“….exercise prescription is the
successful integration of exercise
science with behavioral techniques
that result in long term program
compliance and attainment of the
individual’s goals.”

8. Factors To Consider When Designing
An Exercise Prescription
• Health status
• Risk factor profile
• Medical evaluation
• Individual’s goals
• Baseline values
• Exercise preferences
• Program design principles
• Adherence factors
9. Why do we care about health
screening and risk stratification?
10. Health Screenings
• Par – Q
• Medical History
Questionnaire
• Coronary Risk factor
analysis
• Disease Risk Classification
• Informed Consent
• Physical Exam
• Lipid Panel and Glucose
Levels
• Blood Pressure
• 12-Lead ECG

For pregnancy, p. 196 (ACSM)
• AHA/ACSM Health/Fitness Facility Pre-
participation Screening Questionnaire
▫ Figure 2.2, p. 25 (ACSM)
12. Professionally Guided Screening

programming conducted and supervised by
appropriately trained personnel
• Professionally guided screening includes:
▫ Coronary Risk factor analysis
▫ Review more detailed health/medical hx info and
risk stratification
▫ Detailed recommendations for PA/exercise,
medical exam, exercise testing, physician
supervision

Weight: 180 lbs
Height 5 ft. 8 in.
What is the client’s BMI classification?
Weight: 257 lb
Height 5 ft. 9 in.
What is the client’s BMI classification?

3 days per week, for the last 6 months. Her height is
5’2” and she is 130 lbs and her waist circumference
is 33”. Her cholesterol and glucose levels are all

30. Table 2.1 ACSM Risk Stratification Categories for
Atherosclerotic CVD (Figure 2.4 ACSM p. 28)
31. • CVD, pulmonary, or metabolic disease
▫ CVD: Coronary, peripheral vascular, or
cerebrovascular disease
▫ Pulmonary: COPD, asthma, interstitial lung
disease, cystic fibrosis
▫ Metabolic: diabetes (I or II), thyroid disorders,
renal, or liver disease
Cardiovascular, Pulmonary, and
Metabolic Disease - - HIGH RISK!
32. Major symptoms or signs suggestive of cardiopulmonary or metabolic
disease.*
___________________________________________________
1. Pain, discomfort (or other anginal equivalent) in the chest, neck, jaw,
arms, or other areas that may be ischemic in nature
2. Shortness of breath at rest or with mild exertion
3. Dizziness or syncope (fainting)
4. Orthopnea/paroxysmal nocturnal dyspnea (labored breathing;
discomfort in breathing in any but erect position)
5. Ankle edema
6. Palpitations or tachycardia
7. Intermittent claudication
8. Known heart murmur
9. Unusual fatigue or shortness of breath with usual activities
___________________________________________________
*These symptoms must be interpreted in the clinical context in which they
appear, since they are not all specific for cardiopulmonary or metabolic
disease. See description of each in ACSM Guidelines.

35. Exercise Testing and Participation
Recommendation Based on Risk
• Once risk classification established,
appropriate recommendations may be made
regarding:
36.
37.
38. Maximal Graded Exercise Test (GXT),
Reasons for Max. Testing in the Clinical Setting:
To find the true max. HR for exercise prescription
To measure or estimate VO2 max.
To determine baseline aerobic fitness level
To help plan a safe and effective exercise program
To aid in the diagnosis of CVD in the mod. risk or in
those who are symptomatic (*with ECG*)
To follow the progress of known disease (*with ECG)
40. • Sheri is a low risk client. She was told by her
previous trainer that she should not have a GXT
done because according to ACSM GXTs are only
for moderate to high risk clients.
• Do you agree or disagree with her previous
trainer? Why?
43. Factors To Consider When Designing
An Exercise Prescription
• Health status
• Risk factor profile
• Medical Evaluation
• Individual’s goals
• Baseline Values
• Exercise preferences
• Program Design Principles
• Adherence factors
44. Purpose of Health Related Fitness
Testing
• Educate participants about present health-
related fitness status relative to standards and
age and gender norms
• Provide data helpful in development of exercise
prescriptions
▫ Address all fitness components
▫ Baseline data and follow – up
▫ Motivate participants
▫ Stratify risk
45. Components of Health Related Fitness
1. Body weight and body composition
2. Cardiorespiratory Endurance (Fitness)
3. Muscular Endurance
4. Muscular Strength
5. Flexibility
48. Cardiorespiratory Endurance (CRE) /
Cardiorespiratory Fitness (CRF)
• Ability of heart, lungs, and circulatory system to
supply O2 and nutrients effectively to working
muscles
• Typically expressed as VO2max
• Clinical submaximal and maximal tests
▫ Field tests
52. Components of Health Related Fitness
1. Body weight and body composition
2. Cardiorespiratory Endurance (Fitness)
3. Muscular Endurance
4. Muscular Strength
5. Flexibility
54. Prediction equations
• To whom is equation applicable?
▫ Population specific vs. general
• How were variables measured by the researchers
who developed equation?
57. What should be the
proper order of testing?
• Flexibility
• Body composition
• Muscular fitness
• HHQ/Risk stratification
• CRE / CRF
• Resting BP and HR
58. Give client specific instructions as
to what to wear, what to bring, and
what to expect on testing day!
59. Always have your supplies
and equipment ready
before the client arrives!
62. Test Interpretation
• Calculate necessary values
• Classify client results by comparing to
established norms or percentile rank
• Discuss results with clients
▫ Provide hard copy of results to client
▫ Keep a copy for your records!

If you come into my office, and I have never met or spoken with you, I have no idea what you need, want, in terms of activity, exercise or fitness. To do this I need to learn more about you, your health, goals,

A CODFISH
Low Risk: Asymptomatic men and women who have < 1 CVD risk factor from Table 2.3 Moderate Risk Asymptomatic men and women who have > 2 CVD risk factors from Table 2.3 High Risk Individuals who have know CVD, pulmonary, or metabolic disease OR 1 or more signs and symptoms listed in Table 2.2
Girth measurements : Useful for obese people who may be uncomfortable with skinfold measurements or underwater weighing. Pattern of BF distribution imp. predictor of health risks of obesity
Estimated vs. actual Submaximal and maximal Graded exercise tests (GXTs) Field tests Maximal testing in clinical setting To aid in the diagnosis of CVD in moderate risk individuals or in those who are symptomatic To determine the safety of an exercise program To follow the progress of known disease To find the true max. HR for exercise prescription To measure or estimate VO2 max. To help plan a safe and effective exercise program Submax Evaluate progress and provide feedback. Use as a basis for educating clients about concepts of fitness. MAY provide a basis for exercise prescription. Sub-max. cycle ergometer test (Astrand-Rhyming or YMCA Protocol): Used to estimate VO 2 max. from heart rate at a sub-max. workload. 2. Step test: Can estimate VO 2 max. from heart rate achieved after stepping for 3 minutes. 3. Cooper’s 1.5 mile or 12 minute run Can estimate VO 2 max. from time for 1.5 mile run or distance completed in 12 minutes. 4. Rockport 1 mile walk test: Can estimate VO 2 max. from heart rate after walking 1 mile.
Muscle strength Max force or tension Muscle endurance Maintain submax force over time
Test of trunk flexion, measures low back & hip flexibility, common measure of overall flexibility.
Test may have high reliability but not high validity – sit and reach test – poor validity as a measure of lower back flexibility
