The purpose of this study was to assess the aerobic exercise-induced fatigue effects upon several aspects of the visual system. Forty subjects participated in this study. The subjects were tested pre- and post-fatigue. Fatigue was instituted by having the subject pedal a stationary exercise bicycle at a pre-determined target heart rate for a period of 15 minutes. The tests performed were; dissociated lateral phoria, static visual acuity, lateral fixation disparity, stereoacuity, contrast sensitivity, reaction/response time, and a perceptual speed task. Statistically significant results (p<0.05) were demonstrated in lateral fixation disparity and the perceptual speed task. These results show that physical fatigue does effect certain aspects of the visual system related to sports performance.
