Maximum oxygen consumption at altitude

摘要: On 11 subjects, members of an Himalayan expedition, observations have been collected on maximum oxygen consumption (\(\dot V_{O_2 } ^{\max \)) and some respiratory circulatory characters at sea level altitude after a 60 days acclimatization period. The most striking changes as compared with the values (= 1.00) are: a) a fall in exercise ventilation to ab. 0.78; b) a energetic efficiency respiration 0.55; c) a vital capacity 0.87; d) a PACO2 0.55; e) an increase blood haemoglobin 1.32; f) a decrease VO2max 0.44 and g) a heart rate 0.80.
