Corrected entry: During the "Gonna Fly Now"-walk with the kids near the end-fight, the kid running behind Rocky is getting instructions on when to speed up his run. You see him take a quick peek to the left and then speed up. He is obviously being waved at or something.

Correction: He is a child; it is very easy to capture his attention. Maybe he saw something he was running past that needed a closer look or maybe he thought he heard someone call his name. Either way, you can't categorically say that there is no reason for him to turn his head other than to get instructions.
