Cardiac output, which is essential for understanding how efficiently the heart is pumping blood, is indeed calculated as a product of stroke volume and heart rate. Stroke volume is the amount of blood ejected by the heart in one contraction, while heart rate is the number of times the heart beats per minute. Therefore, when you multiply these two variables, you determine the total volume of blood being circulated throughout the body each minute, which is the definition of cardiac output.

This relationship is fundamental in both clinical and exercise physiology; it helps assess cardiovascular health, fitness levels, and the body's ability to deliver oxygen to tissues during increased physical activity. Understanding this concept is crucial for anyone working in health and fitness, helping them tailor cardiovascular training programs and recognize signs of potential cardiovascular issues in clients.
