摘　　要：采用2台摄像机定点拍摄了辽宁省少年男子竞走暨半程马拉松比赛5000 m场地赛前6名运动员(年龄均在17岁以下)的正侧面技术,分别对每个运动员在比赛进行到1360、2560、3760 m处进行现场拍摄采样,采用爱捷运动录像反馈解析系统,对比赛现场拍摄的录像进行解析,采用扎齐奥尔斯基人体模型,进行图像采样,获得每个运动员一个复步的各个阶段和各个技术环节的定量数据,然后对数据进行整理、平滑和分析研究.依据"竞走定义"对关键技术环节进行诊断,同时,与国内外优秀竞走运动员的竞走技术进行对比分析,找出差距和不足,确定今后辽宁省少年男子竞走运动员努力训练的方向,为建立正确的竞走技术动力定型,为辽宁省及中国竞走后备力量的培养工作提供有益的参考.In this paper,two fixed-point cameras are used to film the 5000 meters venues of Liaoning Province Junior race and half marathon race,which filmed the front and side skills of the first six athletes(average age below 17)not only before the race but also at the 1360 meters,2560 meters and 3760 meters points.The Agile sports video analysis and feedback system are used to analyze the competition video.And used Siji manikin human body model,the image samplings are done.The quantitative data of each stage and technical aspect of a full step of each athlete are obtained and then the data is reorganied,smoothed and analyzed.According to the current technical state of athletes in juvenile male walking race in Liaoning Province,their key technical aspects based on“the definition of walking”and identifies the gaps and deficiencies are analyzed.By comparing with those outstanding walking race athletes home and abroad.A useful reference to determine the direction of efforts to train the juvenile men walking athletes of Liaoning Province in the future is provided,to finalize the design of setting up the right technical power of walking race and to reserve forces for the walking cultivating job of Liaoning Province and even our country.
