A genomewide admixture mapping panel for hispanic/latino populations
Xianyun, Mao; Bigham, Abigail W; Mei, Rui; Gutiérrez, Gerardo; Weiss, Ken M; Brutsaert, Tom D; León-Velarde, Fabiola; Moore, Lorna G; Vargas, Enrique; McKeigue, Paul M; Shriver, Mark D; Parra, Esteban J (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 ... -
Absence of work efficiency differences during cycle ergometry exercise in Bolivian Aymara
Brutsaert, Tom D; Haas, Jere D; Spielvogel, Hilde (High Altitude Medicine & Biology, 2004)ABSTRACT. This study tested the hypothesis that Andean natives are adapted to high altitude (HA) via high work ef ficiency during exercise in hypoxia. A total of 186 young males and females were tested in Bo livia, ... -
Andean and Tibetan patterns of adaptation to high altitude
Bigham, Abigail W; Wilson, Megan J; Julian, Colleen Glyde; Kiyamu, Melisa; Vargas, Enrique; León-Velarde, Fabiola; Rivera-Chira, María; Rodríguez, Carmelo; Browne, Vaughn A.; Parra, Esteban; Brutsaert, Tom D; Moore, Lorna G; Shriver, Mark D (American Journal of Human Biology, 2013-01-24)Objectives: High-altitude hypoxia, or decreased oxygen levels caused by low barometric pressure, challenges the ability of humans to live and reproduce. Despite these challenges, human populations have lived on the Andean ... -
Effect of developmental and ancestral high-altitude exposure on chest morphology and pulmonary function in andean and european/north american natives
Brutsaert, Tom D; Soria, Rudy; Cáceres, Esperanza; Spielvogel, Hilde; Haas, Jere D (American Journal of Human Biology, 1999)Abstract. Chest depth, chest width, forced vital capacity (FVC), and forced expiratory volume (FEV1) were measured in 170 adult males differing by ancestral (genetic) and developmental exposure to high altitude (HA). A ... -
Effect of developmental and ancestral high-altitude exposure on VO2peak of andean and european/north american natives
Brutsaert, Tom D; Spielvogel, Hilde; Soria, Rudy; Cáceres, Esperanza; Buzenet, Giliane; Haas, Jere D (American Journal of Physical Anthropology, 1999)ABSTRACT. Peak oxygen consumption (V02peak) was measured in 150 adult males (18-35 years old) in Bolivia, using a complete migrant study design to partition developmental from ancestral (genetic) effects of high altitude ... -
Effect of menstrual cycle phase on exercise performance of high-altitude native women at 3600 m
Brutsaert, Tom D; Spielvogel, Hilde; Cáceres, Esperanza; Araoz, Mauricio; Chatterton, Robert T; Vitzthum, Virginia J (The Journal of Experimental Biology, 2002)Summary. At sea level normally menstruating women show increased ventilation (VE) and hemodynamic changes due to increased progesterone (P) and estrogen (E2) levels during the mid-luteal (L) compared to the mid-follicular (F) ... -
Higher arterial oxygen saturation during submaximal exercise in bolivian aymara compared to european sojourners and europeans born and raised at high altitude
Brutsaert, Tom D; Araoz, Mauricio; Soria, Rudy; Spielvogel, Hilde; Haas, Jere D (American Journal of Physical Anthropology, 2000)Abstract. Arterial oxygen saturation (SaO(2)) was measured at 3,600-3,850 m by pulse oximetry at rest and during submaximal exercise in three study groups: 1) highland Aymara natives of the Bolivian altiplano (n = 25); ... -
Permormance of altitude acclimatized and non-acclimatized professional football (soccer) players at 3,600 M
Brutsaert, Tom D; Spielvogel, Hilde; Soria, Rudy; Araoz, Mauricio; Cáceres, Esperanza; Buzenet, Giliane; Villena, Mercedes; Paz-Zamora, Mario; Vargas, Enrique (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 ... -
Rendimiento de futbolistas profesionales aclimatados y no aclimatados a la altura, a 3600 metros
Brutsaert, Tom D; Spielvogel, Hilde; Soria, Rudy; Araoz, Mauricio; Cáceres, Esperanza; Buzenet, Giliane; Villena, Mercedes; Paz-Zamora, Mariano; Vargas, Enrique (PubliCE, 2003-01-05)Resumen. Los partidos del Fútbol Europeo son frecuentemente jugados a nivel internacional en regiones montañosas de Sudamérica. En este estudio, fueron medidas las respuestas del ejercicio durante una ergometría en ciclo ...
