[Purpose] The purpose of this study was to compare the activity of the shoulder and trunk muscles in two push-up positions: standard push-ups and push-ups with the trunk flexed. [Subjects] Fifteen young adult males participated in the study. [Methods] This study measured the clavicular and sternocostal portions of the pectoralis major, the serratus anterior, and the rectus abdominis during push-ups under the two conditions. [Results] The activity of the sternocostal portion of the pectoralis major and that of the rectus abdominis were significantly greater under Condition 1 than under Condition 2. The activity of the clavicular portion of the pectoralis major and that of the serratus anterior were significantly greater under Condition 2 compared with Condition 1. [Conclusion] These results indicate that exercises can selectively activate muscle parts under different clinical situations.
[目的] 本研究的目的是比较两种俯卧撑姿势下肩部和躯干肌肉的活动情况：标准俯卧撑和躯干屈曲的俯卧撑。[受试者] 15名年轻成年男性参与了本研究。[方法] 本研究测量了在两种条件下做俯卧撑时胸大肌锁骨部和胸肋部、前锯肌以及腹直肌的情况。[结果] 条件1下胸大肌胸肋部和腹直肌的活动明显大于条件2。与条件1相比，条件2下胸大肌锁骨部和前锯肌的活动明显更大。[结论] 这些结果表明，运动可以在不同临床情况下选择性地激活肌肉部位。
