Some aspects of energy metabolism in human blood erythrocytes under hypokinesia and during space flights.

The present investigation presents results of studying energy metabolism in blood erythrocytes in cosmonauts who made the first and the second space flights aboard the orbital station Salyut-4 and in test subjects who experienced 49-d of hypokinesia at -4 degrees. The data obtained throughout the postflight investigations and during the hypokinesia studies appeared to be identical, showing a decrease in glycolytic activity whereas ATP content remained unchanged.
