Methods： Seventy-four male collegiate soccer players took part in the study and were randomly assigned to FIFA 11＋ with acute vibration group （FIFA ＋ WBV）, FIFA 11＋ with isometric squat group （FIFA ＋ IS） or a control group consisting of the F1FA 11＋ alone （Con）. The warm-up consisted of the FIFA 11＋ and was administered to all participants. The participants in the acute vibration group were exposed to 30 s whole body vibration in squat position immediately post warm-up. The isometric group completed an isometric squat for 30 s immediately post warm-up. Results： RSI significantly improved pre- to post-intervention amongst FIFA ＋ WBV （p 〈 0.001） due to a decrease in contact time （p 〈 0.001） in comparison to FIFA ＋ IS and Con, but 505 agility was not affected. Conclusion： The results of this study suggest the inclusion of an acute bout of WBV post FIFA 11＋ warm-up produces a neuromuscular response leading to an improvement in RSI. Future research is required to examine the exact mechanisms behind these improvements amongst other populations and over time course of the performance.展开更多
