Water polo



Water polo is a team water sport. The game consists of four quarters in which the two teams attempt to score goals by throwing the ball into their opponent's goal. The team with the most goals at the end of the game wins the match. A team consists of 6 field players and one goalkeeper in the water at any one time. Except for the goalkeeper, players participate in both offensive and defensive roles. In addition to this, teams may have substitute field players and substitute goalkeepers who are not in the water. Water polo is typically played in an all-deep pool 7 feet deep and players require stamina and endurance to play the game.

Water polo is a contact sport. Minor fouls occur frequently and exclusion fouls (in which a player is suspended from the game for 30 seconds or until a goal is made, whichever comes first.) are common.

Special equipment for water polo includes a water polo ball, which floats on the water; numbered and colored caps; and two goals, which either float in the water or are attached to the side of the pool.

The game consists of swimming (with and without the ball), using a special form of treading water known as the eggbeater kick, throwing, catching, and shooting the ball. All throwing and catching must be done using a single hand except the goalkeeper.

The game is thought to have originated in Scotland in the late 19th century as a sort of "water rugby". William Wilson is thought to have developed the game during a similar period. The game thus developed with the formation of the London Water Polo League and has since expanded, becoming widely popular in various places around the world, including Europe, the United States, Brazil, China, Canada and Australia.

History


The history of water polo as a team sport began as a demonstration of strength and swimming skill in late 19th century England and Scotland, where water sports and racing exhibitions were a feature of county fairs and festivals. Men's water polo was among the first team sports introduced at the modern Olympic games in 1900. Water polo is now popular in many countries around the world, notably Europe (particularly in Hungary, Serbia, Croatia, Montenegro, Russia, Italy, Greece and Spain), the United States, Canada and Australia. The present-day game involves teams of seven players (plus up to six substitutes), with a water polo ball similar in size to a soccer ball but constructed of waterproof nylon.

One of the earliest recorded viewings of water polo was conducted at the 4th Open Air Fete of the London Swimming Club, held at the Crystal Palace, London on the 15th September 1873. Another antecedent of the modern game of Water Polo was a game of water ‘hand-ball’ played at Bournemouth on 13 July 1876. This was a game between 12 members of the Premier Rowing Club, with goals being marked by four flags placed in the water near to the midpoint of Bournemouth Pier. The game started at 6:00 pm in the evening and lasted for 15 minutes (when the ball burst) watched by a large crowd; with plans being made for play on a larger scale the following week.

The rules of water polo were originally developed in the late nineteenth century in Great Britain by William Wilson. Wilson is believed to have been the First Baths Master of the Arlington Baths Club in Glasgow. The first games of 'aquatic football' were played at the Arlington in the late 1800s (the Club was founded in 1870), with a ball constructed of India rubber. This "water rugby" came to be called "water polo" based on the English pronunciation of the Balti word for ball, pulu. Early play allowed brute strength, wrestling and holding opposing players underwater to recover the ball. Players held underwater for lengthy periods usually surrendered possession. The goalie stood outside the playing area and defended the goal by jumping in on any opponent attempting to score by placing the ball on the deck.

Rules
The rules of water polo cover the play, procedure, equipment and officiating of water polo. These rules are similar throughout the world, although slight variations to the rules do occur regionally and depending on the governing body. Governing bodies of water polo include FINA, the international governing organisation for the rules; the NCAA rules, which govern the rules for collegiate matches in the United States; the NFHS rules which govern the rules in high schools in the USA and the IOC rules which govern the rules at Olympic events.

Overview of game play
In a water polo team, 6 players are assigned to attacking and defensive roles (commonly known as "fielders"), while one is assigned to the goalkeeping role. The primary aims of the fielders are to score goals and to prevent the other team scoring against their own team's goalkeeper. The goalkeeper's primary role is to stop shots from the opposing team going into his or her own goal.

