Description

For clothing and body design that fits the body shape, posture and actions of elderly women, an investigation was made into the body trunk shape changes in standing and sitting postures, and the body shape characteristics in sitting posture were ascertained. Subjects were 30 elderly women aged 65-80. Three-dimensional (3D) scan data was used for analysis. From the dimensional changes of the body trunk according to posture, it was shown that, compared to standing posture, elderly women in sitting posture have a tendency to be more inclined and bent forward, and have a larger abdominal region. From the results of principal component analysis of the shapes, more than 80% of the body shape characteristics of elderly women in sitting posture could be explained by a forward bending of the back, abdominal protuberance, a balance between height dimensions and circumference/width dimensions, and fatness. It was clarified that there are major differences in abdominal shapes between standing posture and sitting posture.
