[Purpose] This study was conducted to investigate the immediate prophylactic effects of local vibration on quadriceps muscle fatigue in young non-athletic males. [Participants and Methods] Thirty healthy young males were randomly assigned to vibration and sham control groups. Participants in the local vibration group received a single session vibration (2 minutes, 30 Hz). They also in the control group received a 2-minute vibration, while the vibration system was off. MVC, RMS and median frequency of EMG findings and time to reach fatigue were measured. [Results] Time to reach fatigue and MVC in the local vibration group was significantly high than those in the sham control group. [Conclusion] It seems that the prior local muscle vibration may be useful to attenuate some signs and symptoms of muscle fatigue.
[目的] 本研究旨在探讨局部振动对年轻非运动员男性股四头肌疲劳的即时预防作用。[参与者与方法] 30名健康年轻男性被随机分为振动组和假对照组。局部振动组的参与者接受单次振动（2分钟，30Hz）。对照组的参与者也接受2分钟的振动，但振动系统关闭。测量肌电图结果的最大自主收缩（MVC）、均方根（RMS）和中位频率以及达到疲劳的时间。[结果] 局部振动组达到疲劳的时间和MVC显著高于假对照组。[结论] 似乎预先进行局部肌肉振动可能有助于减轻肌肉疲劳的一些体征和症状。
