What is normal cardiac output during exercise?

In brief: 25-30 L/min.
There are many variables.
Cardiac output is stroke vol. X heart rate. At rest stroke vol. Is about 70 ml and rate is about 70 beats/min. During exercise cardiac output can be increased by about 5-6 times. The ability to increase cardiac output with exercise decreases with age due to decreased maximal blood volume capacity in the left ventricle (stroke vol.) and decreased maximal heart rate.

In brief: >30 liters/minute
Normal resting cardiac output is between 5 and 6 liters per minute but in very well trained athletes, cardiac output can increase substantially reaching numbers as high as 30 liters per minute.
