rest periods, not during exercise. This adaptation phase is referred to as overcompensation. Muscles must therefore be given time to recover from training. Depending on the Poliquin International Certification Program- Level 1 Manual © 1982-2016, Poliquin Group 10 training intensity and on the athlete, 48 to 96 hours of recovery are necessary for tissue repair and protein synthesis. If the training stimuli are too far apart, the overcompensation will fade away and strength levels will eventually return to previous levels. If training stimuli are too close, overcompensation will not be allowed to happen and a drop in strength can result. Similarly, if maximal-intensity stimuli are overemphasized, a state of general exhaustion may occur. All stressors have similar general/nonspecific effects on the body. For example, a strength training session will trigger specific adaptations in your body (larger and stronger muscle fibers in the first instance, and an increase of white blood cells in the second case). Both stressors will also generate a general, nonspecific response from your body through various neural, hormonal and other biochemical means. If several stressors are imposed, the total general effect may be too large for your body to resist, and exhaustion may occur. Variety Beginners may be able to show improvement for several months on a fixed weight training program. However, as athletes become stronger, variety must become an essential component of training to elicit a maximal training response over time. In contrast to most machines that offer only a few variations in performance, barbell exercises can accommodate endless variations of execution. For example, squats can be performed with the barbell on the back or on the collarbone, with the feet in a narrow or wide stance, or performed at a different angle on a hack squat machine; the starting position of an exercise can be changed as well. Paradoxically, specificity must be balanced against variability in training programs for the following reasons: 1. The effectiveness of any program is a function of the degree that it challenges your body. The problem is that familiar programs are less challenging because your body has had time to figure them out. Consequently, every time you repeat a training program, it becomes less effective. 2. All programs have both negative and positive features, no matter how well designed or specific they are. If you spend too much time on one program, you tend to adapt to the positive aspects and accumulate the negative ones. 3. Unchanging training routines lead to overuse injuries. According to Dr. Sal Arria, Sports Medicine Director for the International Sports Sciences Association, “Adopting long-term training habits of any kind is very often a precursor to degenerative changes in the joints – advanced athletes are particularly vulnerable since their training tends to become more and more specific over time.” For these three reasons, it’s crucial to regularly (every 2-4 weeks) change acute program variables. These variables include frequency, exercise selection, number of exercises, order of exercises, length of training session, number of repetitions, number of sets, length of rest periods, and the speed of muscle contraction during an exercise. Poliquin International Certification Program- Level 1 Manual © 1982-2016, Poliquin Group 11 The following workouts demonstrate the aggressive advancement of the reps, tempos, and exercise selection for a beginner and advanced athlete. Beginner Athlete Phase 1 This program uses rep-range windows. Because beginners have poor intra/intermuscular coordination, their weight selections will vary greatly from one set to the next. In the following workout example, intensity of the resistance decreases from one exercise series to the next. This prevents the client’s nervous system from fatiguing while maintaining same intensity across the different exercise series. A1. Seated DB Hammer Curl A2. Decline DB Triceps Extension B1. 45 degree Incline Supinating DB Curl B2.

The client’s nervous system efficiency might still not be optimal, so descending sets are used to prime the nervous system. The intensity still decreases from one exercise series to the next, but to a lesser degree than in Phase 1. A1. EZ Bar Reverse Grip Curl 5 6,6,6,4,4 5010 90 sec A2.

Rope Handle Cable Pressdown 4 6-8 4010 75 sec Advanced Athlete Phase 1 As a client advances in training age, they can progress to a loading pattern with a narrower rep-range across the reps selected. This loading pattern provides a more concentrated effort to the muscles trained. A1. Barbell Curl Narrow Grip 5 6, 6, 8, 8, 8 4011 75 sec A2. Parallel Bar Dip 5 6, 6, 8, 8, 8 2210 75 sec B1. Seated Zottman Curl 4 8-10 3110 60 sec B2. Incline DB Triceps Extension 4 8-10 3110 60 sec Advanced Athlete Phase 2 With an advanced training age, you can program more advanced and intensive training techniques into a client’s training programs. To continue making progress, advanced trainees require the use of loading patterns that prime the nervous system, improving its efficiency. The first three sets of this program are performed with a broad pyramid to improve the athlete’s nervous system efficiency, allowing greater resistance to be used in the latter three sets of the broad pyramid. Partial range of motion allows for greater overload on the muscles trained, stressing the muscles with a resistance greater than that utilized with regular range of motion exercises.

