对助跑中的物理知识进行分析,选择直线和曲线组合的助跑路线(“J”形助跑路线)比单纯地选择直线助跑路线更优。对蹯跳中的物理知识进行分析,认为不仅起跳角度很重要,初速度的大小也一样重要,因为人的动能和速度平方成正比关系,所以为了人体获得比较大的动能就要有一定的速度。对腾空、转体和过杆中的物理知识进行分析,认为腾空后的运动员受到的外力只有重力的作用,然而通过肢体运动可以改变某一坐标轴的转动惯量,从而完成转体和过杆动作。
Analysis of the physical knowledge in the run, choose the combination of straight line and curve of the runway ( “J ” shaped runway) than simply choose a straight run route is better. The analysis of the physical knowledge in the jump jump, not only the angle of take-off is very important, the size of the initial velocity is also important, because the kinetic energy and the square of the speed is proportional to, so in order to get a larger body kinetic energy there must be a certain speed . The analysis of the physical knowledge of the vacated, swivel and over the pole that after the emptiness of the athletes subjected to external forces only the role of gravity, but through the limb movement can change the moment of inertia of a coordinate axis, in order to complete the swivel and over the bar action .
