Web13 de mai. de 2010 · Researchers have been mystified as to how Tibetans have thrived at altitudes over 4400 meters (14,435 feet). Some high-altitude people, such as Andean highlanders, have an adaptation that adds more oxygen-rich hemoglobin to their blood. But many highland Tibetans, researchers have found, have less hemoglobin in their blood. Web12 de dez. de 2013 · The statistical method used in this study was repeated measurement ANOVA. Red Blood Cell (RBC) changes between onset of climbing to 1830 m and 24, 48 and 2 h after sojourn at 1830 m height (after returning from 4000 m altitude) was significant. Mean Cell Hemoglobin (MCH) showed no significant change in any of the altitudes.
