摘要
运用三维摄像方法对我国6名优秀男子铁饼运动员(右手掷铁饼)的旋转技术进行研究,利用三维运动快速解析系统获取数据,分析获得旋转阶段各个环节与铁饼成绩相关密切的指标。分析认为:不同阶段的肩髋俯视角度与重心的移动速度能影响到铁饼旋转技术完成过程中的节奏、时间分配和爆发性。
It has made a discussion of the revolving technique of six elite men discus-throwing athletes（right-handed） applying three-dimensional shooting technique.It makes use of three-dimensional sports to analyze the system fast to get the statistics,which will be analyzed to obtain the norms closely related with the discus score in the revolving process of discus-throwing of elite men athletes.It was drawn a conclusion that the shoulder-hip cord angle and the movement rate of body centroidis at different phases will influence the rhythm,time-share and fulminating of rotating throwing discus technique.
