PMID 35917080WHAT IT FOUND
Injury risk during police training was significantly higher for female recruits and those aged 30 or older.
Lower limb and shoulder injuries caused the most time away from training, suggesting prevention efforts should target these areas and high-risk groups.
Key findings
01Female sex and age 30 years or older were significant risk factors for injury, with hazard ratios of 1.4 and 1.5 respectively.
02Lower limb injuries accounted for 64.9% of all injuries, while shoulder injuries represented the second-highest injury burden.
03The overall injury prevalence was 20.1%, with an incidence rate of 2.00 injuries per 1000 training days.

What it does not show
The study relied on retrospective analysis of prospectively collected data, which may contain minor coding errors as data extraction was performed by a single author without independent cross-checking. 10.2% of records lacked demographic data (age or sex), and some injuries were classified as 'unspecified' or 'non-specific' due to incomplete descriptions. The database did not differentiate between subsequent and recurrent injuries, so only index injuries were included in the statistical model. Exposure was measured in training days rather than specific session duration or intensity metrics, limiting the precision of the load-injury relationship.
The easy way to misread this
Do not interpret the hazard ratios as evidence that a specific intervention will reduce injury risk in these groups. This study identifies who is at higher risk and where injuries occur, but it does not test any preventive strategies.
