# VO2 max Step Test

Testing and measurement are the means of collecting information upon which subsequent performance evaluations and decisions are made. In the analysis, we need to consider factors influencing the results.

### Objective

This test aims to monitor the development of the athlete's cardiovascular system.

### Required Resources

To conduct 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 evaluating 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 previous tests' results. It is expected that the analysis would indicate an improvement with appropriate training between each test.

#### 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 how a test is consistent and stable in measuring its intended 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 various factors influencing the results and test reliability.

#### Validity

This test provides a means to monitor training on the athlete's physical development. Test validity refers to the degree to which the test measures what it claims to measure and the extent to which inferences, conclusions, and decisions based on test scores are appropriate and meaningful.
