Why Measure Physical Activity?
Identify factors that influence physical activity levels (determinants)
Monitor how many people are achieving national guidelines
Identify population trends
Evaluate the effectiveness of large-scale interventions
Determine the amount of physical activity necessary to influence health
Detect change in an individual’s health and/or behavior
Determine the effect of any change in physical activity behavior
Measuring Physical Activity
Physical activity levels can be measured using various methods, both subjective and
objective.
Many things need to be considered before picking a method appropriate to individual or
group.
The data collected can then be used to gauge whether or not an individual or group of
individuals adheres to guidelines among other things.
Domains & Context of Physical Activity
Physical activity occurs in different places; domains
Four commonly recognized domains:
oOccupational/school
oLeisure-time
oHousehold, gardening
oActive transport

Document Summary
Identify factors that influence physical activity levels (determinants) Monitor how many people are achieving national guidelines. Determine the amount of physical activity necessary to influence health. Detect change in an individual"s health and/or behavior. Determine the effect of any change in physical activity behavior. Physical activity levels can be measured using various methods, both subjective and objective. Many things need to be considered before picking a method appropriate to individual or group. The data collected can then be used to gauge whether or not an individual or group of individuals adheres to guidelines among other things. Four commonly recognized domains: occupational/school, leisure-time, household, gardening, active transport. Duration: length of session or accrued length of physical activity during a week. Intensity: amount of effort required for the activity low (slow walking), moderate (brisk walking), vigorous (jogging) Type: other information about the nature of the activity and its purposes (e. g. , strength) Subjective measures rely on the opinions of the subject.
