  We consider the axial-vector form factors of the baryon octet in flavor-SU(3)
chiral perturbation theory. The baryon octet and decuplet and the
pseudoscalar-meson octet are included as explicit degrees of freedom. We
explore the use of on-shell meson and baryon masses in the one-loop
contributions to the axial-vector form factors and focus on a consistent
treatment in terms of chiral power counting. The convergence properties of such
an approach are scrutinized. We discuss the potential for comparison to
upcoming QCD lattice data.
