Within the framework of two-flavor covariant baryon chiral perturbation theory we have expressed the Chernyak-Zhitnitsky, Ioffe and Dosch currents in terms of chiral fields to provide leading one-loop extrapolation formulae for the leading and next-to-leading twist normalization constants f(N), lambda(1) and lambda(2). Finite-volume effects due to pion loops have been taken into account. The occurring low-energy constants are fitted to data obtained from recent lattice QCD simulations in order to extract the values at the physical point.
