Predictors of 3-D Breast Kinematics during Bare-Breasted Running

A six-person research team has just released its findings about the predictors of three-dimensional breast kinematics during bare-breasted running. Details are in their singular study:

Predictors of Three-Dimensional Breast Kinematics during Bare-Breasted Running“, Louise Ellen Wood, Jennifer White, Alexandra Milligan, Bessie Ayres, Wendy Hedger, and Joanna Scurr [pictured here], Medicine and Science in Sports and Exercise, vol. 44, no. 7, July 7, 2012, pp. 1351-7.The authors, at University of Gloucester and the University of Portsmouth, UK, report:

PURPOSE: This study aimed to analyze differences in breast kinematics between breast cup sizes during running and the ability of breast and body size measurements to explain these differences.

METHODS: Forty-eight women (A to G cup; mean ± SD: age = 26.0 ± 6.0 yr, stature = 1.667 ± 0.064 m, mass = 62.78 ± 8.24 kg) with chest sizes of 32 to 38 inches participated. Chest and breast girths, a restricted anthropometric profile, suprasternal notch to nipple distances, and body mass index were measured, and breast mass was estimated. Multiplanar relative breast displacement, velocity, and acceleration during treadmill running were then recorded. Differences in breast kinematics were compared between cup sizes before and after allometric/polynomial scaling using significant breast and body size measures.

RESULTS: All kinematic variables significantly increased with breast cup size… Scaling models found that breast mass was the only anthropometric measure to consistently explain differences in breast kinematics between cup sizes.

CONCLUSIONS: Bare-breasted kinematics significantly increased with cup size during running.
