速度滑冰与速度轮滑运动员入弯技术运动学特征比较研究

A Comparative Study on the Kinematic Characteristics of Curve Entry Technique between Speed Skater and Speed Roller Skater

本文对4名国家一级速度滑冰男运动员与4名国家一级速度轮滑男运动员在入弯阶段运动学特征进行比较,旨在探究速度滑冰与速度轮滑运动员入弯技术运动学的差异性。运用测试法、数理统计法等多种研究方法,通过三维摄像测试运动员滑行运动学参数,监测弯道入弯阶段时运动员的滑行时间、步长、重心速度、关节角度等运动学相关数据,找出两个项目运动员入弯技术的差异,并进行统计分析。

In this paper,the kinematic characteristics of four national level I male speed skaters and four national Level I male speed skaters in the turn stage were compared.The purpose of this paper is to explore the kinematic difference between speed skating and speed roller skating in entering the curve.Use various research methods,such as testing method,mathematical statistics,etc.,through 3D camera testing athletes'sliding kinematics parameters,monitor athletes'sliding time,step length,center of gravity speed,joint angle and other related data of kinematics data during the curve entry stage,find out the differences between the two events'athletes'curve entry technique,and conduct statistical analysis.
