技巧“手推抛后空翻360°旋下”的生物力学研究

Biomechanics Research on Double Salto Backwards by Hand Throwing in Acrobatics

以50幅/秒的频率拍摄我国优秀技巧女双运动员倪文秀、段可婕的技术,采用三推测力同步系统进行动力指标测试,将所得到的运动学、动力学图像参数对该动作进行定量的分析与研究,从而找出技术结构的规律,并提出进一步提高技术水平的措施。

Technical pictures of elite women pairs in acrobati(?)s in our country were taken in the frequency of 50 frames/second.A synchronized system of three dimenstonal power testing was used to test the dynamic indexes.Quantitative analysis andstudy of the double salto backwards movement was carried o(?) by using the kinematics and kinetics images parameter ac-quired from the test so that the law of technical structure of the movement was found and the measures to further improvethe technical level were put forward.
