摘要
探索速度轮滑直道双蹬技术的运动生物力学特征。通过文献资料法、视频数字解析等研究方法,分析速度轮滑运动员双蹬技术平刃蹬地双支撑阶段、外刃蹬地单支撑阶段、内刃蹬地单支撑阶段、内刃蹬地双支撑阶段的重心轨迹与下肢各关节角度变化。依据技术的运动生物力学参数,描述双蹬技术不同阶段的滑行特征,为技术训练与体育教学提供理论依据。
Objective to explore the biomechanical characteristics of double pedaling technique on straight track of speed roller skating. By using the methods of literature review and video digital analysis, this paper analyzes the center of gravity trajectory and lower limb joint angle changes of speed roller skaters’ double pedaling technology in the stages of flat edge pedaling and double support, outer edge pedaling and single support, inner edge pedaling and single support, and inner edge pedaling and double support. According to the biomechanical parameters of the technique, this paper describes the sliding characteristics of the double pedaling technique in different stages, so as to provide a theoretical basis for technical training and physical education.
