In 2010 Scurr, White and Hedger conducted a second study on the effect of breast support on the movement of the breast during the running gait cycle. The aim of this study was to investigate the multi-directional breast displacement, velocity, and acceleration with and without breast support during running and also to establish the correlation with breast comfort. Fifteen women who wore D cup sized bras and regularly participated in exercise took part. Using treadmill running in three different bra conditions (no bra, T-shirt bra, and sports bra), they concluded that breast displacement and velocity were reduced as breast support increased and that no particular direction of breast movement showed a stronger relationship to breast pain. Further to this they found that breast discomfort was most closely correlated to breast velocity.
