One of the best ways to do this is to volunteer to become a participant for a lab. All students will hopefully be able to gain the experience of being a laboratory subject. In order to do so, you must complete the Par-Q to ensure that there are no medical complications, and sign the consent form below. The exact involvement of participants will vary according to each lab, and individuals will be fully informed as to what their participation will require before the beginning of each experiment. Participation is completely voluntary, and students are able to withdraw their participation in a laboratory experiment at any time. Students choice whether or not to participate in laboratory experiments will not affect their outcomes in this course. ____________________________________________________________________________________ I....................................... , have read and understood the above information, and any questions I have asked have been answered to my satisfaction.

Instead, there are hundreds of standard fitness tests used, which can range from elaborate and expensive laboratory tests to simple and inexpensive field tests. Each test also has many advantages and disadvantages that can ultimately determine which is the most appropriate test to perform in each situation. When trying to maximize performance, it is important to determine the athlete's ability in individual aspects of performance. Fitness testing attempts to measure individual components of performance, with the ultimate aim of studying and maximizing the athlete's ability in each component. One of the major benefits of fitness testing is to establish the strengths and weaknesses of the athlete. This is done by comparing test results to other athletes in the same training group, the same sport, or a similar population group. Previous test results of large groups are often published as normative tables. By comparing results to successful athletes in your sport, you can see the areas which need improvement, and the training program can be modified accordingly. This way valuable training time can be used more efficiently. However, beware that some athletes perform well in their sport despite their physical or physiological attributes, and it may not be advantageous to be like them. Objectives To assess individual’s fitness using a number of standardized tests and compare to norms. Procedure Complete RHR, MHR and BP according to instructions in your manual first, then complete the Queen’s College Step Test as a group. Separate into pairs Move around the fitness assessment stations, read the instructions in your manual and complete each test. Ensure that the athlete performs to his/her best and that you record your results accurately. Return to whole group format to complete the beep test 9 _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ 1. RHR Method: i) Ensure that the athlete has been sitting for 20 minutes ii) Use 2 fingers to take either the carotid (either side of the larynx) or the radial (thumb side of the wrist) pulse, count the number of beats in 15 seconds and multiply by 4 to get the bpm Results: Average resting heart rate for males is 72 bpm, and for females is 80 bpm RHR: __________________ BPM 2. MHR Method: i) Use the formula : 220 - age (yrs) MHR: __________________ BPM 3. BP Method: i) Sit the athlete down with their arm supinated and at 90 degrees, resting on a table. ii) Place cuff around the arm just above the elbow, and press start. iii) The cuff will automatically inflate to 180mmHg to stop blood flow through the artery. iv) As the cuff deflates, the machine will detect the systolic pressure- the peak blood pressure that occurs when the heart contracts. These are the first sounds heard after the blood is allowed to pump again. v) The reading on the gauge when blood flow can no longer be heard is the diastolic pressure. Diastolic pressure represents the lowest blood pressure that occurs when the heart relaxes between beats. 10 _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ B.P: Systolic:_______________________ Diastolic____________________________ Compare: Average Blood Pressure For young people – 120/80 mmHg For old people – 140/90 mmHg Level of Severity Systolic Blood Pressure Diastolic Blood pressure Mild Hypertension 140-160 90-100 160-200 100-120 Above 200 Above 120 Moderate Hypertension Severe Hypertension 4. Queen’s college step test Method: i) Have the athlete step up and down from a step (45cm in height) up-up-down down for 3 minutes at the following rate o 45 cm Male - 24 steps per minute /Female - 22 steps per minute ii) 5 seconds after finishing the test measure your carotid pulse iii) Use the calculator at http://www.brianmac.demon.co.uk/queens.htm to get your estimated Vo2 max and compare this to the national averages for your gender and age.

Multistage Shuttle Run (Beep Test) The multistage Shuttle Run (Beep test) as an indirect measure of Vo2 max. The test is split into a series of 1-minute levels. Each level consists of a number of beeps that dictates the pace at which each 20 metre shuttle must be run. The starting speed is 8.5km/hr and increases by 0.5km/hr for each level. Method i) Measure out a 20 metres section and mark each end with a marker cone ii) The athlete carries out a warm up program of jogging and stretching exercises iii) The test is conducted a. The athlete must place one foot on or beyond the 20m marker at the end of each shuttle b. If the athlete arrives at the end of a shuttle before the beep, the athlete must wait for the beep and then resume running c. The athlete keeps running for as long as possible until he/she can longer keep up with the speed set by the tape at which point they should voluntarily withdraw. d.

