The study suggested as a woman runs a mile, her breasts bounced 135m.
I hope this doesn't happen to men too, otherwise a couple of my friends are in for a droopy surprise later in life.
They claim that wearing an ordinary T-shirt bra reduced bounce by 38%, but wearing a sports bra by the firm Shock Absorber - which sponsored the research - reduced bounce by 78%.
Where's the fun in that?
Anna Kournikova led a campaign to get women wearing sports bras
I thought Nike was already paying Brandi Chastain to do that.
