Study Notes

Lifestyle Physical Activity

  • Lifestyle physical activity is activity performed for a task outcome, including ADLs, occupational activity, and physical transportation.
  • A person with a physically demanding job may be more active compared to someone with a desk job who exercises for an hour daily.

What Factors Affect Lifestyle PA?

  • Factors affecting lifestyle physical activity (PA) include PHAWG (not further defined in the provided text).

Leisure Time Physical Activity

  • Leisure-time physical activity involves activity performed for the activity itself, instead of a task.

Exercise

  • Exercise is planned, structured, and repetitive activity designed to improve or maintain fitness, performance, or health.
  • Includes variables such as frequency, intensity, duration, and mode.

Components of Fitness

  • Cardiovascular fitness (VO2 max)
  • Muscular strength (maximal force)
  • Muscular endurance (repeated submaximal force)
  • Body composition (body fat percentage)
  • Flexibility (range of motion)

Classifications of Physical Activity

  • Classifications include lifestyle activity, physical activity, leisure time activity, exercise, sports/hobbies, occupational activity, and ADLs.

Defining Sedentary Behavior

  • Sedentary behavior involves activities with minimal energy expenditure above resting levels.
  • Examples include watching TV, using computers, or sitting at a desk.
  • Sedentary behavior is associated with negative health effects, even independent of physical activity levels.

What Happens When You Sit?

  • Caloric demand decreases shortly after sitting.
  • After an hour, fat oxidation and insulin sensitivity also decrease.
  • Prolonged sedentary time increases the risk of abnormal glucose and lipid metabolism, type 2 diabetes, and mortality.

Physical Activity Intensity

  • MET levels are used to describe activity intensity: Light (<3.0 METs), Moderate (3.0-6.0 METs), and Vigorous (>6.0 METs). This is related to oxygen consumption.
  • Examples of activities at different MET levels are provided.

Physical Fitness

  • Physical fitness is the ability to complete physical tasks or activities without undue stress or fatigue.
  • Physical fitness has health-related components like cardiorespiratory endurance, body composition, muscular strength & endurance, and flexibility.
  • Physical fitness also has skill-related components such as agility, balance, coordination, power, and speed.

Relationship of PA, Fitness, and Health

  • Physical activity improves fitness which in turn improves health.
  • The intensity of the activity can affect cardiovascular fitness, potentially reducing risk of mortality.
  • Relationships are represented in several graphs showing various activity levels and their respective health effects.
