U.S. Swimming Executive Hints at Doping Sixteen-year old Chinese swimmer Ye Shiwen raised some eyebrows after her unbelievable world-record swim in the 400-meter individual medley, but some immediately accused the teenage sensation of doping. Shiwen smashed the world record by over a second and even out-paced Ryan Lochte's final 50 meters in the men's event, causing USA Swimming executive John Leonard to effectively accuse Ye of doping. Leonard claimed that Ye "looks like Superwoman. Any time someone has looked like Superwoman in the history of our sport they have later been found guilty of doping." Leonard pointed to China's spotty history of doping offenses and did not back off of the claim.
