She uses the energy from her opponent's attacks to make herself stronger. If she's not getting attacked, where is she getting the extra energy from? Maybe it could 'activate' without getting hit, but it sure as hell shouldn't have any effect beyond just changing her eyes in that case. It's entirely possible that she can keep the energy she gained stored within her, at least for a certain amount of time. That would actually allow her to take a few hits in a fight and then use that energy in another fight a while later.

One old theory was that Yang stores the energy in her hair and so the longer her hair, the more energy she can store. That theory came from Lindsay saying in an interview that part of Yang's power comes from her hair and that her hair glowing is her charging up the energy.
