Apolo Ohno Yawning: Yawns Provide Strategic Advantage (PHOTOS)

Apolo Ohno yawning may have been a strange sight to viewers of the Vancouver Olympics last weekend. Even as he became the most decorated U.S. Winter Olympian of all time, Ohno's pre-race yawn appeared out of place.

Yet according to Fourth Place Medal, Ohno's yawning is all about strategy. "The yawning lets extra oxygen into his lungs in the seconds before bursting across the ice," writes Martin Rogers. And indeed, as Ohno's rigorous training methods show, he seeks every advantage possible. Scroll down for pictures of Ohno's yawns in action.