Two common practices in sports nutrition are carbohydrate loading, and the ingestion of simple sugars immediately prior to exercise, or during a half time break. The effectiveness of these practices has been questioned in the literature, and we will conduct our own tests to examine whether these practices should be used. Outcomes To investigate the effects of carbohydrate loading and glucose intake during exercise on performance Preparatory Procedure Two male and two female subjects will complete each of the carbohydrate loading and the pre-exercise glucose intake tests. All subjects are asked to adhere to the following pre-test instructions: 1) Wear comfortable, loose-fitting clothing 2) Drink plenty of fluids over the 24-hour period preceding the test 3) Avoid food, tobacco, alcohol, and caffeine for 3 hours prior to taking the test 4) Avoid exercise or strenuous physical activity the day of the test; and 5) Get an adequate amount of sleep (6 to 8 hours) the night before the test Carbohydrate loading Subjects are to complete the two-stage, seven day carbohydrate depletion and loading procedure as given on page 117 of the text. Pre-Exercise Glucose Intake Subjects will be given the recommended dosage of glucose water (1 T or 18 g per 240 ml water) twenty minutes prior to test participation according to protocol set out by Byers, Greenwood, Greenwood and Simpson (2006). 29 _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ Trial Procedure Administer the pre-exercise glucose intake solution/ placebo solution to male and female participants for that test. The trial will then be completed by the carbohydrate loading participants first. All control and experimental participants will complete the 12 minute Run (Cooper Test) on treadmills at 0% incline as an indirect measure of Vo2 max. Each participant is to have an allocated carer to ensure their wellbeing throughout the trial. Results Carbohydrate Loading Male 1 Male 2 Female 1 Female 2 Age Trained?

It is perhaps the most popular assessment for peak anaerobic power, anaerobic fatigue and total anaerobic capacity; thus indicating an athlete’s potential in sports requiring high use of the anaerobic energy system. The normal amount of lactic acid circulating in the blood is about 1 to 2 millimoles/litre of blood. The onset of blood lactate accumulation (OBLA) occurs between 2 and 4 millimoles/litre of blood. In non athletes this point is about 50% to 60% VO2 max and in trained athletes around 70% to 80% VO2 max. The lactate threshold indicates the transfer from a predominant use of the aerobic energy system to the anaerobic energy system (glycolysis) and determining an individual’s lactate threshold may be an important indicator of endurance performance and training needs. Outcomes To investigate the anaerobic fitness of athletes from various training backgrounds; and to observe the lactate threshold in trained and untrained athletes. 35 _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ Preparatory Procedure- Wingate Test Participants may be either:: - Male vs female participants - Male or female participants; 1 who is trained in an anaerobic sport; one in an aerobic sport ; and one neutral - elite/ non elite athletes of varying gender All subjects are asked to adhere to the following pre-test instructions: 1) Wear comfortable, loose-fitting clothing 2) Drink plenty of fluids over the 24-hour period preceding the test 3) Avoid food, tobacco, alcohol, and caffeine for 3 hours prior to taking the test 4) Avoid exercise or strenuous physical activity the day of the test; and 5) Get an adequate amount of sleep (6 to 8 hours) the night before the test Assistants will be given the following roles: - Timer- In charge of communicating the stages of the testing procedure according to the stopwatch - Force Setter- Calculates the force required and changes the force settings on the bike accordingly. - Revolutions counter- Counts the revolutions of the bicycle wheel at 5 second intervals during the test. The counter must give the whole number of revolutions. For example, if 10 ½ revolutions have been completed, the counter calls out “10” and counts the half revolution in the next 5 second interval - Heart rate monitor- observes and calls out the heart rate at each 5 second interval - Recorder- Records subject weight, room temperature and the heart rate and number of revolutions as indicated by the counter/ monitor - Lactate measurer- Performs blood lactate measurement at pre-test (before the warm up phase of the testing), post test (immediately following the test at beginning of cool down) and at a 3 minute follow up according to the Lactate Pro instructions Force Settings for Wingate Test 1. Weigh the participant 2. Convert kg to Newtons 9.80665 x kg 3. Categorise the subject a. Active adult female 8.6% of BW; Leg force (N) = BM(N) x 0.086 b.

