Training protocol. The study consisted of the following phases: The subjects were assigned to two training groups. Group A trained under hypoxic condition (HC; 15% O2) comprised of 2 hours/day, 3 days/week for 3 weeks while Group B trained under the same training protocol under normoxic condition (NC; 21% O2). After each training period, five weeks of self-training under usual field conditions was intervened as washout period. After the self-training, the training condition was switched from HC to NC in Group A, from NC to HC in Group B. The work intensity during training was set to be at lactate threshold (LT) under each NC and HC. The subjects were tested at sea level before and after each training period, and measured O2 uptake (O2), blood samples, and muscle deoxygenation were measured during bicycle exercise test.
