Abstract
ABSTRACT Lockie, RG, Beitzel, MM, Dulla, JM, Dawes, JJ, Orr, RM, and Hernandez, JA. Between-sex differences in the work sample test battery performed by law enforcement recruits: implications for training and potential job performance. J Strength Cond Res 36(5): 1310-1317, 2022-Law enforcement officers perform a range of demanding job-specific tasks, and these tasks are the same for all officers, regardless of sex. Female officers tend to be at a physical disadvantage compared with male officers, and this could affect their performance in job-specific tasks. This study investigated the between-sex differences in the work sample test battery (WSTB; duplicates what an officer encounters on-duty) in law enforcement recruits. A retrospective analysis was performed on 308 recruits (259 men and 49 women) from 5 training academy classes. The WSTB incorporated 5 tests: a 99-yard obstacle course (99OC), 165-pound body drag (BD), 6-foot chain link fence (CLF), solid wall (SW) climb, and 500-yard run (500R). These tests were typically performed in the last weeks of academy and must be completed to a state-mandated minimum standard for recruits to graduate. Independent-samples t tests (p < 0.05) and effect sizes (d) calculated between-sex differences. Noting that when individual data were considered, there were male recruits who were outperformed by female recruits. However, on average, female recruits were slower on all WSTB tasks than male recruits (p < 0.01). Large effects were present for the 99OC, CLF, and 500R differences (d = 1.26-1.69), a moderate effect for the BD (d = 0.85), and a small effect for the SW (d = 0.56). Slower performance in job-specific tests could translate to slower performance in tasks required on-duty. Training staff should develop the qualities necessary for WSTB performance in female recruits and underperforming male recruits to enhance future job performance.

INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2021; 18:11676. [PMID: 34770190 PMCID: PMC8582849 DOI: 10.3390/ijerph182111676] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 09/25/2021] [Revised: 11/02/2021] [Accepted: 11/04/2021] [Indexed: 12/25/2022]
Abstract
Law enforcement agencies generally employ the "one-size-fits-all" education-training model. Its effectiveness compared to alternative training models has been under scrutiny. Physical fitness scores of Serbian male (n = 98) and female (n = 79) police cadets during their yearly evaluation were compared. Cadets trained for the first 3 years with the "one-size-fits-all" model. In the fourth year, they self-prescribed an individualized exercise program based on the obtained curriculum knowledge. A two-way MANOVA revealed a significant effect of academic years on combined variables (p < 0.001) and significant differences between academic years for deadlift, half squat, standing long jump, sit-ups and 12-min Cooper test time (p < 0.001). Sex also had a significant main effect on combined variables (p < 0.001) with males outscoring females on all of the fitness assessments. For pull-ups, there was a significant year * sex interaction (p = 0.01) with the third year to be pivotal for female and male performance, respectively. In conclusion, the use of a "one-size-fits-all" model, presented differences in physical fitness scores between the years one to three, pointing to its questionable effectiveness. On the contrary, the self-prescribed individualized exercise program of the fourth year elicited greater fitness scores, indicating the need to evaluate the applicability of such a training model more.

Abstract
This study investigated the influence of time spent working in custody on the health and fitness of law enforcement officers (LEOs). Retrospective analysis was conducted on data from 48 male and 12 female LEOs, divided into groups based upon time spent working custody: LEO ≤ 24 (≤24 months; n = 15); LEO 2547 (25-47 months; n = 24); and LEO 48+ (≥48 months; n = 21). The following were measured: body mass index (BMI); fat mass percentage; waist-to-hip ratio (WHR); resting heart rate (RHR); blood pressure; grip strength; sit-and-reach; push-ups; sit-ups; and YMCA step test recovery heart rate (HR). A univariate ANCOVA (controlling for sex and age) with Bonferroni post hoc determined significant between-group differences. Select assessments were compared to normative data. The LEO 48+ group completed fewer sit-ups than the LEO 2547 group (p = 0.006); there were no other significant between-group differences. Forty-nine LEOs were overweight or obese according to BMI; 52 were fatter than average or above; 27 had a WHR that increased cardiovascular disease risk. Forty-three LEOs had very poor RHR; 52 had elevated blood pressure. Forty-eight LEOs had average-to-very poor step test recovery HR. Irrespective of time spent working in custody, personnel should be physically active to maintain health and fitness and, where possible, engage in formal strength training and conditioning.

