翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Inner tube water polo ： ウィキペディア英語版 Inner tube water polo Inner tube water polo (ITWP) is a variation of the sport water polo with the important difference that players, excluding the goalkeeper, are required to float in inflatable inner tubes. By floating in an inner tube, players experience less contact and expend less energy than traditional water polo players, not having to tread water. This allows casual players to enjoy water polo without undertaking the intense conditioning required for conventional water polo. This sport is predominantly played at universities by intramural coed teams,〔(Cassavaugh, Dan. Not Your Ordinary Intramurals. Imprint Magazine. )〕 but can also be found in recreational adult leagues. The sport's rules resemble those of water polo, however, with no governing body the rules vary across different leagues. For example, while the winner is determined by the team which scores the most goals, some leagues award one point for a male goal, and two points for a female goal, while others award one for either. == History == The game was invented in 1969 by now retired UC Davis associate athletic director of intramural sports and sport clubs, Gary Colberg.〔(Gary Colberg: Inner tube water polo )〕 Noticing how much fun the water polo team was having, Mr. Colberg thought up the idea of using tubes so that people with no experience in water polo could still enjoy the game. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Inner tube water polo」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
