Association football, otherwise called as simply football, is a competitive team sport typically played between two groups of eleven players. It’s played by about 250 million people in more than 200 different countries and dependencies, which makes it the fourth most popular sport in the world. The game is often referred to as football but is really a combination of kicking a ball with a foot or using two or more legs. This game was played between people using different techniques and has evolved into a well-developed sport with lots of professional and amateur competition around the globe. The game is very popular among men and women from all ages and from all walks of life.
The basic fundamental rules of football are that the ball must touch the ground or a wall before it can be taken. Another important rule is that the ball cannot be played overhead or on top of the heads, either at any angle along the line of the shoulders or right down the middle of the knees. For scoring points the ball must be kicked through the uprights or the goalposts or through the goal frame. A successful conversion is achieved when the ball touches one of the uprights or the post before it lands in the net. If the ball deflects or moves after contact with an uprights or the goalpost, extra time will be awarded.
Another part of the game requires that the last defender should clear the ball from the goalscoring area. Failure to do so results in a foul being charged to that last defender who is then forced to leave his goal and may leave his side. This foul is referred to as a sending off. The sending off stage is normally followed by the sending off and the game being taken off.
Each participant in the game of football is required to wear a uniform which contains stripes or a color. The color of the uniform determines the role that participant plays on the team. The stripes on the uniform help to keep track of the positions of each participant on the field and also help for identification purposes. The length of the stripes is dependent upon the rules governing the game of football.
The game of football can be played in two different types of environments; wet and dry. Wet football involves fifteen players and is played with ten yards per side. A whistle blows and play commences immediately. The game can then either continue with fifteen players in possession of the ball in the center of the foul line, or the referee can change the formation and play using eleven players in the middle of the field with the ball in the center of the foul line. Either way, the play will continue an until the end of the half or the entire match.
The game of football can also be played in indoor arenas. The rules of this game are almost identical to the rules of outdoor football and can be played with only eleven players on each team. The football equipment used for indoor games is usually similar to that used on the field. As with the outdoor game, there are different types of rules applicable for the indoor game of football.
