The purpose of this investigation was to identify the effects of soccer match-specific physical exertion on deployment of movement strategies to control the centre of mass (CoM) in the medio-lateral direction during unanticipated side cutting. Twenty-one healthy male recreational soccer players completed a 90-minute over-ground soccer match-simulation. Integrated to the match-simulation were 45° unanticipated side cutting tasks using a 4-5 m·s-1 approach speed. Performance outcomes, peak knee abduction moments (peak KAM), and whole-body dynamic stability variables were calculated for the side cutting tasks. A reduction in the capacity to generate medio-lateral forces from sagittal methods may explain the drop in average medial CoM acceleration and change of direction angle. An ankle movement strategy, represented by a lateral movement of the centre of pressure (CoP) position, appears to have been deployed to mitigate any additional drop in side-cutting performance. A single match-simulation may be insufficient to increase injury risk markers unless the individuals are already showing signs of a reduced ability to mitigate unnecessary movement deviations.
