Suboptimal recruit fitness may be a risk factor for poor performance, injury, illness, and lost time during police academy training.
To assess the probability of successful completion and graduation from a police academy as a function of recruits' baseline fitness levels at the time of academy entry.
Retrospective study where all available records from recruit training courses held (2006-2012) at all Massachusetts municipal police academies were reviewed and analysed. Entry fitness levels were quantified from the following measures, as recorded at the start of each training class: body composition, push-ups, sit-ups, sit-and-reach, and 1.5-mile run-time. The primary outcome of interest was the odds of not successfully graduating from an academy. We used generalized linear mixed models in order to fit logistic regression models with random intercepts for assessing the probability of not graduating, based on entry-level fitness. The primary analyses were restricted to recruits with complete entry-level fitness data.
The fitness measures most strongly associated with academy failure were lesser number of push-ups completed (odds ratio [OR] = 5.2, 95% confidence interval [CI] 2.3-11.7, for 20 versus 41-60 push-ups) and slower run times (OR = 3.8, 95% CI 1.8-7.8, [1.5 mile run time of ≥15'20″] versus [12'33″ to 10'37″]).
Baseline pushups and 1.5-mile run-time showed the best ability to predict successful academy graduation, especially when considered together. Future research should include prospective validation of entry-level fitness as a predictor of subsequent police academy success.
招募人员的体能不达标可能是导致其在警察学院培训期间表现不佳、受伤、患病和缺勤的一个风险因素。
评估招募人员在入读警察学院时的基础体能水平作为成功完成和毕业的概率。
回顾性研究，分析了 2006 年至 2012 年在马萨诸塞州所有市政警察学院举行的所有新兵培训课程的所有可用记录。入学体能水平是通过以下措施来量化的，这些措施记录在每个培训课程开始时：身体成分、俯卧撑、仰卧起坐、坐立前伸和 1.5 英里跑步时间。主要关注的结果是从学院毕业的几率。我们使用广义线性混合模型来拟合具有随机截距的逻辑回归模型，以根据入门级体能评估不毕业的概率。主要分析仅限于具有完整入门级体能数据的新兵。
与学院失败最相关的体能测试是完成的俯卧撑数量较少（优势比 [OR] = 5.2，95%置信区间 [CI] 2.3-11.7，对于 20 次与 41-60 次俯卧撑）和较慢的跑步时间（OR = 3.8，95% CI 1.8-7.8，[1.5 英里跑时间≥15'20″]与[12'33″至 10'37″]）。
基础俯卧撑和 1.5 英里跑步时间显示出最好的预测成功毕业的能力，尤其是当一起考虑时。未来的研究应包括将入门级体能作为预测后续警察学院成功的指标进行前瞻性验证。
