Delayed acclimatization of the ventilatory threshold in healthy trekkers.

Journal article

OBJECTIVE: To test the hypothesis that acclimatization to high altitude results in an improvement of the ventilatory threshold (VT). METHODS: Eight lowlanders underwent cardiopulmonary exercise testing with a cycle ergometer to determine VT and peak oxygen uptake (Vo2peak) in Coventry, United Kingdom (altitude: 80 m), on arrival in leh, india (altitude: 3500 m), and after 12 days of acclimatization that included a 5-day high altitude trek up to 4770 m. RESULTS: Vo2peak fell on arrival at 350...
