Document Summary

Pa is any bodily movement produced by skeletal muscles that contributes to added energy expenditure beyond one"s resting energy expenditure/bmr. Important to measure pa to compare different groups, see trends over time, etc. ; document frequency and distribution of physical activity in defined population, dose-response for physical activity and health benefits, identify factors that influence physical activity behavior. Fit measuring: frequency, intensity, time/duration of exercise; mode of exercise, context. Objective tools: measurable and observable (fact based; heart rate monitor, accelerometer); Subjective tools: personal opinions, perspectives, feelings; strengths and weaknesses for all. Measurement tools: questionnaires, motion sensors, heart rate monitors, doubly-labeled water. Questionnaires/self report are the cheapest and most widely used measure; many available. Cons: recall bias/social desirability (lying, overestimating), large # of questionnaires available, Pros: ease of administration, low cost, record activity type and where performed not all questionnaires can be used to calculate energy expenditure (ee)
