Abstract
I discuss in this paper the more likely physical mechanisms that could provide the energy input for the supersonic motions observed in giant extragalactic HII regions, together with preliminary results of an ongoing observational program that aims to study, with with high spatial and spectral resolution, the kinematics of the ionized gas of the regions.
