Study Notes

Definitions and Key Terms

  • Habitual physical activity: Bodily movement increasing energy expenditure, produced by skeletal muscles.
  • Exercise: Planned, structured physical exertion aimed at improving health, not competitive (e.g., jogging).
  • Sport: Physical activity with set rules and goals, often competitive (e.g., swimming, rugby).
  • Physical fitness: Health state allowing performance in sports, daily activities; attained through proper nutrition, exercise, and rest.
  • Hypokinetic disease: Disease caused by physical inactivity.

Hypokinetic Diseases Overview

  • Coronary Heart Disease (CHD): Major heart condition resulting from narrowed arteries.
  • Stroke: Disruption of blood flow to the brain.
  • Hypertension: Chronic high blood pressure (≥140/90 mmHg), can lead to serious cardiovascular issues.
  • Obesity: Excessive body fat, linked to various health conditions.
  • Type 2 Diabetes: Insulin resistance often tied to lifestyle choices.
  • Osteoporosis: Weak and brittle bones, increasing fracture risk.
  • Inactivity levels rise with increasing Gross National Product (GNP), indicating a shift to sedentary lifestyles.
  • Urbanization contributes to decreased physical activity due to environmental changes (e.g., fewer parks).
  • Aging populations show higher risks of hypokinetic diseases alongside reduced physical activity.

Societal Changes and Hypokinetic Diseases

  • Movement from farming to urban living has led to more sedentary lifestyles.
  • Technology has reduced physical labor demands, increasing prevalence of diseases like cancer, diabetes, and obesity.
  • Modern work expectations limit opportunities for physical activities, while availability of fast food promotes poor dietary habits.

Coronary Circulation

  • Blood flow to coronary arteries is restricted during heart contractions and resumes during relaxation.
  • Right and left coronary arteries branch from the aorta to supply oxygenated blood to the heart.
  • Blood travels through coronary arteries, capillaries for nutrient delivery, then returns via veins.

Atherosclerosis

  • Affects arteries via accumulation of fat and cholesterol, narrowing them.
  • Can cause blood flow issues, leading to clots, contributing to CHD and strokes.

Major Risk Factors for Cardiovascular Disease

  • Cigarette smoking, hypertension, high levels of LDL cholesterol, low HDL cholesterol, diabetes, and obesity.
  • Other factors include age, gender, ethnicity, and family history.

Understanding Cardiovascular Risk Factors

  • Risk factors categorized as modifiable (e.g., obesity) and non-modifiable (e.g., age).
  • Impacts are cumulative; multiple factors increase overall risk.

Physical Inactivity and Cardiovascular Risk

  • Sedentary lifestyles heighten the risk of cardiovascular disease and associated conditions.
  • Encouragement to balance sedentary activities with physical exercise is crucial for health.

Obesity Determination

  • Identified by excess body fat, assessed through BMI and waist circumference, which reflect health risks.

Health Consequences of Obesity

  • Leads to cardiovascular problems like CHD, hypertension, type 2 diabetes, and osteoarthritis.
  • Also linked to reduced lung capacity and increased risk of certain cancers.

Energy Balance Concept

  • Energy balance is crucial for weight control, defined by the relationship between caloric intake and energy expenditure.
  • Positive energy balance leads to weight gain, while negative balance results in weight loss.

Appetite Regulation

  • Gut hormones like leptin and ghrelin affect feelings of hunger and satiety by acting on the brain's appetite center.

Type 1 vs. Type 2 Diabetes

  • Type 1: Insulin-dependent, primarily in youth, rapid onset, treated with insulin.
  • Type 2: Non-insulin dependent, associated with obesity and older age, managed with lifestyle changes.

Risk Factors for Type 2 Diabetes

  • Linked to obesity, high-fat diets, physical inactivity, and family history.
  • Higher prevalence seen in certain ethnic groups.

Health Risks of Diabetes

  • Complications can include vision loss, kidney disease, nerve damage, and cardiovascular issues.

Bone Density Changes

  • Increases from birth until 35-45 years, followed by a decline, especially in females post-menopause.

Osteoporosis Risks

  • Women face higher risks due to lower density and rapid aging effects, influenced by estrogen levels and lifestyle choices.

Long-Term Effects of Osteoporotic Fractures

  • Result in loss of independence, physical complications, and financial burdens.

Osteoporosis Risk Factors

  • Include lack of calcium, smoking, alcohol consumption, inactivity, and low body weight.

