【摘要】：伴隨著我國對競技體育的不斷投入,科技與體育的不斷交融,現(xiàn)階段的體育事業(yè)有了整體性的提高,我國現(xiàn)階段正處于向體育強國轉型的時期。在這樣的背景下,我國的短跑項目也有了實質性的突破�；诖�,我們有必要對現(xiàn)今我國選手與世界百米頂級運動員全程百米跑四階段的時間、空間技術特征差異進行研究。其目的是為我國短跑訓練、教學提供參考。本研究以2015年世界田徑錦標賽男子百米決賽的冠亞季軍及我國選手蘇炳添和張培萌為研究對象。采用文獻資料法、數(shù)理統(tǒng)計法、信息技術法等,對中外百米選手的技術時空特征進行全面的比較、分析。本文得出如下研究成果:(1)起跑階段,我國的好手的平均反應時慢于世界頂尖級選手的平均反應時,且我國選手的起跑反應能力不穩(wěn)定。(2)加速跑階段,我國的好手的平均水平慢于世界頂尖級選手的平均水平,且我國選手的加速能力不穩(wěn)定。(3)途中跑階段,我國的途中跑時間明顯少于世界的平均水平。(4)沖刺跑階段,我國選手的沖刺能力明顯較世界頂級選手差,提示我國的教練員與運動員在日后的訓練中,要進一步加強速度耐力訓練與爆發(fā)力訓練。(5)蘇、張的壓線技術也不如世界頂級高手的壓線技術,其軀干沒有很明顯的向前傾斜的態(tài)勢。
[Abstract]:With the continuous investment in competitive sports and the blend of science and technology with sports, the sports cause has been improved integrally at the present stage, and our country is in the period of transforming into a powerful sports country at the present stage. In this context, our country's sprint has also made a substantial breakthrough. Based on this, it is necessary for us to study the difference of time and space technical characteristics between the present Chinese athletes and the world's top 100-meter athletes in the four stages of the whole 100-meter race. Its purpose is to provide reference for our country sprint training and teaching. In this study, the second runner-up of the men's 100-meter final in the 2015 World Athletics Championships and the Chinese contestants Su Bingtian and Zhang Peimeng were selected as the research subjects. By using the methods of literature, mathematical statistics and information technology, this paper makes a comprehensive comparison and analysis of the space-time characteristics of Chinese and foreign 100-meter contestants. The results are as follows: (1) in the starting stage, the average reaction time of the good hands in our country is slower than that of the top players in the world, and the ability of starting reaction of the Chinese players is unstable. (2) accelerating the running stage, the average reaction time of the good hands in our country is slower than that of the world's top players. The average level of good hands in our country is slower than the average level of the world's top runners, and the acceleration ability of our country's athletes is unstable. (3) in the en route running stage, the time of our country's en route running is obviously less than the world's average level. (4) the sprint stage, The sprint ability of the Chinese athletes is obviously worse than that of the top players in the world, suggesting that our coaches and athletes should further strengthen the speed endurance training and explosive force training in the future training. (5) Su, Zhang's line pressing technology is not as good as the world's top experts, its torso has no obvious forward tilt trend.
