All parts of our body bounce as we walk around and do everyday chores. But, when it comes to doing impact aerobic workout, we really want to contain the bounce of our breasts for comfort and well as to keep them from becoming pendulous and sagging. So, do we need to bind our breasts and prevent any movement, or can we let some breast movement occur?

I put this question to Dr. Joanna Scurr. Dr. Scurr is the lone researcher of breast bounce. Here were some of her comments.

First, we need to understand that breasts are kept in place by the Coopers Ligament – not muscles. Once the ligament becomes stretched, your breast sag, and there is no way to reverse the sagging. A sports bra, or most bras for that matter, support one’s breasts to reduce breast movement. Even testing of breast movement on an everyday bra, says Scurr, showed that it reduced breast movement by 49% compared to not wearing any bra at all.

Dr. Scurr’s research also found that breasts just don’t move up and down, but from side to side and in and out. All this movement, if not supported will contribute to sagging breasts. So, though it would be nice to have a sports bra that provides no breast movement, the truth is, as long as you have a sports bra that reduces your breast bounce enough so that the movement is less than your normal breast hang, you are protected and no further sag damage can occur.

At HerRoom, we offer the Bounce Test videos on all our high impact sports bras. Some clearly don’t provide enough support, but many also show some breast movement. What been learned here is that some movement is fine, but just make sure the movement is less in the 3 directions than your breasts normally move. This way, you won’t be stretching any of the breast’s ligaments or tendons during impact workouts.
