From Wikipedia, the free encyclopedia
The first world record in the 100 metres butterfly in long course (50 metres) swimming was recognised by the International Swimming Federation (FINA) in 1957, for both men and women. In the short-course (25 metres) swimming events, the world's governing body recognizes world records since March 3, 1991.
