 LAB 3.1: Assessing Your Current Level of Cardiorespiratory Endurance

Before taking any of the cardiorespiratory endurance assessment tests, refer to the fitness prerequisites and cautions given in Table 3.2. For best results, don't exercise strenuously or consume caffeine the day of the test, and don't smoke or eat a heavy meal within about 3 hours of the test.

The 1-Mile Walk Test

Equipment
1. A track or course that provides a measurement of 1 mile
2. A stopwatch, clock, or watch with a second hand
3. A weight scale

Preparation
Measure your body weight (in pounds) before taking the test.

Body weight: lb *
Age: *
Gender: *

Instructions

1. Warm up before taking the test. Do some walking, easy jogging, or calisthenics and some stretching exercises.
2. Cover the 1-mile course as quickly as possible. Walk at a pace that is brisk but comfortable. You must raise your heart rate above 120 beats per minute (bpm).
3. As soon as you complete the distance, note your time and take your pulse for 10 seconds.

Walking time: min sec *

10-second pulse count: beats *

4. Cool down after the test by walking slowly for several minutes.

Determining Maximal Oxygen Consumption

1. Convert your 10-second pulse count into a value for exercise heart rate by multiplying it by 6.

Exercise heart rate: (10-sec pulse count) X 6 = bpm

2. Convert your walking time from minutes and seconds to a decimal figure. For example, a time of 14 minutes and 45 seconds would be 14 + (45/60), or 14.75 minutes.

Walking time: min + ( sec / 60 sec/min) = min

3. Insert values for your age, gender, weight, walking time, and exercise heart rate in the following equation, where:
W = your weight (in pounds)
A = your age (in years)
G = your gender (male 1; female 0)
T = your time to complete the 1-mile course (in minutes)
H = your exercise heart rate (in beats per minute)

VO2max = 132.853 - (0.0769 X W) - (0.3877 X A) + (6.315 X G) - (3.2649 X T) - (0.1565 X H)

For example, a 20-year-old, 190-pound male with a time of 14.75 minutes and an exercise heart rate of 152 bpm would calculate maximal oxygen consumption as follows:

VO2max = 132.853 - (0.0769 X 190) - (0.3877 X 20) + (6.315 X 1) - (3.2649 X 14.75) - (0.1565 X 152) = 45 ml/kg/min
VO2max = 132.853 - (0.0769 X (weight (lb))) - (0.3877 X (age (years))) + (6.315 X (gender)) - (3.2649 X (walking time (min))) - (0.1565 X (exercise heart rate (bpm))) = ml/kg/min

4. This value for VO2max has been copied into the appropriate place in the chart on the final page of this lab.

The 3-Minute Step Test

Equipment
1. A step, bench, or bleacher step that is 16.25 inches from ground level
2. A stopwatch, clock, or watch with a second hand
3. A metronome

Preparation

Practice stepping up onto and down from the step before you begin the test. Each step has four beats: up-up-down-down. Males should perform the test with the metronome set for a rate of 96 beats per minute, or 24 steps per minute. Females should set the metronome at 88 beats per minute, or 22 steps per minute.

Instructions
1. Warm up before taking the test. Do some walking, easy jogging, and stretching exercises.
2. Set the metronome at the proper rate. Your instructor or a partner can call out starting and stopping times; otherwise, have a clock or watch within easy viewing during the test.
3. Begin the test and continue to step at the correct pace for 3 minutes.
4. Stop after 3 minutes. Remain standing and count your pulse for the 15-second period from 5 to 20 seconds into recovery.

15-second pulse count: beats

5. Cool down after the test by walking slowly for several minutes.

Determining Maximal Oxygen Consumption

1. Convert your 15-second pulse count to a value for recovery heart rate by multiplying by 4.
2. Recovery heart rate: (15-sec pulse count) X 4 = bpm

3. Insert your recovery heart rate in the equation below, where

H = recovery heart rate (in beats per minute)

Males: VO2max = 111.33 - (0.42 X H)

Females: VO2max = 65.81 - (0.1847 X H)

For example, a man with a recovery heart rate of 162 bpm would calculate maximal oxygen consumption as follows:

VO2max = 111.33 - (0.42 X 162) = 43 ml/kg/min

Males: VO2max = 111.33 - (0.42 X (recovery heart rate (bpm))) = ml/kg/min

Females: VO2max = 65.81 - (0.1847 X (recovery heart rate (bpm))) = ml/kg/min

4. This value for VO2max has been copied into the appropriate place in the chart on the final page of this lab.

The 1.5-Mile Run-Walk Test

Equipment
A running track or course that is flat and provides exact measurements of up to 1.5 miles A stopwatch, clock, or watch with a second hand

Preparation
You may want to practice pacing yourself prior to taking the test to avoid going too fast at the start and becoming pre-maturely fatigued. Allow yourself a day or two to recover from your practice run before taking the test.

Instructions

1. Warm up before taking the test. Do some walking, easy jogging, and stretching exercises.
2. Try to cover the distance as fast as possible without overexerting yourself. If possible, monitor your own time, or have someone call out your time at various intervals of the test to determine whether your pace is correct.
3. Record the amount of time, in minutes and seconds, it takes you to complete the 1.5-mile distance.

Running-walking time: min sec *

4. Cool down after the test by walking or jogging slowly for about 5 minutes.

Determining Maximal Oxygen Consumption
1. Convert your running time from minutes and seconds to a decimal figure. For example, a time of 14 minutes and 25 seconds would be 14 + (25/60), or 14.4 minutes.

Running-walking time: min + ( sec / 60 sec/min) = min

2. Insert your running time in the equation below, where

T = running time (in minutes)

VO2max = (483 / T) + 3.5

For example, a person who completes 1.5 miles in 14.4 minutes would calculate maximal oxygen consumption as follows:

VO2max (483 / 14.4) + 3.5 = 37 ml/kg/min

VO2max = (483 / (run-walk time (min))) + 3.5 = ml/kg/min

3. This value for VO2max has been copied into the appropriate place in the chart on the final page of this lab.
