Paying attention all day in school as
a kid isn’t easy, especially for those who are at a higher risk of ADHD, or
attention deficit hyperactivity disorder.
A new study from Michigan State
University and University of Vermont researchers shows that offering daily
before-school, aerobic activities to younger at-risk children could help in
reducing the symptoms of ADHD in the classroom and at home. Signs can include
inattentiveness, moodiness and difficulty getting along with others.
The study can be found in the Journal
of Abnormal Child Psychology.
“Early studies suggest that physical
activity can have a positive effect on children who suffer from ADHD,” said
Alan Smith, chairperson of MSU’s Department of Kinesiology, who conducted the
research along with lead author Betsy Hoza, a psychologist from the University
of Vermont.
Previous MSU research has shown
improved brain function and better math and reading skills in elementary
students who were exposed to a bout of physical activity. Yet, it’s not as
widely known how consistent exercise might improve the broad range of symptoms
and impairments associated with the disorder.
Over a 12-week period, Smith and Hoza
studied about 200 early elementary school students ranging from kindergarten to
second grade that either exhibited signs of ADHD or didn’t. During the trial,
students were randomly selected to participate in a group that completed
moderate to vigorous physical activity each day before school, or a group that
completed more sedentary classroom-type activities.
“Although our findings indicated that
all participants showed improvements, children with ADHD risk receiving
exercise benefited across a broader range of outcomes than those receiving the
sedentary activities,” Smith said.
Smith indicated that further studies
are needed to better understand the frequency and amount of physical activity
that can provide benefits to children and added that the effects of exercise
may be different based on a child’s age.
“Despite the number of remaining questions, physical
activity appears to be a promising intervention method for ADHD with well-known
benefits to health overall,” he said. “This gives schools one more good reason
to incorporate physical activity into the school day.”
