The purpose of this study was to investigate the short-term effects of static stretching, with vibration given directly over Achilles tendon, on electro-myographic (EMG) responses and vertical jump (VJ) performances. Fifteen male, college athletes voluntarily participated in this study (n=15; age: 22±4 years old; body height: 181±10 cm; body mass: 74±11 kg). All stages were completed within 90 minutes for each participant. Tendon vibration bouts lasted 30 seconds at 50 Hz for each volunteer. EMG analysis for peripheral silent period, H-reflex, H-reflex threshold, T-reflex and H/M ratio were completed for each experimental phases. EMG data were obtained from the soleus muscle in response to electro stimulation on the popliteal post tibial nerve. As expected, the dynamic warm-up (DW) increased VJ performances (p=0.004). Increased VJ performances after the DW were not statistically substantiated by the EMG findings. In addition, EMG results did not indicate that either static stretching (SS) or tendon vibration combined with static stretching (TVSS) had any detrimental or facilitation effect on vertical jump performances. In conclusion, using TVSS does not seem to facilitate warm-up effects before explosive performance.
本研究旨在探究直接在跟腱上施加振动的静态拉伸对肌电图（EMG）反应和垂直跳跃（VJ）表现的短期影响。15 名男性大学生运动员自愿参与本研究（n=15；年龄：22±4 岁；身高：181±10cm；体重：74±11kg）。每位参与者在 90 分钟内完成所有阶段。每位志愿者的跟腱振动持续 30 秒，频率为 50Hz。针对外周静息期、H 反射、H 反射阈值、T 反射和 H/M 比，完成了 EMG 分析。通过对腓肠后胫神经进行电刺激，从比目鱼肌获得 EMG 数据。正如预期的那样，动态热身（DW）提高了 VJ 表现（p=0.004）。但 DW 后 VJ 表现的提高在 EMG 发现中没有得到统计学上的证实。此外，EMG 结果表明，无论是静态拉伸（SS）还是结合静态拉伸的跟腱振动（TVSS）都不会对垂直跳跃表现产生不利或促进作用。总之，在进行爆发性表现之前，使用 TVSS 似乎不会促进热身效果。
