[Purpose] This study investigated the effects of the bridging plus exercise with heel lift on lower extremity muscles. [Subjects and Methods] Nine healthy males participated. The subjects performed bridging exercises under two conditions. Surface electromyography was used to measure the electrical activities of the medial hamstring (MH) and the gluteus maximus (GM) muscles. [Results] Activation of the MH muscle during bridging with heel lift decreased, and activation of the GM muscle during bridging with heel lift increased compared to those with the bridging exercise. [Conclusion] This result showed that bridging plus exercises with heel lift could be an effective exercise for patients with compensatory mechanisms during bridging exercises, such as weak GM with hamstring tightness.
[目的] 本研究调查了足跟抬起的桥式运动加锻炼对下肢肌肉的影响。[对象与方法] 九名健康男性参与。受试者在两种条件下进行桥式运动。使用表面肌电图测量半腱肌内侧（MH）和臀大肌（GM）的电活动。[结果] 与单纯桥式运动相比，足跟抬起的桥式运动过程中MH肌肉的激活减少，而足跟抬起的桥式运动过程中GM肌肉的激活增加。[结论] 该结果表明，对于在桥式运动中有代偿机制的患者，如臀大肌薄弱且绳肌紧张，足跟抬起的桥式运动加锻炼可能是一种有效的锻炼方式。
