| Popis: | Body density, stature, body weight and skinfold thickness at 11 sites were experimentally measured on two groups of high altitude natives (HAN) of Ladakh. Group 1, consisting of 38 similar volunteers was studied after 4-week stay at an altitude of 3658 m and Group 2, consisting of 38 similar volunteers was studied after 4-week stay at Delhi (altitude, 200m). Although, there was a strong relationship between skinfolds, other anthropometric measurements and body density (R=0.898) at high altitude (HA), this relationship was significantly reduced at Delhi (R=0.642). Appropriate regression equations predicting body density from skinfold thicknesses, stature and body weight are given for HAN at both the locations. It is concluded that hyperhydration of the lean body and the adipose tissue may be responsible for the weakening of the multiple Rs on de-acclimatisation to low altitude. |
