本研究的目的是检查选定的生理和心理反应，艰苦的实弹演习在不同配置的保护消防装备。职业消防员（n = 10）进行了三套消防演习的培训结构，包含两种不同配置的消防装备的实弹射击。在不同的日子里，受试者穿着：（a）NFPA 1500（1987）标准配置，和（B）臀部靴子配置的消防装备。在活动前和每次试验结束时记录生理和心理测量结果。重复测量方差分析显示，在1500档的表现时间比在臀部引导齿轮更大的强烈趋势。鼓膜温度存在显著的时间x档位相互作用，1500档位的温度更高。在1500档中，对努力和热感觉的感知也比在臀部靴配置的档中更大。两种档位配置之间认知功能测量的平均性能差异很小，但1500档位的性能变化较大。这些数据表明，在当前NFPA 1500标准配置中进行艰苦的消防演习会导致更长的执行时间，更大的热应变，以及更大的努力和热感觉。
The purpose of this study was to examine selected physiological and psychological responses to strenuous live-fire drills in different configurations of protective firefighting gear. Career firefighters (n = 10) performed three sets of firefighting drills in a training structure that contained live fires in two different configurations of firefighting gear. On separate days subjects wore: (a) the NFPA 1500 (1987) standard configuration, and (b) a hip-boot configuration of the firefighting gear. Physiological and psychological measurements were recorded pre-activity and at the end of each trial. Repeated measures ANOVA revealed a strong trend for performance time to be greater in the 1500 gear than in the hip-boot gear. There was a significant Time x Gear interaction for tympanic membrane temperature, with temperature being greater in the 1500 gear. Perceptions of effort and thermal sensations were also greater in the 1500 gear than in the hip-boot configuration of the gear. There was little difference in mean performance on cognitive function measures between the two gear configurations, but there was greater variability in performance in the 1500 gear. These data suggest that performing strenuous firefighting drills in the current NFPA 1500 standard configuration results in longer performance time, greater thermal strain, and greater perception of effort and thermal sensation.
