When running, the faster you go the more arm movement. 
The faster you go, the smaller the angle forearm, upper arm is. 
While running this angle is quite fixed, as you want to spill little 
energy.
(All this to a certain extend and if you're the guy who runs the 400m 
on golden shoes, you can do it any way you want, you'll win anyway)
