The term "cardiovascular endurance" encompasses the ability of the heart, lungs, and circulatory system to supply oxygen to muscles during sustained physical activity. A higher level of cardiovascular endurance allows individuals to perform exercises for longer durations without fatigue. Engaging in activities like running, cycling, or swimming increases heart rate and strengthens the cardiovascular system over time. Improving this endurance enhances overall fitness, increases stamina, and can contribute to better performance in various physical tasks. It’s a critical component of overall health and well-being, demonstrating the need for regular cardiovascular exercise.
