摘要
竞走是我国田径传统的优势项目,但近年来男、女竞走运动员在国际比赛中成绩下滑。针对十运会我国男、女20 km竞走前5名运动员的运动技术表现,采用新的标尺标定方法,通过二维录像平面解析研究运动员的运动技术特征。主要研究结果:竞走阶段的合理划分;步长、步频;头部速度特征;关键身体环节角度变化特征;角速度变化特征;身体垂直位移特征和运动技术视频图像信息等7个方面,并得出相应的结论。
Race walking is our traditional elite event in track and fields. However, the performance of our man and woman walkers declined in international competition in recent years. Based on the technique of man and woman 20 km walkers at top 5 in the 10^th National Games ,and using the new method of staff guage and two-dimensional video analysis ,this paper made all-round analysis on technical characters. The result showed that the rational phase of race walking was stride and frequency of pace, the angle change of key body joint, the angle speed change of main body joint ,the change of vertical displacement of body and the character of technical video image. The corresponding conclusions were drawn out.
