Healthy (non-injured) and concussed college-aged participants will complete two testing
sessions that include (1) clinical symptom, balance, and cognitive evaluations and (2) a
progressive exercise session to establish symptom exacerbation or maximal exercise capacity.
Individuals randomized to the control group will receive no intervention between sessions,
while individuals randomized to the intervention group will complete 30 minutes of stationary
bike exercise at least 3 days/week.