Abstract
BACKGROUND Law enforcement agencies often include fitness testing as part of the hiring process. However, it can be months from this testing to when a recruit starts academy. OBJECTIVE To determine fitness changes from hiring to academy in recruits who graduate (GRAD) or separate (SEP; do not complete) from academy. METHODS Analysis on recruits from one agency, split into GRAD (n = 436) and SEP (n = 78) groups, was conducted. These tests were conducted during initial hiring and academy: push-ups, sit-ups, and arm ergometer revolutions in 60 s; 75-yard pursuit run (75PR); and 2.4 km run. Data were analyzed via a two-way repeated measures ANOVA. Change scores were derived between hiring and academy data for both groups, and analyzed via independent samples t-tests. RESULTS Push-ups, 75PR, arm ergometer, and 2.4 km run generally improved (p≤0.001). There were no significant between-group interactions or differences in performance changes for GRAD and SEP recruits. SEP recruits tended to have lesser fitness test performance compared to GRAD recruits. CONCLUSIONS GRAD and SEP recruits showed some fitness improvements between initial hiring through to academy. However, SEP recruits with lesser muscular endurance, running speed, and aerobic capacity during hiring did not substantially improve by academy, which likely impacted their academy survivability.

Abstract
ABSTRACT Martinez, GJ and Abel, MG. Effect of a law enforcement academy training program on validated fitness outcomes of cadets. J Strength Cond Res 35(4): 955-962, 2021-The purpose of this investigation was to assess the efficacy of a law enforcement training program on physical fitness outcomes in police cadets. A convenience sample of 138 male and 8 female police cadets participated in a 23-week law enforcement training academy with validated fitness assessments conducted at entrance, midpoint, and exit from the academy. Demographic, anthropometric, and fitness data (i.e., 1.5-mile run, 1 repetition maximum bench press, sit-up repetitions, push-up repetitions, and 300-m run) were retrospectively collected. Analysis of variance was used to identify the influence of training on fitness outcomes over time and between cadet subgroup stratifications. Statistical significance for this study was set at p ≤ 0.05. All cadet subgroups (specialty-stratified and sex-stratified cohorts) exceeded the validated fitness standards on academy entrance and exit (p ≤ 0.01). The entire cohort significantly improved all fitness outcomes throughout the training program. Furthermore, improvements in all fitness outcomes were significantly greater from entrance to midpoint (4.4-35.7%, p ≤ 0.001) vs. midpoint to exit (1.2-15.4%, p < 0.05). Specifically, there were greater relative improvements in push-ups and sit-ups (57.5 and 28.7%, respectively; p < 0.001) compared with bench press (13.8%, p < 0.001), 300-m run (5.8%, p < 0.001), and 1.5-mile run (12.1%, p < 0.001). Regarding female cadets, the average relative improvement in fitness outcomes from entrance to exit assessments was superior compared to male counterparts for all fitness tests except sit-ups. Moreover, the specialty cadets produced lower 1.5-mile run times than nonspecialty cadets throughout the academy. Overall, the academy improved occupationally relevant fitness outcomes, with greater improvements occurring earlier in the academy.