It follows that strength training must be specific to transfer to athletic performance. Thomas Kurz said it well: “No matter how much mass and strength one gains from performing general strength exercises, if the neuromuscular patterns of these exercises are not resembling those of the competitive technique, little or no strength gain will show in specialized technical tests or in competition.” As such, a strength training program should be specific along the following parameters: Movement Pattern. The muscles most used in a sport should get priority during workouts and be developed in the work angles, planes and directions of the movements encountered in sports. For example, cable pulling Poliquin International Certification Program- Level 1 Manual © 1982-2016, Poliquin Group 13 exercises such as wood chops can imitate the various movements that occur in a golf swing. Movement Speed. Many sports techniques are of an explosive type while others are of a static nature. In judo, throws would be considered explosive movements and hold-downs would be considered static. This is why many strength training programs often require quick lifts to imitate powerful actions and slower types of lifts imitating the slower moves seen in some techniques. Muscle Contraction Type. The training exercises should reflect the contraction type involved in the sport. Often, all three types of contraction exist in a sport and as such should be emphasized in varying degrees. For example, in judo isometric training will help hold-downs and chokes, and concentric and eccentric occur in throws. Contraction Force. Various degrees of muscle force are necessary in sports, depending on the action being performed. In tennis, a high degree of muscle force is needed during a serve, but in net play less force is needed to ensure precise ball placement. Poliquin International Certification Program- Level 1 Manual © 1982-2016, Poliquin Group 14 Part 2 Manipulating Loading Parameters Loading parameters include reps, sets, rest intervals, tempo, exercise selection, number of exercises, rate of exercise change, exercise order, and exercise frequency. This section will look at the first four of these. Chapter 3: Repetitions Chapter 4: Sets Chapter 5: Rest Intervals Chapter 6: Tempo Chapter 3: Repetitions The first step in designing workout programs is to decide how many reps to perform. The selection of reps influences all other components of a workout, such as sets, tempo, rest intervals and even exercise selection. The amount of resistance used for a specific exercise is probably the single most important variable in strength training. How much weight (load) is lifted determines how much tension is imposed upon a muscle, and how much tension is imposed upon a muscle determines the strength training response. The intensity of an exercise can be described in terms of repetitions maximum (RM). For example, the maximum weight that can be correctly lifted four consecutive times without significant rest would be known as the 4RM. The relationship between reps and repetition maximum is known as the 1RM continuum. Although the number of reps an athlete performs influences the training effect, it’s also important to consider the speed at which these reps are performed. Unfortunately, in the strength training literature most researchers have failed to take into consideration the effects of different repetition speeds, assuming that all reps are performed at roughly the same tempo. The number of repetitions you select will fall on what’s called a neuromuscular axis. This theory states that for a given tempo of execution, lower repetitions emphasize neural adaptation and higher repetitions emphasize muscular adaptation. The scientific basis for this premise has been proven time and again: Groups training with low repetitions achieved greater gains in maximal strength; groups training with high repetitions achieved greater gains in strength-endurance. Because the number of repetitions performed influences how much an individual can lift, this section will review the basic principles for selecting reps. Many of these principles overlap. The Number of Reps Dictates the Load Although percentages are a useful tool in Olympic-style weightlifting, it’s difficult to use percentages for most weight training exercises because of the variety of muscle types in each muscle. For example, the two major muscles of the calf are the gastrocnemius (upper calf) and the soleus (lower calf). Although the exact numbers vary, the gastrocnemius primarily contains fast twitch fibers and the soleus primarily contains slow twitch fibers. Fast twitch fibers respond better to low reps and heavy weight, which produce the highest levels of muscle tension, whereas slow twitch fibers respond better to higher reps and thus relatively lighter weights but longer exposure to muscle tension. 16 Given all the variables that can influence your performance on a given day, including the time of day you lift or how much sleep you got the night before, it’s nearly impossible for a coach to predict the exact weights you can use in a given exercise. Percentage systems frequently lock athletes into specific weights, regardless of what they’re capable of lifting that day. If somebody isn’t having a good training day, the weight would be too heavy, and on a good training day it’s too light. Furthermore, many athletes get frustrated trying to follow precise percentage-based workouts and thereby increase their risk of injury. If you’re told to perform 90 percent of your best squat for 3 sets of 2 reps and you miss both reps on the first set, trying that same weight for the remaining sets could subject yourself to a greater risk of injury as your technique becomes compromised. It’s also important to consider that neurological efficiency changes with training age: as athletes get stronger, they need to shift toward using weights that are closer to their one-rep maxes. As a result, it’s usually better to determine the repetition bracket you want an individual to perform and then let the repetitions determine how much weight they should use. Variables that Influence Rep Selection There is no magic number when it comes to rep selection. Repetition protocols must change depending on factors such as the condition of the athlete, the nature of the exercise and the goal. The following are some general principles to consider about rep selection. Training Goal When writing workouts, first determine the desired training effect and then select a repetition bracket that suits that goal. If you’re writing a program to maximize muscle mass, select a load that enables the client to complete between 6 and 12 reps. If an individual can perform only 5 reps with the weight, the weight is too heavy; if he or she can perform 13 reps, the weight is too light. With each strength quality there are specific rep ranges to achieve that training effect. Strength Quality Reps Intensity Relative Strength1-5 85 % + Functional Hypertrophy 6-8 79 -84 % Hypertrophy9-12 70-78 % Strength Endurance13 + 30-69 % One thing to note about these loading parameters is that it is a continuum, and the intensity percentages and the rep ranges are approximate. Depending on the fiber type, of a muscle these ranges will vary. The following workouts are designed to achieve a specific goal in terms of strength quality: Relative Strength With lower reps, more sets need to be performed to generate the sufficient time under tension (TUT) required to produce the desired training effect.

There is an optimal number of reps per muscle group for each individual, and this is strongly influenced by the fiber makeup of the muscles. Those gifted with a large number of fast-twitch motor units always do fewer reps at a given percentage of maximum. Thus, while the average trainee does about 7RM at 80 percent of his or her maximum, a high fasttwitch individual may complete only 3 reps at this percentage. Conversely, high slow-twitch individuals who are highly trained aerobically have been shown to do 12RM to 37RM at 95 percent of maximum, in contrast Poliquin International Certification Program- Level 1 Manual © 1982-2016, Poliquin Group 18 to the average person’s ability to do only 2RM to 3RM at this percentage. There is substantial empirical evidence and scientific research to suggest that the development of maximal strength is best accomplished by using loads representing 70 to 100 percent of maximum. Therefore, it’s essential to determine the exact number of repetitions to be performed at this percentage range. For most fast-twitch individuals the optimal rep bracket for strength gains falls within the 1-to-6-rep range while most individuals will make gains in the 1-to-12- rep range. In both of these examples they are working at 70 to 100 percent of maximum. Furthermore, the fast-twitch athletes would normally use more sets and often respond better to short rest intervals, 1-3 seconds, between reps. Poliquin International Certification Program- Level 1 Manual © 1982-2016, Poliquin Group 19 Here are examples of two workouts that focus on specific fiber types: Fast Twitch Fiber Dominance – Seeking Relative Strength Fast twitch fiber dominant clients should predominately train with intensities favoring their muscle fiber dominance.

Analysis of the training of elite weightlifters reveals that the snatch is rarely performed for more than 2 reps per set. In the case of the power clean, when performing more than 6 repetitions the small muscles such as the rhomboids (an upper back muscle) would tire out first, causing a change in exercise posture. This fatigue would lead to improper technique, impaired motor learning, and perhaps a greater risk of injury. The same goes for front squats, where the postural muscles will tire out isometrically before the prime movers if the time under tension is too long. This is why knowledgeable strength coaches rarely prescribe more than 6 reps per set for the front squat and even fewer for the power clean. Here is a workout that adheres to these training ideas: Poliquin International Certification Program- Level 1 Manual © 1982-2016, Poliquin Group 20 A. Push Press B1. Flat Biacromial Bench Press B2.

Moreover, even though the following conclusion has yet to be validated by science, there are specific repetition ranges that are more appropriate for certain muscle functions. For example, training the knee flexors with sets of 12 repetitions appears to have little bearing on hypertrophy gains. Conversely, when training the knee extensors, sets of up to 50 repetitions can induce hypertrophy. The reason for this appears to be that knee flexors are used mainly for explosive tasks, while the knee extensors are used in maintaining posture against gravity and are also used for repeated stretch-shortening tasks such as rowing. Optimal rep ranges for different muscle fibers are as follows: Slow Twitch Type I Fibers Mixed Type IIa Fibers Fast Twitch Type IIb Fibers 12+ reps 6-12 reps 1-5 reps Here’s is a list of body parts and the primary muscle fiber composition: Poliquin International Certification Program- Level 1 Manual © 1982-2016, Poliquin Group 21 Poliquin International Certification Program- Level 1 Manual © 1982-2016, Poliquin Group 22 Muscle Fiber Type It’s not only the muscle fiber type that will dictate the reps, but it also includes the type of muscle fiber in your client. The fiber composition of any given muscle influences the number of reps required to achieve a training effect. There is an optimal number of reps per muscle group for each individual, and this is strongly influenced by the fiber makeup of the muscles. In the upper body structural balance assessment section you will learn how to test your athlete’s muscle fiber type. Although you are only testing the upper body muscles, there is crossover to the rest of the body. Here are examples of two workouts designed to focus on specific fiber types: Fast Twitch Fiber Dominance – Seeking Relative Strength Fast twitch fiber dominant clients should predominately train with intensities favoring their muscle fiber dominance.

