COMMON RISK FACTORS FOR MAJOR
NON-COMMUNICABLE DISEASES
Unhealthy diet
Physical inactivity
Tobacco use
-WHO
Non-Communicable Diseases
Cardiovascular diseases (CVDs)
Diabetes
Obesity
Cancer
Chronic Obstructive Pulmonary Disease
(COPD)
Death from NCDs
60% of 58 million deaths annually
80% of deaths occur in low and middle
income countries
o 23% WHO African Region
o 78% Americas
o 52% Eastern Mediterranean
o 86% European Region
o 54% Southeast Asian Region
o 78% Western Pacific Region
-WHO, 2008
PHYSICAL INACTIVITY
(lack of physical activity)
4th leading risk factor for global mortality
Estimated to be the main cause for
approximately
o 21-25% of breast and colon cancers
o 27% of diabetes and
o ~30% of ischemic heart disease
burden
Figure 1. Prevalance of insufficient physical
activity
PHYSICAL ACTIVITY AND HEALTH
(+) Protective effects between
physical activity and risk for several
chronic diseases
Low levels of habitual physical
activity and low levels of physical
fitness are associated with markedly
increased all-cause mortality rates.
HEALTH BURDENS THAT COULD BE
REDUCED THROUGH PHYSICAL
ACTIVITY
13.5 million people have coronary
heart disease
1.5 million people suffer from a heart
attack in a given year
8 million people have adult-onset
diabetes
95, 000 people are newly diagnosed
with colon cancer each year
250, 000 people suffer from a hip
fractures each year
50 million people have high blood
pressure
Over 60 million people are
overweight

Physicians, their Patients & Exercise
47% of primary care physicians
include an exercise history as part of
their initial examination
Only 13% of patients report
physicians giving advice about
exercise
Physically active physicians are
more likely to discuss exercise with
their patients
DETERMINANTS OF PARTICIPATION IN
PHYSICAL ACTIVITY
Lack of time is the most commonly cited
barrier to participation in physical
activity
Injury is a common reason for stopping
regular activity
Smokers are more likely than non-smokers
to drop out of exercise programs
DETERMINANTS OF PARTICIPATION IN
PHYSICAL ACTIVITY
Body composition (percentage of body fat)
is not a powerful predictor of physical
activity habits;
o However, persons who are obese
are usually inactive.
Strongly related:
o Confidence in the ability to be
physically active
o Perceived barriers to activity
o Enjoyment of activity
Weakly related:
o Intention to exercise
o Awareness of the benefits of
exercise
Family and friends
o Role models
o Provide encouragement
o Companions during physical activity
BARRIERS:
o Environment/ Urbanization
Fear of violence and crime in
outdoor areas
High-density traffic
Low air quality, pollution
Lack of parks, sidewalks and
sports/recreation facilities
o Technology-reduces the energy
needed for activities of daily living
Excessive television viewing/
social media/ gadgets
PHYSICAL ACTIVITY
o any bodily movement produced by
skeletal muscles that requires
energy expenditure
o includes activities undertaken while
working, playing, carrying out
household chores, traveling, and
engaging in recreational pursuits.
-WHO

FITT PRINCIPLE Basic information to maximize the potential of
physical activity and exercise
Frequency
Intensity
Time
Type of Physical Activity
FREQUENCY
How often?
Number of times per week you engage in
physical activities
INTENSITY
Difficulty or exertion level of your physical
activity
Depends on how hard you have to work to
do the activity
Determined by:
o Target Heart Rate
o Talk Test
Formula for TARGET HEART RATE
Maximum Heart Rate (MHR)
MHR = 220-age
Target Heart Rate: 50-70% of the MHR
more advanced individualstarget heart rate
70-85% of MHR
Example: 40 year old PT
Maximum heart rate:
220 - 40 = 180
Multiply 180 by 50% and 70%
Target Heart Rate:
90bpm 126bpm
TALK TEST
ability to carry on a conversation while
doing a physical activity
a person doing
o moderate intensity activity can
talk but not sing
o vigorous intensity activity cant
say more than a few words without
stopping for a breath

