Why does badminton have a 21 point system?

The 21-point game is based on a 15-point system to explain the ball, and players often change serve many times in a row without scoring points, and the pace of the game is difficult to control.

It is specially changed to 21 points, scoring per ball.

The International Badminton Federation does not change the format for the sake of who is stronger, only for the sake of a fairer competition.

Make some adjustments to the game for the visual experience of the audience.

Changed to a 21-point system, eliminating the exchange of serve rights during the 15-point system, the pace of the game will be tighter.

1.Match Factors: Playing time is shortened, spectacle is improved, uncertainty is increased by ......

2.Commercial factors: Due to the long time of the badminton game under the 15-point system, sometimes a game will take about two hours, which will affect the advertising time, which makes many businesses lose money and be dissatisfied, but after changing to 21 points, the game time is more grasped, and there is enough and suitable time for advertising.

At that time, it was to control China's winning streak. And it's just to increase the viewing experience! The 21-point system is a point-per-ball system, so that the game is more intense.

The level can be played more comprehensively! It can also improve the viewing and promote TV broadcasting.

It's to make the game more intense, but the main thing is to limit us China, who called us so strong, haha.

Badminton game rules 11-point system, friends who like badminton are very familiar with the rules of badminton games, in the previous badminton games have been using the 21-point system, but recently the 11-point system has been adopted, let's learn about the badminton rules 11-point system.

5 games 3 wins, a single game 11 points, as long as you can get the 11th point in a single game, even if you win this game, that is, the player 11:10 can win a single game.

11-point badminton format:

best-of-three system; 11 goals per game, (goal difference 2);

If there is a 10:10 match, the extra game will be played until one side wins two goals first, first come, first served;

For example: 15:14 or 21:20;Another 11-point system: there are also 11 goals to win;

After a score of 1:1; 6 goals in the tiebreaker (5:5 will be added to the extra game, up to a maximum of 11 goals);

For example: play-off after 5:5; 7:5 wins; The maximum is: 11:10

This year's Tongyou Cup implements a 21-point system, and compared with the previous 15-point system, there are the following 5 changes:

1. Each set is played with 3 games, and the side that wins 2 games first wins, and all 5 individual games are 21 points per game, and the score per ball system is adopted; 2. The first to score 21 points in each game, and the side with an advantage of more than 2 points wins the game. If the two sides are tied at 20, the game continues until one side has a 2-point advantage. If the score of the two sides is tied at 29, the first team to score the 30th point wins; 3. When one of the first teams scores 11 points in each game, there will be a 1-minute technical timeout in the game; 4. In doubles, two serves are cancelled, and each side only has one chance to serve; 5. After the cancellation of the two serves, the serving position of the doubles match has changed greatly.

Under the 21-point system, at the beginning of each doubles game, the serving side is sent by the player from the right court area of the side to the player of the right court area of the opponent; If the serving team scores, the serving player continues to serve and changes the serving half, while the two players on the receiving side do not change positions; If the receiving team scores a point, the two sides exchange the serve, with the player in the right court serving if the team has an even number of points at the time, and the player in the left court if the score is an odd number at the time of the break.

The first advantage of the new format is that the game time is significantly shorter. In the past, once the Tongyou Cup was played for five or five games, the game usually lasted five or six hours.

The second advantage is that due to the predictability of the game time under the new format, the TV station will be able to know the broadcast schedule in mind, and the broadcast will not be interrupted again. In addition, there was a technical timeout at 11 minutes, which was very beneficial for the TV broadcast to attract advertisers. Attracting TV stations to broadcast games is one of the key factors for the survival and development of any sport.

The third advantage is that it narrows the gap between the "rich and the poor" in badminton, and the incompatibility of the game has increased significantly. At present, there are not many strong teams in the world badminton world, so it is very important to attract more badminton enthusiasts and countries and regions to actively participate in badminton.

The fourth advantage is that there are almost no badminton players who do not participate in the game without injuries, so how to avoid injuries has always been a topic of research for each team. The new format is less physically demanding on athletes, which is a protection for athletes and beneficial for them to prolong their athletic life.

The difference between the 21-point system and the 15-point system in the badminton game of foot ball:

1. The system of suing brothers is different. On a 15-point scale, the player who gets the ball is awarded a score, while on a 21-point system, either side can score points if either side hits the ball "to death" in the opponent's valid position, or because the opponent has made a violation or error.

2. The rules of serving are different. The 21-point system is a per-ball scoring system, that is, no matter which side serves, the winning side can score, while the 15-point system is a service system, that is, if one side serves and the opponent wins, the opponent cannot score and can only win the serve.

3. The suspension system is different. In a 21-point system, players are not allowed to interrupt the game, and there is a 1-minute technical timeout when one side leads by 11 points in each inning. In the 15-point system, players can ask the referee to stop the game during the game, wipe sweat, drink water or tie their shoes on the sidelines.

4. The bonus point competition system after the deuce is different. In a 21-point system, when each game is tied at 20, one side is considered to win the game if they are 2 points ahead, and if the two sides are tied at 29 and one side leads by 1 point, the game is won. In the 15-point system, when the two sides of the game are tied at 14, the side that scores 14 points first has the right to decide that both sides will score 3 more points.
