【摘要】：本文通过参考文献法、视频解析法、数理统计法等研究方法对我国男子跳高运动员张国伟与国外优秀男子跳高运动员在跳高比赛中的各项数据进行收集整理。从人体在运动中应当遵循的客观规律出发,构建出背越式跳高不同阶段身体应当出现的合理动作框架,并以此为基础将收集到的张国伟在助跑、起跳、过杆等阶段的数据与国外优秀运动员进行全面的横向对比,找出其在背越式跳高技术动作方面存在的不足。得出如下结论:1、我国男子跳高运动员张国伟在助跑阶段的速度已经达到世界优秀水平,但是速度损失率较大,助跑最后一步至起跳过程中身体内倾角度较小,以近似直线的跑动轨迹结束助跑不利于腾空后身体自然背对横杆。2、张国伟在起跳过程中,手臂和摆动腿的摆动速度较小,踝关节爆发力弱,起跳离地时摆动腿刻意向异侧肩方向摆动,没能最大限度地发挥起跳能力。3、在完成起跳动作后的腾空阶段,张国伟的摆动腿没有主动下放,造成过杆时期背弓幅度小,影响了过杆效率。
[Abstract]:This paper collects and collates the data of Chinese male high jumper Zhang Guowei and foreign excellent male high jumpers in the high jump competition by the methods of reference, video analysis, mathematical statistics and so on. Starting from the objective law that the human body should follow in sports, this paper constructs a reasonable frame of action that should appear in the body in different stages of the back jump, and on this basis, Zhang Guowei will collect the run-up and take off of Zhang Guowei. The data of cross pole and other stages are compared with the foreign elite athletes in order to find out their shortcomings in the technical movements of the back-type high jump. The conclusion is as follows: 1. Zhang Guowei, a Chinese male high jumper, has reached an excellent speed level in the run-up phase, but the speed loss rate is relatively high, and the inclination of the body during the last step of the run-up to the take-off process is relatively small. Ending the run-up with an approximate straight line is not conducive to the natural back-to-crossbar of the body after being vacated. Zhang Guowei, in the process of taking off, has a small swing speed of arms and swing legs, and a weak explosive force of the ankle joint. When taking off the ground, the swinging leg wobbled deliberately in the direction of the different shoulder and failed to maximize the ability of take-off. In the empty stage after the take-off, Zhang Guowei's swinging leg did not actively lower down, resulting in a small amplitude of the back bow during the period of the pole crossing. Affect the efficiency of the rod.
