本文运用生物力学的研究方法,对出版发行的四种含有掩手肱捶动作的VCD光盘。运用播放、慢放和单步播放的方法。并结合笔者练习心得。从中研究出掩手肱捶动作的用力顺序、重心移动路线以及参与发力肌肉与关节部位。使复杂的动作简单化,为广大的练习者提供些学习方法和演练技巧。同时也为其它较复杂动作的学习提供些学习方法的参考。 In this paper, using biomechanical research methods, published on the publication of the four cover hand brachial hammer action VCD disc. Use play, slow play and single-step play method. Combined with the author practice experience. From which to study the force sequence to hide the hand-brachial hammer movement, the center of gravity to move the route and to participate in the development of muscle and joint parts. To simplify the complexity of the action for the majority of practitioners to provide some learning methods and exercises skills. At the same time, it also provides reference for other learning methods for other more complicated movements.
