Exercise usually results in a large displacement of the breasts, often lead
ing to breast pain. Although breast pain is a common concern of exercising
females, little research has been conducted in the area of breast pain. It
has been suggested that a cause of breast pain is excessive breast motion.
As the female breast does not contain strong intrinsic structural support,
this breast motion is difficult to reduce. It is suggested that the primary
anatomical support for the breast is the Cooper's ligaments; however, thei
r true functional properties are unknown. Because of the lack of internal b
reast support it has been suggested that the skin covering the breast may a
lso act as a support structure for the breast, but this has not been quanti
fied. In an attempt to reduce breast motion, external breast supports (bras
sieres) have been developed. This article discusses components of current s
ports brassieres with implications for future research required to improve
brassiere design and performance.
