Test de esfuerzo ergométrico en sujetos normales no entrenados, nativos de altura (3.600 m.)
(Instituto Boliviano de Biología de Altura, 1983)
Resumen.
Se presentan los resultados de pruebas de esfuerzo sobre bicicleta ergométrica en 29 sujetos normales de sexo masculino, con edad media de 33 años (21 a 47 años), nativos y residentes de altura (3.600 m. La Paz, ...
Chemoreflex ventilatory response to CO₂ in man at low and high altitudes
(Respiration Physiology, 1972)
Abstract.
On man, a peripheral chemoreflex ventilatory response curve was obtained by measuring ventilatory reactions to the transient inhalation of a CO₂-rich mixture. Experiments have been performed. 1) on lowlanders ...
Enzimas eritrocitarios y cambios metabólicos en el hombre habitante en las grandes alturas
(Instituto Boliviano de Biología de Altura, 1983)
Resumen.
Se presentan valores relativos al metabolismo glicolítico y oxido-reductor del eritrocito en el hombre nativo de la altura y se comparan con valores de los mismos parámetros, generalmente hallados en condiciones ...
Los efectos de hipoxia e hiperoxia de corta duración sobre la circulación pulmonar de nativos de grandes alturas (HL) y del nivel del mar (LL) residentes a 3.600 Mts.
(Instituto Boliviano de Biología de Altura, 1979)
Resumen.
Hemos realizado inhalaciones cortas de O2 y N2 con el fin de analizar el mecanismo responsable para la hipertensión arterial pulmonar que se observa en grandes alturas en los residentes normales y los recién ...
Influencia de una hiperoxia moderada sobre el consumo de oxígeno durante el ejercicio muscular en nativos de la altura
(Instituto Boliviano de Biología de Altura, 1973)
SUMMARY. The authros performed this study to find out why during intense exercise, equal to or approximatly equal to maximal exercise the oxygen consumption is lower at high altitude than that at sea level Hurtado 1064; ...
Methaemoglobin and erythrocyte reducing systems in high-altitude natives
(Annals of Human Biology, 1979)
Summary.
The stress of chronic hypobaric hipoxia present at high altitudes induces a series of adaptive changes in the intermediate metabolism in erythrocytes of high-altitude natives. Aymaras of the high Andean Plateau ...
Effects of exercise on plasma erythropoietin in natives living permanently at high altitude
(Springer Verlag, 1992)
Abstract.
The effects of inspiratory hypoxia on the erythropoietin (EPO) system decisively depend on the duration of the exposure to the hypoxic environment. Whereas a stay of some hours in a hypobaric chamber leads to ...
Ventilatory, circulatory, and metabolic mechanisms during muscular exercise at high altitude (La Paz, 3500 m)
(Springer-Verlag, 1982)
Abstract.
The scientific study of the natives of the Andes in South America is no longer an isolated or exotic undertaking (9). The Andean peoples are undergoing cultural, social, and economic development unequaled in ...
Respiratory and cardiocirculatory responses of acclimatization of high altitude natives (La Paz, 3500 m) to tropical lowland (Santa Cruz, 420 m)
(Springer-Verlag, 1982)
Abstract.
Socioeconomic development of the countries of the Andean region necessitates massive migration of population groups through colonization programs, which mobilize high altitude natives as well as low- landers. ...
Protective effect of female sex hormones against pulmonary hypertension in Bolivian high altitude natives
(High Altitude Medicine & Biology, 2003-02-19)
There is abundant evidence that female sex hormones have protective effects in the systemic circulation in both animals and humans,
but little is known regarding their role in the regulation of the pulmonary circulation. ...
