Introduction: Exercises on a cycle ergometer and on a treadmill are practiced improving physical conditioning. To provide similar adaptations and benefits with these exercises, comparing maximal oxygen consumption (VO2 max) to have intensity equivalence is necessary. Objective: to compare VO2 max between cycle ergometer and treadmill in male adults who practice cross-country and sprint sprints. Materials and Methods: Participants were 10 men, 5 long-distance runners (F), and 5 sprinters (V) aged between 18 and 28 years, VO2 max between 50 and 60 mL/Kg/min, 5-6 days/week of training practice. The VO2 max was estimated with a VO2000 gas analyzer in incremental tests on a cycle ergometer and treadmill. The perceived exertion (RPE) was estimated using the Borg scale. The t-test was compared the F and V, and also the VO2 max between cycle ergometer and treadmill, considering p<0.05. Results: The means for F and V were 21.2±3.1 and 22.5±4.2 years, 58.4±8.9 and 71.0±8.0 kg, 6.0±2.9 and 8.7±2.4% fat, 60.9±9.1 and 52.3±2.1 mL/Kg/min on a cycle ergometer, 68.4±8.3 and 60,1±5.6 V mL/Kg/min on the treadmill and 18.7±1.4 and 17.3±1.0 Km/h for threshold speed on the treadmill, respectively. Conclusion: The differences between F and V were not significant, however, the VO2 max was higher on the treadmill with a difference of 11.7% for that obtained on the cycle ergometer (p<0.05). The RPE on the treadmill was 18±2, while on the cycle ergometer it was 17±3. Considering RPE, intensity control was more accurate in treadmill running.
