Using literature review related literature, understand the past and the present research situation of the research direction; Using mathematical statistics on the track and field achievements calculate the development coefficient, progressive, sequential coefficient and calm base than coefficient, making a dynamic index chart; Use of grey system theory, organize related data, the establishment of GM (1,1) model, based on the DPS data processing system for the next national youth predict the average scores of eight games track and field; Using the method of arrangement for each session of the project for the first eight's win the gold medal of the area and areas classified research.Due to the green Olympics (intercity athletes of teenagers), study of the events are a helpful aid in getting to know the our country athletics reserve personnel reserve, according to the performance change trend to further explore the dynamic changes of the youth track and field athletic talent performance trends, understand the regional distribution of track and field in the status quo, for provinces, cities and sports related functional departments to formulate training program to provide the reference. All items on the next track average forecast, favorable "green transport strategy" with "Olympic strategy", adjust the strategy.The results showed that:From champion result analysis comparison, women's sexual XiangQun overall speed showed a trend of decline, our youth woman fast XiangQun back-up talent pool is insufficient, because of the weak competitive strength, and the competitive level of adolescent man in continually improving; Chinese teenagers endurance level is gradually falling, and the overall competitive strength is falling and that the endurance XiangQun talent reserve in China is not optimistic; In recent games of power project development also is on the decline, to skip class project down obviously, bounce, flexibility and jumping the skill levels of teenagers falling, weak competitive strength; Men's all-around project competitive strength has improved significantly, but her all-around project has been in a state of disadvantage.According to the development trend of the former eight grade point average, the recent session of women's track and field speed XiangQun overall competitive level in the stagnant stage, men's overall competitive level has a certain improvement; Trough endurance project is currently in development in our country, the overall competitive level in declining, lack of reserve forces, sports level is relatively backward situation; Power XiangQun skip class project development overall declining trend; Comprehensive XiangQun man is superior to the women's all-around all-around project development projects, development of more stable.From the analysis of characteristics of regional distribution of track and field sports, east China area overall development more balanced, super competitive level, the strength is abundant, the tournament ranks the top gold medal; North China and northwest development is relatively stable, the number of all the Olympic gold medal is balanced; Gold weaker in northwest China, the project development relatively backward; Central and southern China, regional competitive strength fluctuation volatile; Southwest and northwest regional development is not stable, comprehensive strength is weak. |