Eccentric work is best accomplished with sets of 1 to 6 repetitions since supra-maximal loads are used in this method. Depending on the muscle group or exercise used, loads as high at 175 percent of maximum for controlled eccentric repetitions have been used successfully. Using an isometric contraction will minimize the use of elastic energy and recruit additional muscle fibers. You can use an isometric pause at the bottom position (after lowering the weight) and at the top position (before lowering the weight). It is best to use sets of 5-10 repetitions.

Some exercises are explosive, have a large range of motion and involve multiple muscle groups. Other exercises have a short range of movement and involve smaller muscle groups. Individual Differences Coaches often make the incorrect assumption that training equals results without factoring in the uniqueness of the individual. The training program should be “fitted” to the individual, rather than vice versa. As previously mentioned, an example of an individual difference is the fiber type of the athlete. One athlete may respond better to a certain rep range compared to another. Continuing, some athletes may respond better to rep and set changes more frequently (every 1-2 weeks), while others may respond better to less frequent changes (every 3-4 weeks). Many factors influence the rate of adaptation to training are genetic, including muscle fiber makeup, systemic recovery rate, and hormonal response. As a coach, you will want to pay attention and track your athlete’s progress to effectively progressively improve your client. Poliquin International Certification Program- Level 1 Manual © 1982-2016, Poliquin Group 24 Training Age Training age refers to the number of years an individual has been participating in serious strength training. If an individual has been strength training seriously for one year, that represents a training age of one; if it’s two years that equals a training age of two, and so on. The average newcomer to weight training can often perform a 20RM at 75 percent of maximum. After one year of training he or she may be down to 10RM for the same percentage, and after 5 years the same athlete may barely be able to perform 4RM. Also, there are differences in the 1RM between sexes, as well as differences between individuals. Let’s look at three relative strength workouts for athletes with different levels of training experience. Relative Strength – 1 Year Training Age A stand-alone exercise, rather than a superset, is trained with the highest intensities to prevent overwhelming the nervous system with two exercises. A stand-alone exercise allows the client to focus their mental efforts and energy substrates on a single exercise. A. Seated BB Press B1. Decline DB Press B2.

This means strength increases conform to a “dose-response” that is correlated to the number of sets prescribed. Usually 1 or 2 sets are enough for beginners as a training stimulus, but after 6-12 workout sessions the coach must increase an athlete’s volume of training because the muscles will have adapted. If the volume is not increased, progress will slow down and then plateau for extended periods. The first 30 percent of strength gains come from improvements in intermuscular coordination. In effect, athletes “learn” to lift so that they become more efficient by being able to turn on the systems that are needed and to turn off those that are not. This learning curve explains why a novice lifter will often have a very erratic bar path during his or her first attempt at the bench press, even though it is a relatively simple motor task. Once initial strength fitness is achieved, a multiple presentation of the stimulus (3-6 sets) with specific rest periods between sets is superior to a single presentation of the stimulus. However, it’s important that this increase is performed progressively. When an athlete has completed several years of proper training, it may be necessary to prescribe 10-12 sets of a single key exercise that is highly correlated to performance in that athlete’s sport. For example, international success in the luge and the hammer throw are highly correlated to maximal strength performance in the pull-up, and in judo to grip strength. 27 Relationship Between Reps and Sets There is a minimum threshold of work that must be performed for optimal size and strength gains. Many former Eastern Bloc and Western strength training authorities and weightlifting coaches have suggested that there is an inverse relationship between the number of sets and the number of reps. In other words, when using low reps, do a high number of sets; when using high reps, do a low number of sets. The rule to remember is that the higher the neural training effect desired, the more sets (for example, 5 or more) are needed. When training with low repetitions (1-5), most of the adaptations occur in the nervous system, hence this intensity zone is described by the Germans as “intramuscular coordination training.” Regarding practical application, the fewer reps an athlete performs per set, the more sets he or she needs to achieve the appropriate training response. The rationale is that there is a minimal optimal volume for strength development and that when training with low reps, a higher number of sets would ensure sufficient time of loading. More recently, a mathematical model establishing the inverse relationship has been proposed. Training with high loads is like learning a foreign language: Multiple presentations of the learning stimulus must be present to assure modification and retention of the acquired learning process. Conversely, when a coach is seeking morphological or biochemical adaptations in their athletes using 6 or more reps, he or she should prescribe fewer sets. Here are three workouts that vary the number of sets according to the qualifications of the client: Beginner A1. EZ Bar Reverse Curl A2. Parallel Bar Dips B1. DB Zottman Curl B2.

Here are a few: 1. Training Goal Using the concept that sets are inversely proportionate to the number of reps, let’s add to our chart: Strength QualitySetsRepetitions Relative Strength 6-12 1-5 Functional Hypertrophy 5-10 6-8 Hypertrophy 4-8 9-12 Strength Endurance 3-6 13 + Sometimes there is a need for specialized work that will warrant a greater-than-normal number of sets, such as 8-12. In this case, you must consider that the number of exercises consequently needs to be reduced. For example, alpine skiers tend to lose hamstring strength during the competitive season. Further, the torque-producing capabilities of their quadriceps may rise during the competitive season, despite the fact that little strength training is normally performed. Those gains in quadriceps strength can be due to the overload created by the g-forces held during the high-speed turns inherent in alpine skiing. Thus, the hamstrings/quadriceps strength ratio may decrease just because of the lack of strength training for the hamstrings during the competitive period. To resolve the problem, for an alpine skier it would be wise at the start of the general preparatory period to increase the overload on the hamstrings at the expense of volume of load on the quadriceps. 2. Muscles Trained Just as a student would not expect high results on an exam after a single night of cram studying versus multiple exposures to the study material over a few weeks, an athlete cannot expect motor-learning acquisition from single-set sessions. This is particularly true for lifts such as the power snatch and the jerk when aiming to improve the rate of force development. To improve maximal strength, the body must learn what the new “normal” weight is; and to become comfortable with this new weight, it must be exposed to it several times. If not, the nervous system is like the cramPoliquin International Certification Program- Level 1 Manual © 1982-2016, Poliquin Group 29 ming student in that after the exam -- all knowledge is lost! 3. Exercise Qualities The larger the mass involved in an exercise, the higher the metabolic cost. Thus, lactate production will be much greater with squatting than with forearm work, so it is much easier to tolerate a great number of sets for the forearms than for the squats. Range of motion should also be factored into the workout equation; for example, power snatches from the floor require more flexibility than power snatches from the hang. Similarly, the metabolic cost of a back squat varies greatly between someone who is 5 feet tall and someone who is 6 feet tall. There are estimates of optimal threshold levels for sets and reps for specific lifts. For example, the elbow flexors for relative strength seem to have a minimum of 16 lifts must be performed per workout, and the average rep for each set should not fall below 2.5 reps. There are also superior sets-and-reps combinations that are specific to the exercises intended to be improved. For example, squat poundages in preparatory periods are best driven upwards using a minimum of 7-8 sets of 4-5 repetitions. However, once the individual fails to respond to training volume as a stimulus, intensity becomes the stimulus of choice. In that case, 6-10 sets of 1-3 reps produce the best results. 4. Nutritional Support It is critical to pay attention to nutrition and supplementation to augment work capacity. This will enable an athlete to create greater overloads on the neuromuscular system and thereby accelerate progress. Supplementation is paramount, especially for the natural athlete. There is an abundance of evidence in the scientific literature pointing to the positive influence on work capacity of a variety of supplements. Among these supplements are ribose, creatine, glutamine, and post-workout drinks. Such nutritional support translates into the ability to handle greater average loads when performing multiple sets. 5. Time Under Tension The understanding of “time under tension” is critical for fastest results. For example, the optimal sets of 3RM in the bench press will vary depending on whether they are performed with or without chains attached to the ends of the barbell, which alters the strength curve. With chains, more tension is placed on the muscle fibers during the concentric portion of the exercise. Because there is greater stress during the concentric phase, fewer sets are required since greater microtrauma is generated with each set and there is greater stress on the central nervous system.

