INTRODUCTION It is reported that the effects of three time periods of 5, 10, and 15 seconds (1) of maximum voluntary isometric contraction (MVIC) (2) in the slow-reversal-holdrelax stretching technique.
So, The purpose of this study was to investigative the effects of three time periods of 5, 10, and 15 seconds of maximum voluntary isometric contraction on hamstring flexibility in male non- athletes.
At the end of training period, rate of hamstring stretch was measured using SLR test.
Data were analyzed using dependent t-test and one-way ANOVA RESULTS It is observed that significant increases in hamstring flexibility for three groups."
