What is a Chester Step Test?

The Chester Step Test is a submaximal exercise test used to assess aerobic fitness and estimate cardiovascular capacity.

You step on and off a standardised step in time with an increasing cadence while your heart rate and perceived exertion are monitored.

It is commonly used in occupational medical assessments where evidence of adequate aerobic fitness is required.

What happens during the test?

The test is progressive. The stepping rate increases at set intervals while your response to exercise is monitored.

The assessment is stopped when the required test endpoint is reached, or earlier if there is a clinical reason to stop.

The exercise component usually takes around 6–10 minutes, although additional time is allowed for preparation, baseline measurements and recovery.
