In this paper, we study the minimal period problem for even autonomous second order Hamiltonian systems defined on RNwithout any convexity assumption. By using the variational methods, we obtain estimates on the minimal period of the corresponding nonconstant periodic solution of the superquadratic and asymptotically linear Hamiltonian systems.
