Understanding the Importance of Pre-Activity Screening for Safe Exercise Participation

Pre-activity screening is essential for identifying individuals with medical contraindications, those requiring medical clearance, and individuals needing supervision during physical activities. Proper assessment takes into account medical history, health habits, and risk factors, including family history and existing health conditions. The PAR-Q form aids in evaluating cardiovascular and pulmonary risks by assessing symptoms like chest pain and dizziness. Following ACSM guidelines, screening helps determine personal risk categories and ensures informed consent, promoting safer exercise practices across various populations.

  1. Pre-Activity ScreeningChapter 2 Chapter 2

  2. Why Screen for Activity? • To identify those with medical contraindications • To identify those who need medical clearance • To identify those who need medical supervision • To identify those with other health/medical concerns

  3. Medical History/Health Habits • Family history • History of illness & disease • Surgical history • Health behaviors (smoking, alcohol, etc) • Current medications • Signs & symptoms suggesting disease

  4. PAR-Q Form (Appendix C) • Has you doctor ever said you have a heart condition? • Do you feel pain in your chest when you do physical activity? • Do you have chest pain when not doing activity? • Do you lose balance because of dizziness or do you every lose consciousness?

  5. ACSM Risk Stratification • Low Risk • Younger individuals (M<45, F<55) who are asymptomatic and meet no more than one risk factor threshold. • Moderate Risk • Older individuals (M≥45, F≥55) or those who meet the threshold for 2 or more risk factors. • High Risk • Individuals with one or more signs/symptoms of CV or pulmonary disease or with known disease

  6. Family History Cigarette smoking Hypertension Dyslipidemia Impaired fasting glucose Obesity Sedentary Lifestyle High HDL cholesterol CAD Risk Factors (Box 2-2)

  7. Signs/Symptoms Suggestive of CV & Pulmonary Disease • Pain, discomfort in the chest, neck, jaw, arms which may due to ischemia • Shortness of breath at rest or mild exertion • Dizziness or syncope • Ankle edema • Palpitations or tachycardia • Intermittent claudication • Unusual fatigue or shortness of breath with usual activities

  8. Cholesterol Sub-fractions Total Cholesterol = LDL-C + HDL-C + VLDL-C • Cholesterol Cut Points for Dyslipidemia • Total Cholesterol > 200 mg/dl • LDL-C >130 mg/dl • HDL-C < 40 mg/dl

  9. ACSM Recommendations for Medical Exam and Testing Prior to Exercise (Table 2-1)

  10. Informed Consent • Description and benefits of the assessment/program • Risks • Voluntary participation • Client informs of any problems they are having • Free to withdraw at any time
