Volleyball originated in America. 1895, Massachusetts, USA, tried basketball flying in the air for the first time on the court, and named it volley ball, which means "flying ball in the air". It was not included in the competition at that time, but used as a game. At first, there was no uniform regulation on the number and position of players on both sides of the sub-station, so it was named "volleyball". Later, after several reforms, 16 was changed to 12 with 9 players. It was not until 19 18 that six competition systems and the rules of 15 scoring system were stipulated in volleyball matches. 1947 The International Volleyball Federation was formally established. 1964 Volleyball was listed as an official event of 18 Olympic Games. The volleyball court is18m long and 9m wide, and the middle of the court is separated by a net. The volleyball match is divided into two teams, each with 6 players, arranged in front of each other. According to the rules of the game, both sides use various techniques and tactics to try to hit the ball into the other side's court without making it fall into their own court. Players must return the ball from the opponent in the air, and each side will hit the ball at the opponent at most 3 times (excluding 1 blocking tentacle); It is impossible for a person to hit the ball twice in a row except for blocking the tentacles. If you can't hit back or hold the ball, combo, touch the net, etc. This is a foul. The opponent should be awarded a score or get the right to serve. There is no limit to the time of each game in volleyball competition, and the best of five games is adopted. The player who wins first in each game 1 15 points. In case both sides get 14 points, one side must get 2 points to win. At present, the techniques and tactics of international volleyball are developing rapidly. For example, the fast and flexible offensive tactics represented by China and Japan enjoy a high reputation in international volleyball and play a positive role in promoting the development of volleyball tactics. In recent years, more advanced offensive tactics such as "short and fast", "flat open", "time difference" and "dislocation" have appeared, with changeable tactics, faster and faster speed, flexibility and comprehensive technology. Volleyball has been included in men's and women's competitions since 1965 18 Olympic Games.