Number of Exercises Just as sets and reps are inversely proportionate, so are sets and the number of exercises used in a program. Simply put, the greater the amount of exercises used in a program means the less amount of sets per exercises. Conversely, the less number of exercises will need more sets for each exercise. We can apply this to the nature of the athlete’s sport and its influence of how many exercises per training session are necessary. For example, high jumping requires emphasis on the lower-body musculature, while judo requires the athlete to be able to apply or resist force at many different angles or planes. Thus, a high jumper’s strength training may consist of only 3-4 exercises, whereas a judoka’s may contain 8-12 exercises. Because the high jumper is going to perform only 3-4 exercises, he or she will be able to do more sets for optimal overloading without compromising the ability to recover. Here are two workouts designed to improve relative strength with the number of exercises adjusted to the training goal. Relative Strength – General Population A1. Flat DB Press Pronating A2.

Tolerance and Fatigue Even though multiple sets induce far greater maximal strength gains than single-set training protocols, those gains are asymptomatic in that the adaptations increase with the number of sets up to a certain point. That is, the number of sets is subject to the Law of Diminishing Returns in that the relative reward for every set diminishes with each additional set. This principle explains why, when time is limited such as during the competitive season of a professional sport, it is important to perform 1 or 2 sets of an exercise to maintain -- or in some cases gain, maximal strength. Without the stimulation these sets provide over and above the demands of the sport, this law comes into play, and the athlete’s strength can begin to diminish. This is called the critical drop-off point. Poliquin International Certification Program- Level 1 Manual © 1982-2016, Poliquin Group 31 The basic premise of the critical drop-off point, which was popularized by track and field coach Charlie Francis, is that a coach should never increase quantity of stimulus at the expense of quality. It is pointless to do sets in which the resistance is lowered so much that (a) sufficient tension is not put on the muscle to elicit strength gains, and/or (b) motor units of a lower threshold are trained. These additional “garbage sets” would impede recovery by putting excessive strain on the nervous system, energy stores and neuroendocrine response. The cumulative effect could be overtraining. The critical drop-off point is highly individual, and can even vary from workout to workout. There is empirical evidence, however, that athletes with a high fast-twitch fiber makeup tend to reach the critical drop-off point faster. In contrast, the intake of various substrates such as creatine and ribose will tend to delay the onset of the critical drop-off point. The threshold for the critical drop-off point will also depend on which strength quality the coach is attempting to improve. In the case of maximal strength training, once an athlete reaches a 5-7 percent drop in performance, it is time to move to another exercise or body part. That 5-7 percent drop translates into having to lower the load by the equivalent percentage to maintain a selected rep range (e.g., 6-8 reps), or can be demonstrated by a sudden drop of 2-3 repetitions from one set to the next one. If an athlete has not fully recovered from a workout, first reduce the volume (number of sets), not the intensity. It is a mistake to reduce the weight when an athlete is tired; instead, just decrease the number of repeated efforts performed at that load. Poliquin International Certification Program- Level 1 Manual © 1982-2016, Poliquin Group 32 Chapter 5: Rest Intervals Rest intervals, also known as rest periods, refer to the length of rest between sets and exercises. We can also elaborate on the concept of rest between repetitions within a set. Rest is an important but often underestimated loading parameter. Variables that Influence Rest Intervals When selecting the correct rest intervals in your training program, there are variables that need to be considered. 1. Training Goal “What is the training objective?” is the question the trainer must answer before deciding on the length of the rest intervals. The next question to answer is “Do you want full recovery or incomplete recovery?” The training effects of various rest periods in strength training have been extensively documented in the scientific literature. If you want to maximize impact on the nervous system, full recovery is recommended. When maximal strength is a concern, longer rest intervals will promote strength gains than shorter ones because near-maximal recovery of force generation parallels restoration of energy substrates. The neuromuscular basis of relative strength training methods centers around the use of brief, maximal voluntary contractions. The great voluntary effort normally associated with these brief bursts of maximal exercise recruits the highest-threshold motor units to make use of their greater strength and rate of force development. This is why every repetition must be performed with full concentration and maximum effort, which requires use of long rest intervals. 33 Poliquin International Certification Program- Level 1 Manual © 1982-2016, Poliquin Group 34 The ability to restore neural drive, active muscle tension and energy substrates is a time-dependent process requiring of a non-contractile period of rest following exercise. Rest intervals need to be prescribed based on the training intent, such as relative strength, functional hypertrophy and strength endurance. The length of the rest interval used in heavy resistance training appears to bring about specific changes. Powerlifters, even though accustomed to high-resistance training, have little tolerance to resistance training with minimal rest intervals. Bodybuilders who tend to train in this fashion tolerate this work with greater ease. Note the differences in the rest intervals that are prescribed for these two workouts, one for relative strength and the other for hypertrophy. With all this information, let’s continue to add to details to our loading parameters: Strength QualitySets Reps RestEnergy System Relative Strength 6-12 1-5 180-300 sec Anaerobic Alactic Functional Hypertrophy 5-10 6-8 120-180 sec Anaerobic Lactic Hypertrophy4-8 9-12 90-120 sec Anaerobic Lactic Strength Endurance 3-6 13 + 10-90 sec Aerobic System Relative Strength Program Higher intensities require longer rest periods for optimal nervous system recovery.

