正手弧圈球技术的脚部用力研究

A Study of the Techniques of Forehand Loop Drive with the Foot Force

目的对乒乓球运动员正手弧圈球技术的脚部用力情况进行研究。方法首先要求运动员发出的正手弧圈球力量能够明显区分,分为强力量和中等力量两种;其次从3个方向(垂直、水平、前后)对两种发球力量进行测量;最后分别对左右脚发力进行生物力学分析,并对两脚发力最大值进行对比。结果不管是用中等力量或强力量完成正手弧圈球,垂直方向的下肢脚部用力均大于左右和前后方向的脚部用力,且身体重心的转移将密切影响脚部用力的大小。结论运动员在发出正手弧圈球时,不仅要十分注意前后方向和左右方向的脚部用力,同时还应调整身体的重心。

This paper makes a study of the techniques of forehand loop drive with the force on the players＇feet. The result shows that the forehand looper should not only pay much attention to their foot force in different directions, but also alter their center of gravity accordingly. ：
