[Purpose] This study evaluated the effects of bridge exercise on trunk core muscle activity with respect to sling height and hip joint abduction and adduction. [Subjects] Fifteen healthy adult males participated. [Methods] In the bridge exercise, the height of the sling was set low or high during hip joint abduction and adduction. Electromyography was used to compare the differences between the muscle activities of the transverse abdominis, rectus abdominis, and erector spinae muscles. [Results] The muscle activities of the transverse abdominis, rectus abdominis, and erector spinae were significantly higher in the high sling position. Furthermore, the activities of the transverse abdominis and erector spinae were significantly higher during hip joint adduction than abduction regardless of sling height. [Conclusion] A high sling height is the most effective intervention for increasing the muscle activities of the transverse abdominis and erector spinae muscles during hip joint adduction in a bridge exercise.
[目的]本研究评估了桥式运动中吊带高度以及髋关节外展和内收对躯干核心肌肉活动的影响。[对象]15名健康成年男性参与了研究。[方法]在桥式运动中，髋关节外展和内收时将吊带高度设置为低或高。使用肌电图比较腹横肌、腹直肌和竖脊肌的肌肉活动差异。[结果]在高吊带位置时，腹横肌、腹直肌和竖脊肌的肌肉活动显著更高。此外，无论吊带高度如何，髋关节内收时腹横肌和竖脊肌的活动均显著高于外展时。[结论]在桥式运动中，高吊带高度是增加髋关节内收时腹横肌和竖脊肌肌肉活动的最有效干预措施。
