Maintenance of good levels of physical fitness is essential during occupational tasks for the general health of the military police. However, no studies have evaluated longitudinal changes in the physical fitness of Brazilian military police officers according to their specialties. Thus, the objective of the current study was to analyze the changes in the physical fitness of military police officers according to their specialty, over a period of five years. Retrospective data (2015-2019) from 290 police officers were analyzed, including age and physical fitness tests (12-min run test, sit-ups, push-ups, and pull-ups on the bar). The sample was divided into four groups (Specialized; Border; Urban; and Environmental). ANCOVA was used to describe differences in physical fitness components between groups of police officers after adjusting for age. Initial fitness was higher among police officers in the Specialized group (i.e., those with greater physical demands). During the five-year follow-up period, there was an age-related decrease in physical capacity for all groups, regardless of specialty. However, Urban police showed improvement in running and sit-up tests ( < 0.05) over time. Changes in physical capacity during follow-up differed depending on the physical component analyzed and the occupational specialty.
维持良好的身体体能水平对于军警的整体健康至关重要。然而，目前还没有研究根据军警的专业来评估其身体体能的纵向变化。因此，本研究的目的是分析五年期间军警根据其专业的身体体能变化。对 290 名警察的回顾性数据（2015-2019 年）进行了分析，包括年龄和体能测试（12 分钟跑测试、仰卧起坐、俯卧撑和引体向上）。样本分为四个组（专业组、边境组、城市组和环境组）。在调整年龄后，使用协方差分析（ANCOVA）描述警察各分组之间的体能成分差异。在初始体能方面，专业组（即体能要求较高的组）的警察表现出更高的体能。在五年的随访期间，所有组的体能都随着年龄的增长而下降，但城市组的跑步和仰卧起坐测试有所改善（<0.05）。随访期间身体能力的变化取决于所分析的身体成分和职业专业。