Physical Activity and Bone Health

  • Weight-bearing exercise is vital for maintaining bone health, but overly intense training may cause adverse effects in some athletes.

Physical Activity Guidelines

  • WHO recommends 150 minutes of moderate or 75 minutes of vigorous aerobic activity weekly, plus muscle-strengthening exercises twice a week.

Exercise in Hypokinetic Disease Management

  • Aims to maximize function, relieve symptoms, and reduce medication reliance.

Barriers to Physical Activity

  • Can include uncontrolled disease states, injury risks, and individual health issues.

Mood and Exercise

  • Exercises effectively alleviate mood disorders, enhancing feelings of well-being and reducing anxiety and depression symptoms.

Exercise Adherence Strategies

  • Incorporate environmental, reinforcement, goal-setting, and social support approaches to encourage regular activity.

Non-communicable vs. Communicable Diseases

  • Non-communicable: Long-duration diseases not transmitted person-to-person (e.g., cardiovascular diseases).
  • Communicable: Caused by infectious agents and easily transmitted (e.g., pneumonia).

Population Attributable Risk (PAR)

  • Measures the public health burden attributable to specific risk factors, indicating potential health improvement if these factors are eliminated.### Population Attributable Risk (PAR)
  • PAR for lung cancer deaths linked to moderate smoking is 52%, indicating that over half of these deaths could be avoided without smoking.
  • PAR calculations help prioritize public health initiatives by demonstrating the impact of risk factors on health outcomes.
  • Assumes a causal link between risk factors and health issues, guiding health policies and preventive measures.

Relationship Between Moderate Exercise and Health

  • Walking is associated with a reduced risk of mortality, coronary heart disease (CHD), cardiovascular disease (CVD), and type 2 diabetes.
  • Benefits of moderate exercise include:
    • Improved metabolic rates and VO2max
    • Increased energy expenditure
    • Better plasma lipid profiles
    • Lower body fat percentage
    • Reduced blood pressure
    • Decreased likelihood of skeletal injuries

Causes of Sudden Cardiac Death (SCD) in Athletes

  • SCD is influenced by:
    • Underlying medical conditions, such as genetic disorders like hypertrophic cardiomyopathy (HCM)
    • Exercise intensity
    • Frequency of habitual weekly exercise

Definition of Musculoskeletal Injuries

  • Musculoskeletal injuries encompass disorders related to muscles, bones, tendons, blood vessels, nerves, and soft tissues.
  • Common injuries include sprains, strains, and inflammatory conditions.

Types of Injuries: Compression, Tension, and Shearing

  • Compression Injuries: Result from a compact impact that causes bruising, bleeding, or fractures, often from player collisions.
  • Tension Injuries: Occur when tissues are overstretched, evident during landings (e.g., after a jump).
  • Shearing Injuries: Result from friction between surfaces, impacting skin and connective tissues (e.g., skin against the ground).

Acute vs. Chronic Injuries

  • Acute Injuries: Occur suddenly due to specific incidents, e.g., fractures, ligament tears, concussions.
  • Chronic Injuries: Develop gradually, typically due to repetitive activities, e.g., tennis elbow, shin splints.
  • Lower limb injuries account for the majority, particularly in football, running, and skiing.
  • Common lower limb injuries include meniscus tears and ligament sprains.
  • Spinal injuries, such as fractures, commonly occur in sports like diving and gymnastics.
  • Head injuries, including concussions, are prevalent in cycling and rugby.
  • Major contributors include repetitive stress and impact from running.
  • Additional factors influencing injury risk:
    • Rapid increases in training distance or intensity
    • Running surface types
    • Appropriate footwear
    • Previous injuries and overall running experience
    • Biomechanical imbalances and sudden directional changes

Risk and Hazard Reduction in Exercise

  • Effective prevention strategies are tailored to the sport and individual athletes, and may involve:
    • Engaging in consistent moderate exercise
    • Utilizing protective gear
    • Undergoing regular health evaluations
    • Implementing injury prevention techniques like proper warm-ups and cool-downs
    • Educating coaches, referees, and athletes on injury prevention

Evaluating Benefits and Hazards of Exercise

  • Strenuous exercise might carry risks, but its benefits often outweigh these risks.
  • Regular moderate to vigorous exercise is linked to protection against CHD.
  • Risks associated with specific exercises like jogging, walking, and cycling include injuries from vehicle collisions and falls.
