TLDR
These data provide a template on which patterns of activity can be classified into intensity levels using the CSA accelerometer, and help to predict energy expenditure at any treadmill speed.Abstract:
Purpose:We established accelerometer count ranges for the Computer Science and Applications, Inc. (CSA) activity monitor corresponding to commonly employed MET categories.Methods:Data were obtained from 50 adults (25 males, 25 females) during treadmill exercise at three different speeds (4.8read more

TL;DR: Objective and subjective measures of physical activity give qualitatively similar results regarding gender and age patterns of activity, however, adherence to physical activity recommendations according to accelerometer-measured activity is substantially lower than according to self-report.

TL;DR: In the present review, self-reports are defined as selfadministered or interviewer-administered recall questionnaires, activity logs or diaries, and proxy reports (typically used to assess young children).

Conducting accelerometer-based activity assessments in field-based research.
TL;DR: Accelerometer-based activity assessments requires careful planning and the use of appropriate strategies to increase compliance, and face-to-face distribution and collection of accelerometers is probably the best option in field-based research, but deliveries by express carrier or registered mail is a viable option.

Neighborhood-Based Differences in Physical Activity: An Environment Scale Evaluation
TL;DR: Neighborhood environment was associated with physical activity and overweight prevalence and the reliability and validity of self-reported neighborhood environment subscales were supported.

A method to assess energy expenditure in children and adults.
TL;DR: It is concluded that the 3-day activity record is a procedure suitable to estimate energy expenditure in population studies and supports the hypothesis that mean energy expenditure per kg of body weight is significantly correlated with physical working capacity expressed per kgof body weight.

Validity of the Computer Science and Applications, Inc. (CSA) activity monitor.
TL;DR: It is concluded that the CSA and Caltrac accelerometers have similar validity and that either instrument can be used to estimate EE of groups.

The stability of children's physical activity as measured by accelerometry and self-report
TL;DR: Data indicate that in field settings: 1) accelerometry can be used to assess the intensity of children's activity and 2) 4 or more days of activity monitoring are needed to achieve satisfactory reliability.

The Caltrac accelerometer as a physical activity monitor for school-age children.
TL;DR: Data support the use of the Caltrac accelerometer as a physical activity measure for school-age children, and the objective data tended to corroborate the children's short-term activity recalls.
