The Association Between Physical Education and Symptoms
of Attention Deficit Hyperactivity Disorder
Lucy Barnard-Brak, Tonya Davis, Tracey Sulak, and Victor Brak
Objective: The purpose of the current study was to examine the association between structured physical activity,
specifically physical education, and symptoms of Attention Deficit Hyperactivity Disorder (ADHD). Physical
activity may be associated with lower levels of symptoms of ADHD and this rationale provided the impetus
for the current study. Methods: A community-based, nationally representative sample of children from the
Early Childhood Longitudinal Study, Kindergarten cohort (ECLS-K) was used. Structural equation modeling
was used to examine the association of physical activity with symptoms of Attention Deficit Hyperactivity
Disorder. Two random subsamples were drawn for the purposes of cross-validation of our model. Statistics
reflecting model fit are reported. Results: With a standardized path coefficient value of –.23, findings from
the current study indicate a significant, inverse association between physical education, as a structured form
of physical activity, with the symptoms of Attention Deficit Hyperactivity Disorder in children. Conclusions:
Using a community-based, nationally representative sample of children aged 5 to 7 years old from the United
States, the results of the current study suggest that physical education, as a structured form of physical activity,
may be considered as associated with lower levels of symptoms of ADHD across time.

Attention Deficit Hyperactivity Disorder (ADHD)
has been reported as affecting approximately 1 in 20
school-aged children.
1
This number is equivalent to
having 1 child in every classroom across the nation
having ADHD. In fact, ADHD is one of the mostly com-
monly diagnosed childhood psychiatric disorders.
2
The
symptoms of ADHD have been typically characterized
by developmentally inappropriate levels of inattention,
hyperactivity, and impulsivity that cause significant
impairment in daily functioning.
1
Needless to say,
these symptoms that characterize ADHD can present
challenges for children in school often translating into
inappropriate behaviors such as difficulty taking turns,
excessive talking, interrupting others, and excessive
motor activity. The symptoms of ADHD have also been
associated with poorer outcomes for children with ADHD
as compared with their typically developing peers such
as increased behavioral problems,
3
higher likelihood of
substance abuse issues,
4
lower academic achievement,
5
and higher rates of criminal recidivism.
6
The 2 most commonly implemented treatments for
addressing these difficulties and challenges experienced
by children with ADHD include drug or pharmacological
therapy (eg, stimulants) and behavioral interventions.
7
The use of drug treatment continues to be an issue of con-
troversy in addressing the challenges faced by individuals
with ADHD. This ongoing controversy has been aptly
termed as the Ritalin wars.
8
In fact, several studies have
demonstrated that parental perspectives of drug treatment
options are not consistently favorable. Efron, Jarman,
and Barker
9
indicated that many children had negative
feelings toward medications while Doherty et al
10
found
that approximately half of their sample of children with
ADHD reported that they would stop taking medication
if provided the choice.
Regardless of the evidence that nonpharmacological
treatments appear to be the preferred treatment option
for many parents and children, medications, in the form
of stimulants typically, continues to increase as a treat-
ment option for ADHD.
11
Therefore, it is imperative
that effective behavioral interventions are identified that
are easy to implement so that parents and practitioners
may have a variety of options that suit their preferred
treatment choices with respect to the child such as the
inclusion of exercise. The link between low motor pro-
ficiency and ADHD has been well documented, but less
research has investigated the effects of motor activity on
the behavior related to ADHD. Exercise has been found
to increase brain-derived neurotrophic factor (BDNF),
which is associated with neurogenesis, or the generation
of brain tissue.

By enhancing the ability to encode,
exercise such as methods employed in dance and move-
ment therapy may also contribute to improvement in
measurable behaviors like concentration, hyperactivity
