Abstract: The authors gave an overview of the effects of the fluctuation of estrogen and progesterone levels in the menstrual cycle on substance metabolism and related hormones during an endurance exercise.Previous researches indicated that during a medium or low intensity exercise estrogen can increase lipid oxidation and reduce glucose utilization,achieving the effect of carbohydrate saving.On the basis of estrogen functions,progesterone promotes lipid oxidation and enhances the aerobic exercise capacity.During an aerobic exercise done in the corpus luteum pe-riod with a relatively high level of estrogen and progesterone,the lipid oxidation capacity of the body is higher than the same in the ovarian follicle period,while the carbohydrate utilization capacity of the body is lower than the same in the ovarian follicle period.The menstrual cycle has no significant effect on the basic values and sport induced re-action values of insulin,catecholamine hormone,growth hormone and glucocorticoid.Therefore,during sports training the effects of the menstrual cycle on substance metabolism should be considered in order to fully exert physiological potentials of female athletes.
