Have you ever know that the vertical movement of the chest can exceed 70mm (almost three inches) during vigorous effort while doing sports or jogging, and bra scientists say the stresses and strains from the movements can affect nerves around the shoulders so seriously that it causes numbness in fingers.

Better support is needed because the female breast contains no supportive muscle or bone. Recent study by researcher Joanna Scurr at the University of Portsmouth in England found more than 50% of women experience breast pain while exercising. This could happen because many bras fail to offer proper support and they do not adapt to side-to-side movement.

The other research at the University of Wollongong, in Australia, scientists designed a special fabric with sensors to detect movement as women walked and jogged on a treadmill. They researchers say the future bra designs must limit excessive breast movement without causing discomfort.

“It is imperative that brassiere designers have access to methods that can accurately and reliably quantify the effects of various brassiere design features on breast motion while not altering the material properties of the brassiere,” they say.
“However, most commercially available technologies have traditionally been comprised of rigid parts, such as strain gauges or buckle transducers, which can interfere with performance.”

Meanwhile, Joanna Scur from the University of Portsmouth found the clue help prevent pain, which is wearing the right type of bra. That type of bra, should has separate molded cups, in contrast toa compression bra, which flattens the breasts against the chest wall.

“Our research has shown encapsulation sports bras to be more effective at reducing breast motion,” Scurr says.

Recently other scientists have developed an “intelligent fabric” with its own sensors that can be used to design bras for women with more accurately in the hope of putting an end to the discomfort and even long-term injury that can result from poor bra design.
