Yes, but I think this mostly pertains to people with, "beer guts." Yes, some bodybuilders have stomach distention from organ enlargement, excessive food intake, and doing their ab exercises with their stomachs poked out (yes this one is true). But it doesn't effect it to a large extent in most of the cases I've seen. Use this for an example; take a piece of cloth and loosely wrap it around an un-inflated balloon. Now inflate the balloon and keep the cloth wrapped around it. You'll notice that the empty space between the cloth lessens and balloon make grasping the cloth surrounding the balloon more difficult. This is is just a loose example, and I hope you maybe understand.
