    Study Notes

    Physical Activity and Exercise Concepts

    • Physical Activity: Any movement by skeletal muscles that requires energy.
    • Exercise: Planned, structured, and repetitive movement aiming to improve or maintain physical fitness.
    • Physical Fitness: Set of attributes that enable the body to handle physical demands without excessive fatigue.

    Importance of Physical Activity

    • Provides numerous health benefits.
    • Aids in weight management.
    • Enhances physical fitness levels.
    • Improves overall quality of life.
    • Increases body control and energy.

    Recommendations for Physical Activity

    • Minimum of 30 minutes of moderate-intensity aerobic activity on 5 days a week or 20 minutes of vigorous-intensity on 3 days a week.
    • Tailor activity goals based on current fitness level, health status, and objectives.
    • Raise activity levels for weight management concerns.
    • Seek opportunities for activity throughout the day.
    • Comprised of Cardiovascular Endurance, Muscular Strength, Muscular Endurance, Flexibility, and Body Composition.

    Cardiovascular Endurance

    • Defined as the ability to perform dynamic exercise at moderate to high intensity for extended periods.
    • Improved functions include a stronger heart, slower resting heart rate, increased blood volume, better tissue blood supply, enhanced bodily control, and decreased resting blood pressure.
    • Activities to enhance endurance include walking, jogging, cycling, and aerobic dancing.

    Muscular Strength

    • Measured by lifting a set weight and comparing results to established norms.
    • Consistent muscle training leads to strength gains.
    • Any rigorous activity that strains muscles until fatigued promotes strength improvement.

    Muscular Endurance

    • Ability of muscles to exert force continuously without tiring.
    • Strength training focuses on size, while endurance training emphasizes cardiovascular efficiency and oxygen delivery.
    • Involves different muscle fibers:
      • Fast Twitch Fibers: Contract quickly, tire quickly, useful in sprints.
      • Slow Twitch Fibers: Better suited for endurance, less fatigue, rely on oxygenated blood.

    Flexibility

    • Describes the range of motion around a joint.
    • Enhances smooth movement coordination and injury prevention.
    • Specific to individual joints and influenced by ligament and tendon tightness.
    • Can be improved through various stretching activities, which can be categorized into three common types.
