The purpose of this study was to investigate how to postural control in reactive recovery response to lateral perturbations. Twenty-one healthy young adluts participated in this experiment. Each participant was tested for twenty-four trials in which four different perturbation magnitudes and two perturbation directions (left and right) were randamly arranged. In the trials, the participants stood in a standard neutral position. In the group with large angular momentum of the whole body in the frontal plane, the peak horizontal ground reaction force towards the fall side and the peak ankle supinator torque of the fall side limb were significantly larger than those in the small angular momentum group (p
