BACKGROUND: Local vibration (LV) used as part of the warm-up can stimulate a specific body part and muscle group, potentially increasing muscle flexibility and performance. However, the effect of its combination with static stretching (SS) has not been thoroughly examined. OBJECTIVE: To elucidate the acute effectiveness of combining LV and SS (V+S) on the ROM of ankle dorsiflexion, squat jump, counter-movement jump (CMJ) and the dynamic postural stability index (DPSI). METHODS: Fifteen healthy men who were regularly involved in recreational sports participated in this study. Static Stretching, V+S, and non-stretching condition (control) were assigned randomly and the intervention period for each condition was five minutes. RESULTS: The dorsiflexion improved significantly in SS and V+S compared to the control. The CMJ height decreased significantly following SS compared to V+S and control. CONCLUSIONS: This study suggests that V+S improves ankle dorsiflexion ROM without compromising jump performance. Local vibration device could be an effective element in warming up but further research is warranted.

局部振动拉伸对着陆后脚踝运动范围，垂直跳跃性能和动态平衡的急性影响

背景：作为预热的一部分的局部振动（LV）可以刺激特定的身体部位和肌肉群，从而潜在地增加肌肉的柔韧性和性能。但是，尚未与静态拉伸（SS）结合使用的效果得到彻底检查。目的：阐明LV和SS（V + S）联合应用对踝背屈，下蹲跳，反运动跳（CMJ）和动态姿势稳定性指数（DPSI）ROM的急性有效性。方法：十五名定期参加休闲运动的健康男性参加了这项研究。随机分配静态拉伸，V + S和非拉伸条件（对照），每种条件的干预时间为五分钟。结果：与对照组相比，SS和V + S背屈明显改善。与V + S和对照组相比，SS后CMJ高度显着下降。结论：这项研究表明V + S改善脚踝背屈ROM而不会影响跳跃性能。局部振动装置可能是预热的有效元素，但有必要进行进一步的研究。
