We predict 'heating' of quasiparticles driven by order parameter oscillations in the resistive state of short superconducting microbridges. The finite relaxation time of the magnitude of the order parameter D and the dependence of the spectral functions both on D and the supervelocity Q are the origin of this effect. Our result is opposite to those of Aslamazov and Larkin (Zh. Eks. Teor. Fiz. 70, 1340 (1976)) and Schmid, Schön and Tinkham (Phys. Rev. B 21 5076 (1980)) where 'cooling' of quasiparticles was found.