Game play broadly includes swimming with and without the ball, passing both to a player's hand and onto the water and shooting. Fouls are very common, and these affect the game play, since the victim of a minor or a major foul will have the advantage of a free throw or a 6 on 5 advantage where one player is excluded for 20 seconds and the other team gets an advantage, while the victim of a penalty foul will have the opportunity of a one-on-one shot against the opposing team's goalkeeper.

Positions
There are seven players in the water from each team at one time. There are six players that play out and one goalkeeper. Unlike most common team sports, there is little positional play; field players will often fill several positions throughout the game as situations demand. These positions usually consist of a center forward, a center back, the two wing players and the two drivers. Players who are skilled in all positions of offense or defense are called utility players. Utility players tend to come off of the bench, though this is not absolute. Certain body types are more suited for particular positions, and left-handed players are especially coveted on the right-hand side of the field, allowing teams to launch 2-sided attacks.

Offense
The offensive positions include: one center forward (also called a "set", "hole-set", "center", "setter", "hole", or "2-meter man", located on or near the 2-meter, roughly in the center of the goal), two wings (located on or near the 2-meter, just outside of the goal goal posts, respectively), two drivers (also called "flats", located on or near the 5-meter, roughly at the goal posts, respectively), and one "point" (usually just behind the 5 meter, roughly in the center of the goal, respectively), positioned farthest from the goal. The wings, drivers and point are often called the perimeter players; while the hole-set directs play. There is a typical numbering system for these positions in U.S. NCAA men's division one polo. Beginning with the offensive wing to the opposing goalies right side is called one. The flat in a counter clockwise from one is called two. Moving along in the same direction the point player is three, the next flat is four, the final wing is five, and the hole set is called six. Additionally, the position in which a player is can give advantages based on a player's handedness, to improve a shooting or passing angle (for example, the right wing is often left handed).

The most basic positional set up is known as a "3–3", so called because there are two lines in front of the opponent's goal. Another set up, used more by professional teams, is known as an "arc", "umbrella", or "mushroom"; perimeter players form the shape of an arc around the goal, with the hole set as the handle or stalk. Yet another option for offensive set is called a 4–2 or double hole; there are two center forward offensive players in front of the goal. Double hole is most often used in "man up" situations, or when the defense has only one skilled "hole D", or to draw in a defender and then pass out to a perimeter player for a shot ("kick out").

The center sets up in front of the opposing team's goalie and scores the most individually (especially during lower level play where flats do not have the required strength to effectively shoot from outside or to penetrate and then pass to teammates like the point guard in basketball). The center's position nearest to the goal allows explosive shots from close-range ("step-out" or "roll-out", "sweep", or backhand shots).

Another, albeit less common offense, is the "motion offense", sometimes nicknamed "washing machine offense", in which two "weak-side" (to the right of the goal for right-handed players) perimeter players set up as a wing and a flat. The remaining four players swim in square pattern in which a player swims from the point to the hole and then out to the strong side wing. The wing moves to the flat and the flat to the point. The weak side wing and flat then control the tempo of play and try to make passes into the player driving towards the center who can then either shoot or pass. This form of offense is used when no dominate hole set is available, or the hole defense is too strong. It is also seen much more often in women's water polo where teams may lack a player of sufficient size or strength to set up in the center. The best advantage to this system is it makes man-coverage much more difficult for the defender and allows the offense to control the game tempo better once the players are "set up". The main drawback is this constant motion can be very tiring as well as somewhat predictable as to where the next pass is going to go.

Defense
Defensive positions are often the same, but just switched from offense to defense. For example, the center forward or hole set, who directs the attack on offense, on defense is known as "hole D" (also known as set guard, hole guard, hole check, pit defense or two-meter defense), and guards the opposing team's center forward (also called the hole). Defense can be played man-to-man or in zones, such as a 2–4 (four defenders along the goal line). It can also be played as a combination of the two in what is known as an "M drop" defense, in which the point defender moves away ("sloughs off") his man into a zone in order to better defend the center position. In this defense, the two wing defenders split the area furthest from the goal, allowing them a clearer lane for the counter-attack if their team recovers the ball.

