None of the subjects were weight lifting athletes or did regular physical exercises. The measurements of skin-fold and girth were taken by an expert in the field. Measurements of Skin-fold: Recommendations published by the committee on nutritional, Anthropometry of the Food weight lifting and Nutrition Board of the National Research Councils[8] were followed. A Lange's calliper was used with a constant calliper pressure of 102 g/MM2. The calliper had rectangular jaw faces measuring 40 mm. Three to five replicate measurements were taken on the right side of the body with subjects standing and mean of this was expressed as weight lifting skin-fold score. The skin-fold thickness was measured to the nearest mm. except for low values (usually less than 5 mm or less), in which case it was taken to the nearest 0.5 mm. Four sites chosen were biceps, triceps, sub-scapular and suprailiac. Body density in gms/cc derived from the sum of these four skin-fold thickness scores using the equations of Durnin and Wornersley[9].
