Physical Activity
Self-Report
Self-report measures of physical activity include questionnaires, activity logs, and diaries. These measures are the most frequently used method of assessing physical activity levels among free-living individuals. These tools vary in their ability to quantify the frequency, intensity, type, and duration of various occupational, sports and leisure, transportation, and household activities over a variety of time frames.

Objective Measures
Objective measures of physical activity include measures of energy expenditure such as doubly-labeled water, movement monitors such as pedometers and accelerometers, and measures of the physiological responses to physical activity including heart rate monitoring and fitness testing.

Sedentary Behavior
Self-Report
Sedentary behavior is often defined as sitting or lying with very low energy expenditure. Sedentary behavior has a negative impact on health which may be independent of time spent in moderate-to-vigorous activity. Various methods are available to quantify sitting time, screen time, and other sedentary behaviors. These methods include self-report surveys, self-report diaries, and checklists.

Objective Measures
Sedentary behavior is often defined as sitting or lying with very low energy expenditure. Sedentary behavior has a negative impact on health which may be independent of time spent in moderate-to-vigorous activity. Direct measures of sedentary behavior include accelerometers, inclinometers, and direct observation techniques. These tools vary in their ability to quantify time spent sitting or physically inactive as well as body posture.

Physical Function
Self-Report
Self-report measures of physical function usually come in the form of a questionnaire and assess information concerning an individual’s perception of their ability of completing a specific task. These measures are the most commonly used method to assess function. In addition, these measures vary by time frame, are often easy to administer, and are relatively inexpensive. However, these measures are less likely to identify slight functional limitations compared to performance based measures

Performance-Based
Performance-based measures of physical function examine an individual’s actual performance for completing a task. These measures include measures of mobility, gait, balance, grip, reach, and manual dexterity. Performance-based measures have face validity, are sensitive to change, and have been shown to be more highly associated with markers of health than self-report measures.
