摘要:: 采用文献资料法、信息技术法、数理统计法，对2015年世界田径锦标赛男子百米决赛中苏炳添和博尔特的100 m技术的时空特征进行剖析，其目的是分析我国选手苏炳添与博尔特之间的技术差异性，以便为苏炳添日后改进训练提供参考。结果表明：1）苏炳添与博尔特之间的技术差异主要在于“步长”上，博尔特步长明显长于苏炳添。2）苏炳添的步频指数不理想，即步长、步频呈现非均衡发展，而博尔特步频指数较为合理，步长、步频呈现均衡发展态势。研究认为：苏炳添应在保持步频的背景下，以增加步长的训练为突破口，即：增大前摆角度、支撑腿缓冲角度、膝关节角度以及折叠程度等的训练。

Abstract:: By the methods of documentary, information technology,mathematical statistics research methods,such as hundreds of meters of the 2015 world athletics championship final sino-soviet bean addition and bolt＇s 100-meter run technology,this paper analyzes the characteristics of space and time,its purpose is to analyze our country athletes Su Bing add with the technical differences between bolt,in order to provide reference for Sue advanced training in the future.The results showed that:1)Sue,between the technical difference lies mainly in “step” on,bolt step significantly longer than Su Bing add.2)Su Bing add stride frequency index is not ideal,namely,step length,stride frequency present non-balanced development,while bolt,stride frequency index is relatively reasonable,step length,stride frequency equilibrium development situation.Research suggests:Sue should be under the background of keep pace,step length in order to increase training as the breakthrough point,namely:increase the front Angle,Angle of the supporting leg buffer and knee joint Angle,and the training of the degree of folding.
