Water polo

Water polo is a team water sport. The game consists of 4 quarters (or periods) in which the two teams attempt to score goals by throwing the ball into their opposition's goal. A team consists of 6 field players and one goalkeeper in the water at any one time. In addition to this, teams may have substitute players (up to six under most governing bodies), including up to one substitute goalkeeper. Water polo is a very violent and aggressive sport, meaning that minor fouls occur frequently and exclusion fouls (in which a player is suspended from the game for 20 seconds) are also common.
Some specialist equipment is needed for water polo such as a water polo ball, a ball which floats on the water made from nylon; water polo caps and water polo goals, which are either floating goals or goals which attach to the side of the swimming pool.
In its simplest form, the game consists of swimming (with and without the ball, sometimes with water polo specific strokes), treading water (using a specific technique called theeggbeater kick or simply eggbeater), throwing and catching the ball and shooting. Unlike many other team sports, such as association football, players do not tend to be a "defender" or an "attacker", but rather play as either of these positions depending on where the ball is.
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, notably mainland Europe and the United States of America.

History[edit]

William Wilson, Scottish aquatics pioneer and originator of the first rules of water polo.
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.[1][2] 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 Serbia, Russia, Croatia, Italy, Montenegro, Greece and Hungary), 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 antecedents of the modern game of Water Polo was a game of water ‘hand-ball’ played at Bournemouth on 13 July 1876.[3] 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 6.00pm 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 theArlington 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.[4][5] Early play allowed brute strength, wrestling and holding opposing players underwater to recover the ball; 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[edit]

Note: Rules below reflect the latest FINA Water Polo Rules.[6]
Seven players from each team (six field players and a goalkeeper) are allowed in the playing area of the pool during game play with up to four substitutes.[7] Visiting team field players wear numbered and usually White caps, and home team field players wear usually Blue caps (though any other contrasting colors are now allowed); both goalies wear red caps, numbered "1". Players may be substituted in and out after goals, during timeouts, at the beginning of each quarter, after ordinary fouls and after injuries.[8] During game play, players enter and exit in the corner of the pool, or in front of their goal; when play is stopped, they may enter or exit anywhere.[9]
The game is divided into four periods; the length depends on the level of play:

The game clock is stopped when the ball is not 'in play' (between a foul being committed and the free throw being taken, and between a goal being scored and the restart). As a result, the average quarter lasts around 12 minutes 'real time'. A team may not have possession of the ball for longer than 30 seconds[12] without shooting for the goal unless an opponent commits an ejection foul. After 30 seconds, possession passes to the other team. However, if a team shoots the ball within the allotted time, and regains control of the ball, the shot clock is reset to 30 seconds.[9] Each team may call 1 one-minute timeout in each period of regulation play, and one timeout if the game goes into overtime.[6] During game play, only the team in possession of the ball may call a timeout.[6]

Dimensions of the water polo pool[13] are not fixed and can vary between 20×10 and 30×20 meters. Minimum water depth must be least 1.8 meters (6 feet), but this in reality is sometimes not the case due to practicalities. The goals are 3 meters wide and 90 centimeters high. Water polo balls are generally yellow and of varying size and weight for juniors, women and men. The middle of the pool is designated by a white line. Before 2005, 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 (if marked at all). The "five meters" line is where penalties are shot and it is designated by a yellow line. The "two meter" line is designated with a red line and no player of the attacking team can receive a ball inside this zone.
One player on each team is designated the goalkeeper, assigned to block 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.
Players can move the ball by throwing it to a teammate or swimming with the ball in front of them. Players are not permitted to push the ball underwater in order to keep it from an opponent, or push or hold an opposing player unless that player is holding the ball. Water polo is an intensely aggressive sport, so 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. If a foul is called outside the 5 meter line, the player is either able to shoot, pass or continue swimming with the ball. Water polo players need remarkable stamina because of the considerable amount of holding and pushing that occurs during the game, some allowed, some unseen or ignored by the referees (usually underwater). There are two types of fouls: one (like the scenario above) only results in the "fouler" giving up the ball and backing off; the other results in an ejection or kick out. Ejections are usually given if someone is being a little too aggressive; i.e. drowning or smacking someone. A player can only have 3 ejections before being majored and can not play for the rest of the game. If a player gets a brutality he or she is also not able to finish the game. An example of a brutality would be excessively cruising or intentionally punching someone. Water polo is a physically demanding activity; action is continuous, and players commonly swim 3 kilometers or more during four periods of play.[8]
Water polo is a game requiring excellent hand-eye 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 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 or continue swimming instead of 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 judged to be brutal, the player is ejected for the remainder of the game, with substitution by another teammate after four minutes have elapsed. 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.

Officials[edit]

The game of water polo requires numerous officials. The four main categories are: referee, secretary, timekeeper and goal judge. These can again be qualified into two broader categories: game officials and table officials.

