Shanghai, PR China - As the 14th FINA world swimming championships finished on Sunday night (31 July) in Shanghai, young Chinese swimmer Sun Yang not only won the gold medal in the men's 1500m freestyle, the 19-year-old set a new world record of 14 min 34.14 sec.
In doing so, he broke the ten-year-old record of Australia's Grant Hackett, and set only the second world record at the event.
Earlier, on Thursday, Ryan Lochte had defeated Michael Phelps for the second time in the week in the 200-m individual medley, also setting a world record.
These two were a milestone in swimming -- the first since body hugging go-faster polyurethane suits were banned from competition two years ago by FINA - the international swimming federation.
During the two year the specially developed PU suits were worn, world records fell at an alarming rate, and FINA eventually took the decision to ban the suits as providing an unfair advantage.
