Research On The World Structure Of Men's Freestyle Competitive Strength In Rio Olympic Games

Swimming as a sporting event started in the middle of the 19 th century.It is one of the major gold medalists in the Olympic Games.Swimming and the “119 Project” jointly designated by the athletics and aquatic projects,as major items,have gained widespread influence and attracted much more attention.Among them,freestyle is the largest number among the five major categories of competitive swimming and the earliest gold medal in the Olympic Games.It is also one of the fastest growing sports in China.At the same time,it is widely concerned because the men’s freestyle item represented by Sun Yang has a stable growth point in the last two games.In view of the sustainable development of competitive sports in our country,we should base on the advantages of the project,the advantages and disadvantages of submarine attaches great importance to the development and improvement of the project development experience,the continuous cycle of cumulative advantage and potential advantages of the project and the development model of China.Thus the men’s freestyle swimming sports is selected as the research content of this thesis.Based on the methods of literature,mathematical statistics,comparative analysis,RSR rank sum ratio method and Boston matrix,taking the competition data as the support,the Rio Olympic Games as the main support,the top eight individual men’s freestyle swimmers in Rio Olympic Games as the research object,and guided by the cyclic cumulative causality,this thesis studies the competitive strength of men’s freestyle swimming in Rio Olympic Games along the line of intercontinental country athlete performance,and analyzes the competition pattern of men’s freestyle in the world today.By the analysis of the distribution pattern of the world the Rio Olympics men’s freestyle competitive strength,this thesis aims to provide help for the next step in the development planning of China Men’s free travel and provide reference for the introduction and development strategy for the selection of Chinese men’s freestyle day after training,learning object selection and training concept formulation.The study concluded that:1.Intercontinental features: North America and Europe still occupy an absolute dominant position.According to the RSR rank sum ratio method,the comprehensive strength of the six contestants is divided into four different classes of groups.Europe and North America belong to the A grade,Oceania belongs to the B grade,Asia belongs to C,and Africa and South America belong to the D level.Among them,Europe has the strongest overall strength.And it’s top eight width and the medal width are the highest in the world.In contrast,other continents are short of width,which is expressed in single country’s competitive sports.North America is headed by theUS,Australia is the main form of Oceania,Asia is headed by China,Africa is South Africa,and South America is Brazil.Through the study of Boston’s matrix method,Oceania and Europe showed a high growth rate of high occupancy.Asia and North America showed a low growth rate of high occupancy.Africa showed a high growth rate of low occupancy while South America showed a low growth rate of low occupancy.2.National characteristics: The performance of the project is not balanced,and the traditional strong power still occupies the absolute hegemony.Based on the RSR rank and ratio method,the top 16 countries are divided into four ABCD strength groups according to their strength.The United States,Australia and Italy belong to Group A.China,France,the United Kingdom and South Africa belong to Group B.Belgium,Canada and Brazil belong to Group C.And Ukraine,Germany,Japan,Lithuania,Russia and Norwa belong to Group D.The United States takes the absolute advantage in medals and the first eight thicknesses.Australia ranks second.Although Italy has the medal thickness,its width is not enough,and there is a gap between the two countries.France and Britain have a certain width and thickness of the first eight,but the wide thickness of the medals is not enough,especially in Britain.China,South Africa and the countries of the C and D group are mainly shown in individual competitions.The thickness of the medal and the top eight is seriously inadequate,especially China,although it has a certain medal thickness,the width is seriously inadequate.So it is urgent to expand the country’s top eight and the medal width.3.Competition results: If the performance characteristics of different projects are different,the characteristics of different rank between the same project are different.The overall results of the 50 meter project showed a downward trend.The gap between four to eight and the top three was large,and the results were polarized.The overall performance of the 100 meter project shows a downward trend.The gap between the four to eight and the top three is reduced,and the competition is increasingly fierce.The overall performance of the 200 meter project is on the rise.The gap between the four to eight and the top three is reduced,and the competition is increasingly fierce.The overall results of the 400 meters project showed an upward trend.But the internal two heads were divided seriously;the middle ranking competition was increasingly fierce.The overall performance of the 1500 meter project is on the rise.The gap between four to eight and the top three is reduced,and the competition is increasingly fierce.The performance characteristics of the reaction time,the journey and the side performance are different in different items.Short range projects are more intense.The reactivity and explosive force of the athletes are high,and the results of the reaction are generally superior to those of the middle and long distance athletes.At the same time,there are great differences in the performance of the eight athletes,the first three are not dominant,mainly in the midway and tothe side sprint to win.The middle and long distance project is based on the middle and edge results,and the athletes’ competition rhythm and physical ability are high,and the contribution rate of the reaction time is small.And the first three people generally show that the rhythm of the game is strong control ability;speed and physical distribution are more reasonable and so on.4.National economic development level: The country’s world GDP rankings are correlated with their competitive RSRs.The correlation coefficient between world rankings and RSRs is-0.420.The higher the rank of national GDP,the greater the RSR,the stronger the country’s overall competitive strength.5.Athlete characteristics: There are differences in terms of age,height,weight,Laurel index and Kettlei index among different sportsmen of different categories.There are significant differences among short-distance sportsmen,generally showing the top three to be more than four to eight,while the long-range sports are more different Small,and there is a tendency to centralize.6.The characteristics of Chinese men’s freestyle: the men’s freestyle gold medal width is narrow,prize winning thickness is low,and the overall top eight advantages are limited—there is only one leading figure Sun Yang.Compared with the world elite sports,the following two characteristics are presented:(1)at the individual level,athletes in China,except Sun Yang,generally show small age,thin body,low body thickness and fullness.(2)At the level of the individual competition,the experience of the competition is limited,and the technology is not proficient in the way and to the side stage,and the physical fitness and speed are at a serious disadvantage.Therefore,the men’s freestyle of our country needs a course of development if we want to keep a foothold in the world swimming arena.
