Exercise bounce harms breasts -

Scientists urge you to wear a sports bra for proper support

When you engage in sports, you may occasionally struggle against bad weather or even your own inner voice tempting you to chill out on the sofa instead of exercising. But are you aware that your real enemy is most likely an invisible force?

"While the lucky ones will see an improvement in their legs, bums and tums, the vast majority run the risk of accelerating the effects of gravity on their breasts"

This is reported by a new study at the University of Portsmouth, UK. The British scientists estimate that almost 80% of women currently taking regular exercise do not protect their breasts properly.

The report found that breasts move in a three dimensional figure of eight: With the average breast (cup size 36C) weighing between 200-300 grams, this uncontrolled movement puts great strain on the breasts. During each step taken on a treadmill, the average breast moves, independently of the body, by an average of nine centimetres (going up and down, in and out and side to side) while breasts in a G-cup bounce up to 14 centimetres.

The breast's natural, but fragile support structure is made up of fatty tissue. The breast is held onto the chest wall by Cooper's ligaments. Over a period of time these ligaments stretch if the breasts are not supported. Not only will this cause pain and discomfort but more importantly will lead to irreversible breast sag (some quicker and some more often than others).

Wearing a T-shirt bra during exercise reduces bounce by an average of 38%. However, to prevent breast sag, Dr.Joanna Scurr, who carried out the research, urges women to wear a proper sports bra when exercising asbreast bounce may be reduced by up to 74%.
