THE INFLUENCE OF BODY CHARACTERISTICS ON HUMAN TEMPERATURE RESPONSES TO HIGH ALTITUDE COLD
Abstract
In order to determine the possible role of body characteristics in mans ability to adapt and acclimatize to high altitude cold the physical characteristics of four groups of individuals were correlated to their body temperature responses when exposed to an ambient temperature of 14 degrees C. for two hours at an altitude of 3760 meters. The body characteristics chosen for analysis were, age, standing height, sitting height, weight, % body fat, fat free weight and sum of skinfold. The four groups were U.S. Whites, University of Cuzco White and Indian students and native Indian villagers. The results showed significant association between body characteristics and body temperatures in all groups. Fat acted as insulation in all groups and fat free weight had very significant positive effects on total body heat content. The total body heat content of native Indian villagers was more significantly affected by age than in other groups and fat-free weight in this group had a strong effect on peripheral body temperatures. The results agree with the suggestion made in the previous progress report that native Indian villagers have a higher metabolic response to cold stress.
