Comparison of Responses to Submaximal Exercise in Middle-aged and Young Women

It has been demonstrated that the functional capacity of cardiorespiratory system af maximal exercise declines with aging (Hossack and Bruce, 1982). Recently deVries et al. (1982) showed the close similarity in physiological responses to sub-maximal exercise in old and young men of equivalent fitness. The present study investigates the effect of age on physical work capacity by comparing oxygen uptake and heart rate at sub-rhaximal exercise between middle-aged women and young women.
