What are the main functions of a basketball center and what are the criteria for choosing a center? Thank you for your questions.

Center, as its name implies, is the core of a team. A position on the basketball team; Generally, it is played by the tallest player in the team, which traditionally emphasizes the protection of the basket defense and defensive cricket. Some center players with offensive talent often become the main point of shooting near the restricted area because of their height advantage. Although there is no fixed "height standard" for the center, the height of the center for men's basketball is generally above 2m 08(6y feet 10 inch), and that of the center for women's basketball is generally above 1m 90(6 feet 3 inches). In technical statistics, the center can usually contribute the most blocked shots and often achieve high shooting percentage and rebounding performance. Because the number of basketball players who can reach more than 2m 13 (7ft) and still maintain good athletic ability is limited, a few centers with both height and flexibility can often become an important factor in winning or losing the game. Take NBA as an example, a center with athletic talent, spirit, skill and good physique is often the key to a strong team. First of all, he is active in the restricted area, and rebounding is absolutely indispensable. Again, the restricted area is a battleground for all teams. Of course, opponents can't attack it easily, so the ability to block attacks and build hot pot is also indispensable. When attacking, the center often has the opportunity to stand in the penalty area near the free throw line (which is the center of the whole attack field) to catch the ball. At this time, he should also have good ball guiding ability and send the ball to a more suitable corner. The above three items are the basic skills that a center should have. In the team, the center is often responsible for scoring. He is the main inside scorer, corresponding to the inside and outside small forward. Because he wants to play singles, his shooting percentage can be lower, but his hand is often closer to the basket, so his shooting percentage is higher. Generally speaking, 52% can be used as a standard. The requirement of center's hit rate is second only to that of power forward. Technology needs a good center to be versatile. In attack, the center should have the ability to play singles near the basket, and he should be able to play singles with his back to the basket. Turning shot is the most common one, while jumping and hooking are more difficult to defend. Defensively, to be a good center, you should not only defend the players you should watch, but also help your teammates defend in time. To put it simply, if an enemy player bypasses his teammates' defense and enters the basket, the center should have the courage to make peace, while one person guards and defends his own restricted area. Of course, it doesn't mean that you can't leak it every time, but you always have the ability to "help". If a center can only hold his own people, it is not enough (unless the opponent is a super offensive center). There is a deformation of the center, which is called the outer center. The difference between him and a normal center is that his attack is mainly to shoot outside shots, and less to do singles in the restricted area. Because the center is tall, other short people can't keep it at all, so outside shooting can pull out the opposing center, so it is also very useful when the striker is strong. When defending, just like the average center, defend the opposing center and rebound as usual. Okur of the Jazz is an example. The representatives of many top teams in history are based on the top center players in the league, such as 1960s Boston Celtics and bill russell's contemporary wilt chamberlain, 1980s Lakers and Karim Abdel-Jabbar. Today, shaquille o'neal of the Boston Celtics (who once led the Lakers to win three championship rings) is also famous for his huge body (2 meters tall, 1 6,7 feet,1inch; Weighing more than 300 kilograms) and making good use of physical advantage skills, it poses a great threat to opponents in the restricted area, thus leading three different teams to the NBA finals. In today's international basketball and professional leagues, center and power forward are often played by players with similar conditions or given similar tasks, which is difficult to distinguish clearly. Basic skills that a basketball center should possess. In recent years, the center players have become more and more vague and close to the power forward, but the power forward seems to have some skills as a center. This is the trend that modern basketball players have more than one person or more people engaged in one position. Get rid of these trends of the times, only from the technical point of view of the center player, we must master some abilities: first, defense and rebounding: in the traditional basketball field, the center can not attack, but he must master the whole inside line in defense. As the last line of defense in the restricted area, the center needs to be able to defend the attack of the attacking center alone, and also need to make up the position when teammates miss the peripheral players of the other side. It is necessary to defend the opposing center and make up the defense. The technical requirements of these two tasks are that the center player must be quite experienced in judging the final position of the opponent's attack, and need fast movement and skilled standing skills. If the average pressure of hand defenders is 1, then the defensive pressure of center players is above 1.5. Only center players with skillful defensive skills can guarantee that the number of fouls will not rise too fast. Second, back to the basket attack skills: In traditional basketball, a major feature of center and power forward is the different attack methods. There are many attacks on the basket after the power forward catches the ball and returns to the basket, while the center pays more attention to the technique of using his height and weight to return to the basket to suppress his opponent. It is precisely because the pace of the center player can match the height and weight that the offensive action of the center player is rarely blocked. The so-called "back to the basket" these three words, put into the court, on behalf of the stage back to the basket into the restricted area to turn and shoot skills; Small hook skill of dribbling in the middle; And in the process of dribbling, you will find the passing skills of your peripheral teammates as soon as you are double-teamed by the defensive team; Third, the ability of high position: among the traditional basketball center players, we can often see the phenomenon of standing on a high post to catch the ball. For the center, if he has the ability of high position, he can attract the big defender to the free throw line, which will help his teammates run into the penalty area without the ball and will not be disturbed by the block. The center's high position ability is a necessary skill for the opponent to shoot directly when he can't defend the outside line after receiving the inside ball. Only a solid shooting technique can ensure high containment; Long-distance passing skills: Because the center is often the player closest to the basket in defensive tactics, he has more opportunities to get rebounds than the average player. Most center players are the tallest and heaviest on the court, which makes his vision relatively dominant. After the center player grabbed the rebound, he immediately paid attention to whether his teammates launched a fast break without the ball to the other half. If the opponent already has a teammate at half-time, he needs the center player to