运用两块瑞士产KISTLER三维测力台对10名优秀男乒乓球运动员正手拉弧圈球技术过程中地面对人体的地面支撑反作用力进行测试。用两种发力方式拉弧圈球，一为用最大力量，二为中等力量。从垂直、水平、前后3个方向对完成轻拉和重拉时左右脚地面支撑反作用力的生物力学特征进行了描述，并对两种技术动作之间左右脚支反力的最大力值进行了对比分析，得出：（1）完成轻拉和重拉时，垂直方向上的地面支撑反作用力最大，左右和前后方向上的支反力较小；身体重心的移动影响地面支撑反作用力的变化，两者之间有密切联系。（2）发力拉弧圈球时，更要注重增加左右方向和前后方向上的蹬地力和重心移动幅度。

The subjects were 10 excellent male table tennis players （20±2 years old, the training years were 11±2）. Two styles of loop drive techniques were tested, using the measurement of the KISTLER force-plate system （two force-plates were used）. One style of loop drive technique used medium strength, and the other used the biggest strength. The two styles of GRF data （peak and valley value of the vertical direction, left-right direction and the front-back direction） were analyzed and compared. The table tennis player＇s drive technique characteristic in three dimensions was described by the obtained dynamic data. When the player drive loop with the biggest strength, it paid more attention to increase the GRF of left-right direction and front-back direction, which mean that the moving of gravity in left-right direction and front-back direction should be increased.
