Let S be a compact orientable surface and f be an element of the group Homeo_0(S) of homeomorphisms of S isotopic to the identity. Denote by f a lift of f to the universal cover S of S. In this article, the following result is proved: If there exists a fundamental domain D of the covering S → S such that lim n→+∞ 1 d_n log(d_n) = 0, where d_n is the diameter of f~n(D), then the homeomorphism f is a distortion element of the group Homeo_0(S).
