Eighteen healthy males (aged 19-37 years) were placed in a standardized position. Knee flexion range of motion (ROM) measurements were recorded following ten 15-second passive stretch repetitions. Analysis of variance measures (p<0.05) and post hoc analysis showed that significant increases in knee extension ROM diminished at the fifth stretch repetition. The greatest single increase in knee extension ROM occurred after the first stretch. The results of this study indicate that passive stretching beyond five repetitions results in insignificant gains in hamstring length (measured via knee extension ROM) and are probably unnecessary. | | Language | eng | | Pub Type(s) | Journal Article
