The normal situation is that the ball can only be changed when it is broken. The referee looks very carefully, the front, the back, the side, turn over and over, that is, to see whether the ball is broken, there is no strict standard, only the referee thinks the ball is broken can be changed.
Because badminton cannot be exactly the same, there are subtle differences, sometimes the side that has lost a few balls in a row will feel that the badminton used is not good, such as easy to hit the boundary or easy to hang the net, so when the ball is not obviously damaged, it will ask to change the ball, and at the same time can destroy the momentum of the opponent's continuous scoring.
For the side that scores consecutive points, this ball is very easy to use and helps to score, so it often refuses to change the ball. If there is no obvious damage to the appearance of the ball, such as a damaged feather or a loose base, the referee will refuse to change the ball, also for the sake of fairness.
-
This is usually the case when a player makes multiple changes in a row. Another game ball is very expensive. The cost of one is also before 5 to 8 blocks. Sponsors usually ask referees to make fewer substitutions.
-
Because one wants to change and the other disagrees, it is all out of tactical needs, so the referee should be fair.
-
In the case that the badminton does not affect the game, it is not allowed to change, and people have their own feelings when playing, and if the ball does not go well, it is considered a problem with the ball, which is also a tactic, and the referee must judge whether the ball can be changed according to the standard.
-
The referee will carefully check whether the feather leaf is broken, as subtle changes can affect the speed and trajectory of the ball. The most important thing is to see if the badminton can be replaced if it is damaged.
-
In general, as long as one party asks to change the ball and the other party agrees, the referee does not care, but one party does not agree to change, then the referee needs to see whether the ball has hair loss and deformation and decides whether to change the ball.
-
Don't let players change the ball to disrupt the rhythm of the opponent or the game, or delay the time
-
Prevent players from deliberately delaying time. Just a tactic.
-
The main thing is to prevent some players from deliberately delaying the game.
-
The first is to prevent the player from deliberately delaying or interrupting the game due to a change of ball, and the second is to prevent the player from deliberately changing the shape of the ball or damaging the ball. Thank you.

Don't let players deliberately delay the game.

The purpose of changing the ball is to adjust the nervousness, and after the shuttlecock is damaged, it will affect the flight speed and angle of the ball, and affect the level of the player.
Men's Doubles is the most frequent match for ball changes.
From a professional point of view, some slight damage and damage to the badminton will not affect the flight speed and angle of the ball, and affect the level of the athlete.
On the other hand, when a feather breaks or falls off, the ball slows down and spins like a ballet, affecting the angle and strength. Therefore, the substitution of the ball is to ensure the normal performance of the players.
-
On the one hand, the ball itself has been damaged, such as the feathers on the ball falling, which will have a great impact on the performance of the players;
On the other hand, it is the player who wants to take advantage of the gap between the ball changes to make the body relax for a short time and think about the next step of play.
However, now that the new regulations have come out, players must get the consent of the referee to change the ball, and they cannot change the ball at will if they do not agree.

Badminton referees have different division of labor, which is generally divided into: arbitration (usually only Chinese games will be set up, and the number of people is generally singular), referee (referee), deputy referee (deputy referee), chief choreographer, chief recorder, recorder, recorder (umpire), service judge (service judge), line judge (line judge), the above are collectively referred to as technical **. There is also a medical officer (the race doctor).
In large-scale competitions, the general on-the-spot referees are divided into: chief referee, serving referee, and lineman. Nowadays, it is rare to see a scorer, because the referee uses the electronic touch screen to connect the display to directly display and present the score to the audience in time.
International competitions now also have Hawkeye replay technology**, which is generally held by referees from third countries who do not have the task of playing in the quarter.
In major competitions, a game is fully arranged: 1 referee, 1 serving referee, 10 linemen, a total of 12 people. It is known that in unimportant games, the number of linemen will be relatively reduced, and the task of reducing linemen will be borne by the referee.
In the amateur games we usually see, there is usually a one-man system, and there is only one referee who is responsible for all the tasks on the field.
Hope mine is helpful to you.

The change of the ball is mostly to adjust the yard, but there is no tension.
When the shuttlecock is damaged, it will affect the speed and angle of the ball, and affect the level of the player.
Men's Doubles is the most frequent match for ball changes.
From a professional point of view, the badminton is slightly broken.
And after the injury, it will not affect the flight speed and angle of the ball, affecting the level of the sports mountain scale. But on the contrary, there is a break or a drop.
When the whole feather falls, the ball slows down, like a ballet.
Dancing like a whirl (if you are interested, you can try it yourself, sense.)
It's weird), and it affects the angle and dynamics. Hence the change of ball.
It is to ensure the normal performance of the players.

Because it's a meticulous thing.
1. There are many rules to grasp in the serve, such as not being able to cross the waist, passing the hand, touching the midline and moving under the feet, and off the ground, so there must be a referee who is specifically responsible for serving - the deputy referee.
2. In addition to being responsible for the core things on the court, the referee should also be responsible for the players who receive the ball.
3. Whether the serve is wrong (because it is a diagonal.
There should be a referee in charge of the middle line referee.
4. For whether the ball is out of the bottom line, there must be a bottom line referee on both sides.
5. For whether the ball is out of the sideline, there must be 2 sideline referees on both sides.
6. For whether the ball enters the service area before the net, there must be a front service line referee on both sides.
7. In addition to these, the referee shall be responsible for the overall appeal and mediation work in each game.
A maximum of 11 referees for a badminton game! I hope you are satisfied.
The change of the ball is mostly to adjust the tension.

The referees are divided into the main referee, the serving referee, and the lineman. The referee and the serving referee are located on either side of the net. >>>More
The head of the shuttlecock is heavier, and it can gain greater inertia when it is hit, so that the shuttlecock can fly for a long time, and the feathers at the tail of the shuttlecock are used to stabilize the direction of flight. When you hit the shuttlecock, the head of the shuttlecock gains a large inertia, the flight speed is large, and the tail inertia is small, and because the tail is designed to be an open shape that grows larger and larger backwards, the air resistance is large, and the flight speed is slow, so when it is beaten, it will turn around.
1. Prepare for the serve.
To improve the quality of your return, you must first have the right preparation posture. >>>More
1. Badminton forehand net front straight line back court footwork: after the forehand is put on the net, the center of gravity is retracted to the left foot, the right foot pushes hard to retreat one step, the left heel retreats one step, the left foot touches the ground, the heel is lifted, with the left forefoot as the axis, turn the hip to the right so that the body is side to the net, and then retreat to the back court with parallel or cross step footwork. In the last step, jump up with your right foot when you land, and then hit the ball after completing the twist in the air, landing with your right foot in front and your left foot back in the ground. >>>More
