At the onset of exercise, the cardiovascular system adapts with a series of integrated responses to meet the metabolic demands of the exercising muscles. The importance of rapid increases in cardiac output and local muscle blood flow has been established by showing that small decreases in O2 supply at the onset of exercise cause delays in the increase in O2 utilization. With the development of techniques that can be applied to instantaneous measurement of the cardiovascular response, the… CONTINUE READING
