- Phase: None
- Number of Arms: 2.0

Eligibility Criteria:
Inclusion Criteria:~* Ages 14-35~* Prior to injury, participant fulfilled ACSM's guidelines for regular aerobic activity (30 minutes of moderate-intensity exercise 5 days per week or 20 minutes of vigorous exercise 3 days per week) prior to injury.~* Diagnosed with a sport related concussion within 14 days of injury in the window of 3-30 days prior to completing the first study visit, and also being a single episode.~* Participants referred to exertion therapy after a trained clinician from University of Pittsburgh Medical Center (UPMC) Sports Medicine Concussion Program has interpreted neurocognitive, vestibular, and clinical interview outcomes~Exclusion Criteria:~* History of brain surgery or traumatic brain injury(based on Glasgow Coma Scale of \<13)~* History of neurological disorder (seizure disorder, epilepsy, brain tumors or malformations)~* Current history of pre-existing vestibular disorder \[benign paroxysmal positional vertigo (BPPV), labyrinthitis or vestibular neuritis\]~* Previous diagnosis of ocular motor condition (Ocular motor apraxia)Currently taking anticoagulant, beta-blockers, and anticonvulsant prescription medication~* Diagnosed with a cardiac, peripheral, or cerebrovascular disease (type 1 or 2 diabetes, or renal disease.~* Experienced chest pain or shortness of breath while at rest or with mild exertion.~* Lose balance because of dizziness or have lost consciousness (aside from concussion) from exertion~* Diagnosed with or taking medication for a chronic medical condition~* Currently have a mental or physical impairment exacerbated by physical activity, leading to the inability to complete 30 minutes of moderate to vigorous exercise~* Been told by a doctor to only conduct physical activity under medical supervision.

Study Arms:
- Aerobic (treadmill) Exercise (Type: ACTIVE_COMPARATOR): Participants will wear a heart rate monitor and complete the Buffalo Concussion Treadmill Test
- Dynamic Exercise (Type: EXPERIMENTAL): Participants will wear a heart rate monitor and complete a dynamic exertion assessment that incorporates directional changes that incrementally increases in exercise intensity

Based on this trial design, predict the completion outcome and termination type (if applicable).
