Cameron van der Burgh, the South African gold medalist of the 100-meter breaststroke Olympic event admitted to cheating last week during the meet. He admitted to performing an illegal move that would have gotten him immediately disqualified had the judges seen it.
The breaststroke swimmers are allowed one dolphin kick underwater during their pullouts.The rule is a relatively new one that came in to play when four-time gold medalist Kosuke Kitajima, a japanese breaststroker, added rogue kicks to his underwater pullouts on a routine basis, hence angering rival swimmers such as American Brendan Hansen. So the rules were changed to allow one kick, but you give an inch, and they take a mile. These swimmers are attempted to sneak in as many kicks as possible in an attempt to gain ground on their rivals, without drawing the judges and officials attention of course.
