This document, authored by Charles E. Clauser, John T. McConville, and J. W. Young, provides a comprehensive study of the weight, volume, and center of mass of segments of the human body. The study aims to supplement existing knowledge and allow more accurate estimation of these parameters from anthropometric dimensions. Thirteen male cadavers were dissected into 14 segments, and their weight, volume, and center of mass were determined. The relationships between segment size, weight, volume, and center of mass are used to estimate these parameters for living populations. The study was conducted under Project 7184, "Human Performance in Advanced Systems," and involved collaboration between the Aerospace Medical Research Laboratory, Antioch College, and the Civil Aeromedical Institute. The research was supported by the National Aeronautics and Space Administration. The historical background section reviews previous studies on the weight, volume, and center of mass of the human body, highlighting techniques used by early researchers such as Borelli, Weber, Harless, and Braune. These studies laid the foundation for more recent work, including those by Bernstein, Dempster, and Drillis and Contini. The methods and techniques section describes the procedures used in this study, which involved selecting preserved cadavers based on criteria such as age, physical appearance, and evidence of pre- or postmortem wasting. The cadavers were treated with a preservative solution to maintain their weight and volume, and the segments were measured using established techniques. The study concludes with a discussion of the limitations of different approaches, including the use of live subjects, cadavers, and mathematical models. It emphasizes the need for further research to predict body segment parameters accurately from anthropometric dimensions and to validate these predictions for individuals and populations.This document, authored by Charles E.
