  The AdS/QCD models are believed to interpolate between low and high energy
sectors of QCD. This belief 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. For testing the feasibility of high
energy constraints it is interesting to calculate holographically some
observable constants at low and high momenta independently and compare. We
consider an AdS/QCD model describing the Regge-like linear spectrum of spin-1
mesons in a general form and show that under definite 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. The found approximate 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.