Muscles Trained The larger the muscle mass recruited, the greater the length of the rest interval; for example, back squats recruit the largest muscles masses in the human body so they require longer rest intervals. Similarly, exercises that recruit smaller muscle groups, such as the elbow flexors with biceps curls, do not require long rest intervals. Larger muscle groups require longer rest periods due to the amount of energy substrates used by the muscles trained. Note the length of the rest periods in these two groups of exercises.

Exercise Qualities The greater the range of motion, the greater the need for a longer rest interval. For example, deadlifts performed while standing on a 4-inch platform require longer rest intervals than deadlifts performed from the mid-thigh or even the floor. Also, for a given rep range, heavy dumbbell work is more demanding than barbell work; so for a 6RM set, incline dumbbell presses require more rest than incline barbell presses for 6RM. Exercises that are more demanding neurologically require longer rest intervals. Exercises of a highly coordinative nature, such as split jerks and power snatches, need far longer rest intervals than simple isolation exercises such as rotator cuff work. Olympic lifts and their variations demand very precise patterns of force application and smooth coordination as opposed to machine exercises, which are relatively no-brainers. This also explains why heavy dumbbell pressing work requires longer rest intervals than heavy barbell pressing work. Another example would be single-leg dumbbell calf raises versus the seated one-leg calf press. Here are specific workout protocols for deadlifts that have different ranges of motion: Deadlift: Regular Range of Motion A.

Snatch Grip Deadlift on Platform 6 5 4110 180 sec Deadlift: Reduced Range of Motion with Greater Resistance used than with Full Range of Motion Deadlift (Short range of motion translates to greater resistance used over regular range of motion exercise, which means greater rest period) A. Partial Deadlift off Pins Below the Knee 8 5 2210 240 sec 4. Training Age As a general rule, the bigger and stronger the trainee, the longer the rest interval should be. Empirical evidence shows a direct relationship between the length of the rest interval and the weight class of the weightlifter. In other words, the 54 kg lifter will tend to take shorter rest intervals than the super-heavyweight lifter. Conversely, an offensive lineman would rest longer than the running back. Tolerance to short rest intervals with loads in the 60-80 percent range (6-20 reps) is a function of years of accumulated training. Short rest periods are linked to greater psychological anxiety and fatigue, and the lactate buildup resulting from this type of training is tolerated by only the well-conditioned athlete. Consequently, shortening the rest intervals when working with 10RM loads should be done progressively as the buffering mechanisms adapt to increased muscle and blood lactate concentrations. Rest intervals should only be shortened for the advanced trainee, as lactate buildup will interfere with the maintenance of proper technique in the learning trainee. Poliquin International Certification Program- Level 1 Manual © 1982-2016, Poliquin Group 36 Even with neural training, rest intervals can be progressively shortened with no reduction in training weight. Adepts of the training methods used by the Westside Barbell Club and Bulgarian weightlifters are proof of the trainability of this physical quality. By having the antagonistic pairs contracting alternately (e.g., flexion followed by extension) instead of employing agonist contractions alone (precontraction of antagonists), the ability to achieve full motor unit activation (MUA) in a muscle contraction is often enhanced. This has the added benefit of allowing you to double the workload per training unit. A good plan is to alternate exercises working agonist muscles with exercises working antagonistic muscles together, while respecting long rest intervals. For example, after doing a 3RM set of close-grip triceps presses, rest 2-3 minutes, perform a heavy set for the antagonist muscle (e.g., a 3RM to 4RM set of dumbbell curls for the biceps), rest another 2-3 minutes and repeat the above procedure for the required number of sets. Training in this fashion enables an individual to perform a greater tonnage per training unit. This is because alternating antagonist pairs has been shown repeatedly to lower drop-off curves more effectively than traditional standard sets even with complete rest intervals. The paired muscle groups are normally in opposite motor patterns. For example, overhead presses are alternated with forms of chins-ups, and lying forms of presses are alternated with rows. However, you do not necessarily need to pair large motor patterns with other large ones. For example, deadlifts can be alternated with tibialis raises, and chin-ups can be alternated with rotator cuff work. The heavier the athlete, the greater the strain their weight imparts on the cardiovascular system, requiring longer rest periods to recover optimally. The rest periods in the following two workouts have been adjusted to deal with the weight of the athlete. Also, lower intensities may help develop muscular development, and due to what’s known as neurological inefficiency, women and beginners may thrive on using lighter weights with shorter rest intervals.

