Bloodgood, AM, Dawes, JJ, Orr, RM, Stierli, M, Cesario, KA, Moreno, MR, Dulla, JM, and Lockie, RG. Effects of sex and age on physical testing performance for law enforcement agency candidates: implications for academy training. J Strength Cond Res 35(9): 2629-2635, 2021-Law enforcement candidates are often required to complete fitness tests to assess their preparedness for training. This study investigated the influence of sex and age on candidate performance before academy training. Retrospective analysis of 516 candidates was performed. Data were stratified into men (n = 432) and women (n = 84), and the pooled (men and women combined) data were stratified into age groups (20-24; 24-29; 30-34; 35-39; and 40+ years). The tests included the following: maximal push-ups and sit-ups in 60 seconds; a 75-yard pursuit run (75PR); arm ergometer revolutions completed in 60 seconds; and a 2.4-km run. To compare the sex and age groups, a 2 × 5 analysis of variance (with Bonferroni post hoc for multiple between-age group comparisons) was used. Men performed significantly (p < 0.001) more push-ups, sit-ups, and arm ergometer revolutions and were faster in the 75PR and 2.4-km run. The 20-24, 25-29, and 35-39 year groups were faster in the 75PR compared with the 40+ year group; the 20-24 and 25-29 year groups were faster than the 35-39 year group; and the 20-24 year group was faster than the 30-34 year group (p ≤ 0.023). The 20-24 year group was faster than the 40+ year group in the 2.4-km run (p = 0.005). Women and older candidates may have a lower physical capacity than men and younger candidates, respectively, in certain physical assessments. Women and older candidates, in particular, may benefit from dedicated training before academy to better prepare for the demands of this period.

Physical fitness assessments for tactical occupations (e.g., military, law enforcement, and emergency services) can include predictive tests of anaerobic power, cardiovascular fitness, muscular endurance, muscular power, strength, agility, and/or simulated occupational tasks. Not only can these tests be used to assess the ability of someone to undertake the job role but they can be used to determine injury risk, training failure, and/or general health. This review discusses different uses for physical fitness assessments and considerations for their use in tactical populations.

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.

PurposeThe aims of this study were to evaluate fitness levels in a cohort of police trainees and compare these results to other police trainees and the general population.Design/methodology/approachRetrospective data for 274 male and 152 female police trainees were supplied. Measures included height, body mass and physical appraisal test (PAT; 2.4 km run, vertical jump, push-ups and grip strength) results, assessed twice, prior to commencement of training, separated by several months. Wilcoxon signed rank tests were used to analyze non-parametric initial and final PAT scores and Mann–WhineyUtests were used to determine variance between groups.FindingsMale trainees were significantly quicker in the run (−12%,p p p p p = 0.002).Originality/valueWhen compared to the general population from which they were drawn and to other law enforcement trainees, the police trainees in this study were quicker, more powerful and stronger. While there was no loss of fitness between initial and final PAT performance, a conditioning program, spanning the periods between initial and final PAT may be of benefit to increase fitness prior to training commencement especially for female trainees who were generally less fit than, yet must complete the same training as, male trainees.

Lockie, RG, Carlock, BN, Ruvalcaba, TJ, Dulla, JM, Orr, RM, Dawes, JJ, and McGuire, MB. Skeletal muscle mass and fat mass relationships with physical fitness test performance in law enforcement recruits before academy. J Strength Cond Res 35(5): 1287-1295, 2021-The purpose of this study was to analyze relationships between skeletal muscle mass percentage (SMM%) and fat mass percentage (FM%) relative to fitness test performance in law enforcement recruits. Retrospective analysis was conducted on 338 recruits (271 men and 67 women) from 4 academy classes. Skeletal muscle mass percentage and FM% were measured using cost-effective and practical bioelectrical impedance analysis (BIA) equipment that used hand and foot placement. The fitness tests included grip strength; vertical jump; 75-yard pursuit run; 2-kg medicine ball throw (MBT); push-ups and sit-ups completed in 60 seconds; and the 20-m multistage fitness test. Partial correlations controlling for sex-derived relationships between SMM%, FM%, and the tests. Recruits were split into quartile groups for SMM% and FM% (group 1 had the lowest SMM% or highest FM% and group 4 the highest SMM% or lowest FM%). A 1-way multivariate analysis of variance (MANOVA), with sex as a covariate and Bonferroni post-hoc, compared between-group results. Skeletal muscle mass percentage correlated with all fitness tests expect for MBT; FM% with all but grip strength and MBT (r = ±0.107-0.293). Greater SMM% or lesser FM% tended to relate to better fitness test performance. The MANOVA data indicated groups 3 and 4 (better SMM% or FM% profiles) exhibited superior fitness than group 1 (poorest SMM% or FM% profile) (p ≤ 0.048). Recruits should ideally increase SMM% and decrease FM% before academy to optimize fitness training and testing performance, although specific guidelines should be agency specific. Staff could use BIA to monitor body composition during academy to indicate how recruits are tolerating training.

