What are the requirements for playing football?

Endurance is a widely used technical term. In football matches, players often experience local muscle fatigue or general fatigue due to the huge demand for physical energy in a short period of time. Speed ​​is required, and now strikers are very demanding. It consists of the player's reaction to stimuli, the ability to make rapid explosive movements and the body's ability to keep moving quickly. Among them, acceleration is very important, and factors such as force effect and expected results should not be ignored. Strength refers to the ability of muscles to produce maximum force when contracting. In competition, players rarely use maximum force or rely purely on strength. However, good and comprehensive strength quality is undoubtedly very beneficial to the player's performance in the game. If speed is equal to distance divided by time, then explosive power is the product of speed multiplied by strength. In addition, good quality football shoes can also provide players with maximum bounce and adhesion.

Some basic knowledge of football

1. Number of players: In a soccer match, each team sends 11 players to the field (including the goalkeeper), for a total of 22 players. There are also three referees.

2. A football match lasts 45 minutes each in the first and second halves, and the total duration of the full match is 90 minutes. There is a 15-minute break between the first and second halves. Football matches can have extra time to make up for lost time, but in principle, the maximum extra time should not exceed 5 minutes.

3. If the two sides still cannot decide the winner after the full match, they can play overtime. The overtime is 30 minutes in total, divided into the first and second halves, each half is 15 minutes, there is no break in between, and the game starts directly after the change of sides. If there is still a partial winner in the overtime, it will enter a penalty shootout. The penalty shootout is divided into 5 rounds, and the team with more goals wins. If there is still a winner after five rounds, it will enter a single round to decide the winner until the winner is decided.

4. A penalty kick is when an opposing player is fouled, tripped, or has a handball in the penalty area. At this time, the opposing player takes a penalty kick at the penalty spot.

5. A corner kick is when the opponent's player kicks the ball out of or touches the opponent's half of the bottom line. At this time, the team's team takes a corner kick within the corner flagpole of the opponent's half of the bottom line.

Football originated in the State of Qi during the Warring States Period in ancient China. At that time, football was called "Cuju". In the Han Dynasty, Cuju was a means of training soldiers, and a relatively complete system was established. For example, a special court was set up, which was stipulated to be a rectangular east-west direction, with six symmetrical "Ju domains" or "Ju rooms" at each end, each guarded by one person. There were walls around the field. The game was divided into two teams, with each team attacking and defending, and the winner was determined by the number of times the ball was kicked into the other team's Ju room.

The rules of football

1. A football match is divided into two halves, each lasting 45 minutes, with a break of no more than 15 minutes. Overtime lasts 15 minutes per half.

2. Each team may not have more than 11 players on the field, including a goalkeeper. If a team has less than 7 players on the field, the game cannot start. During the game, the positions of the goalkeeper and other players cannot be swapped at will. If a swap is required, the referee's consent must be obtained.

3. Free kick: There are two types of free kicks in football matches:

One is a direct free kick, which is mainly aimed at malicious kicking, hitting, tripping, pulling, pushing, touching the ball, insulting the referee, and insulting others.

One is the indirect free kick penalty, which includes dangerous actions, blocking, and set-piece kicks.

4. Penalty Kick

A direct free kick foul in the penalty area will result in a penalty kick. During a penalty kick, players from both teams cannot enter the penalty area. If the defending team enters the penalty area, the goal will be counted, otherwise a penalty kick will be imposed; if the attacking team enters the penalty area, the goal will be re-kicked, otherwise it will be a goal kick for the defending team. During a penalty kick, the goalkeeper can move left and right on the goal line, but cannot move forward.
