Aerobic capacity refers to the maximum amount of oxygen the body can utilize during intense exercise. It is a key indicator of cardiovascular fitness and endurance. Higher aerobic capacity allows individuals to perform physical activities for longer periods without fatigue, making it essential for athletes and active individuals. Measuring aerobic capacity often involves tests like the VO2 max test, which assesses how efficiently the body uses oxygen. Factors influencing aerobic capacity include age, genetics, training, and overall health. Improving aerobic capacity can enhance performance in sports and daily activities, contributing to better overall health and well-being.
