刘翔2012伦敦奥运会夺冠的可能性探究——以刘翔、罗伯斯在英国伯明翰室内赛60m栏决赛的技术分析为例

Exploring the Possibility of Liu Xiang's Winning in the 2012 London Olympic Games——An illustration on the Technical Analysis of Liu Xiang and Robles in the 60 Meters Hurdles Finals in Birmingham

运用信息技术为主要研究方法,对刘翔与罗伯斯在伯明翰的60m栏室内赛的时间特征进行了比较分析。研究显示:刘翔八步改七步上栏成效尽显,比赛虽"胶着"但仍以明显优势取胜并独占世界短跨项目的第一集团。同时还指出:短距离速度性项目反应时固然重要,但非决定性因素;刘翔如果反应时能提高到罗伯斯的水平,并且七步上栏技术更为成熟,那么刘翔2012伦敦奥运会夺冠的可能性将会很大甚至再次打破110m栏世界纪录。

Using the information technology as the main method of study,I make a comparative analysis of Liu Xiang＇s and Roberts＇s time features in 60 meters hurdles final in the 2012 Birmingham Indoor Track and Field Games.It shows that Liu Xiang＇s changing of the eight steps into seven steps before hurdling makes a great contribution to his success by obvious advantages,which lets him take the first place in the short-distance hurdles competition in the world.It also indicates that reaction time is very important but not decisive in the short-distance items.If Liu＇s reaction time could be raised to the level of Robles＇s,the possibility of Liu Xiang＇s being the champion in the 2012 London Olympic Games will be great,and he will even break the word record of the 110 meters hurdles.
