To clarify the characteristics of breast vibration and brassiere dislocation during running, movements of five spots on the breast surface, that of the same five spots on transparent brassieres after removing brassiere caps to visualize the breast surface, and the clothing pressures of the corresponding five spots were simultaneously monitored using an image analyzing system. The subjects for our experiment were young women with had hemispheric breasts. Obtained data of those movements and pressure were analyzed using the discrete Fourier transform. The breasts in a brassiere were vibrated at the same frequency of running. The dislocation of the brassiere from the breast surface which was observed was associated with changes in the clothing pressure at the lower half of the brassiere. Vibration of the breasts of the subjects wearing spots brassieres was move obvious in the vertical direction, while vibration of the breasts of the breasts of the subjects wearing full-cup brassieres was more obvious in the horizontal direction.
