I was watching Pavliuchenko/Khodykin's short program at euros and noticed that during their side by side spin, someone (their coach probably) was telling them when to change positions: https://youtu.be/cuK-7zV8M8o?t=96 It sounds like he's saying "up" but it's probably another word in Russian. Is this allowed? If so, is it a common practice for competitions? I would think the arena, especially at big comps, would be too loud for the coach to be heard.
