Bionic bra: Victoria’s circuit
An attempt to harness, as it were, the kinetic energy stored in the ones that bounce.
It turns out that the physics of breast motion has been studied closely for the last two decades by a gamut of researchers – most of them women.
Formally, perhaps.
Lawson explains that breasts move on three different axes: from side to side, front to back, and up and down. The most motion is generated on the vertical axis. Naturally, the bigger the breast, the more momentum it generates. “Let’s face it – if you’re a double-A marathoner, you’re probably not going to get that iPod up and running,” Lawson says. Measurements compiled by Lawson and her colleagues show that a D-cup in a low-support bra can travel as much as 35 inches (89cm) up and down (35 inches!) during exercise, while a B-cup in a high-support bra barely moves an inch.
Again, something that a motivated amateur scientist might have also observed.