directly transfer the distance of the player to the frontcourt teammate instead of giving it to the point guard in an instant. Therefore, long pass penetration is also one of the indispensable skills for center players. Basketball court, ever-changing, center is no longer a noun of a specific player, but a synonym for skills and tactics. However, the above basic skills are essential, so we should be prepared to use the center's ability and complete the role of the center. Basketball center skills Basketball center skills: The center is the core of a team. With their strong and tall bodies, they are the key buttons of the team, whether attacking or defending, so they are called centers. As the "Optimus Prime" in the restricted area, rebounding is an indispensable ability of the center. In addition, blocking attack and blocking are also necessary abilities for the center. Because our team is often in the pivotal position in the center of the restricted area when attacking, the center should have good ball guiding ability, and can transport the ball to a more suitable position to help teammates score. The above three items are the basic skills that a center should have. Of course, scoring is also the responsibility of the center. They are the main inside scorers. The center should have a higher hit rate than the power forward. A good center must be versatile. He should not only have enough offensive and scoring skills, but also be the last barrier of the team when defending. In addition to defending the players he defends, the center should be able to coordinate and make up for the defense of his teammates in time. There is a new center tactic in modern basketball, the so-called "outside center". This kind of center needs to score mainly from the outside line and less from the restricted area when attacking. Because the defensive body is much worse than other players, the effect is not good, and the defender can only let the center of his team go to the outside line to stare at the opponent. In this way, the attacker can take advantage of the opportunity that the other center is not in the penalty area, so that the team's capable striker or defender can score crazy. Of course, "perimeter center" is only suitable for offense, and defense is no different from general center. The center shot backward in situ. 1. Application opportunities: 1. When the center player catches the ball with his back to the basket, he can shoot directly back when he meets the opponent's strict defense; 2. When the center player holds the ball with his hands back to the basket, he can choose to shoot backward in the same place when he has already used turn shooting or step hook shooting. 3. When the center player holds the ball with his back to the basket, he can combine fake actions, such as using the upper body to swing from side to side or turn around to confuse the opponent, and carrying the basket on his back. Second, the action method: (Take the back to the basket as an example) After receiving the pass from the partner, the center player opens his feet back and forth or left and right, and his knees are slightly bent. When the opposing team members are close to the back to defend, the elbows naturally catch the ball and sag. Look at the midpoint of your basket, stretch your arms back and forth, and throw the ball evenly with your hands. Third, technical points: the center player should feel the opponent's defensive situation with his back, look at his own basket (assuming that two baskets are a line), measure his own shooting strength according to the distance and angle of the opponent's basket, and determine the arc. When shooting, your hands should be even and your body should be coordinated. Advantages: the action is easy to learn, the hand is sudden, the hand is hidden and difficult to stop, and the opponent is hard to prevent. It is an extremely aggressive technique of "fighting big with small" and "controlling big with spirit". V. Disadvantages: The shooting percentage is not as high as that of frontal or lateral shooting. Need to consciously strengthen training. Center players should pay attention to the cooperation with their partners after catching the ball with their backs to the basket, look for offensive opportunities and means, and never shoot blindly with their backs in order to express themselves. However, I believe that "practice makes perfect, practice makes perfect", so we should try the technique of shooting backward to the basket. Several action essentials and precautions of the center 1 Backhand shooting action method: Take the bottom line on the right side of the basket as an example. Footwork is the same as one-handed shoulder shooting to the basket. The first step is to be bigger, and the second step is to take off and control the momentum. At the same time, the upper body leans back slightly, looks up at the basket, and lifts the ball directly from the chest to the basket. When the right arm is about to straighten, the wrist is twisted inward in the direction of the little finger, and the ball is plucked with the little finger, ring finger, middle finger and forefinger to make the ball rotate sideways and hit the board to shoot. 2. Hook shooting method: Take the athlete's right hand shooting as an example. His right foot reached out to catch the ball, and at the same time, he pushed the ball hard. Then take a big step towards the basket with your left foot, drop your center of gravity and tilt your upper body to the left. Take off with your left foot and bend your right leg. He held the ball in his right hand in an arc from his chest to his side and lifted it over his head to the highest point. At the same time, he can make the ball hit the board with the strength of his wrist and fingers. Action points: take off vertically with both feet, relax the balance in the air, hold the ball head firmly and grasp the opportunity skillfully. Block the attacker's shot or layup. When he lifts the ball to the highest point or the ball just leaves his hand, the defender immediately jumps up and knocks it down. This is called "blocking the ball". Blocking action method before blocking, the center of gravity should be lowered, the favorable position should be selected, and the short action should be used to take off quickly. When blocking shots, judge the time when the opponent takes off and shoots. When the opponent takes off and shoots, the defender immediately follows, and his body and arms are fully extended. When the opponent lifts the ball to the highest point or just shoots it, quickly use the wrist and finger strength near the opponent to dial the ball sideways or forward. 4. Blocking practice during dribbling and layup. The attacker stands on the sideline of the free throw extension line, one defends in front of the basket, the attacker dribbles and lays the basket, and the defender moves his position to seize the opportunity to take off and block. After shooting, the attacker passed the ball to the next player. After the defender practices blocking for one round in a row, another person practices. Requirements: judge the opponent's starting point before blocking, move and jump in time, stretch your arm upward to save the ball when blocking, or interfere with the pitching arc to avoid foul caused by physical contact. 5. In-situ blocking practice is a group of two people, one to one. The attacker can jump shot in place or take a step to block the jump shot. The defender judges the action of the attacker, and when the opponent takes off and shoots, the defender raises his hand in time to block the interference. After practicing several times, exchange offense and defense. Requirements: the defense should grasp the opponent's coming time, the blocking action should be extended, the action should be light and sudden.
