The influence of age, physical activity and altitude on the body composition


, : The influence of age, physical activity and altitude on the body composition. Arch Inst Biol Andina [lima] 1(3): 119-127

Simultaneous determinations of total body water and extracellular fluid, using the antipyrine and sucrose infusion methods, were carried out in 28 adult male residents at an altitude of 4,540 meters above sea level. Body composition was calculated from these data. The various body spaces, expressed in percentage of body weight, were similar in high-altitude group (P < .01). Neither racial characteristics nor altitude appear to be factors generally affecting body composition. In individuals having adequate caloric intake body composition seems to be influenced principally by physical activity.

It has been proposed that eukaryotic repressors of transcription can act by organizing chromatin, thereby preventing the accessibility of nearby DNA to activator proteins required for transcription initiation. In this study, we test this idea for...
