Three groups of criteria can be used to describe ultimate tolerance of the "side-to-side" impact loads by test-subject as a pre-shock or pre-traumatic margin of relatively safe exposure. These groups include subjective signs, regulatory (bradycardia, extrasystole, brief respiratory disturbances) and spinal biomechanics deviations. Physiological experiments with 12 essentially healthy young male volunteers showed that ultimate tolerance of 0.13- to 0.16-second exposure to lateral impact loads varied within the range from 15 to 30 units as a result of body motion restraint with shoulder and hip belts and was 1.8-fold lower with the waste belt only.
