Development of swim-start technique on starting block with a back plate.

通过前腿、后腿和手的运动分析和力测量，研究了在带后板的起跑块上的游泳起跑动作。成年男子竞技游泳运动员参与本研究。本研究的结果如下：后腿对水平起飞速度和头沉力矩的产生有贡献，前腿对重力的产生有反作用力，手对水平速度和头沉力矩的直接贡献较小。

A swimming start motion on a starting block with a back plate was investigated by motion analysis and force measurements of front-leg, rear-leg and hands. Adult male competitive swimmers participated in this study. The findings based on this study were as follows ; Rear-legs contributes the generation of horizontal take-off velocity and head-sinking moment, front-legs force generation acts against gravity and the direct contributions of horizontal velocity and head-sinking moment by hands are small.
