| 摘 要： | 采用视频动作解析法,研究重剑运动员在不同速度、不同情境下弓步刺动作肘膝关节角度变化的运动学特征.结果显示:不同速度要求下,重剑运动员弓步刺动作协调性存在非线性动力学特征;不同情境下,重剑运动员弓步刺动作协调性可能存在非线性动力学特征;高、低水平重剑运动员在平时训练时的弓步刺动作协调模式相似;比赛情境时,高水平重剑运动员的弓步刺动作协调性显著好于低水平重剑运动员.

| Abstract: | Using the method of kinematics image analysis,the present paper investigated the kinematic features of the epee fencers' elbow and knee joint angle changes in lunge actions at different speeds and under different circumstances.It concluded that in different speeds,the lunge action coordination of epee fencers demonstrate nonlinear dynamic features;in different circumstances,the lunge action coordination of epee fencers may show nonlinear dynamic features;the high and low level epee fencers show similar lung... |
