  We perform a detailed study of mesonic properties in a class of holographic
models of QCD, which is described by the Yang-Mills plus Chern-Simons action.
By decomposing the 5 dimensional gauge field into resonances and integrating
out the massive ones, we reproduce the Chiral Perturbative Theory Lagrangian up
to ${\cal O}(p^6)$ and obtain all the relevant low energy constants (LECs). The
numerical predictions of the LECs show minor model dependence, and agree
reasonably with the determinations from other approaches. Interestingly,
various model-independent relations appear among them. Some of these relations
are found to be the large-distance limits of universal relations between form
factors of the anomalous and even-parity sectors of QCD.
