Efectos del acullico de coca en la prueba de tolerancia a la glucosa
(Medicina, 1997)Resumen. Fueron determinados los efectos de la coca, durante el curso de la tolerancia a la glucosa; en 14 sujetos que mascaron coca durante 3 horas y media y en 14 sujetos que no mascaron coca. Ambos grupos son de población ... -
Efectos del acullicu de coca en el metabolismo de la glucosa
(Instituto Boliviano de Biología de Altura, 1997)Aunque el origen de las hojas de coca es tropical y la producción subtropical, su consumo se ha arraigado sobre todo en los pueblos andinos (Carter y Mamani, 1986). Esto explicaría porque los habitantes de regiones altas, ... -
Efectos del consumo tradicional de hojas de coca sobre la respiración
(Instituto Boliviano de Biología de Altura, 1997)La historia documentada sobre las hojas de coca se inicia en 1504 con una carta en la que Américo Vespucio describe sus primeros contactos con los utilizadores de hojas de coa, que había tenido ocasión de conocer en 1499 ... -
Efectos del tabaquismo en una población de altura (La Paz- Bolivia 3600 m.)

Efectos hemodinámicos del ortostatismo en la altura
(Instituto Boliviano de Biología de Altura, 1971)Summary. The authors investigated the hemodynamic repercussions of the orthostatism at high-altitude, in a group of normal subjects, native of the Bolivian Altiplano (High Plateau) (3.700 m.) during rest: in dorsal decupitus ... -
Effect of altitude and socioeconomic status on VO2max and anaerobic power in prepubertal Bolivian girls
(J Appl Physiol, 1996)Abstract The aim of this work was to evaluate the effects of high altitude and low socioeconomic status (SES) on aerobic and anaerobic power in 11-yr-old Bolivian girls. At both high (3,600 m) and low (420 m) altitudes, ... -
Effect of chronic hypoxia and socioeconomic status on the maximal oxygen uptake of 10- to 12-year-old Bolivian boys
(J. Sports Med., 1994)Abstract. The aim of this study was to analyze the effect of altitude and socioeconomic status on the maximal oxygen uptake (VO₂max) of prepubertal Bolivian boys. The subjects were 143 prepubertal boys (10 to 11.5 years ... -
Effect of chronic hypoxia and socioeconomic status on VO2 max and anaerobic power of bolivian boys
(American Physiological Society, 1993)Abstract. The aim of this work was to analyze the effects of altitude and socioeconomic and nutritional status on maximal oxygen uptake (Vo₂max) and anaerobic power (P) in 11-yr-old Bolivian boys. At both high (HA) (3,600 ... -
Effect of developmental and ancestral high-altitude exposure on chest morphology and pulmonary function in andean and european/north american natives
(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
(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 early, short-term supplementation on weight and linear growth of 4-7-mo-old infants in developing countries : a four-country randomized trial 1-4
(Am J Clin Nutr, 1996)Abstract. The effect of supplementation on growth was tested by means of four similar controlled randomized trials in the Congo (n = 120), Senegal (n = 110), Bolivia (n = 127), and New Caledonia (n = 90). Four-month-old ... -
Effect of high altitude on protein metabolism in Bolivian children
(High Altitude Medicine & Biology, 2002-08-01)Abstract. In Bolivia, malnutrition in children is a major health problem that may be caused by inadequate protein, energy, and micronutrient intake; exposure to bacterial and parasitic infections; and ... -
Effect of menstrual cycle phase on exercise performance of high-altitude native women at 3600 m
(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) ... -
