Nice little piece in The NY Times on the importance of relaxation to performance. They site the Michael Phelps example, of course, but I'd point to the Usain Bolt/Asafa Powell example as the more glaring one. As Anthony Lane put it in his opening paragraph to his excellent piece on the Olympics:
The morning of Friday, August 15th, was one of unaccustomed freshness in Beijing, and it brought forth two objects, both wreathed in legend but hitherto hard to spot. The first was a boiling ball of gases some ninety-three million miles away, known as the sun. The second was the sprinter Usain Bolt, whose homeland lies more than eight thousand miles away, in Jamaica, but who was now a hundred and thirty metres from where I sat. I was close to the finish line of the hundred-metre track, and he was at the start, awaiting his first heat of the Games, and going through his pre-race routine: glancing to the heavens and beating a brief tattoo, with his index fingers, on an invisible drum. He shimmied on the spot, revving his muscles, as all athletes like to do--the most febrile being Rafael Nadal, the young minotaur of the tennis circuit, who hops up and down, before every match, like a small boy in need of a pee. Bolt's nerves were less twitchy than that. Indeed, from this first heat up to the final, the following night, he seemed to be participating less in an Olympic sport than in a gargantuan party, which happened to have a sporting theme. My deepest fear was that he would break the world record and then test positive for rum and Coke.
Lane's first article is even better. Read 'em both (although it's a bit after-the-fact now).
