摘 要:探讨C罩杯女性的乳房运动规律,比较女性在乳房受文胸作用下其运动受到控制时乳房的运动特征,为保护乳房和运动文胸的设计提供理论依据。运用美国Motion Analysis红外光动作捕捉系统测试8名C罩杯女性在走(4 km/h和6 km/h)和跑(8 km/h和10 km/h)过程中裸胸及穿运动文胸状态下躯干及乳房的运动学特征,采集频率为200 Hz。结果表明:着运动文胸相比裸胸,乳房上各点运动振幅的数值均有显著减小;随着运动速度的增加,乳房的运动幅度在3个方向上都逐渐增大;乳房上各部位的运动特征不同,研究乳房运动时应对乳房上多个位置进行测试,乳头点不能代表整个乳房的运动。得出结论:运动文胸很好地控制了乳房的运动,尤其是左右方向和垂直方向的运动。

Abstract:Purpose:To investigate the breast movement of Ccup women,to compare the effects of sports bras on breast movement and to provide theoretical support for bra designers.Methods:8 Ccup women subjects performed walking (at 4 km/h or 6km/h) and running (8km/h or 10km/h) activity on the treadmill with sports bras and no bra respectively with Motion Analysis.Their breast movements are captured using a sixcamera motion analysis system with 200Hz sampling frequency.Result:Sports bra has a better support to breasts and the magnitude of displacement reduced with increasing breast support.The value of the displacement of the breasts in running at 10km/h and 8km/h is significantly greater than that of walking at 6km/h and 4km/h.More than one part of the breast should be tested in the future studies since the characteristics of different breast parts are different,and the breasts cannot be repented solely by the nipples.Conclusions:Sports bra has a better impact on the displacement of different markers,especially in mediolateral and vertical movements.
