Oscillation Reduction of Breast for Cup-Pad Choice

Traditional studies of evaluating breast displacement included cup fabrics,shoulder straps,and under-bands restricted by own features of sports bras(SBs).The effects of pads on breast support during movement were investigated by conducting trials with the motion capture experiment.The three-dimensional breast displacements at five breast positions were collected and values in the vertical direction were evaluated.Results indicate that the effectiveness of the cup pad depends on the pad diameter and the thickness.SBs with larger pads and thicker pads made of soft polyurethane cause less overall breast displacement during vertical jumping compared to unpadded bras(p<0.05).The effectiveness of bra oscillation reduction was characterized by the total reduced percentage of the breast displacement.These findings enlarge scopes in terms of the current breast displacement analysis and understanding of selecting SBs associated with changes in the specifications of pads,thereby providing objective methods for bra cup evaluation and a design basis for breast protection.
