The Impact of High-Support Bras on Spinal Health

Recent research conducted by the University of Portsmouth raises questions about the effects of high-support bras, particularly sports bras, on spinal health. While these bras are designed to minimize breast movement during physical activities, they might inadvertently contribute to spinal discomfort.

The study, published in the European Journal of Sport Science, indicates that while sports bras play a crucial role in alleviating breast pain during exercise, those that achieve maximum bounce reduction could exert additional stress on the spine. This research utilized advanced techniques such as motion capture and force platforms to examine how breast movement impacts spinal forces.

Researchers developed a specialized musculoskeletal model tailored to women to investigate the relationship between breast support and spinal dynamics while running. Findings suggested that while reducing breast bounce is beneficial for comfort, excessive restriction may lead to increased spinal loading, potentially heightening the risk of lower back pain.

Dr. Chris Mills, leading the study, emphasized the need for balance in bra design. He noted that while comfort is paramount during exercise, overly supportive bras could strain spinal muscles, leading to discomfort or pain. The findings advocate for manufacturers to consider the musculoskeletal implications of their designs.

Professor Wakefield-Scurr, a prominent figure in breast health research, echoed these concerns, suggesting that the pursuit of maximum bounce reduction might unintentionally jeopardize spinal health during activities such as running. As the sports bra industry continues to evolve, there is an urgent call for innovation that harmonizes comfort, support, and overall health.

The study builds on two decades of ongoing research from the university's Research Group in Breast Health, which has tested over 700 sports bras on more than 8,000 women. The creation of a female-specific musculoskeletal model allows for a nuanced understanding of how variations in breast motion can affect spinal dynamics. This model also holds promise for developing personalized rehabilitation strategies, particularly for women undergoing breast surgery.

Moving forward, the objective is to identify the optimal level of breast support that mitigates exercise-induced discomfort while preventing adverse effects on spinal health. By gaining insights into individual muscular responses, researchers aim to create bras that not only enhance performance but also minimize injury risks. The study serves as a reminder of the complex interplay between garment design and physical health, urging industry leaders to prioritize holistic well-being in their products.
