%X Objectives: Compare two stair climbing protocols each other with an established cycle-ergometry protocol for smokers. Methods: In an exercise physiology laboratory, 25 smokers¡¯ maximal O2 consumption (VO2max) was determined by cycleergometry at 30W/3min increments. Then, randomly they performed either maximal fixed intensity (FiSC) or bi-level intensity (BiSC) stair-climbing protocols at the same pace to exhaustion, before crossing-over to perform the other 1 to 3 days later. The sequence was repeated 6 weeks later. The FiSC was performed on a 10 flight staircase. The BiSC was performed by repeatedly climbing and descending a single flight. Outcome measures were exertional dyspnea (ED), Leg pain (LP), respiratory rate (RR), heart rate (HR), pulse Oximetry (SpO2), blood pressure, physiologic cost index (PCI), and self-reported preferences. Results: All 25 subjects climbed the single-flight BiSC 10 times but no one could climb more than 8 consecutive flights (FiSC). Eighty to 95% of Heart rate at VO2max was achieved by both, but the BiSC was significantly better tolerated over ten flights, because it presents significant differences with the FiSC for HR (<001), PCI (<.001), ED and LP (p <0.05), which are lower, while RR (<.001) and SpO2 (<.004) .are significantly higher. In addition, it can be realized with only one flight, for the subject himself, because he works under the surveillance of medical staff that controls the speed of climbing, and the subjective and cardiorespiratory responses. Conclusion: The protocol of exercise climbing stairs with two levels and one flight is more practical, for the subject and the specialized Staff that survey the subjective and cardiorespiratory responses, and is better tolerated than that of the FiSC
