Article from the NY Times that says that improper breast support could potentially cause injury -- not just to the girls, but to the rest of the body -- by throwing off body mechanics:

It turns out my sad little A-cups are good for something...

That's really interesting! Thank you for posting

As a side note, that completely confirmed a complaint I had had for years. Running is more difficult with large breasts and an improper sports bra. When I was in high school soccer, we had to run a LOT. And even if I trained just as much as everyone else, or more, I was still one of the worst runners. I always thought it was because I had large breasts, but people laughed that off. Now that I think of it, the 3 worst runners on our team had large breasts. Maybe there was something to it?

I've been putting off getting a proper sports bra for awhile, and I'm a double D.

I guess I should finally take the plunge and get something proper

As a side note, I bet the guys tracking the movement of the boobs loved this research, haha.

TheSame7-- sad little A cups? i WISH! ive got "sad-little-10year old-daughters-training-bra!!""
im actually not joking ! Definitely comes in handy for running though, however not so much when im trying to "work-it!"

Oh, man. I totally just sent that to my husband so he could understand why I complain SO much that I absolutely CANNOT find a sports bra. It doesn't EXIST!

I'm a 42d now and even when I was a 36C, I still could not find a sports bra! It's impossible. I'm going to have to find something if I want to start jogging though. Thanks for the article!

Interesting! I'm a 36DD and for some reason I can't find a sports bra that gives support without mushing the breast together uncomfortably. I've tried tons of brands. What I've been doing lately is wearing a regular bra and a tight sports bra over that. So far it's working.

I have a proper sports bra (a Freya that I think was about $50 or so) and I still have to wear a snug, over-the-head Champion sports bra over that. This combination is the only thing that will allow me to comfortably go running. I'm a 34G, so that's some pretty powerful bra action going on to keep these girls from bouncing around.

If someone could make a good sports bra that would stop the bouncing around, they'd be a millionaire.

Interesting.

For those larger breasted girls, I highly recommend the Moving Comfort Fiona sportsbra. It's not cheap, but it's not in the SUPER expensive sports bra range. It's very supportive. My favorite part is that it's adjustable. So, you can loosen or tighten it each day--and even if you lose some weight in your chest! The tightening feature helps me feel secure when working out at very high impact.

I recently was experiencing serious pain during and after runs. I googled and found some info similar to this, and when I learned "the girls" were doing figure eights when I ran, I understood why they were hurting! I invested in two somewhat pricey sports bras - Champion 360 and Shock Absorber Max - and it has made a world of difference. Very comfortable, very supportive, and (hooray) no more uni-boob! (I wear a 36FF in "regular" bras....I'm definitely in the "big girls" category.)

MK, when I said "said little A cups" I was being generous -- I wear A-cup push-up bras and I still can't fill them (the cups in the push-ups are about half the size of a regular A-cup). I think I was a true A-cup before I nursed my three kids for more than a year each -- now I am also training bra size. I really only read this article in case my boobs suddenly get bigger one day -- but not thrilled with the possible complications of that procedure...

StephanieM, I was totally thinking the same thing -- tough day at work for those guys!

I looked--too bad, it doesn't come in nearly big enough cup size. Booooo! DD just won't cut it. But it does look pretty firm!
