Effect of cooling vests on physiological and perceptual responses: A systematic review protocol

Abstract Background: Human in hot environments are exposed to several risks and discomforts which seriously affect their physiological and mental workload. However, they are required to take frequent rest breaks to prevent heat strain when working in hot environments. The main objective of this study is to systematically summarize the literature about the effect of cooling vests on physiological and perceptual responses that might help research and practice in the future.Inclusion criteria: Studies in scientific journals and other databases, focusing on the effect of cooling vests on physiological and perceptual responses will be included. Methods: Three main databases such as PubMed, Scopus, and Web of Science will be searched to find relevant literature on type of cooling vest and effects using subject headings and appropriate MeSH terms. Inclusion and exclusion criteria will be used for screening. Two authors will participate in all of the search stages including preliminary search, screening, quality assessment, data extraction, and data synthesis. We will limit our search to articles published in a peer review journal between 2000 and 2019. The protocol has been written according to PRISMA-P checklist.
