This research aims to develop an intervention that combines mTBI-specific motor and cognitive challenges into a progressive and challenging rehabilitation program. We plan to develop and refine a combined motor and cognitive intervention using healthy athletic young adults (n=12) and people with a positive history of non-resolving mTBI (n=12). We will conduct limited feasibility testing by conducting 6 week training sessions with each subject group. We also plan to identify best measures for determining readiness for duty or full function by incorporating and testing 3 dual-task assessment measures using state-of-the-art wearable sensors to quantify movement.

Inclusion criteria-healthy control:

• Adults aged 18-34 years of age.
• Strong history of athletic participation including high school and collegiate varsity and/or club sports
• Current sport or recreational sport participation at least 3 days per week
• Willingness to participate in 3 times a week 60 minute exercise program conducted at Courage Kenny Research Center (CKRC).

Exclusion Criteria-healthy control:

• History of concussion.
• History of orthopedic or neurologic diagnosis (stroke, multiple sclerosis, Parkinson's Disease, etc.) interfering with subject's ability to exercise
• Unwilling to exercise.
• At risk for cardiopulmonary disease as defined by the American College of Sports Medicine.
• Active medical contraindications by self-report after explanation of dual-task exercise program.
• Active chemical dependency or major psychiatric disorders (ie., schizophrenia, major psychosis) by self-report.

Inclusion criteria-subjects with mTBI residual symptoms:
