Cardiac Output. Cardiac output is the amount of blood your heart pumps out in one minute. It is regulated by the amount of blood your heart pumps out in one contraction, or stroke volume, and the number of times your heart beats in one minute, or your heart rate.Cardiac output increases as a short-term and a long-term effect of regular aerobic exercise.Initially, cardiac output increases due to an increase in your heart rate. Then, as your aerobic fitness improves, cardiac output increases due to an increase in stroke volume and a decrease in heart rate.ardiac output increases as a short-term and a long-term effect of regular aerobic exercise. Initially, cardiac output increases due to an increase in your heart rate.
Best Answer: Cardiac output (Q or or CO ) is the volume of blood being pumped by the heart, in particular by a left or right ventricle in the time interval of one minute- wiki Q = Stroke Volume Ã Heart rate As long as stroke volume is constant, heart rate should increase cardiac output. Think of running up the stairs, you need more oxygen carried to the cells of the body. You increase cardiac output by increasing the heart rate to get more oxygen to the cells. However, Tachycardia is increased heart rate over a longer period of time. While the heart rate is high, the ability for the ventricles to refill is reduced decreasing stroke volume, and then decreasing cardiac output as a result.
