Football, which has been played since 1908, is one of the most popular sports in the world. It is played by two teams of 11-18 players who try to advance the ball into their opponent’s ‘end zone’.
The game is timed. During the first half, the offense has a limited amount of time to move the football forward. If they fail to do so within four downs, they lose possession. A successful 10-yard advance earns a team four more downs.
There is a large amount of preparation and practice involved in playing the sport. Teams are required to prepare for several days before a game.
Football can be quite a physically demanding sport. Some players, particularly those in the NFL, are known to spend hours in the gym, preparing for each game.
One of the most popular forms of the game is American Football, which is a league in which 45- to 50-player teams compete on a weekly basis. These teams are divided into different divisions based on where they are from.
Of course, there are many rules and regulations that govern the game. In some cases, the rules can be a little more complex than others. For example, in the NFL, the air capacity of the ball is set between 12.5 and 13.5 psi.
The modern day game of football was influenced by the industrialization of Victorian Britain. Industrialization created a large working class population that was often off work on Saturday afternoons. They looked for new forms of leisure.
