Purpose: This study aims to assess the physical cognition according to changes in the weight of firefighting Self Contained Breathing Apparatus (SCBA), and to provide foundational data for establishing standards for firefighting SCBA based on these results. Method: The study investigated and analyzed changes in physical changes, Rating of Perceived Exertion (RPE), and cognitive factors among firefighters and non-firefighters wearing three different types of SCBA with varying weights, following appropriate exercise loads. Result: In the case of the firefighter group, wearing SCBA with varying weights during exercise did not show significant differences in respiratory rate, heart rate, and blood pressure. Similarly, in the non-firefighter group, differences in weight change were not significant. Additionally, both groups did not demonstrate differences in RPE based on SCBA weight changes, and participants did not cognize changes in SCBA weight during the experiment. Conclusion: Due to the low level of physical cognition based on changes in SCBA weight, it is inferred that even if the current firefighting SCBA weight is additionally increased to 4kg, firefighters' cognitive fatigue levels would remain similar to or not significantly higher than current levels
연구목적: 본 연구는 소방용 공기호흡기(SCBA) 중량 변화에 따른 신체 인지성 여부를 파악하고, 해당 결과를 바탕으로 소방용 공기호흡기 기준 수립 시 기초자료를 제공하고자 한다. 연구방법: 소방공무원 및 비소방공무원을 대상으로 중량이 다른 세 가지의 공기호흡기를 착용한 후 적절한 운동부하를 통해 신체 변화량, 운동자각도(RPE)및 인지성 여부를 파악 및 분석하였다. 연구결과: 소방공무원 그룹의 경우 중량이 각기 다른 공기호흡기를 착용 후 운동부하 시 호흡수, 심박수 및 혈압의 차이가 유의미하지 못했으며, 비소방공무원 그룹에서도 체중 변화량의 차이가 유의미하지 못했다. 또한, 두 그룹 모두 공기호흡기 중량 변화에 따른 운동자각도 차이를 나타내지 못했으며, 피험자 모두 실험 중 공기호흡기 중량 변화를 인지하지 못했다. 결론: 공기호흡기 중량 변화에 따른 신체 인지성은 낮은 수준이므로, 현재 사용중인 소방용 공기호흡기의 중량을 4kg까지 증대 시켜 사용하여도 소방공무원이 느끼는 피로도는 현재와 비슷한 수준이거나 높지 않을 것으로 사료된다.
