Exploring associations between physical fitness tests and a law enforcement specific Physical Ability Test using principal components analysis.

The purpose of this study was to determine relationships between components of physical fitness on performance in an occupation-specific physical ability test (PAT) for state patrol officers (women, n = 19; men, n = 256) using archived data. Physical fitness was assessed by 2.4 km run time (2.4 R), body fat % (BF), 1 min sit-up (SU), 1-min push-up (PU), the vertical jump (VJ), and the sit-and-reach test (SR). Principal components analysis (PCA) of the entire sample revealed that dynamic fitness (DF), related 2.4 R, SU, PU, VJ, & BF, explained 49% of variance in performance in the PAT. Lower back and hamstring flexibility explained a further 18% of variance. Law-enforcement agencies using a standard job-specific test to screen the occupational fitness of its members may use fitness tests to make fitness recommendations. Officers should prioritize developing aerobic fitness, muscular endurance, lower-body power, and flexibility to help meet the demands of occupational performance.

The Impact of Formal Strength and Conditioning on the Fitness of Law Enforcement Recruits: A Retrospective Cohort Study.

Research involving law enforcement populations has suggested better fitness could enhance job task performance and reduce injuries. Academy training should lead to improvements in recruit fitness. The aim of this study was to investigate the impact of a strength and conditioning program on fitness among law enforcement recruits. Twenty-six recruits (23 males, three females) completed a 27-week academy, which incorporated 3-4 physical training sessions per week. Fitness assessment occurred during pre- (week 0), mid- (week 14), and post-testing (week 27) time points. The fitness assessments included: vertical jump, one-minute push-ups, one-minute sit-ups, posterior chain strength measured by a leg/back dynamometer, grip strength, and aerobic fitness measured by the 20-m multistage shuttle run (MSR). A repeated measures ANOVA with Bonferroni post hoc tests determined any significant changes in fitness between time points, with alpha set at p < .05. Due to the small sample size of females, statistical analysis was only conducted on male recruits. Overall, significant main effects (p < .001) were observed in all fitness assessments except for grip strength. The results detailed general improvements in fitness. However, push-up and MSR scores decreased from mid- to post-test, while sit-ups did not change. Posterior chain strength and the vertical jump improved from mid-to post-test. The data indicated that the strength and conditioning program positively influenced the fitness of recruits. An increased focus on skill-specific work in the second-half of academy may have contributed to the plateaus in muscular endurance and aerobic fitness, and improvement of lower-body strength and power.

Comparing levels of fitness of police Officers between two United States law enforcement agencies.

BACKGROUND: The general physical task demands of law enforcement may suggest that police Officers are of similar fitness levels across cities, states and countries. OBJECTIVE: To investigate whether fitness levels of police Officers from two different United States (U.S.) Law Enforcement Agencies (LEA) are similar. METHODS: Retrospective data were analysed from two LEAs (LEA1 n = 79 and LEA2 n = 319). The data for Officers included: age, mass, 1-minute push-up repetitions, 1-minute sit-up repetitions, vertical jump height, 2.4 km run time (LEA 1) and 20-meter Multi-Stage Fitness Test results (LEA 2). Independent samples t-tests were used to compare anthropometric and fitness data between LEA with significance set at 0.05. RESULTS: Officers from LEA1 weighed significantly less and performed significantly better than Officers from LEA2 on all fitness measures. When comparing male Officers alone, there was no statistical difference in age and mass; nonetheless, Officers from LEA1 significantly outperformed Officers from LEA2 on all fitness measures. CONCLUSION: While similarities / differences in job tasks performed between these two LEA are not known, the results from this study suggest differences in fitness between these two different U.S. LEA. Fitness standards and training protocols need to be developed and contextualized to each LEA's specific population and needs.

A physical fitness profile of state highway patrol officers by gender and age.

BACKGROUND: Law enforcement officers perform physically demanding tasks that generally remain constant as they age. However, there is limited population-specific research on age, gender and normative fitness values for law enforcement officers as opposed to those of the general population. The purpose of this study was to profile the current level of fitness for highway patrol officers based on age and gender and provide percentile ranking charts unique to this population. METHODS: Retrospective data for six-hundred and thirty-one state troopers (♂ = 597; mean age = 39.52 ± 8.09 yrs; mean height = 180.72 ± 7.06 cm; mean weight = 93.66 ± 15.72 kg: ♀ = 34; mean age = 36.20 ± 8.45 years; mean height = 169.62 ± 6.65 cm; mean weight = 74.02 ± 14.91 kg) collected in 2014-2015 were provided for analysis. Data included demographic (age), anthropometric (height and weight), and select fitness (VJ, push-ups, sit ups, isometric leg/back strength, isometric grip strength and 20 m shuttle run test) information. RESULTS: There were generally significant differences between genders for all anthropometric and fitness measures, most consistently in the 30-39 age groups. While there was a general decline in push-up and shuttle run performance in female officers, these results did not reach significance. For male officers, there were significant differences between the 20-29 year-old age group and the 30-39, 40-49 and 50-59 year-old groups with the younger group performing better in VJ, push-ups, sit ups and number of shuttle runs than the older groups. There were no differences in isometric grip strength and leg back dynamometer measures between age groups. CONCLUSION: Male officers tended to be heavier, taller and perform significantly better than female officers in all measures bar sit-ups. While there appeared to be a general decline in certain physical characteristics across genders with increasing age the notable differences were between the youngest male age group (20-29 years) and all other male age groups with a potential reason being the lack of fitness requirements once typically younger cadets leave the academy. Percentile rankings for the assessed measures were found to have elements very specific to this population when compared to the general population and those provided in this paper can be used to inform future profiling and research in this population.

Physical Fitness Characteristics of High vs. Low Performers on an Occupationally Specific Physical Agility Test for Patrol Officers.

Law enforcement agencies frequently use physical ability tests (PATs) as a method of evaluating occupational performance. These tests are designed to replicate essential occupational tasks frequently performed by officers in the field. The purpose of this study was to determine whether significant relationships exist between the selected physical fitness tests and PAT performance and to determine which of these tests best differentiates between high and low PAT performers. Full-time highway patrol officers (n = 495) submitted self-reported anthropometric data (mean age = 39.6 + 7.7 years) along with fitness assessments taken from their organization's yearly fitness tests. All subjects completed a series of field-based fitness tests, as well as an occupationally specific PAT. Results of the study indicated that the selected tests accounted for almost 69% of the total variance on PAT performance. Overall, the 20-m meter multistage fitness test, 1-minute sit-up performance, and vertical jump height best predicted PAT performance. Furthermore, it was revealed that high performers were significantly more fit in all measures of dynamic fitness when compared with lower performers. No significant differences were discovered in static strength between groups. Strength and conditioning specialists should focus on developing aerobic capacity, trunk muscular endurance, and whole-body anaerobic power to improve PAT and occupational performance.
