It's all about the dimples!

Can a track suit with dimples similar to a golf ball help Usain Bolt set a new world record at the 2012 Summer Games in London?

Nike thinks so.

The Company says the dimple pattern, which is similar to the dimple pattern used in golf ball technology, will shave up to .023 seconds off of its athletes 100-meter time. A fraction of a second may not seem like much, but in the world of track and field it could be the difference between a new world record and not.
The mega-brand developed the suit over thousands of hours of wind tunnel tests, and as a result, it’s zoned with aerodynamic dimples that reduce drag on an athlete’s shoulders, arms, and calves (areas where resistance is strongest). How do these textured zones improve speed? They rely on the same science that explains the convex dimpled pattern found on golf balls. Those dimples help balls travel further because they create low pressure turbulence in the boundary layer on the wind-facing side of the ball as it’s flying through the air, which ultimately means less drag behind the ball. The tiny circular shapes on Nike’s suit work according to the same principle.
Regardless of whether or not Usain breaks his own record in a few months, it's still cool to think that the same technology golfers rely on to his it longer and straight may help athletes in different sports.

Isn't that cheating?

Didn't they do something like that with the swimsuits at the last Olympics?
mjaber says:
One problem- When running, the movement of the body is constantly changing the aerodynamics, making it nearly impossible for this to be anything more than a marketing gimmic. The dimples will move, expand, stretch, and return to their original position, most likely limiting or even elimnitaing any benefit.

If I wore that suit i'd quickly end up slicing into the next lane.
