The ability of the cardiovascular and respiratory systems to efficiently transfer oxygen and nutrients to skeletal muscles is known as cardiorespiratory fitness or aerobic capacity. This capacity reflects how well the heart, lungs, and muscles work together during physical activity. Improved cardiorespiratory fitness enhances endurance, overall health, and performance in various physical activities.
