Barry Abstract OBJECTIVE: The aim of the study is to validate a customized VÝÖO 2max Graded Exercise Test (GXT) protocol specifically to accommodate firefighters with different cardiovascular fitness levels. METHODS: Career male firefighters (N = 15) completed 3 customized GXTs on a treadmill: 1 in athletic clothes and 2 in their bunker gear to determine maximal oxygen uptake (VÝÖO 2max ). RESULTS: The on-duty task protocol was reliable, VÝÖO 2max values of 40.2 Ø 4.6 mLøkgømin -1 and 40.3 Ø 5.3 mLøkgømin -1 between trials yielded an interclass correlation of 0.911 with a typical error of 1.48 mLøkgømin -1 and a coefficient of variation of 4.0%. The validity analysis indicated consistent maximal VÝÖO 2 values for the GXTs yielding mean interclass correlation of 0.94 with typical error of 1.16 mLøkgømin -1 and a coefficient of variation of 2.9%. CONCLUSIONS: The customized GXT for structural firefighters has shown to be a reliable, valid, and applicable method of testing cardiovascular fitness in firefighters.
