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, ...

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 ...

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 ...

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 ...

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) ...

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 ...

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 ...
