title: Breast elevation and compression decrease exercise-induced breast discomfort.
abstract: OBJECTIVE
  The aim of this study was to investigate whether a sports bra designed to both elevate and compress the breasts could decrease exercise-induced breast discomfort and bra fit discomfort experienced by women with large breasts relative to a standard encapsulation sports bra.
  
  
  METHODS
  Breast kinematic data, bra fit comfort, exercise-induced breast discomfort, and bra rankings in terms of preference to wear during running were compared in 20 women with large breasts who ran on a treadmill under three bra conditions: an experimental bra that incorporated both breast compression and elevation, an encapsulation sports bra, and a placebo bra. Subjective data were collected immediately before and after the treadmill running trials.
  
  
  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.
