浅析身体重心与起跑器角度之间的关系

文章从人体预备姿势的重心位置出发，对怎样精确选取起跑器的角度进行了理论分析和实验；实验结果显示，在踝关节与起跑器的接触面达到最大屈角的情况下，起跑器角度的选择在重心位置与后蹬腿的发力作用线重合或者距离最小重合时，才能达到最佳。

Relation between the barycentre of body and block angle

The article sets out from the barycentre position where the human .body prepares the posture, analyses that chooses the angle of the block. The experimental result shows, in a situation that the contact surfaces of ankle joint and block reach and crook the angle the most largly, block angle choose position and back leg bare an effect function to be line coincident in barycentre or from minimum and coincident, could up to best.