Lockie, RG, Dawes, JJ, Dulla, JM, Orr, RM, and Hernandez, E. Physical fitness, sex considerations, and academy graduation for law enforcement recruits. J Strength Cond Res 34(12): 3356-3363, 2020-This study investigated the influence of fitness on academy graduation, and any between-sex differences, in law enforcement recruits. Data collected at the start of 4 training academies were retrospectively analyzed, including age, height, and body mass; waist circumference; waist-to-hip ratio; grip strength; vertical jump (VJ); 75-yard pursuit run; 2-kg medicine ball throw (MBT); push-ups, sit-ups, and arm ergometer revolutions in 60 seconds; and 20-m multistage fitness test (20MSFT) shuttles. Recruits were categorized into graduated (GRAD = 269) and separated (did not graduate; SEP = 42) groups. SEP recruits were not split according to separation reasons, just whether they did or not. This categorization also occurred for male subjects (GRAD = 228; SEP = 32) and female subjects (GRAD = 41; SEP = 10). Independent samples t-tests calculated between-group differences for all recruits combined, male subjects, and female subjects. Correlations and stepwise linear regression calculated relationships between the data and graduation. The t-test (p ≤ 0.016) and correlation (r = ±0.137-0.296; p < 0.05) data indicated that SEP recruits (both sexes combined) were older and performed poorer in every fitness test except grip strength and VJ. SEP male subjects were older and performed poorer in all tests except grip strength (p ≤ 0.009). SEP female subjects scored lower in the arm ergometer (p = 0.008). The regression equation for all recruits found that age, 20MSFT (aerobic fitness), MBT (upper-body power), and arm ergometer (upper-body endurance) were academy graduation predictors (r = 0.169; p < 0.001). For the male recruits, the predictors were age, MBT, and 20MSFT (r = 0.182; p ≤ 0.001), and for female recruits, arm ergometer and 20MSFT (r = 0.213; p ≤ 0.003). Recruits should improve multiple fitness aspects, including muscular endurance, power, and aerobic fitness, to enhance graduation potential.

This study investigated whether: law enforcement recruits could complete a 74.84-kg (165-lb) body drag without specific training; relationships between the body drag and absolute and relative isometric grip and leg/back strength could be established to assist with training recommendations; a strength baseline needed to complete the 74.84-kg body drag could be established. Retrospective analysis on a recruit class (72 males, 21 females) from one agency was conducted. Recruits completed the body drag, and had strength assessed by hand grip and leg/back dynamometers in the week before academy. The body drag required the recruit to lift the dummy to standing and drag it 9.75 m as quickly as possible. Independent samples t-tests calculated between-sex differences in the drag and strength measures. Recruits were ranked according to drag time to describe the strength of recruits that could not perform the task. Pearson’s correlations and a stepwise linear regression calculated relationships between the body drag and isometric strength. Male recruits completed the drag faster and were stronger than females (p < 0.001). Only two females could not complete the drag, and they had leg/back strength below 100 kg. Greater absolute (r = -0.599 and -0.677) and relative (r = -0.261 and -0.322) grip (combined score) and leg/back strength, respectively, related to a faster drag. Absolute leg/back strength predicted the body drag (r2 = 0.444). Improving absolute isometric grip and leg/back strength could enhance dragging ability. A minimum isometric leg/back strength score of 100 kg may be needed to perform a 74.84-kg body drag.

The purpose of this study was to explore the relationship between two measures of trunk muscular endurance. Retrospective data for 520 male law enforcement officers (age 40.16 ± 7.71 years; height = 1.81 ± 0.07 m; body mass = 94.4 ± 15.01 kg) belonging to a single US based law enforcement agency were used for this analysis. The data provided included: age, height, body mass, sit-up repetitions completed in 1-min (SU) and time to completion for the isometric prone plank (IPP). A Pearson’s product correlation coefficient was used to determine the relationships between the SU and IPP. Significant (P

Background Attrition rate in new army recruits is higher than in incumbent troops. In the current study, we identified the risk factors for attrition due to injuries and physical fitness failure in recruit training. A variety of predictive models were attempted. Methods This retrospective cohort included 19,769 Army soldiers of the Australian Defence Force receiving recruit training during a period from 2006 to 2011. Among them, 7692 reserve soldiers received a 28-day training course, and the remaining 12,077 full-time soldiers received an 80-day training course. Retrieved data included anthropometric measures, course-specific variables, injury, and physical fitness failure. Multivariate regression was used to develop a variety of models to predict the rate of attrition due to injuries and physical fitness failure. The area under the receiver operating characteristic curve was used to compare the performance of the models. Results In the overall analysis that included both the 28-day and 80-day courses, the incidence of injury of any type was 27.8%. The 80-day course had a higher rate of injury if calculated per course (34.3% vs. 17.6% in the 28-day course), but lower number of injuries per person-year (1.56 vs. 2.29). Fitness test failure rate was significantly higher in the 28-day course (30.0% vs. 12.1%). The overall attrition rate was 5.2 and 5.0% in the 28-day and 80-day courses, respectively. Stress fracture was common in the 80-day course (n = 44) and rare in the 28-day course (n = 1). The areas under the receiver operating characteristic curves for the course-specific predictive models were relatively low (ranging from 0.51 to 0.69), consistent with “failed” to “poor” predictive accuracy. The course-combined models performed somewhat better than the course-specific models, with two models having AUC of 0.70 and 0.78, which are considered “fair” predictive accuracy. Conclusion Attrition rate was similar between 28-day and 80-day courses. In comparison to the 80-day full course, the 28-day course had a lower rate of injury but a higher number of injuries per person-year and of fitness test failure. These findings suggest fitness level at the commencement of training is a critically important factor to consider when designing the course curriculum, particularly short courses.

