Abstract

During military operations, soldiers often encounter extreme environmental, metabolic and neuropsychiatric conditions, which combined lead to a fatigue status that can cause serious physiological impairments, decreasing military performance on the battlefield. Comprehensive studies in realistically stressful environments are essential to expand the knowledge regarding the consequences of real-life stress exposure, facilitate development of operationally-useful techniques and promote the conception of improved treatments. Therefore, a systematic review is proposed to obtain relevant information about fatigue assessment through multiple physiological parameters in the military context, to focus on determining the associations between fatigue and physiological response in order to plan in the future adequate interventions to prevent related negative consequences. Thus, following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Protocols (PRISMA-P) Statement, this systematic review protocol was elaborated in order to present adequate guidelines to develop a research that can provide appropriate results to fulfil the sought objective. Five databases will be accessed (SCOPUS, PubMed, Science Direct, Medline and Web of Science) and a total of 9 combinations of keywords will be used. This protocol is registered in PROSPERO under the code of PROSPERO CRD42018105833.

Highlights

  • A systematic review is proposed in order to search for relevant information about fatigue assessment through multiple non-invasive physiological parameters in the military context, to focus on determining the associations between fatigue and physiological response in order to plan in the future adequate interventions to prevent related negative consequences

  • - The first objective is to identify fatigue assessment methods performed during military operational scenarios and that involve measurement of multiple physiological parameters, with focus on non-invasive procedures, to determine the associations between fatigue and physiological response that could lead to planning future adequate interventions

  • This systematic review protocol follows the guidelines outlined in the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Protocols (PRISMA-P) Statement (Shamseer et al 2015, Moher et al 2015). 2.2

Summary

Background

Fatigue is a complex and multifaceted phenomenon. One of its most common definitions states it as a “failure to maintain the required or expected force” (Edwars 1983). Soldiers, are exposed to extreme environments, heavy workload, inadequate sleep, information overload, dehydration and impaired nutritional status The combination of these stressors can cause serious physiological impairments, decreasing physical and military performance on the battlefield (Henning, Park, and Kim 2011, Lieberman et al 2005). Collecting the necessary physiological data in mission environments and activities has historically been hindered by lack of access to in-theatre warfighters and difficulties associated with measuring parameters such as heart rate and core temperature in the field It is only with the development of non-invasive physiological status monitoring systems, that such data can be collected effectively during military activities. A systematic review is proposed in order to search for relevant information about fatigue assessment through multiple non-invasive physiological parameters in the military context, to focus on determining the associations between fatigue and physiological response in order to plan in the future adequate interventions to prevent related negative consequences
