Abstract:
Human modeling and the biomechanical analysis of human movement require the accurate estimation of body segment parameters for various populations and individuals. In this study, the body characteristics of adult Koreans were investigated using three-dimensional range scan data for 40 males and 40 females aged between 18 and 59 years obtained from the SizeKorea anthropometric database. Each subject was divided into 16 segments, and the mass-inertial parameters of each segment were calculated under the assumption of a uniform density distribution for the segment. The length and at least one circumference of each segment were determined from the scan data for that segment. Nonlinear regression equations were then derived based on the segment lengths and circumferences. The body segment parameters of Korean adults can be estimated using these equations if the required dimensions are measured directly or derived from an anthropometric database.