PurposeTo determine the relationship between metabolic fitness test scores and performance in police occupational tasks.MethodsRetrospective data from 106 law enforcement officers who completed two metabolic fitness assessments [anaerobic: a 20-m (10-m and 20-m splits) sprint, aerobic: 20 m Multi-Stage Fitness Test (20 m-MSFT)] and three routine occupational tasks [1.22 m Fence jump (FJ), 8.5 m Victim Drag (VD with 102.3 kg) and “Get-up” (GU)] were collected. A Person’s correlation coefficient and a standard multiple regression were used to assess the relationship between and predictive ability of, respectively, the fitness tests scores and performance on occupational tasks.ResultsThere was a significant positive correlation between the 10-m sprint scores and FJ (r = 0.524,P r = 0.528,P r = 0.486,P r = 0.573,P r = 0.603,P r = 0.533,P r = − 0.360,P r = − 0.266,P = 0.012) and GU (r = − 0.375,P ConclusionHigh levels of metabolic fitness correlated with faster performance in police officer occupational tasks, particularly ones of an anaerobic nature (i.e. the maximal sprint tests). In addition to typical aerobic fitness conditioning, anaerobic fitness conditioning could be vital for optimal performance in physically demanding tasks required of police officer.

BACKGROUND - Height and body mass are often self-reported by study participants. However, the accuracy of this data compared to measured values is limited in tactical trainee populations. This study's purpose was to compare the accuracy of self-reported height and body mass to measured values within a US law enforcement cadet population, and determine how these estimations affected BMI classifications. METHODS - Self-reported and measured body height and body mass for twenty-six (n = 26) male and female cadets (males - age: 31.32 ± 10.04 years; measured height: 178.07 ± 9.87 cm; measured body mass: 92.44 ± 19.37 kg; females - age: 25.67 ± 1.53 years; measured body height: 168.17 ± 4.01cm; measured body mass: 78.94 ± 11.30 kg) were analyzed. RESULTS - Significant differences between estimated and measured height (p < 0.001), body mass (p < 0.05), but not BMI (p = 0.281) were revealed. CONCLUSION - Self-reported body height and body mass were not accurately reported when compared to measured values. However, reported resulted in accurate BMI classifications.

Introduction The intense training and occupational demands of military personnel place the individual at risk of serious injury. When they do occur, serious personal injuries (SPIs) can lead to medical discharge, mission compromise, and ongoing recurrence of problems. Prior to the implementation of any minimization strategies, an understanding of the causes of SPIs requires development. The aim of this study was to analyze the incidence rates and patterns of SPIs within the Australian Regular Army (ARA) and Australian Army Reserve (ARES). Methods Data for a 2-year period were obtained through the Work Health, Safety, Compensation, and Reporting database of the Australian Department of Defence. Records of SPIs were extracted, with details including: (a) the activity being performed when the injury was suffered; (b) the body location of injury; (c) the nature of injury; and (d) the mechanism of injury. Results were reported as number of SPIs and converted to SPIs/100 full-time equivalent (FTE) years of service. Results In total, 507 SPIs were reported over the two-year period (ARA = 466; ARES = 41). SPIs most commonly: occurred during combat training (n = 80; 0.13 SPIs/100 FTE years) and physical training (n = 66; 0.10 SPIs/100 FTE years); affected the head (n = 63; 0.10 SPIs/100 FTE years) and shoulders (n = 57; 0.09 SPIs/100 FTE years); and comprised fractures (n = 199; 0.19 SPIs/100 FTE years) and soft-tissue injuries (n = 103; 0.16 SPIs/100 FTE years). The most common mechanism of injury was falls (n = 132; 0.21 SPIs/100 FTE years) or contact with objects (n = 114; 0.18 SPIs/100 FTE years). When adjusted for service time, ARES personnel were found to report SPIs more frequently than ARA personnel (0.87 vs. 0.79/100 FTE years, respectively) giving an injury risk ratio (ARA:ARES) of 0.91 [95% CI = 0.66–1.25]. Conclusions Despite higher absolute numbers of SPIs occurring in ARA, ARES in fact report similar rates of SPIs when adjusted for service time. The natures and mechanisms of SPIs are also similar for both service types and therefore should be the focus of targeted programs to reduce such injuries.

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.

