The purpose of the study was to analyze the influence of footwears and breast supports on the spine movements during running. Seventeen women performed a treadmill run using different combinations of footwear (barefoot, minimalist and traditional) and breast support (bare breast, everyday bra and sports bra). Spine movements were registered using optoelectronic cameras that recorded reflective markers fixed from the cervical to the sacral regions. From the 3D coordinates of the markers, the geometric curvatures of the spine were calculated in the sagittal plane at each instant of time in the gait cycle, as well as the neutral curve (mean posture of the spine). Results showed that the sports bra and footwear caused greater curvatures in the thoracic and lumbar regions, respectively, suggesting that women change their posture depending on the sportswear used.
