S246 P01: Introduction to Exercise Programming and Assessment — Study Notes

Module Overview and Learning Outcomes

  • Describe the importance of pre-activity screening and medical clearance to determine potential risks and contraindications to exercise.

  • Demonstrate knowledge and skills in safely assessing the various parameters of fitness.

  • Recognize the need to obtain informed consent from participants prior to exercise or other procedures and demonstrate professional values and ethical conduct of a health practitioner.

  • Apply the ACSM’s guidelines to risk stratification in case scenarios.

  • Contraindications to exercise: presence of a medical condition where it is unsafe to exercise.

Module Synopsis

  • Students would apply theoretical evidence-based exercise science knowledge as rationale for technical skills of an exercise specialist.

  • Practice technical skills including real-time decision-making to ensure safe conduct of preparticipation screening, assessment, exercise prescription, and instruction of health-related fitness components (body composition, flexibility, cardiorespiratory fitness, muscular strength, muscular endurance) for the normal population.

  • Exposure to postural and balance assessment, use of industry-related tools and equipment, and ability to provide targeted interventions to health and performance goals.

Definitions, Health Trends, and Physical Activity (PA)

  • Definition of Physical Activity (WHO, 2020)

    • Leisure-time PA: Exercise

    • Planned, structured, repetitive and deliberate bodily movements intended to improve or maintain physical fitness (e.g., run, swim, cycle, kick boxing).

    • Physical Activity (PA): Bodily movement requiring energy expenditure.

    • Other Domains of PA: Occupation, Education, Household, Transportation (e.g., walk, climb stairs, housework, work).

  • Summary: PA includes a broad range of activities beyond leisure-time exercise; most health benefits accrue from total activity across domains.

National Population Health Trends (Singapore)

  • 2019 National Population Health Survey (Leisure-time Exercise):

    • Males: 38.7%

    • Females: 32%

  • Physically Inactive (No exercise during leisure): 40.2%

  • Occasional Exercise (At least 20 mins < 3x/week): 26.6%

  • Regular Exercise (At least 20 mins at least 3x/week): 35.2%

  • 2017/2020 trends

    • 2020: 2 in 5 overweight content

    • Obesity (ages 18-69): 8.7% (stable since 2013)

    • Overweight (adults): 36.2%

    • Overweight (children 6-18): 13% (11% in 2013)

    • Obesity rate projected to be 15% by 2024

  • Incidence of Chronic Diseases (as part of health risk discussion)

Health vs Physical Fitness: Concepts and Distinctions

  • Health (WHO, 1948): A state of complete physical, mental, and social well-being, not merely the absence of disease or infirmity. Includes physical, mental, emotional, social, and psychological aspects.

  • Physical Fitness: One’s ability to perform specific physical activities or tasks; specific to the individual and task; includes balance, flexibility, agility, speed, strength, power, endurance, etc.

  • Key question prompts: How are health and fitness related? Are they the same? Can a healthy person be unfit? Can a fit person be unhealthy?

Components of Fitness

  • Health-related components:

    • Cardiorespiratory (CV) endurance

    • Muscular endurance

    • Flexibility

    • Muscular strength

    • Body composition

  • Skill-related components:

    • Power

    • Agility

    • Balance

    • Coordination

    • Speed

    • Reaction Time

Differences: Health- vs Skill-Related Fitness

  • Health-related components promote optimum health, prevent disease and disability, and support daily functioning.

  • Skill-related components enhance performance in athletic events and motor skills.

  • Quote: “The five health-related components of physical fitness are more important to public health than are the components related to athletic ability.” — CDC

Objectives of Measuring Health-Related Fitness (Dwyer & Davis, 2008)

  • Educate

  • Individualized exercise program

  • Baseline and follow-up assessment

  • Motivation

  • Risk stratification

Professional Practice: Roles, Skills, and Ethics

  • Our job: Health & Fitness Professional

  • What Health & Fitness Professionals do:

    • Conduct client consultation and assessment

    • Facilitate goal setting

    • Educate client on exercise, health, and fitness

    • Prescribe exercise program

    • Instruct and demonstrate exercise

    • Evaluate and correct exercise technique

    • Maintain safety and confidentiality

  • What Health & Fitness Professionals don’t do (directly):

    • Diagnose medical conditions

    • Perform ACSM preparticipation & annual screen

    • Refer clients to medical practitioners when needed

    • Prescribe diets or provide treatment

    • Design accessory programs or use exercise to cure disease

    • Provide rehabilitation or post-rehabilitation exercise prescriptions

    • Provide counselling beyond coaching; provide general information as a coach

  • Adapted from Clark et al. (2008), NASM Essentials of Personal Fitness Training

Safety, Consent, and Legal Considerations

  • Safety: CPR-certified; check CPR certification validity; know how to use an AED.

