Bounce the bosom of building better bras
11:49 AEST Sun May 22 2005
It might be hard to believe, but there’s some serious science being used to study the way women’s breasts bounce.
Biomechanics experts at the Australian Institute of Sport (AIS) in Canberra have been helping manufacturer Berlei improve its sports bras for a decade.
The latest round of tests is being done this weekend at the institute, which has emerged as a world leader in the research.
The effectiveness of the bras is measured through a series of tests on a treadmill – walking, jogging and running.
Breast movement is recorded through the Vicon system, a quarter of a million dollar hardware and software package that uses high-speed cameras to pick up signals from markers placed on the clavicle and on each breast of the subject.
The data is then analysed by computer, producing a three-dimensional representation on screen of breast displacement and movement, as well as extremely accurate measurements.
The differences in support provided by different bras often comes down to a just a few millimetres of movement.
“We’re pretty confident when we come up with a measurement that this is a true measurement,” AIS head of biomechanics Bruce Mason told AAP.
“Even though there’s only one or two millimetres’ difference between the two, we can say this bra is providing better support than that bra.”
Dr Mason said the research was important for women’s health.
“We believe there is a connection between how much and how much pain occurs, and how much damage is occurring, and one of the things girls are very concerned about is – is this affecting me in the future?
“When you consider that half the population are female, and this very thing affects how they enjoy their activity, it is something that is very important.”
Berlei product manager Louise Woods said the team would be testing more than a dozen bras covering several different models, including maternity bras.
The research, she said, was “incredibly valuable”.
“It all feeds into our design process”.
Ms Woods also said there was plenty of support for the research from women with large breasts who had trouble getting comfort out of a bra.
“The bigger ladies, they would do (the testing) for nothing,” she said.
“There’s a lady we’ve got coming tomorrow who said, `Oh my God, am I getting paid for this?’”
Dr Mason said the AIS had had several papers published from its bra studies and had become a world leader in the research.
“I don’t know of any group that’s further ahead than us on this,” he said.
