Breast biomechanics
Scurr recruited 70 women, including students and faculty from the University of Portsmouth, with bra sizes ranging from A-cup to extra-large (DD, E, FF, G, H, HH, J and JJ were included).
Each woman walked, jogged and ran while wearing different bra types. During the exercise, Scurr took biomechanical measurements, including the amount of breast movement in three directions: up-and-down, side-to-side and in-and-out.
During walking exercise, the women’s breasts moved relatively the same amount in all directions. But when participants sped up to a jog or run, their breasts moved proportionally more in some directions than others: More than 50 percent of the total movement was in the up-down direction, 22 percent side-to-side and 27 percent in-and-out.
The overall pattern of the movement resembled a figure-8.
Typically, bras are designed to minimize up-and-down motion and not the other two dimensions of breast movement found in Scurr’s study.
