Breast Power

When I saw this on MSN just now I knew it was too good to pass up as a blog entry. LOL Seems that companies want to take environmental consciousness to a new and quite personal level. But my question is… what about the women with A and B cups? They don’t exactly have the momentum required…

It turns out that the physics of breast motion have been studied closely for the last two decades by a gamut of researchers, most of them women. LaJean Lawson, a former professor of exercise science at Oregon State University, has studied breast motion since 1985 and now works as a consultant for companies like Nike to develop better sports bra designs. Lawson was enthusiastic about my idea but warned it would be tricky to pull off. You would need the right breast size and the right material, she explained, and the bra itself would have to be cleverly designed. “It’s just a matter of finding the sweet spot, between reducing motion to the point where it’s comfortable but still allowing enough motion to power your iPod,” she said.

See? This isn’t exactly an equal opportunity energy saver…

Lawson explained 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. Measurements compiled by Lawson and her colleagues show that a D-cup in a low-support bra can travel as much as 35 inches up and down (35 inches!) during exercise, while a B-cup in a high-support bra barely moves an inch.

Now I know why I don’t jog….

But then again, this seems like an impossible venture considering that the aim of most sports bras is to limit breast movement, not enhance it.

Anyway, you can read the entire story at Slate. I just found it highly amusing.
