High Quality Content by WIKIPEDIA articles! Rachel Komisarz (born December 5, 1976 in Warren, Michigan) is an American swimmer. She swam for the United States team at the 2004 Summer Olympics, where she won a gold medal in the women's 4x200 m freestyle relay and a silver medal in the women's 4x100 m medley relay. The aquatic sport of swimming is based on the human act of swimming, that is, locomotion in water by self propulsion, usually with the goal to complete a given distance in the smallest amount of time. There are also swimming competitions based on endurance or precedence rather than speed, such as crossing the English Channel or some other stretch of open water. As a sport, swimming is usually distinguished from other aquatic sports (such as diving, synchronized swimming and water polo) that involve the act of swimming but where the goal is neither speed nor endurance.