LIGHT INTENSITY
MODERATE INTENSITY
VIGOROUS INTENSITY
Common daily activities that dont require much effort
Make the heart, lungs, and muscles work harder than light-intensity activities
Make the heart, lungs, and muscles work very hard.
Scale of 0-10; activity is a 5 or 6
Scale of 0-10; activity is a 7 or 8
MODERATE INTENSITY ACTIVITIES
Walking briskly (3 miles/hr or faster,
but not race-walking)
Water aerobics
Bicycling slower than 10 miles per
hour
Tennis (doubles)
Ballroom dancing
General gardening
VIGOROUS INTENSITY ACTIVITIES
Race walking, jogging, or running
Swimming laps
Tennis (singles)
Aerobic dancing
Bicycling 10 miles.hr or faster
Jumping rope
Heavy gardening (continuous
digging or hoeing)
Hiking uphill or with a heavy
backpack
TIME
How long should you exercise?
Accumulated and continuous bouts of
moderate-intensity physical activity can
provide health benefits
o 30 minutes daily moderate-
intensity activities can be done in:
Five 6-minute intervals
Three 10-minute intervals
Two 15-minute intervals
Time depends on intensity
o Light-intensity activities >
moderate-intensity activities >
high-intensity activities
o Lighter activity the more time
required
Time needed Depends on Effort
Light Effort (60 minutes)
Moderate effort (30-60 minutes)
Vigorous effort (20-30
minutes)
-Light walking -Volleyball -Easy gardening -Stretching
-Brisk walking -Biking -Raking leaves -Swimming -Dancing -Water aerobics
-Aerobics -Jogging -Hockey -Basketball -Fast swimming -Fast dancing
Physical activities do not have to be
strenuous to provide health promoting
benefits
Moving from sedentary to moderately
active provides greatest improvement
in health benefits
4 TYPES OF PHYSICAL ACTIVITY
Aerobic
Muscle-strengthening
Bone-strengthening
Stretching
Aerobic Activity
o moves large musclesarms and
legs
o Examples: running, swimming,
walking, bicycling, dancing and
doing jumping jacks
o also called endurance activity
Muscle-strengthening activities
o improve the strength, power, and
endurance of muscles
-
GUICO, CMA

o examples: pushups and sit-ups,
lifting weights, climbing stairs, and
digging in the garden
Bone-strengthening activities
o feet, legs, or arms support the
bodys weight
o muscles push against the bones
o examples: running, walking, jumping
rope, and lifting weights
Stretching
o helps improve flexibility and ability to
fully move joints
o examples: touching your toes, doing
side stretches, yoga exercises
How much of physical activity is
recommended?
Children and adolescents aged 5-17
years
o Should do at least 60
minutes of moderate to
vigorous-intensity physical
activity daily
o Physical activity of amounts
>60 minutes daily will provide
additional health benefits
o Should include activities that
strengthen muscle and bone,
at least 3 times per week

30 minutes) of moderate-intensity
physical activity throughout the
week, or
o At least 75 minutes (1 hour and 15
minutes) of vigorous-intensity
physical activity throughout the
week, or
o An equivalent combination of
moderate- and vigorous intensity
activity
o Additional health benefits:
Increase moderate-
intensity physical activity to
300 minutes (5 hours) per
week, or equivalent.
o Muscle-strengthening activities
should be done involving major
muscle groups on 2 or more days
a week
FITT Prescription: Adults 18-64 years
Frequency: 1 week
Intensity: moderate intensity
Time: 150 minutes (2 hours and 30
minutes)
Type: Aerobic activity and Muscle and
bone strengthening
How much of physical activity is
recommended?
Adults aged 65 years and above
o Additional health benefits, increase
moderate intensity physical
activity to 300 minutes per week,
or equivalent
o Those with poor mobility: enhance
balance and prevent falls, 3 or
more days per week
o Muscle-strengthening activities
should be done involving major
muscle groups, 2 or more days a
week.
FITT Prescription: Adults 65 years and
above
Frequency: 1 week
Intensity: moderate
Time: 150 minutes (2 hours and 30
minutes)
Type: Aerobic activity and Muscle and
bone strengthening; enhance
balance
OLDER ADULTS
Additional health benefits
o Greater amounts of physical
activity
o Increasing the duration, intensity,
or frequency
Care should be taken not to engage in
excessive amounts of activity risk of
injury
SEDENTARY OLDER ADULTS AND THE
OBESE
Should start with short-intervals of
moderate physical activity (5-10
minutes) and gradually build up to the
desired amount
OLDER PEOPLE
Loss of strength and stamina attributed
to aging is in part caused by reduced
physical activity
Inactivity increases with age
o By age 75, about one in three men
and one in two women engage in
no physical activity
Social support (family and friends)
o Consistently and positively related
to regular physical activity
