The purpose of this study was to examine head movement control during running and sidestepping tasks. Fourteen collegiate male athletes performed running and sidestepping tasks. Sagittal and transverse head and trunk angles, vertical trunk displacement and head-trunk coordination were assessed during the flight and stance phases. The sidestepping task resulted in greater transverse and sagittal plane head and trunk range of motion. During stance, transverse plane head-trunk coordination was more in-phase, with reduced vertical trunk-sagittal head anti-phase coordination during sidestepping tasks. During sidestepping tasks, visual field reorientation required greater contributions from the head in the transverse plane, but with reduced sagittal plane compensation, reduced perceptual awareness may be observed, with negative implications on sport performance and injury risk.
