单板U型场地滑雪吊旋杠杆式旋转训练器的研制

Development of a Rotation Training Appliance with Lifting Lever Type for Half-pipe Snowboarders' Spin Abilityh

单板U型场地滑雪竞技运动过程中,空中旋转的周数和难度是最重要的技术环节和获得分数值高低的标志。我国单板U型场地滑雪运动员陆地空中旋转训练的辅助器材较少,缺乏陆地空中旋转多样化、系统化和专项化的训练手段,能使单板U型场地滑雪运动员达到陆地空中大幅度、多维旋转的训练器械处于空白状态。从技术的生物力学原理与运动员技能的形成机制出发,研制单板U型场地滑雪吊旋杠杆式旋转训练器,论述设计的基本要求与结构特征,以及工作原理与使用方法。

In the competition of half - pipe snowboarding, the revolution and difficulty of snowboarders＇ aerial spin are the most important technical part and a sign of high or low scoring. The land training aids are less for Chinese half- pipe snowboarders＇ aerial spin ability, and the land training means of aerial rotation are lacking in diversification, systematization and specialization. Especially, the land training appliance development for their having large range and multidimensional aerial rotation is nothing. Starting with the technical biomechanics principle and the snowboarders＇ skill development mechanism, the paper discusses a rotation training appliance with lifting lever type for half - pipe snowboarders＇ spin ability, and its basic requirements, architectural feature, running principle and usage.
