A short-term anaerobic test or power test in which the subject stands 2 m from a staircase and then sprints at top speed up the staircase, taking two steps at a time, each step being 175 mm high. Pressure pads on the eighth and twelfth step act as switches recording time taken to run between the pads. It is assumed that all the external work of the subject is used to raise the centre of mass of the body, and that this rise is the same as the vertical distance between the eighth and twelfth step. The power output (P) of the subject is calculated as follows: P = (W × 9.8 × D)/t, where W is the body weight of the subject in kilograms: 9.8 is the normal acceleration due to gravity in ms−2; D is the vertical height in metres between the eighth and twelfth steps: and t is the time taken from the first pressure pad to the second pad. This test is also known as the Margaria step test.
