Maximal oxygen consumption (VO2max)is the most commonly used test to quantify a subject’s cardiovascular ability. The measurement of VO2max is used as avalue for the relative expression of exercise intensity. The purpose of this study was to evaluate the VO2 and ventilatory threshold (VT) values of cycle ergometer and treadmill training modalities. The subjects' maximal oxygen consumption values were 75 ml/kg/min for treadmill and 71 ml/kg/min for cycle ergometer exercise test. The subject's VT was 62% and 69% of VO2max for the cycle ergometer and run protocols, respectively. As for comparisons of VO2max between the two exercise modalities, the subjects displayed similar values for both modes. The subjects recorded significantly higher values in both VO2max and VT for the treadmill versus the biking protocol.
Abstract

As for comparisons of VO2max between the two exercise modalities, the subjects displayed similar values for both modes. The subjects recorded significantly higher values in both VO2max and VT for the treadmill versus the biking protocol.
