Water polo

Water polo is a highly physical and demanding competitive team sport. It is played in an all-deep pool where players cannot touch the bottom.

Each team consists of seven players in the water. This group includes six field players and one goalkeeper. The field players move between offensive and defensive roles throughout the match. The objective is to score goals by throwing a ball into the opposing team's goal. The team with the most goals at the end of four quarters wins. Because it requires constant swimming and strength, it is often called one of the most difficult sports to play.

To move effectively, players must master several physical skills. They use swimming to travel across the pool. To stay upright and stable, they use a special movement called the eggbeater kick.

Players advance the ball by passing to teammates or by dribbling it in front of them. The ball is made of air-tight nylon and is similar in size to a soccer ball. It is designed to float on the water. Players also wear numbered and colored caps to identify their teams. This equipment is essential for both play and officiating during the intense matches.

Modern water polo has many distinct offensive and defensive structures. In offense, the center forward, or "hole-set," stays near the 2-meter line to direct play. Other players include two wings near the goal posts and two drivers near the 5-meter line. A "point" player often stays farthest from the goal.

Teams may use an "arc" or "umbrella" setup where perimeter players surround the goal. Some teams use a "motion c" strategy, also called a "washing machine offence." In this setup, players swim in a square pattern to make man-coverage difficult. This constant motion helps control the game tempo but can be very tiring.

Defensive strategies are equally complex and vary based on the situation. Teams can play "man-to-man" or use specific zones. For example, a "2–4" defense places four defenders along the goal line. Another tactic is the "M drop" defense. In an "M drop," the point defender moves away from his player to help defend the center position. This allows wing defenders to split the area further from the goal. This positioning helps create a clear lane for a counter-attack if the team regains possession.

The goalkeeper holds a unique and vital role in the game. They are responsible for blocking shots and guiding their defense. The goalkeeper has specific privileges within the five-meter area in front of their goal. They are the only players allowed to touch the ball with two hands. They may also punch the ball with a clenched fist to stop a shot. If a goalkeeper pushes the ball underwater, the referee calls a penalty shot rather than a turnover. They often start the offense by passing the ball across the pool to an attacker.

The history of the sport traces back to the mid-19th century. It originated in England and Scotland as a demonstration of strength and swimming skill.

William Wilson, a Scottish aquatics pioneer, is credited with developing the first rules in the 1870s. Early versions were often called "water rugby" or "aquatic football." One recorded match in Bournemouth in 1876 lasted only 15 minutes because the ball burst. The name "water polo" likely comes from the English pronunciation of the Balti word for ball, "pulu." Men's water polo became part of the modern Olympic games in 1900.

Today, water polo is a global sport with many governing bodies. World Aquatics is the international organization that oversees the sport. Regional groups like European Aquatics and the NCAA in the United States manage specific competitions.

The sport is especially popular in Europe, with countries like Spain, Hungary, and Italy having strong traditions. It is also widely played in Australia, Canada, China, and Brazil. Many nations host two main types of competitions. They offer a prestigious double round-robin league for elite clubs and a single-elimination cup for all levels of clubs.
