Key Points

  • The aim is to analyze how different breast types respond to various running intensities using finite element simulations.
  • Finite element method simulations conducted on nine breast types.
  • Evaluated effects of breast volume and running speed on displacement and acceleration.
  • Assessed nipple spatial configuration's impact on lateral dynamics.
  • Found significant increases in breast displacement and acceleration with larger breast volume and higher running speed (p < 0.001).
  • Identified breast volume and speed as key predictors of motion in Y and Z directions.
  • Observed that middle-type breasts showed greater stability during lateral movement.

Abstract

This study investigates the dynamic breast response of nine representative breast types by finite element method, focusing on the effects of breast volume, running speed, and nipple spatial configuration. The simulation revealed that greater breast volume and higher speed significantly increased displacement and acceleration (p Y- and Z-directions, while nipple position type modulated lateral dynamics. Notably, middle-type breasts exhibited greater lateral stability. These findings offer biomechanical insights into breast movement, and provide basis for the design of sports bras tailored to different breast morphologies.
