New researcher has added further credence to previous studies suggesting that exercise may decrease the symptoms of depression. The study, conducted by the Centre for Clinical Brain Sciences at the University of Edinburgh, reviewed data from 35 trials including a total of 1,356 participants.
The participants, all of whom suffered from clinical depression, worked with physical trainers from the American College of Sports Medicine. Those who got the most exercise reported the greatest relief in symptoms compared with those who had no exercise, or took a pharmacological treatment.
"Exercise is moderately more effective than a control intervention for reducing symptoms of depression, but analysis of methodologically robust trials only shows a smaller effect in favor of exercise. When compared to psychological or pharmacological therapies, exercise appears to be no more effective, though this conclusion is based on a few small trials," the researchers said in their study report.
