Permormance of altitude acclimatized and non-acclimatized professional football (soccer) players at 3,600 M
(Journal of Exercise Physiology, 2000-04-02)
European football (soccer)
matches frequently are played at the international level in mountainous regions of South America. In this study, the exercise
response during cycle ergometry and the rate of football match ...
Augmented uterine artery blood flow and oxygen delivery protect andeans from altitude-associated reductions in fetal growth
(Am J Physiol Regul Integr Comp Physiol, 2009-02-20)
Abstract.
The effect of high altitude on reducing birth weight is markedly less in
populations of high- (e.g., Andeans) relative to low-altitude origin
(e.g., Europeans). Uterine artery (UA) blood flow is greater ...
Patrones reproductivos en la altura : hipoxia o regulación cultural
(Rev. Arg. Antrop. Biol., 2001)
Where the O2 goes to : preservation of human fetal oxygen delivery and consumption at high altitude
(The Journal of Physiology, 2009)
Fetal growth is decreased at high altitude (> 2700 m). We hypothesized that variation in fetal O2
delivery might account for both the altitude effect and the relative preservation of fetal growth in
multigenerational ...
Intrauterine growth restriction, preeclampsia, and intrauterine mortality at high altitude in Bolivia
(PEDIATRIC RESEARCH, 2003-02-18)
Abstract.
Infant mortality and stillbirth rates in Bolivia are high and birth weights are low compared with other South American countries. Most Bolivians live at altitudes of 2500 m or higher. We sought to determine the ...
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 ...
Greater uterine artery blood flow during pregnancy in multigenerational (Andean) than shorter-term (European) high-altitude residents
(Am J Physiol Regul Integr Comp Physiol, 2007)
Multigenerational (Andean) compared with shorter-term (European) high-altitude
residents exhibit less hypoxia-associated reductions in birth
weight. Because differences in arterial O2 content are not responsible,
we ...
A genomewide admixture mapping panel for hispanic/latino populations
(The American Journal of Human Genetics, 2007-06)
Admixture mapping (AM) is a promising method for the identification of genetic risk factors for complex traits and
diseases showing prevalence differences among populations. Efficient application of this method requires the ...
Does chronic mountain sickness (CMS) have perinatal origins?
(Respiratory Physiology & Neurobiology, 2007-06-29)
Abstract.
Chronic mountain sickness (CMS) occurs in 10% of male high-altitude residents. It is characterized by hypoventilation and hypoxemia but its underlying cause remains unknown. We hypothesized that CMS' origins ...
Evidence that parent-of-origin affects birth-weight reductions at high altitude
(American Journal of Human Biology, 2008-02-19)
Abstract.
Hypoxia exerts a profound depressant effect on fetal growth, lowering birth weight, and raising mortality risk. Multigenerational high-altitude populations are relatively protected from this birth-weight decline, ...
