| Athletics is the basic item of competitive sports and the cornerstone of the development of competitive sports.It has always been the commanding height of competition among various countries(regions).After experiencing the loss of the gold medal in the Beijing Olympic Games,China’s track and field achieved good results in the “1516 Breakthrough Action Plan” cycle.China’s track and field has experienced ten years of volatility development,and the athletic strength of track and field has made progress in the reform process,but at the same time it has also revealed new problems in the development of China’s track and field.Therefore,it accurately locates the strength of China’s track and field sports and clarifies the development of China’s track and field.It is necessary to clarify the status quo of China’s track and field development.In this paper,using literature method,mathematical statistics method,cluster analysis and other methods,the current eight athletes’ scores of the 12th-16 th World Championships in Athletics are taken as the research object,and the national(region)as the basic unit is used for cluster analysis.The law divides the national competitive strength into the first,second and third power groups,compares and analyzes the competitive strength of China and the I and II power group countries,locates the group position of China’s track and field athletic strength,and analyzes China’s track and field sports with time as the main line.The dynamic change characteristics of strength development,analyze the factors restricting the development of China’s track and field,propose countermeasures,and provide a certain reference for the development of track and field in China.The study mainly draws the following conclusions:1.The balance of the scores of the scores in the 12th-16 th World Championships in Athletics is as follows: the top ten countries in the rankings occupy 62.49% of the scores in the proportion of 10.10% of the countries,and 89.90% of the scores in the standings.The country only received 37.51% of the scores.2.China’s track and field athletic strength is ranked fifth in the second strength group with a score of 346 points.The position of the group in which our country is located has been forced by Poland and France,and has not yet formed a stable group position.China’s potential advantage project women’s marathon and the first and second strength group countries’ advantages and potential advantages project coverage is small,can be used as a key breakthrough project to consolidate and improve the existing group position in China.3.China’s track and field scores are mainly concentrated on men’s walking,women’s walking,women’s throwing,and women’s marathon.Women’s throwing is the only project with high competitiveness in China,but it faces strong competition from Germany.The strength of men’s and women’s walking in China has been challenged with the return of Russian track and field.The men’s jumping project with better performance is also facing the second strength group countries.4.China’s track and field advantage projects are: women’s throwing(41.70%),women’s walking(62.56%),men’s walking(76.03%);potential advantages are: men’s jump(87.08%),women’s marathon(93.25%).China’s advantage projects women’s throwing,women’s competitive sports strength has improved significantly,men’s competitive sports strength in the volatility;potential advantage project women’s marathon performance has been showing a downward trend,men’s jump performance increased.The advantages of the first and second strength group countries have large differences in coverage and potential overlap,and there is a certain overlap phenomenon.The development trend is generally characterized by alternating evolution and diversification.5.At the 12th-16 th World Championships in Athletics,the fluctuations of track and field performance in China were small and the overall strength was gradually improved.The number of athletes entering the top eight athletes in China has a staggered upward trend.The strength of China’s impact medals is gradually strengthening,and the probability of hitting gold medals is gradually increasing,and the rate of training for athletes is increasing.6.The scoring ability of China’s track and field events is single,and the characteristics of non-equilibrium are obvious.The gap between male and female athletic strength is still obvious.The main scoring items for men are: 20 km walking,50 km walking,long jump;women’s main scoring items are: 20 km walking,shot,hammer,javelin.Through the statistical analysis of the scores of the scores,some suggestions are given for the current development of track and field in China:(1)The complementary combination of the national system and the market mechanism is the key to realizing the sustainable development of China’s track and field sports strength.(2)The optimization and training of track and field reserve talents is an important measure for China’s trackand field sports strength to maintain its advantages and promote development.(3)The combination of key construction and differential development is an effective means of the development of China’s track and field events.(4)The perfect event structure is a powerful assistant for the development of athletics in China.(5)Drawing on the experience of the “1516 Breakthrough Action Plan” to build a medium and long-term development plan for China’s track and field. |
