Effect of developmental and ancestral high altitude exposure on chest morphology and pulmonary function in Andean and European/North American natives

Article Abstract:

People born and raised at high altitudes (HA) develop larger chests and greater lung capacity than those born and raised at low altitudes. This was the conclusion of a study of 170 men in Bolivia. Some were born and raised at one altitude, some migrated from one to the other, and some had ancestors who lived at another altitude. The study showed that both genetic factors and exposure to HA during development resulted in greater lung capacity and larger chests.

Validity of published prediction equations for body composition in high altitude Bolivian Aymara as evaluated by doubly labeled water

Article Abstract:

A study was conducted to seek simple predication equations for Bolivian Aymara in a field setting. Total body water, fat-free mass, and fat percentage were estimated by a technique called doubly labeled water. However, results showed that using these equations would result in substantial underestimation of fat percent.

Oxygen saturation and heart rate in healthy school children and adolescents living at high altitude

Article Abstract:

Percent oxygen saturation of hemoglobin and heart rate have been studied in three groups of children living at high altitude in the Peruvian Andes. The group with the greatest proportion of Quechua ancestry had the highest oxygen saturation and the lowest heart rate.
