Research: Proper Sports Bras Improve Running Economy

Forty-four percent of elite female athletes experience exercise-induced breast pain, according to research involving 540 elite female athletes.

That discomfort directly impacts athletic output. Nearly one-third of those athletes reported that the pain negatively affected their sporting performance during physical activity.

Beyond comfort, proper breast support influences athletic efficiency. Research involving female recreational runners found that individuals wearing higher-support sports bras used less oxygen and demonstrated improved running economy compared to runners wearing lower-support bras.

To ensure proper performance and reduce discomfort, athletes are advised to choose the correct level of support for their activities. High-impact sports such as soccer, running, and basketball generally require high-support sports bras, though individual needs and comfort vary.

When checking fit, the band must sit level and snug around the ribcage without riding up or restricting breathing. The cups should comfortably contain all breast tissue without gapping, spilling, or wrinkling, while straps must feel secure without digging into the shoulders.

Athletes should test the fit with movement by jogging, jumping, twisting, and changing direction to guarantee adequate support without restricted motion. Moisture-wicking and breathable fabrics help manage sweat and minimize irritation and chafing.

Because elastic and fabric lose support over time, frequent users should reassess their bra fit every 6 to 12 months. Replacements are necessary when the band becomes loose, straps lose elasticity, or the garment no longer offers adequate support.

Growing athletes also experience changing bodies over time. A sports bra that provided a comfortable fit last season may fail to deliver identical support later, requiring periodic reassessments during periods of physical development.
