Water Polo is a competitive team sport where two teams attempt to swim and score a goal by throwing a ball into the opposing teams net. Originally played to showcase an individuals strength and swimming skills, water polo has continued to be a constant team sport in the Olympic games since 1900. Typical teams consist of 6 field players and 1 goal keeper, with the winning team having scored the most goals during the four quarters of the game. During the course of the game, players are required to tread water, and often use an eggbeater technique to stay afloat.
Water polo is played on a 30 meter (98 feet) by 20 meters (65 feet) with two teams of 7 players: one goalie and 6 field players. The objective of the game is to swim for the ball in the beginning and score a goal on your opposing team's net.
A water polo match has four eight-minute periods that combine for total 32-minute playing time. Time can be affected by the 30-second shot clock if the opposing team takes too long to shot, or fouls and penalties can also make the match last longer.
The minimum depth of water in water polo must be 1.8 meters (6 feet) for practicality purposes. Any lower than that and players won't be able to swim comfortably especially since field players cannot touch the ground when playing.
