"Iíd mention that, even due to activities of daily living, the lower body usually gets some work (walking, climbing stairs) while the upper body frequently does not. Itís possible that some of the difference in growth is related to this. We know that untrained muscles grow more effectively than trained muscles so perhaps the relatively less trained nature of the upper body is responsible for the faster growth. Since this study and the one linked above did have some simple leg movements that didnít cause growth, I see this as a possibility."
So it was addressed, PERIOD.
Yeah I just mentioned that and was agreeing. :/