  • Liability and risk management:

    • If not trained for a client with specific conditions, refer to a qualified specialist.

    • Exercise duty of care to the level of training.

    • If safety concerns arise, refer for medical clearance after preparticipation screening.

    • Waivers and releases can limit liability; professional indemnity insurance is increasingly common in Singapore.

  • Informed Consent

    • What is informed consent? A process to inform the client about the exercise or test procedure, benefits, risks, and alternatives. Client should be provided with a signed copy.

    • As professionals, conduct informed consent before testing or training. The client should understand that they are volunteering, have responsibilities (e.g., informing of problems), can withdraw at any time, and have the opportunity for a Q&A session.

Exercise Blood Pressure (BP): Measurement and Implications

  • Why measure HR and BP pre- and post-exercise?

    • Post-exercise hypotension: a transient drop in BP after exercise, may last ~10 minutes even at low intensity.

    • A passive recovery is used in emergencies or when clients cannot perform an active cool-down.

    • Rapid drops can lead to syncope; tachyarrhythmia may occur post-exercise.

  • BP measurement data and terminology

    • Blood pressure categories for adults (per slide/Table 3-1):

    • Normal: SBP < 120 ext{ mmHg} \text{ and } DBP < 80 ext{ mmHg}

    • Prehypertensive: 120≤SBP≤139extmmHg or 80≤DBP≤89extmmHg120 \le SBP \le 139 ext{ mmHg} \text{ or } 80 \le DBP \le 89 ext{ mmHg}

    • Stage 1 hypertension: SBP140−159extmmHg or DBP90−99extmmHgSBP 140-159 ext{ mmHg} \text{ or } DBP 90-99 ext{ mmHg}

    • Stage 2 hypertension: SBP≥160extmmHg or DBP≥100extmmHgSBP \ge 160 ext{ mmHg} \text{ or } DBP \ge 100 ext{ mmHg}

    • Initial therapy per the chart:

    • Normal and Prehypertensive: Lifestyle modification (no drug therapy unless compelling indications exist)

    • Stage 1 hypertension: Antihypertensive drug therapy indicated if compelling indications present; otherwise consider lifestyle modification and antihypertensives as indicated by risk factors

    • Stage 2 hypertension: Antihypertensive drug therapy indicated; two-drug combination for most

    • Compelling indications for drug therapy include: heart failure, prior myocardial infarction, high coronary heart disease risk, diabetes, chronic kidney disease, recurrent stroke prevention. For CKD or diabetes, BP goals often target <130/80 mm Hg.

    • Note: Combined therapy should be used cautiously in those at risk for orthostatic hypotension.

  • Controlled hypertension (definition and notes)

    • Defined as: average systolic BP < 140 mm Hg and average diastolic BP < 90 mm Hg over 2 readings in medicated individuals.

    • Controlled hypertension may appear as “normal” or “prehypertensive” under prior classifications when medicated.

    • Exercise preparticipation screening should be more cautious in seniors due to higher incidence of controlled hypertension.

  • Temporal relationship: SBP varies with age and exercise intensity

  • Practical takeaways for preparticipation screening

    • Understand HR and BP responses to exercise and during recovery to ensure safety.

    • Recognize post-exercise hypotension and the need for appropriate recovery strategy.

Practical Scenarios and Ethical Considerations

  • Preparticipation Screen and Medical Clearance

    • Use ACSM guidelines for risk stratification in case scenarios.

    • Decide when referral to medical practitioner is warranted based on screening results and risk factors.

  • Informed consent and autonomy

    • Ensure clients understand procedures, risks, benefits, and are free to withdraw at any time.

  • Documentation and confidentiality

    • Keep client information confidential; document consent and risk acknowledgments.

Recap: What You Should Take Away

  • Preparticipation screening and medical clearance are essential to identify contraindications and risks.

  • Health- and fitness-related concepts help structure safe, effective exercise programs.

  • Informed consent and ethical practice are foundational responsibilities of health & fitness professionals.

  • BP and HR monitoring before and after exercise provides critical safety data and informs progression and recovery strategies.

  • Understanding the distinction and link between health and fitness informs goal setting and intervention planning.

  • Liability, safety, and professional standards guide day-to-day practice and client interactions.