This section teaches you the true principles that regulate tempo of execution prescription. A Need For a Tempo Prescription If you don’t carefully manipulate all the loading parameters of training you cannot know exactly what type of training stimulus you are applying to the body. One of the most commonly overlooked loading parameters is tempo, or lifting speed. It relates to the “time under tension” of an exercise. Varying tempo is an excellent way to overcome a plateau and shock the body into adapting. Time under tension governs the amount of stimulus a muscle is exposed to. For instance, performing a set of 10 repetitions of squats with 60 kg at a 1-second-up and 1-second-down tempo is quite different from the same weight and reps at a 1-second-up and 4-seconds-down tempo. The difference is in the time exposed to tension. The first variation takes 20 seconds, while the second variation takes 50 seconds. That is a 30-second difference in the time the muscles are exposed to the weight. You should change the amount of time spent on different phases of a lift because it increases intramuscular tension and provides a new or different type of stimulus to the muscles. It is a great way to stimulate further strength development once the body has adapted to a rep range or set range and isn’t making progress. Plus, varied tempo is an ideal way to train for hypertrophy and strength at the same time. Not only should you vary tempo within a lift, but you should also use different lifts that naturally have distinct speeds for optimal training results. Explosive ballistic contractions such as Olympic lifts bring about more central nervous system adaptations while slow-speed lifting with varied eccentric and concentric time phases bring about more metabolic adaptations. Variables that Influence Tempo Prescription Taking control of the tempo of your exercises is a proven method of achieving training goals as quickly as possible. Here are specific variables that influence how you should manipulate the tempo prescription. 1. Training Goal For relative-strength sports, hypertrophic adaptations should be minimized, hence the need to access only high-threshold motor units and keep time under tension to a minimum. By keeping the time under tension 38 short, you ensure that the high energy phosphagens are the main fuel sources for those high-intensity contractions. For relative strength development, normally the athlete utilizes 1-5 repetitions per set. Of course, to keep the total time under tension under 20 seconds, the higher the number of reps per set, the lower the time under tension per repetition should be. For an absolute-strength sport with a high power component, such as hammer throwing, the time under tension for a set should not exceed 40 seconds. Yes, such athletes want hypertrophy, but the hypertrophy must be functional, and this requires that the time under tension be brief. Further, hypertrophy gained by sets of longer time under tension negatively affects performance. Now, let’s put time under tension with the rest of our loading parameters: Strength Quality Relative Strength Functional Hypertrophy Hypertrophy Strength Endurance Sets 6-12 5-10 4-8 3-6 Reps 1-5 6-8 9-12 13 + TUT 0-20 sec 20-40 sec 40-70 sec 50-120 sec Rest 180-300 sec 120-180 sec 90-120 sec 10-90 sec Energy System Anaerobic Alactic Anaerobic Lactic Anaerobic Lactic Aerobic System 2. Exercise Qualities Some exercises by their very nature must always be performed at high speeds while others can be performed at any speed. Exercises that should be performed at only high speeds include the snatch and the clean and jerk, and partial Olympic lifts, such as power cleans. These exercises train the synchronization of muscular chains to improve the rate of force development and involve a multitude of joints that have to be used in a precise order for optimal performance. Normally these are performed at a X0X0 tempo. However, in some instances you may prescribe an isometric pause right in the middle of the concentric range. For example, during the power clean a lifter could pause for 2 seconds once the bar clears the knees. Exercises that can be performed at almost any speed are usually less technically complex and are most often used for building maximal strength and/or hypertrophy. Examples of these exercises include presses, squats and bicep curls. 3. Use of Eccentric and Isometric Contractions An excellent way to target fast-twitch muscle figers is with an isometric pause in the advantageous position (where the body is strongest based on lever length). For flexion exercises, such as biceps or hamstring curls, you should pause in the down position for 1 to 2 seconds. For extension exercises such as squats or bench presses, pause in the up position between the concentric and eccentric motions, when the limbs achieve near lockout position. Of course, varying tempo allows you to perform an isometric pause in the disadvantageous position when you have poor leverage as well. The disadvantageous position for flexion exercises is the up position, and for extension exercises it is the down position. You can imagine that holding the bottom position of a squat for 1 or 2 seconds would provide a valuable training stimulus while increasing intramuscular tension, a combination that can further boost strength development. Poliquin International Certification Program- Level 1 Manual © 1982-2016, Poliquin Group 39 Take note that it is necessary to train high-threshold motor units and develop maximal strength in slower lifts such as the squat, deadlift and bench press to improve faster on movements such as Olympic lifts. For example, you may not be able to power snatch 100 kg unless you can squat about 184 kg. If you can back squat only 160 kg, you may not be able to snatch 100 kg until you increase your squat weight significantly. Varying tempo is an ideal way to work on this. An excellent way for more advanced lifters to overcome plateaus and vary tempo is to train with chains or bands attached to the barbells. This strategy is particularly effective in working the extensor muscles because attaching chains to a barbell will vary the amount of resistance your muscles have to contract against. For example, if you put chains on the ends of the barbell when squatting, the chains will pile up on the floor during the eccentric (or down portion) of the lift, decreasing the weight. As you come up from the squat during the concentric phase, the weight will increase as the chains come off the floor and contribute to your load. This is effective because it increases the weight during the weaker movement (you have less force capability concentrically), requiring you to train through the most challenging point of the lift. A recent study of college football players found that the athletes significantly improved maximal strength and peak power from training with chains and bands. The players who trained with chains and bands improved their 1RM bench press by 10 kg versus players who did a traditional bench press and improved by only 7 kg after a seven-week training program. Researchers also noted that weighted chains supply the added benefit of training the stabilizer muscles because they swing and oscillate throughout the range of motion of a lift. You can use variable resistance on exercises such as deadlifts, squats and bench presses or any exercise in which your progress has stagnated and in which you can reasonably attach chains or bands to the barbell. Eccentric hooks (weights with hooks that hang off the sides of a barbell and drop off once the bottom of the dangling hooks hit the ground) load the lift in the opposite way, making the lift heavier during the eccentric down portion of the lift, where you are naturally stronger. The hooks come off and you can then explode up with less resistance in the concentric motion. Be sure to limit variable resistance training to only one workout out of two, at the most, because it is very taxing on the neuromuscular system. Poliquin International Certification Program- Level 1 Manual © 1982-2016, Poliquin Group 40 Part 3 Basic Anatomy & Structural Balance Chapter 7: Basic Anatomy for the Upper Body Chapter 8: A History of Structural Balance Chapter 7: Basic Anatomy for the Upper Body The Skeletal System The skeletal system includes all the bones and joints. Bones are organs that consist of mineral and protein fibers. They represent the structures that transmit force. There are 206 bones of which belong to either the axial skeleton or the appendicular skeleton. The axial skeleton consists of 80 bones that are found in the midline of the body and include the skull and vertebral column. The appendicular skeleton consists of 126 bones found in the limbs, pelvis, and shoulder girdle. There are five types of bones: long, short, flat, irregular, and sesmoid. A long bone is longer than it’s width, such as the femur or tibia. A short bone is as wide as they are long, such as the wrist bones known as carpals. Flat A joint is the point where at least two bones meet, creating an axis for movement. An axis is a straight line that an object rotates around, and all movements in joints occur in a plane about an axis. Stable joints provide little movement, and unstable joints a permits a wide range of movement. Muscles and Connective Tissue A muscle is a type of tissue that can contract to produce movement or maintain body position. The attachment of the muscle that doesn’t move is called the origin, and the attachment of the muscle that moves is called the insertion. Muscles are also agonist and antagonist; when a muscle contracts it is called the agonist and the opposing muscle is called the antagonist. Muscles can be classified as fast twitch, slow twitch, and mixed fiber depending upon their ability to produce force and resist fatigue. The fast twitch fibers produce the highest levels of force but have the least resistance to fatigue, the slow twitch fibers have the highest resistance to fatigue but produce the lowest levels of force, and the mixed fibers are a compromise between the qualities of the fast twitch and slow twitch fibers. Tendons are fibrous connective tissue that attach muscles to bone so that the bone can move. Ligaments are fibrous connective tissue that attached bone to bone, thus providing stability. 