Goalkeeper
The goalkeeper has the main role in blocking shots against the goal. He or she has to be able to jump out of the water, using little more than one's core and legs, and hold the vertical position without sinking into the water, all while tracking and anticipating a shot. The goal is 2.8 m2 in face area; the goalkeeper should also be a master of fast, effective lateral movement in the water as well as lightning fast lunges out of the water to block a shot. Another key job that the goalkeeper is responsible for is guiding and informing his or her defense of imposing threats and gaps in the defense, and making helpful observations to identify a gap in the defense that the defenders may or can not see. The goalkeeper is also the "quarterback", as he or she usually begins the offensive play. It is not unusual for a goalie to make the assisting pass to a goal on a break away.

The goalkeeper is given several privileges above those of the other players, but only if he or she is within the five meter area in front of his or her goal:
 * The ability to punch the ball with a clenched fist.
 * The ability to touch the ball with two hands.
 * The ability to touch the bottom of the pool.

In general, a foul that would cause an ejection of a field player might only bring on a five-meter shot on the goalkeeper. The goalkeeper also has one limitation that other players do not have: he or she cannot cross the half-distance line. Also, if a goalkeeper pushes the ball under water, the action will not be punished with a turnover like with field players, but with a penalty shot.

Advancing the ball
When the offense takes possession of the ball, the strategy is to advance the ball down the field of play and to score a goal. Players can move the ball by throwing it to a teammate or swimming with the ball in front of them (dribbling). If an attacker uses his/her arm to push away a defending player and free up space for a pass or shot, the referee will rule a turnover and the defense will take possession of the ball. If an attacker advances inside the 2-meter line without the ball or before the ball is inside the 2-meter area, (s)he is ruled offside and the ball is turned over to the defense. This is often overlooked if the attacker is well to the side of the pool or when the ball is at the other side of the pool.

Setting the ball
The key to the offense is to accurately pass (or "set") the ball into the center forward or hole set, positioned directly in front of the goal ("the hole"). Any field player may throw the hole set a "wet pass". A wet pass is one that hits the water just outside the hole set's reach. A dry pass may also be used. This is where the hole set receives the ball directly in his hand and then attempts a shot at the cage. This pass is much more difficult because if the pass is not properly caught, the officials will be likely to call an offensive foul resulting in a change of ball possession. The hole set attempts to take possession of the ball [after a wet pass], to shoot at the goal, or to draw a foul from his defender. A minor foul is called if his defender (called the "hole D") attempts to impede movement before the hole set has possession. The referee indicates the foul with one short whistle blow and points one hand to the spot of the foul and the other hand in the direction of the attack of the team to whom the free throw has been awarded. The hole set then has a "reasonable amount of time" (typically about three seconds) to re-commence play by making a free pass to one of the other players. The defensive team cannot hinder the hole set until the free throw has been taken, but the hole set cannot shoot a goal once the foul has been awarded until the ball has been played by at least one other player. If the hole set attempts a goal without the free throw, the goal is not counted and the defense takes possession of the ball, unless the shot is made outside the 5-meter line. As soon as the hole set has a free pass, the other attacking players attempt to swim (or drive) away from their defenders towards the goal. The players at the flat position will attempt to set a screen (also known as a pick) for the driver. If a driver gets free from a defender, the player calls for the pass from the hole set and attempts a shot at the goal.



Man-Up (5 on 6)
If a defender interferes with a free throw, holds or sinks an attacker who is not in possession or splashes water into the face of an opponent, the defensive player is excluded from the game for twenty seconds, known as a 'kick out' or an ejection. The attacking team typically positions 4 players on the 2 meter line, and 2 players on 5 meter line (4–2), passing the ball around until an open player attempts a shot. Other formations include a 3–3 (two lines of three attackers each) or arc (attackers make an arc in front of the goal and one offensive player sits in the 'hole' or 'pit' in front of the goal). The five defending players try to pressure the attackers, block shots and prevent a goal being scored for the 20 seconds while they are a player down. The other defenders can only block the ball with one hand to help the goalie. The defensive player is allowed to return immediately if the offense scores, or if the defense recovers the ball before the twenty seconds expires.

