Research On The Law Of Chinese Athletes Turning Into Talents From The Perspective Of Item Group Theory

In order to shorten the time of talent training and improve the utilization rate of talents,this paper analyzes the basic physical characteristics and training cycle of the athletes who have won Olympic MEDALS and discusses the characteristics of the movement among the athletes who have won Olympic MEDALS.By using the method of literature,comparative analysis,mathematical statistics and data analysis,this paper sorts out some internal relations among Chinese Olympic medalists who have changed events,and mainly draws the following conclusions:1.In China,the Olympic medal athletes with the experience of sports conversion show a trend of "Yin sheng Yang decline" and "east more west less",and the number of people with the same group of sports conversion is higher than the number of people with different groups of sports conversion,and the girls with the same group of sports conversion possibility is the highest.2.Athletes’ transfer out and transfer out items are not evenly distributed,in which the transfer out items mainly focus on the ski-dominated performance and the quick-strength category dominated by physical strength,while gymnastics and track and field events have the most transfer out.In the transferred project,the main performance items are difficulty and fighting confrontation,and the diving project has been transferred to.3.Item turn up in our country athletes in competitive factors: divided into technical turn technology turn up most likely,according to the action structure,divided into multiple action structure item most likely multiple action structure turns,according to the trend of the development of division of the project: turn advantage projects turn advantage projects most likely,according to the project participants divided: turn individual projects turn individual projects most likely.And the athletes with the same special quality,similar sports,similar body characteristics of the best effect.4.The average age of Chinese Olympic medalist athletes with conversion experience is 12.63±3.26 years old.The average age of male athletes is earlier than that of female athletes,among which the earliest one is 11.44±3.48 years old,and the latest one is 15.57±1.72 years old.The mean adult age was 22.18±3.90 years old,and there was no significant difference between male and female students.The mean adult age was 20.63±3.78 years old,and the mean adult age was 25.29±3.73 years old.5.The average training time of Chinese Olympic medalists who have the experience of changing events is 3.66 years.and the average training time is 2.01 years,when the transfer effect is the best.The average training time after transfer was 9.55 years.The average training time of girls was shorter than that of boys,and the training time of the same group was shorter than that of the different groups.
