Study: Walking Helps Depressed Patients
AUSTIN, Texas - Just 30 minutes of brisk walking can
immediately boost the mood of depressed patients,
giving them the same quick pick-me-up they may be
seeking from cigarettes, caffeine or binge eating, a
small study found.
Researchers at the University of Texas at Austin
found that people suffering from depression who
walked on a treadmill for 30 minutes reported
feeling more vigorous and had a greater sense of
psychological well-being for up to an hour after
completing the workout.
Those patients and another group that sat quietly
for 30 minutes both reported reductions in negative
feelings such as tension, depression, anger and
fatigue.
But only the group that exercised said they felt
good after the session, according to the study,
published in the December issue of the journal,
Medicine and Science in Sports and Exercise.
Lead researcher John Bartholomew said the study
reinforces past research that has found consistent
exercise, along with medication and counseling, can
help people overcome depression.
However, Bartholomew's is among the first to show
that exercise can have a positive effect right away.
"It's not something you have to do for 10 weeks and
it's not something you have to do at a high
intensity," said Bartholomew, an associate professor
of kinesiology and health education. "You should
derive a benefit very early on in the process, and
hopefully that is the kind of thing that will
motivate them to continue to engage in the
behavior."
The study, funded by Future Search Trials, an Austin
medical research company, involved 40 people between
the ages of 18 and 55. All were recently diagnosed
with major depressive disorder, were not taking
antidepressants and did not regularly exercise.
Twenty patients were assigned to exercise for 30
minutes, while the others sat quietly for the same
amount of time. They were surveyed five minutes
before the session and five, 30 and 60 minutes
afterward.
The positive mood effects from walking were sizable,
lifting their feelings of vigor to near-normal
levels, the study said. But the results were
short-lived, returning to pre-exercise levels within
an hour.
While the study shows depressed people who
self-medicate with cigarettes, caffeine or food
binges could get similar positive feelings from
exercising, experts said it won't be easy to
persuade them to replace bad habits with walking or
shooting hoops. It's hard enough to get healthy
adults to exercise.
"For people who are severely depressed, that may not
be something I'm really going to hang my hat on,"
said Dr. Erik Nelson, an assistant professor of
clinical psychiatry at the University of Cincinnati
College of Medicine.
But for mildly to moderately depressed patients,
exercise may lessen feelings of helplessness and
isolation, he said.
"People shouldn't feel like the only thing they can
do is take their medicine and wait till they feel
better," Nelson said. "This kind of shows there are
things you can do to help yourself in the short
term.
