A study was conducted to examine the effects of exercise intensity on the duration and magnitude of excess post-exercise oxygen consumption (EPOC) in seven young women who were in the same phase of the menstrual cycle. The subjects exercised on separate days for 30min at an intensity of 40%, 50% or 70% of maximal oxygen uptake (VO2 max) on a cycle ergometer. Oxygen uptake, respiratory exchange ratio, and heart rate were measured while the subjects rested in a sitting position for 4h after exercise. The results were compared with those of an identical control experiment without exercise. EPO...
