Munich (dpa) - A German sprint coach on Friday confirmed an old adage that men shouldn't have sex before competition, but added the twist that sexual intercourse before the sprint helps women run faster.
"We can confirm scientific evidence that shows women who had sex shortly before competing have better results,'' German national sprint coach Uwe Hakus said in an interview in the German magazine Fit for Fun.
The coach said women's testosterone levels increase after sex, helping them in competition. Their male counterparts, however, should abstain from intercourse, as Hakus said: ``Their testosterone levels decrease after an organism. Besides it's been proven that men's ability to contract their muscles also decreases.''
