Document Summary
Precise measurement evaluate effectiveness of interventions, make cross cultural comparisons and better monitor temporal trends in pa behaviour. Intensity + frequency + duration = total volume of pa. Document frequency and distribution of physical activity in defined population. Dose-response for physical activity and health benefits. Physical activity complex in nature is used to measure pa. Categorize tools as subject or objective and highlight strengths and weaknesses. Questionnaires: physical activity questionnaire-children (paq-c, pros, ease of administration, record activity type and where performed. Low cost: cons, recall bias/social desirability, not all questionnaires can be used to calculate ee. Digital recording of the intensity of movement produced during activity. Sensor picks up the amplitude and frequency of movement produces an electrical current of various magnitude (more intense the movement the greater the voltage) Stores the information as activity counts converted to aee/mets based on default or predetermined cut points. Pros: evaluates frequency, intensity, and duration, non burdensome.
