Abstract：
UNASSIGNED: Firefighter physical fitness (PF) plays a crucial role in mitigating health issues and supporting occupational performance. The influence of rank on firefighter PF remains understudied and previous research is often limited by small sample sizes of firefighters volunteering for research studies, potentially biasing results towards fitter firefighters not representative of entire departments.
UNASSIGNED: To examine the PF profile of firefighters in a large urban fire department and the influence of age and rank on PF.
UNASSIGNED: Data, including muscular fitness, estimated aerobic capacity (VO2max), and body fat percentage (BF%) measures from 1361 firefighters (90% male; age: 37.4±10.1yrs; 60 recruits, 973 firefighters, 290 lieutenants/captains, 38 chiefs) were analyzed. Correlation and ANCOVAs were conducted to examine the impact of rank on PF while controlling for age. Score distributions were scrutinized to profile the PF of the department.
UNASSIGNED: Age was negatively associated with pull-ups (r = - 0.39), sit-ups (r = - 0.39), and push-ups (r = - 0.32), but positively associated with relative VO2max (r = 0.17) and BF% (r = 0.39). Rank had a statistically significant, but trivial effect size, on pull-ups (p = 0.028, η2 = 0.007) and sit-ups (p = 0.034, η2 = 0.005). Firefighters with lower PF levels were older, had higher BF%, lower fat-free mass, and were a greater proportion of females.
UNASSIGNED: Firefighters exhibited diverse levels of PF. Age, not rank, appeared to influence firefighters\' PF. The findings that firefighters who were older, female, with poorer body composition are more likely to have lower PF levels highlights the need for individualized PF training to enhance occupational performance and health across the fire department.

摘要：
■消防员的身体素质（PF）在缓解健康问题和支持职业表现方面起着至关重要的作用。等级对消防员PF的影响仍未得到充分研究，并且先前的研究通常受到自愿参加研究的消防员样本量小的限制。潜在的偏向于不代表整个部门的更健康的消防员的结果。
■检查大型城市消防部门消防员的PF概况以及年龄和等级对PF的影响。
■数据，包括肌肉健身，估计有氧能力(VO2max)，1361名消防员（90％男性；年龄：37.4±10.1岁；60名新兵，973名消防员290名中尉/上尉，38位酋长）进行了分析。进行相关性和ANCOVA以检查等级对PF的影响，同时控制年龄。对分数分布进行了仔细检查，以概述该部门的PF。
■年龄与引体向上呈负相关（r=-0.39），仰卧起坐（r=-0.39），和俯卧撑(r=-0.32)，但与相对VO2max(r=0.17)和BF%(r=0.39)呈正相关。排名具有统计学意义，但微不足道的影响大小，引体向上（p=0.028，η2=0.007）和仰卧起坐（p=0.034，η2=0.005）。PF水平较低的消防员年龄较大，具有较高的BF%，较低的无脂肪质量，女性比例更高。
■消防员表现出不同程度的PF。年龄,不是等级,似乎影响了消防员\'PF。发现年长的消防员，女性,身体成分较差的人更有可能有较低的PF水平，这突出了个性化PF培训的必要性，以提高整个消防部门的职业表现和健康。
