Many women will tell you that large breasts are an impediment to exercise, both in terms of discomfort and embarrassment. According to a study of 20 women with C+ breasts in Medicine & Science in Sports & Exercise (MSSE), sports bras which provide breast encapsulation, compression, and elevation (whereas traditional sports bras only provide compression and encapsulation) are more comfortable during physical activity. Breast motion tracking was done via “infrared light-emitting diodes (2-mm diameter)…placed directly on both nipples under each bra using double-sided surgical tape, as the nipples have been found to be the best indicator of vertical breast displacement.”
From the abstract:
Results: Exercise-induced breast discomfort (P < 0.01) and bra discomfort (P < 0.01) were significantly less for the experimental bra condition relative to the sports bra and placebo bra. This reduction in discomfort was achieved through greater breast elevation (P < 0.01) and compression, with no difference found in vertical breast displacement (P = 0.12) or vertical breast velocity (P = 0.06). Conclusions: The design features of greater breast elevation and compression provided significantly increased breast and bra comfort compared with a standard encapsulation sports bra during physical activity for women with large breasts.
