Water polo is one of the toughest team sports in the world: swimming, throwing, wrestling – all at the same time, for 32 minutes, without touching the edge of the pool. It's handball in the water, with the endurance of a triathlete and the physicality of a wrestling match.

The fascination lies in the combination of tactical depth, technical skill, and extreme physical exertion. Water polo has been an Olympic sport since 1900 (men) and 2000 (women) – one of the oldest Olympic team sports in the world.

What is water polo?

Two teams of seven players each (one goalkeeper, six field players) in the water. Objective: To throw the ball into the opponent's goal. Playing time: 4 x 8 minutes (effective playing time). Pool: 25-30m long, 20m wide, at least 1.80m deep (feet must not touch the bottom).

The special feature

Unlike land-based sports, players constantly swim to stay afloat. Continuous footwork (treading water) is required even during breaks in play. Body contact occurs underwater – invisible to spectators and often to referees. The game is three-dimensional: horizontal and vertical movement within the water.

Water polo requires a wide range of technical skills that go beyond normal swimming.

Eggbeater Kick

The basic movement in water polo. Legs rotate alternately like a mixer – this keeps the player vertically stable. It allows free hands for the ball and defense. It can be sustained for hours (with training). Variations: Quick upward kicks, sideways movement.

Water polo crawl

Head above water: Unlike swimming, the head is usually above water (for visibility). Ball handling: The ball is held in front of the head in the 'bow wave'. Sprint: Fast swimming with and without a ball.

Fit

Dry pass: The ball flies through the air, and the receiver catches it dry. Wet pass: The ball lands in the water in front of the receiver. Various throwing techniques: overhead (standard), sidearm, backhand. Timing and precision are critical.

Goal shot

Overhead shot: The standard goal shot, fired high from the water. Skip shot: The ball bounces on the water – difficult for the goalkeeper. Lob: A looping shot over the goalkeeper. Penalty (5m throw): A direct shot from the 5m line.

Water polo has specialized positions with different requirements.