The following protocol is to be used: i) Warm-up a. 5 minutes of low intensity pedaling at about 50 or 60 rpm interspersed by 5 all out sprints 6 seconds in duration at a progressively increased force resistance ii) Rest a. Rest on the bike by pedaling slowly for a minimum of 2 and a maximum of 5 minutes. iii) Acceleration a. Athlete pedals at 20-50 rpm for 7 seconds at about half of the force that is to be used during the test. b. At the 8 second mark the full predetermined force is to be applied and the athlete continues to pedal at 20-50 rpm for another 7 seconds. iv) Test a. Immediately after the acceleration phase, the individual pedals "all out" at the predetermined force setting for 30-seconds b. The number of revolutions is counted and recorded at each 5 second interval v) Cool down a. Pedal at 50 rpm with the force set at between 5 and 20 N for 2 minutes vi) If the test is to be repeated with the same subject, allow 10 minutes recovery in between tests. 37 _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ Results Wingate Test 1 2 3 4 Gender Age Trained?

Peak Anaerobic Power (PP) Peak anaerobic power is expressed as follows: Peak Anaerobic Power (W) = Work (Force x Total Distance) / (Time in minutes) Force is the amount of resistance (N) added. Total distance is the number of revolutions in the 5 second interval x the distance the wheel travels per revolution. Time is 5 seconds. The result for peak power is expressed in watts (W). For example, if a person’s highest score was 12 revolutions in an interval at a force setting of 45 N in which the wheel’s perimeter travels 6 m per revolution: PP in Watts = [45N x (12 rev x 6m)] / 5 = (45N x 72 m) / 5 = 3240Nm / 5 = 648 Watts _____________________________________________________________ _____________________________________________________________ _____________________________________________________________ _____________________________________________________________ _____________________________________________________________ _____________________________________________________________ _____________________________________________________________ _____________________________________________________________ _____________________________________________________________ _____________________________________________________________ _____________________________________________________________ _____________________________________________________________ ___________________________________________ Peak Anaerobic Power 1. ________________ 2. __________________ 3. _________________ 4. ____________________ 40 _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ 3.

Total Work / Anaerobic Capacity Total work is based upon the total number of revolutions at the end of 30 seconds Work = Force x Distance For example, if the aforementioned athlete completed a total of 52 revolutions: W = N x rev in 30 s x 6 m = 45N x 52 x 6 = 14040 joules = 14.04 kilojoules _____________________________________________________________ _____________________________________________________________ Total Work 1. ________________ 2. _______________ 3. _______________ 4. ________________ 42 _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ 7. Anaerobic Fatigue (AF) Anaerobic fatigue indicates the decrease in power from the Peak to the lowest power performed during the test. The higher the percentage, the greater decline. AF is calculated as follows: AF = (PP – LP / PP) x 100 Peak power output - Lowest 5-second peak power output divided by the Peak power output. Then multiply by 100 to get the percentage decline. Using the previous example, if the PP is 648 w and the Lowest Power [LP] = 300 w: AF = [(648-300) / 648] x 100 = 54% _____________________________________________________________ _____________________________________________________________ _____________________________________________________________ _____________________________________________________________ _____________________________________________________________ _____________________________________________________________ Anaerobic fatigue 1. ________________ 2. _______________ 3. _______________ 4. ________________ 43 _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ Preparatory Procedure- Lactate Threshold Testing All subjects are asked to adhere to the following pre-test instructions: 1) Wear comfortable, loose-fitting clothing 2) Drink plenty of fluids over the 24-hour period preceding the test 3) Avoid food, tobacco, alcohol, and caffeine for 3 hours prior to taking the test 4) Avoid exercise or strenuous physical activity the day of the test; and 5) Get an adequate amount of sleep (6 to 8 hours) the night before the test Two subjects of the same gender, one trained and one untrained are to be tested Subjects should complete a 5 minute warm up including stretching.

This may affect both the prescription and expectations of exercise for older adults. Outcomes To investigate the effect of age and physical activity level on the performance of tests of respiratory and cardiovascular function Procedure There are to be 4 subjects in total. An active and an inactive subject in their 20’s and an active and an inactive subject in their 50’s. All participants complete the Rockport fitness test and will be tested for resting and post exercise Lung Volumes using a spirometer Rockport Walking Test: Subjects warm up. Fit all subjects with heart rate monitors and pedometers at the beginning of the track. Participants walk 1.6 km (1600 metres) as quickly as possibleto be timed with a stopwatch. As soon as the distance is completed, record time and heart rate. Then continue moving in order to cool down Analysis The Rockport walking test gives an estimate of Vo2 max. The formula used to calculate VO2 max is: 132.853 - (0.0769 × Weight) - (0.3877 × Age) + (6.315 × Gender) - (3.2649 × Time) - (0.1565 × HR) Where: Weight is in pounds (lbs).

