Let A be a unital real standard Jordan operator algebra acting on a Hilbert space H of dimension at least 2. We show that every bijection \phi on A satisfying phi(a^2 o b) = \phi(a)^2 o \phi(b) is of the form \phi = e \psi where psi is an automorphism on A and e=1 or -1. As a consequence if A is the real algebra of all self-adjoint operators on a Hilbert space H, then there exists a unitary or conjugate unitary operator u on H such that ph(a) = euau* for all a in A.
