ICE HOCKEY
Ice hockey is one of the most action-paced of sports, demanding skillful skating, expert stick-handling, and masterly puck control. The game developed in the frozen expanses of North America, and a hundred years ago became the national winter sport of Canada. It also became very popular in the northern states of the United States, and later spread to Europe, Japan, and even to Australia. The game probably arose from boys playing on the ice. The kids probably fashioned pucks from frozen "horse apples" and adapted tree branches as hockey sticks, and played on cleared stretches of frozen lakes and rivers, and backyard rinks. Soon it was inevitable that teams began to play against each other and leagues were formed. The earliest mention of the team ice hockey game is a newspaper description of the game played at the Victoria Skating Rink in Montreal in 1875 Originally the leagues and national competitions in Canada were amateur.
In 1917 the first professional league was formed, the National Hockey League (or NHL), with four clubs — Montreal Canadians, Montreal Wanderers, Ottawa Senators, and Toronto Arenas. Later clubs were formed in American cities, and the NHL spread to the United States. In 1972 a rival professional organisation was formed, the World Hockey Association (or WHA).
In 1893 lx>rd Stanley, the Governor-General of Canada, presented a silver trophy, the Stanley Cup to the winners and play-offs for the Stanley Cup began, which then became the symbol of professional hockey supremacy. Canadian-style ice hockey spread rapidly in Europe between the two World Wars. In the northern countries it had to compete against bandy Hockey is a team game played on an ice surface, known as a rink. Six players — a goalkeeper, two defence-men, and three forwards constitute a side.
The game is divided into three periods, each lasting twenty minutes of actual playing time with -10-minute intervals. There are five face- off spots whereby the puck is dropped by the referee between the sticks of two players. After a goal is scored, the puck is brought back to center ice for another face-off. The playing area (rink) is 188 to 200 feet long, and about 85 feet wide.
The playing area is subdivided into three zones — defensive, neutral and attacking — by two blue lines (called off-side lines) teams defensive zone is that zone where the goal cage, which it is defending, is located. The zone at- the opposite end of the rink is known as the teams attacking zone. The area between is known as the neutral zone and is divided at the centre by a red line. This line plays an important role in the game's body checking regulations. Players are subject to a variety of penalties leading to their dismissal from the ice for two minutes or more, thus giving the other team a one-man advantage for the duration of the penalty or until a goal is scored.
