<p>A physiological stress testing apparatus and method which provides customized exercise routines that challenge an individual to achieve the maximal desirable heart rates and exercise stress loads. The method and apparatus applies a gradually increasing workload for a patient on the exercise apparatus regardless of the speed or efficiency at which the patient operates the apparatus. An electromagnetic resistance unit is controlled by a programmable logic controller and a pulse width modulation controller to adjust the resistance applied by the apparatus in order to maximize the workload for the patient. When a patient reaches a maximal workload, this allows the apparatus to automatically calculate a VO<SUB>2</SUB> maximum.</p> |
