摘　　要：为了探索博尔特屡破百米世界纪录的奥秘及为中国短跑运动发展提供一定的理论参考,运用信息技术为主的方法,对博尔特参加的北京奥运会和柏林世锦赛两项赛事的100m决赛进行运动学技术分析,结果表明:奥运会后博尔特经过刻苦训练步长、步频及起跑反应能力均有所提高;世锦赛途中跑支撑阶段支撑腿膝角缓冲幅度更大,踝关节背屈、跖屈角度增加,获得了更大的后蹬力,同时摆动腿折叠技术更加合理有效;如果博尔特起跑更加顺利,冲刺阶段全力发挥,那么百米世界纪录还将再度刷新。By using the methods of information technology methods,this article analyses Bolt＇s one-hundred running skill of Beijing Olympic Games and Berlin World Championships,in order to explore the mystery of Bolt 100m record-breaking and provide a theoretic reference for it.The result shows that Bolt＇s step length,stride frequency and capacity increased after a hard training;the knee angle of support leg had become larger,the ankle plantar flexion increased,so that he obtains much more pedal force,meanwhile,Swinging Leg Movement Skill is more reasonable and effective;If Bolt starts more smoothly,Spring phase full plays,the world record also will again refresh.