Soldiers are often required to carry heavy loads that can exceed 45 kg. The physiological costs and biomechanical responses to these loads, whilst varying with the contexts in which they are carried, have led to soldier injuries. These injuries can range from musculoskeletal injuries (e.g., joint/ligamentous injuries and stress fractures) to neurological injuries (e.g., paresthesias), and impact on both the soldier and the army in which they serve. Following treatment to facilitate initial recovery from injuries, soldiers must be progressively reconditioned for load carriage. Optimal conditioning and reconditioning practices include load carriage sessions with a frequency of one session every 10–14 days in conjunction with a program of both resistance and aerobic training. Speed of march and grade and type of terrain covered are factors that can be adjusted to manipulate load carriage intensity, limiting the need to adjust load weight alone. Factors external to the load carriage program, such as other military duties, can also impart physical loading and must be considered as part of any load carriage conditioning/reconditioning program.

Background Law enforcement personnel have been recognized as having a high risk for several lifestyle-related health conditions which, in combination with the nature of their work (sedentary roles interspersed with intermittent high-intensity activity, shift work, and a high stress-load), can have a negative impact on their health. The aim of this study was to investigate the dietary habits and factors or barriers influencing these habits within a cohort of law enforcement personnel in the United States of America. Method Cross-sectional data were obtained via validated paper-based surveys being the Perceived Barriers to Healthy Eating, Food Choice Questionnaire and Rapid Eating Assessment for Participants, Short Version. Results A total of 159 participants (median age = 27 [range 19–60] years; 74% males) participated. Barriers to healthy eating included being busy and irregular working hours. Overall, 91% (n = 143) placed high importance on consuming nutritious food and 80% (n = 126) on food high in vitamins and minerals. A further 80% (n = 127) emphasized high protein content and 41% (n = 62) followed a high protein diet. Barriers to healthy eating included busy lifestyle (60%, n = 94), and irregular working hours (41%, n = 64). Overall, 80% (n = 127) were very willing to make changes in eating habits to be healthier. Conclusion Law enforcement officers know what they should eat and report convenience and health the most important factors guiding their food choices. Knowing this, officers find challenges putting good dietary practices into practice due to factors like a busy lifestyle and irregular work hours. Reportedly “very willing” to make changes in their eating habits to be healthier, future interventions should focus on how to effect changes to their eating habits as opposed to focussing on what to eat.

This study investigated differences in the body composition of police officers from different occupational groups and the moderation effects of leisure time physical activity (LTPA). A sample of 237 police officers (special anti-terrorist unit, gendarmerie, firefighters, and general duties) participated in the study. Body mass index (BMI), percent of body fat (%BF), percent of skeletal muscle mass (%SMM), and index of hypokinesia (IH) were assessed using a multichannel bioelectric impedance analyzer and officers reported the amount of LTPA using an international physical activity questionnaire. The sample was divided in three groups relative to LTPA, sedentary (0&ndash, 149 min/week), moderately active (150&ndash, 299 min/week), and very active (300+ min/week). Multiple analysis of variance (4 &times, 3) was used to analyze if occupational groups differed based solely on occupation, if officers from the same occupation differed in muscularity and fatness based on LTPA, and if any differences in body composition occurred between officers from different occupations with the same level of LTPA. Police officers from more physically demanding occupations demonstrated lower %BF and IH, while having higher %SMM. This was also observed among the officers of the same occupation who reported a higher LTPA, while officers who reported very high LTPA had similar body composition.

Physical fitness is an important aspect of physical health and wellbeing. The aim of this study was to investigate the effects of 11-weeks of formal strength and conditioning training conducted during fire academy training on the physical fitness characteristics of firefighter trainees. Archived physical fitness data for 23 male fire academy trainees (age: 27.6 ± 4.3 y; height: 178.5 ± 6.9 cm; body mass [BM]: 83.9 ± 1.8 kg; BM index [BMI]: 26.8 ± 2.8 kg/m2) were analyzed for this study. These data included vertical jump height, maximum pull-up repetitions, hand grip strength, lower-body strength (3RM Hexbar) and aerobic fitness. Trainees performed three sessions per week (two resistance training sessions and one aerobic conditioning session) in addition to fire academy training. A repeated measures ANOVA revealed significant (p < 0.05) pre-post decreases in BM and BMI and significant increases in upper- and lower-body strength, and aerobic fitness. Strength and conditioning programs are beneficial for improving firefighter trainees’ physical fitness even when run concurrently with fire academy training and with limited space and equipment. This increased fitness may aid in mitigating known occupational injury risks to this population and improve task performance.

Introduction The primary aim of Reserve Officers’ Training Corps (ROTC) programs is to prepare cadets for future military service. To successfully complete one of these programs and perform active duty responsibilities, cadets must be able to complete a variety of physical tasks. Therefore, performing movement screening may be useful for identifying potential movement disparities that could lead to injury. The purpose of this investigation was to determine whether sex-related differences in movement patterns exist on the Functional Movement Screen (FMS). The FMS is a tool that uses seven functional movements to assess movement pattern deficits and asymmetries; deep squat, hurdle step, inline lunge (ILL), shoulder mobility, active straight-leg raise (ASLR), trunk stability pushup (TSPU), and rotary stability. Materials and Methods Archived data for 93 (male, n = 69; female n = 24) ROTC cadets were provided to the primary investigators for analysis. Independent t-tests (P Results Significant differences between sexes were observed on the ILL (P = .014), ASLR (P Conclusions Sex differences in the ILL, ASLR, and TSPU may be because of greater mobility in the ankle and hamstrings and reduced upper-body muscle mass for females compared with males. Males performed better than females on the TSPU test. In conclusion, sex-related differences in FMS performance do exist within the ROTC population. Additionally, these differences should be taken into consideration when designing specific exercise programs for ROTC cadets.

