The decays rho(770) to 4 pi and omega(782) to 5pi are considered in detail inthe approach based on the Weinberg Lagrangian obtained upon the nonlinearrealization of chiral symmetry, added with the term induced by the anomalousLagrangian of Wess and Zumino. The partial widths and excitation curves of thedecays rho^0 to 2 pi^+ 2 pi^-, pi^+ pi^- 2 pi^0, rho^{+-} to 2 pi^{+-} pi^{-+}pi^0, rho^(+-} to pi^(+-} 3 pi^0 are evaluated for e^+e^- annihilation,photoproduction and tau lepton decays. The results of calculations are comparedwith the recent CMD-2 data on the decay rho^0 to 2 pi^+ 2 pi^- observed ine^+e^- annihilation. The omega to 5 pi decay widths and excitation curves ine^+e^- annihilation are obtained. The angular distributions for variouscombinations of the final pions in the decays rho to 4 pi and omega to 5 pi arewritten. The perspectives of the experimental study of the above decays ine^+e^- annihilation, tau lepton decays and photoproduction are discussed.Comment: Revtex, 32 pages including 11 ps figures.
