Inclusion criteria
Inclusion criteria: 1. All participants were healthy, non-smoking adults who had not adapted to high altitude. 2. Age between 18 and 55 years of age, living at an altitude below 1,000 feet (about 305) The age limit was set to reduce the potential hidden collusion of older participants and heart disease risk, because of plans to do daily, exhausting workouts at high altitudes. 3. Participants also need to pass drug screening and physical examination, and have a normal base before enrollment laboratory indicators (hematology, clinical biochemistry, and urinalysis).
Exclusion criteria
Exclusion criteria: 1. The main exclusion criteria include a history of cardiovascular, cerebrovascular, respiratory, renal, hepatic or other major comorbidities; 2.
