Aerobic capacity is closely related to overall fitness level, as it reflects the body's ability to utilize oxygen during sustained physical activity. Higher aerobic capacity enables individuals to perform activities with greater intensity and for more extended periods without fatigue. Improvements in aerobic capacity contribute to better cardiorespiratory fitness, which is essential for overall health. A good aerobic fitness level is typically associated with a lower risk of chronic diseases like heart disease and diabetes. Therefore, enhancing aerobic capacity through exercise is vital for long-term health and fitness maintenance.
