Cardiovascular endurance refers to the ability of the heart, lungs, and blood vessels to supply oxygen to the muscles during prolonged physical activity. It is a key component of overall fitness and is essential for activities like running, swimming, and cycling. Improving cardiovascular endurance can enhance performance in sports and daily activities. Regular exercise, such as aerobic activities like jogging or dancing, can help increase cardiovascular endurance. This type of training strengthens the heart, allowing it to pump blood more efficiently. As a result, individuals can engage in physical activities for longer periods without becoming fatigued.
