一、选题依据“团身前空翻三周”,(以下简称“前三周”),是由中国运动员创造的技巧单人项目的高难动作,一九八六年被国际技联技术委员会确定为男单第一套最高难度的空翻动作之一。广东姚志华是目前世界上第一个试作该动作的女运动员,这无疑是我国女运动员赶超世界先进水平的开拓之举。本文运用运动生物力学的研究手段,对“前三周”动作的主要环节——起跳阶段的动作技术进行定量分析,找出符合生物力学规律的运动技术特征、探索相对合理的“前三周”起跳技术,为运动实践服务。
First, based on the theme of “three days before the group rollover” (hereinafter referred to as “the first three weeks”) is a tricky action by the Chinese athletes to create a single project, in 1986 by the International Technical Federation Technical Committee One of the toughest taps for men’s singles. Guangdong Yao Zhihua is currently the world’s first female athlete trying out the action, which is undoubtedly the pioneering move of our country’s female athletes to surpass the world’s advanced level. In this paper, we use the research methods of sports biomechanics to quantitatively analyze the movement technique in the take-off stage, which is the main link of “the first three weeks”, find out the technical characteristics of sports in line with the laws of biomechanics, and explore a relatively reasonable “first three weeks” Take-off techniques for sports practice services.
