The Grey Lady looks into whether breast movement impacts running form is a question of serious scientific inquiry.
Researchers from the University of Portsmouth in England and other schools recently attached reflective markers to the breasts of a group of female runners and had the women jog along a track while wearing various types of bras or forgoing breast support. The researchers charted the trajectories of the women’s breasts, using infrared cameras.
The researchers conclude: Yes, they have an impact and "[instead] of merely bouncing up and down, it turns out that breasts arc through a complicated figure-8 pattern when a woman runs or walks."
My head just reflexively moved in a figure-8 pattern.
