一、引言 运动员在进行跳高时,不能也决不可能在横杆垂面内垂直起跳后越杆。故起跳瞬时重心轨迹方向与水平面之间必然存在一个夹角θ,这个角度就为腾起角,腾起角掌握得合理与否,将直接影响到训练素质和运动技能的正常发挥。因此,运动员要想取得比较理想的成绩,除了刻苦训练掌握好起跳和过杆的技术要领外,还必须对跳高腾起角度问题有个基本的了解。 I. INTRODUCTION Athletes can not and can not over-rod vertically after jumping in vertical plane. Therefore, there is an angle θ between the direction of the instantaneous center of gravity and the horizontal plane. This angle is a reasonable angle for the starting angle and the starting angle, which will directly affect the normal performance of training quality and motor skills. Therefore, athletes in order to achieve the desired result, in addition to hard training to master the technical essentials take-off and over the pole, but also must have a basic understanding of the issue of high jump.
