Cerebrovascular reactivity (CVR) can provide a marker of vascular injury. The effects of repetitive head impact exposure (RHIE) during contact sports remains to be fully elucidated. We investigated the effect of sport, time, and their interaction on CVR in contact sport (CS) and non-contact sport (NCS) middle school and high school athletes. There was a significant effect of time and a significant interaction effect between contact group and time on CVR with CVR decreasing pre to post season in the NCS group but remaining unchanged in the CS group.
