I don't have any data, so this means nothing, but I can see the application for building strength and endurance over muscle mass. Though, if you find a hill and do the same thing, i.e. ride up out of the saddle and pull up on the bars, you're doing pretty much the same thing. So it's a bit of a moot point.
