Basic content of rules

According to the above five basic principles, Mr. naismith worked out the most primitive rules of basketball match. There are 13 original basketball competition rules. The basic content of this 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. It is against rules 3 and 4 to hit the ball with fists. 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. Edit the basic rules of this competition 1

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 game is divided into two halves, each half is 20 minutes, and the intermission is 10 minutes. 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 dividing line and 1 point for free throws.

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.

After shooting, you can't cross the free throw line before the ball touches the basket.
