Abstract: To analyze the potential factors influencing the psychological and physiological states of firefighters during smoke and heat training, this study employed an intelligent smoke and heat training device for firefighters and utilized a feature data correlation analysis model. By collecting 16 indicators (including heart rate, electroencephalogram, and heart rate variability) from 100 firefighters during smoke and heat training, the research explored the factors affecting their psychological and physiological states in such training. The results showed that both age and firefighters' daily psychological states had a p-value less than 0.01 with their psychological states during smoke and heat training, indicating that younger firefighters were more prone to psychological problems during training, and regulating their daily psychological states could alleviate psychological pressure during smoke and heat training. The p-value for years of service versus training duration was 0.054, with a regression coefficient of -19.494, indicating that firefighters with longer service experience exhibited shorter training durations. The p-value for resting heart rate and training oxygen consumption was merely 0.016, with a regression coefficient of -0.128, indicating that firefighters with lower resting heart rates exhibited reduced oxygen consumption. The p-value for body weight and training duration exceeded 0.5, suggesting a relatively insignificant correlation between the two variables.
