title: [Effects of adaptation to exposure to short-term stress on indices of resistance of energy metabolism and contractile function of the myocardium to acute hypoxic hypoxia and reoxygenation].
abstract: Effect of preliminary adaptation to immobilization stress with progressive duration from 15 min. to 1 h (every second day, 8 sessions) on the resistance of indices of myocardial energy metabolism and contractile function to acute hypoxic hypoxia and subsequent reoxygenation was studied. It was shown, that adaptation to short-term stress exposure by some way provided the retention of activities of important enzymes like creatine-phosphokinase and phosphorylase under the harmful action of acute hypoxia and subsequent reoxygenation. At the same time, the ATP restoration and the CP super-restoration were observed during reoxygenation. This effect, in its turn, was accompanied by a more pronounced super-restoration of the heart contractile function than in control.
