Caffeine improves saccade velocity after exercise fatigue

SEATTLE β€” Fatigue-induced impairments in saccade velocity after prolonged strenuous exercise can be reversed by caffeine, according to a poster presented here.β€œIt has been proven in primates that fatigue affects saccadic eye movement,” poster presenter Charlotte J. Connell told Ocular Surgery News at the Association for Research in Vision and Ophthalmology meeting. With that premise, the researchers randomized 10 cyclists to receive either placebo or caffeine during a 180-minute cycling protocol. Saccadic eye movements and global motion perception were assessed before and after the protocol.
