| 摘 要： | 通过对单板U型场地滑雪项目比赛中运动员技术动作分析后发现,空翻与转体是整套动作的难度核心。为更好地了解空翻与转体动作的特性,主要运用运动生物力学基础理论和现场观察、文献资料等方法,对空翻和转体动作进行生物力学分析。结果表明：人体的转动轴、翻转的时空特征、翻转的角速度变化、人体转动惯量以及运动员身体形态、腾空姿态等因素均对空翻与转体动作产生影响。为此建议运动员提高翻转时对高度、速率和角度的控制,不断提高技术难度。

| Abstract: | After analyzing the snowboarders' technical motion in half-pipe snowboarding competition,the article finds out that the flip and turn motion are the core of total motion difficulty. In order to better understand the characteristics of flip and turn motion,with the methods of biomechanical theory,on-site observation and documentary information,it has a biomechanical analysis on the flip and turn motion. The results show that the influencing factors on the flip and turn motion relate to the change of turn axi... |
