Derek Crowe 10 26 16 Kin 247 Assignment 2 Fall 2016 Due Friday October 28 2016 by 5 00PM Cardiorespiratory endurance can be assessed in many ways In class we have seen various methods researchers have used to measure cardiorespiratory fitness in their studies This assignment will provide you with the opportunity to assess your own cardiorespiratory fitness For this assignment spelling and grammar will be taken into account in the final grading so please proofread your work before handing it in If you have questions please attend office hours or ask during class Turn in the completed form and the answers to the questions Assignments are due as a paper copy and submitted to Turnitin on Moodle by 5pm on October 28 2016 Answers should be typed and in complete sentences Instructions and Questions Part A 1 You can work with a partner for this activity but each person must perform the test and complete the answers to the questions on his her own 2 As we will be using the Body Shop in Totman you will need to fill out the Body Shop forms i e Consent Physical Activity Readiness Questionnaire PAR Q if you have not already done so Copies of these forms are available on Moodle and at the Body Shop 3 You will sign in on the class roster with the staff in the Body Shop and they will check to make sure you have the correct forms filled out The Body Shop hours are as follows Monday Thursday 7 am to 9 pm Friday 7 am to 6 pm Saturday 10 am to 4 pm Sunday 12 pm to 4 pm 4 You will need to download a free metronome app to use for the test The metronome will help you keep time with the step count that is required You can also use a laptop with a free metronome website http www metronomeonline com You will also need a stopwatch or clock 5 At the Body Shop you will create a 12 step from 8 purple risers 4 on each side and 1 green platform see picture below Figure 1 Step set up for cardiorespiratory fitness test You will also need a metronome a stopwatch clock and a chair 5 The metronome should be set at 96 beats min which will allow you to step up 24 times minute onto the step Each time you step up and back down is 4 counts or beats The lead foot can change during the test 1 up 1st foot 2 up 2nd foot 3 down one foot 4 down other foot Figure 2 1 up 2 up 3 down 4 down 6 Begin the metronome You will step up and down to the rhythm continuously for 3 minutes Use the stopwatch to keep track of the time 7 Immediately after the 3 minutes sit down and quickly find your pulse Record your maximal HR by counting your pulse for 15 seconds immediately after you stop stepping Multiply by 4 to get the HRmax in beats minute 8 One minute after you stop of exercise find your pulse again and count how many pulses you feel for 15 seconds Multiply by 4 to get the HR recovery b min Record this number below under 2 Find your rating in the tables below 1 Use the maximum heart rate HRmax and following equations to calculate your estimated VO2max 15 second count immediately following exercise 33 beats 15 second count X 4 HRmax 132 bpm Males VO2max ml kg min 84 841 0 3143 x HR Females VO2max ml kg min 64 209 0 2021 x HR VO2max 43 35 ml kg min 2 Use the data you recorded for the HR recovery to answer the questions 15 second count 1 minute following completion of exercise 23 beats 15 second count X 4 HR recovery 92 bpm Using the tables at the end of this document and your age what category was your HR recovery response Above Average What happens to the HR recovery number as fitness decreases As fitness decreases the HR recovery number will go up Less fit correlates to longer recovery Is this trend the same for women as men Yes If fitness decreases then your HR recovery number will still go up regardless of sex 3 Graph and describe the relationship 1 between HRmax and VO2max and 2 between HRrecovery and VO2max Label each axis and include proper units on each 1 2 High High HR Recovery bpm HR Max bpm Low VO2 Max ml kg min High What this graph is telling us is that when you have a low VO2 max you will have a high Hear Rate max Vice versa when you have a high VO2 max you will have a low Heart rate Max Low VO2 Max ml kg min High What this graph is telling us is that when you have a low VO2 max you will have a high Hear Rate recovery number Vice versa when you have a high VO2 max you will have a low Heart rate recovery number 4 What factors may decrease the accuracy of the step test to predict VO2max Explain your answers Coffee Caffeine Caffeine on its own can increase heart rate so doing a moderate activity such as this after consuming caffeine might show a much greater heart rate than without consuming it What you did right before the test For example If you went on a 10 mile run then immediately did this test after your heart rate would be way higher than if you did it from rest because your heart rate would have already been elevated 5 What are 2 advantages and 2 disadvantages to this type of test the test you performed Make sure that you explain why you think these are advantages and disadvantages Advantages Easy As far as finding your VO2 max and Max Heart rate this is a very quick and simple way of doing it Cheap You don t need any high tech equipment to do this test Disadvantages Accuracy While this test may give us a general idea of the results it is not nearly as accurate as doing it with some of the more advanced pieces of equipment we have available Mistakes It is so easy to make one small mistake in this test that could drastically effect all of the results I myself had to do the test 3 different times to finally get the correct results 6 Describe 3 physiological factors that determine not influence VO2max Age Being younger you will typically have a better VO2 max than an older person Gender Males generally have a higher VO2 max than females Weight The more someone weighs the greater VO2 max they typically have Instructions and Questions Part B Metabolic calculations are another way to estimate the oxygen consumed during exercise They can be used to estimate submaximal or maximal oxygen consumption They are typically comprised of 3 components 1 the horizontal component 2 the vertical component and 3 the resting energy expenditure Below is the prediction equation for stepping Use it to estimate the volume of oxygen you consumed …
