NEW YORK (Reuters Health) - Regular exercise may improve depression symptoms in people who've failed to get better with antidepressant medication, the results of a small study suggest.
The study found that depressed women who started a supervised exercise regimen had significant improvements in their symptoms over the next 8 months. Those who didn't exercise showed only marginal improvements.
Before the study, all of the women had tried taking antidepressant medication for at least two months but had failed to improve.
A number of studies have found that physically active people are less likely than couch potatoes to suffer depression. Some clinical trials have shown regular exercise can help treat the disorder, and perhaps be as effective as antidepressant drugs in some cases.
The new findings suggest that exercise can even help people whose symptoms have been resistant to medication, according to the study authors.
