The amount of oxygen taken in can be influenced greatly by the cardiovascular systems ability to deliver oxygenated blood to exercising muscles, the lungs ability to oxygenate the blood and the muscles ability to use the oxygen and extract it for sustained contractions. Disease and inactivity therefore can impair or inhibit these factors consequently reducing a persons ability to function. The second component is the metabolic function in the body, which can be used to control blood sugar levels. During exercise this can be tested by the ability to deal with changes in muscle and blood PH, the more active someone is leads to higher endurance to metabolites and therefore less muscle fatigue. This component can also be linked in with the third component of muscular endurance, with age this factor is often limited by lack of muscular strength due to shorter bouts of exercise being performed. The fourth component of fitness involves coordination and balance, which is highly important for bone structure and being aware of the positions of joints. The fifth component includes
