The indicators of cardiorespiratory system in rats in conditions of chronic hypokinetic stress on the background of normal and restricted nutrition

Abstract

The article is devoted to the study of indicators of the cardiorespiratory system in rats of different sexes under conditions of chronic hypokinetic stress (HK), on the background of normal nutrition, and also in conditions of longterm restricted nutrition (RN). It was shown that the 21-day exposure to hypokinetic stress, both with a normal type of diet and in conditions of long-term restricted nutrition, has an evident effect on the indicators of the cardiorespiratory system in laboratory animals, which is expressed in the increase of the heart rate on the background of the decreased respiratory rate and depth, and also the decrease in the percentage of oxygen in the rats blood, both males and females.
