对我国女子标枪全国锦标赛前6名运动员助跑最后4步进行生物力学分析,结果表明,后4步助跑速度没有体现出应有的水平,原因可能有:自身的速度能力不足;专项能力欠缺,有意识地控制了助跑速度;运动员在倒数第2步时出现了相对明显的速度下降;应该强调踝、膝关节积极地向前摆动,达到加大肢体动作幅度的技术效果。李玲蔚比赛中所表现出的运动学参数,基本上代表了我国女子标枪优秀运动员的技术特征,体现着标枪技术合理的动作结构。
The results show that the speed of the last 4 steps did not reflect the proper level, which may be due to the lack of speed ability, the lack of special ability and the awareness of the special athletes Controlled the run-up speed; athletes in the penultimate step appeared relatively obvious speed drop; should emphasize the ankle, knee actively swing forward to achieve the effect of increasing limb movement range of the technical effect. The kinematics parameters exhibited by Li Lingwei basically represent the technical characteristics of Chinese elite javelin athletes and reflect the reasonable movement structure of javelin.
