It's one of the oldest cliches in the history of sports. A big strapping boxer is all set to enter the ring when his beautiful, buxom girlfriend tries to get a little action from her man before the big bout. That's when his cigar-chomping trainer steps in and proudly proclaims, "No sex before the big fight. It'll ruin your endurance."

The London Games are apparently so rampant with sex that athletes living in the Olympic village are being issued official Olympic condoms. Some of their coaches still believe this adage are even separating married athletes from their husbands and wives during the Games. However, according to Reuters News Service, there doesn't seem to be any scientific evidence to back the superstition.

The majority of the research on the subject has focused on the physical aspects of sex and sports. Researchers say they have not found any evidence that sex can slow a person's performance or aggression...on the field, that is.

One study examined 14 married male athletes who were administered grip tests the morning after a night of sex with their spouses alongside a control grip test without sex. The study, published in the Clinical Journal of Sports Medicine, found no difference in strength or endurance in either test.

Of course, sports fans have known for a long time that the whole "no sex before the big game" concept was total bunk. The scientists and doctors could have saved millions of dollars in unnecessary research and study by just printing two words in their medical journals: Wilt Chamberlain.
