A Latin Square Experimental Design was used to compare a prototype sports bra previously developed for large-busted women, with two other sports bras through a controlled laboratory wear study. Vertical breast displacement data were gathered by videotaping the first three running strides of six large busted active females recruited from local fitness centers. Multiple regression results found that the garment treatment significantly related to the breast displacement experienced by subjects during each test session [F (2,213) = 16.393; p< .0001]. Approximately 13% of the variability in breast displacement was predicted by garment, indicated by the Squared Multiple Correlation Coefficient. ANOVA results found significant subject, garment, and subject-by-garment effects. Subjects wearing garments A and B had a lower level of vertical breast displacement of .031” as compared to subjects wearing garment C with .045” of displacement.
