The purpose of this study was to clear the change of the shape of the calf by contraction of triceps surae muscle. For the female university students, with the aid of moire topography, it was taken some anthropometrical measurements of the shape of the calf at the time of passive contraction and at the time of active contraction.The result is as follows:1)The calf girth increased with contraCtion of triceps surae muscle.2) The ankle girth decreased at the time of passive contraction, and it increased at thetime of active contraction on the contrary.3) The position of the most projected point of the calf moved upward with contraction of triceps surae muscle.4) Though the muscle venter swelled with contraction of triceps suraemuscle, the quantity of projection of the calf decreased relatively.
