[Several biochemical characteristics of rat skeletal musculature during the development under conditions of skeletal muscular loading and hypodynamia].

The weight and biochemistry of the skeletal muscles of rats developing under conditions of the action of the skeletomuscular loads (the I group), under conditions of hypodynamia - at the environmental temperature of 20-22 degrees C (the II group) and at the environmental temperature of 28-30 degrees C (the III group) were studied. Rats of the I group displayed an increase of the mass of the skeletal muscles and also an elevation of protein, glycogen, ATP, creatine phosphate and a decrease of lactic acid content in these muscles. Rats of the III group showed a considerable decrease in the content of enumerated indices both in comparison with indices of control animals and of rats of the I group. This decrease was less marked in rats of the II group.
