In this work, we present results of a model-dependent analysis of both possible channels in e+e -annihilation into four pions based on 5.8 pb -1 of e+e -data collected with the CMD-2 detector [1] at center-of-mass energies v~ from 1.05 to 1.38 GeV. The data were recorded in 1997 at the VEPP-2M e+e -