Abstract
This study captured heart rate (HR) responses of custody assistant (CA) recruits undertaking circuit training sessions. Data from 10 male and 12 female CA recruits were analyzed. Based on YMCA step test recovery HR, recruits were divided into higher fitness (HF; top 25%), lower fitness (LF; bottom 25%), and moderate fitness (MF; remaining recruits) groups. HR was measured during two circuit training sessions featuring calisthenics and running. HR zones were defined as: very light (<57% of age-predicted maximum heart-rate [HRmax]); light (57-63% HRmax); moderate (64-76% HRmax); vigorous (77-95% HRmax); and very vigorous (>95% HRmax). A one-way ANOVA, with Bonferroni post hoc, calculated between-group differences in time spent, and percentage of total time, in the HR zones. In session one, the LF group spent less time in the light training zone compared to the MF group, and more time in the very vigorous zone compared to the HF group (p = 0.027-0.047). In session two, the LF group spent more time in the moderate zone compared to both groups, and a greater percentage of time in the very vigorous zone compared to the MF group (p = 0.002-0.004). LF recruits generally worked harder during circuit training than their fitter counterparts, which supported recommendations for ability-based modifications.

We Need You: Influence of Hiring Demand and Modified Applicant Testing on the Physical Fitness of Law Enforcement Recruits. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2020; 17:ijerph17207512. [PMID: 33076438 PMCID: PMC7602546 DOI: 10.3390/ijerph17207512] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 07/29/2020] [Revised: 10/12/2020] [Accepted: 10/13/2020] [Indexed: 11/16/2022]
Abstract
A challenge for law enforcement agencies is the many positions that need filling. Agencies may modify their applicant test battery (ATB; multilevelled testing including fitness, background checks, psychological evaluations) to increase the hiring pool of potential recruits by augmenting the utility of testing. This study determined fitness differences of law enforcement recruits hired under two different ATB protocols. Retrospective analysis was conducted on seven academy classes (442 males, 84 females) hired under an older ATB, and one class (45 males, 13 females) hired under a newer ATB. Recruits completed the following before academy: 60 s push-ups and sit-ups (muscular endurance); vertical jump (lower-body power); medicine ball throw (upper-body power); 75 yard pursuit run (75PR; change-of-direction speed); and 20 m multistage fitness test (20MSFT; aerobic fitness). Independent sample t-tests (p ≤ 0.001) and effect sizes (d) evaluated between-group fitness differences for recruits hired under the different ATB protocols (combined sexes, males, and females). There were no significant differences between the ATB groups. However, newer ATB female recruits completed 13% fewer 20MSFT shuttles than the older ATB group, which, although not significant (p = 0.007), did have a moderate effect (d = 0.62). Females hired under the newer ATB had lower aerobic fitness, which could impact physical training performance and graduation.

Lockie, RG, Dawes, JJ, Orr, RM, and Dulla, JM. Recruit fitness standards from a large law enforcement agency: Between-class comparisons, percentile rankings, and implications for physical training. J Strength Cond Res 34(4): 934-941, 2020-Law enforcement can be a physically demanding profession. Many agencies use a "one-size-fits-all" academy training approach, which may not be optimal for all recruits. There is also little information that benchmarks fitness of law enforcement recruits. The purpose of this study was to analyze between-academy class differences in fitness, as well as produce normative data for the development of strength and conditioning programs. A retrospective analysis of 908 recruits (761 men and 147 women), comprising 11 classes from one agency, was used. Fitness assessment data included push-ups, sit-ups, and mountain climbers in 120 seconds; pull-ups; 201-m run; and 2.4-km run. A one-way analysis of variance with a Bonferroni post hoc adjustment revealed that fitness varied significantly between classes. Class 11 completed less sit-ups than 6 other classes (p ≤ 0.033) and were slower in the 201-m and 2.4-km run than 5 classes (p ≤ 0.005). Class 7 completed less push-ups than 3 classes (p ≤ 0.036) and less mountain climbers and were slower in the 201-m run than 5 classes (p ≤ 0.005). Individual recruit analysis and percentile data indicated a wide spread of all assessment results and the effects upon female recruits. For example, 81% of women completed ≤2 pull-ups and were in the bottom 2 percentile bands; 72-76% of women were in the bottom 3 bands for push-ups and the 201-m run. Fitness varies from class-to-class, and female recruits will generally be less physically fit. Training staff should ideally implement individualized, ability-based programming where appropriate to train their recruits.
