一、前言弧线助跑是背越式跳高的重要技术环节。合理正确的助跑弧线,不仅能最有效地发挥助跑速度,还可以利用适宜的跑速和身体内倾角度获得最佳的起跳效果,因此,对于背越式跳高弧线助跑的重要性,早在这种姿势刚被采用时,就被人们所重视,尽管当时助跑弧线的形式是多种多样的,但人们一致认为采用弧线助跑是背越式跳高能够取得成功的重要前提。到目前为止,背越式跳高助跑弧线的类型经过多年的实践和总结,已基本趋于一致,那种等半径弧或近于直线式以及全螺旋线式的助跑方法早已被淘汰,而代之于“J”型助跑弧线。人们一致认为 First, the foreword Arc is the back-style jump-style jump is an important technical link. Reasonable and correct arc of running can not only exert the running speed most effectively, but also can get the best take-off effect by using proper running speed and body inclination angle. Therefore, When this posture was adopted, it was valued by people. Although the shape of the running arc was varied at that time, it was agreed that using the arc to run was an important prerequisite for the success of the back-style jump. So far, the type of Fosbury Arc jump arc has been basically the same after many years of practice and conclusion, and the method of equi-radius arc or near-linear and full-helix run has already been eliminated, The “J” -type running arc. People agree