It is used to assess lung function and is particularly helpful for diagnosing obstructive lung diseases. During this laboratory, we will be using spirometry to understand how lung volumes change during exercise. During resting respiration, only a small portion (about one tenth) of the lung capacity is used. This allows plenty of reserve capacity for those occasions (such as strenuous exercise) when the body requires much greater flow of oxygen to generate energy. Furthermore, the lungs are never completely empty. Even when a lung is removed, and collapses, sufficient air is trapped inside to permit it to float in water. A wet Spirometer measures lung volumes based on the simple mechanical principle that air, exhaled from the lungs, will cause displacement of a closed chamber that is partially submerged in water. The spirometer consists of two chambers: (1) a larger chamber which is filled with water and has a breathing hose attached to it, and (2) a smaller chamber which is inverted inside the first and "suspended" in water. A counterweight and indicator are attached to the inverted chamber. Air blown into the inverted chamber causes it to rise and move an indicator along a scale. The scale is calibrated in liters to give lung volume measurements. Clinical significance of spirometry Measurement of lung volumes and forced expiratory flow rates are useful in the clinical setting. Two types of lung disorders can be identified: 1. Obstructive lung disorders such as bronchitis and asthma. In these conditions, there is an obstructive process in the airways (the bronchi) of the lung and this is detected by a decreased ability to empty the lungs quickly (FEV1/VC ratio) 2. Restrictive lung disorders are characterized by a decrease in lung compliance, in diseases such as emphesyma, which results in reduced alveolar volume. 52 _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ Definitions of lung volumes Lung volume Definition Tidal volume (TV) Volume of air moved during normal breathing (about 0.5 L). Inspiratory reserve volume (IRV) Volume of air that can be forcefully inspired following a normal quiet inspiration. (about 2.5 - 3.5 L). Expiratory reserve volume (ERV) The volume of air that can be forcefully expired after a normal or resting expiration (about 1.0 L). Residual volume (RV) The volume of air remaining in the lungs after a forceful expiration (1.0 L). Vital capacity (VC) The greatest extreme in air volume moved between inspiration and expiration (4.5 L). Inspiratory capacity (IC) The amount of air that the lungs will hold after a normal expiration (i.e. inspiratory reserve + tidal volume). Functional residual capacity (FRC) The amount of air remaining in the lungs after a normal quiet expiration (i.e. expiratory reserve volume + residual volume).

It is important to understand the adaptations that must be made according to the environment in order to maximise training efficiency. Outcomes To investigate the effect of environmental temperature on the performance of submaximal continuous exercise Preparatory Procedure Determine which students will complete which protocols. Pre-testing conditions: All subjects are asked to adhere to the following pre-test instructions: 1) Wear comfortable, loose-fitting clothing: shorts and t shirt only 2) Drink plenty of fluids over the 24-hour period preceding the test 3) Avoid food, tobacco, alcohol, and caffeine for 2 hours prior to taking the test 4) Avoid exercise or strenuous physical activity the day of the test; and 5) Get an adequate amount of sleep (6 to 8 hours) the night before the test Suggestions: a) The same student or all students perform(s) the same activity under all three thermal conditions; b) Three different students of equal training status each perform one of the three protocols; c) 1 male and 1 female of equal training status perform the same activity under all three thermal conditions; 61 _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ Procedure: 30 minutes continuous aerobic exercise Cold Thermo neutral Hot 5 to ten degrees celcius 16-18 degrees Celsius >25 degrees celcius Unheated room Mildly heated room Heated room 62 i) Set the treadmill speed so that the subject achieves a steady state heart rate of 150-160 b/min within the first 5 minutes. ii) Record the speed and maintain it for this exercise session as well as for other protocols iii) Record heart rate, blood pressure, body temperature (oral) and Rate of Perceived Exertion (RPE) every 3 minutes and record any other comments that participants make. iv) The exercise session should continue for 30 minutes.

Here is your chance to develop your own protocol to test out your own hypotheses about exercise physiology in the laboratory environment. You may choose whether to design the lab for use with minimal equipment/ to take full advantage of the laboratory equipment available. This will also give you a chance to develop your skills in designing laboratory experiments that you will need to be competent in when teaching senior students. Students will work in groups of 4 or 5 and will work to design the lab in the first few weeks of class. The design of the labs will be completed and submitted in class in week 4. Students will vote on the lab to use in week 5 and the lab instructions will be uploaded to WebCT for students to download and bring to class in week 6. That group’s lab will be carried out, and students will complete their lab reports in word and submit them online by the 3/9/07. The best lab reports from each group will be uploaded to WebCT so that other groups may view them, and discuss the findings online.

