Pre-participation Health Screening Purpose
• Identification individuals w/
– medical contraindications to exercise
– ↑d risk for disease
• age, symptoms, &/or risk factors
• medical evaluation & exercise testing before starting
an exercise program
– clinically significant disease
• participate in medically supervised exercise pgm
– other special needs

Parts of Informed Consent for Exercise
Training
• Purpose & explanation of procedure
– What are they consenting to
– What does it consist of or include
– What are they agreeing to
– Expectations of program & participant
– State that participant has been advised
Consent
• Legally effective agreement of the participant
or the participant’s legally authorized
representative based on information that is
given to the participant or the representative
in language that is understandable.
Parts of Informed Consent for Exercise
Training
• Risks
– Adverse Δs during exercise
• Abnormal BP
• Fainting

• Stroke
• Heart attack
• Death
– Efforts made to minimize occurrences
– Knowing of these risks, it is my desire to proceed
Parts of Informed Consent for Exercise
Training
• Benefits
–May or may not obtain health or
fitness benefits
–But, list likely benefits of exercise
training

Exercise Training
• Alternatives available
–Not attend

• Does provide evidence that client
was made aware
• Negligence – not covered
• Legal counsel
Pre-activity Screening
• Gathering
– Demographics
– Health-related information
• Aid decision making for assessment &
exercise
Preparticipation Health Screening &
Risk Stratification
• American College of Sports Medicine (ACSM)
• American Heart Association (AHA)
• American Association of Cardiovascular &
Pulmonary Rehabilitation (AACVPR)
Therefore; Preparticipation Health Screening
Include
• Medical contraindications to exercise
• ↑d risk for disease
– Age
– Symptoms
– Risk factors
• Clinically significant disease
• Special needs
Health Screening
Self-administered questionnaires
Sophisticated diagnostic tests
Health Screening
Nature & extent of appraisal
• Age
• Sex
• Perceived health status of participants
• Resources
– Economic
– Personnel
– Equipment
Components of Pre-Activity
Screening
• Medical History/Health Habits
Questionnaire
• Physical Activity Readiness
Questionnaire (PAR-Q)
• Medical/Health Exam
Health History Questionnaire
•
•
•
•
•
•
Family Hx
History of diseases & illnesses
Surgical History
Past & present health habits
Medications
Signs & symptoms
– (next slide – review p 25)
Physical Activity Readiness
Questionnaire (PAR-Q)
(
Recommended as a minimum standard
for entry into moderate-intensity
exercise programs
Designed to identify small number of
adults for whom PA might be
inappropriate
(next slide – review p 26)
Physical Assessment & Laboratory Tests
• Resting HR
• Resting BP
• Lung Capacity
–FVC
–FEV1
–MVV

Blood Tests
• TC
• LDL
• HDL
• TC/HDL Ratio
• Glucose

Signs & symptoms
Initial ACSM
Risk Stratification

threshold from Table 2-1 (p 20)
Initial ACSM
Risk Stratification
• Moderate risk
–Older individuals
• men 45 years of age
