对四川省武术队国家一级和武英级运动员旋风脚转体720°起跳阶段人体重心的运动学特征进行了对比分析。结果表明:助跑最后一步结束左脚着地时刻重心水平速度、缓冲时段重心水平速度的损失与右脚离地时刻垂直速度之间不存在相关关系;右脚离地时刻,重心水平速度的损失率与垂直速度之间为正相关。蹬伸时段重心水平位移与左脚离地时刻重心水平速度、重心垂直速度之间存在显著性相关;在缓冲时段一级运动员没有武英级身体重心低,用时长,然而蹬伸时间没有显著差异,这是一级运动员没有武英级完成动作好的根本所在。
The kinematics characteristics of the center of gravity of the body of a wushu team at the national level and the Wuyou class athletes at 720 ° take-off stage were analyzed. The results show that there is no correlation between the horizontal velocity of the center of gravity of the left foot and the vertical velocity of the right foot from the ground when the left foot approaches the end of the last step. The loss rate of the horizontal velocity of the right foot from the ground, There is a positive correlation between vertical velocities. There was a significant correlation between the horizontal center of gravity displacement and the center of gravity and the vertical velocity of the center of gravity of the left foot at the time of kicking stretching stage. There was no significant difference between the first and the second stage athletes in the buffering period, This is a level one athlete Wu Wu-class action to complete a good place.
