Abstract

OBJECTIVE

The aim of the study is to validate a customized V˙O 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 (V˙O 2max ).

RESULTS

The on-duty task protocol was reliable, V˙O 2max values of 40.2 ± 4.6 mL·kg·min -1 and 40.3 ± 5.3 mL·kg·min -1 between trials yielded an interclass correlation of 0.911 with a typical error of 1.48 mL·kg·min -1 and a coefficient of variation of 4.0%. The validity analysis indicated consistent maximal V˙O 2 values for the GXTs yielding mean interclass correlation of 0.94 with typical error of 1.16 mL·kg·min -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.

摘要

目的

本研究的目的是验证一种定制的最大摄氧量分级运动试验（GXT）方案，专门用于适应不同心血管健康水平的消防员。

方法

职业男性消防员（N = 15）在跑步机上完成了3次定制的GXT：1次穿着运动服，2次穿着消防服，以确定最大摄氧量（V˙O2max）。

结果

执勤任务方案可靠，两次试验之间的V˙O2max值分别为40.2±4.6 mL·kg·min-1和40.3±5.3 mL·kg·min-1，组间相关系数为0.911，典型误差为1.48 mL·kg·min-1，变异系数为4.0%。效度分析表明，GXT的最大V˙O2值一致，组间平均相关系数为0.94，典型误差为1.16 mL·kg·min-1，变异系数为2.9%。
