Persistent contact sport participation exposes athletes to repetitive head impacts, eliciting lingering motor performance alterations that could disrupt visual perception. We sought to compare head and trunk displacement, segmental coordination, and dynamic visual acuity between contact (ice hockey) and noncontact (baseball) athletes. Thirteen ice hockey and 11 baseball athletes walked at preferred and fast speeds during both a baseline and an imposed dynamic visual acuity (DVA) task. With increased visual task constraints and walking speeds, greater vertical head (preferred walking with visual task: 4.29 ± 0.48 vs 3.69 ± 0.71 cm,
