We investigate the dependence of the axial-vector transition form factor and radius of the nucleons on the temperature of the medium, using the AdS/QCD soft-wall model which is based on AdS/CFT duality. The dependencies of the axial-vector transition form factor and radius of nucleons on the square of the momentum transfer and the temperature are plotted. We observe that the value of the axial-vector transition form factor and the radius of nucleons decreases as increases temperature.
