A Study On Tlhe Characteristics Of Athletes' Performance In The Track And Field All-around Events Of The Olympic And World Championships

The differences and characteristics of the athletes' achievements in the world championships and the Olympic Games in the women's seven events and the men's decathlon are the research goals.In this paper,2000,2004,2004,2012,the OlympicGames in 2016,the 8th,9th and 10 th,the 11 th,12th,13 th,14th and 15 th = world championship in the women's seven men,10 decathlon athlete's performance as the research basis for(excluding didn't finish the game and the lack of one or more of the data).In this study,we used the method of literature and mathematical statistics to build a tracking database.Research results,using the general linear regression analyses the present situation of the world championships and Olympic Games,an analysis heptathlon rolling performance in the Olympic Games,world championships performance is more stable.The highest point appeared in the Olympic Games,and during the world championships has fallen back.It shows that the women's heptathlon athletes are trained specifically around the Olympic year.Combining building blocks and Xiang Qun training theory,analysis of data available,the contribution rate of the high jump is the most obvious,so you can focus on developing physical fitness class fast strength Xiang Qun,help to increase the high jump,long jump,etc.Using the general linear regression to analyze the current situation of the world championships and the Olympic Games,it is concluded that the achievements of the decathlon in the Olympic Games are undulating and the world championships are more stable.The highest point appeared in the Olympic Games,and during the world championships has fallen back.The men's decathlon athletes were trained in a targeted way around the Olympic year.Combined with the theory of building blocks,it is beneficial to give full play to the advantages of the project.Therefore,in the men's decathlon,it is necessary to exert the advantage of the project with the greatest contribution to the overall achievement.Blocks theory reflects the universal non equilibrium state of the project,by strengthening advantage projects can to a certain extent,make up for the weak,but at the same time,also want to note that not all compensation are effective,the physical quality of the relationship between positive correlation,negative correlation,so for advantage compensation is not unlimited increase,requires a combination of corresponding scientific training methods.
