It has been a question in the minds of many clinicians and investigators whether the thirty minute rest period commonly used before basal metabolic tests served as sufficient time for the body to come to basal conditions especially in the case of patients who come from a distance. Benedict and Crafts1 demonstrated that after a thirty minute rest the energy metabolism of normal women was only slightly increased following muscular exercise consisting of the usual morning routine as compared with the test made after a night's rest in bed. The question arose whether these observations would be applicable to obese and underweight subjects, and further whether subjects who had more vigorous exercise would require a longer period of rest. The present investigation was therefore undertaken.
A total of forty-one experiments consisting of four tests each were conducted on thirty-five women, thirteen of whom were obese, fifteen normal and
