The correct answer is B:

HR = 80% of age-predicted maximum is NOT a reason to stop maximal GXT.

Explanation:

Maximal graded exercise test allows physicians to evaluate patients ability to perform cardiovascular exercise (functional capacity), an also detect if there are any zones of ischemia in the muscle heart due to arteriosclerosis.

To do so, the patient would be asked to walk on a treadmill and speed and slope of the treadmill will be increased gradually during the test. EKG, heart rate, and blood pressure will be recorded and compared afterwards.

The heart rate target to make a proper evaluation is 85% of the maximal predicted heart rate.
