obtaining reliable test scores are the obvious reasons for their limitation. However, these tests can make a contribution in terms of identifying persons who are extremely low in terms of cardiorespiratory fitness. When the score is extremely low, it is reasonable to refer the person to a physician for diagnosis. If no pathologic process is involved, then a graduated program of individual instruction should be initiated to ameliorate the deficiency.
Cardiovascular tests might also be employed as a screening process when a medical examination is not given. This does not imply, however, that the test is a substitute for a good medical examination.
