Evolution And Development Of Competitive Basketball Three-points

The three point of competitive basketball has been neglected since its origin and then it become an important means of attack for each teams,which has played a very important role in the overall development of competitive basketball.Through the method of literature,mathematical statistics,expert interviews,the origin and evolution of competitive basketball three-points and the influence of three-points on the future development of competitive basketball are studied.Based on the theory of regional imbalance and the theory of sustainable development,this paper expounds the influence of the development of the three-point ball on the competition in each stage during the evolution process of the three-points,and the influence of the development of the three-points on the future competitive basketball player selection,techniques and tactics,rules,and so on.Grasp the law of development so that people can be more objective and comprehensive To understand the function and significance of three-point ball and put forward some reasonable suggestions for the development of Chinese competitive basketball.The main results are as follows:1.The evolution of three-points can be divided into three periods: start-up period,all-round development period,and innovation and elevation period.In the initial period,the situation of three-point shooting is not highly correlated with the ranking of the team.Until the 1982-1983 season,the ranking was significantly related to the number of 3-pointers,and the weak teams had more 3-point shots.At 1994-1997 season,the indicators of the 3-pointers were improved.The higher the three-points hit rate in the three seasons,the smaller the ranking and the higher the ranking.During this period,teams that do well in three-pointers tend to be higher in rank.During the period of innovation and climbing,the record of 3-pointers has been refreshed time after time,and in this period,Strong teams will throw more 3-pointers,and will be able to maintain higher shooting efficiency.2.The motivation of the evolution of three-points is divided into internal cause and external cause,internal factor is the contradiction between social needs and basketball itself,and external cause is the change of traditional concept and the wideapplication of data analysis.3.Through the analysis of the three-point ball index of the men's basketball match in the recent five Olympic Games,it is found that the weak teams in the Olympic Games in 2000 and 2004 have more three-points shots.In the last three Olympic Games,the strong teams pay more attention to shot the three-points.The performance of the Chinese men's basketball team in the first three Olympic Games is not significantly different from that of the top four teams.In 2000,the three-points performance of the Olympic Games was better than that of the top four teams.In the last two Olympic Games,The index of three-points is significantly different from the top four teams,and the big difference with the top four teams.4.The three-points has great influence on the development of the future competitive basketball.In terms of rules,with the improvement of players' technical level and the emphasis on three-point shooting,the distance of shooting becomes more and more distant,and the rules of four-point ball and field expansion may be changed in the future.
