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.