Background The law enforcement officer profession requires performance of arduous occupational tasks while carrying an external load, consisting of, at minimum, a chest rig, a communication system, weaponry, handcuffs, personal protective equipment and a torch. The aim of this systematic review of the literature was to identify and critically appraise the methodological quality of published studies that have investigated the impacts of body armour on task performance and to synthesize and report key findings from these studies to inform law enforcement organizations. Methods Several literature databases (Medline, CINAHL, SPORTDiscus, EMBAS) were searched using key search words and terms to identify appropriate studies. Studies meeting the inclusion criteria were critically evaluated using the Downs and Black protocol with inter-rater agreement determined by Cohen’s Kappa. Results Sixteen articles were retained for evaluation with a mean Downs and Black score of 73.2 ± 6.8% (k = 0.841). Based on the research quality and findings across the included studies, this review determined that while effects of body armour on marksmanship and physiological responses have not yet been adequately ascertained, body armour does have significant physical performance and biomechanical impacts on the wearer, including: a) increased ratings of perceived exertion and increased time to complete functional tasks, b) decreased work capability (indicated by deterioration in fitness test scores), c) decreased balance and stability, and d) increased ground reaction forces. Conclusions Given the physical performance and biomechanical impacts on the wearer, body armour should be carefully selected, with consideration of the physical fitness of the wearers and the degree to which the armour systems can be ergonomically optimized for the specific population in question.

Gait analysis is one aspect of evaluation in ambulatory children with cerebral palsy (CP). Ankle-foot orthoses (AFOs) improve gait and alignment through providing support. An alternative and under-researched orthosis are sensomotoric orthoses (SMotOs). The Edinburgh Visual Gait Score (EVGS) is a valid observational gait analysis scale to measure gait quality. The aim of this study was to use the EVGS to determine what effect AFOs and SMotOs have on gait in children with CP. The inclusion criteria were: mobilizing children with a CP diagnosis, no surgery in the past six weeks, and currently using SMotOs and AFOs. Eleven participants were videoed walking 5 m (any order) barefoot, in SMotOs and AFOs. Of the participants (age range 3&ndash, 13 years, mean 5.5 &plusmn, 2.9), two were female and six used assistive devices. Seven could walk barefoot. Participants had spastic diplegia (4), spastic quadriplegia (6), and spastic dystonic quadriplegia (1). Gross Motor Functional Classification System (GMFCS) levels ranged I&ndash, IV. The total score for SMotOs (7.62) and AFOs (14.18) demonstrated improved gait when wearing SMotOs (no significant differences between barefoot and AFOs). SMotOs may be a viable option to improve gait in this population. Additional study is required but SMotOs may be useful in clinical settings.

Background In the conduct of their daily duties, law enforcement officers (LEO) are often required to perform dynamic, physically demanding tasks with little or no notice, sometimes at maximal levels of exertion. Given these requirements, training for prospective LEOs must be rigorous enough to ensure that when trainees graduate, they are competent in their response to crisis and resilient enough to maintain this for the span of their career. Therefore, based on previously reported effectiveness of fitness testing in predicting injury risk in predominantly military settings, the aim of this study was to investigate relationships between a physical ability test (PAT) and risk of injury during police recruit training. Methods Retrospective PAT results and trainee injury records were obtained from a national police department and Mann-Whitney U tests were performed to investigate fitness differences between trainees who were, or were not, injured. Significant results were tested for effect size using Cliff’s delta (CD). Results Significant differences in mean performance between groups existed for the following PAT components: pushups (injured mean 32.94 ± 8.66 reps, uninjured mean 35.67 ± 9.04 reps, p = 0.01 CD + 0.11) and right-hand grip strength (injured mean 49.61 ± 12.51 kg, uninjured mean 52.12 ± 11.17 kg, p = 0.042 CD + 0.22) for all injuries; vertical jump height (injured mean 51.75 ± 7.54 cm, uninjured mean 55.06 ± 8.19 cm, p = 0.032 CD + 0.41) for lower limb injuries, and all measures of grip strength for trunk injury. Conclusions The results of this study suggest that a significant relationship between some PAT fitness components and injury risk exists during police recruit training.

