The authors performed 3D photographic measurement on the technical moves of ZHANG Wen-xiu as an excellent female hammer thrower in China to get relatively comprehensive body movement data by using two JVC3000 high-speed cameras, screened and analyzed the data by using SPSS software, and revealed the following findings: in terms of such technical parameters as spinning time, spinning track and spinning speed, there were some problems with this player, which restricted the enhancement of her performance, such as the double leg supporting time was shorter than the single leg supporting time; the angle of inclination of the track of various swirls (espe-cially the first swirl) was somewhat too big; the accelerating process was too short; too much attention was paid to acceleration at the single leg supporting stage; the spinning at the double leg supporting stage was too fast; the sus-tainable accelerating power was not high.

摘 要:采用两台JVC3000高速摄像机对中国女子链球优秀运动员张文秀的技术动作进行三维摄影测量,获得较为全面的人体运动学数据;运用SPSS软件对数据进行筛选和相关分析,发现该运动员在旋转时间、轨迹和速度等技术参数方面存在着一些制约成绩提高的问题,诸如双支撑时间短于单支撑时间、各圈(尤其第1圈)的轨迹倾角偏大、加速过程太短、单支撑阶段过于强调加速及双支撑阶段旋转过快、持续加速能力不强等。
