STRETCHING NO MORE EFFECTIVE THAN ECCENTRIC TRAINING FOR HAMSTRING ROM
Nelson, R. T., & Bandy, W. D. (2004). Eccentric training and static stretching improve hamstring flexibility of high school males. Journal of Athletic Training, 39, 254-258.P>
This study determined if the flexibility of high-school-aged males would improve after a 6-week eccentric exercise program. In addition, the changes in hamstring flexibility that occurred after the eccentric program were compared with a 6-week program of static stretching and with a control group of no stretching. Ss (N = 69) were assigned randomly to one of three groups: eccentric training, static stretching, or control. Hamstring flexibility was measured using the passive 90/90 test before and after the 6-week program.
Both experimental groups improved similarly (~+12°) and were significantly different to the control group (+1.67°).
Implication. Eccentric and static stretching training improved hamstring flexibility similarly over a 6-week period.
