match
The volleyball competition venue is a rectangle of 18m× 9m, with at least 2m open space around and no obstacles at least 7m above the venue. Draw a line in the middle of the court and divide the court into two equal areas. All lines are 5 cm wide. There is a net on the center line of the site. The net is 1 m wide and 9.50m long, and it is hung on two posts outside the stadium. The height of women's net is 2.24 meters, and that of men's net is 2.43 meters. At the junction of the two ends of the net perpendicular to the sideline and the center line, there are 5 cm wide sign belts respectively, and a sign pole with a length of 1.80 m is connected to the outside of the sign belt. The circumference of the ball is 65 ~ 67 cm, the weight is 260 ~ 280 g, and the air pressure is 0.40 ~ 0.45 kg/cm2.
The volleyball match starts with a team serving on the right (1 position) in the back row, and then each team can touch the ball three times (excluding blocking). If the ball hits the ground, an obstacle or a player fouls, it is a dead ball, and the side that caused the dead ball scores a goal. Only when the server wins 1 ball will he get 1 point. If the server fouls, makes mistakes or the receiver wins 1, the receiver gains the right to serve, and its players must rotate 1 clockwise. Each team must win 15 points at least, and win 1 game only if it exceeds the other team by 2 points. The highest score in the first four games 17. When the score is 16: 16, the team with 17 points first wins. The official competition adopts the best of five games system, and the deciding game adopts the scoring system. After the first team scored 8 points, the two teams switched venues and continued the game to the finish line in the original position order. There was no highest score in the deciding game, and the game went on until the first team scored 2 points.
According to the rules, 1 team at most 12 players, 1 coach, assistant coach and doctor. Players' clothing must be uniform, and there are obvious numbers on the front and back of the coat. The coach can give guidance during time-out and intermission. Only the captain can ask the referee or ask for an explanation of the rules in the game. If the coach or team member behaves unethically, the referee will show a yellow card warning. If they commit a crime again, they will show a red card and punish the team for losing the right to serve or the opponent will get 1 point. If there are serious fouls such as insulting the referee or the opposing player, you will be disqualified from the game or the whole game. Before each game, the coach must give the position table of the playing line-up to the recorder or the second referee, and it cannot be changed. There are 6 people in each team, standing in two rows, from left to right. The front row is in positions 4, 3 and 2, and the rear row is in positions 5, 6 and 1. When serving, both players must stand in the designated position, otherwise they will be sentenced to lose the right to serve or the opposing team will score 1 point. When the game is a dead ball, the coach and captain can ask the referee for a time-out or substitution. Each pause shall not exceed 30 seconds. 1 match, each team can ask for two timeouts. 1 match, the number of substitutions for each team shall not exceed 6 times at most. The technical action requirements of the rules are as follows: ① Serve: Players who have the right to serve must take turns to serve first, and player 1 hits the ball within 3 seconds after the referee blows the whistle. After serving, if the ball touches the player, the net, the post or other obstacles on the server's court or crosses the net area, the ball falls out of the opponent's bounds or the serve does not enter the net, which is a service mistake and loses the right to serve. Before the team makes a mistake, the server serves continuously. ② Touching the ball: Players can touch the ball from any part of the body above the knee joint, but they are not allowed to stay. In case of catching, holding, pushing and throwing the ball, it is judged as holding the ball. Each team touches the ball at most three times (except blocking). If 1 player touches the ball continuously for more than 1 times (except blocking), it is judged as combo. Two players on the same team touch the ball twice at the same time. However, both players can hit the ball three times after touching the ball at the same time on the internet. (3) Offensive hitting: directly hitting the ball at the opponent's court is offensive hitting. Front row players can make offensive shots at any height on this field. The players in the back row can only hit the ball in the frontcourt in a way that the world is not higher than the upper edge of the net before the attack line, but they can hit the ball at any height when taking off behind the attack line. ④ Over the net: players are not allowed to hit the ball through the net, but the hitting point is in the court. After the ball leaves the hand, the hand with the ball over the net will not be judged as a net foul. Before the opponent hit the ball, the blocker touched the ball and crossed the opponent's court, and was convicted of a net foul. When the opposing team hits the ball, it is allowed to block the ball at the opposing court. ⑤ Crossing the center line: Any part of the player's body crosses the center line and touches the ground of the opponent's court, which is a foul on the center line. However, if one foot or part of both feet step on the center line and the other part steps on or above the center line, no foul will be awarded. Players can reach out and hit the ball under the net, but they must not interfere with the opposing players. ⑥ Blocking: Only players in the front row are allowed to block individually or collectively. In 1 block, the ball can continuously touch 1 or several pieces of hands, head or any part of the body above the waist, which is counted as 1 block. After blocking, the team can hit the ball three times. After the blocker touches the ball, the ball falls out of bounds and the tentacles are out of bounds. This is a mistake. A formal volleyball match should have 1 referee and 1 referee, 1 recorder and 2 ~ 4 linesmen.
