速度轮滑双蹬技术足底压力分布及传递特征

为揭示速度轮滑双蹬技术的规律和特征,正确理解速度轮滑双蹬技术动作原理,为寻找更先进和省力的速度轮滑技术提供科学依据。运用足底压力分布测试系统,以专业轮滑运动员为研究对象,获取不同速度滑行过程运动员在双蹬技术一个单步中的足底动力学参数。结果说明足底压力随时间变化是影响速度轮滑蹬动效果的主要因素;不同的足底压力传递特征体现了不同的技术动作,从而形成不同的运动效果;在快速滑行中双蹬技术更有利于保持身体平衡。

Characteristics of the distribution and transmission of sole pressure when the twice-striding technique is applied for speed roller skating

In order to reveal the pattern and characteristics of the twice-striding technique for speed roller skating,to establish a foundation for correctly understanding the kinetic principle of the twice-striding technique for speed roller skating,and to provide a scientific criterion for seeking for a more advanced and effortless technique for speed roller skating,the author based his study subject on professional roller skating athletes to acquire the kinetic pa-rameters of the sole of the athletes in a single stride in the twice-striding technique in the process of skating at dif-ferent speeds,and drew the following conclusions: The variation of sole pressure with the time is the main factor that affects the striding effect of speed roller skating;different characteristics of the transmission of sole pressure represent different technical moves,thus producing different moving effects;in speed gliding the twice-striding technique is more conducive to maintaining body balance.
