How long does the stepping phase last in the Queen's College Step Test?

• A. 1 minute
• B. 2 minutes
• C. 3 minutes
• D. 4 minutes

Answer: (C)

In this test, the stepping phase is designed to create a steady, submaximal cardiovascular load so you can estimate vo2 max from the body's recovery response. Three minutes is the chosen duration because it’s long enough for the heart rate to respond to the workload without pushing you into fatigue, which could distort the recovery heart-rate measurement used for the estimation. If the stepping were shorter, the heart rate might not reflect a stable submaximal effort; if longer, fatigue could elevate heart rate unrelated to aerobic fitness. Keeping it at three minutes provides a practical, accurate balance for predicting aerobic capacity from recovery data.
