Study On The Dynamic Change Of World Track And Field Strength In The 27-31 Olympic Games

Track and field as the basis of competitive sports and Olympic medals,"soldier" has been a hotly contested spot,attaches great importance to much of the sports power.Therefore,the dynamic evolution and development trend of new period of in-depth study of the Olympic track and field sports level,explore its inherent characteristics and advantages of regional development group and the world track and field pattern of the actual establishment of our country in the world and the location and track and field sports of our country in a reasonable layout and strategic positioning on the Olympic project transport,promote China's rapid rise and has important practical significance.In this paper,the 27-31 Olympic Games track and field top eight athletes as the object,using the method of literature,mathematical statistics,logical analysis and other research methods,the world track and field strength of the countries and regions are divided into four regions(strong regional,relatively strong regional,regional and regional potential weak weak),explore the area dynamic 27-31 Olympic Games track and field athletics strength evolution and variation.The result shows:1 strong regional overall competitive strength,all-around and field group competitive strength of a small decline,walking track,groups of competitive strength,the group structure is stable;the overall competitive strength of transfer to a country,the United States to become the world's dominant track and field.2 a strong regional overall strength gradually weakened,a group of competitive strength of the largest decline,a walking group,field and Almighty group strength has increased slightly;the regional distribution of the competitive strength of the basic stability of space.3 the weaker regional overall competitive strength rise a little,a larger decline in overall competitive strength,walking group dropped,other groups of competitive strength.4 weak overall regional competitive strength remained,group further development and all-round development,the group generally has a larger increase,decrease,walking track groups of competitive power;competitive strength distribution range is larger,the area covered by the state changes frequently,liquidity is very strong,there is no stable members.5 China's overall competitive strength continues to increase,the development of men's track and field events show "go hand in hand" trend of development,men's track and field athletic strength has made great progress.6 Chinese also has to be developed all-around group,track groups of competitive strength small changes,enhance the walking and field group overall competitive power;competitive strength advantages highlighted,transfer from weaker regional strong regional countries.
