Seems like the long distance guys hardly move their upper body, whereas sprinters look like their whole skeleton is about to jump out of their bodies from head to toe.
I has mostly to do with the form of exercise itself (and the many variables within that), their nutrition, and other factors, some of which they can control, some of which they can't.
