Abstract

Biochemical characteristics of the tissues of rats developing under conditions of increased muscular exertion and hypodynamia (at temperatures of 20–22°C and 28–30°C) were studied. Exertion of the animals led to an increase in the mass of the skeletal muscles, accompanied by an increase in their content of protein, glycogen, ATP, and creatine phosphate and by a decrease in their lactic acid content. In rats developing under conditions of hypodynamia and supplementary heating, the opposite changes were found. Hypodynamia without heating caused no change in the energy and plastic resources of the body.
