Abstract : "The effects of 10-month stay at high altitude (HA) on body composition of Indian soldiers of mix ethnic origins with special reference to body musculature were investigated. Body density was regressed from skinfold thicknesses and girth measurements. Bone mineral was estimated from body width and stature. Muscle X-ray shadow areas at upperarm and forearm and stature were correlated with body mass and a regression equation was constructed. Analysis of data indicated that muscle mass degraded at HA. In soldiers of group I (height: 4100 m), 1.74 kg muscle mass degraded to generate 1.31 kg water. In soldiers of group 2 (height: 3750 m ), 1.38 kg muscle mass was degraded to generate 1.04 kg water.

Abstract : 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.

Abstract : The paper describes how anthropometric data obtained on 4400 Indian Army personnel was utilized in evolving size rolls for the trousers and shirts. A bivariate frequency distribution of abdominal circumference and abdominal height indicated that the data could be grouped into 14 sizes and such grouping could provide good fitting trousers to 92.52 percent of the troops. For shirts, the bivariate frequency distribution of chest circumference and arm length grouped army personnel again into 14 sizes. Such grouping encompassed 84.22 percent of the personnel studied. An extra large size has been provided for those not covered by these 14 size. In this study, 95 army officers' clothing measurements essential for their good fitting trousers and shirts were taken along with the relevant body measurement. A stepwise linear regression analysis was also carried out to predict clothing measurements from body measurements. These regression equations were used to work out the dimensions of the trousers and shirts for different sizes from the classified anthropometric data.
