摘要：

为研究钢圈是否能有效提高文胸对运动时女性乳房竖直位移的控制作用,使用三维运动捕捉系统(NDI Optotrak Certus)采集了9名C罩杯女性分别穿着有钢圈文胸和无钢圈文胸时以3种速度(5,7.5,10 km/h)在跑步机上运动时的乳房竖直位移数据;同时,使用视觉模拟评分表测量实验对象在每个状态下的主观乳房位移及乳房位移引起的不舒适感。结果表明:加钢圈可显著提高文胸对C罩杯女性在跑步机上运动时乳房竖直位移的控制作用;加钢圈可降低实验对象因乳房位移引起的不舒适感;有钢圈文胸相对于无钢圈文胸对乳房竖直位移控制效果随运动速度增加而增强。

关键词: 乳房位移, 文胸钢圈, 运动状态, 三维运动捕捉

Abstract:

In order to study whether adding underwire can effectively improve limitation of bra on women's vertical breast displacement during exercise, three dimensional motion capture system (NDI Optotrak Certus) was employed to collect the vertical breast displacement of 9 participants with the breast size of C cup, when they were wearing bras with and without underwire, exercising on the treadmill at three gait speeds (5, 7.5, 10 km/h). Meanwhile, visual analogue scale (VAS) was adopted to measure participants' perceived breast displacement and discomfort resulted from breast displacement in each motion state. The results show that adding underwire can effectively increase bra function on limiting vertical breast displacement of women with C cup size breasts when they are exercising on the treadmill. Similarly, adding underwire has a significant effect on reducing participants' perceived breast displacement and discomfort related to breast displacement. The control effect of underwire on vertical breast displacement increases with the acceleration of gait speed.

Key words: breast displacement, bra underwire, motion state, three-dimensional motion capture
