For clearing the bar, it certainly helps to be skinny. People with a bit more heft will have more leg muscle, but they can't lift their own weight in that way as easily. Of course muscle tissue is denser than fat, so if someone trains a lot they can still have more muscle and better jumping ability, they just won't look fat even if they weigh more.

@ChristopherHallett That would certainly help for both strength and endurance, and is pretty much what I was saying. You would build up muscle and weigh more than someone who gets fat, but be stronger.
