“…A decreased level of physical activity could have negative impacts on the overall strength and lower-body power of LEOs, which in turn could affect the officers’ ability to successfully pursue a suspect on foot, aid in obstacle clearance and improve victim/body drag capabilities [ 18 , 19 ]. Strength is a concept of maximal force output in opposition to power, which is a measurement of velocity and how quickly force can be applied to move an external object [ 20 ]. Both strength and power are underlying components of everyday requirements of LEOs including foot pursuits, obstacle clearance, dragging, jumping, pushing and pulling.…”

Based on current law enforcement officer (LEO) duties, musculoskeletal injury risk is elevated due to the unpredictable nature of physically demanding tasks. The purpose of this 4-week study was to determine the effectiveness of a 15-min post-shift standardized occupational specific training program. The standardized program was designed to improve lower-body strength and speed to aid physically demanding task performance. Seven male LEOs completed the program after their 12-h shift. Subjects were required to use the department fitness center to perform the 15-min standardized program consisting of a dynamic warm-up, 4 sets of 3 repetitions on hex-bar deadlift and four 20-m sprints. Two minutes of rest was required between each set of 3 repetitions on hex-bar deadlift and 1 min of rest between each 20-m sprint. A dependent T-test was used between pre-test and post-test scores for hex-bar deadlift (HBD) and sprint. Data revealed significant improvements in relative lower-body strength with HBD (p ≤ 0.001). However, insignificant results were demonstrated with the 20-m sprint (p ≤ 0.262). In conclusion, a 15-min post-shift workout can improve lower-body strength as measured by the hex-bar deadlift. However, data indicated running speed may require a different training approach to improve the 20-m sprint.
