Artificial turf was first invented in the early 1960s by an RTP research team headed by David Chaney. It was first used for field hockey in the 1970s.
Some artificial turfs have toxins which can cause cancer. Therefore, you must check materials of artificial grass before choosing which one you want.http://www.azluxurylawns.com/fake-grass-lawns
No.Just Ice But street hockey is played on cement
Field hockey playing surfaces vary depending on the level of play. The majority of games are played on grass or on synthetic turf surfaces, depending on who is running the game and the availabaility of the surfaces. Most stronger countries in the sport have turfs enough for everyone to use, while those who are not as strong, see the sport as a minor one only or who cannot normally afford a lot of them use grass or sometimes packed dirt surfaces. Most grades of field hockey above the junior-school level play on artificial surfaces like astroturf; for most national and international games, it is actually required that the surface be one of these turfs.
when was artificial respiration invented
There "appears" to be a spray because in fact there is a spray. All games at the Beijing Olympics hockey tournament were played on the wet base artificial turf specially laid for the tournament. These turfs are covered with a small amount of water before (and somtimes redone at halftime of) each game, in order to help lessen the effect of injury on it and alow the ball to move quicker than if the turf was dry.
It is random. It is usually how many turfs you have there and how strong they are. If you have the most turfs and strongest turfs there you will become the capo
Hockey turfs have a carpet-like surface. By wetting the fields there is less chance of carpet burns or nasty scrapes occurring when skin scrapes the surface (such as when a player falls or scrapes knuckles).
The hockey puck was invented so hockey players had something to shoot into the goal.
The first hockey stick was invented in 1840.
Alan Blake invented underwater hockey in 1954.
the artificial leg was invented in 1909 a whale bone
An infill is used on an artificial hockey turf to help keep the pile upright and decrease wear and tear on the carpet. Water is used as an infill at national and international levels, as it allows more consistancy in ball roll and bounce, free movement of the pile, and more shock absorbance and less abrasiveness than earlier sand-based turfs. Sand-based or hybrid turfs are still used at local and regional levels because water-baesd turfs are more expensive to install and maintain.London 2012 will be the first world event to be played on a different coloured synthetic turf to the traditional green.The water-based surface uses a high-performance polyethylene resin helping to make it the world's fastest pitch.
