This often contributes to significant heat and cardiovascular strain. This study examined the relationships between psychological and physical measures taken prior to undertaking a 15 min firefighting task, and the occurrence of heat stress and high levels of fatigue following the task. Nine qualified firefighters completed a 15 min \u201clive burn\u201d scenario designed to mimic a fire started by a two-seater couch in a lounge room and completed simulated tasks throughout the duration. Logical reasoning, speed and accuracy, general motivation and fatigue, and physical and mental effort were recorded pre-scenario, and at 0- and 20-min post-scenario. General motivation and fatigue scores at 0- and 20-min post-scenario were highly correlated with each other (rs = 0.90; p = 0.001). The general motivation and fatigue scores, at 0- and 20-min post-scenario, were also strongly related to pre-task logic\/reasoning test scores (Post 0 rs = \u22120.77, p = 0.016; Post 20 rs = \u22120.87, p = 0.002). Firefighters with lower logical reasoning and speed and accuracy scores were more susceptible to fatigue and impaired cognition when exposed to rises in core temperature and heat stress.<\/jats:p>","DOI":"10.3390\/biology11010104","type":"journal-article","created":{"date-parts":[[2022,1,10]],"date-time":"2022-01-10T17:42:25Z","timestamp":1641836545000},"page":"104","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":20,"title":["Psychological, Physical, and Heat Stress Indicators Prior to and after a 15-Minute Structural Firefighting Task"],"prefix":"10.3390","volume":"11","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8358-398X","authenticated-orcid":false,"given":"Elisa F.
