Abstract

Simulated fire ground scenarios (SFGS) provide firefighters an opportunity to maintain their skills and receive team feedback in order to optimize their performance. Although there is extensive research on heart rate (HR) changes in the firefighter population, very few have examined these differences between positions.

Purpose/Objective:
To quantify the physical demands of SFGS among Firefighting crews by position through HRV analysis.

Methods:
Sixty-eight male (age: 38.97 ± 9.17; ht: 177.99 ± 6.45 cm. wt: 88.83 ± 13.55 kg) firefighters volunteered to participate in this research. Firefighting crews performed two SFGS involving the suppression and control of a structural fire, while wearing personal protective equipment (PPE) and using a self-contained breathing apparatus (SCBA). Subjects were outfitted with heart rate (HR) monitors and weighed immediately prior to performing a SFGS. Average heart rate (HRavg) and maximum heart rate (HRmax) data was collected and recorded for each of the two scenarios performed by each crew.

Results:
During SFGS it was discovered that HRavg ranged between 54 – 88% (of APMHR and average HRmax ranged between 73– 106% of APMHR.

Conclusions:
SFGS are very physically demanding events that may elicit maximal or near maximal heart rate responses regardless of positon. Practical Application: Based on the metabolic demands of these events and the individual firefighter’s capabilities, this information can be used to develop conditioning programs
that optimize performance at maximal or near maximal heart rates.
