Brief Summary:
Aerobic exercise holds a multitude of health benefits. Studies in mice have shown that aerobic exercise improves memory, and increases the volume of the hippocampus, the brain's primary memory center. Only two studies have been conducted in humans, one in healthy elders, and the other in a schizophrenia population. So far, there has never been an aerobic exercise trial in traumatic brain injury (TBI) to look at hippocampal volume and memory as outcomes of interest. The proposed project is a randomized controlled trial of aerobic exercise in persons with TBI. We will conduct a 12-week (36 sessions) program of aerobic exercise (stationary cycling), versus a control condition of non-aerobic exercise (stretching), in memory-impaired TBI patients to a) increase hippocampal volume and b) improve memory. Importantly, we also expect benefits of aerobic exercise on the level of brain function. Specifically, we will look at 'functional connectivity,' which refers to how efficiently remote regions of the brain 'talk' to each other. TBI is an ideal population to benefit from aerobic exercise, given the young age at which many individuals sustain TBI, which allows for benefits of aerobic exercise to be maximally realized in a population with sufficient neurofunctional reserve. The expected benefits of aerobic exercise (increased hippocampal volume, improved memory) from this intervention stand to have a meaningful impact on people with TBI, including improved health, productivity, independence, and quality of life. And, unlike current treatments for memory impairment (e.g., pharmacological agents, cognitive rehabilitation), aerobic exercise is a cost-effective, all natural, readily-available treatment for memory problems.

Arm Intervention/treatment
Experimental: Aerobic exercise
30 minutes x 3 times/week x 12 weeks of stationery cycling
Behavioral: Aerobic exercise
Placebo Comparator: Non-aerobic exercise
30 minutes x 3 times/week x 12 weeks of gentle non-aerobic stretching
Behavioral: Placebo control
Non-aerobic stretching sessions will be conducted 3x/week for 30 minutes over 12 weeks.

Primary Outcome Measures :
  1. Hippocampal volume [ Time Frame: 1 week post intervention ]
    Volumetric software will be used to measure hippocampus at baseline and follow-up (within 1 week of completion of 12-week intervention).
