Recruit fitness and police academy performance: a prospective validation study.

BACKGROUND: Police academies need fit recruits to successfully engage in training activities. In a previous retrospective study, we documented that recruits with poor fitness at entry to the academy had significantly lower graduation rates, and we also suggested evidence-based entry-level fitness recommendations. AIMS: To validate our findings in a prospective cohort of police recruits. METHODS: Recruits entering Massachusetts municipal police academies during 2015-16 were followed prospectively until they dropped out, failed or successfully graduated their academy classes. Entry-level fitness was quantified at the start of each training class using: body composition, push-ups, sit-ups, sit-and-reach and 1.5-mile run time. The primary outcome of interest was the odds of failure (not successfully graduating from an academy). We used logistic regression to assess the probability of not graduating, based on entry-level fitness. RESULTS: On average, successful graduates were leaner and possessed better overall entry-level fitness. After adjusting for age, gender and body mass index, several fitness measures were strongly associated with academy failure: fewer sit-ups completed (OR 9.6 (95% CI 3.5-26.3) (≤15 versus 41-60)); fewer push-ups completed (OR 6.7 (95% CI 2.5-17.5) (≤20 versus 41-60)); and slower run times (OR 18.4 (95% CI 6.8-50.2) (1.5 miles in > 15 min 20 s versus 10 min 37 s to 12 min 33 s)). The prospective study results supported previously suggested minimum entry-level fitness (95% graduation rate) and target (98% graduation rate) recommendations. CONCLUSIONS: Push-ups completed and 1.5-mile run time at police academy entry were successfully validated as predictors of successful academy graduation, while sit-ups were also a strong independent predictor in the prospective study.

Recruit Fitness as a Predictor of Police Academy Graduation.

BACKGROUND: Suboptimal recruit fitness may be a risk factor for poor performance, injury, illness, and lost time during police academy training. AIMS: 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. METHODS: 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. RESULTS: 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″]). CONCLUSIONS: 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.
