The rapid p-mode oscillations observed in EC 14026 stars offer interesting opportunities to constrain, with the tools of asteroseismology, the main parameters that define their internal structure. We present the structural properties of sdB stars that are emerging from our detailed asteroseismic studies. We find, in particular, that these properties seem to follow (and thus confirm) expectations from standard EHB stellar evolution. We also show that asteroseismology of EC 14026 stars should play a crucial role in solving the long-standing puzzle of the evolution mechanisms that lead to the formation of extreme horizontal branch stars.
