What are the restrictions on serving in tennis

1.Pre-tee rules.

The server should stand in the area behind the end line, between the midpoint and the putative extension of the sideline, and toss the ball with his hand in any direction in the air before serving, hitting the ball with a racket before the ball touches the ground (players with only one hand can use a racket to toss the ball). When the racket makes contact with the ball, the ball is sent.

2.Rules on the serve.

The server is not allowed to change the position of the original station by walking or running during the entire service action, and the two feet are only allowed to stand in the specified position and not touch other areas.

3.The position of the server.

1) At the beginning of each game, serve from the end line of the right area, and after scoring or losing a point, you should switch to the left area to serve.

2) The ball sent should pass over the net and land on the opposite corner of the opponent's teeing area, or on the line around it.

4.Error on serve.

Missed ball; The ball is sent out and touches a fixed object before hitting the ground (except for the net, center belt and white cloth on the edge of the net); Violation of the service position rules. After the first service error of the server, the second serve should be made in the original position.

5.The serve is invalid.

After the serve touches the net, it still falls into the opponent's service area, and the receiver is not ready to receive the ball; Both should be re-served.

You may be talking about the player's serve touching the net, because there is a sensor on the net, it can feel the change of the big net, once the net changes beyond a certain range, then the referee will think that the player's serve touched the net.

The serve should be sent to the box with the low net.

There are two situations in which the serve is invalid in tennis: after the serve touches the net, it still falls into the opponent's service area, that is, the referee in the game calls for wiping the net; The receiver is not ready to receive the ball.

The chief referee must be proficient in the rules of the competition and the rules of application, and have the right to interpret and deal with all issues such as the rules and procedures of the competition, the code of conduct and the rules of tennis that arise in the course of the game, and must be fully responsible for the actions he takes.

Arrange training and learning in advance before the game, so that all referees have a comprehensive understanding of the rules and procedures of the game, designate the referee team leader and arrange the referee and lineman of each game.

The serve does not go into the area, the serve wipes the net, and the foot crosses the baseline when serving. That's all I know.

Effective serve in tennis: 1. Rules before serving Before serving, the serving player should first stand in the area behind the end line, between the midpoint and the putative extension of the sideline, throw the ball in any direction in the air with his hand, and hit the ball with a racket before the ball falls to the ground (players who can only use one hand can use the racket). When the ball touches the racket, the serve is complete.

2. Serving Procedure A When serving, the serving player should start from the right half of the court in each game and stand behind the right half of the court in rotation to serve. If the serve is taken from the wrong half and the destruction is not detected, then the result of the match caused by the wrong serve will be valid. However, once this incorrect position is disturbed by the hair stool, it should be corrected immediately.

The ball sent by b should cross the net, touch the ground in the opponent's teeing area before receiving the player, or land on any line that constitutes the teeing area.

According to the hitting point from high to low or active to passive, it is divided into pounce, push, rub, hook, release, and pick.

I've said so much to you, but I want to remind you that the ones in your hands are very difficult to practice, and they require precision, if your pace is not good, no matter how good the skills in your hands are, they will be dished. So you should start with the simplest pace first, and you don't have to bounce the ball too much. It will be of great help to you.

Times. Times.

Correct answer: 2 times.

In tennis, the serve is usually delayed, and it is said to be twice. If you make a mistake, make a mistake, make a mistake, and make a mistake, you will know the opponent's Oak score.
