| This study employed 3-D scanner to measure 26 and 20 items of lower-body size and surface length respectively when 13 women with ages from 20 to 24 normally walked, went up stairs and sat down on chairs so that the changes to body-surface length at each movement might be estimated. While the front-side leg [waist to knee] length and back-side leg [waist to popliteal] length at normal walking showed both extension and contraction, only the inside leg [waist to knee] length had contraction and the outside leg length did not, which is compared with the measurements at standing position. At stair-climbing and sitting position, the front waist circumference, the front hip circumference, the front knee circumference and back crotch length extended, while the back calf circumference contracted at stair-climbing. On the other hand, the sitting posture showed the extension of the back calf circumference. At the sitting position, outside leg [thigh to knee] length did not show any change to the body-surface length. The parts commonly having the changes to body-surface length at those three movements were front-side leg [waist to knee], backside leg[waist to popliteal] and, inside leg[thigh to knee], while those without change to the length were back waist circumference, front waist circumference (omphalion), back waist circumference (omphalion), front mid-thigh circumference, front calf circumference and front ankle circumference. The items showing both extension and contraction of body-surface length at movements were front-side leg[waist to knee], backside leg[waist to popliteal] and inside leg. Those with any difference at those lengths at movements were found to be front knee circumference, back knee circumference, front crotch length, back crotch length, front-side leg length, backside leg length, outside leg length and inside leg length. |
