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.

And indeed, as Ohno's rigorous training methods show, he seeks every advantage possible. Scroll down for pictures of Ohno's yawns in action.
