This study aimed to compare the effect of three stretching techniques (ballistic, static and contract-relax) on instant gain muscle flexibility on the hamstring muscle. We evaluated 23 subjects of both gender [means (SD) age 21.17 (1.4) years]. All volunteers performed static, ballistic and contract-relax stretching. Each technique was performed in a single session with an interval of seven days between sessions. To assess the immediate effects of the different techniques were performed two tests of flexibility, Sit and Reach Test and the Popliteal Angle Test. In comparison with the baseline there were significant increase in muscle flexibility in the Popliteal Angle Test after application ballistic (6.26%) and contract-relax technique (6.5%) respectively (p<0.05). When comparing the three techniques regarding the change score significant difference was found in the the Popliteal Angle Test for ballistic and contract-relax stretching, but Sit and Reach Test showed no significance difference. These data suggest that the ballistic and contract-relax were better than the technique of static stretching and both are equally effective. The ballistic contract-relax stretching techniques improved gain of muscle flexibility on the hamstring muscle.