IntroductionThe United States Army Rangers are a unique population whose training requirements are intensive, and physically and mentally demanding. The Functional Movement Screen (FMS) is a movement screening tool designed to assess movement quality and asymmetries in movement with the potential to identify injury risk. This study was a descriptive, cross-sectional investigation examining associations between FMS scores and the various measures of health and performance of active duty soldiers in light infantry units who were involved in the U.S. Army Pre-Ranger Course (PRC).Materials and MethodsBefore the PRC, 491 male soldiers (mean age = 24.0 ± 3.8 years; mean height = 176.6 ± 7.2 cm; mean body mass = 80.2 ± 9.8 kg) completed a questionnaire which included items on self-assessed physical fitness, last Army physical fitness test (APFT) score, tobacco use, and injury history. The soldiers then completed the FMS, which consisted of seven movements and three clearing tests. From the FMS results, a determination of asymmetries (i.e., differences in FMS scores between the right and left side of the body) was made. Differences between groups were analyzed via an independent sample t-test, a one-way analysis of variance, or a chi-square as appropriate. Significance was set at 0.05 a priori.ResultsThe average composite FMS score was 16.4 (±1.9) points. Soldiers reporting ≥290 APFT points achieved a higher FMS score than those reporting lower APFT scores (16.5 ± 2.0 vs 16.1 ± 2.0 points, P = 0.03). Soldiers reporting either tobacco use or a previous musculoskeletal injury had lower FMS scores than those not reporting these (tobacco: 16.1 ± 2.1 vs 16.5 ± 1.8 points, P = 0.02; injury: 16.0 ± 2.2 vs 16.6 ± 1.8 points, P ConclusionsActive duty soldiers of a light infantry division achieved FMS scores similar to other military populations tested, and the composite FMS score was related to higher APFT scores, absence of tobacco use, and absence of previous musculoskeletal injuries. Improving PRC candidate healthy habits through highlighting the negative associations between poorer fitness, cigarette tobacco use and movement quality, may reduce injury risk and increase PRC completion potential.

Objectives Osteoarthritis (OA) is a common disorder which affects the joints. As relationships between occupational factors and lower limb OA have been widely studied in systematic reviews, the aim of this umbrella review was to synthesize their key findings in the risk factors for development of lower limb OA. Methods A systematic search was conducted using the databases PUBMED, Cumulative Index of Nursing and Allied Health Literature, and Elton B Stevens Company to identify reviews examining associations between lower limb OA and occupational tasks. These reviews were rated for their methodological quality before key data were extracted and synthesized. Results Sixteen reviews were found, seven pertained to the knee, four to the hip, two to a variety of joints, and three to both the hip and knee. One was deemed to be of high methodological quality, one of critically low methodological quality, and the others of moderate methodological quality. The reviews found moderate to good evidence for heavy occupational lifting to be associated with an increased risk of OA at the knee and the hip. Kneeling, squatting, and climbing, previous injuries to joints, being overweight and obese were also predictive of lower limb OA. Conclusion Occupations which involve heavy physical workloads increase the risk of developing lower limb OA. Heavy lifting, squatting, knee bending, kneeling, and climbing may all increase the risk of developing OA in both the knees and hips. Efforts to reduce exposure to these tasks, reducing joint injuries, optimizing bodyweight may reduce the risks of lower limb OA for occupations which are physically demanding.

ObjectiveTactical personnel (Military, Law Enforcement, Emergency Responders) require physical fitness levels sufficient for training and occupational duty. Physical conditioning aimed at increasing fitness levels during training presents an injury risk, but unfit trainees may struggle to meet occupational performance standards, further increasing injury risk to themselvesor others. Therefore, the aim of this review was to determine if fitness, asquantified by tactical fitness tests, effectively predicts injury risk during training.MethodsLiterature databases were search and relevant articles extracted. 27 Publications were included for qualitative review and seven studies reporting a timed run were included in meta-analysis.ResultsThe combined risk ratio was 2.34 (95% CI 2.02 to2.70). Muscular endurance tests were less conclusive in their predictive abilities. Functional strength or power tests were effective predictors, but few studies reported on strength or power, indicating a need for further study inthis area.ConclusionsThe meta-analysis results are supported by the occupational relevance of run tests; tactical trainees are required to perform frequent bouts of distance weight bearing activity. However, given the diverse physical requirements of tactical personnel, measures of strength and power should alsobe evaluated, especially given their effectiveness in the studies that included these measures.

Context: Part-time personnel are an integral part of the Australian Army. With operational deployments increasing, it is essential that medical teams identify the patterns of injuries sustained by part-time personnel in order to mitigate the risks of injury and optimize deployability.Objective: To compare the patterns of reported work health and safety incidents and injuries in part-time and full-time Australian Army personnel.Design: Retrospective cohort study.Setting: The Australian Army.Patients or Other Participants: Australian Army Reserve and Australian regular Army populations, July 1, 2012, through June 30, 2014.Main Outcome Measure(s): Proportions of reported work health and safety incidents that resulted in injuries among Army Reserve and regular Army personnel and specifically the (a) body locations affected by incidents, (b) nature of resulting injuries, (c) injury mechanisms, and (d) activities being performed when the incidents occurred.Results: Over 2 years, 15 065 work health and safety incidents and 11 263 injuries were reported in Army Reserve and regular Army populations combined. In the Army Reserve population, 85% of reported incidents were classified as involving minor personal injuries; 4% involved a serious personal injury. In the regular Army population, 68% of reported incidents involved a minor personal injury; 5% involved a serious personal injury. Substantially lower proportions of Army reservist incidents involved sports, whereas substantially higher proportions were associated with combat training, manual handling, and patrolling when compared with regular Army incidents.Conclusions: Army reservists had a higher proportion of injuries from Army work-related activities than did regular Army soldiers. Proportions of incidents arising from combat tasks and manual handling were higher in the Army Reserve. Understanding the sources of injuries will allow the medical teams to implement injury-mitigation strategies.

