Rat experiments have demonstrated that the development of the hypokinetic syndrome involves occurrence of a three-stage stress-reaction characterized by a change in the general health state, body mass, and activity of the hypothalamic-pituitary-adrenal system. The hypokinetic stress affects total resistance and ionizing radiation sensitivity of animals. At a certain stage of development the hypokinetic stress contributes to the state of elevated "cross" resistance.
