Women jogging should wear sports bra

Russian tennis player Anna Kournikova has been at the forefront of a campaign to advise women to wear sports bra

Millions of women jogging exercise can suffer from a breast if not wearing a proper bra, according to researchers at the University of Portsmouth, England.

Scientists found that when women jog, their breasts moved in a three-dimensional figure and this uncontrolled movement dilated delicate tissues and ligaments. The study showed that when a woman ran 1km, her breasts bounced and measured about 84m. In other words, each breast moves independently with the body averaging 9cm each step.

With an average breast weighing 200-300 grams, this movement puts great pressure on the delicate background of the breast - epidermis and connective tissue (Cooper ligament). The team found that the movements of the breasts lead to temporary pain and discomfort. But it can also cause constant pressure on Cooper ligaments, making the breast irreparable. They said wearing a normal T-shirt bra reduced the breast by 38%, but wearing a sports bra could reduce this movement by 78%.
