| 中文摘要: |
| 借助表面肌电图技术、三维高速摄像技术对高校优秀网球运动员双手反拍击球时躯干肌肉放电情况进行研究，运用生物力学理论分析得出：弧线式引拍方式有利于躯干的充分扭转，积累更多躯干的弹性势能,高校网球优秀选手躯干左右两侧旋转肌肉群收缩协调性较差。

| 英文摘要: |
| This research studies the discharging of trunk muscles in the two-handed backhand batting of elite college tennis players by surface EMG technique and three-dimensional high speed video. Biomechanical analysis shows that arc type backswing is beneficial to sufficient torso twist and accumulates more elastic potential energy. The contractive coordination of the left and right torso rotation muscles of the elite college tennis players is poor. |
