World record progression 50 metres freestyle

From Wikipedia, the free encyclopedia
Jump to navigation Jump to search

The first world record in the men's 50 metres freestyle in long course (50 metres) swimming was recognized by the International Swimming Federation (FINA) in 1976. In the short course (25 metres) swimming events the world's governing body recognizes world records since March 3, 1991.

The drop in world record times in the 2008/2009 coincided with the introduction of polyurethane suits from Speedo (LZR, 50% polyurethane) in 2008 and by Arena (X-Glide), Adidas (Hydrofoil) and Italian swimming suit manufacturer Jaked (all 100% polyurethane) in 2009. FINA's ban on non-textile suit came into effect on January 2010.[1] FINA also released a list of approved suits.
