Extra Time Fitness Booklet GETTING BACK IN SHAPE!!! 1 HEALTH RELATED FITNESS AT A GLANCE Physical fitness is a dynamic construct in that it is continually growing in importance to everyday life and health. It may be defined as “the ability to perform moderate to vigorous levels of physical activity without undue fatigue and the capability of maintaining such ability throughout life” (ACSM, 2006). The concept of health related physical fitness (HRPF) can be broken down into 5 different components: Cardio-Respiratory Endurance Muscular Strength Muscular Endurance Flexibility Body Composition All 5 of the HRPF components contribute equally, or are in balance, to this fitness-based concept. This booklet will provide you with a brief definition of each component, and will further supplement you with the relevant background information on the importance of each respective aspect of HRPF. Finally, the recommended guidelines on how to improve your overall fitness, by improving each component, will be provided in each section. By increasing your education and general awareness surrounding your own fitness levels and methods to improve the same, you will find it easier to achieve such improvements and the respective goals that you have set for yourself. Get Active, Get Healthy 2 The F.I.T.T. Principle in Developing Fitness Levels In terms of health related physical fitness (HRPF) development, practices are the ‘what to do’s’, i.e. specific applications that fit specific circumstances. Therefore, principles are the ‘why to do’s’, the elements upon which applications or practices are built. The principle of ‘overload’ is one of the key ‘Principles of Training’, and may be defined as the need to work that particular fitness component against a load greater than normal. The intensity of the workload required to produce a training effect increases as the performance is improved in the course of training, and in order to achieve further improvement; the training intensity must be increased. That is, once you have adapted to a workload of the training programme, the workload should be increased. The overload principle is achieved through the use of F.I.T.T.: F - Frequency - how often an individual trains I - Intensity - how hard an individual trains T - Time - for how long an individual trains T - Type - type of training performed This approach will aid in the development of all of the HRPF components, and each one will be covered in detail in each section. 3 The Importance of an Effective Warm Up & Cool Down The warm-up (WU) & cool-down (CD) are very important parts of any physical activity session. There is no doubt that time spent on an effective WU & CD will improve your level of performance & accelerate the recovery process needed before participating again. Warming Up Before beginning any vigorous physical activity, one should prepare the body for exercise. A proper WU before vigorous exercise safely prepares the body for the subsequent workload. A WU can be just a slow version of the activity, i.e. walk before jogging, jog before running, etc. You should warm up at a pace that gets your heart beating at 50 to 60 percent of your maximum heart rate (MHR = 220 – your age), where breathing will be harder than normal, but not as hard as during the actual exercise. Benefits of an Effective Warm Up A WU may help prevent injuries & maximise performance through the following means: Increase the body's internal temperature & the heart rate - the chance of getting injured decreases when the heart, muscles, ligaments & tendons are properly prepared for exertion. Increase the joint's range of movement – warm muscles stretch better & allow greater range of movement for the joints; cold muscles do not absorb shock or impact as well, and are more susceptible to injury. Increased speed of contraction & relaxation of warmed muscles Increased blood flow through active tissues as local vascular beds dilate, increasing metabolism & muscle temperature Dynamic exercises help to reduce muscle stiffness Rehearsal of the movements & skills needed Mental preparation for the event 4 The warm up should start slowly and systematically, and gradually involve all muscles and body parts that prepare the individual for participation. A warm-up normally consists of 4 stages: 1. Gentle loosening exercises 2. Jogging 3. Stretching 4. Event specific exercise The Cool Down The CD is as important as the warm up, however it is often ignored. Cooling down gradually decreases body temperature & heart rate, and speeds the recovery process before the next training session. One should cool down properly after each exercise period, regardless of the type of workout. The CD helps you to taper off gradually before stopping completely. It is equally important to readjust the body from exercise to rest. If you would like a quicker recovery time, start implementing a CD after participation. Don't forget, your body is the best machine on the planet - treat it that way! Benefits of an Effective Cool Down An appropriate cool down will: gently ease the heart/lungs back to resting level aid in dissipation of waste products - e.g. lactic acid reduce the potential for the delayed onset of muscle soreness (DOMS) reduce the chances of dizziness or fainting caused by the pooling of venous blood at the extremities reduce the level of adrenaline in the blood help reduce cases of cramps, soreness, & other problems Therefore, it is important to gradually bring the body back to its resting state by slowly decreasing the intensity of the activity. A 10 to 15 minute cool-down period is generally sufficient to allow heart rate and breathing to return to normal. 