【摘要】：竞走运动是竞技运动中耐力性要求比较高的运动,我国在竞走方面取得过辉煌的成绩,也属于世界竞走强国之列。但是最近几年我国运动员在世界大赛中并未取得世界强国应有的优异运动成绩,尤其是2008年在我国举行的奥运会,运动成绩也不理想,更有用完成前期设立的运动目标。尤其是我国青年运动员的成绩更不理想,在南京举行的青奥会,前八名运动员中竟然没有中国运动员的身影,在太仓世界杯我国高文魁虽然获得了第一名的成绩,但我国其他参赛的运动员,并没有获得很好的成绩,值得我国运动员、教练员以及科研工作者的深思与反省。所以本研究就针对青奥会男子10公里竞走前五名运动员以及太仓世界杯我国三名运动员比赛情况进行现场摄像,获得运动员在不同的圈数之间的运动影像。并对获得的一手影像资料进行处理与分析,以期望能够分析出影响我国青年男子10公里竞走运动员竞走成绩的原因,进行分析并得出结论:(1)我国男子高水平10公里竞走运动员在步长与步频方面存在较大的差异,尤其是三名运动员步频普遍较快,步长相对较小,尤其是冷晓,具有较快的步频,但是步长却较小;(2)我国竞走运动员存在较长的腾空时间,在摆动阶段时间来看,前摆时间普遍大于后摆时间,符合人体正常的生理构造,以及重心的垂直位移变化较大;(3)我国男子高水平10公里竞走运动员在支撑阶段膝关节角度、肘关节角度、地瞬间脚与地面夹角以及支撑瞬间踝关节角度方面基本符合竞走技术的要求,在比赛过程中也可以得到裁判认可,但是其统计学结果标准差比较大。
[Abstract]:Race walking is relatively high endurance requirements of competitive sports, China has made brilliant achievements in the race, but also to the world walking power. But in recent years China's athletes in the world series did not achieve world power due to the excellent athletic performance, especially in the 2008 Olympic Games held in China the movement, the result is not satisfactory, more useful targets completed the preliminary set up. Especially our young athletes is not ideal, held in Nanjing Youth Olympic Games, the top eight athletes would not Chinese players, the world cup in Taicang in China, although Gao Wenkui won the first prize achievements. But in other Chinese athletes, and did not get good results, worthy of our athletes, coaches and researchers to ponder and reflect on. So this study is aimed at the Youth Olympic Games 10 km men Walking the top five athletes of the world cup in Taicang and three Chinese athletes to live video, get between athletes in different sports circles. And image processing and analysis of the first hand data, analysis of the reasons to expect to influence Chinese young men's 10 km race walkers score. Analyze and draw conclusions: (1) China high level men's 10 km race walking athletes have difference in length and stride frequency, especially the three athletes stride is generally faster, step size is relatively small, especially cold Xiao, has the advantages of high frequency, but the step size is smaller; (2) Chinese athletes who are the longer flight time, during the swing phase of time, before the time is larger than the swing time, with normal human physiological structure, and the vertical displacement of the center of gravity of the great change of Chinese men (3); The high level of 10 km race walking athletes during the support phase knee joint angle, elbow angle, moment and angle between foot and ground support moment ankle angle consistent with walking technique requirements, in the course of the game can also get the referee recognized, but the statistical results of standard deviation is relatively large.
