Association between metabolic syndrome and physical fitness in firefighters: a protocol for a systematic review and...

Among the emergency services, firefighters have the highest percentage of mortality (45%) due to sudden cardiac death, with the majority related to underlying cardiovascular disease. This necessitates that firefighters stay in good physical condition and maintain adequate cardiovascular fitness to cope with these stressors and perform their duties with minimal health risks. Therefore, this study aims to determine the association between metabolic syndrome and physical fitness in firefighters.

The authors will search the following electronic databases: PubMed/Medline, SCOPUS and Web of Science, with no limitations to publication year. For data extraction, the two principal reviewers will use a general data extraction form to retrieve the key characteristics of each study. The Rayyan intelligent systematic review tool will be used to screen and select studies for inclusion. Thereafter, information from the included studies will be captured on the researcher-generated data extraction form. The Joanna Briggs Institute (JBI) Critical Appraisal Tools for quantitative studies will be used to conduct the methodological assessment of each study included. Data will be analysed using Review Manager 5.3 to determine the exposure effects and MedCalc statistical software Ltd and will be used to determine the pooled correlation effects. The results will be presented using figures, graphs and tables.

Details for this systematic review protocol can be accessed on PROSPERO (CRD42024535088). The authors will disseminate this protocol and the findings of the systematic review and meta-analysis in peer-reviewed journals and in national and international conferences. In addition, this review will add significantly to the body of knowledge in the scientific community worldwide and assist academics in exploring research gaps on this topic.
