This study aims to objectively evaluate the trunk posture of sweep rowers (bow-side rowers/stroke-side rowers) and compare the results with scull rowers and non-rowing controls. Sixty-four healthy individuals divided into four groups were assessed using a DIERS formetric III 4D device that is based on a method of moiré topography. There were seven parameters observed in an assessment of standing posture, and eight parameters were studied for an evaluation of posture during the gait cycle. In comparison with non-rowing controls and scull rowers, stroke-side rowers showed significantly greater rotational deviation of the trunk at the L3 vertebra level and a greater magnitude of scoliosis angle during walking throughout the single support phase on the left leg (p < 0.05). Stroke-side rowers also demonstrated greater magnitude of scoliosis angle than non-rowing controls in double support phase in the transition from the left to the right leg (p < 0.05). Moreover, as opposed to non-rowing controls, stroke-side rowers and scull rowers showed significantly greater values of coronal imbalance (p < 0.05). Bow-side rowers differed from non-rowing controls and scull rowers in a significantly greater magnitude of scoliosis angle throughout the single support phase on the left leg (p < 0.05).
