Method: 4 crews were chosen as subjects of the study (age 30.5±16.46yr, height 166.7±1.71cm, weight 65.1±1.41kg, VO2max 42.2±8.42 ml．kg-1．min-1). Their VO2max, Maximal duration time, Ventilation (VE) and Ventilatory anaerobic threshold (VAT) were estimated by treadmill (using Bruce Protocol test). Peak Anaerobic Power (peak-AnP), Anaerobic Capacity ( AnC) and Fatigue Index (FI) were estimated by ergometer ( using Quebec 10 sec test). Changes in blood cells were tested by TOA 9000 analyzer. Descriptive Statistics was used to analyze the data. Result: Sea level aerobic performances were significantly improved after 25 days of climbing, but anaerobic capacities showed a tendency to decrease. At the beginning of being at altitudes, the stimulation of low partial pressure of O2 result in the increase of erythropoieth, which leaded to the significantly increase of red blood cells, hemoglobin, hematocrit (HCT) and mean cell volume (MCV) after returned to the sea level. However, the rated perceived exertion (RPE) returned to the normal state when they went back to the sea level. The muscle mass, body fat % and body weight of the subjects significantly decreased. Conclusion: Climbing Mt. Lenin Peak resulted in the increase of the number of blood cells, which improved sea level aerobic performances. However, because of bad appetite and weight loss, the muscle strength of the subjects decreased, which leaded to lower anaerobic performances.
