胸部位移与文胸舒适性关系初探

Preliminary study of effect of breast displacement on bra comfort

为考察胸部位移与舒适性之间的关系。分别以裸体、穿着3/4文胸和穿着运动文胸状态以5 km/h和10 km/h的速度在跑步机上跑步,用VICON运动学测量分析系统捕捉测试者各轴向上的胸部位移值,并要求测试者对各状态下的文胸舒适性进行主观评价。结果发现,跑速与胸部位移正相关;胸部位移与舒适感负相关,垂直轴向上的波幅是影响舒适性的主要因素;对比3种穿着状态,运动文胸能够限制胸部垂直方向上的位移,改善胸部舒适性。

An investigation into the effect of breast displacement on comfort measured the values of breast displacement of different directions of the subjects when they were running on the treadmill at a speed of 5 km/h or 10 km/h respectively under different conditions,i.e.,bare breast,wearing 3/4 cup size bra,and wearing sports bra by using VICON motion analyzer,and the subjects were requested to give their subjective evaluation of the bra comfort under individual conditions.It was found that running speed had positive correlation with breast displacement;breast displacement had negative correlation with comfort,amplitude of vertical breast displacement was the main factor affecting comfort;and the sports bra could limit the vertical breast displacement,and therefore improved the comfort of the breast.
