Aerobic endurance refers to the ability of the body to sustain prolonged physical activity by efficiently using oxygen. It is a key component of overall fitness and is essential for activities like running, swimming, and cycling. Improved aerobic endurance allows individuals to perform at higher intensities for longer periods without fatigue. Training for aerobic endurance typically involves activities that elevate the heart rate, such as jogging, cycling, or dancing. Regular aerobic exercise strengthens the heart and lungs, enhances blood circulation, and increases the efficiency of oxygen delivery to muscles. This leads to better performance in both sports and daily activities.
