肌电与足底压力同步测量在对我国优秀速滑运动员 蹬冰单步周期研究中的应用

目的:旨在建立肌电与足底压力同步模型,从身体内部工作状态的角度探讨速度滑冰的一般规律。方法:同步测量速滑运动肌电与足底压力以及视频信号,建立速度滑冰直道蹬冰单周期模型,揭示运动员身体内、外参数的变化规律。结果:建立了速滑蹬冰单周期模型,提出膝角120°位置处的爆发力为速滑的主要用力特征,将速滑蹬冰单周期细分为6个阶段。结论:肌电与足底压力同步测量、同步肌电分析方法的结合能有效地获取速滑运动身体信息和揭示运动规律,是一种有力的体育科学研究方法。

Application of EMG and Plantar Pressure in the Study of Measurement on Single Step Cycle of Elite Speed Skating Athletes

Purpose: The purpose of this research is to discuss speed skating disciplines from the viewpoint of body working states,by virtue of establishing EMG and plantar pressure synchronized model.Method: Measuring EMG and plantar pressure synchronal and establishing the model of speed skate single step.Results: Established speed skating single step model.The authors thought that the explosive contracting of lower limbs muscle at the position of 120o knee angle is the representational characteristic of speed skating.Compartmentalize speed skate single step to six phases.Conclusion: The method of EMG and plantar pressure synchronal measuring and analysis can get athletes body information and recovery sports disciplines effectively.It is a powerful method in the field of sports sciences research.
