Why the study?

Firefighters face high-risk situations where psychological coping is crucial, but correlations between cardiac autonomic modulation, risk-taking behavior, and resilience needed examination.

Population

20 male professional firefighters

Comparison

Physical exercise vs no exercise during a realistic deployment in a fire container

Overview

May support HRV as a monitoring tool for firefighter risk and resilience traits; leaves open validation in larger prospective studies.

Structured PICO

P
Population
20 male professional firefighters in active fire service from the professional fire brigade of Berlin, average age 37.8 years.
I
Intervention
Simulated extinguish-fire task in a burning container with physical exercise (rowing ergometer) (n=10)
C
Comparator
Simulated extinguish-fire task in a burning container without physical exercise (sitting calmly) (n=10)
O
Outcome
Correlations between cardiac autonomic modulation (HRV indices including RMSSD, LF/HF ratio), risk-taking behavior (R-1 scale), and resilience (RS-13 scale)surrogate

In professional firefighters, heart rate variability indices correlate with psychological traits such as risk-taking behavior and resilience during simulated stressful tasks.

Limitations

  • Small sample size
  • Further studies are warranted for validation
