Expired gas was measured in ten trained women who performed 120-min treadmill walking and running at several exercise intensities. Substrate oxidation was computed by substituting determined oxygen uptake and carbon-dioxide output into stoichiometric equations. A constant level of energy expenditure was needed during prolonged exercise at the same intensity, but the enhancement of lipid metabolism with exercise duration led to an increase in fat-derived energy provision and a decrease in the dependency ratio of carbohydrate-derived energy to required energy. Lipid metabolism during low-intensity exercise wasconstantly-enhanced with duration whereas that during moderate- and high-intensity exercise was slowly increased beyond 60 min after initiating exercise and the proportion of fat-derived energy to required energy decreased with increasing exercise intensity. These findings suggest that women inendurance training should continue low-intensity exercise for as long time as possible and that they should select the moderate-intensity to sustain exercise beyond 60 min in order to increase the total volume of energy expenditure.
