May support plasma volume expansion to augment VO2max at altitude; hypothesis-generating and requires larger trials before practice change.
Does plasma volume expansion improve maximal O2 uptake in males during prolonged high-altitude exposure?
Plasma volume expansion improves maximal oxygen uptake during acclimatization to high altitude, suggesting plasma volume decrease contributes to VO2max limitation.
Robach et al. (2000) studied this question.
