aerobics can lift depression


(Reuters Health) Apr 05 - A simple program of regular aerobic
exercise can substantially improve depression scores in patients with
moderate to severe major depression, despite prior failures with
pharmacologic therapy.

The new findings provide "grounds for cautious optimism" about the use of
exercise therapy as an alternative treatment for depression, Dr. F. Dimeo,
of the Benjamin Franklin Medical Center, in Berlin, Germany, and colleagues
conclude in the April issue of the British Journal of Sports Medicine.

The investigators studied the effects of aerobic exercise on depression in
12 patients with major depressive episodes ranging from 12 to 96 weeks in
duration. Of the patients, 10 were characterized as having refractory
depression after failing to improve during treatment with at least two
different classes of antidepressants for at least 4 weeks during the
current episode. The intervention consisted of interval training (walking
speed) on a treadmill for 30 minutes a day for 10 days.

Overall, exercise training caused a clinically significant drop in
depression scores during the 10 days. Of the twelve patients in the study,
six demonstrated "substantial" improvements &Mac247; including five of the
patients with refractory depression &Mac247; two demonstrated slight improvements
and four remained unchanged.

Moreover, there was a high rate of acceptance of the intervention among the
group, Dr. Dimeo told Reuters Health. "Indeed, several patients asked to
continue the training program after the study was concluded."
The study director added that many questions remain about the role that
aerobic exercise should play in the treatment of depression.

exercise may certainly be used as complementary therapy in severely
depressed patients who receive antidepressants and do not have
contraindications for exercise. Since there is no evidence about the
long-term effects of exercise [and] compliance and outcomes when stopping
training, aerobic exercise should not be used as first-line therapy for
depression until confirmatory studies have been concluded."

Dr. Dimeo noted that the team has already initiated a larger, randomized
trial of aerobic exercise in depression. Preliminary results from this
study, he said, "are very promising."
