Biriball

Biriball (Biribol in portuguese) is a water sport similar to volleyball.

The modality was created in Birigui, country side county in Sao Paulo, Brazil, in the late sixties by professor Dario Miguel de Oliveira. It is played in a 4m x 8m x 1,30m swimming pool with a 2,62m height net (2,42 for women), with a specially crafted ball similar to that of water polo but with a smaller diameter. The ball weights approximately 100 grams more than the volleyball one and employs a "super grip" surface technology. The official game is played with four players on each side, but there's also the doubles modality, with two players on each side. Biriball is a highly recommended sport for working all muscle groups with practically no injury risks due to its no contact, low impact on joints nature. Biriball is also suited for all ages and genders, and is recommended for people with minor chronic injuries that feel discomfort or pain while playing other sports.

Matches are decided in best-of-three or best-of-five sets of 21 points, when the matches go up to the last set this set is disputed up to the 20th point instead, and a team needs at least two points of advantage in any circumstance to win a set. So if a 21-points set is drawn at 20x20, the match is extended to 22 points, and so on. The ball can be touched with any part of the player's body, with open or closed hands. The pool's in side borders are neutral, meaning the ball is normally in play after touching them, points are scored when the ball hits the water in the opponent's side or the opponent team commits a fault. As in volleyball, each team can contact the ball no more than three times before the ball crosses the net, while consecutive contacts must be made by different players - except for contacts while blocking, which aren't counted. Players also can't touch the net or they commit a fault and a point is awarded to the opponent team. Unique to the sport is how there's no penetration under and over the net - it's even allowed to block a set being executed in the opponent's side -, the possibility of blocking serves and how there's no lifting (carrying) faults during spikes.

With its fast moving, highly accurate ball and 'closed quarters' action, Biriball is also an extremely competitive sport. There's currently a Brazilian National League [http://www.biribol.com] with teams from São Paulo, Minas Gerais, Mato Grosso do Sul, Goias and Parana. There are many stages held in different cities of the country, and the Brazilian champion is known in the end of the year, after computing all points of the season. The sport has been reckoned officially in the state of São Paulo, and grows rapidly in the country.
