Research reinforces Rheon bra benefit claims
New research from a team led by biomechanics professor Dr Joanna Wakefield-Scurr has found that using composite thermoplastic elastomer Rheon can help brands address a key barrier for women in sport.
London-based Rheon Labs brought Rheon to market in 2023. It describes the product as “a reactive super-polymer” that can help athletes improve their performance by giving them greater “energy control”.
Professor Wakefield-Scurr’s new research, commissioned by Rheon Labs, suggests that use of the Rheon in sports bras can, without increasing compression, reduce breast movement by an additional 15% during medium-intensity physical activity. She has pointed out that reducing movement reduces pain and discomfort.
Bra developers typically rely on compression, she explained, flattening the breasts to minimise movement. But compression can feel restrictive or even painful, especially during long workouts. She said excessive compression can also impair oxygen consumption, reduce endurance, and lower running speeds.
She concluded: “We know that inadequate breast support can have a real impact on comfort and performance. Our findings demonstrate how small but significant innovations can make a meaningful difference to women’s experiences during physical activity.”
From the company’s point of view, chief science officer, Dr Sarah Karmel, said Rheon Labs had the aim of creating technology “that works with the body rather than against it”. She said the composite thermoplastic elastomer “adapts to women’s movements, offering support exactly where it’s needed”.
