Water Polo


Water Polo

Water polo is a team water sport, which can be best described as a combination of swimming, football, basketball, ice hockey, rugby and wrestling. A team consists of six field players and one goalkeeper. The goal of the game resembles that of football (soccer): to score as many goals as possible, each goal being worth one point. A perfect water polo athlete can be best described as having the over-arm accuracy of a baseball pitcher, the vertical leap of a volleyball player, the toughness of a rugby player, the endurance of a cross-country runner and the strategy of a chess player.

History

The modern game originated as a form of rugby football played in rivers and lakes in England and Scotland with a ball constructed of Indian rubber. This "water rugby" came to be called "water polo" based on the English pronunciation of the Balti word for ball, pulu,
Men's
water polo at the Olympics was among the first team sports introduced at the 1900 games (along with cricket, rugby, football (soccer), polo (with horses), rowing and tug of war).[13] Women's water polo became an Olympic sport at the 2000 Sydney Olympic Games after political protests from the Australian women's team.
Every 2 to 4 years since 1973, a men's
Water Polo World Championship is played together with the World Swimming Championship, under the auspices of FINA. Women's water polo was added in 1986. A second tournament series, the FINA Water Polo World Cup, has been held every other year since 1979. In 2002, FINA organized the sport's first international league, the FINA Water Polo World League.

Overview

Note: Rules below reflect the latest FINA Water Polo Rules 2005-2009.
Seven players from each team (six field players and a
goalkeeper) are allowed in the playing area of the pool during game play. Visiting team field players wear numbered white caps, and home team field players wear dark caps; both goalies wear quartered red caps, numbered "1". Both teams may substitute players. During game play, players enter and exit in front of their team bench; when play is stopped, they may enter or exit anywhere.

The game clock is stopped when the ball is not 'in play' e.g. between a foul being committed and the free throw being taken and between a goal being scored and the restart. This causes the average quarter to last around 12 minutes 'real time'. A team may not have possession of the ball for longer than 30 seconds without shooting for the goal or an opponent being ejected. After this time, possession passes to the other team. However, if a team shoots the ball within the allotted 30 seconds, and regains control of the ball, the shot clock is reset to 30 seconds. Each team may call two one minute timeouts in the four periods of regulation play, and one timeout if the game goes into overtime. During game play, only the team in possession of the ball may call a timeout.
Dimensions of the water polo pool are not fixed and can vary between 20 x 10 and 30 x 20 meters. Minimum water depth must be least 1.8 meters (6 feet), but this is often waived for age group or high school games if such a facility is unavailable. The goals are 3 meters wide and 90 centimetres high.
Water polo balls are generally yellow and of varying size and weight for juniors, women and men. The middle of the pool (analogous to the 50 yard line in football) is designated by a white line. In the past, the pool was divided by 7 and 4 meter lines (distance out from the goal line). This has been merged into one 5 meter line since the 2005-2006 season. Along the side of the pool, the center area between the 5 meter lines is marked by a green line. The "five meters" line is where penalties are shot and it is designated by a yellow line. The "two meters" line is designated with a red line and no player of the attacking team can be inside this line without the ball.


One player on each team is designated the goalkeeper, assigned to deflect or catch any shots at goal. The goalkeeper is the only player who can touch the ball with both hands at any time, and, in a shallow pool, the only player allowed to stand on the bottom. This is equal for both teams because at half time, they both switch sides.
Players can move the ball by throwing it to a teammate or swimming while pushing the ball in front of them. Players are not permitted to push the ball underwater when being tackled, or push or hold an opposition player unless that player is holding the ball. Fouls are very common, and result in a free throw during which the player cannot shoot at the goal unless beyond the "5 meter" line. Water polo players need remarkable stamina due to the considerable amount of holding and pushing that occurs during the game, some allowed, some unseen or ignored by the referees (usually underwater). Water polo is one of the most physically demanding of all sports; action is continuous, and players commonly swim 3 kilometers or more during four periods of play.
Water polo is a game requiring excellent eye-hand coordination. The ability to
handle and pass the ball flawlessly separates the good teams from the great teams. A pass thrown to a field position player is preferably a "dry pass" (meaning the ball does not touch the water) and allows for optimal speed when passing from player to player with fluid motion between catching and throwing. A "wet pass" is a deliberate pass into the water, just out of reach of the offensive player nearest the goal (the "hole set") and his defender. The hole-set can then lunge towards the ball and out of the water to make a shot or pass. A goal may be scored by any part of the body except a clenched fist.

Scoring

Scoring in water polo can be quite unique compared to other sports. For example, a "skip" shot is fired intentionally at the water with considerable force so it will bounce back up. The ball usually hits the water within a metre of the net, where the goalie cannot anticipate and block the shot. Another shot, called a "lob" is thrown with a large vertical arc. Often these shots are more difficult to stop than a faster shot, as they are usually thrown across a net at such an angle the goalie must not only shift position from one side of the net to the other quickly, but also at the same time propel out of the water more than for other shots. Pump faking is effective when using any kind of shot. The player gets in the position to shoot but stops halfway through his motion, causing the defending goalkeeper to commit too early to block the subsequent shot.
The referee's whistle for a
foul is heard much more in water polo than in other sports. A defender will often foul the player with the ball as a tactic to disrupt the opponent's ball movement. Play continues uninterrupted in most cases, but the attacker must now pass the ball instead of advancing or taking a shot. (An exception allows players to quickly pick up the ball and shoot if fouled outside of the five meter mark.) However, as in ice hockey, a player caught committing a major foul, is sent out of the playing area with his team a man-down for 20 seconds, but may return sooner if a goal is scored or his team regains possession. If the foul is an unsportsmanlike act, however, the player is ejected for the remainder of the game with substitution by another teammate. A player, coach or spectator can also be ejected for arguing with the referees. During a man up situation resulting from an ejection foul, the attacking team can expect to score by passing around to move the goalkeeper out of position. A player that has been ejected three times must sit out the whole match with substitution.
