Aerobic fitness, measured by the ability to consume oxygen, relates to the heart, blood vessels,

and lungs working together to deliver oxygen-rich blood to the muscles during exercise. A high

level of aerobic fitness is associated with lower risks of several diseases, including high blood

pressure and coronary heart disease. In a study of aerobic fitness, a sample of 31 men involved

in a physical fitness course at a university was randomly selected. The measurements included

Oxygen : the oxygen intake rate (ml per kg body weight per minute),

RunPulse: the heart rate while running.

Our goal is to examine whether oxygen consumption is dependent upon the heart rate while

running.
