A preliminary understanding of basketball

(

According to these five basic principles, Mr. naismith made the most primitive rules of basketball match. The original rules of basketball match are 13. The basic content of article 13 is:

1. Players can throw the ball in any direction with one hand or both hands.

2. Players can catch the ball in any direction with one hand or both hands, but they must never hit the ball with their fists.

Players can't take the ball away.

You must hold the ball with your hand, but you are not allowed to kick the ball with your head and feet.

5. Players are not allowed to use shoulder bump, hand pull, hand push, hand bump, foot trip and other methods to deal with opposing players. Any player who violates this rule is regarded as the first foul and will be forced to stop playing until he hits the target. If you intentionally hurt the opposing player, you will be disqualified from participating in the whole game and will not be allowed to substitute.

6. hitting the ball with fists violates rules 3 and 4.

7. If either side fouls three times in a row, it is counted as the other side's goal. Continuous foul refers to: during a period of time, the opposing team members did not foul, while their own team members fouled continuously.

8. If the defender doesn't touch or interfere with the ball, when the ball is thrown into the basket and stays in it, it is considered a basket. If the ball stops at the basket and the other team touches the basket, it is also a fortune teller.

9. When the ball is out of bounds, the ball will be thrown into the field by the first person who touches it. If there is an argument, the referee will throw the ball into the field. Throw a foul ball for five seconds. After more than 5 seconds, the ball was awarded to the opponent.

10. The referee is the referee of the player, and he has the right to call a foul. When a team fouls three times in a row, he will notify the assistant referee. He has the right to declare an athlete disqualified.

1 1. The assistant referee is the referee of this ball. He can decide the time of the ball in the game, he should count the time, decide the stroke of the ball, record the number of strokes of the ball, and bear the responsibility that the referee should bear at ordinary times.

12. The game will be played in two 15 minutes with a 5-minute break.

13. The team that hits the ball the most wins. If there is a draw, with the consent of both captains, the game can be postponed until another goal is scored.

Although the original 13 basketball competition rules are not systematic and complete, and some terms are not clear enough, they have played a great role in promoting the development of basketball in the early stage. In particular, basketball has developed into a modern basketball sport today, and the technical and tactical level is getting higher and higher, so the rules are even more important. It requires strict, scientific and systematic management of basketball games.

Rule number one:

1. Competition method

There are five people in a team, one of whom is the captain and at most seven substitutes, but the number can be increased according to the organizer. The competition is divided into four stages, each stage is 10 minute, with a 5-minute intermission and 10 minute intermission. At the end of the game, if the two teams have the same points, overtime will be played for 5 minutes. If the score is still the same after 5 minutes, a 5-minute overtime will be played again until the tie is broken.

2. Fraction type

After the ball is thrown into the basket and approved by the referee, it is counted as a score. 3 points can be scored for the inner input of the branch line; You can get 3 points for shooting outside the three-point line, and the penalty 1 point.

3. Way of proceeding

At the beginning of the game, each team pushes a jumper to the central jumper area, the referee throws the ball, and the jumpers from both sides start the game. Throw a foul ball.

4. Player replacement

The substitution of each player should be completed within 20 seconds, and the number of substitutions is unlimited. The time to exchange players is when someone fouls, fights for the ball, calls a timeout, etc. The referee can temporarily suspend the timing of the game.

5. Free throw

Each player has four chances to be allowed to foul, and the fifth time is all out (6 times in NBA). And cannot be played again in the same game. Free throw is shooting when no one can stop or defend it. It is a punishment for the offending party and an opportunity for the opposing party. Stand behind the free throw line and shoot within 10 second after receiving the referee's ball. After shooting, you can't cross the free throw line before the ball touches the basket.

lawbreaking

It can be roughly divided into (1) common violations, such as walking with the ball, dribbling twice, kicking the ball or hitting the ball with your fist. (2) jump ball violation, (3) jump ball violation: before the jumper touches the ball, people other than the jumper are allowed to enter the central area of the jump ball.

Rule number two:

24-second rule

-The attacker must make a shot within 24 seconds when he is in possession of the ball on the court (24 seconds in NBA, CBA, CUBA and WNBA ... 35 seconds in NCAA).

10 second rule

-The team must control the ball from the backcourt and make the ball enter the frontcourt (the opposing half) within 8 seconds.

Five-second rule

-After holding the ball, the player must throw the foul ball within 5 seconds. FIBA rules stipulate that free throws must also be made within 5 seconds.

3-second rule

-Divided into 3-second attack and 3-second defense. Attack for 3 seconds: the attacking player shall not stay in the 3-second zone for more than 3 seconds; Defend for 3 seconds: When the opponent of the defender is not in the 3-second zone or on the edge of the 3-second zone and completely gets rid of the defender, the defender shall not stay in the penalty area for more than 3 seconds.

personal foul

-foul caused by physical contact with the other party.

technical foul

-A player or coach is fouled for poor performance, such as an argument with the referee.

Disqualification foul

-The player made a foul action that did not reflect the sportsmanship, such as hitting someone. When this happens, the player should be sent off immediately.

Five fouls by athletes

-No matter personal or technical fouls, players must leave the field for a total of 5 fouls (6 according to NBA regulations) and are not allowed to play any more games.

