The big guy, Dwayne Chambers is a 100m sprinter. His size is almost a requirement of his sport though. I know there are sprinters who are slighter in build(Bolt) but I wouldn't compare a sprinter to a LD runner - the LD runner doesn't need a lot of muscle. In fact if the LD runner did have a lot of muscle he'd burn out so quickly he'd wish catabolism just to keep up with the leaders!LD runners aren't skinny because they run long distances. They're skinny because its non-sensical to be carrying around 185lb-200lb of mass if you want to run for distance. Just as Dwayne is carrying a shit-ton of muscle - he needs a lot of power and bulk to drive him forward. It's perfect that CP lasts about as long as a 100m race really. That's the energy system they're tapping in that sub 10 seconds and it's also the energy system lifters use for maximal lifts.
Right. Another thing is that slow twitch muscle has hardly any potential for hypertrophy.
