Activity 6: Studying the Effect of Stroke Volume on Pump Activity (pp. 66–67)

5. As the stroke volume is increased, it takes longer to fill the pump and the pump rate slows. To maintain adequate blood flow to tissues, the stroke volume must be greater in an athlete if his heart rate is lower. If we keep the rate constant, increasing the stroke volume, causes cardiac output to increase.
