	Probably.  I've talked to a few astronauts about movement in zero g
and all of them are usually shocked at how little force is required to
move.  They learn very quickly (b/c of big bruses) to only push off
lightly.  If the cabin they learn in wasn't padded some would have probably
knocked themselves out!
