Comparison of 10-12 years old schoolboys living at high (4100m) and at low (450m) altitude in Bolivia
(Int. J. Sports Med., 1992)
Within the frame work of a large project, health and lifestyle was measured in 10-12 years old Indian schoolboys in Bolivia. In 1990 about 50 boys living in La Paz, at an altitude between 3600 and 4100 m, were measured, ...
Hemoglobin Concentration in Children at Different Altitudes in Peru: Proposal for [Hb] Correction for Altitude to Diagnose Anemia and Polycythemia
(Mary Ann Liebert, 2018)
The present study was designed to define the hemoglobin [Hb] increase with altitude in Peruvian children. We suggest the normal range of [Hb] as means +/-2 standard deviations (SD), with a value less than - 2 SD as a ...
The sleep of elite athletes at sea level and high altitude: a comparison of sea-level natives and high-altitude natives (ISA3600)
(Br J Sports Med, 2013-09-03)
ABSTRACT Background Altitude exposure causes acute sleep disruption in non-athletes, but little is known about its effects in elite athletes. The aim of this study was to examine the effects of altitude on two groups ...
Andean high-altitude ancestry does not protect from acute mountain sickness and altitude-induced arterial hypoxemia
(Interciencia Association, 2017)
It is thought that adaptive changes protect high-altitude populations against altitude-induced diseases, but information from well controlled studies is lacking. In a prospective, controlled study, we assessed the prevalence ...

Altitude, heredity and body proportions in northern Chile
Recent studies of the effects of hypoxia on human growth and adult size have focused mainly on the variability of single measurements. In this paper we explore changes with altitude and ethnicity (Spanish‐Aymara ancestry) ...
Long-Term Intermittent Exposure to High Altitude Elevates Asymmetric Dimethylarginine in First Exposed Young Adults
(Mary Ann Liebert, 2017)
Hypoxia-induced dysregulation of pulmonary and cerebral circulation may be related to an impaired nitric oxide (NO) pathway. We investigated the effect of chronic intermittent hypobaric hypoxia (CIH) on metabolites of the ...

In Brazil, there are few studies on mountain ecosystems that aims the biodiversity conservation, even with hymenoptera parasitoids, especially the family Braconidae, a group ecologically important, because they represent ...
Developmental components of resting ventilation among high - and low-altitude andean children and adults
(American Journal of Physical Anthroplogy, 1999)
ABSTRACT This paper evaluates the age-associated changes of resting ventilation of 115 high- and low-altitude Aymara subjects, of whom 61 were from the rural Aymara village of Ventilla situated at an average altitude ...
