Research on the Asymmetry of the Left and Right Breast during Walking
To investigate kinematic characteristics and asymmetry of the left and right breast ,to protect the breast better and to provide theoretical support for bra designers .Methods:12 healthy C‐cup females were invited to perform walking activities under braless and a sports bra condition .The subjects per‐formed walking activity on a treadmill at the speed of 6km/h .Their breast movements were captured u‐sing a ten‐camera Qualisys Motion Capture System with 200 Hz sampling frequency .Result :the trajecto‐ries of the left and right breast under braless and a sports bra condition showed a similar shape ,the differ‐ence of displacement of the left and right breast was larger under braless conditions than that of the sports bra conditions .Conclusions :There were significant differences in the displacement of the left and right breast under braless condition .The magnitude of displacement of the left breast was significantly larger than that of the right breast .Sports bra can reduce the difference between the displacements of both sides of the breast .Reduced percentage of the left breast displacement was significantly larger than that of the right breast .
