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) over tilde a lift of f to the universal cover (S) over tilde of S. In this article, the following result is proved: If there exists a fundamental domain D of the covering (S) over tilde -> S such that lim(n ->+infinity) 1/n d(n) log(d(n)) = 0, where d(n) is the diameter of (f) over tilde (n)(D), then the homeomorphism f is a distortion element of the group Homeo(0)(S).
