Apparently the secret is to wear red.
:condom:
In each event Olympic staff randomly assigned red or blue clothing or body protection to competitors. When otherwise equally matched with their opponent in fitness and skill, athletes wearing red were more likely to win the bout.
Hill and Barton got the idea for their study study out of a mutual interest in the evolution of sexual signals in primates—"red seems to be the color, across species, that signals male dominance and testosterone levels," Barton said.
For example, studies by Setchell, the Cambridge primate researcher, show that dominant male mandrills have increased red coloration in their faces and rumps. Another study by other scientists shows that red plastic rings experimentally placed on the legs of male zebra finches increase the birds' dominance.

The pair say their results indicate that sexual selection may have influenced the evolution of humans' response to color.
