“…The fact that the animals in this study voluntarily resumed activity soon after TBI, and showed better performance on outcome measures, suggests that it was not harmful. Interestingly, a recent review of clinical studies of exercise and TBI identified that levels of activity were lower than that required for optimum health and were influenced by factors such as self‐efficacy to exercise and motivation (Hamilton et al ., ). It was further suggested by the Hamilton et al .…”

“…It was further suggested by the Hamilton et al . () paper that identifying barriers to exercise will be important to improving long‐term outcomes after TBI. In comparison while our study showed a benefit of early exercise, others have shown bimodal time‐dependent effects of exercise that are exacerbated by stress, and are linked to autonomic regulation and HPS axis function (Griesbach et al ., , ).…”

Despite the most common form of brain injury, there has been little progress in the prognosis and treatment of concussion/mild traumatic brain injury (mTBI). Current 'return-to-play' guidelines are conservative, deterring the initiation of physical and social activity until patients are asymptomatic; but the effects of post-injury exercise have not been adequately investigated. Therefore, this study examined the effects of voluntary exercise on concussion recovery. Using a translational rodent model of concussion, we examined the influence of exercise on injury-associated behaviours that comprise post-concussive syndrome (PCS) and gene expression changes (bdnf, dnmt1, Igf-1, pgc1-a, Tert) in prefrontal cortex and hippocampus. In addition, as we have previously demonstrated telomere length (TL) to be a reliable predictor of mTBI prognosis, TL was also examined. The results suggest that exercise initiated within 1-3 days post-concussion significantly improved motor and cognitive functioning, but had limited efficacy treating emotional impairments. What is more, when deprived of social interaction and exercise, a combination similar to clinical recommendations for rest until symptom resolution, animals did not recover and exhibited impairments similar to typical mTBI animals. Exercise aided in restoration of mTBI-induced modifications to gene expression in both brain regions. An inverse relationship between the exercise return interval and TL was identified, indicating greater recovery with acute exercise reinstatement. Although additional strategies may need to be employed for emotional functioning, these findings support re-evaluation of 'returnto-play' guidelines, suggesting that exercise is valuable for the treatment of concussion.

“…Both environmental factors and individual factors have been reported as barriers to physical activity for individuals following moderate to severe TBI [22,23]. Environmental barriers include lack of transportation and lack of accessible facilities to complete physical activity, whereas individual barriers include decreased endurance, self-consciousness in fitness centers, and lack of time [22].…”

Physical activity and exercise are important adjuncts to medical treatment for overall health in individuals with traumatic brain injury (TBI); however, many individuals do not partake in the recommended weekly exercise. The objective of this study was to investigate the barriers to exercise after TBI and determine whether these barriers varied by age. The sample was 172 adults with moderate to severe TBI who completed Barriers to Physical Exercise and Disability (B-PED) survey. Lack of interest, motivation, and energy as well as cost, lack of counseling on exercise by a physician, not having home equipment, and being too lazy were reported as barriers to exercise by all age groups. Those aged 35 to 54-years-old were more likely to report that cost, lack of transportation, having health concerns, not knowing where to exercise, and fear of leaving the home as barriers to exercise than those aged 18 to 34-years-old or 55-years-old and older. Overall, adults with TBI report multiple barriers to exercise, and these barriers vary by age.
