Abstract:	Purpose: This study is to explore how different durations of static stretching used as warm-ups manner will affect the explosive force of legs. Method: There are 20 healthy college students in the experiments (14 males and 6 females) and they participated in four different manipulations. The data were collected after each stretching strategies, included non-stretching, and stretching for 15s, 30s and 60s respectively. The protocol was based on repeated measures and the principle of balance of the order and every subject was required to stand on one foot at a time, with one hand drawing the ipsilateral leg closer to the buttocks with maximal voluntary efforts. Either foot stretching exercise had to meet the time requirement. Then the subjects were measured by means of standing long jump and CMJ on Newtest force plate. The data were analyzed by repeated one-way ANOVA and LSD post hoc test. Results: Significant differences were observed on standing long jump and CMJ (p ＜ .05) and they show that static stretches for 15s and 30s had advantage over those for 0 second and 60 seconds. As the results suggested, different durations of stretching exercise would bring about different performances and the order from the best to the worse was 30s, 15s, non-stretching, and 60s. Conclusion: The study divulges the fact that doing immediate static stretching before exercise would not cause a negative influence on explosive performance, but there is a time domain adaptation. And then, the better choice for stretching duration is either ISs or 30s and 60s stretching is harmful for sport performance
