This study aimed to determine the bra-breast forces generated in women with large breasts while these women wore different levels of breast support during both upright standing and treadmill running. The mean bilateral vertical component of the bra-breast force in standing was 11.7 ± 4.6 N, whereas during treadmill running the mean unilateral bra-breast force was 8.7 ± 6.4 N and 14.7 ± 10.3 N in the high and low support conditions, respectively. Furthermore, breast mass was significantly correlated with vertical breast displacement (R(2) = 0.62) in the high support condition. The wide range of breast masses of women with large breasts is an important consideration for designers of sports bras to ensure these bras can reduce force generation and breast discomfort by providing a high level of breast support while these women participate in physical activity.
本研究旨在确定大乳房女性在直立和跑步机跑步时穿着不同程度的乳房支撑时产生的胸罩-乳房力。站立时双侧垂直胸罩-乳房力的平均值为 11.7 ± 4.6 N，而在跑步机跑步时，高支撑和低支撑条件下单侧胸罩-乳房力的平均值分别为 8.7 ± 6.4 N 和 14.7 ± 10.3 N。此外，在高支撑条件下，乳房质量与垂直乳房位移显著相关（R(2) = 0.62）。大乳房女性的乳房质量范围很广，这是运动胸罩设计者的一个重要考虑因素，以确保这些胸罩在女性参加体育活动时通过提供高水平的乳房支撑来减少力的产生和乳房不适。
