A physically active child is a healthy child.
Physical activity strengthens a child’s muscles and bones,
prevents excessive weight gain, and reduces the risk of diabetes, cancer, and
However, physical activity is also beneficial to the mental
health of a child.
Experts say physical activity allows children to have a better
outlook on life by building confidence, managing anxiety and depression, and
increasing self-esteem and cognitive skills.
“Exercise also releases endorphins, which correlates to a
happy child,” said Len Saunders, physical health educator, and author of “Keeping
Kids Fit” and “Buddy and Bea.”
The benefits of physical activity for children are in the
spotlight this week after two studies were published Monday in the journal Pediatrics.
Both analyzed the positive effects of exercise on children’s
What exercises does
concluded that moderate to vigorous physical activity at ages 6 and 8 is linked
to fewer symptoms of depression two years later.
The other study
concluded that cybercycling improves classroom functioning for children with
Cybercycling involves riding a stationary bike while looking
at virtual reality scenery.
So why cybercycling and not just cycling?
Children with behavioral health disorders (BHD) demonstrate
low participation in aerobic exercise, and cybercycling was critical because
the children found it engaging.
“In terms of the physiology, there is no reason to believe
that any aerobic exercise — regular cycling, running, etc. – wouldn’t have
these effects. But getting children to engage in it if they don’t enjoy it is
very challenging,” April Bowling, assistant professor at Merrimack College, explained
Many of these children have sensory disorders, social
anxiety, and delays in developing motor skills, so it’s difficult to make
traditional sports and exercise programs attractive to them.
“The cybercycling appealed to them because they could engage
in it successfully at their current ability level, and they found the video
games and virtual reality courses entertaining. When you are chasing dragons
and collecting points, you can easily forget how hard you are working,” said Bowling.
Research shows exercise improves mood and behavior in
children and lowers chronic disease risks, but there is little research on
educational settings serving children with complex BHD, the study explained.
By using a randomized controlled crossover design,
researchers investigated whether an aerobic cybercycling physical education
curriculum could successfully engage and improve behavioral regulation and
classroom functioning among children and adolescents with complex BHD.
Students diagnosed with autism, attention deficit hyperactivity
disorder (ADHD), anxiety, or mood disorders were randomly assigned to use the
bikes twice a week during 30- to 40-minute physical education classes.
Researchers found the program to be successful as children
gradually increased their riding time and intensity over seven weeks.
“Overall, children in the intervention group, who ranged in
ages 7 to 16, displayed up to 51 percent less disruptive behaviors than during
the control period, with the effect particularly strong on the days they
participated in the cybercycling class,” the study reports.
Saunders was particularly interested in the cybercycling
study as the visual stimulation acts as a great motivation to exercise. “I
think the cybercycling study was wonderful. The children in the study were
visually stimulated in a unique way that motivated them to exercise,” Saunders
told Healthline. “It was something that was enjoyable to them, which was a nice
reward at school. There appears to be a direct correlation between this type of
exercise and improvement in behavioral health.”
Changing the brain
Researchers believe that aerobic exercise acts in different
ways that can help improve mood and behavior in children and adults.
“First, it seems to change where the brain directs its
resources, from areas of the brain that are involved in worrying, for example,
and toward areas that are more involved in coordination and focus,” said
Bowling. “Secondly, aerobic exercise can change brain chemistry, and
specifically the levels of certain neurotransmitters that might help improve an
individual’s self-regulation. When mood and self-regulation — the ability to
control behavior — is improved, then children can function better in the
Bowling believes there is a lot of promise for cybercycling
to be used in more settings. She added they’re currently testing their use in
public special education classrooms, but there’s a problem in getting these expensive
bikes into schools that can’t afford them.
“Cost is an issue for many schools, and kids need access to
different types of exercise, so I think an important area of research will be
also testing other engaging modes of aerobic exercise that could be similarly
effective but less expensive,” Bowling said.
Bowling emphasized the study adds to mounting evidence that
kids with behavioral health challenges benefit from exercise — not just
physically, but mentally.
“I think it’s absolutely critical that we stop cutting out movement
from the school day — taking time away from recess and physical education for
more academic purposes — if we want our children to perform to their
potential,” said Bowling.
Battling depression, anxiety
The other study focused on physical activity, sedentary
behavior, and symptoms of major depression in middle childhood.
“Physical activity, and particularly moderate-to-vigorous
physical activity [MVPA], has a positive effect on reducing future depressive
symptoms in middle childhood,” said Tonje Zahl, M.S.C., of the Norwegian
University of Science and Technology, and the study’s lead author.
In addition, increasing physical activity may serve as a
complementary method in treating childhood depression.
“Physical activity has a range of health benefits, and this
study indicates that increasing children’s moderate and vigorous physical activity
may prevent later depressive symptoms,” said Zahl in a statement. “Thus,
increased physical activity may serve as an adjunct component to … pharmacological
or psychological treatments. As regards prevention, because nearly all children
can be targeted in efforts to increase MVPA, the gains at the population level
might be substantial.”
Physical educators agree that physical activity may prevent
“Exercise has a positive effect on creating mentally healthy
children by releasing feel-good brain chemicals that may ease depression,” said
Dr. Christina Hibbert, clinical psychologist, and author of “8
Keys to Mental Health Through Exercise,” believes in physical activity as a
means of therapy. Exercise has helped her overcome depression and anxiety.
“Personally, I’ve used cardiovascular exercise to help me
overcome struggles with depression, and strength training/flexibility exercises
have helped me overcome anxiety,” Hibbert told Healthline. “Being in the sun, getting
out of the house, and moving my body had a profound effect on my mood, and I
started to see that it was key in helping me feel emotionally and mentally
stronger and healthier.”
Other mental health conditions
As a psychologist, Hibbert teaches her clients how to use
physical activity to not only prevent mental and physical illness, but also to
help treat other conditions, including grief, heartache, bad moods, and even
relationship and family problems.
“I’m such a believer in the power of the mind-body-spirit connection,”
“Physical activity is
one of the best things we can do to ease the effects of most mental health
conditions, including bipolar disorder and schizophrenia,” Hibbert said. “Though
adherence to an exercise program might be more challenging for those suffering
from mental health conditions, if they can learn the mental skills to stay
motivated and stick with it, regular exercise can be one of the most powerful
additions to treatment,” she added.
Hibbert noted that the two studies are in-line with other
research showing the powerful effects of exercise on the brain, behavior, and
mental health. “When we move our body, we move our mind. That might mean moving
excess mental energy that would otherwise lead to behavioral issues and
disruption, or it might mean moving us out of a state of feeling depressed.
Exercise not only offers the healthy calm energy we need for
optimal behavior, it also allows us to work out stressful, anxious energy that
may interfere with daily life,” she said. “Being active and moving our body
daily can carry the incredible mental health benefits like greater mental
clarity, energy, focus, creativity, insight, etc., into our teen and adult
years,” said Hibbert.
Both Hibbert and Saunders agree that the younger we start
exercising the better off we’ll be later on in life, and it’s never too late to
start. They also urge parents to take part in their children’s physical
“Adults that work with children play an important role in
the growth and development of children. Being that ‘healthy role model’ will
not only help them stay physically fit, but mentally fit,” said Saunders.
“One of the best ways to help our children be more active is
to start a habit of activity ourselves and include our children,” added
Hibbert. “Play, ride bikes, jump on the trampoline together with your child — whatever
you can do to get your children — and you — moving, and make it fun, is going
to be just right. This shows children that moving is fun, it makes them feel
good, and it also strengthens our family bonds.”
