# VO2 max Step Test

Testing and measurement are the means of collecting information upon which subsequent performance evaluations and decisions are made but, in the analysis, we need to bear in mind the factors that may influence the results.

### Objective

The objective of this test is to monitor the development of the athlete's cardiovascular system.

### Required Resources

To undertake this test, you will require:

• A 16¼ inch high bench or step
• Stopwatch
• Heart rate monitor (optional)
• An assistant

### How to conduct the test

The VO2 max Step Test is conducted as follows:

 Step up and down, one foot at a time, onto the step or bench for 3 minutes Maintain a steady four-beat cycle Women 22 steps/minute Men 24 steps/minute On finishing the test count the number of heartbeats for 15 seconds Multiply the number of beats in 15 seconds by 4 to give the "step test pulse rate" Use this final value to assess the athlete's VO2 max using the calculator below

### Assessment

I am unable to locate any normative data for this test.

The following equations can be used to determine the athlete's VO2 max (McArdle 2000)[1]

• Men = 111.33 - (0.42 x pulse rate beats/min)
• Women = 65.81 - (0.1847 x pulse rate beats/min)

For an evaluation of the athlete's VO2 max select the gender, enter the "step test pulse rate" and then select the 'Calculate' button.

 Gender Female Male Step test pulse rate b.p.m. VO2 max - mL.kg.min

### Analysis

Analysis of the result is by comparing it with the results of previous tests. It is expected that, with appropriate training between each test, the analysis would indicate an improvement.

#### Target Group

This test is suitable for active and sedentary athletes but not for individuals where the test would be contraindicated.

#### Reliability

Test reliability refers to the degree to which a test is consistent and stable in measuring what it is intended to measure. Reliability will depend upon how strict the test is conducted and the individual's level of motivation to perform the test. The following link provides a variety of factors that may influence the results and therefore the test reliability.

#### Validity

Test validity refers to the degree to which the test actually measures what it claims to measure and the extent to which inferences, conclusions, and decisions made on the basis of test scores are appropriate and meaningful. This test provides a means to monitor the effect of training on the athlete's physical development. For an assessment of your VO2 max see the VO2 max normative data tables.

• Minimal equipment required
• Simple to set up and conduct
• Can be conducted almost anywhere

• Assistant required to administer the test
