Hockey
Game played with hooked sticks and a small, solid ball, the object being to hit the ball into the goal. It is played between two teams, each of not more than 11 players. Hockey has been an Olympic sport since 1908 for men and since 1980 for women.
Rules
The ground is 91.5 m/100 yd long and 54.9 m/60 yd wide. Goals, 2.13 m/7 ft high and 3.65 m/4 yd wide, are placed within a striking circle of a 14.64 m/16 yd radius, from which all shots at goal must be made. The white ball weighs about 155 grams/5.5 oz, circumference about 228 mm/9 in. Most sticks are about 91 cm/3 ft long and they must not exceed 50 mm/2 in diameter. The game is started by a ‘push-back’ (or ‘bully-off’). The ball may be stopped with the hand, but not held, picked up, thrown or kicked, except by the goalkeeper in his or her own striking circle. If the ball is sent into touch, it is returned to play by a ‘push-in’. The game is divided into two 35-minute periods; it is controlled by two umpires, one for each half of the field.
