BACKGROUND: Exercise training is associated with elevations in mood in patients
with various chronic illnesses and disabilities. However, little is known
regarding the effect of exercise training on short and long-term mood changes in
those with traumatic brain injury (TBI).
OBJECTIVE: The purpose of this study was to examine the time course of mood
alterations in response to a vigorous, 12-week aerobic exercise training regimen
in ambulatory individuals with chronic TBI (>6 months postinjury).
METHODS: Short and long-term mood changes were measured using the Profile of Mood
States-Short Form, before and after specific aerobic exercise bouts performed
during the 12-week training regimen.
RESULTS: Ten subjects with nonpenetrating TBI (6.6 ± 6.8 years after injury)
completed the training regimen. A significant improvement in overall mood was
observed following 12 weeks of aerobic exercise training (P = .04), with moderate
to large effect sizes observed for short-term mood improvements following
individual bouts of exercise.
CONCLUSIONS: Specific improvements in long-term mood state and short-term mood
responses following individual exercise sessions were observed in these
individuals with TBI. The largest improvement in overall mood was observed at 12
weeks of exercise training, with improvements emerging as early as 4 weeks into
the training regimen.
