The purpose of cardiovascular endurance training is to improve the efficiency of the heart and lungs, enhancing overall fitness levels. This type of training involves sustained activities that elevate heart rate, promoting better blood circulation and oxygen transport throughout the body. Improved cardiovascular endurance allows individuals to perform daily activities with less fatigue and reduces the risk of chronic diseases. It is essential for athletes, as it improves performance, but also benefits the general population by enhancing stamina and promoting better overall health.
