Fitness Components & Testing Purpose of Fitness Testing. Pre-Tests (Prior to training): To identify strengths and weaknesses. For planning an appropriate training program. To assist with goal setting and motivation. Post-Test (During and after training) To monitor and assess effectiveness of the program. To monitor the progress of the athlete To identify areas of the training program that need modifying. Types of Fitness Tests Laboratory tests are those tests conducted under clinical laboratory conditions. They are the preferred means of assessing fitness components (especially for elite athletes) because they provide the most accurate indication of functional abilities. Disadvantages : laboratory tests often require the use of expensive and sophisticated equipment, controlled environments, qualified personnel and considerable amounts of time to complete, so they can be prohibitive to use. Field tests are an easily administered alternative using readily available and inexpensive equipment. They provide reasonably accurate estimates or predictions of fitness levels. They also allow simultaneous testing of large groups. Disadvantage : Not as accurate as laboratory tests. Criteria for selecting fitness tests Relevant and Specific to the particular activity, fitness components and energy systems used or required in a given activity. Eg cyclists should do cycling tests, runners, running tests etc. In simple terms the test should as closely as possible simulate or replicate the game or performance situation. Valid and Reliable. The tests should actually measure what they claim to measure. A test claiming to measure aerobic capacity should be of sufficient duration to test the aerobic system. Tests must be reliable — that is, it must be able to be replicated with consistently accurate results. Interpretable and Comparable. Meaning the athlete should receive feedback about: • what the results represent (good, average or poor performance) • how the results compare with previous results • how the results compare to those of other athletes in the reference group • the consequences and implications of the results. Fitness Tests Battery The term fitness test battery refers to a selection of tests that have been grouped to provide a comprehensive fitness profile. These test batteries are often formulated by sporting bodies to provide a common set of tests for teams and individuals from within that sporting field. Two fitness test batteries that are widely used within Australian schools are the 1997 ACHPER Australian Fitness Education Award and the Sport Search Fitness Program. Advantages of using a fitness test battery First, a test battery has usually been checked for reliability and validity, and arranged to avoid double testing of the same component. Second, batteries often provide a means of evaluating results on the basis of normreferenced standards or criterion-referenced standards. They may also provide a way of calculating an overall score for each participant. Further, test batteries serve as common denominators among groups. Disadvantage is that test items may not always be specific to a sport’s requirements. Selecting individual tests can produce the most customised group of tests. Fitness Testing Protocol Pre-Testing procedures (Before any fitness testing) The following is a checklist of recommended procedures and precautions: The individual is fully informed about and familiar with the procedures and format of the test (s). They have not consumed food within two hours of the testing. They are wearing appropriate clothing and footwear. They have avoided heavy or intense exercise on the day before testing. They have given consent and obtained appropriate medical clearances. Post-Testing procedures To gain accurate post test data the following conditions must be met: Test conditions should be replicated including: Time of day Temperature Order of tests Physical and mental states. Muscular Strength Definition: 'The force that a muscle of group of muscles can exert in a single maximal contraction'. Factors affecting: Cross-sectional area (Larger = more force) Muscle length and joint angle. (120 degrees = best angle for force application) Fibre type (White fibres apply more force) Sex (Males have larger x-sectional area) Muscle type (Pennate muscle allows greater force. Fusiform allows greater range) Speed (As speed of contraction increases amount of force decreases) Muscular Strength (cont..) Muscular Strength Tests. Handgrip dynomometer.

Definition ; ' The ability to keep performing tasks using the whole body for extended periods where the energy is produced aerobically '. (Considered one of the most important fitness components) Factors effecting; Oxygen delivery to the muscles The efficiency of the heart to blood. The efficiency of the lungs to take in air. Diffusion capacity at the alveoli Ability to remove wastes such as CO2. Aerobic Capacity (cont…) Aerobic Capacity Tests: Vo2 max laboratory tests Usually on a treadmill and requires sophisticated equipment to measures actual oxygen uptake. They are usually maximal tests but can also be of a sub-maximal nature. Lab tests are not commonly used. Advantages of maximal tests : Very accurate. Accurate norms available. Disadvantages of maximal tests : Require costly equipment, are extremely stressful and therefore dangerous to certain individuals, are time consuming etc. Field tests: These are based on the assumption that there is linear relationship between heart rate and oxygen uptake and work rate and oxygen uptake. They are often submaximal test, but certain field test can be of a maximal nature. Estimates of Vo2 max can be made using data from sub-maximal exercise by predicting oxygen uptake on the basis of this relationship Advantages of sub-maximal field tests : Easy to administer, less demanding therefore safer, don’t require expensive equipment or facilities etc. Disadvantages of sub-maximal field tests : Less accurate, fewer reliable norms. Aerobic Capacity (cont..)

Vic Fit agility test. Squat thrust test. Semo agility test. Sports: Any sport which requires sharp directional changes with speed and balance. This includes most team sports in evading the opposition or recovering quickly after falling over. Other sports such as martial arts, wrestling, judo, boxing, tennis and gymnastics also require a high level of agility. Neuro-Muscular Fitness Components Definition : The term ‘neuromuscular’ refers to the interplay of the nervous and muscular systems. Neuromuscular fitness influences a players’ ability, for example, to control a gradual or sudden shift in balance, to react quickly to changing circumstances and/or to efficiently co-ordinate a series of movements. There are 3 key Neuromuscular Fitness Components Balance Reaction time Co-ordination Neuro-Muscular Fitness Components Balance is the ability of the body to remain in a state of equilibrium while performing a desired task. There are two recognised types: Dynamic balance, which involves keeping the body’s balance under control while moving Static balance, which involves keeping the body’s balance under control while not moving. Important for: • running a bend in a 200-metre athletic race • sprinting down the sideline in a Rugby Union game • performing a 60-second aerobics routine • performing a handstand in a gymnastics routine • standing on one foot while shooting at the goal in netball. Jeff Farmer is displaying excellent ‘Dynamic’ balance as he changes direction Balance is one of the discriminating characteristics of elite and average performers. Neuro-Muscular Fitness Components Reaction time is the speed with which an individual can react to an outside stimulus The average reaction time is 0.2 second. It the ability of the brain to react to various outside input sources, process them, select a response, then activate the expected muscular response. Important for: • reacting to the starter’s gun in a sprint race • deciding which player is in the best position to receive a pass in basketball • judging the probable direction of the ball from an opponent’s back swing in tennis. Neuro-Muscular Fitness Components Coordination is the ability to link together a series of muscular movements so they appear to be well controlled and efficiently executed. Important for: • dance, aerobics and ballet • discus throwing • hitting a cover drive for four in cricket • scoring from a netball shot • spiking in volleyball • all routines in gymnastics. It is difficult to contemplate any activity that does not require coordination to some extent. We tend to take for granted our ability to connect a number of closely or loosely linked movements, which result in varying degrees of expertise. Body Composition Body Composition Measurements. Body composition refers to the relative proportions of bone, muscle and fat within the body. It can be assessed in a number of ways, including underwater weighing (hydrodensitometry) and skinfold measurements. Other methods to identify fat proportions and appropriate body weight include : Body mass index . Waist to hip ratio. Body Typing is also a means of assessing body composition. The End
