摘　　要：通过文献资料调研、视频观察和运动学研究方法揭示了我国优秀运动员滕海滨完成双杠屈体后空翻2周下的技术特点及运动学规律,从支撑摆动、腾空屈体2周和落地3个阶段剖析了它们之间的因果关系和技术细节。研究结果显示,支撑摆动推离杠的时机和方向、身体重心抛物线腾起的角度和速度、腾空的高度和向后屈体2周的翻转速度以及落地前伸髋的幅度和落地时的缓冲动作是完成好该动作的关键技术环节。Through using the method of literature review, video observation and kinematics anal ysis, this paper mainly reveals technical characteristics and kinematics laws of TENG Hal-bin~ s bent backflip 2 parallel bars and analyzes the causal relationship and the technical details a- mong the three stages of support-and swing, vacated flip 2 and landing. The result shows that the key technical aspects of the action is the timing and direction of pushing off the bar after support and-swing, the angle and speed of the parabolic of body center, the jumping height, the speed of back flip 2, the extent of reaching hip joint before landing and the amortizing action at the same time of landing.
