Physical Activity & Sedentary Behaviour (Chapter 7)
What is the definition of sedentary behaviour?
Sitting or lying down with low energy expenditure
What does the acronym “FITT” stand for?
Frequency, Intensity, Time, Type
What does the acronym SEM stand for?
Socio-Ecological Model
Name one health-related fitness component.
Aerobic power, muscular strength, muscular endurance and flexibility
Name one reason to conduct a pre-fitness test.
Identify strengths/weaknesses, track progress, set goals
Name two examples of incidental physical activity.
Walking to the bus stop, taking the stairs, gardening
Is a pedometer an objective or subjective measure?
Objective
Give one example of a policy-level intervention to increase PA.
Educational Policies (e.g., PE uniform rules), Urban planning policies (e.g., bike paths or walking paths), workplace policies or Funding policies
Which component is tested by the sit-and-reach?
Flexibility
Which domain of PA includes organised sport and structured training?
Leisure-time domain
Name one advantage of using direct observation to measure PA.
Accurate, detailed context
What level of the SEM is a “walking group with friends”?
Social environment
Which two factors most affect anaerobic capacity?
Muscle fibre type & age
What is one individual factor that influences participation in physical activity?
Examples: age, gender, SES, motivation
Name one limitation of using a recall survey.
Relies on memory, prone to bias
Why might a school running a “Walk to School” day be considered a social environment level strategy?
Encourages peer/family participation and social support
Name the fitness component needed most for a
Muscular endurance
Explain the difference between moderate and vigorous intensity activity, including an example of each.
Moderate: increases HR slightly (e.g., brisk walking); Vigorous: greatly increases HR (e.g., running)
Describe the difference between subjective and objective PA measurement tools and give one example of each.
Subjective: based on personal report (e.g., diary); Objective: uses devices/observation (e.g., accelerometer)
Describe how the beep test or yo-yo test works and what it measures.
Increasing speed progressively via running, Aerobic power
Explain how validity and reliability are important in fitness testing.
Valid: measures what it’s meant to measure; Reliable: consistent results