42 Movement Terminology Cardinal Planes intersect the body at its center of mass and divide it into three planes. The frontal plane separates the body into front and back halves, the transverse plane divides the body into top and bottom, and the sagittal plane divides the body into right and left sides. One way to determine the origination of a movement is with planes of movement, of which there are the following seven: • • • • • • • • Anterior = front Posterior = rear Proximal = close Distal = far away Superior = above Inferior = below Medial = towards the midline of the body Lateral = away from the midline of the body The following are terms that describe the types of movements that occur in the human body. -- Flexion: joint angle decreases -- Extension: joint angle increases -- Adduction: movement towards the body -- Abduction: movement away from the body -- Rotation: pivoting movement around a body part -- Circumduction: moving in a circle around a joint -- Pronation: rotation of the foot or forearm so that the sole or palm face down -- Supination: rotation of the foot or forearm so that the sole or palm face up Levers influence how much force is produced during a movement. The fulcrum of a level is the joint being moved, the attachment of the muscle is the point of force application and the point of resistance is where the resistance is moved. There are three types of levers, first class (fulcrum is in the middle, like a pair of scissors) second class (fulcrum and resistance on one same side, like a bottle opener), and third class (fulcrum is at one side and the resistance at the other, like a pair of tweezers). Center of Balance is where the body’s mass is balanced. From a standing position, this position is about in the middle of the foot. Center of Gravity is the point where all the mass is focused. From a standing position, this is about a few inches behind and above the naval. Force is the quality that enables an object to change it’s position. Compression occurs when the body is positioned between load and an immobile surface. Tension is a stretching force, and as such is the opposite of compression. Torque is a force applied in a rotational manner, and shear is when two parts of the body are pushed in opposite directions. Poliquin International Certification Program- Level 1 Manual © 1982-2016, Poliquin Group 43 Prime Movers, Stabilizers and Decelerators The agonist is the muscle that causes the primary movement, and the antagonist is the opposite muscle that is usually relaxed during this movement. To maintain structural balance, each muscle has an optimal relationship with other muscle groups. For example, some trainers suggest the shoulder Internal Rotators/External Rotators have a ratio of 3:2. In PICP, we use the following seven primary exercises to determine upper body structural balance. These were those exercises: 1. Close Grip Bench Press 2. Incline Bench Press 3. Supinated Chin-up 4. Press Behind Neck 5. Scott Barbell Curl 6. Lying Triceps Extension 7. Standing Reverse Curl Here are those exercises broken down into prime movers (muscles primarily responsible for producing movement) followed by other muscles that contribute to the movement: 1. Parallel Bar Dips = Deltoids 2. Bi-acromial Bench Press = Triceps 3. Incline Bi-acromial Bench Press = Anterior Deltoids 4. Supinated Chin-ups = Elbow Flexors 5. Press Behind Neck = Medial Deltoids 6. Seated Scott Curl EZ-bar Curl = Elbow Flexors 7. Standing Reverse Curl = Elbow Flexors We have since expanded the structural balance program to include the following four exercises to provide a more complete assessment of structural balance that act as stabilizers. Stabilizers are muscles that support a body segment so that the prime movers can work. For example, the bent-over trap 3 raise doesn’t contribute to force production but stabilize the shoulder structure so that deltoids, triceps and other muscles can perform movements. Here are those exercises. Flat Powell Raise = Rhomboids Bent-over Trap 3 Raise = Lower Trapezius Elbow on Knee External Rotation = External Rotators of Shoulder Bent-over Lateral Raise = Rear Deltoids Here are the prime movers of these exercises. Again, other muscles are involved in these movements, but these are the ones that contribute the more force to the exercise. For example, if a wide grip was used in the bench press rather than a Bi-acromial grip, the pectoralis major would take over as the prime mover. Poliquin International Certification Program- Level 1 Manual © 1982-2016, Poliquin Group 44 Flat Powell Raise = Rhomboids Bent-over Trap 3 Raise = Lower trapezius Elbow on Knee External Rotation = External Rotators of Shoulder Bent-over Lateral Raise = Rear Deltoid Decelerators are muscles the ensure joint integrity by acting in opposition to the prime movers. For example, the elbow on knee external rotation decelerates the humerous (upper arm bone) during throwing movements. If these muscles are weak, the joint could hyperextend or could decelerate the arm too soon, thus reducing power. Strength Curves, Resistance Curves and Torque Open chain exercises are those in which the body is motionless and a limb moves. A closed chain exercise is one in which the limb stays motionless and the body moves. A bench press is considered an open-chain exercise whereas a push-up is considered a closed chain exercise. One practical way to organize exercises is according to whether they involved pulling or pushing movements, and whether then work the front (anterior chain) or rear (posterior chain) of the body. Here are these four types of upper body movement patterns and examples of each with their prime movers: Horizontal Pulling (Rhomboids) Seated Cable Row Suspension Horizontal Pull-ups Dumbbell Row Bent-over Row Horizontal Pushing (Pectoralis Major) Bench Press, Wide-grip Supine Dumbbell Flyes Pec Dec Cable Crossover Vertical Pulling (Trapezius) Upright Row Shoulder Shrug Power Snatch from Hip Power Clean from Hip Vertical Pushing (Deltoids) Military Press Press Behind Neck Lateral Raise Push Jerk A pronated grip rotates the hands palms down, and a supinated grip rotates them palms up. A semi-supinated grip turns the palms facing each other, and a mixed grip has one hand supinated and the other pronated. Poliquin International Certification Program- Level 1 Manual © 1982-2016, Poliquin Group 45 A supinated grip increases the involvement of the biceps, and a pronated grip increases the involvement of the forearms, especially the biceps muscle called the brachialis. A strength curve describes how much force a muscle can exert at specific joint angles. In contrast, a resistance curve describes how much resistance an exercise places on specific areas of the strength curve. There are three types of resistance curves: low range, midrange, and end range. More specifically, the start of an exercise is the low range, the middle portion is the midrange, and the finish is the end range. Torque can be thought of as the ability of muscle to cause a lever, such as an elbow joint, to rotate a movement arm, such as a lower arm bone. In training the arms, torque is affected by how the elbows are positioned in relation to the body. Change the torque and you change the resistance curve of an exercise. Also, because the line of pull changes with the elbow position, by varying your elbow position you will emphasize different areas of the muscle. Applying these definitions to biceps training, with a standing biceps curl your muscles encounter the most resistance at the midrange of the movement when your elbows are alongside the body. With a Scott curl your elbows are in front of the body, resting on a bench, you encounter the most resistance at the beginning of the exercise. When your elbows are behind your body, such as with a dumbbell incline curl, you encounter the more resistance at the top range of the movement. It follows that to stimulate total arm development your workout could include Scott Curl, standing barbell curl, and dumbbell incline curl. For the triceps, positioning the elbows overhead emphasizes the end range of the resistance curve; an example of such an exercise is a hairline press