We have studied the evolution of isolated galaxies over several Gyr using a self-consistent N-body code including stars, gas and star formation. The results of our simulations are calibrated using spectrophotometric evolution models. We thus simultaneously analyse kinematical and photometrical evolution of the various stellar populations born during the successive bursts of star formation. Our calibrated simulations show that the properties of stellar velocity dispersion drops observed in the centre of three barred active galaxies by Emsellem et al. (2001) could depend on the observational wavelength.
