EVALUATION OF BREAST SUPPORTS WITH DIFFERENT BRAS DURING JUMPLANDING MANEUVERS

Abstract

This study attempted to evaluate kinematic of the breast with different breast support during jump-landing maneuvers. Twelve C cup female volleyball athletes were recruited in this study. Markers were attached to the subject’s nipples and trunk to calculate relative 3D breast kinematics data. The subject had to wear four kinds of bras (no bra, normal bra, fashion bra, and sport bra) to evaluation of breast support in the medio-lateral, anterioposterior, and vertical directions. Results of current study showed that the sports bra was effective in reducing the amplitude of breast displacement, velocity, acceleration, and comfort scale during jump-landing than no bra situation, everyday bra, and fashion bra. Future studies should be focus on analyzing different types of sports bras in order to identify 3D breast kinematics with different bras during jump-landing maneuvers.