Defense strategy
On defense, the players work to regain possession of the ball and to prevent a goal in their own net. The defense attempts to knock away or steal the ball from the offense or to commit a foul in order to stop an offensive player from taking a goal shot. The defender attempts to stay between the attacker and the goal, a position known as inside water.

Goalkeeper
Even with good backup from the rest of the defenders, stopping attacks can prove very difficult if the goalkeeper remains in the middle of the goal. The most defensible position is along a semicircular line connecting the goalposts and extending out in the center. Depending on the ball carrier's location, the goalie is positioned along that semicircle roughly a meter out of the goal to reduce the attacker's shooting angle. The goalkeeper stops using his or her hands to tread water once the opponent enters at about the 7 meter mark and starts to lift their upper body using the eggbeater technique to prepare to block the shot. Finally the goalie tries to block the ball down, which is often hard for the longer reaches, but prevents an offensive rebound and second shot. As is the case with other defensive players, a goalkeeper who aggressively fouls an attacker in position to score can be charged with a penalty shot for the other team. The goalkeeper can also be ejected for twenty seconds if a major foul is committed. Also inside the five meter mark, the goalie can swing at the ball with a closed fist without being penalized.

Advantage rule
If an offensive player, such as the center forward, has possession of the ball in front of the goal, the defensive player tries to steal the ball or to keep the center from shooting or passing. If the defender cannot achieve these aims, he may commit a foul intentionally. The hole set then is given a free throw but must pass off the ball to another offensive player, rather than making a direct shot at the goal. Defensive perimeter players may also intentionally cause a minor foul and then move toward the goal, away from their attacker, who must take a free throw. This technique, called sloughing, allows the defense an opportunity to double-team the hole set and possibly steal the inbound pass. The referee may refrain from declaring a foul, if in his judgment this would give the advantage to the offender's team. This is known as the Advantage Rule.

Injuries
Water polo is a contact sport, with little protective gear besides swim suits and caps with ear protectors. Among the most common serious injuries are those affecting the head and shoulders. Those induced to the head are usually caused by elbows or the ball itself. One case would be when the defense guards the offense, the defense are right behind offense trying to steal the ball or trying to stop the ball from scoring or being passed. So as a result of the offense trying to shake off the defense to either score or pass the ball, a lot of elbowing and forceful removal from the defensive grab is needed. Many times the head being the main body part out of the water is injured in such a way. Many times these injuries are intentional and can sometimes anger many players to take revenge. Another common injury would be in the shoulder. Throwing or shooting the ball with a "cold arm" can strain the shoulder if not warmed up properly. Also occasionally, the defensive player will sometimes pull the arm to foul the offensive player. This can also injure the shoulder. With the arm, fingers are also usually harmed, due to not catching the ball right or blocking the ball. Many sprained fingers or on a more serious scale, fractured fingers have resulted from water polo. Some of the most injured players on the field are the goalies. They have to endure the ball thrown at them at a fast speed and are expected to "throw it down" to prevent the ball from going into the goal and scoring. When blocking shots the ball can hit the fingers instead of the whole hand causing fractures and strains. Goalies have also been known to suffer nosebleeds. Other injuries take place underwater as many things can not be seen from above the surface and not much padding is used to protect the players.

While playing one major injury that can occur is a labrum tear in the shoulder. The labrum is the cartilage that extends the glenohumeral joint of the shoulder which helps in stabilizing the shoulder. A labral tear can result from activities such as falling wrong, lifting heavy objects, or any other strong force running through the shoulder. Such forces exist in water polo from the continuous stresses of swimming as well as the forces caused from throwing the ball and/or having the pass or shot blocked. This is evident as labral tears are commonly found in people who participate in throwing sports. Tearing the labrum will result in the weakness of the arm. The continued weakening or injury of the labrum can ultimately cause the joint to become so weak that subluxation or dislocation of the shoulder can occur.

