Hematological adaptations following descent from high altitude to low altitude.

Data are presented as mean ± SD with the number of subjects (M,W) indicated in parentheses. Subjects were studied at sea level, at 5260 m after 16 days high altitude acclimatization, and upon initial return to 5260 m after descent to 1525 m for 7 (POST7) or 21 (POST21) days. Linear mixed model statistical analyses were performed to examine the effects of time (with POST as the reference), group (POST7 versus POST21) and a time × group interaction. Effects were accepted as significant when p≤0.05. There were no significant effects of group or any significant group × time interactions (all p>0.05).Hematological adaptations following descent from high altitude to low altitude.
