We compute finite-volume corrections to nucleon matrix elements of the axial-vector current. We show that knowledge of this finite-volume dependence -as well as that of the nucleon mass - obtained using lattice QCD may allow a clean determination of the chiral-limit values of the nucleon and {delta}-resonance axial-vector couplings.
