In this study, the dynamic changes in human body shape according to movement have been analyzed using three-dimensional scanning system. For this, 12 male subjects were scanned in six postures and the amount of changes in 32 anthropometric measurement items were examined. As for the height items, all items changed in walking pose, and for the length items, the shoulder and chest lengths were affected by arm movement. For circumference items, considerable changes were observed in the chest and waist region according to the movement. A body cross section analysis software has been developed to analyze the change in body shape according to movement in various perspectives. As a result, the chest region was found to be affected by the movement of the arms, the waist region by the movement of the trunk, and hip region was by the movement of the leg.
