采用人体三维转动研究的新方法分析跳马侧手翻直体侧空翻转体990°技术动作

Kinematic Analysis of the Tsuhakara 3/1 Horse Vaulting by the Study Method of Human Body 3D Rotation

采用人体三维转动新的运动学指标和方法—卡尔丹角及绝对角速度对江苏队健将级运动员吕军海跳马侧手翻直体侧空翻转体990°高难技术动作进行了全过程测试分析,给出了完整的人体侧翻、空翻、转体三维转动数据,揭示了该高难动作技术三维转动规律以及侧翻、空翻、转体技术特征,为我国运动员发展和改进此类动作技术提供了全新的理论和实践上的参考依据。

By using Cardanic angle and absolute angular velocity, the authors analyzed the Tsuhakara 3/ 1 of the horse vaulting of Lu Junhai, one of the top gymnasts in Jiangsu Province. The article provides the full 3D rotation data of sideflip, somersault ＆ twist. It reveals the 3D rotation law of this high-difficult movement and the technical characteristics of sideflip, somersault ＆ twist. It aims to offer a brand new theoretical and practical reference basis for developing and improving this kind of movements.
