Abstract

Previous experiments with intermittent exercise showed that even during very heavy exercise little or no increase in lactate was found in the blood if the work periods did not exceed 5–15 seconds (1,2,3). From these results it was suggested that the myoglobin in the muscle acted as an oxygen store, the store being employed at the onset of exercise and refilled immediately after work. To analyse further the physiology and biochemistry of intermittent exercise some of the earlier experiments have been repeated with the addition that muscle biopsies have been included in the protocol.
