counseling on Physical Activity
10. Efficacy of Physician Counseling
• Recent study of hypertensive patients, only a
third received counseling to engage in physical
activity as a way to manage their
hypertension.
• However, 71% of the patients who were
counseled followed the recommendations to
exercise and reduced their blood pressure.
– Halm, Ethnicity and Disease 2008
11. • A recent study showed that diabetic patients
received counseling/referral for nutrition only
36% of the time, and for exercise only 18% of
the time.

15. Our Obligation
• The physician is obligated to broach critical
lifestyle areas.
• Avoidance or lack of comment by the
physician may be perceived as tacitly
condoning the unhealthy behaviors.
• The physician has an important opportunity to
promote behavior change and be supportive
of the change process.
• Need to ask about physical activity and to
prescribe exercise.
16. • Effective and efficient delivery of message
from physician to improve health behaviors.
“Talk the Talk.”
• Need to establish physicians as role models of
healthy behaviors. “Walk the Walk.”

problem: the epidemic of
overnutrition.” WHO
It is estimated that by 2020 2/3rds of the global
burden of disease will be attributable to chronic
non-communicable diseases, most of them strongly
associated with diet. The nutrition transition towards
refined foods, foods of animal origin, and
increased fats plays a major role in the current
global epidemics of obesity, diabetes and
cardiovascular diseases, among other non-
communicable conditions. Sedentary lifestyles and the use
of tobacco are also significant risk factors. …….. A

enhancement of health and/or
improvement of function
53.
54. Exercise
• Leisure time Exercise: organized sports,
running, gym activities, rehabilitation etc.
• Lifestyle Exercise: activity incorporated into our
daily pattern of life
– eg: parking in the distant portion of the parking lot rather then the first
bumper, taking the stairs instead of the elevator etc.
55. Types of Physical Activity
• Cardiovascular
• Strength/Resistance Training
• Core Stability/Balance
• Flexibility/Coordination
57. Cardiorespiratory Adaptations
• High, acute stress to the CV system

58. Immune System Changes/Adaptations
• Beneficial Effects: Regular, Moderate
• Harmful Effects: Extreme, Excessive
– Decr. neutrophil respiratory burst, lymphocyte
proliferation, monocyte antigen presentation
– >1.5 h, of moderate to high intensity (55–75%
maximum O2 uptake), and performed without
food intake
60. Basic Principle
• Progressive Overload: (Delorme Principle)
– Gradual increase in stress upon the body results in increases
in tolerance and eventual plateau
– SAID (Specific Adaptations to Imposed Demands)
– Greater Demand = Greater Adaptation within genetic
potential
61. Basic Principles
• Hyperplasia: Inc in the number of muscle
fibers within a given muscle ≈ 5%
• Hypertrophy: Inc in the size of individual
muscle fibers/or an entire muscle ≈ 95%

100. The Pre-contemplators
• Ask if the patient would
like to hear about or
read about the benefits
of exercise
• “I understand that you
are not ready to change,
but please know that
when you are ready, I will
be here to help.”
• “I think that it is
important for your
health….”
Key: Empathy
101. Physicians’ Empathy Influences Clinical
Outcomes
• 891 Diabetic patients

123. Breakout: 4 minutes
• Ask your neighbor about their physical activity
goal
• With this in mind, write an Exercise
Prescription for your neighbor using the FITT
approach
124. Practical Advice:
• Not counseling the benefits of exercise may be
perceived as condoning a sedentary lifestyle.
• Do not emphasize exercise threshold.
• Change the emphasis from vigorous to moderate
intensity e.g. walking 3-4 miles per hour.
• Sedentary patients should not be counseled to
initially exercise at a hard level as this leads to higher
dropout rates.
125. Motivating your patients
• Set realistic goals- accumulating moderate
activity (e.g., pedometer)
• Talk about general and mental health benefits
of exercise and risks of remaining sedentary,
but also about the pleasure of exercise
• Ask about physical activity levels.
• Write exercise recommendations on a script
126. Motivating your patients
at each visit:
• Ask about exercise just as inquiries about
sleep, concentration, etc.
• Document details in chart note
• Explore barriers to exercise
• Positive reinforcement
• Incorporate socialization
127. “Physical fitness can neither be
achieved by wishful thinking nor
outright
purchase.”
Joseph Pilates
133. CDC Exercise Stats
• <20% of all adults achieve recc. Levels
• > 60% of adults are not regularly active
• By age 75 1:3 men and 1:2 women engage in NO
physical exercise
134. • “You have to work at living, period. You’ve got
to train like you are training for an athletic
event. Most older people just give up. They
think, “I’m too old for that,” because they
have an ache here or a pain there. Life is a
pain in the butt; you’ve got to work at it.”

Notas do Editor
Marcus et. Al. “Training physicians to conduct physical activity counseling” 1997. We successfully overcame some of the barriers to physician based exercise counseling including lack of counseling skills, perceived ineffectiveness and lack of confidence in counseling.” “The time spent in counseling was relatively brief (5 minutes) and yet, results demonstrated a significant improvement in self-reported levels of physical activity.”
Halm J, Amoako E. Physical activity recommendation for hypertension management: does healthcare provider advice make a difference? Ethnicity and Disease 2008 Summer; 18(3): 278-82.
This is an exercise prescription that was signed by…Dr. Robert Sallis, The past President of the ACSM. This prescription appeared in the November/December issue of a magazine called Fitness. Dr. Sallis was interviewed about exercise is medicine and he included this visual. Your patients might read this and have question. They might even ask you for a prescription. So let’s get familiar with exercise prescriptions.

Some people think only of sports teams, athletics events, lengthy workouts in expensive gyms etc….not the case Others try to say the activity must be planned, directed etc….but I disagree…..

Highest force on the muscle with a rapid eccentric contraction……..
Untrained…….can only fire around 71% of muscle csa
Enthesis…..tethers…pulling on bone may be component of dynamic bone changes……
cortisol = catabolic……..lipolysis 3-4 forms of GH…..various kiladaltons
Prochaska: Trantheoretical model of change
Example…if you take up running for the first time…success should not be running a marathon in 2 hours……rather 15 minutes without running may be a legitimate goal etc
