Executive dysfunction represents a persistent concussion deficit; however, it is largely unclear whether the deficit persists in an athlete after they have been deemed safe to return to play. In the present work, athletes with a sport-related concussion, and their age- and sex-matched controls, completed prosaccades and executive-related antisaccades: (1) 2-6 days post-concussion (i.e., initial assessment), and (2) 14-20 days after initial assessment and only when an athlete was medically cleared for safe return to play (i.e., follow-up assessment). Initial assessment antisaccades for the concussed group produced longer reaction times (RT) and more directional errors than the control group. The …

A single-bout of moderate-to-vigorous intensity exercise increases activity within frontoparietal networks, producing a temporary ‘boost’ to executive-related cognitive control – an effect that is thought to be selective to exercise durations greater than 20 minutes. It is possible that previous tasks evaluating executive control did not provide the requisite resolution to detect executive changes associated with shorter exercise durations. To that end, I had participants perform a 10-minute bout of moderate-to-vigorous intensity aerobic exercise, examining pre- and post-exercise executive control via the antisaccade task. Extensive literature has shown that antisaccades are mediated via frontoparietal networks, modulated following exercise training. Results …
