Abstract.
Elevated hemoglobin concentrations have been reported for high-altitude sojourners and Andean high-altitude natives since early in the 20th century. Thus, reports that have appeared since the 1970s describing ...
Pulmonary nitric oxide in mountain dwellers
(NATURE, 2001-11-22)
Nitric oxide is synthesized in the lungs to help regulate blood flow, and its levels have been found to drop in
species native to low altitudes, including
humans, upon acute exposure to reduced

Seasonal and circadian variation in salivary testosterone in rural Bolivian men
(American Journal of Human Biology, 2009-02-19)
Abstract.
Testosterone (T) plays a key role in the increase and maintenance of muscle mass and bone density in
adult men. Life history theory predicts that environmental stress may prompt a reallocation of such investments ...
Percent of oxygen saturation of arterial hemoglobin among Bolivian aymara at 3,900-4000 m
(American Journal of Physical Anthroplogy, 1999)
ABSTRACT.
A range of variation in percent of oxygen saturation of
arterial hemoglobin (SaO2) among healthy individuals at a given high
altitude indicates differences in physiological hypoxemia despite uniform
ambient ...
