Conditioning Seasons and Periodization Sports med 2 Inadequate conditioning is one of the major causes of sports injuries Sports Conditioning is a year round endeavor Periodization/Sports Seasons Periodization manipulates training intensity (I), volume (V), and specificity according to the different seasons Prevents injury and peak levels of fitness achieved for competition Cycles Post/Off season Pre-season In-season Periodization As competition approaches… Training shifts from non sport specific activities of high volume and low intensity To Sport specific low volume & high intensity training Periodization Cycles Macrocycle Entire training year Mesocycle Several weeks to several months Depends on the goal of the athlete Microcycle 1 week long could last longer Sports seasons Post-Season (Transition period) Last competition to early off season Unstructured recreational activities Off Season (Preparatory period) Hypertrophy/Endurance phase Low I, high V Develop base endurance Strength phase Moderate I and V levels Sports specific weight training Preseason Power phase High I, low V Sports Seasons In-Season (competition period) High I, low V Skill training Maintenance multiple microcylces Starting high I to low before competition Goal is peak fitness and performance competition day Crosstraining Substitute activities that have carry over value to that sport Prevents boredom Sports Med 2 First used by physical therapists for treating patients who had various types of neuromuscular paralysis • Now used as a stretching technique to increase flexibility Stretching techniques that involve combinations of alternating contractions and stretches Used in rehabilitation to facilitate strength and increase ROM ADVANTAGES Increase muscular flexibility Increase ROM DISADVANTAGES Exercises require a partner Exercises require expertise Passive • The degree to which a joint may be passively moved to the endpoints in the ROM • No muscular contraction is involved Active • The degree to which a joint can be moved by a muscle contraction Isometric • Means to contract a muscle statically without changing its length • This contraction is referred to has “hold” Concentric • The muscle shortens while contracting against resistance • This contraction is referred to as “contract” Passive stretches • Referred to as “relax” Hold-relax • Passive stretch –hold for 10 sec. • Athlete is instructed to “hold and not let leg move” for 6 seconds Athlete resists movement which creates isometric contraction • Athlete relaxes • Passive stretch held for 10 sec. • Repeat 3 times Contract-relax • • • • • Passive stretch –hold for 10 sec Athlete isotonically pushes against resistance from partner-10 sec Athlete relaxes Passive stretch applied and held for 10 sec. Repeat 3 times • • • • Athlete moves body part to point of resistance and is told to “hold” Muscles are isometrically resisted by partner for 10 sec. Athlete relaxes-10 sec Athlete moves body part into farther ROM Slow –reversal-hold-relax Training Variations SAID principle Specific Adaptation Imposed Demands The body will adapt to overcome demands placed on it Decreases potential for injury Ex. Muscle increases in size and efficiency with progressive weight training Principles of Conditioning warm up/cool down Motivation- vary the program Overload-make the system work harder Consistency-regularly scheduled programs Progression-increase intensity w/in athletes ability Principles of Conditioning Intensity-more important than quantity Specificity-specific goals to the athletes sport Individuality-adjust program to the athletes needs Stress-give them time away Safety-educate, proper techniques Muscular Strength, Endurance, and Power As muscular strength increases so does endurance The ability to generate power is more critical to performance than strength or endurance What determines Strength? Muscle Size # of Muscle Fibers Inherited, but strength can still be increased w/exercise Neuromuscular Efficiency Achieved by getting more motor units to fire Biomechanical Factors Tendon placement on bone will determine how much force can be generated What determines Strength? Fast Twitch vs Slow Twitch Slow twitch for endurance muscles Fast twitch for power, and strength Physical activity level Overtraining Psychological and physiological breakdown Physiological changes Increase in size and number of myofilaments Core Stabilization Training Core (center of gravity) Lumbo-pelvic-hip complex 29 muscles Weak core = inefficient movements=injury SLIDING FILAMENT THEORY MUSCLE BREAKDOWN ANATOMY • EPIMYSIUM: COVERS ENTIRE MUSCLE, MADE OF THOUSANDS OF MUSCLE CELLS • PERIMYSIUM: SURROUNDS THE FASCICLE • FASCICLE: MUSCLE FIBER GROUPS, ABOUT 150 FIBERS • MUSCLE FIBERS: LONG, CYLINDRICAL CELLS ABOUT THE SIZE OF HAIR • ENDOMYSIUM: SURROUNDS INDIVIDUAL MUSCLE FIBER • MYOFIBRIL: WITHIN EACH FASCICLE, CONTAINS THOUSANDS CELLS, MAKES MUSCLE CONTRACTION REVIEW: TALK ABOUT EACH PART WITH A NEIGHBOR MORE MUSCLE FIBER BREAK DOWN • SARCOMERE: CONTRACTILE ELEMENT.

