Objective To set up the multiple regression equation that could immediately calculate the segmental move inertia of the Chinese young male bodies by determining the data of move inertia of the segments and the mathematical model. Methods By using the CT-DIP method in this project , to carry out the determination for 50 Chinese young male living subjects (18～23 year-old) on their posture parameters , the scanning , image analysis , calculation , and progressive regression so that to choose and define the important variable quantities. Results A series of the data on move inertia of the segments were obtained and set up the mathematical model consisted of 15-segments. The multiple regression equation was then established which could immediately calculate the move inertia of the segments of the Chinese young male bodies, in which the body weight , the stature , and the segmental length , the wide, and the contour were usedas independent variable quantity. Conclusion This study provided the dependable means to calculate immediately the move inertia of the segments of the Chinese young male bodies .
