Abstract

The validity of the “segment-zone” anthropometric method for calculat­ing segmental volume was studied for the limbs, and head and neck in 23 female (mean age, 21 yr; mean weight, 54 kg) and 24 male (mean age, 21 yr; mean weight, 76 kg) subjects. The arms and forearms were viewed as a series of 3 truncated cones, thighs and legs a series of 4 truncated cones, hands and feet as wedges, head as a sphere, and neck as 1 truncated cone. The necessary girths and zone heights were obtained for each zone for use in calculating the respective zone volumes using appropriate geometric formulae. The validity of this technique was computed as the correlations between the calculated segmental volume versus the segment volume obtained by water displacement (criterion volume). All the validity coefficients were significant at the .01 level, except for the head and neck for males and females and right and left foot for females. In addition, the only significant difference found between the mean calculated and the mean criterion segment volumes were for the hands and feet and head and neck for both males and females. Multiple linear regression equations were computed using the anthropometric data to predict the criterion segmental volumes. The validity of these equations was reported for a separate sample of subjects.
