摘要
本文采用平面定点定机摄像法对4名国际级乒乓球运动员的正手近远台攻球技术进行录像拍摄,采用美国APAS录像分析系统进行录像解析,获取近远台攻球技术动作各个阶段的定量运动学数据。结果表明:受试者远台击球时刻肘关节角度明显大于近台击球时肘关节角度;肘关节角速度的变化遵循慢——快——慢的节奏;在挥拍击球阶段远台攻球时肩关节角度明显大于近台;正手攻球过程中重心位移变化近台大于远台但重心移动速度远台大于近台。
The video was shot by using the camera method to designated forehand technology of four international grade of table tennis athletes, and video analysis using by the APAS sys- tem, getting the quantitative kinematic data close to hitting technology in every stage. The results show that ： elbow angle of participants in the distant table significantly greater than the elbow angle nearby the table ; The change of the elbow angular velocity follow slow - fast - slow rhythm; the angle of the shoulder significantly greater in the distant table than that of nearby table during the ball swing phase ; In the process of forehand attack nearby table , dis- placement variation of focus are more than that of distant table, but the speed of focus far greater than that ot nearby table.