Context: Police academy training must physically prepare cadets for the rigors of their occupational tasks to prevent injury and allow them to adequately perform their duties. Objective: To compare the effects of 2 physical training programs on multiple fitness measures in police cadets. Design: Cohort study. Setting: Police training academy. Patients or Other Participants: We collected data from 70 male (age = 27.4 ± 5.9 years, body weight = 85.4 ± 11.8 kg) and 20 female (age = 30.5 ± 5.8 years, body weight = 62.8 ± 11.0 kg) police cadets and analyzed data from 61 male cadets (age = 27.5 ± 5.5 years, body weight = 87.7 ± 13.2 kg). Intervention(s): Participants completed one of two 6-month training programs. The randomized training group (RTG; n = 50), comprising 4 separate and sequential groups (n = 13, n = 11, n = 13, n = 13), completed a randomized training program that incorporated various strength and endurance exercises chosen on the day of training. The periodized group (PG; n = 11) completed a periodized training program that alternated specific phases of training. Main Outcome Measure(s): Anthropometric fitness measures were body weight, fat mass, and lean body mass. Muscular and metabolic fitness measures were 1-repetition maximum bench press, push-up and sit-up repetitions performed in 1 minute, vertical jump, 300-m sprint, and 2.4-km run. Results: The RTG demonstrated improvements in all outcome measures between pretraining and posttraining; however, the improvements varied among the 4 individual RTGs. Conversely, the PG displayed improvements in only 3 outcome measures (push-ups, sit-ups, and 300-m sprint) but approached the level of significance set for this study (P < .01) in body weight, fat mass, and 1-repetition maximum bench press. Conclusions: Regardless of format, physical training programs can improve the fitness of tactical athletes. In general, physical fitness measures appeared to improve more in the RTG than in the PG. However, this observation varied among groups, and injury rates were not compared.

Introduction The aim was to investigate whether therapeutic massage was effective in relieving pain in elderly residents with dementia. Methods A randomized controlled study was conducted in an aged care facility. Ten participants with dementia or advanced dementia were allocated to an intervention group or a control group. The intervention group received 10 min of massage (effleurage, kneading, and trigger point therapy) four times per week for 4 weeks. The Pain Assessment in Advanced Dementia scale was used as the outcome measure. Results No significant changes in mean outcome measure scores were found post intervention (Intervention mean = 5.0 ± 3.49; Control mean = 5.2 ± 3.49: t(8) = 0.09, p = 0.93). However, the Intervention Group had a greater magnitude of change (1.200 ± 1.78) when compared to the control group (0.800 ± 2.16). Conclusion Therapeutic massage may provide a useful adjunct to the current pain management plan of patients with dementia.

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 (&lt, 57% of age-predicted maximum heart-rate [HRmax]), light (57&ndash, 63% HRmax), moderate (64&ndash, 76% HRmax), vigorous (77&ndash, 95% HRmax), and very vigorous (&gt, 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&ndash, 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&ndash, 0.004). LF recruits generally worked harder during circuit training than their fitter counterparts, which supported recommendations for ability-based modifications.

This systematic review and meta-analysis identified and critically reviewed the findings of recent studies (last 15 years) examining relationships between specific physically demanding occupations or occupational tasks and development of lower limb osteoarthritis (OA). Twenty-eight studies with 266,227 cases of lower limb OA were included. Occupational tasks contributing to OA included farming, floor laying, and brick laying. Activities significantly contributing to the risk of knee OA were lifting heavy loads (>10 kg/week) (odds ratio [OR] = 1.52, 95% confidence interval [95%CI] 1.29–1.79), squatting/kneeling (OR = 1.69, 95%CI 1.15–2.49), standing (>2 h/daily) (OR = 1.22 95%CI 1.02–1.46) and walking (OR = 1.40 95%CI 1.14–1.73). Lifting contributed significantly to the risk of hip OA (OR = 1.35, 95%CI 1.16–1.57). The effects of occupational exposures appear to be magnified by previous injury and BMI >25 kg/m2. Since specific occupational activities increase OA risk, ergonomist should encourage the use of existing tools, or oversee the design of new tools that may decrease exposure to such activities.

