双杠后摆上是各等级体操运动员所必须掌握的一个最基本的挂臂撑后摆动作。本文是从生物力学的观点对该动作各阶段的动力学和运动学特征做了比较详细的定性、定量分析,深入地阐述了动作的技术原理,并在理论上提出了一些新的观点。在综合分析的基础上,结合体操教学和训练实践,提出了合理、有效的教法建议。这些将对提高和改进该类动作的教学和训练工作起促进作用。 Parallel bars put on the rear of each level of gymnast must master a basic suspension arm movements. This article is from the biomechanical point of view of the kinematics and kinematics at various stages of the action made a more detailed qualitative and quantitative analysis of the technical principles of action in-depth, and put forward some new ideas in theory. On the basis of comprehensive analysis, combined with gymnastics teaching and training practice, put forward reasonable and effective teaching suggestions. These will contribute to teaching and training to improve and improve such actions.
