采用三维运动学的研究方法,对我国优秀铁饼运动员宋爱民在训练和比赛中的实际试投技术环节的运动学特征进行分析。发现其在投掷过程中右脚落地后,转动不积极,左侧支撑较差,最后用力工作距离较短;从根本上找出了技术运用不合理的原因,从而加深对掷铁饼技术运用的理解。 Using the research method of three-dimensional kinematics, this paper analyzes the kinematics characteristics of the actual trial-and-error technical aspects of Chinese elite discus throwers in training and competition. Found that during the throwing process, the right foot landed, the rotation is not active, the left support is poor, the last hard working distance is short; fundamentally find out the reason for the use of technology is unreasonable, thus deepening the understanding of discus throwing technology .
