Predictions for g_1(x,Q^2) at low Q^2 are obtained in the framework of the GVMD model. Contributions from both light and heavy vector mesons are evaluated. The DHGHY sum rule is employed to fix the magnitude of the light vector meson contribution to g_1, using the recent measurements in the region of baryonic resonances. The DHGHY moment function is calculated. Predictions are compared to the data.
