Anthropometric Relationships of Body and Body Segment Moments of Inertia

Abstract
This report documents the results of a study aimed at demonstrating that mass distribution properties of the human body and its segments can be predicted from anthropometric dimensions. Investigators combined stereophotometric and anthropometric techniques to measure 31 male subjects. Bodies were photographically segmented into 24 parts and their volume, centers of volume and principal moments of inertia established stereometrically. Principal moments were measured about three principal axes of inertia which were established with reference to anatomical axis systems based on easily located body landmarks. Seventy-five body size variables were measured anthropometrically and an additional 10 dimensions were derived from the measured variables. Multiple regression equations were devised for the total body and for each segment using the most highly correlated variables on each segment, and stature and weight for determining volume and principal moments of inertia. Included is a brief review of the literature with emphasis on earlier studies by authors which provide the rationale for the reliability of the stereophotometric method in determining mass distribution properties of living subjects.
