Key result
Physical and fitness characteristics, including height, pull-ups, push-ups, and 1.5-mile run, explained most of the variance in heart rate responses during and after a simulated fireground test.
Why the study?
Previous studies have not measured associations between heart rate responses during simulated fireground tasks with a standardized work rate, and there is a need to evaluate physical and fitness characteristics related to attenuated physiological stress.
Do physical and fitness characteristics influence heart rate dynamics during and after a simulated fireground test in firefighter recruits?
Cross-Sectional (n=21)
Do physical and fitness characteristics influence heart rate dynamics during and after a simulated fireground test in firefighter recruits?
Physical and fitness characteristics, such as height, pull-ups, push-ups, and run time, are associated with heart rate dynamics and recovery following simulated fireground tasks.

Fitness traits may guide recruit screening; hypothesis-generating for performance optimization without causal evidence.
Saari et al. (2023) conducted a cross-sectional in Healthy structural firefighter recruits (n=21). Physical and fitness characteristics was evaluated on Heart rate reserve (HRRes), change in heart rate variability (LnRMSSDRest-Post), and 60-second post-SFGT heart rate recovery (HRR60). Physical and fitness characteristics, including height, pull-ups, push-ups, and 1.5-mile run, explained most of the variance in heart rate responses during and after a simulated fireground test.
