Abstract

The problem of the study was to investigate the effect of physiological fatigue upon mechanical alterations in running. The investigation involved a biomedical analysis of kinematic parameters which compared running mechanics of subjects both fresh and fatigued.

The study revealed numerous alterations in running mechanics associated with fatigue. Maximum vertical displacement of the body's center of gravity was found during the toe-off phase and was significantly less during fatigue. Stride lengths were found to be as much as 2.72 feet shorter during fatigue and stride times as great as .42 seconds shorter. Extension of the support leg was less and flexion was markedly changed during fatigue. Lastly, non-support times were determined to be less, and support times were greater during fatigue.
