Effects of Exercise on Hip Range of Motion, Trunk Muscle Performance, and Gait Economy

Abstract

The results suggest that (1) six treatment sessions of passive stretching were sufficient to improve hip extension ROM; (2) 3 weeks of exercises performed daily improved trunk flexor muscle performance; and (3) training of isolated tasks, such as hip flexibility or trunk strengthening activities, did not produce the desired outcome in the economy of walking or running. Possible reasons for the results are discussed.
