胸部位移与文胸舒适性关系初探

为考察胸部位移与舒适性之间的关系，设计一组实验。分别以裸体、穿着3/4文胸和穿着运动文胸状态于5 km/h和10 km/h的跑速在跑步机上跑步，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；对比三种穿着状态，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。本文为文胸舒适性的客观评判提供了一种可行的方法。

Preliminary study of effect of breast displacement on bra comfort

To study the effects of breast displacement on comfort, the To study the effects of breast displacement on comfort, the experimental procedure was designed. The subject was filmed by VICON motion analyzer while ran on the treadmill at 5 km/h and 10 km/h in bare breasted, 3/4 cup size bra and sports bra condition. Subjective data was collected immediately after the treadmill running trials. And from the result we obtained 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; the sports bra provided limited vertical breast displacement and pain reduction. This research provided an available approach for studying the bra.
