Subjective or Objective
A survey where a person remembers and reports how active they were last week is this type of method.
subjective method
Define reactivity in the context of measuring physical activity.
Changing normal behaviour because you are being measured
Name one method of measuring the intensity of physical activity
Heart rate, RPE or talk test
Name the four levels of the social-ecological model.
Individual, social environment, physical environment, policy
Which app is famous for short videos and dance trends
TikTok
Pedometers and accelerometers belong to this type of method because they measure movement directly.
objective method
one disadvantage of using a recall survey to measure physical activity
People forget or exaggerate, so data is less accurate
Describe how the talk test can be used to judge exercise intensity
Can talk but not sing = moderate. Only a few words = vigorous.
Maya is a 9-year-old girl who lacks confidence in sport. Identify the level of the social-ecological model this barrier belongs to
Individual
What are the school house colours?
Green, White, Blue, Red
In this objective method, a trained person watches a group and records the activity they see.
direct observation
one advantage of using subjective methods to measure the physical activity of a large population.
Cheap, quick and easy to give to many people
Explain how heart rate can be used to measure exercise intensity.
Heart rate rises with intensity. Compare it to % of maximum heart rate.
Maya's parents work late and have no time to take her to sport. Identify the level of the model and explain how this affects her participation
Social environment. No family support or transport, so she can't attend.
What colour do you get by mixing blue and yellow?
Green
Smartwatches, fitness bands and phone apps are all grouped as this kind of objective method.
wearable and digital tools
A teacher uses pedometers to measure Year 9 students' activity during sport. Explain how reactivity could affect the data collected.
Students move more because they know they're measured, so data overestimates usual activity
Justify the use of a recall survey to measure the activity levels of a whole school of 800 students
Cheap, quick, many students at once, no equipment needed
Maya lives in an area with no safe parks or footpaths. Identify the level of the model and explain how this is a barrier to her activity.
Physical environment. No safe places to be active.
What is Mr Taylor's favourite drink?
Coffee
Sort these four methods into subjective and objective: diary, pedometer, recall survey, direct observation.
Subjective: diary and recall survey. Objective: pedometer and direct observation.
Compare the effectiveness of pedometers and direct observation for measuring physical activity in a school.
Pedometer: cheap, objective, steps only. Observation: shows intensity and context, but time-consuming and only small groups.
Give an example of a policy that could act as an ENABLER to physical activity.
Mandated PE minutes in schools, active working incentives, urban planning (bike lanes etc)
