背越式跳高快速弧线助跑起跳对起跳效果的影响

Take-off Effect Study of Fast Curved Fosbury Flop of High-Jump

为进一步研究背越式跳高起跳理论 ,运用文献资料法 ,对背越式跳高弧线助跑起跳过程进行分析 ,揭示弧线助跑起跳为背越式跳高身体重心运动方向和垂直速度的提早改变和累积创造了有利条件 ,身体由内倾转变为竖直过程 ,身体重心和垂直速度随之加速上升和增大 ,加快助跑速度有利于提高起跳效果。

The curved run take-off created efficient condition for the earlier charge and accumlation of gravity center and vertical speed of Fosbury Flop.During the process the moving direction of body turns from inward dedine to vertical position ,the body gravity center increaese on the contrary,and the vertical speed accelerates with the accelaration of the body gravity center.
