Exceptional levels? What are the different tools we can use to measure aerobic power? What are the advantages/disadvantages of each of these tools?  INTERPRETING THE CLINICAL EXERCISE TEST Heart Rate Responses - The normal HR response to incremental exercise is to increase with increasing workloads at a rate of ~10 beats·min-1 per 1 MET. - HRmax decreases with age and is attenuated in patients on β-adrenergic blocking agents. Several equations have been published to predict Hrmax. - All estimates have large interindividual variability with standard deviations of 10 beats or more.

There is normally no change or a slight decrease in diastolic blood pressure (DBP) during 1000 : Ex an exercise test mmHy Specific SBP responses: Hypertensive response; Hypotensive Response; Blunted Response; Postexercise response. Diastolic BP: Should stay the same or decrease slightly due to vasodilation in the vessels of the exercising muscles. Increase of less than 10 mm Hg in DBP from resting values is considered normal as long as the resting values are within the normal range of 50 to 90 mm Hg at rest. Test should be stopped if DBP reaches 115 mm Hg.

An ischemic score is created by drawing a line between the maximal degree of ST depression and the presence and character of angina during exercise. This ischemic score is balanced with either the duration of exercise on the Bruce treadmill protocol or the number of METs achieved. By drawing a line between the ischemic score and the exercise score, either the 5-year survival or the average midpoint of annual mortality can be computed. Depending on U angina the judgment of the physician, 5-year survival predictions >95% may indicate that medical/behavioral therapy should be given a chance as first-line therapy. In contrast, 5-year immst deviation survival predictions
