Through the horizontal and vertical comparative analysis of the results of the track and field series of college students across the country,this study finds out the potential rules and problems existing in the development of the track and field level of college students in recent six years.It focuses on the development trend and law of college students' Analysis,in order to provide theoretical support for the development of athletics level of college students in our country.The theme of this paper is the athletics level of Chinese college students in 12-17 years.It is an overall analysis of the development trend of this group of college students.Because the most realistic and most direct indicator of the athletics level of college students is the competition result,Therefore,this paper selects the highest-level track and field college athletics high-level group and the ordinary PE college athletics college group held each 12-17 each year.The average scores of the top three students are the research objects.Through the data processing,the development trend of the top three scores of each group of university track and field series events and men's and women's events will be presented as "two tables and one chart",which are respectively the comparison table of development coefficient,the comparison table of chain development coefficient,dynamic picture.Finally,using standard sports competition score system scoring,the performance of GroupA and B comparative analysis.By comparing the horizontal and vertical results of "two tables and one chart" and two sets of results of A and B,it is found that the percentage of each item in each group is higher than that of women,especially in 13 years.The level of speed category and The stamina was higher than that of stamina;the stamina was the lowest among men in 13 years and the women were at a low level in 13 and 17 years;the sprinter was higher at 13 and 17 years and the highest at 13 years;Women's 100 meters hurdle in recent years,the level of sustained rise phenomenon.In Group B,the level of each project was relativelyhigh in 12 years;the short grades of women in short span gradually declined in recent years;the endurance men's grades declined significantly in 13 and 17 years;the low and unstable men's and women's pole vaults in the men's 20,000 m walking race and men's and women's jumpers were lower.Finally,the following conclusions are drawn: 1.The percentage of male athletes in Group A is higher than that of women in all sports.2.Speed class items overall higher level of competition.Except for individual projects,other projects showed a slight downward trend in the past six years.Endurance class group development trend as a whole "wave"-like development.4.The jumping items in the power class group showed a "U" type development trend,and the throwing items showed a "V" shape.5.Some "unpopular projects" are characterized by unstable development,relatively low level of athletic performance and great changes in performance.6.The gap between Group A and Group B has been gradually narrowing.Some projects are even closer to and above the level of Group B,except for some "unpopular projects".
