Breast pain is common during exercise, occurring in up to 56% of subjects in some surveys. This pain is mainly associated with the movement of breast tissue. In an attempt to analyse this movement and the resulting pain, the movement of the female breast tissue was quantified in four conditions of breast support ("sports bra", "fashion bra", "crop top" and bare breasted) during four different activities (running, jogging, aerobics march and walking). These activities represented general patterns of exercise for adult females in Australian society. All three subjects were healthy, active, young women of varying breast size (12B, 14B & 14C) that were typical of young women. Two of the subjects had noted breast pain whilst exercising. The results showed that wearing external support for the breast tissue reduced absolute vertical movement and maximum downward deceleration force on the breast. Support also reduced perceived pain. When compared to other forms of breast support a "sports bra" (brassiere designed for breast support whilst exercising) provided superior support for the breast in relation to the amplitude of movement, deceleration forces on the breast, and perceived pain. The data indicates that adult females should wear appropriate breast support to reduce perceived breast discomfort or pain. Of the three garments examined in this study, the fitted sports bra provided superior support and pain reduction.
运动期间乳房疼痛很常见，在一些调查中，高达56%的受试者会出现这种情况。这种疼痛主要与乳房组织的运动有关。为了分析这种运动及由此产生的疼痛，在四种不同活动（跑步、慢跑、有氧健身操行进和步行）期间，对女性乳房组织在四种乳房支撑条件（“运动胸罩”、“时尚胸罩”、“露脐短上衣”和裸胸）下的运动进行了量化。这些活动代表了澳大利亚社会成年女性的一般运动模式。所有三名受试者均为健康、活跃的年轻女性，乳房大小各异（12B、14B和14C），是年轻女性的典型代表。其中两名受试者在运动时曾注意到乳房疼痛。结果表明，为乳房组织提供外部支撑可减少乳房的绝对垂直运动和最大向下减速力。支撑还能减轻疼痛感。与其他形式的乳房支撑相比，“运动胸罩”（专为运动时支撑乳房设计的胸罩）在运动幅度、乳房减速力和疼痛感方面为乳房提供了更好的支撑。数据表明，成年女性应佩戴合适的乳房支撑物，以减轻乳房不适或疼痛感。在本研究中检测的三种服装中，合身的运动胸罩提供了更好的支撑并减轻了疼痛。
