Field hockey
Field hockey is a team game of the hockey family. The game can be played on grass, water turf, artificial turf or synthetic field as well as an indoor board surface. Each team plays with eleven players, including the goalie. Players use sticks made out of wood, carbon fibre, fibre glass or a combination of carbon fibre and fibre glass in different quantities (with the higher carbon fibre stick being more expensive and less likely to break) to hit a round, hard, plastic ball.
