... of mammals is measured as the rate of oxygen consumption during the maximum sustainable rate of exercise [1]. Unlike the basal metabolic rate (BMR), which consumes oxygen at rates far below the ... delivery capacity of the cardiovascular system [1,2], the MMR is largely determined by the maximal rate that the cardiovascular system can deliver oxyge...
