The temperature dependence of the saturation time of YBa2 Cu3 07 _ x single crystals in the field of a concentrated load has been studied. The activation energy for the motion of twinning boundaries has been determined (Q~ 0.59 + 0.05 eV). This motion is limited by a reorientation of CuO chains due to a migration of oxygen.
