The R Value At Vo2 Max During Maximal Graded Exercise Treadmill Tests Of Coronary Artery Diseased And Nondiseased Subjects, Sherry S. Williams
This study examined the R value at VO2 max during maximal graded treadmill exercise tests to determine if it was a reliable indicator of VO2 max and could therefore be used as a test termination criterion. The subjects in this study were 160 coronary artery diseased (CAD) patients and 170 nondiseased individuals. Data were collected from existing stress test records. The R value was also analyzed to determine if proportions of diseased and nondiseased subjects were the same. The time it took 100 CAD patients to reach VO2 max and exhaustion once R rose above 1.00 was also examined ...
