Measures of Physical Activity Using Cell Phones: Validation Using Criterion Methods
BACKGROUND Physical activity is associated with reduced risks of many chronic diseases. Data collected on physical activity in large epidemiological studies is often based on paper questionnaires. The validity of these questionnaires is debated, and more effective methods are needed. OBJECTIVE This study evaluates repeated measures of physical activity level (PAL) and the feasibility of using...
متن کاملAssessing physical activity using wearable monitors: measures of physical activity.
BACKGROUND Physical activity may be defined broadly as "all bodily actions produced by the contraction of skeletal muscle that increase energy expenditure above basal level." Physical activity is a complex construct that can be classified into major categories qualitatively, quantitatively, or contextually. The quantitative assessment of physical activity using wearable monitors is grounded in ...
