NPAG Scenarios Answers Answers

Subjective and Objective ways to Measure Physical Activity Why measure our levels of activity? - Document how active our population is. - Gives feedback on government health programs - An active nation is a healthy nation - Study the factors that influence our participation

Ways we can Measure Activity - Think about all the different ways we can measure activity. - Not just specific and accurate but also inaccurate and easy.

Methods of Measuring Physical Activity Measurement is defined as both: Subjective and Objective. Subjective = Not 100% factual Objective = Factual

Objective Measuring Devices Any Familiar

Objective Measures: Direct Observation Direct Observation – Involves watching people and noting specific behaviours and activities they are participating in. Commonly used on children while playing. Advantages Quantitative and qualitative information Behaviour observed Wider variety of information gained Software available Used in school and community settings Disadvantages Difficult with large populations Obtrusive and time consuming Can cause bias

Objective Measures HR Monitors HR monitors measure our hearts response to exercise intensity and energy expenditure. HR is very useful in the laboratory and in sports training. Is unobtrusive and gives quick data collection. However, HR is not influenced by intensity alone. There is also a lag between HR change and intensity.

Measurement Options – HR monitors Advantages Disadvantages

Measurement Options - Pedometers Advantages Disadvantages

Accelerometers Advantages An expensive device used to measure intensity of movement of the subject over a period of time. Measured in units of acceleration

Subjective Measures Examples of subjective (remembering physical activity done) are self-reported recall measures, diaries and logs. Eg. Active Australia Survey IPAQ. Examples of subjective (remembering physical activity done) are self-reported recall measures, diaries and logs. Eg. Active Australia Survey IPAQ. StrengthsWeaknesses Assess multiple domains Can be quickly administered to large groups Low reliability and validity Social biases in answers given Poor recall skills in children
