Swimming Women's 100m Breaststroke - Heats Full Replay from the Aquatics Centre at the London 2012 Olympic Games. -- 29 July 2012

Swimming has featured on the programme of all editions of the Games since 1896. The very first Olympic events were freestyle (crawl) or breaststroke. Backstroke was added in 1904.

In the 1940s, breaststrokers discovered that they could go faster by bringing both arms forward over their heads. This practice was immediately forbidden in breaststroke, but gave birth to butterfly, whose first official appearance was at the 1956 Games in Melbourne. This style is now one of the four strokes used in competition.
