Summary

Professor Joanna Wakefield-Scurr leads an 18-person team at the University of Portsmouth's Research Group in Breast Health, focusing on designing improved bras. Her work, initiated two decades ago due to personal breast pain, addresses the lack of historical research on unsupported anatomical structures. The team discovered that breasts move in a three-dimensional pattern during running, bouncing approximately 10,000 times in an hour of slow jogging. Their findings indicate that effective high-impact sports bras feature underwires, padded cups, adjustable underbands and shoulder straps, and hook-and-eye closures, reducing breast movement by up to 74%. Poorly fitting bras cause pain and are a significant barrier to exercise for women, while good sports bras increase willingness to run. The lab is exploring new materials that adapt to movement, collaborating with manufacturers to develop solutions, as demand for better bra design outstrips current research capacity.

Key takeaway

For product managers and entrepreneurs in activewear, understanding the biomechanics of breast movement is critical for innovation. Your designs should prioritize features like underwires, padded cups, and adjustable components to reduce 3D movement and prevent "breast slap." Focusing on comfort and effective support can significantly lower barriers to exercise for women, opening new market opportunities and improving product adoption.

Key insights

Effective bra design requires understanding complex 3D breast movement and its impact on comfort and exercise participation.

Principles

• Breast movement is 3D during exercise.
• Poor bra fit deters women from exercise.
• Supportive bras reduce movement by up to 74%.

In practice

• High-impact bras need underwires, padded cups.
• Adjustable underbands and straps are crucial.
• Hook-and-eye closures enhance support.

Topics

• Breast Biomechanics
• Sports Bra Design
• Women's Exercise Barriers
• Biomechanical Research
• Textile Innovation
