Abstract

Fitness testing is employed by some law enforcement agencies to assure performance in occupational tasks. The aim of this study was to investigate associations between musculoskeletal fitness assessment scores and performance in police occupational tasks. Retrospective data from 106 law enforcement officers who completed five musculoskeletal fitness assessments (vertical jump (VJ), hand grip strength, leg back dynamometer, 1-minute push-ups and sit-ups) and three routine occupational tasks (1.22m fence jump (FJ), 8.5m victim drag (VD) with 101kg and a get-up (GU)) were collected. A standard multiple regression was performed to determine if the results in fitness assessments were predictive of performance in the occupational tasks. Models combining all fitness assessments significantly predicted performance in FJ (F(5,88)=12.228, p<0.001; adjusted R2=0.38), VD (F(5,88)=9.407, p<0.001; adjusted R2=0.31) and GU (F(5,87)=14.319, p<0.001; adjusted R2=0.42). Further analysis of individual predictors highlighted that performance in the VJ test was a significant contributor for all models, uniquely predicting 15% of FJ (p<0.001), 4% of VD (p=0.03) and 8% of GU (p=0.001) performance. Grip strength uniquely contributed 3% to performance in the VD (p=0.05) and performance in the sit-up test contributed 8% to GU performance (p=0.001). Performance in police-specific occupational tasks requires a combination of muscular strength, power, and endurance. These musculoskeletal fitness components should be ideally assessed in recruitment and return-to work practices to ensure officers can safely and optimally perform their occupational requirements.
