The general physical task demands of law enforcement may suggest that police Officers are of similar fitness levels across cities, states and countries.
To investigate whether fitness levels of police Officers from two different United States (U.S.) Law Enforcement Agencies (LEA) are similar.
Retrospective data were analysed from two LEAs (LEA1 n = 79 and LEA2 n = 319). The data for Officers included: age, mass, 1-minute push-up repetitions, 1-minute sit-up repetitions, vertical jump height, 2.4 km run time (LEA 1) and 20-meter Multi-Stage Fitness Test results (LEA 2). Independent samples t-tests were used to compare anthropometric and fitness data between LEA with significance set at 0.05.
Officers from LEA1 weighed significantly less and performed significantly better than Officers from LEA2 on all fitness measures. When comparing male Officers alone, there was no statistical difference in age and mass; nonetheless, Officers from LEA1 significantly outperformed Officers from LEA2 on all fitness measures.
While similarities / differences in job tasks performed between these two LEA are not known, the results from this study suggest differences in fitness between these two different U.S. LEA. Fitness standards and training protocols need to be developed and contextualized to each LEA's specific population and needs.
执法工作的一般体力任务要求可能表明,不同城市、州和国家的警察体能水平相似。
调查来自美国两个不同执法机构(LEA)的警察体能水平是否相似。
对两个执法机构(LEA1,n = 79;LEA2,n = 319)的回顾性数据进行分析。警察的数据包括:年龄、体重、1分钟俯卧撑重复次数、1分钟仰卧起坐重复次数、垂直跳高度、2.4公里跑步时间(LEA 1)和20米多级体能测试结果(LEA 2)。采用独立样本t检验比较两个执法机构之间的人体测量和体能数据,显著性水平设定为0.05。
在所有体能指标上,LEA1的警察体重显著更轻,表现显著优于LEA2的警察。仅比较男性警察时,年龄和体重没有统计学差异;尽管如此,LEA1的警察在所有体能指标上仍显著优于LEA2的警察。
虽然这两个执法机构执行的工作任务的异同尚不清楚,但本研究结果表明这两个不同的美国执法机构在体能方面存在差异。需要根据每个执法机构的特定人群和需求制定体能标准和训练方案。
