UNIT 2 PP6

• What are the subjective and objective methods of assessing physical activity and sedentary behaviour?

  Recall surveys, diaries, pedometry, accelerometry, inclinometry, observation tools, and personal activity trackers
• What is the purpose of assessing physical activity measurement?

  To inform health promotion efforts and understand relationships with health outcomes
• How can physical activity measurement be used in research?

  To understand the relationship between physical activity and health outcomes
• What are the measurable components of physical activity?

  Duration, frequency, intensity, type, and domains of activity
• What does the intensity of physical activity refer to?

  Classification of activities as light, moderate, or vigorous
• What are the domains or settings where physical activity can be performed?

  Leisure time, occupational, domestic, active commuting, incidental, and sedentary
• What are subjective measures of data collection in physical activity assessment?

  Measures requiring cognitive processing by participants to record their activity levels
• What are the two basic categories of self-report measures?

  Recall-based approaches and general measures
• What is the Global Physical Activity Questionnaire (CPAQ)?

  A self-report tool for assessing physical activity levels
• What are the advantages of self-report measures?

  Cheap, easy to use, and enables assessment of activity dimensions
• What are the disadvantages of self-report measures?

  Participants may over-report activity and have difficulty recalling information
• What are physical activity logs/diaries used for?

  To capture all sources and patterns of physical activity over a defined time frame
• What are the advantages of physical activity logs/diaries?

  Inexpensive and allows collection of data about specific activities
• What are the disadvantages of physical activity logs/diaries?

  Logging can be tedious and may cause behaviour modification
• Why are physical activity logs/diaries not suitable for young children or the elderly?

  Due to their cognitive and memory limitations
