Injury Profiles of Police Recruits Undergoing Basic Physical Training: A Prospective Cohort Study.

Purpose A lack of published epidemiological data among police recruits presents a major challenge when designing appropriate prevention programs to reduce injury burden. We aimed to report the injury epidemiology of Western Australian (WA) Police Force recruits and examine sex and age as injury risk factors. Methods Retrospective analyses were conducted of prospectively collected injury data from WA Police Force recruits between 2018-2021. Injury was defined as 'time-loss' and injury incidence rate per 1000 training days (Poisson exact 95% confidence intervals) was calculated. For each region and type of injury, the incidence, severity, and burden were calculated. The association between age, sex, and injury occurrence were assessed using Cox regression time-to-event analysis. Results A total of 1316 WA Police Force recruits were included, of whom 264 recruits sustained 304 injuries. Injury prevalence was 20.1% and the incidence rate was 2.00 (95%CI 1.78-2.24) injuries per 1000 training days. Lower limb injuries accounted for most of the injury burden. Ligament/ joint injuries had the highest injury tissue/pathology burden. The most common activity injuring recruits was physical training (31.8% of all injuries). Older age (Hazard Ratio = 1.5, 95%CI = 1.2 to 1.9, p = 0.002) and female sex (Hazard Ratio = 1.4, 95%CI = 1.3 to 1.6, p < 0.001) increased risk of injury. Conclusion Prevention programs targeting muscle/tendon and ligament/joint injuries to the lower limb and shoulder should be prioritised to reduce the WA Police Force injury burden. Injury prevention programs should also prioritise recruits who are over 30 years of age or of female sex, given they are a higher risk population.

Cardiorespiratory fitness is a risk factor for lower-limb and back injury in law enforcement officers commencing their basic training: a prospective cohort study.

We aimed to report the epidemiology of lower-limb and lumbosacral injuries in Police Force recruits. We performed a cohort study of Police Force recruits undergoing a six-month training program with prospective injury data collected between 2018 and 2021. Cardiorespiratory fitness was quantified by the beep-test and police-specific-functional-capacity was quantified using a specifically designed physical performance evaluation (PPE) tool. Injury frequency and prevalence were reported. Fifteen percent (n = 180) of study Police Force recruits (n = 1,181) sustained a lower-limb or lumbosacral injury. The six-month training program significantly improved cardiorespiratory fitness (p < 0.001) and functional capacity (p < 0.001). Increased cardiorespiratory fitness at baseline decreased injury risk (OR = 0.8, 95%CI: 0.66-0.97, p = 0.019). Injury rates decreased over time and females were injured significantly earlier than males (HR = 0.70, 95%CI: 0.52 to 0.95, p = 0.021). Interventions that can pre-condition Police Force recruits prior to the commencement of their basic physical training may reduce the number of lower-limb and lumbosacral injuries.
