Lecture Overview
• Discuss the paradox that exists in
youth fitness and sports today.
• Review the wide ranging benefits
of PA in kids and implications of an
inactive youth population.
• Talk about current messaging on
youth health behaviors
• Discuss the role of the physician
and healthcare systems in
assessing and prescribing exercise.
Youth Fitness and Sports Paradox
• Survey of HS seniors:
– Less than 25% of boys and 15%
of girls exercise vigorously .
– Childhood obesity is an
emerging epidemic.
• However;
– Half the exercising group is
actively involved on an athletic
team, many participating all
year.
– Increased risk for orthopedic
injury, especially related to
overuse.
Youth Fitness and Sports Paradox
• The Changing Landscape
of Playgrounds!
– Most exercise obtained by
children in America is no
longer obtained in physical
education class or free
play; it comes through
organized youth sports.
– Children are less fit and
obesity is growing, yet so is
athletic injury!
Physically Inactive kids at greater risk
for injury!
• Study of 995 children aged 9-12
years.
– Low levels of habitual PA have
significantly increased injury risk.
• The children at highest injury risk
are the target audience of the
contemporary PA promotion
efforts.
• Therefore, PA promotion should
focus on injury prevention as well.

Benefits of Physical Activity in Kids
Why Kids Should Exercise
• Compared to kids who don’t
exercise, kids who do:
– Can run longer and faster
– Have stronger bones
– Have stronger muscles
– Are less likely to be fat
– Have less stress and depression
– Are less likely to develop chronic
diseases
– Are more likely to be healthy
adults
Exercise Helps Prevent:

Diabetes
Cancer (breast and colon)
High blood pressure
Depression
Osteoporosis
Alzheimer’s disease
Heart attacks
Dying early
Physical Activity Improves Mental
Health
• Regular PA may increase self
esteem
• Regular PA may decrease
anxiety/depression*
• Some evidence shows teen girls
have lower rates of sexual activity
and pregnancy when PA increased
• Some evidence regular PA
associated with decreased
smoking, alcohol and drug abuse

Fitness and Neurocognitive Function
in Preadolescent Children
• 24 children, mean age, 9.6 years
• Fitness assessed by FITNESSGRAM
• Neurocognitive function assessed by
responses to a stimulus discrimination task
• Fitness was positively associated with
attention, working memory, response speed,
and cognitive processing speed
Hillman CH et al. Med Sci Sports Exerc 2005; 37:1967
How Much Physical Activity Do Kids Need?
• Children and adolescents should do 60 minutes
(1 hour) or more of physical activity daily.
– Aerobic Activities: most should be either
moderate or vigorous intensity PA. Include
vigorous-intensity PA at least 3 days per week.
– Muscle-strengthening Activities: at least 3 days of
the week, as part of the 60 or more minutes.
– Bone-strengthening Activities: on at least 3 days of
the week, as part of the 60 or more minutes.
• Activities should be age-appropriate, enjoyable, and
offer variety.
Kids exercise less as they get older

Obesity Hysteria
• The world has now been
sufficiently alerted to the
global problem of obesity.
• Patients have been
labeled and stigmatized.
• Assigned lots of blame.
• Spent lots of money.
• …and gotten nowhere.
Are patients and their physicians giving up?
• Data from National Ambulatory Medical Care
Survey for 1995-96’ and 2007-08’ showed:
– During this period, adults who were overweight or
obese increased from 52.1% in 95’ to 63.3% in 08”.
– Patients seen in 2007-08; had 46% lower odds of
receiving weight counseling than 95-96’.
– Patients with hypertension 46% less likely and diabetics
59% less likely to receive counseling.
• The campaign on obesity is not working!
• What’s the definition of insanity?
Kraschnewski, et al, Medical Care, 2013
We need a new (and fresh) approach!
• We need to give patients
permission to be fat; And still
be healthy!
• Shift focus off of BMI and
onto physical activity.
• Health At Every Size (HAES)
– Focus on broader health.
– 95% regain lost wt. in 3-5 yrs.
– Change in BMI is not a success
measure for an exercise
program.

What can we do?
• Large scale exercise prescription
initiative in adults and kids:
– Every patient; Every visit;
Every treatment plan.
• Physical activity should be
recorded as a vital sign and kids
encouraged to do 60 min of
exercise per day.
• Message should be the same from
every medical provider.
• We must begin to merge fitness
with healthcare.

What Can Busy Physicians Do to
Encourage Physical Activity?
 0 Minutes:
Running late? Too many other concerns on the patient’s
list? Relax. Perhaps you can discuss physical activity at
next visit. Hopefully office staff will have assessed
exercise and provided resources.
1 Minute for Advice:
Quickly congratulate kids (and their parents) who are
getting 420 minutes or more per week of moderatevigorous physical activity.
Advise patients who are getting fewer than 420 minutes
of the importance of physical activity, especially linking
benefits to the child’s complaints, problems and health
risks.
What Can Busy Physicians Do to
Encourage Physical Activity?
2 Minutes for a Prescription:
 Review key messages about the importance of physical
activity.
 Offer a generic Exercise Prescription.
 Suggest useful ideas (e.g. walk to school, bike transportation,
active games, after-school activity, family fitness activities).
5 Minutes for Brief Counseling:
 Assess readiness for change regarding exercise habits.
 Ask what the child might want to do to be more active and
barriers to prevent this from happening -- brainstorm on
how to get around them.
 Explain to parents in detail how exercise affects health and
development and their child can go about incorporating it
into their life.

Summary
• Youth sports/activity paradox – kids are doing
too much or too little.
• The wide ranging benefits of PA in kids and
adults are well established.
• We need to encourage kids to be Healthy at
Every Size by engaging in regular PA.
• Physician have an important role to play in
promoting PA for health
– An Exercise Vital Sign is an easy way to bring a
discussion on PA into the exam room.
– Even brief advice can have a significant affect.