performed in a power rack. With your elbows behind your body, such as occurs with dips, the torque on the exercise changes so the exercise is most difficult at the midrange of the movement. With your elbows alongside your body you emphasize the low range of the resistance curve. A triceps pressdown is an example of such an exercise. As such, to create maximum development of the triceps your workout could include hairline presses (pin press), dips, and triceps pressdown. There is controversy about whether an individual should just to full range-of-motion exercises or a combination of partial range-of-motion exercises and full range-of-motion exercises. Full range of motion exercises are appropriate for all training populations. However, partial range of motion exercises have value for overcoming plateaus in training and also for sports specific training. For example, for an individual who has trouble locking out a bench press after passing the sticking point, he or she could perform board presses to correct that weakness. However, these athletes should still occasionally perform full-range exercises to prevent muscle imbalances. Poliquin International Certification Program- Level 1 Manual © 1982-2016, Poliquin Group 46 Chapter 8: A History of Structural Balance Structural balance is the assessment method that forms the core of the first two levels of the Poliquin International Certification Program. The basic premise is that any training program, whether it’s for optimal physical fitness or for improved athletic performance, needs to address specific ratios of strength imbalances. As a bonus, maintaining structural balance will help prevent injuries. Here’s an example of the value of restoring structural balance: Several years ago, almost all the players on a Canadian national volleyball team were suffering from patellar tendonitis. Patellar tendonitis is a chronic swelling of the tendon that connects the kneecap to the lower-leg bone. Two months after the team began emphasizing the vastus medialis oblique (VMO) in their workouts, structural balance was restored and the patellar tendonitis went away in all but one of the team members. Knee injuries are of particular concern for women and girls. The American Orthopedic Society for Sports Medicine reports that each year more than 20,000 high school girls suffer serious knee injuries, most involving the ACL. Balancing the muscles surrounding the knee, especially the VMO, can be an extremely valuable step in preventing this devastating injury. However, the concept of structural balance extends beyond injury prevention. Sergey Bubka was a pole-vaulter whose training is discussed in the book, Soviet Training and Recovery Methods by Rick Brunner and Ben Tabachnik, PhD. Included in this book is a table of eight strength and conditioning tests correlated to pole vault performance that Bubka regularly performed throughout his career. Two of the strength tests in this table include results in the snatch and the bench press. Here is the yearly progression of Bubka’s results (in kilos) in the snatch from 1975 (at age 11) to 1984: 25, 35, 40, 45, 50, 60, 70, 80, 85, 90. In that same period, his bench press progressively improved from 20 kilos to 110. Bubka and his coaches believed that by increasing his results in these eight tests he would develop the athletic qualities he needed to be the best in the world. Sure enough, Bubka won the gold in the pole vault at the 1988 Olympics, and during his career he broke 35 world records. The concept of structural balance is used in the program design of weightlifters. The two lifts contested in weightlifting are the snatch and the clean and jerk, but to improve performance in these lifts weightlifters usually perform many assistance exercises, such as squats. For example, one component of the clean and jerk is recovering out of the bottom position when the athlete catches the weight on their shoulders, which equates, basically, to a front squat. As such, the front squat is considered an appropriate assistance exercise for the clean One ongoing controversy in weightlifting concerns the relationship between squats and the lifts, as reported 47 by Bud Charniga from many translations of Russian weightlifting textbooks and from personal conversations. Examples include Americans Mark Henry, who could front squat 325 kilos and clean and jerk 220 kilos, and Shane Hamman, who could back squat 457 kilos and clean and jerk 237 kilos. Likewise, Russia’s Aslanbek Yenaldiev reportedly squatted 455 kilos, but at one competition during that time he was unable to rise from a 240 clean. In contrast, Russia’s Olympic champion Yuri Zakharevich could front squat 250 kilos but could clean and jerk 250.5 kilos and clean 265 kilos. And the great Vasily Alexeev, who clean and jerked 256 kilos, claims never to have squatted more than 270 kilos. In commenting on such ratios, Charniga said, “The strength of the hamstrings (in performing flexion at the knee) in relation to that of the quads is critical to the speed with which the action of shifting the knees under the bar occurs. Likewise, hamstring strength (in stabilizing the hip) is crucial as the shins straighten during the first phase of the pull. So, one needs to be careful not to create a significant imbalance in strength between the quads and hamstrings.” To add punch to his message, Charniga shared a pithy comment he’d heard from former world record holder in weightlifting Alexander Kurlovitch: “A lot of squats adversely affect speed.” Canadian weightlifting coach Pierre Bergeron has trained numerous Olympians and competitors in the World Championships. One of his success stories is Maryse Turcotte, who placed fourth at the Sydney Olympics and was a three-time medalist at the World Championships. To illustrate how to determine structural imbalances in this sport, Bergeron provided the following optimal ratios of the snatch and assistance exercises for an athlete who can clean and jerk 100 kilos: Snatch: 80 kg / 82 kg Power Snatch: 72 kg / 74 kg Snatch Pulls (sets of 3): 95 kg / 100 kg Power Clean: 88 kg / 92 kg Jerks off the Rack: 103 kg / 105 kg Clean Pull: 115 kg / 120 kg Front Squat: 115 kg / 120 kg Back Squat: 128 kg / 132 kg Deadlift: 138 kg / 145 kg Shoulder Shrug (sets of 6): 150 kg / 155 kg Standing Press: 48 kg / 52 kg The following norms are used by several national teams in Canada: Olympic Total: 178 Snatch: 78 Clean and Jerk: 100 Power Snatch: 70 Front Squat: 105 Back Squat: 123 Power Clean: 90 Seated Press: 50-55 Further, tests of power such as the vertical jump and standing long jump have been used to ensure that the training program is not adversely affecting speed. Let’s focus on what these ratios represent and how they Poliquin International Certification Program- Level 1 Manual © 1982-2016, Poliquin Group 48 can affect program design. The power snatch is considered a strength exercise for the snatch, and its relationship to the full movement should influence how an athlete’s training should be modified. For example, if an athlete’s power snatch is nearly the same as the snatch, this may suggest that the athlete needs to work on speed. To accomplish this, the athlete could perform more snatches and snatch-related lifts at lighter percentages (70-80) and fewer sets in the heavier percentages (90-100), as well as a lower volume of squats to allow for more complete recovery from training. The original results could also indicate the athlete has poor technique, or that there is a structural imbalance that prevents optimal technique from being executed. For example, because a lighter weight is used in the power snatch compared to the snatch, it is easier to maintain proper back position at the start of the exercise. If a lifter is rounding their back at the start of the snatch due to weakness in the lower back or hamstrings, this technical problem might be resolved by performing assistance exercises such as deadlifts or back extensions. There are many factors that will affect the percentages used for structural balance. One is the size of the athlete. Heavier weightlifters, especially the super heavyweights, often cannot achieve the extremely low receiving positions in the snatch and clean that lighter lifters can. Further, their larger size also can affect the speed at which they can move under the barbell. The result is that heavier athletes have to pull the barbell to a relatively greater height to catch the barbell during the snatch and clean; this will create differences in the ratios of the power movements compared to the classical lifts. Another benefit of structural balance that makes a difference in weightlifting is confidence. Let’s say a male weightlifter snatches 100 kilos and his best power snatch is 80 kilos. If during the next training cycle he power snatches 85 kilos, he will go into his next competition knowing he is physically strong enough to break his personal record. Trainers and coaches must precisely prescribe the programs that will help correct structural imbalances. Keeping this concept foremost among your goals will enable you to create logical workout plans. Not only is structural balance essential for your athletes, it distinguishes a great program from one that is merely good.