Determine repetitions maximum (RM) The max number of reps at a given weight Increase weight by 10% Hand Grips 4 Common Grips Pronated- palms down and knuckles up Supinated- palms up and knuckles down Alternated- one is pronated and the other is supinated Hook – thumb is positioned under the index and middle fingers. Movement, ROM, & Speed When the entire ROM is covered during an exercise, value of the exercise is maximized and flexibility is maintained or improved Repetitions performed slow and controlled increase the likelihood that full ROM can be reached Program Design Designing a resistance training program is a complex process that requires the recognition of many different variables Needs Analysis Evaluation of the sport Determine the unique characteristics of the sport. Enables the strength and conditioning coach to design a program specific to the sport Assessment of the athlete Find out the athlete’s needs and goals • Ex: training status, physical testing and evaluation, training goals Chart 18.1 Classifying resistance training status Resistance training Program Training Status Current Program Not training Beginner (untrained) or just Training Age Training Stress Technique Experienc e/skill <2 months None or low None or minimal 2-6 months Medium basic 1+ year High High began Intermedia Currently training te (moderatel y trained) Advanced (well trained) Currently training Chart 18.2 Example of General training Priorities by sport season Sport Season Sport Practice Resistance Resistance training goal Training Off-season Low High Hypertrophy and muscular endurance (initially); strength and power (later) Pre-season Medium Medium Sport-and-movement-specific (ie. Strength, power, or muscular endurance, depending on the sport) In-season High Low Maintenance of preseason training goal Post-season (active rest) variable variable Not specific (may include activities other than sport skill or resistance training) Exercise Selection Involves choosing exercises for a resistance training program Most exercises involve primary muscle groups or body areas relative to the athletes sport Core exercises • Recruit one or more large muscle areas • Ex: chest, shoulders, back Assistance exercises • Recruit smaller muscle areas • Ex: biceps, triceps, mainly used for injury prevention, & rehab Sport specific exercises • The more similar the training activity is to the actual sport movement, the greater likelihood that there will be a positive transfer to that sport Table 18.3 Examples of Movement-related resistance training exercises Movement Pattern Related Exercises Ball Dribbling & Passing Triceps pushdown, reverse curl, close-grip bench press Ball Kicking Unilateral hip adduction/abduction, knee extension, leg raise Freestyle Swimming Lat pulldown, lateral raise, lunge Jumping Power clean, push jerk, back squat Racket Stroke Dumbbell fly, bent-over lateral raise, wrist curl/extension Rowing Bent-over row, seated row, hip sled Running/Sprinting Lunge, step-up, dorsiflexion Throwing/Pitching Pullover, overhead triceps extension, shoulder internal/external rotation Training Frequency Training status Athletes level of preparedness for training. 3 workouts per week are recommended for many athletes Chart 18.4 Sport season Chart 18.6 Training load and exercise type If the athlete lifts at maximum or near maximum effort they need more rest in-between workouts Chart 18.4 Resistance training frequency based on training status Training Status Frequency Guidelines (sessions/week) Beginner 2-3 Intermediate 3-4 Advanced 4-7 Chart 18.6 Resistance training frequency based on the sport season (trained athlete) Sports Season Frequency Guidelines (sessions/week) Off-season 4-6 Preseason 3-4 In-season 1-2 Postseason (active rest) 1-3 Exercise Order Power, other core, the assistance exercises Upper & lower body exercises (alternated) Push and pull exercises Gives more rest between sets Alternate bench press with lat pull downs The same muscle will not be used twice in a row Supersets and compound sets Supersets: 2 exercises that stress two opposing muscles or muscle areas Compound sets: sequentially performing two different exercises for the same muscle group Volume Depends on the goal of the athlete Chart 18.11 Volume assignments based on the training goal Training Goal Goal Repetitions Sets Strength ≤6 2-6 Power: Single effort 1-2 3-5 Multiple effort event 3-5 Hypertrophy 6-12 3-6 Muscular Endurance ≥ 12 2-3 Rest Periods Related to the load; the heavier the load the longer the rest periods Chart 18.12 Rest Period Length Assignments Based on the Training Goal Training Goal Rest Period Length Strength 2-5 min.
