Term Description

An accelerometer is used to measure the intensity of movements continuously over a desirable study period (for a robust assessment of free-living physical activity, a minimum of 4 days is recommended; 7 days of continuous measurement is the most common). It is generally recommended to select the highest time resolution (or the shortest epoch) possible to last over the entire study period. Most current accelerometers have sufficient memory and battery capacity. The participant is asked to wear the accelerometer during all waking hours of the study period. Most monitors are not waterproof, and are not recommended for activities such as swimming and showering. An additional daily record of wearing the monitor can be taken to identify non-wearing time activity. Data are downloaded from the accelerometer after being retrieved from the participant. Although this is the current standard for objective physical activity measurements, more advanced sensor and processing technologies are rapidly evolving in this field to improve accuracy and expand usability. The hip placements of the accelerometer (on a belt) have been shown to yield the best prediction of energy expenditure. The absolute accuracy may vary with different accelerometers, placement locations, signal filters used by the devices, and models used for predicting energy expenditure or time spent in certain intensity categories. Follow manufacturers' operation manuals for installation, initialization, downloading and other specific procedures if needed.
