Ergonomic design system of the volume fitting stretch for design of the sport bra style and its simulation remains a major challenge, even if applications are numerous, from rapid mathematical for e-commerce to a stable arithmetical for stretch comfort design cloth of sport bra surfaces. This study compared seven sports bras on quantitative and subjective measures of arithmetical comfort as well as ergonomic stitchless items for small, medium, and large breasted women during exercise. Representing different cup magnitudes were filmed while jogging on a treadmill at 6 mph in each bra style and in the nude condition. The average stitchless model of vertical displacement of the breast relative to the body was described mathematically for each condition. A two-way repeated measures of mathematical ergonomic stitchless model of volume fitting stretch that is aimed at designing a sport bra and subsequent pair wise comparisons indicated significant differences by bra style in subjective mean comfort scores. Correlation coefficients between vertical displacement values, subjective measures of support, and subjective measures of comfort indicated that bras, which effectively controlled breast displacement, tended to score lower on comfort design. Obtained results might help produce reports from the external level that arranged for forecasting suitable fashion of a sport bra design.
