There was controversy after the Beijing Olympic Games in 2008 when many Olympic swimmers broke records an unprecedented number of times using revolutionary swimsuits that covered their entire legs. To highlight the issue, in 2008, 70 world records were broken in one year, and 66 Olympic records were broken in one Olympic Games (there were races in Beijing where the first five finishers were swimming faster than the old world record).
As of 1 January 2010, men are only allowed to wear suits from the waist to the knees. They are also permitted to wear one piece of swimwear; they cannot wear briefs underneath jammers. This rule was enacted after the controversy in the Beijing Olympics and Rome World Championships.
