Breast support performance during short and prolonged running

Recommendations for breast support, dynamic breast pain assessment, and implications on sports performance have been made within breast biomechanics research; however, these have been based upon short exercise protocols (2 to 5 minutes). The aim of this study was to determine the effect of breast support on multiplanar breast displacement and bra performance during short and prolonged running. Significant increases in the mulitplanar breast displacement and a significant decline in the low and high breast support performance were reported from the start to the end of the five kilometre run. Based upon this study, breast biomechanics research and sports bra manufacturers should consider the duration of exercise and product validation protocols, to ensure accurate representation of product capabilities.
