[Oxygen utilization by muscle tissue of the dolphin Phocaena phocaena].

Studies have been made on the oxygen consumption in different parts of the cardiac muscle, as well as in deep and subcutaneous muscles of the porpoise Phocaena phocaena. It was shown that oxygen consumption in the heart (especially in the left ventricle) is higher than in skeletal muscles. The intensity of tissue respiration of deep body muscles is approximately 4 times higher than that of subcutaneous ones. Experimental and predicted data were compared. It was suggested that the intensity of oxygen consumption in the skeletal muscles of the porpoise is not uniform during the respiratory cycle.
