Why Did Adidas Re-Engineer Their Entire Sports Bra Portfolio

A sports bra is the single most important piece of workout apparel for those with breasts, but 90% of women aren’t wearing the right size.

That’s why adidas have now re-engineered their entire portfolio with 43 new styles, available in 72 sizes, catering to more bodies and workouts than ever before.

In sport, everybody should feel free and inspired by what their bodies can achieve. But women’s needs are historically underserved when it comes to sportswear designed to support the female form.

In fact, just 17 years ago when Professor Joanna Wakefield-Scurr set up a pioneering research group in breast health at the University of Portsmouth, there were only 6 scientific studies on the biomechanics and support requirements of the breast, while there were 1000’s of studies on sports shoes.

Together with Professor Wakefield-Scurr and the University of Portsmouth, adidas have set out to shine a light on the importance of proper breast support, and the life-changing benefits it can have on sports participation and performance.

If breasts aren’t properly supported during running, they can move up to 19cm and could experience the same G force as an F1 driver.

This is because there are no muscles in the breast. Instead, it is a lump of tissue that sits in front of the pec muscles, but it is not attached to them.

The only natural support the breast has is the skin and Cooper’s ligaments, which are very thin, stretchy structures that exist to protect the milk-producing parts of the breast, but not to lift and hold it.

Unknown to many, athletes may require the same amount of breast support during power walking as they do during sprinting, and a lack of support has the potential to cause irreversible damage. Breast movement in sport continues to be an area that is overlooked,” explains Professor Joanna Wakefield-Scurr.

So the fact is, we don’t have enough natural support in the breast to hold it firmly in place.

When we move, the breast moves, which can cause breast pain, permanent breast tissue damage, and impact sports performance.

Women’s bodies and breasts come in many sizes, and there are endless ways in which they move during exercise.

There really is no ‘one size fits all’ when it comes to bras, and due to a lack of choice, it’s not surprising that 90% of women aren’t wearing the right sports bra size.

The adidas research has shown that wearing a well-fitting sports bra reduces movement-related breast pain.

If we stop the breasts from moving, we reduce the risk of damaging the skin and the Cooper’s ligaments.

The right sports bra also improves function and impacts stride length. For example, when you run a marathon, your breasts run an extra four miles on their own if not properly supported.

“There is a sizeable data gap when it comes to sports bra development, so we worked with experts in breast health and biomechanics, University of Portsmouth, to challenge ourselves and drive forward our innovation to better meet the needs of our female athletic community,” said Amy Charlton, Senior Director Product at adidas.

This year adidas are making their biggest ever commitment to women and a big part of how we do that is by innovating products to better serve our athletic community.

Sports bras are a foundational piece of kit, but research into the category uncovered vast dissatisfaction from women who weren’t being properly supported.

That’s why – after comprehensive research and development – adidas have created 43 new styles across 18 product franchises, to give them more choice and help them find the sports bra that’s right for them.

This is adidas’s most extensive and size-inclusive sports bra collection to date, created to help more women experience sport without restraint.
