      摘 要:目的:通过三维运动学仪器分析咏春拳日字冲拳肩髋转动的特点,并探讨咏春拳的发力特征,为咏春拳技术要领科学化阐释及其训练提供建议。方法:受试者为5名咏春拳教练,运用VICON三维运动学仪器采集日字冲拳过程的运动学数据。结果:肩髋转动角变化突然但幅度小;从位移变化看两肩有小幅对拉以助发力;髋关节转动幅度小,髋关节水平转动呈现转动圆心在髋关节中点和偏向对侧髋点两种方式,高水平教练使用的是后一种发力方式。结论:1)咏春拳日字冲拳肩髋转动角度小,没有明显预摆动作,易于突然进攻以及变换动作。2)日字冲拳髋关节水平转动圆心偏向对侧髋点形成的转动力矩较大,增强了在二字钳羊马姿势下的发力效果。

      Abstract:Objectives: By using three-dimensional kinematics instrument to analyze the characteristic of the rotation of shoulder and hip in Wing Chun Rizi punching, this paper aims to provide advice for the scientific explanation and training of the key Wing Chun techniques and to discuss its punching features. Methods: With five male Wing Chun coaches as subjects, VICON three-dimensional kinematics instrument was used to gather the kinematics statistics during kinematics. Results: The variation of rotation angle of shoulder and hip is small but sudden; two shoulders point displacement variation displays a slight opposite pull to facilitate power generating; amplitude of hip rotation is small and the horizontal rotation of hip shows that the rotation center is either in hip midpoint or tend to lateral hip point. High-level coaches use the latter one to generate strength. Conclusions: 1) Rotation angle of shoulder and hip in Wing Chun Rizi punching presents small without obvious pre-swing action, which facilitates sudden attack and shift of action. 2) It is the horizontal rotation tendency of hip in Rizi punching that forms a bigger rotational torque, enhancing the force efficiency of in the Erzi Qian stance.
