Sperimentale: Lung function at sea level and at 2850m
Assessment of lung function and pulmonary resistance/reactance on day four at sea level (after prior descent from 2850m) and after re-ascent (after totally one week at sea level) back to 2850m by bus (in one day)
|
Descent from 2850m to sea level with a stay for 7 days and re-ascent/return back to their usual living altitude at 2850m
