Heart Rate & PSI

	FGT (n = 13)	Live-fire training evolution (n = 14)
Pre-Task HR (bpm)	89 ± 12	82 ± 13
Post-Task HR (bpm)	178 ± 4*	178 ± 19*
Cylinder Gauge Difference (PSI)	2,346.2 ± 275.7	3,335.7 ± 486.8**
Console Gauge Difference (PSI)	2,176.9 ± 404.5	3,382.5 ± 588.1**

Values represent mean ± standard deviation. FGT = fire grounds test; HR = heart rate; PSI = pounds per square inch.

^*Denotes significantly higher (p ≤ 0.01) heart rate values compared to baseline.

^**Denotes significantly lower PSI depletion (p ≤ 0.01) for both the cylinder and console gauge between tasks.
