Let $$\mathcal {A}$$ A be a Hölder continuous cocycle over a hyperbolic dynamical system with values in the group of diffeomorphisms of a compact manifold $${\mathcal {M}}$$ M . We consider the periodic data of $$\mathcal {A}$$ A , i.e., the set of its return values along the periodic orbits in the base. We show that if the periodic data of $$\mathcal {A}$$ A is bounded in $$\text{ Diff }^{\,q}({\mathcal {M}})$$ Diff q ( M ) , $$q>1$$ q > 1 , then the set of values of the cocycle is bounded in $$\text{ Diff }^{\,r}({\mathcal {M}})$$ Diff r ( M ) for each $$r<q$$ r < q . Moreover, such a cocycle is isometric with respect to a Hölder continuous family of Riemannian metrics on $${\mathcal {M}}$$ M .
