The Impact of Ill-Fitting Sports Bras on Breathing and Energy Levels

A new study funded by Lululemon and conducted by researchers at the University of British Columbia suggests that wearing a too-tight sports bra can affect breathing and impede running performance. The study tracked the breathing and lung function of elite runners and found that a too-tight bra caused them to take more shallow breaths and consume more oxygen, leading to decreased running economy. Experts recommend wearing a sports bra that offers adequate support without being too tight around the rib cage, emphasizing the importance of proper fit for optimal performance and comfort during exercise.
