Abstract
This study aims to compare chest mobility, diaphragm contraction, and lung capacity when wearing a bra and per breast size. The subjects of this study included 10 adult women who were attending Chungnam B University: 5 women who wear underwear size 75A (group A) and 5 who wear underwear size 85B (group B). The chest mobility using a tape measure, the diaphragm contraction using ultrasound, and the lung capacity was measured using a Pony FX before and after bra wear. The chest mobility and diaphragm contraction were significantly reduced when bras were worn in group A and B. Lung capacity was significantly decreased only in group A. There was no significant difference between the groups. This study suggests that women's bras can have a negative effect on diaphragm movement, chest mobility, and lung capacity.
