[Purpose] The purpose of this study was to investigate the changes of muscle activity during squat motion after stretching the tensor fasciae latae muscle. [Participants and Methods] The participants comprised 19 healthy males. The test muscles were the vastus medialis obliquus and vastus lateralis. The participants performed the squat motion before and after stretching the tensor fasciae latae. We measured the muscle activities and the onset timing of the vastus medialis obliquus relative to that of the vastus lateralis during squat motions. [Results] The onset timing of the vastus medialis obliquus relative to that of the vastus lateralis was decreased, and the vastus medialis obliquus activity and vastus medialis obliquus/vastus lateralis activity ratio were increased after stretching the tensor fasciae latae. [Conclusion] This study revealed that stretching of the tensor fasciae latae increases the relative vastus medialis obliquus muscle activity.
[目的]本研究旨在探讨阔筋膜张肌拉伸后深蹲运动过程中肌肉活动的变化。[参与者与方法]参与者包括19名健康男性。测试肌肉为股内侧斜肌和股外侧肌。参与者在阔筋膜张肌拉伸前后进行深蹲运动。我们测量了深蹲运动过程中股内侧斜肌相对于股外侧肌的肌肉活动及起始时间。[结果]阔筋膜张肌拉伸后，股内侧斜肌相对于股外侧肌的起始时间缩短，股内侧斜肌活动及股内侧斜肌/股外侧肌活动比值增加。[结论]本研究表明，阔筋膜张肌拉伸可增加股内侧斜肌的相对肌肉活动。
