Investigation On That Match Characteristic Of The Non-ball Cover Of The Chinese And Foreign Men Basket At The 31st Olympic

The men's basketball game of the Rio Olympic Games fully demonstrates the changes and development of the world basketball game,the uneven development level of the world basketball game,the new features of the technical and tactical style,and the basketball team represented by the European and American countries is still in the world leading level.However,the failure of the Chinese men's basketball team in this Olympic Games not only reflects the gap between the Chinese men's basketball team and the European and American men's basketball team,but also reflects that the Chinese men's basketball team is facing unprecedented challenges.It is that purpose of this study to analyse the feature of the non-ball cover of men's basketball game at the 31 Olympic Games,and to find out the cause of the success of the ball without ball cover,and to find out the reason of the success or failure in the cooperation of the ballastle-free cover,so as to provide a theoretical reference for the Chinese men basket in the training and competition of the Chinese men basket,and to better serve the training and competition of the men basket.This study used the methods of literature,logic analysis and mathematical statistics to analyze the cooperation characteristics of non-ball screen in the Chinese and foreign men's basketball team at the Olympic Games in Rio,and carried out in-depth study on the combination of non-ball cover and the tactical effect of Chinese and foreign men's basketball.The main conclusions are as follows:1,The non-ball cover of Chinese and foreign men's basketball shows the following characteristics:(I)The non-ball cover time is concentrated in the 0-10 second period,and the non-ball cover shows a decreasing trend with the increase of offensive time;(2)The no-ball cover area is mainly on the free throw line and on both sides,followed by the restricted area.There is less non-ball cover outside the three-point line,and the area where the match occurs is transferred from the original low area to the free throw line and both sides.The non-ball cover outside the three-point line is mainly concentrated in the arc top and 45 ° on both sides;(3)The characteristics of the non-ball cover personnel combination are based on the non-ball cover cooperation between the center and the shooting guard,followed by the non-ball cover cooperation between the power forward and the shooting guard.Single cover is the main,double cover gradually increased;(4)The main way to coverthe team members is to pull them apart from the offensive mode,followed by internal removal,and there is less static and false cover;The covered team members first chose to pop up with the help of cover,followed by passing the ball,and chose the lowest offensive method of shooting;(5)In the form of non-ball cover,the following covers are the main ones,followed by cross-cover,non-ball cover with medium and double cover,Flash cover,and back cover.These three non-ball cover forms are relatively balanced,and the STS appears the least.;(6)In terms of the characteristics of the non-ball cover effect,the most indirect offensive benefits are obtained after the cover,and the proportion of the offensive baskets obtained directly is not large.After the non-ball cover,the shots scored more with two points,of which the main one was the mid-range shot.,followed by 3 points.The offensive has a strong emphasis on exterior lines.2,There is a gap in the use of Chinese and foreign men's basketball teams in the absence of ball cover: the cover timing of the Chinese men's basketball team is unreasonable,and the cooperation between players is not tacit;The spacing between the attacking players is too tight and can not reasonably use the space advantage;Single personnel mix,less change;After covering the player's cover,he did not go down or open in time.After the cover,there was a lack of diversity in the attack method;After the cover,the passing method is single and the passing time is poor;Double cover and continuous cover are used less and lack continuity.3,The non-ball cover tactical characteristics of the Chinese and foreign men's basketball teams: The non-ball cover is diversified,refined,and systematized,gradually achieving team participation and team cooperation;Pay more attention to the continuity and variability of cover cooperation.
