Research On The Development Trend Of The Offensive And Defensive Characteristics Of The Chinese Men's Basketball Tea

After more than one hundred years of development since the advent of basketball,various regions and countries have gradually formed their unique offensive and defensive characteristics through constant exchanges and exchanges,and continue to integrate under the influence of globalization.Chinese men’s basketball team has not performed very well in the recent world competitions,and its offensive and defensive characteristics are not distinct.In the nine world competitions that China has participated in since 2000,the best result was the 8th place in Athens Olympic Games and Beijing Olympic Games.In other World competitions,China failed to enter the top10.In 2019,China won the 24 th place in the Men’s Basketball World Cup,which is the worst record in nearly 20 years.Generally speaking,the results of the Chinese men’s basketball team have fluctuated in the past 20 years,and showed a downward trend after the 2008 Beijing Olympic Games.How to make the Chinese men’s basketball team out of the trough,improve the competitive level,narrow the gap,rebuild the style of technique and tactics,is a question worth discussing.Using comparative analysis,grey correlation analysis,rank sum ratio comprehensive evaluation analysis and other research methods,based on the understanding and understanding of basketball,this paper carries out a historical review of the offensive and defensive characteristics of Chinese men’s basketball,and summarizes the changing trend of the offensive and defensive characteristics of Chinese men’s basketball through comprehensive analysis and research of conventional data indicators and high-level data indicators.Summarizing the advantages and disadvantages of Chinese men’s basketball team is of great significance to the reasonable preparation of Chinese men’s basketball team and the development of Chinese basketball career.Using grey correlation analysis and rank sum ratio comprehensive evaluation analysis,based on the statistics of offensive and defensive indicators in the 9th World Series from 2000 to 2019,this paper compares and analyzes the horizontal and vertical aspects of Chinese men’s basketball competition and the advantages and disadvantages of both sides of the offensive and defensive.With the help of the dynamic change of high-level indicators,this paper further analyzes the evolution trend of the offensive and defensive characteristics of Chinese men’s basketball,so as to provide a target for the qualification of Chinese men’s basketball for the Paris Olympic Games and prepare for the following competitions.The following conclusions are drawn from the research:(1)The body shape of Chinese men’s basketball players is not balanced,their average height is above the world level,their weight and Ketole index are declining,their athletic ability,speed and flexibility are improved,but they lack the ability to fight in fast-paced and high-intensity games,their mistakes are increased,their technical movements are deformed,and their competitive level is restricted.(2)The correlation degree of indicators in previous competitions is analyzed vertically by grey correlation method.The indicators that are most closely related to the outcome of Chinese men’s basketball are three indexes of two-point shots,including the number of two-point shots,the number of two-point shots and the percentage of two-point shots,followed by the percentage of free throws and defensive rebounds.(3)According to the rank-sum ratio comprehensive evaluation analysis,the attacking ability of Chinese men’s basketball team was the best in the 2006 World Championships in Japan.The attacking grade of Chinese men’s basketball team was B,ranking seventh among 24 teams.In 2008,Beijing Olympic Games had the best defensive ability.The defensive rating was B,ranking the fourth among the 12 participating teams.In 2008 Beijing Olympic Games,the overall strength of attack and defense was the best,ranking the sixth at Grade C.On the offensive side,the main problems are the poor ability to scramble for offensive rebounds,the number of turnovers and the lack of scoring ability.On the defensive side,the main problems are fewer steals and lost points.On the whole,the defensive ability is stronger than the offensive ability.(4)The ability of players in different positions of Chinese men’s basketball team is unbalanced.The strength of interior players is relatively prominent,and the gap between frontline players and guard players in physical and technical aspects is getting larger and larger.The offensive and defensive ends mainly rely on the inner ability to drive,with monotonous tactics and single playing style.Offensive rebound and the number of turnovers are the weaknesses of Chinese men’s basketball for a long time.The proportion of three-point shot in the tactical system of the team has increased,but the stability is poor and the hit rate fluctuates greatly.(5)From 2000 to 2002,Chinese men’s basketball gradually lost the characteristics of "fast,accurate and smart" and turned to "large-scale".In this stage,the average height increased,the position attack increased,the perimeter technical ability decreased,the use of tactics decreased,and the playing style retained the characteristics of "internal and external combination".From 2003 to 2009,the characteristics of "large-scale" and "Yao core" were gradually formed,with excellent defensive ability,offensive focus shifted to the interior,position attack and interior players scored more,and the offensive rhythm slowed down.The perimeter attack was not the tactical focus of the Chinese men’s basketball team,and it won the eighth place in the Olympic Games for two times by virtue of its excellent interior strength.From 2010 to 2016,the core of Chinese men’s basketball was still dominated by the interior,the number of three-point shots increased but the percentage was not high,the average points per game increased,and the new style characteristics of Chinese men’s basketball could not take shape due to the slow transition of the old and the new,personnel fault and frequent change of coaches.During this period,the record of the world series was 15 losses and one win.After 2017,the strength of both ends of Chinese men’s basketball has been improved.Based on the inside,Chinese men’s basketball drives the outside to form offensive opportunities with the help of screen,but the outside players’ shooting ability is not outstanding,unable to effectively convert offensive opportunities into points,and the characteristics are still dominated by the inside.
