Cardiovascular efficiency is the health-related factor that is targeted when focusing on improving how well the heart and lungs work together to supply oxygen to the body during exercise. This includes improving the efficiency of the cardiovascular system in delivering oxygen-rich blood to the muscles and organs, as well as in removing waste products such as carbon dioxide. This can lead to improved endurance, stamina, and overall cardiovascular health.
