Analysis Of Creating Shooting Opportunities In Men's Basketball Competition Of The 31st Olympic Games

As one of the three most popular sports,basketball has the function of activating body and strengthening body.As a competitive sport,it is a sport in which the winner is the one who scores more in a specified period of time,and the shooting is the only means of scoring in the basketball game.Therefore,the importance of shooting skills in the game is self-evident,and it is more important to create good shooting opportunities.The Olympic Games every four years is a great event in the world sports field,which represents the highest level of each country's sports.The research on the ability to create shot opportunities in the Olympic men's basketball competition can find the commonality and difference of the shot opportunities created by each team and the overall characteristics of the shot opportunities created by the world's top teams.The aim is to provide effective theoretical basis for men's basketball training and competition guidance.This study selected 2016 Rio DE janeiro Olympic Games men's basketball team 31 38 games(30 games in the group stage,knockout 8)as the research object,using the literature material law,video analysis,logic analysis,independent sample t-test,correspondence analysis and regression analysis,the game of "breakthrough" and "ball","center","cut" and "roll" and "ball" that create a shot six and nine shots area were analyzed the results of the study are as follows:1.Offensive situations that change the team's possession during a game include half-court attack,fast break,and turnovers.And in the Olympic men's basketball competition,half-court position attack is the main way of the game attack.2.In this Olympic Games,there is a significant difference between the group stage and the knockout stage in holding the ball to create shooting opportunities;In the group stage and the knockout stage,the percentage of ball holding and shot creation is the highest,and the second and third place is to create shot opportunities and pick-and-roll chances.The percentage of breakthrough in the knockout stage is 20.90% higher than that in the group stage,19.51%,showing the importance of individual breakthrough ability of players in high-intensity and high-confrontation games.In the two series,the center position singles to create shot,cut to create shot,no ball cover to create shot opportunities are relatively small.3.In the men's basketball competition of the Olympic Games,there are significant differences between the "strong team"(top six teams)and "weak team"(bottom six teams)in three aspects: breaking through to create shooting opportunities,cutting to create shooting opportunities,and no ball covering to create shooting opportunities.The proportion of "holding","cutting" and "cutting" created by the strong team was higher than that of the weak team.The relatively high penetration rate of the weak team to create shooting opportunities and the position of the center in the singles to create shooting opportunities is more the individual player's attack,which also reflects another rule of basketball that is the individual can not win the final victory of the game;The shooting opportunity creation of this Olympic Games is a trend of the long distance shooting,the pick-and-roll shooting of two or three people and the personal breakthrough of the players,which is supplemented by the "single play of the center position","the player without the ball cover" and "the individual cutting attack".4.According to the corresponding analysis,China,venezuela and the United States have a strong correlation with breakthrough creation of shooting opportunities,among which the Chinese men's basketball team has the strongest correlation with breakthrough creation of shooting opportunities.The shots created by holding the ball are located in the "center" of the corresponding analysis chart,which indicates that most of the shots created from participating countries and holding the ball have a strong correlation.No shot creation and cut shot creation are at the edge of the scatterplot.5.In the men's basketball competition of the Olympic Games,the most frequent use of pick-and-roll to create shooting opportunities and breakthrough to create shooting opportunities in zone 7;Increased chances of shooting outside the three-point line in knockout games;The "strong team"(top six)and "weak team"(bottom six)have significant differences in the creation of shots in different areas,including zone 1,zone 2,zone 6 and zone 9.The 12 teams showed the highest percentage of total shots in the 7th district.Zone 1,zone 2 and zone 4 are the three areas with the highest offensive ratio of strong teams except 7,which are all within the three-point line.Zone 1 is closest to the basket,and zone 2 and zone 4 are symmetrical with each other.Most teams are good at creating shots in the end zone,the arc of the three-point line,and the left side of the three-point line.In the aspect of scoring rate,each team's performance is inconsistent,but most teams have higher scoring rate in the 1st,3rd and 4th districts,while the offensive efficiency in the 5th,8th and 9th districts is low.6.According to the regression analysis,the key factors influencing the final win rate of the men's basketball competition of this Olympic Games are "no ball" to create shooting opportunities,"hold ball" to create shooting opportunities,"cut" to create opportunities and "pick-and-roll" to create shooting opportunities.
