### Description

The AdS/QCD models are believed to interpolate between low and high energy sectors of QCD. This claim is usually based on observations that many phenomenologically reasonable predictions follow from bounds imposed at high energies although the hypothetical range of applicability of semiclassical bottom-up holographic models is restricted by the gauge/gravity duality to low energies where QCD is strongly coupled. To test the feasibility of high energy constraints it is interesting to calculate holographically several observable constants at low and high momenta independently and compare. We will discuss an AdS/QCD model which describes the Regge-like linear spectrum of spin-1 mesons in a general form and demonstrate that under certain physical assumptions the low-energy constraints on 2-point correlation functions lead to nearly the same numerical values for the parameters of linear radial spectrum as the high energy ones. This coincidence looks surprising in view of the fact that such a property for observables is natural for conformal theories while real strong interactions are not conformal.
