A PRELIMINARY STUDY OF BREAST MOVEMENT IN DIFFERENT BRA SUPPORT

Abstract

To free women involved in physical activities from suffering breast pain due to insufficient breast support, thorough understanding of the breast displacement mechanism is needed. The study is aimed to determine the true movement of the breast in three types of bras, and ultimately, to build a scientific base for bra design improvement. 28 female participants were recruited and the breast movements in four different types of breast support were recorded using the electromagnetic tracking system for further analysis. The results showed that the trajectories of left and right breast in a crop-top bra for the lateral raise showed significant difference (p =.039). The effect of sportsbra was obvious in all four movements and the breast displacement decreased as the breast support level increased (from non-sportsbra to sportsbra).
