OBJECTIVE
Develop a novel work efficiency (WE) metric to quantify firefighter physical ability and identify correlates of WE.
METHODS
Physical fitness and anthropometric measurements were taken on 19 male firefighters. Firefighters performed a timed maximal effort simulated fireground test (SFGT). WE was quantified as: (1/[Air depletion × SFGT completion time]) × 10,000. Regression analyses were used to identify predictors of WE.
RESULTS
WE was significantly correlated to age, relative body fat, fat mass, occupational experience, jump height, inverted row repetitions, relative bench press and squat strength, treadmill time to exhaustion, relative ventilatory threshold, and relative peak oxygen consumption. Treadmill time to exhaustion and relative lower body strength accounted for the greatest variance in WE (R2 = 0.72, root mean square error = 0.07).
CONCLUSION
Aerobic endurance and relative lower body strength were related to an occupationally-specific assessment of firefighter physical ability.
目的
开发一种新的工作效率（WE）指标来量化消防员的身体能力，并确定与 WE 相关的因素。
方法
对 19 名男性消防员进行了体能和人体测量学测量。消防员进行了计时的最大努力模拟火场测试（SFGT）。WE 的量化方法为：（1/[空气消耗×SFGT 完成时间]）×10,000。回归分析用于确定 WE 的预测因素。
结果
WE 与年龄、相对体脂、脂肪量、职业经验、跳跃高度、倒拉重复次数、相对卧推和深蹲力量、跑步机至力竭时间、相对通气阈和相对峰值耗氧量显著相关。跑步机至力竭时间和相对下肢力量占 WE 最大变异（R2=0.72，均方根误差=0.07）。
结论
有氧耐力和相对下肢力量与消防员特定职业体能评估相关。