Sunburn is a common minor injury in outdoor matches. The irritation of the sunburn can be restrictive because of the sheer amount of movement involved in the sport. Players will often neglect applying sunscreen as this will impair the player's ability to grip the ball and rapidly deteriorate the ball's physical grip due to the oily nature of sunscreen. Having large amounts of sunscreen on during an official match is banned by FINA and most other state/national governing bodies.

Eye irritation from pool chlorine is also common because players cannot wear goggles. They are regarded as a safety hazard because they may cause cuts, bruises or suction injuries during player-to-player contact or if the player is hit in the face by the ball.

Variations
Inner tube water polo is a style of water polo in which players, excluding the goalkeeper, are required to float in inner tubes. By floating in an inner tube players expend less energy than traditional water polo players, not having to tread water. This allows casual players to enjoy water polo without undertaking the intense conditioning required for conventional water polo.

Surf polo, another variation of water polo, is played on surfboards. First played on the beaches of Waikiki in Hawaii in the 1930s and 1940s, it is credited to Louis Kahanamoku, Duke Kahanamoku's brother.

Canoe polo or kayak polo is one of the eight disciplines of canoeing pursued in the UK, known simply as "polo" by its aficionados. Polo combines paddling and ball handling skills with a contact team game, where tactics and positional play are as important as the speed and fitness of the individual athletes.

Water polo equipment
Little player equipment is needed to play water polo. Items required in water polo include:
 * Ball: A water polo ball is constructed of waterproof material to allow it to float on the water. The cover is textured to give players additional grip. The size of the ball is different for men's, women's and junior games.
 * Caps: A water polo cap is used to protect the players' heads and ears, and to make them identifiable from afar. Home team field players wear numbered white caps; Visiting team field players wear numbered dark-colored or black caps. Both starting goalkeepers wear red caps (sometimes quartered), numbered "1" (substitute goalies' caps are numbered either "13" for FINA international play or "15" for NCAA play) Caps are fitted with ear protectors.


 * Goals: Two goals are needed in order to play water polo. These can either be put on the side of the pool, or in the pool using floaters.
 * Mouthguard: A mouthguard is not mandatory in most tournaments, but is recommended.
 * Swimwear: Male water polo players wear either swim briefs or jammers (thigh-length trunks). Female players must wear a one-piece swimsuit. Suit-grabbing fouls are common, so players often wear tight-fitting suits, and may layer on several suits at a time for additional security. Many swimwear labels also sell specialized water polo suits that feature reinforced stitching and tougher fabric.  Female water polo suits are generally one-piece outfits which do not have open backs, but zip securely up the back so as to not have straps that can be easily grabbed.

Major competitions
Men's water polo at the Olympics was the first team sport introduced at the 1900 games, along with cricket, rugby, football, polo (with horses), rowing and tug of war. Women's water polo became an Olympic sport at the 2000 Sydney Olympic Games after political protests from the Australian women's team.

One of the most historically known matches often referred to as the Blood in the Water match, was a 1956 Summer Olympics semi-final match between Hungary and the Soviet Union. As the athletes left for the games, the Hungarian revolution began, and the Soviet army crushed the uprising. The Hungarians defeated the Soviets 4–0 before the game was called off in the final minute to prevent angry Hungarians in the crowd reacting to Valentin Prokopov punching Ervin Zador.

Every 2 to 4 years since 1973, a men's Water Polo World Championship is organized within the FINA World Aquatics Championships. 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.

There is also a European Water Polo Championship that is held every other year.

Professional water polo is played in many southern and eastern European countries like Serbia, Croatia, Greece, Hungary, Italy, Russia, Spain, etc. with the LEN Euroleague tournament played amongst the best teams.

There is also a World Club Water Polo Challenge.
