背越式跳高摆腿对起跳的影响
摘要

本文通过文献资料法、逻辑分析法和学生的学习实践过程中调查总结出,在跳高起跳过程中摆动腿的积极上摆对跳高起跳具有重要作用,积极有力的上摆有助于身体重心从水平移动顺利的转变到快速垂直上升，同时摆动腿的摆动幅度和摆动速度也具有重要意义,积极快速的上摆还能加快身体重心的上升速度提高跳高成绩。揭示了在起跳过程中摆动腿的摆动动作对身体重心的运动状况具有重要的影响。并在教学训练中严格把握摆腿教学。
关键词：背越式跳高 、摆动腿、起跳。
Abstract this article through the literature material law, the logical analytic method and in student's study practice process investigates summarizes, takes off in the process in the high jump to swing the leg on positively to suspend to the high jump takes off has the vital role, the positive powerful on pendulum is helpful to the bodily center of gravity from the level migration smooth transformation to the fast vertical rise, simultaneously swings the leg arc of oscillation and the swinging speed also has the vital significance, positive fast on suspends also can speed up the bodily center of gravity the ascending velocity to enhance the high jump result.Promulgated in has taken off in the process to swing the leg swinging movement to have the important influence to the bodily center of gravity movement condition.And the strict assurance suspends the leg teaching in the teaching training. 
Key word: The back more -like high jump, the swinging leg, take off.
