Key result
CBRN simulation training significantly decreased mean RR interval (p=0.01) and state anxiety (p=0.02) from pre- to post-training in first responders, with stress-adapted individuals demonstrating higher parasympathetic activity.
Why the study?
Data are limited regarding stress induced in responders wearing CBRN equipment, and inter-individual variability in psychological, cognitive, and physiological adaptation remains poorly understood.
Does simulated CBRN training alter physiological (HRV) and psychological stress responses in first responders?
Observational (n=28)
No
Does simulated CBRN training alter physiological (HRV) and psychological stress responses in first responders?
p-value: p=0.01
First responders exhibit significant psycho-physiological stress responses during CBRN simulations, with heart rate variability serving as a marker for stress adaptation.
No takes yet. Share an insight, caveat, or question.
CBRN simulation may reduce anxiety in first responders; leaves open whether HRV identifies stress-adapted individuals for targeted training.
Giaume et al. (2023) conducted an observational in Physiological and psychological stress in first responders (n=28). CBRN simulation training with personal protective equipment vs. Baseline (pre-training) was evaluated on Mean RR interval (Heart rate variability) (p=0.01). CBRN simulation training significantly decreased mean RR interval (p=0.01) and state anxiety (p=0.02) from pre- to post-training in first responders, with stress-adapted individuals demonstrating higher parasympathetic activity.
