Bottled Lightening

Biomechanists have studied how fast a man can run 100m, and have made models looking at the 100m record progression.

Usain Bolt:

"combines the mechanical advantages of taller men's bodies with the fast-twitch fibers of smaller men.....Bolt is an outlier. He's enormous......Typically when you get someone that big, they can't start.....We don't really know what the best form is and maybe Bolt is redefining that and showing us we missed something"

From Wired Science: Bolt Is Freaky Fast, But Nowhere Near Human Limits. As read in an article the other day, the next record holder awaits.
