采用4台数码摄像机对10名山东省男子跆拳道运动员横踢动作进行同步拍摄,并用德国SIMI motion录像解析系统对测试结果进行三维图像解析,旨在揭示男子跆拳道运动员横踢技术特点,以及髋、膝、踝等各个关节、角度运动学特征。结果显示：1）男子运动员在横踢动作中,提膝转髋、踢击、收腿三个阶段所占时间比例分别为35%、20%、45%。2）在横踢过程中运动员Z轴重心位移起伏较大,数值升高变化特征明显,可有效提高踢击效果。3）在横踢动作中,未发现跆拳道运动员的左支撑脚内旋达180°。4）跆拳道运动员左支撑腿位置并非是固定不变的,而是根据踢击目标的需要,不断调节支撑脚的滑动位置。

By using four digital cameras to catch the horizontal-kicking actions of ten Shandong Taekwondo male players in simultaneous video and using video analytic system of German SIMI motion to analyze the test results in three dimensional image,this article wants to show the technical characteristics of Taekwondo male players and variation of articulation or angles of hip,knee and ankle.The results show 1） The players＇ starting speeds have obvious advantage in controlling time of horizontal-kicking.At three stages of hip and knee turn,kicking and recovery of legs,the time scale are 35%,20% and 45%.2） In the z-axis,the increasing number of players＇ displacement of center of gravity is obvious.Lastly,3） we don＇t find the player＇s left foot pronation reach 1800 in horizontal-kicking actions.4）The position of the Taekwondo sportsman＇left support leg is not fixed.According to the kick aim,the position of support leg is constantly adjustive.
