【摘要】：以我国优秀女子铅球运动员巩立姣推铅球为研究对象,主要运用专家访谈、录像拍摄和视频解析等生物力学测试法等对巩立姣技术进行运动学分析研究。研究表明:相比于2009年第11届全运会,巩立姣在2015年济南大奖赛时后摆、滑步和转换阶段"人-球"系统稳定性提高,躯干下压幅度增大,保持躯干下压能力提高,但滑步距离偏短;巩立姣投掷总时间延长,最后用力单支撑阶段时间得到延长;铅球滑步起投速度得到提高,铅球出手速度不足,最后用力双支用力能力提高,铅球加速技术得到改进,铅球出手角度加大,出手角度还是偏小。巩立姣最后用力阶段左侧支撑不积极,右侧髋部动作速度慢,影响了最后用力效果。
[Abstract]:Taking Gong Lijiao, an outstanding female shot put player in China, as the research object, the author mainly uses expert interviews. The kinematics analysis of Gong Lijiao technology was carried out by using biomechanical testing methods such as video recording and video analysis. The results showed that: compared with the 11th National Games in 2009. In 2015, Gong Lijiao swung back in Jinan Grand Prix. The stability of the "man-ball" system was improved in the sliding and transition stages, the amplitude of trunk pressure was increased, and the ability to maintain the downward pressure of trunk was improved, but the distance of sliding step was short. The total time of Gong Lijiao throwing was prolonged, and the time of single support stage was prolonged. The speed of shot slide is improved, the speed of shot put is insufficient, the ability of double force is improved, the accelerating technique of shot is improved, and the angle of shot put is increased. The angle of release is still small. The left side support is not active and the right hip movement speed is slow, which affects the final exertion effect.
