Exercise May Help Ease Depression in Teens: Study
Experts note a similar effect has long been noted in depressed adults
By Robert Preidt
SUNDAY, Nov. 10 (HealthDay News) -- Teens can suffer from depression like everyone else, but a small new study hints that exercise might help ease the condition.
The British study included three boys and 10 girls with depression who were enrolled in trainer-led workouts three times a week for 12 weeks. The teens were also encouraged to exercise 30 minutes a day on the other days.
According to the researchers, the workouts were linked to significant boosts in mood, with depression severity cut by 63 percent. Eighty-three percent of the teens who completed the exercise program were no longer as depressed by the end of the study, which was slated for presentation Saturday at the Society for Neuroscience annual meeting in San Diego.
"Exercise has so many advantages as a therapy: It is non-drug, has few side effects and has countless other health benefits. But it has never been tested in youth as treatment for depression," study author Robin Callister, of the University of Newcastle, said in a Society for Neuroscience news release.
"Evidence that exercise can lift mood in young people is a huge step forward in treatment of this delicate population," she added. "We are now conducting a larger trial to further evaluate the effects of exercise in depression and are hopeful that it could be used as a treatment in addition to other treatments for depression without potential problems."
Two experts in the United States said the findings made sense.
"It is no surprise that exercise reduces depression, regardless of age," said Mark Solms, co-chair of the Neuropsychoanalysis Association in New York City. "It is well established that vigorous and protracted exercise raises endorphin levels, and that endorphins [brain chemicals linked to lowered stress] reduce the mental pain of depression no less than they reduce physical pain."
Victor Fornari is director of the division of child and adolescent psychiatry at North Shore-LIJ Health System in New Hyde Park, N.Y. He noted that depression is a "serious medical condition associated with suffering" and also a major contributor to suicides among young people.
