During the transition phase from walking to running, bounce increases rapidly, then levels off
The implication of this is that you simply need a Bra for physical activities just as much at lower running speeds as at high speeds. Like women’s shoes and clothes, the science behind sports bras has raced ahead in recent years.
Bra for physical activities
Manufacturers of sport bras have increased the levels of support offered by their clothes to prevent women from damaging their breasts during running.
Something of a surprise
Many women nonetheless avoid a decent sports bra in favour of an everyday variety – or, sometimes, nothing at all.
Science behind bras
Research carried out by the Shock Absorber Sports Institute (SASI) at Portsmouth University discovered that the prospect of irreversible breast sag faces the 9.5 million British women, out of the 12 million currently taking regular exercise, who don’t protect their breasts properly. During exercise, research has shown that breasts move in a three-dimensional movement, going up and down, in and out, and side to side.
Weight and skin
With the average 36C breast weighing between 250-300grams, this movement puts great pressure on the breast’s fragile support structure, which comprises only the outer skin and connective tissue known as Cooper’s ligament. Breast movement may cause the Cooper’s ligaments to stretch and this can result in irreversible damage to the breasts.
Wearing a regular bra during workout reduces bounce by an average of 38%. However, a properly fitted sports bra reduces breast bounce by up to 74% – almost twice as effective at minimizing breast motion as an everyday bra.
Wear the right equipment and protect yourself from possible damage.
