소방용 공기호흡기 중량 변화에 따른 신체 인지성 연구

초록

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
