Abstract
Studies on the effects of exercise on stroke volume in human subjects were done, using dye dilution method with measurements being made during, not after, exercise. Older studies showing fall in supine resting stroke volume when subject stands erect were confirmed. With increase in exercise loads, stroke volume rises again to the supine resting value and, as loads reach levels producing 2 or more liters of oxygen intake per minute, stroke volume rises significantly. At an exercise load producing maximal oxygen intake stroke volume is about double the resting standing value and is significantly higher than the resting supine.
