Research On The Technical Offensive And Defensive Characteristics Of NBA Excellent Center Positions

As the highest level representative of the world basketball league,Ba has become the benchmark of other basketball league in the competition,whether in the physical quality of players or the combination of personal skills and team tactics.With the development of the times,the technology of attack and defense position of the center has changed and developed greatly in shooting mode and area,passing and receiving technology,breakthrough technology,rebounding technology and blocking technology.In this paper,through the methods of literature,video observation and mathematical statistics,we study the change of attack and defense characteristics of nba2018-2019 and 2019-2020 regular season excellent center position technology,and draw the following conclusions:1.The shooting area of NBA excellent center presents the characteristics of expansion and balance,and the shooting form presents the characteristics of diversification.In the competition,the skill of shooting from one hand to shoulder,jump shot and moving shot has become the center's regular shooting skill,and the number of dunks is relatively large.The number of low position offensive shooting skill is gradually reduced in the competition.The three-point shooting is mainly in the area of far distance block or cover and catch shot,and the shooting area is mainly in the area of arc top and 45 degrees left and right The three-point shooting frequency in the corner area of left and right ends is less.2.The breakthrough area of NBA excellent center gradually covers the half court attack area,and the breakthrough technology has the new characteristics of routine and diversification.The excellent center mainly adopts the sudden acceleration and the same side step holding breakthrough after the basket dribbling on the high receiving surface,and the body forward changing breakthrough technology gradually becomes the routine breakthrough technology of the excellent center;the breakthrough timing mainly depends on the forced breakthrough and the breakthrough after the fake action,and the breakthrough times after the cover are relatively less.3.NBA excellent center passing technology mainly presents concealment,rapidity and accuracy,and the form of passing presents variability and uncertainty.In the passing technique,there are many times of passing between hands,hands on the head and hands at low hand after half turning,and the times of using the two hands chest passing technique in the game are greatly reduced;the times of transferring and moving the ball in the passing effect occupy the main position,but the times of assists are gradually close to the times of turning and moving the ball,which also shows that the excellent center has become the initiator and initiator of organizing the attack in the game The core of tactical implementation.4.The defense area of NBA's excellent center has been enlarged,covering the whole half of the court.Under basket and close area defense still occupy the main position in the game,and the number of medium and long distance defense is gradually close to the number of under basket and close area defense,mainly to prevent high-level block and cover.When the high and low dislocation defense is formed after the defense of high-level pick-up or cover,the shooting,passing and breakthrough of the attacking players are interfered,robbed or blocked by the moving ability and the high and low dislocation hard strength.5.In simultaneous interpreting,the NBA center has a downward trend in the number of backcourt rebounds compared with the traditional center.The number of rebounds has been gradually reduced and the number of rebounds has been increasing.6.NBA excellent center cover area gradually expanded from under the basket and close range area to the middle and far range area,with various cover methods.Under basket and close range areas are still the main areas of cover,and some middle and long range areas gradually generate cover times;excellent center is mainly to prevent breakthrough and follow-up cover,assist in defense and fill in post cover.7.The factors that affect the attacking and defending characteristics of NBA's excellent center position technology include the influence of game fairness,the influence of technical and tactical changes,the need of higher appreciation,and the need of external cultural expression.
