跑步运动中运动文胸对乳房振幅的影响

为考察运动文胸的防震效果,以及穿着运动文胸时的感受情况,使用相同面料,制作了统一尺寸、厚度相近的7款运动文胸。运用三维动作捕捉仪,测试实验者在裸胸状态以及穿戴7款运动文胸在跑步运动中胸部移动状况。通过乳房相对躯干的位移极差值和穿戴文胸前后的位移减少百分比,运用SPPS软件进行数理统计,比较运动文胸的防震效果,并结合主观实验进行综合分析。同时,在现有运动文胸款式的基础上对其造型设计提出改进建议。结果表明:文胸背部设计成交叉款式的防震效果较好,同时肩带加宽,可减少肩部的压强,提高穿着舒适度。

Effect of sports bra on breast displacement amplitude during running

Aimed to investigate the shock-proof effect of women′s sports bra and its wearing comfort,this study experimented on 7 types of sports bras made from the same fabric with similar size and thickness.With the help of 3-D motion capturing instrument,data on chest movements in bare chest as well as in running wearing of different sports bra were collected.According to the extreme difference of displacement amplitude of the breast relative to the trunk along with the percentage reduction in breast displacement before and after wearing,SPSS software was used for mathematical statistics to compare the shock-proof effect of sports bras,along with the subjective experiments to make comprehensive analysis.Suggestions are put forward to improve the modeling design of sports bra,which provides reference to the bra manufacturers for the development and production of sports bras.The result shows that the bras with crossover back design has the best shock-proof effect.On the other hand,widening the shoulder belts can reduce the pressure on the shoulder and improve the level of comfort.
