Exercise Pre-Participation Health Screening, Scope of Practice, and Clinical Biometrics

1. Foundations of Pre-Assessment

  • Purpose: Understand the client to ensure exercise testing is safe, valid, and tailored to their needs.

  • 4 Core Intake Questions:

    • Why is this person being tested?

    • Is testing safe, and how can risks be minimized?

    • What is the best communication style for this individual?

    • Which tests and physiological data are appropriate?

  • Inter-Tester Reliability: The level of agreement and consistency between different examiners administering the exact same assessment under standardized conditions.

2. Scope of Practice

  • Definition: The legal and ethical boundaries defining what a practitioner can and cannot do based on their credentials.

  • The 4 Pillars of Scope:

    • Formal academic education

    • Specialized professional training

    • Clinical and practical experience

    • Applicable regional and federal laws

  • CSEP-CPT Scope Boundaries:

    • Can work with apparently healthy individuals or those with a single stable health condition.

    • Cannot conduct maximal effort tests (aerobic or anaerobic).

    • Cannot interpret or use an ECG.

    • Cannot work with clients with unstable or multiple health conditions.

  • Criteria for a Stable Health Condition:

    • Diagnosed more than 6 months6\,\text{months} ago

    • Medically managed and asymptomatic

    • No changes in medication within the past 6 months6\,\text{months}

    • No modifications to the overall care plan within the past 6 months6\,\text{months}

3. Risks of Physical Activity

  • Primary Acute Cardiac Risks: Myocardial infarction (MI) and sudden cardiac death (SCD).

    • Under 30 to 40 years30\,\text{to } 40\,\text{years} of age: Events are usually caused by congenital or hereditary structural abnormalities.

    • Over 30 to 40 years30\,\text{to } 40\,\text{years} of age: Events are predominantly caused by coronary artery disease (CAD).

  • Risk Levels:

    • Absolute Risk: Extremely low (approximately 1 event per 2.9×106 sessions1\,\text{event per } 2.9 \times 10^6\,\text{sessions}
      ).

    • Relative Risk: High in sedentary individuals during unaccustomed vigorous exercise (up to 50×50\times
      higher than rest).

    • Protective Effect: Each additional day per week of habitual physical activity reduces relative cardiac risk by approximately 30%30\%
      .

  • Musculoskeletal (MSK) Injury:

    • Has a significantly higher absolute and relative risk than cardiac events.

    • Minimized by thorough warm-ups, progressing gradually, and coaching proper technique.

4. Health Screening and Clinical Measures

  • Pre-Participation Screening Goals: Identify known conditions, detect signs or symptoms of chronic disease, and decide if medical clearance is necessary.

  • Standard Screening Tools: PAR-Q+, Get Active Questionnaire (GAQ), APSS, and ACSM screening algorithms.

  • Critical Clinical Resting Cutoffs for Exercise Testing:

    • Resting Heart Rate (HR): >99 bpm> 99\,\text{bpm}
      requires holding testing.

    • Resting Blood Pressure (BP): >160/90 mm Hg> 160/90\,\text{mm\,Hg}
      requires holding testing for CPTs.

  • Key Signs and Symptoms of Chronic Disease (Red Flags):

    • Angina or chest, neck, or jaw discomfort

    • Dyspnea (shortness of breath) at rest or with mild exertion

    • Dizziness, lightheadedness, or syncope (fainting)

    • Orthopnea or paroxysmal nocturnal dyspnea

    • Bilateral ankle edema

    • Palpitations or resting tachycardia

    • Intermittent claudication (exertional lower leg cramping)

    • Known heart murmur or unexplained unusual fatigue
