Korfball is a ball sport, with similarities to netball and basketball. It is played by two teams of eight players withfour female players and four male players in each team. The objective is to throw a ball into a netless basket that ismounted on a 3.5 m high pole. Invented by a Dutchman, the sport is played in about 70 countries all over the world,including Taiwan.       In 1902, Nico Broekhuysen, a school teacher from Amsterdam, was sent to Nääs, a town in Sweden, to followan educational course about teaching gymnastics to children. This is where he was introduced to the Swedish game"ringboll." In ringboll one could score points by throwing the ball through a ring that was attached to a 3 m pole.Men and women played together, and the field was divided into two zones, and players could not leave their zone.When Broekhuysen returned to Amsterdam he decided to teach his students a similar game. He replaced the ringwith a basket (for which the Dutch word is korf or mand), so it was easier to see whether or not a player had scored.Broekhuysen also simplified the rules so that children could understand and play the game. Thus korfball was born.The main idea was the same as ringboll, but the new sport now stood on its own.       A korfball match typically consists of two halves or four periods, with the length varying depending on thecompetition. When the match consists of halves, the duration is typically 25 minutes, with periods typically between7 and 10 minutes, with a one-minute break between the first and second periods and between the third and fourthperiods. At half time the break is five or ten minutes. Four players of each team are in one zone and the other fourare in the other zone. Within each zone, a player may only defend a member of the opposite team of the same gender.        At the beginning of the match, one team chooses a particular half of the court. That half will be that team'sdefending zone, with "their" basket in it. Players score by throwing the ball through the opposing team's basket.After two goals, the teams change zones: defenders become attackers and attackers become defenders. In betweenthose zone-changes, attackers cannot set foot on their defending zone or vice versa. At half time the teams swaphalves of the court.       The rules prevent physical strength dominating the game. Blocking, tackling, and holding are not allowed, noris kicking the ball. Once a player has the ball, that player cannot dribble or walk with it; however, the player canmove one foot as long as the foot on which the player landed when catching the ball stays in the same spot. Therefore,tactical and efficient teamwork is required, because players need each other in order to keep the ball moving. Aplayer may not attempt to score when defended, which occurs when the defender is in between the opponent andthe basket, is facing his/her opponent, or is within arm's length and attempting to block the ball. This rule encouragesfast movement while also limiting the impact of players' height compared to their opponents.
