How does time spent working in custody influence health and fitness characteristics of law enforcement officers?

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

An Analysis of the Body Drag Test in Law Enforcement Recruits with Consideration to Current Population Demographics

International Journal of Exercise Science 15(7): 276-288, 2022. An essential job task for law enforcement officers is a body drag, where they must drag a person from a hazardous environment. In California, a 9.75-m body drag with a 74.84-kg dummy must be completed within 28 s to graduate academy. This mass is less than the average US adult, which may suggest it should be increased. This has not happened due to concerns regarding a potential increase in recruit injuries and failure rates. However, if recruits can complete the drag without formal training, this could leave scope for increasing the mass. This study analyzed the body drag in incoming recruits, compared their results to graduated recruits, and detailed how many achieved current standards without training. A retrospective analysis of two incoming (n = 191) and nine graduated (n = 643) recruit classes from one agency was conducted. Incoming recruits completed the drag in the week prior to their 22-week academy; the graduated recruits in their final weeks. The drag required the recruit to lift the dummy and drag them 9.75 m. Independent samples t-tests compared the groups, and recruits were compared to the 28-s standard. Graduated recruits performed the drag faster than incoming recruits (~5.11 vs. ~7.28 s; p \u3c 0.01). All but one incoming recruit completed the drag within 28 s. Incoming recruits had sufficient strength and technical ability to drag a 74.84-kg dummy fast enough to achieve state standards before training. Further analysis should determine whether the current California body drag is appropriate for policing job demands

The Effects of Traditional versus Ability-Based Physical Training on the Health and Fitness of Custody Assistant Recruits

International Journal of Exercise Science 15(3): 1641-1660, 2022. This study investigated traditional training (TT) versus ability-based training (ABT) in custody assistant recruits. Retrospective analysis was conducted on two recruit classes who completed an 8-week academy. The TT group (18 males, 13 females) followed a physical training model where recruits completed the same exercises with the same intensity; the ABT group (17 males, 12 females) had exercises tailored towards their ability. Pre- and post-academy, recruits were assessed in: body mass; body fat percentage (BF%); resting heart rate (RHR); blood pressure (BP); waist circumference (WC); waist-to-hip ratio (WHR); grip strength; push-ups; sit-ups; YMCA step test recovery HR; 201-m run; and 2.4-km run. Independent samples t-tests evaluated between-class pre-test differences, with significance set at p ≤ 0.05. Paired samples t-tests (p ≤ 0.05) detected within-group training changes. Change scores were calculated for each variable; independent samples t-tests (p ≤ 0.05) compared change scores between groups. The TT group had lower BF%, BP, and WC; and were superior in sit-ups and the 2.4-km run before training. After academy, the TT recruits improved WHR, grip strength, recovery HR, 201-m run, and 2.4-km run, but increased diastolic BP. The ABT recruits decreased BF%, RHR, and WC, and improved push-ups, sit-ups, recovery HR, 201-m run, and the 2.4-km run. ABT recruits had greater positive changes in BF%, RHR, diastolic BP, and sit-ups. TT and ABT recruits generally experienced favorable fitness changes; the degree of positive change tended to be greater for ABT recruits for select tests. Coupled with the diastolic BP increase for TT recruits, this may provide evidence for ABT

The Effects Aerobic Fitness has on Heart Rate Responses for a Custody Assistant Recruit Class Performing a Formation Run

International Journal of Exercise Science 14(4): 1219-1233, 2021. This study measured the heart rate (HR) responses to a formation run (group run completed along a set route) performed by higher fitness (HF), moderate fitness (MF), or lower fitness (LF) custody assistant (CA) recruits. Retrospective data from 26 recruits (12 males, 14 females) were analyzed. Prior to academy training, a YMCA step test was administered. Recruits were divided into three groups based on recovery HR: top 25% were HF; bottom 25% were LF; the rest were MF. Recruit HR was measured during a formation run completed at an ~11-minute mile· pace-1. HR zones were defined as: very light (\u3c 57% of age-predicted maximum heart rate [HRmax]); light (57%-63% HRmax); moderate (64%-76% HRmax); vigorous (77%-95% HRmax); and very vigorous (\u3e 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 during the run; effect sizes (d) were also calculated. HF recruits spent a significantly longer time and percentage of total time in the very light HR zone compared to the LF group (p ≤ 0.039; d = 1.20-1.35). There were no other significant between-group differences (p = 0.070-0.980). HF CA recruits spent more time in the very light training zone compared to the other groups (d = 0.92-1.35), which may not be optimal for aerobic adaptations. LF recruits spent more time in the vigorous-to-very vigorous HR zones (~45 minutes; 70% of the run). These recruits may potentially be working above their current capacity. Formation runs may not be the most efficient aerobic conditioning method for all CA recruits

The Health and Fitness Characteristics of Civilian Jailer Recruits Prior to Academy Training

International Journal of Exercise Science 15(4): 58-78, 2022. Civilian jailer (CJ) recruits may not complete fitness testing within their hiring process. As certain job tasks in custody/jail facilities can be physically demanding (e.g., inmate restraint), better health and fitness should help a recruit graduate from a CJ academy and be prepared for the occupation. This study investigated the health and fitness characteristics of CJ recruits entering academy training, detailed between-sex differences, and categorized recruits relative to population norms. Retrospective analysis was conducted on data from 89 CJ recruits (48 males, 41 females) across three academy classes from one law enforcement agency. The following were measured before academy: resting heart rate (RHR); blood pressure (BP); height, body mass, and body mass index (BMI); waist circumference; sit-and-reach; grip strength; 60-s push-ups; and YMCA step test recovery heart rate (HR). Independent samples t-tests derived any between-sex differences. Recruit data were compared to categorical population norms. The results indicated that male recruits were taller, heavier, had greater grip strength, and completed more push-ups than female recruits (p \u3c 0.001). Approximately 53% of recruits were overweight or obese according to BMI, ~63% had an RHR below average-to-very poor, and ~75% had elevated BP or hypertension. Most recruits had good-to-excellent flexibility (sit-and-reach; ~66%) and muscular endurance (push-ups; ~85%). However, ~70% of recruits had fair-to-poor grip strength, and ~79% had poor-to-very poor aerobic fitness measured by step test recovery HR. Aerobic conditioning and strength training should be a focus of CJ recruits during academy. Furthermore, better aerobic fitness should benefit job performance and lessen cardiovascular disease risk
