Estimation of energy expenditure using CSA accelerometers at hip and wrist sites

Article Abstract:

This article examines the accuracy of using hip and wrist accelerometers to measure the energy costs of housework, yardwork, and recreational activities. Results indicate that adding the data from the wrist accelerometer to hip measurements resulted in minimal improvements in accuracy that were offset by the additional equipment costs.

Evaluation of heart rate as a method for assessing moderate intensity physical activity

Article Abstract:

This article examines the validity of using heart rate measures taken during moderately vigorous exercise to estimate energy metabolism. Results indicate that heart rate measures were correlated with oxygen consumption levels and provided accurate, objective, and noninvasive estimates of energy expenditure.

Quantifying energy expenditure and physical activity in the context of dose-response

Article Abstract:

This article examines methods used to assess physical activity and energy expenditure in research investigating dose-response relationships between exercise and health. There is significant variability in the accuracy of methods used to quantify physical activity and energy expenditure which limits the interpretation of research on dose-response relationships.
