Analysis Of The Difference Between The Men’s 100 Meter Technology In China

Track and field is known as the "mother of sports", is a basic project in sports exercise. Sprint is the basis of project of track and field sports,has a special place in track and field. The dash is all athletics competition is most intense,the most entertaining,especially the men’s 100 m air war.100 meter world records have been rewritten many times, to achieve increased to 9.58 seconds. Although China’s sprint level has been greatly improved in a certain extent, the result is still with the world high level difference is relatively large. Through a comparative study of Bolt and Lao Yi find Lao Yi insufficient 100 meters running in technology,in the training in the future put forward specific measures and improvement scheme,is conducive to improve the performance of 100 meters, can also give our elite sprinters to provide reference and improvementUsain Bolt,the world’s fastest man;Lao Yi,Shinco Asian "flying 100 meters",the technique of sprint is the typical characteristics of the China. This research mainly using the information technology method, based on the 2010 Guangzhou Asian Games 100 meters champion Lao Yi and 2009 in Berlin World Championships 100 meters champion compared Bolt who won the twogame of two people the 100 meter technology,the study pointed out:1.The growth of Bolt the result curve appeared two peak,while the growth of Lao Yi the result appears only one peak curve. Lao Yi 100 meters result has not appeared second peaks,by using scientific means to improve the sprint training,can continue to create good grades or to continue to maintain a high level of exercise.2.Lao Yi,step index slightly better than Bolt,that Lao Yi step ability is good,But the bigger frequency index Lao Yi and Bolt gap,that Lao Yi frequency ability is weak.3.Bolt single step time is shorter than that of Lao Yi,mainly in supporting time is obviously shorter than that of Lao Yi,but there are some differences among the two people support vacated bibi excellent athletes in the world;Lao Yi running support phase technology exist great shortage,resulting in the loss of horizontal velocity is more.4.Lao Yi and Bolt are not ideal and the world level athletes compared to the larger gap,needs to be improved,the starting reaction Lao Yi than Bolt more slowly. Use a shorter time to Bolt,a shorter distance to complete acceleration run into running on stage,accelerating ability was stronger than Lao Yi.5.Lao Yi’s total acceleration distance shorter than Bolt 10 meters,resulting in the 100 meters late decreased faster; the maximum speed of Lao Yi and maximum velocitykeeping ability and Bolt compared gap is too big.6.Lao Yi throughout the sprint stage is not completely relaxed, the movement is stiff;and Bolt show superior ability to relax,it is meaning workers need to learn.
