Influence of limb length on a stepping exercise

Abstract

The effect of limb length on responses to the step-test exercise was studied in 10 subjects of various heights; oxygen consumption values served as an indicator. Mean oxygen consumption was found to be significantly related to limb length in the step-test exercise. This was demonstrated when subjects with different limb lengths were tested as a standard work load (i.e., 10 m/min x body wt) but at seven different bench heights and correspondingly adjusted stepping rates. The minimum values for oxygen consumption were obtained when the bench height was near 50% (45–55%) of subject's limb length.
