What term describes the amount of blood pumped by the heart in one minute?

Cardiac output refers to the volume of blood the heart pumps per minute and is a critical physiological measure in assessing cardiovascular health and fitness levels. This term is calculated by multiplying stroke volume, which is the amount of blood ejected from the heart with each contraction, by heart rate, the number of beats per minute. Understanding cardiac output is essential for fitness professionals as it reflects how effectively the heart is functioning during rest and physical activity. A higher cardiac output is often indicative of better cardiovascular fitness, as it suggests that the heart can deliver more oxygen-rich blood to muscles during exercise.

Dynamic training, elastic elongation, and exercise do not specifically define the amount of blood pumped by the heart in one minute, making them less relevant in the context of this question. Dynamic training typically involves exercises that promote movement and flexibility, while elastic elongation refers to the ability of muscles to stretch. Exercise is a broad term for physical activity but does not quantify heart function directly like cardiac output does. Therefore, the definition and calculation of cardiac output are essential for accurately evaluating cardiovascular performance.
