采用录像解析法和数理统计法,对第十一届全运会决赛3名优秀女子蹦床运动员决赛中屈体前空翻两周转体540°(晚转)动作进行运动学分析,结果表明:从离网瞬间到形成屈体动作瞬间,李丹表现最为突出,其技术特征是用时短、角度小、空翻周数大、水平位移小;黄珊汕开腿转体技术最出色,其特征是利用髋关节力量及手臂摆动在空翻阶段迅速完成转体,对身体的控制到位;钟杏平准备触网阶段的技术特点是直体腾空时间尽量长,使其有充分的时间准备触网。
The video analysis and mathematical statistics were used to analyze the kinematics of 540 ° (late turn) action of the former two turnaround bodies in the finals of the eleventh national women trampoline in the final of the 11th National Games. The results show that: The instantaneous moment of the formation of the ponching action, Li Dan, the most prominent performance, the technical characteristics of the time is short, the angle is small, the number of weeks flip, the horizontal displacement of small; Huang Shan Shan best leg rotation technology, which is characterized by the use of hip strength And arm swing quickly completed in the stage of turn over the turn of the body, the body’s control in place; Zhong Xingping phase of preparation for contact with the technical characteristics of the straight body as long as possible to make time, so that it has sufficient time to prepare for contact.
