Validity and Reliability of Firefighting Simulation Test Performance

To assess the validity and reliability of a firefighting simulation test (FFST). Sixty-nine operational firefighters completed a best-effort FFST on one occasion and twenty-two participants completed a further FFST. All participants completed a maximal treadmill test to determine cardiorespiratory fitness (VO2max). Time to complete the FFST demonstrated a strong inverse relationship with VO2max (r = -0.73), although the prediction error was high. Reliability of the FFST was high (r = 0.84, p = 0.01), demonstrating a coefficient of variation of 4.5%. The FFST demonstrated reasonable validity as a surrogate assessment of cardiorespiratory fitness for firefighting. The FFST also demonstrated good reliability. Given the apparent magnitude of the prediction error, the FFST would be best used as a training tool, rather than as a primary means of assessing cardiorespiratory fitness for firefighting.
