I've heard working out can stun a growing child's growth. Though I don't know how true that is.
I saw a program on discovery channel in which a teenage female weightlifting prodigy elicited fears that that she would get stunted were she to continue in her hobby.
It's probably due to the growth plates getting closed earlier than expected to the lateral/longitudinal stresses that are exerted upon the bones.
