[Purpose] This study compared the activities of the abdominal and hip extensor muscles between the bridging exercise (BE) and bridging exercise with hip adduction (BEHA) positions in women using electromyography (EMG). [Subjects] We recruited 14 healthy adult females with no history of low back pain. [Methods] The subjects performed bridging exercises with and without hip adduction. The EMG activities of the rectus abdominis (RA), external oblique (EO), internal oblique (IO), and gluteus maximus (GM) muscles were recorded. [Result] The EMG activities of all muscles were significantly increased during the BEHA compared to the BE. [Conclusion] The bridging exercise with hip adduction produced greater activation of the abdominal and hip extensor muscles.
[目的] 本研究采用肌电图（EMG）比较了女性在桥式运动（BE）和髋关节内收桥式运动（BEHA）体位下腹部和髋部伸肌的活动情况。[对象] 我们招募了14名无腰痛病史的健康成年女性。[方法] 受试者进行了有无髋关节内收的桥式运动。记录腹直肌（RA）、腹外斜肌（EO）、腹内斜肌（IO）和臀大肌（GM）的肌电图活动。[结果] 与BE相比，BEHA期间所有肌肉的肌电图活动均显著增加。[结论] 髋关节内收的桥式运动能使腹部和髋部伸肌产生更大的激活。
