起跳是背越式跳高技术中的关键环节,它起着衔接助跑和腾越横杆的作用,助跑阶段运动员所获得的水平速度通过起跳转化成为跳高需要的垂直速度,而且背越技术所持有的转体动量矩和旋转过杆动量矩也皆由起跳动作而转换。众所周知,起跳是背越式跳高技术中的关键环节,它起着衔接助跑和腾越横杆的作用,助跑阶段运动员所获得的水平速度通过起跳转化成为跳高需要的垂直速度,而且背越技术所持有的转体动量矩和旋转过杆动量矩也皆由起
Take-off is the key part of the back-style high jump technique. It plays the role of leading the run and leaping over the horizontal bar. The horizontal speed obtained by the athlete in the run-up phase transforms into the vertical speed required for the jump by taking-off, Some of the moment of rotation and moment of rotation of the lever are also converted by the take-off action. As we all know, take-off is a key part of the back-style high jump technique. It plays the role of leading and traversing the horizontal bar. The horizontal speed obtained by the athletes in the run-up phase translates into the vertical speed required for the jump by jumping off, Holds the moment of rotation and rotating lever moment of momentum are also from