athletes alike in order to improve performance. Caffeine is a common ergogenic aid in that it enhances the contractility of skeletal and cardiac muscle, and helps the body to metabolize fat rather than muscle glycogen stores. It is also a central nervous system stimulant, which can assist in activities that require concentration. Although removed from the IOC restricted substances list in 2004; the legal urine level for athletes used to be 12 µg per mL (IOC standards) or 15 µg per mL (NCAA standards). The ergogenic dose is approximately one half of this-250 to 500 mg (three cups of coffee or six to eight sodas). Outcomes To investigate the effect of caffeine on aerobic capacity Preparatory procedure Subjects are to refrain from consuming caffeine 48 hours before the trial; and are to report to the tutor one hour before the lab begins, where they will be given either 9 mg of caffeine per kg body weight, or a placebo substance. Participants and other students will be blind to the experimental condition. Procedure All participants will cycle at 80% Vo2 Max until exhaustion. The time to exhaustion will be recorded 1) Calculate 80% MHR 2) Start cycling as a warm up and slowly and alter resistance/ speed to obtain a steady heart rate at 80% MHR 3) Start the stopwatch when the steady heart rate is reached 4) Participants may consume small amounts of water during the test 5) Stop the test on the request of the athlete, when they indicate that they have reached exhaustion. 6) Observe the athletes closely for signs of overheating, fatigue, and stop the test if they complain of numbness, or if there is any change in behaviour. 74 _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ Results Participant 1 Participant 2 Participant 3 Participant 4 RPE RPE RPE RPE Gender Age Level of fitness Caffeine?

Fitness testing can be used to effectively show students the changes that occur due to an exercise or training program; and may give teachers a chance to explain the physiological mechanisms behind these changes. Outcomes Students are to repeat fitness testing completed at the beginning of semester in order to measure the changes in their fitness level over a 7 week training period. Procedure All students will be allocated a test to set up/ oversee/ instruct the class in Complete RHR, MHR and BP according to instructions in your manual first, then complete the Queen’s College Step Test as a group Separate into pairs Move around the fitness assessment stations, read the instructions in your manual and complete each test. Ensure that you record your results accurately.

RHR Method: c. Ensure that the athlete has been sitting or lying down quietly for 20 minutes d. Use 2 fingers to take either the carotid (either side of the larynx) or the radial (thumb side of the wrist) pulse, count the number of beats in 15 seconds and multiply by 4 to get the bpm Results: Average resting heart rate for males is 72 bpm, and for females is 80 bpm RHR: __________________ BPM 2. MHR Method: i) Use the formula : 220 - age (yrs) MHR: __________________ BPM 3. BP Method: a. Sit the athlete down with their arm supinated and at 90 degrees, resting on a table. b. Place cuff around the arm just above the elbow, and press start c. The cuff will automatically inflate to 180mmHg to stop blood flow d. As the cuff deflates, the machine will detect the systolic pressure- the peak blood pressure that occurs when the heart contracts. These are the first sound heard after the blood is allowed to pump again e. The reading on the gauge when blood flow can no longer be heard is the diastolic pressure. Diastolic pressure represents the lowest blood pressure that occurs when the heart relaxes between beats.

Multistage Shuttle Run (Beep Test) The multistage Shuttle Run (Beep test) as an indirect measure of Vo2 max. The test is split into a series of 1-minute levels. Each level consists of a number of beeps that dictates the pace at which each 20 metre shuttle must be run. The starting speed is 8.5km/hr and increases by 0.5km/hr for each level. Method i) Measure out a 20 metres section and mark each end with a marker cone ii) The athlete carries out a warm up program of jogging and stretching exercises iii) The test is conducted a. The athlete must place one foot on or beyond the 20m marker at the end of each shuttle b. If the athlete arrives at the end of a shuttle before the beep, the athlete must wait for the beep and then resume running c. The athlete keeps running for as long as possible until he/she can longer keep up with the speed set by the tape at which point they should voluntarily withdraw. d. If the athlete fails to reach the end of the shuttle before the beep they should be allowed 2 or 3 further shuttles to attempt to regain the required pace before being withdrawn e. Record the level and number of shuttles completed at that level by the athlete f. At the end of the test the athletes conduct a cool down program, including stretching exercises Level _________________________ Vo2 Max ____________________ Rating ______________ Compare Use the tables from the first fitness assessment to determine your estimated Vo2 max and associated rating 87 _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ Results Assessment 1-Date: Score Assessment 2- Date: Rating RHR MHR B.P Step test (Vo2 Max) Sit and reach Illinois Agility run Grip strength Standing long jump 1RM Bench Press Vertical jump Sit ups Pushups Beep Test (Vo2 Max) 88 Score Rating _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ Questions: 1.
