Cardiorespiratory fitness is a medical term used to describe the capacity of an athlete's body to transfer the necessary oxygen to the muscles and the capacity of the muscles to absorb this oxygen. There are various ways to assess the cardiorespiratory fitness of an athlete, such as the VO2max testing, the Bruce protocol treadmill test, and the beep or bleep test. The more appropriate way to assess the cardiorespiratory fitness is to use a combination of tests since this will give a complete image of the body's fitness level.
