We consider the integral functional of the calculus of variations where f : R nN → R satisfies f (z) = g(|z|) and g is an N-function with subquadratic p-q growth. We prove that minimizers u : Ω ⊂ R n → R N of such a functional are locally Lipschitz continuous, provided g verifies some additional co
