Football markers were first invented in 1876 by Edward L. Dickinson, a teacher at Phillips Exeter Academy. At the time, football was played with a round ball and was not governed by any rules. The markers helped to keep track of where the ball was and who had possession of it.
Today, football markers consist of a small square or rectangular piece of plastic with a white or black border. They are about an inch wide and three inches long. The markers are placed in specific locations on the field, usually near the sidelines but sometimes in other strategic locations as well. Football space markers & accessories help to increase the overall athletic performance.
When a player is yards from the marker, he makes contact with it with his foot. If he touches it before he gets to it, then he has been tackled by an opposing player and is out of bounds. If he touches it after he gets to it, then he has gained possession of the football and can continue playing.
The use of football markers has become so standardized that there are now companies that manufacture them, sell them to schools and supply them to other teams for training purposes. If you want to buy training equipment online, then Splay is the best option for you.
The field markings were first used by the Michigan Wolverines in 1912. The football played with this set of rules was called the "Ticket" game, because an umpire would place wooden tickets on the players' backs as they went out of bounds. These wooden tickets indicated that the players had been out of bounds at various times during the game.
The player who received the most tickets was declared out of bounds and thus did not continue playing for his team. This penalty was later called a safety, which is still in use today to denote when a player has become completely out of play or when a team has taken too many penalties. The game was later changed to five downs, and a forward pass was allowed.