5 This should consist of the following: 5 to 7 minutes jogging/walking - decrease body temp & remove waste products from the working muscles 5 to 10 minutes stretching - decrease body temp, remove waste products from the working muscles & to increase range of movement – NB ‘no overstretch’ 6 Cardio Respiratory Endurance Definition The ability to continue to perform strenuous tasks involving large muscle groups for extended periods of time. It is the ability of the circulatory and respiratory systems to adjust and recover from the effects of whole body exercise or work Health Benefits of Cardio-Respiratory Endurance Stronger heart beat Lower heart rate Possible reduction in blood pressure Possible resistance to atherosclerosis Possible improved periphery circulation Quicker recovery after hard work Improved coronary circulation Less chance of a heart attack Greater chance of surviving a heart attack Increased O2 carrying capacity in the blood 7 How to Improve Your Cardio-Respiratory Endurance Frequency of Training: 3-5 Days a week Intensity of Training: 55%-90% of maximum heart rate Type of Activity: Perform any activity that uses large muscle groups, which can be maintained continuously, and is rhythmical and aerobic in nature, e.g., walking-hiking, running-jogging, cycling-bicycling, cross-country skiing, aerobic dance/group exercise, rope skipping, rowing, stair climbing, swimming, skating, and various endurance game activities or some combination thereof. Time: 20-60 min of continuous or intermittent (minimum of 10-min bouts accumulated throughout the day) aerobic activity. 8 Muscular Strength Definition The maximal one- effort force that can be exerted against a resistance. It is the absolute maximum amount of force that one can generate in an isolated movement of a single muscle group. The stronger the individual, the greater the amount of force he or she can generate. Health Benefits of Improved Muscular Strength Greater work efficiency Less chance of muscular injury Decreased chance of lower back pain Improved performance in sports Can help maintain a healthy posture Muscle toning (increase lean body mass) Enhances self-esteem Slows the onset of weakness and frailty associated with aging What the experts say… ‘Resistance training should be an integral part of an adult fitness program and of a sufficient intensity to enhance strength, muscular endurance, and maintain fatfree mass…’ (ACSM Position Stand on Developing Muscular Strength in Healthy Adults) 9 How to Improve Your Muscular Strength Muscular strength may be developed more so in the gym rather than at home, although muscular endurance may be improved by performing simple ‘bodyresistance’ exercises (push-ups, sit-ups, etc.). This will be covered in more detail in the next section. Frequency of Training: The ACSM recommend one set of 8-10 exercises that conditions the major muscle groups 2-3 days per week. However, multiple-set regimens may provide greater benefits if time allows. Intensity of Training: 8-12 repetitions of each exercise is sufficient to allow for development of muscular strength Type of Activity: Compound weights exercises such as squats, lunges and deadlifts are good for developing lower body muscular strength. Similarly, exercises that utilise a number of joints such as the bench press, shoulder press, chin ups and most rowing exercises are good for developing upper body strength. Time: 30- 60 minutes is sufficient time to undertake a weight training session. NB If undertaking a weight training programme, make sure it is designed and supervised by a qualified instructor! 10 Muscular Endurance Definition The ability of the muscles to apply a sub-maximal force to repeatedly or to sustain a muscular contraction for a certain period of time. Health Benefits of Improved Muscular Endurance: Greater work efficiency Less chance of muscular injury Decreased chance of lower back pain Improved performance in sports Can help maintain a health posture Greater ability to resist fatigue Muscle toning (increase lean body mass) Enhances self-esteem Helps reduce CVD risk by enhancing your blood lipid profile (increases the HDL and decreases cholesterol) Develops the slow-twitch fibres in your muscles 11 How to Improve Your Muscular Endurance Muscular endurance can be developed at home as well as at the gym. Frequency of Training: 3-5 Times a week Intensity of Training: 50 – 70% of your 1 repetition-max. Type of Activity: Exercises such as press ups, sit ups or crunches, tricep dips, lunging exercises, squatting exercises and many core stability exercises are great for developing muscular endurance. Some muscular endurance exercises that you could try include: Press Ups Sit Ups For Example Tricep Dips 3 sets of 10-12 repetitions Back Extensions Forward Lunges Time: 30-60 minutes is sufficient to undertake a strength endurance session. 12 Flexibility Definition The functional capacity of the joints to move through a full range of movement. Flexibility is specific to each joint of the body. Muscles, ligaments and tendons largely determine the amount of movement possible at each joint. Health Benefits of Improved Flexibility: Good joint mobility Less chance of muscle injury Prevents lower back problems Helps maintain good postural alignment Muscular relaxation Release of stress and tension Enhanced performance of certain tasks Can relieve pain in some circumstances What the experts say… ‘Flexibility exercises should be incorporated into the overall fitness program sufficient to develop and maintain range of motion (ROM). These exercises should stretch the major muscle groups… Stretching should include appropriate static and/or dynamic techniques.’ (ACSM Position Stand on Developing Flexibility for Health Adults, 1998) 13 How to Improve Your Joint Flexibility Frequency of Training: Before and after your training sessions. Before bed and in the morning is a good time to perform a combination of dynamic and static stretches by themselves. The ACSM recommend performing flexibility training at least 2-3 times a week. Intensity of Training: Static stretches should be help to the point of tension and dynamic exercises should be performed in a smooth and fluid manner. Stretching should NOT be painful!!! Type of Training: Perform a series of dynamic warm up exercises at the beginning of your work out, stretching all the major muscle groups. Perform a series of static stretches after the workout, again, making sure to stretch all the major muscles. Time: Static stretches should be held for 30 - 60 seconds. 