Contrary to the usual practice

-Violation of rules that are neither personal nor technical. The main violations are: illegal dribbling; Take the ball away; 3 seconds violation; Get the ball out of bounds.

Team member out of bounds

-When the player touches the boundary or out-of-line area with the ball or the ball itself, the ball is out of bounds. The ball doesn't go out of bounds in the air until it hits the line or out of line.

Interference ball interferes with shooting score (present participle form of goal)

-When the shot ball falls to the basket, neither player can touch the ball. Defenders can't touch the ball when it is under the basket.

-After the ball lands, the opponent must not touch the ball until it lands.

High-profile athletes

-The player closely watched by the defender must pass, dribble or shoot within 5 seconds, otherwise his team will lose possession of the ball (which is not stipulated in NBA rules).

The ball returned to the backcourt.

-If the team has moved the ball from the backcourt to the frontcourt, the players of the team can no longer move the ball across the center line and transport it back to the backcourt.

Introduction to the main location of basketball court

Point guard (PG) (West Base)

The point guard has the most chances to get the ball on the court. He wants to bring the ball safely from the backcourt to the frontcourt, and then pass it to other teammates so that others can score. A qualified point guard must be able to pass the ball across the half court without any problem when only one person is defending. Then, he must have good passing ability, and he can pass the ball where it should go most of the time: sometimes it is a gap in shooting, and sometimes it is a better guide. Simply put, he wants to make the ball smooth, and he wants to be able to pass the ball to the place where it is easiest to score. Furthermore, he should organize his own team's attack and make his teammates' attack more smooth.

There are other requirements for the point guard. In terms of scoring, the player who controls the ball is often the team's last scorer, which means that unless other teammates don't have a good chance to shoot, he won't shoot easily. Or to put it another way, his scoring ability is very strong. He uses his scoring ability to destroy the opponent's defense and create opportunities for his teammates. In short, there is an unchangeable principle for the point player: if any teammate has a better chance to play on the spot than him, he will definitely give the ball to the teammate with a better chance.

Shooting guard (SG) (Coltat West)

The shooting guard takes scoring as his main task. He is the second leading scorer in the field after the small forward, but he doesn't need to practice singles skills like the small forward because his teammates often help him find a gap and shoot. However, because of this, his outside accuracy and stability should be very good.

Shooting guards often have to do two things. First, there is a good gap to shoot the outside line, so his outside line must be accurate and stable. Otherwise, if teammates try their best to block a good opportunity but fail to score, it will do a great blow to the morale and confidence of the whole team. The second is to find a small gap to throw an outside line, so he has to be quick. A good shooting guard can't expect such a good gap every time. He should be able to find shooting opportunities in a short time, and his shooting percentage should be at a certain level. This can stall the enemy's defense, and the defensive circle must be opened, which is more conducive to teammates' attack in the restricted area.

Small Forward (Small Forward) (West Alero)

Small forward is the team's most important scorer. The most fundamental requirement for a small forward is to score, and it is a long-distance score. As soon as the small forward receives the ball, his first thought is how to put the ball into the basket. He may rebound, but it is not necessary; He may pass the ball well, but it is not necessary; He may bounce well, but it's still unnecessary; He may defend well, but it's still unnecessary. The basic job of a small forward is to score, score and score again.

Small forward is the position with the lowest requirement for shooting percentage. Generally speaking, as long as 45% is qualified, more than 40% is acceptable. Of course, there is a premise that he wants to score goals. If a small forward averages seven or eight points per game and hits only 40%, it is better to let him sit on the bench. On the other hand, why can the shooting percentage of small forwards be lower? Because he is the main scorer in the team, he often has to take the initiative to look for opportunities to shoot, stabilize the morale of the army at some moments, and even boost morale by singling out opponents in more difficult ways, and even give opponents a fright and a head-on blow. So the small forward will have more chances to shoot, or it may be a bad chance, so we can allow him to play lower, as long as he can score.

Power forward (PF) (Siala-fulcrum)

The task of power forward in the team is almost always very hard. Rebound, defense and blocking are all indispensable to him, but he is often the last to score. So power forward can be regarded as the most inconspicuous role on the basketball court.

The first job of power forward is to rebound. Power forward is usually the person who rebounds the most on the team. He is stuck in the penalty area, cooperates with the center and often provokes the rebounding task of the whole team. When attacking, he often helps his teammates to block people, and then tries to squeeze in to grab rebounds and carry out the second wave of attack after his teammates shoot.

Generally speaking, power forwards rarely shoot, and their shooting positions are often close to the basket, which requires higher shooting percentage. In terms of five positions on the court, power forward should be the one with the highest hit rate, and a good power forward should reach more than 55%. But because scoring is not his strong point, he can score few points, but he must grab more rebounds. In addition, Hotpot's defensive ability is naturally necessary for power forward, because he wants to consolidate the restricted area, and defense is of course important. In fact, power forward is to do two things well: rebounding and defense.

Center (c) (west axis)

As the name implies, the center is the core of a team. He spends most of his time selling labor and figures in the restricted area. He is offensive and defensive, and is the hub of the team, so he is called the center.

What will the center do? First of all, since he lives in the restricted area, 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.

A good center needs versatility. 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 keep 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 the 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 the outside shooting can pull the opposing center out, 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.
