Question 1

what is the purpose of measuring resting heart rate?

Answer 1

to examine the stress placed on the cardiovascular system at rest to provide the body with oxygen and nutrients

Question 2

what are the steps of measuring resting heart rate? (3)

Answer 2

1. ask the subject to lay flat on their back
2. wait several minutes to allow their heart rate to relax and stabilize
3. measure heart rate using the carotid, radial, and sternal method

Question 3

how do you measure resting heart rate using the carotid method?

Answer 3

• position your index and middle finger over the carotid artery (the neck area)
• start the stopwatch and the first heartbeat should be counted as “0”
• count the number of beats over a 15 second interval and multiply the number by 4 to convert it to BPM

Question 4

how do you measure resting heart rate using the radial method?

Answer 4

• position your index and middle finger over the radial artery below your wrist
• start the stopwatch and the first heartbeat should be counted as “0”
• count the number of beats over a 15 second interval and multiply the number by 4 to convert it to BPM

Question 5

how do you measure resting heart rate using the sternal method?

Answer 5

• position the stethoscope over the sternum or just to the left of the 2nd intercostal space
• start the stopwatch and the first heartbeat should be counted as “0”
• count the number of beats over a 15 second interval and multiply the number by 4 to convert it to BPM

Question 6

what is the purpose of measuring body mass index (BMI)?

Answer 6

to categorize one’s relative health risks based on height (meters) in relation to weight (kg) carried within the body

Question 7

what are the steps for measuring BMI? (5)

Answer 7

1. ask subject to remove their shoes
2. stand under the standiometer with feet together facing forward
3. take in a deep breath and lower the horizontal bar to the top of the head
   - reading is in cm; metres is needed
   - divide number by 100
4. step on the scale and calculate weight
   - reading is in lbs; kg is needed
   - multiply number by 2.2
5. calculate BMI
   - BMI = weight(kg)/height(m) squared

Question 8

what is the purpose of measuring waist to hip ratio?

Answer 8

Question 9

what are the steps in measuring waist to hip ratio? (5)

Answer 9

1. ask the subject to stand in king tut (arms crossed hands on shoulders) with their feet together
2. ask the subject to hold the end of measuring tape at their waist
3. measuring the waist:
   - measure the narrowest point between the bottom of the rib cage and iliac crest
   - ask subject to inhale and take measurement
4. measuring the hip:
   - measure the maximal gluteal protuberance
5. determine waist to hip ratio (WHR)
   - WHR = waist girth (cm)/hip girth (cm)

Question 10

what are the 5 BMI rating categories?

Answer 10

1. underweight: < 18.5
2. normal: 18.5-24.9
3. overweight: 25.0-29.9
4. obese: 30.0-39.9
5. extremely obese: > 40.0

Question 11

what is the purpose of the anaerobic shuttle?

Answer 11

to assess the capacity of the anaerobic system to produce energy through examining decay in speed (m/s) through intermittent repeated sprinting

Question 12

what are the distances of the anaerobic shuttle run?

Answer 12

5 metres, 10 metres, 20 metres

Question 13

what are the steps of completing the anaerobic shuttle? (5)

Answer 13

1. on “go”, run to the 5 metre point then back to the start line
2. immediately turn and run to the 10 metre point and back to the start line, then out to the 20 metre point and back to the start line
3. once back at the start line, record time it took to complete the shuttle and start the 15 second recovery
4. after recovery, complete another shuttle until fatigued or till 6 are completed
5. Record the fatigue index

Question 14

for the anaerobic shuttle run, how do you measure the fatigue index?

Answer 14

if 6 are completed:
- FI = ave x (slowest - fastest)

if less than 6:
- FI = ave x (slowest - fastest) x (6/# shuttles completed)

Question 15

what is the purpose of the yoyo intermittent recovery test?

Answer 15

to assess the power of the aerobic system to produce energy through examining the max distance covered during a graded maximal exercise test

Question 16

what are the steps of the yoyo intermittent recovery test? (5)

Answer 16

1. at the start signal, run to the 20 metre mark by the 1st beep sounds and then run back to the start line before the next beep
2. once shuttle is completed, there is a 10 second rest period
3. go back and forth until unable to keep up the pace
4. each shuttle is denoted by a single beep; each level by a triple beep
5. each participant is given a first warning when they fail to make it back to the start line before the beep, they may continue till they fail a second time

Question 17

what is the purpose of the bench press?

Answer 17

to estimate the max amount of weight (lb) that can theoretically be pushed once during bench press exercise

Question 18

what are the steps of bench press? (3)

Answer 18

1. put your feet flat on the floor and create a neutral spine
2. perform as many repetitions as possible
3. have a spotter on each side of the bar at all times