14 Some Dynamic Flexibility Exercises: Shoulder Circles Stand tall, feet slightly wider than shoulder-width apart, knees slightly bent Raise your right shoulder towards your right ear, take it backwards, down and then up again to the ear in a smooth action Repeat with the other shoulder Arm Swings Stand tall, feet slightly wider than shoulder-width apart, knees slightly bent Keep the back straight at all times Overhead/Down and back - Swing both arms continuously to an overhead position and then forward, down, and backwards. 6 to 10 repetitions Side/Front Crossover - Swing both arms out to your sides and then cross them in front of your chest. 6 to 10 repetitions Squat Stand tall with good posture holding your hands out in front of you for balance Now bend at the knees until your thighs are parallel with the floor Keep your back long throughout the movement, and look straight ahead Make sure that your knees always point in the same direction as your toes Once at your lowest point, fully straighten your legs to return to your starting position Repeat the exercise 10 to 12 times with a smooth, controlled rhythm Breath in as you descend, and out as you rise 15 Leg Swings - Flexion/Extension Stand sideways onto the wall Weight on your left leg and your right hand on the wall for balance Swing your right leg forward and backward 10 to 12 repetitions on each leg Leg Swings – Abduction/Adduction Leaning slightly forward with both hands on a wall and your weight on your left leg Swing your right leg to the left in front of your body, pointing your toes upwards as your foot reaches its furthest point of motion Then swing the right leg back to the right as far as comfortable, again pointing your toes up as your foot reaches its final point of movement 10 to 12 repetitions on each leg Lunges Standing tall both feet together (starting position) Keeping the back straight lunge forward with the right leg approx 1 to 1½ metre The right thigh should be parallel with the ground and the right lower leg vertical Step back to the starting position Repeat with the left leg 12 to 16 repetitions on each leg 16 Some Static Stretches: Quadriceps Stretch Lie face down on the floor, resting your fore-head on your right hand Press your hips firmly into the floor and bring your left foot up towards your buttocks Take hold of the left foot with the left hand and ease the foot closer to you buttocks Repeat with the right leg You will feel the stretch along the front of the thigh Groin Stretch Sit with tall posture Ease both of your feet up towards your body and place the soles of your feet together, allowing your knees to come up and out to the side Resting your hands on your lower legs or ankles and ease both knees towards the ground You will feel the stretch along the inside of your thighs and groin Front of Trunk Stretch Lie face down on the floor, fully outstretched Bring your hands to the sides of your shoulders and ease your chest off the floor, keeping your hips firmly pressed into the ground You will feel the stretch in the front of the trunk Hamstring Stretch Sit on the ground with both legs straight out in front of you Bend the left leg and place the sole of the left foot alongside the knee of the right leg Allow the left leg to lie relaxed on the ground Bend forward keeping the back straight You will feel the stretch in the hamstring of the right leg 17 Repeat with the other leg Calf Stretch Stand tall with one leg in front of the other, hands flat and at shoulder height against a wall. Ease your back leg further away from the wall, keeping it straight and press the heel firmly into the floor Keep your hips facing the wall and the rear leg and spine in a straight line You will feel the stretch in the calf of the rear leg Repeat with the other leg 18 Body Composition Definition The body’s relative amounts of fat and lean body tissue, or fat free mass (muscle, bone, water). Body weight can be sub-divided simply into two components; fat weight and fat- free weight. Fat free weight consists of all of the tissue of the body except for chemical fat. Obesity is defined as an excessive accumulation of fat weight. Health Benefits of Improved Body Composition: Improved Appearance Muscle is more metabolically active than fat Reasonable fat weight= less strain on heart/ joints Possible improved self esteem and self confidence What the experts say… ‘Based on scientific evidence, there are a number of intervention strategies that can be used to induce and maintain significant weight loss, and these include changes in energy intake and energy composition, increases in energy expenditure through exercise and other forms of physical activity, and, when indicated, the use of pharmacotherapy. Regardless of the intervention approach, it is necessary for these changes in behaviour to be maintained to enhance long-term weight loss outcomes.’ (American College of Sports Medicine, Position Stand on Weight loss and Prevention of Weight Regain in Adults, 2001) Body Composition Health Standards: Classification Essential Fat Storage Fat Overfat Lean Healthy Slightly Over Fat Obese Women (% Fat) 11-14 <12 13-20 21-25 26-32 >32 Men (%Fat) 3-5 <7 8-15 16-20 21-24 25+ 19 How to Achieve Your Optimum Body Composition Seek advice on your dietary habits and maintain healthy eating patterns. Couple these dietary changes with an exercise programme taking these guidelines into consideration. Frequency of Training: Exercise for at least 30 minutes on most or preferably all days. Intensity of Training: Exercise at a moderate intensity. I.E. 55-69 % of your maximal heart rate Type of Activity: Aerobic exercises such as walking, jogging, cycling, swimming and racquet sports are all conducive to weight loss if performed at adequate intensity and for an adequate period of time. Racquet sports such as tennis and squash can also aid in weight loss. Adding resistance exercises such as press-ups, sit ups or weights exercises may also assist you in your weight loss programme. Time: At least 30 minutes is the recommended period to get an effect from your training although if you are on a busy schedule, accumulating 30-40 minutes of moderate intensity exercise during the day may also be of benefit to your weight loss programme. 20