Game officials[edit]

The game officials in water polo are the referee (or referees) and the goal judges. Referees are responsible for making the game run smoothly, and for signalling fouls, goals and other important events. Goal judges are broadly responsible for overseeing their team's goal line and events which occur there. (These are most obviously goals, but also events such as the start of the period.) There are only ever two goal judges or zero (i.e. never a goal judge at one end only).

Referee[edit]

The referees have ultimate power over decisions relating to the game, even (if necessary) overruling decisions from goal judges, secretaries or timekeepers. They have the responsibility of signalling fouls (minor, major, brutality and misconduct), goals, penalties, timeouts, start of play, end of play (to an extent), restart of play, neutral balls, corner balls and goal throws. He or she must attempt to keep all of the rules of water polo to the governing body they are using.
There are always either one or two referees in a game of water polo. At a higher level, two referees are virtually always used, but at lower levels and/or if there are limited available referees, a referee may officiate the game without another.
Originally, referees used flags to indicate possession, but these were replaced in 1997 with hand gestures.[14]
When goal judges are not present or available, the referee(s) my take their place in that they have the decision as to whether the ball has crossed the line etc.
When there are two referees, the ball may be called out of the water for the referees to confer about an appropriate decision and come to an agreement.
Referees have dress codes at higher (and sometimes lower) levels of water polo, and are expected to abide by this. Often, the dress code is all white, but some associations variate this slightly.

Goal judge[edit]

The goal judge is responsible for several parts of the game. These include: signalling when a goal is scored, signalling corner throws, improper re-entry (after an exclusion), to signal when play can start (at the beginning of quarters) and to signal improper restart at the beginning of quarters.
The goal judge is situated (normally sat) perfectly in line with the goal line - one at either end and usually on opposite sides. They remain seated throughout the game.
In practice goal judges are very rarely used at lower levels, but are compulsory at most international matches. Like referees, they will normally have a dress code which they are expected to abide by.
Previously, goal judges would use a red flag to indicate a corner and a white flag for a goal throw, but these have since been replaced with hand gestures.

Basic skills[edit]

Water polo is a team water activity requiring swimming skills including treading water or wrestling before turning back for the opposing team's possession. The front crawl stroke used in water polo differs from the usual swimming style in which water polo players swim with the head out of water at all times to observe the play. The arm stroke used is also a lot shorter and quicker and is used primarily to protect the ball. Backstroke is used by defending players to look for advancing opponents and by the goalie to track the ball after passing. Water polo backstroke differs from swimming backstroke; the player sits up a bit in the water, using eggbeater leg like motions with short arm strokes to the side instead of long arm strokes. This allows the player to see the play and quickly switch positions. It also allows the player to quickly catch a pass.

As all field players are only allowed to touch the ball with one hand at a time, they must develop the ability to catch and throw the ball with either hand and also the ability to catch a ball from any direction, including across the body using the momentum of the incoming ball. Experienced water polo players can catch and release a pass or shoot with a single motion. The size of the ball can overwhelm a small child's hand, making the sport more suitable for older children. There are also smaller balls that can be used by younger children when playing.
  • Treading water: The most common form of water treading is generally referred to as "egg-beater",[15] named because the circular movement of the legs resembles the motion of an egg-beater. Egg-beater is used for most of the match as the players cannot touch the bottom of the pool. The advantage of egg-beater is that it allows the player to maintain a constant position to the water level, and uses less energy than other forms of treading water such as the scissor kick, which result in the player bobbing up and down. It can be used vertically or horizontally. Horizontal egg-beater is used to resist forward motion of an attacking player. Vertical egg-beater is used to maintain a position higher than the opponent. By kicking faster for a brief period, the player can get high out of the water (as high as their suit—below their waistline) for a block, pass, or shot.
  • Reflexes and Awareness: At higher levels of the sport the pace of play rapidly increases, so that anticipation and mental preparation is important. "Field sense" is a major advantage in scoring, even if a player lacks the speed of an opponent.[16]

Positions[edit]

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 consist of the center (or hole set), the point (who also usually plays center back or hole defender), the two wings and the two flats. Players who are skilled in all of these positions on offensive or defensive 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[edit]

The offensive positions include: one center (a.k.a. two-meter offense, 2-meters, hole set, set, hole man, bucket, pit player or pit-man), two wings (located on or near the 2-meter), two drivers (also called "flats," located on or near the 5-meter), and one "point" (usually just behind the 5 meter), 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.
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 (violation), is the motion 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[edit]

Defensive positions are often the same positionally, but just switched from offense to defense. For example, the centre 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.

Goalie[edit]

Goalkeeper blocking a shot
The goalkeeper is generally one of the more challenging positions not only in the sport of water polo, but in any sport. A goalie 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 goalie 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:[17]
  • 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. (Pool depth permitting - most competitions state the pool has to be at least 2 meters deep)[18]
In general, a foul that would cause an ejection of a field player might only bring on a five meter shot on the goalie. The goalkeeper also has one limitation that other players do not have: he or she cannot cross the half-distance line.[17] Also, if a goalie pushes the ball under water, it is not a turnover like with field players. It is a penalty shot, also called a 5-meter shot, or simply, a "5-meter".
