Estimation of free-living energy expenditure by heart rate and movement sensing: a doubly-labelled water study.

Brage, Søren; Westgate, Kate; Franks, Paul W.; Stegle, Oliver; Wright, Antony; Ekelund, Ulf; Wareham, Nicholas J. (Journal article; Peer reviewed, 2015-09-08)

Background: Accurate assessment of energy expenditure (EE) is important for the study of energy balance and metabolic disorders. Combined heart rate (HR) and acceleration (ACC) sensing may increase precision of physical ...
Separating movement and gravity components in an acceleration signal and implications for the assessment of human daily physical activity

van Hees, Vincent T.; Gorzelniak, Lukas; Leon, Emmanuel Carlos Dean; Eder, Martin; Pias, Marcelo; Taherian, Salman; Ekelund, Ulf; Renström, Frida; Franks, Paul W.; Horsch, Alexander; Brage, Søren (Journal article; Peer reviewed, 2013-04-23)

Human body acceleration is often used as an indicator of daily physical activity in epidemiological research. Raw acceleration signals contain three basic components: movement, gravity, and noise. Separation of these becomes ...
