Physiological variables in energy expenditure estimation by actigraphy: a systematic review protocol

Abstract

Background: Energy expenditure measurement based on movement quantity is showed as a relevant alternative in clinical and research contexts. The best recommended and validated methods are expensive and inconvenient to field measurement, limiting the use to the laboratory. Lately, several devices have been developed to identify and classify activities by body movements, showing acceptable outcomes. These devices and techniques have been used to estimate energy expenditure in many physical activities situations. However, for this, is necessary include physiological variables. Methods: We propose a systematic review to identify evidence of influence and relevancy of physiological variables in energy expenditure measurement by actigraphy. We will search for Academic Search Complete, Scopus, Web of Science, Science Direct, Pubmed, and Informaworld by Francis & Taylor databases. Discussion: The outcomes will be synthesized to identify variables used in energy expenditure calculation methods and analyze the error between measured and calculated values considering the influence of physiological variables on this.

Modeling Energy Expenditure Estimation in Occupational Context by Actigraphy: A Multi Regression Mixed-Effects Model

“…Various studies associated with energy expenditure have been conducted within different contexts. From the occupational perspective, it has also been proven to be of great utility for improving workers’ ergonomics, safety, and health [ 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9 ].…”

“…The most accurate measurement methods considered are the double-labeled water method and direct and indirect calorimetry by oxygen consumption rate [ 2 , 10 ]. Alternatively, as direct measurements are complex, expensive, and unsuitable for field studies, several models have been adopted as a significant technique for assessing energy requirements [ 11 ].…”

“…Alternatively, as direct measurements are complex, expensive, and unsuitable for field studies, several models have been adopted as a significant technique for assessing energy requirements [ 11 ]. Most of them, developed by regression methods, combine anthropometrics, physiological variables, and movement patterns and are accepted for predicting energy requirements over a wide variety of activities [ 2 , 12 , 13 ].…”

3rd Symposium on Occupational Safety and Health Proceedings Book

“…Various studies associated with energy expenditure have been conducted within different contexts. From the occupational perspective, it has also been proven of great utility for ergonomics, safety, and health of workers (Lucena, Guedes, Vaz, & Silva, 2018). Specifically, resting energy expenditure (REE) contributes to 60-70% of daily energy requirements.…”

“…REE can be measured through indirect calorimetry or estimated using predictive equations. The gold standard to determine the REE is the measurement by indirect calorimetry (ISO, 2004;Lucena et al, 2018). However, procedures for direct measurements are complex, expensive and not feasible for frequent and timely individual use (Sabounchi, Rahmandad, & Ammerman, 2013;ten Haaf & Weijs, 2014).…”
