摘要：AbstractAim: The purpose of this study was to determine the effects of static stretching, dynamic stretching, and no stretching warm-up trials on 10-m acceleration, 20 – m maximal speed, and agility of elite male soccer players. Methods: The participants of this study were 20 elite male soccer players from a competitive high school soccer team (age=16-18).Results: The results of the repeated measures analysis of variance (ANOVA) determined that: 1- There were no significant differences among the different warm-up protocols for 10-m acceleration tests. 2- There were significant differences among the different warm-up protocols for the 20-m maximal speed and agility test, with dynamic stretching resulting in significantly better performance than static and no stretching.Conclusion: Therefor, the research conclude that warm-up protocols that consisted of dynamic exercise resulted in an overall performance enhancement, and static stretching resulted in a detriment performance.
