A Comparative Analysis Of The 100 Meters Technology Of Outstanding Men And Women In The Rio Olympic Games

For a long time,China's men's track and field movement has been in the world's second-class level,especially in the sprint of the disadvantages.In recent years,with the improvement of training level and the improvement of the quality of athletes,the gap between Chinese male sprinters and world-class athletes is gradually narrowing,and the scores of a large number of athletes are close to the 10s mark.For example,at the Asian Games in 2010,Chinese athlete Lao Yi won the first place in 100 meters sprint;2014 Inchon Asian Games,Su Bingtian,Zhang Peimeng in 10.10 seconds and 10.18 seconds swept the men's 100 meter crown runner up,creating a new history;The 2015 Beijing World Championships Men's 100 meter race,Su Bingtian ran out of 9.99 seconds,and for the first time in the final,it can be said that the breakthrough means that China's men's 100 m project began to impact the world first-class level,and in the match of China's 4 x 100m relay won the runner up in the men's broke Asian record;In 2016 Rio Olympic Games,Su Bingtian and Xie Zhenye got into the Olympic semi-final again at the same time and rewrote a new record,which is sufficient to prove the vigorous developing trend of our male 100 meters sprint.Therefore,under this background,this article starts from the perspective of male 100 meters technical,based on Rio Olympic male 100 meters game,uses the technology of the final three best,Bolt,Gatlin,De Glassey and two Chinese semi-finalists Su Bingtian,Xie Zhenye as the objects of study.This paper uses literature,documents,comparison analysis and other methodology.This paper basically discusses the distance between Chinese male athletes and world top ones and why the distance exists.This paper tries to provide some reference for the future training of Chinese sprinter coaches and athletes,and make great efforts for the continuous improvement of theory and method of Chinese sprint.In this paper,the following conclusions can be drawn:1 Chinese athletes still have improvement space in step length,stride frequency index there are certain gap,especially in the ascension of step index.And foreign athletes are better than Su Bingtian and Xie Zhenye in the various aspects of the technology in the running.To a certain extent their technologies are more scientific and reasonable.2 Changing speed curve in 100 meters of Bolt,Gatlin and De Grasse resembles the trend of of "Dam type".Changing speed curve in 100 meters of Su Bingtian and Xie Zhenye's movements tend to be like "Two-top type" curve model.3 From the starting time perspective,Chinese athletes are better than foreign players.Seeing from the speed accumulation period,China athletes are able to compete with excellent athletes of the world level;From the maximum speed period,the maximum speed of Chinese athletes appeared earlier and kept a relatively shorter time,the maximum speed of foreign athletes appear late and maintain strong ability;Chinese athletes show a the speed decreasing gap significantly compared with foreign athletes.4 Based on the conclusions above,there come the following suggestions:1)In the case of certain frequency,effectively improve the step length.2)The pursuit of full speed curve of scientific and reasonable.3)Strengthen the speed endurance training to improve the ability to maintain maximum speed.4)Strengthen the upper limb strength training,promoting muscle coordination and relaxation,improve energy material supply.
