Subjects who are collegiate level athletes who do not have a concussion and are currently playing a contact-collision sport.
Subjects who have recently suffered a sports-related concussion and are currently a collegiate athlete playing a contact-collision sport.
- Cerebral blood flow regulation [ Time Frame: Change in Control, 3 days post concussion, 21 days post concussion, and 3 months post concussion ]Subject's cerebral blood flow regulation (cm/sec) at rest, during a cognitive test, and during a breathing test will be measured.
- Blood Biomarkers [ Time Frame: Control, 3 days post concussion, 21 days post concussion, 3 months post concussion ]Subjects will have their blood drawn so investigators can look at biomarkers in their blood. The biomarkers will be Tau, a-Spectrin N-Terminal Fragment, Neuron-specific enolase, Ubiquitin C-Terminal hydrolase L1, S100B, and Glial fibrillary acidic protein.
- Memory Function Test [ Time Frame: Control, 3 days post concussion, 21 days post concussion, 3 months post concussion ]Subjects will be given paper tests to test their memory function.
- Balance Test [ Time Frame: Control, 3 days post concussion, 21 days post concussion, 3 months post concussion ]Subjects balance will be measured using a force plate.
- Orthostatic Tolerance Test [ Time Frame: Control, 3 days post concussion, 21 days post concussion, 3 months post concussion ]Subjects physiological measurements will be measured as the move from a seated position to a standing position.
- Cerebral Vasoreactivity [ Time Frame: Control, 3 days post concussion, 21 days post concussion, 3 months post concussion ]Subjects will breathe normal air, a 8% carbon dioxide gas mixture, and hyperventilate.