The purpose of this research was to investigate the effects of a physical training program and semester break periods on the chosen physical abilities and basic body composition indicators among police trainees. Body weight (BW), waist circumference (WC), push-ups (PU), sit-ups (SU) and 2.4 km run (RUN) times of 420 male trainees attending the Abu Dhabi Police College were collected. The testing was conducted by the police education centre during routine testing periods (June, September, December, May) which bracketed the semesters and could be used to investigate the impacts of the physical training program and any potential detraining occurring over the semester break. A repeated measure analysis of variance was performed to identify changes in results across the time periods with a Bonferroni post-hoc adjustment to identify where differences, if any, lay. The level of significance was set at 0.05 a priori. Following the semester break period from June to September, BW, WC and RUN increased significantly (p

Suitable grip strength is a police occupational requirement. The aim of this study was to investigate the association between grip strength, task performance and injury risk in a police population. Retrospective data of police recruits (n = 169) who had undergone basic recruit training were provided, including handgrip strength results, occupational task performance measures (consisting of police task simulations [SIM], tactical options [TACOPS] and marksmanship assessments) and injury records. Left hand grip strength (41.91 ± 8.29 kg) measures showed a stronger correlation than right hand grip strength (42.15 ± 8.53 kg) with all outcome measures. Recruits whose grip strength scores were lower were significantly more susceptible to failing the TACOPS occupational task assessment than those with greater grip strength scores, with significant (p ≤ 0.003) weak to moderate, positive correlations found between grip strength and TACOPS performance. A significant (p < 0.0001) correlation was found between grip strength, most notably of the left hand, and marksmanship performance, with those performing better in marksmanship having higher grip strength. Left hand grip strength was significantly associated with injury risk (r = −0.181, p = 0.018) but right hand grip strength was not. A positive association exists between handgrip strength and police recruit task performance (notably TACOPS and marksmanship) with recruits who scored poorly on grip strength being at greatest risk of occupational assessment task failure.

Introduction Many injuries experienced by soldiers can be attributed to the occupational loads they are required to carry. Purpose The aim of this study was to determine whether contemporary military load carriage is a source of injuries to Australian Regular Army soldiers and to profile these injuries. Methods The Australian Defence Force ‘Occupational Health, Safety and Compensation Analysis and Reporting’ database was searched to identify all reported injuries sustained during load carriage events. Key search terms were employed and narrative description fields were interrogated to increase data accuracy. Results A total of 1,954 injury records were extracted from the database. Of these, 404 injuries were attributed to load carriage. The majority of these load carriage injuries involved either the lower limb or back, with bones and joints accounting for the most frequently reported body structures to be injured. Field activities were the leading activities being performed at the time that load carriage injuries occurred, and muscular stress was identified as the mechanism of injury for over half of reported load carriage injuries. Conclusion This study suggests that load carriage is a substantial source of injury risk to Australian Army soldiers. Physical training may fail to adequately prepare soldiers for load carriage tasks during field training exercises.

Background Firefighting is a highly stressful occupation with unique physical challenges, apparel and environments that increase the potential for dehydration. Dehydration leaves the firefighter at risk of harm to their health, safety and performance. The purpose of this review was to critically analyse the current literature investigating the impact of fighting ‘live’ fires on firefighter hydration. Methods A systematic search was performed of four electronic databases for relevant published studies investigating the impact of live fire suppression on firefighter hydration. Study eligibility was assessed using strict inclusion and exclusion criteria. The included studies were critically appraised using the Downs and Black protocol and graded according to the Kennelly grading system. Results Ten studies met the eligibility criteria for this review. The average score for methodological quality was 55 %, ranging from 50 % (‘fair’ quality) to 61 % (‘good’ quality) with a ‘substantial agreement’ between raters (k = .772). Wildfire suppression was considered in five studies and structural fire suppression in five studies. Results varied across the studies, reflecting variations in outcome measures, hydration protocols and interventions. Three studies reported significant indicators of dehydration resulting from structural fire suppression, while two studies found mixed results, with some measures indicating dehydration and other measures an unchanged hydration status. Three studies found non-significant changes in hydration resulting from wildfire firefighting and two studies found significant improvements in markers of hydration. Ad libitum fluid intake was a common factor across the studies finding no, or less severe, dehydration. Conclusions The evidence confirms that structural and wildfire firefighting can cause dehydration. Ad libitum drinking may be sufficient to maintain hydration in many wildfire environments but possibly not during intense, longer duration, hot structural fire operations. Future high quality research better quantifying the effects of these influences on the degree of dehydration is required to inform policies and procedures that ensure firefighter health and safety.

Orr, RM, Ford, K, and Stierli, M. Implementation of an ability-based training program in police force recruits. J Strength Cond Res 30(10): 2781-2787, 2016-Currently, police recruit physical training programs generally use group-based runs of a "1 size fit all" approach. The aim of this study was to assess the impact of an ability-based training (ABT) program, as derived from the 30-15 Intermittent Fitness Assessment, on the metabolic fitness and injury rates of police recruits undergoing basic training. Police recruits completing two different stages of training (session 1: n = 54 and session 2: n = 233) were randomly assigned to either a control group (CG) (standard group running) or an intervention group (IG) (ABT program). Physical training was completed once a week over a 10-week period. Aerobic fitness was measured through 20-m progressive shuttle run test performance. Injury data were captured through formal accident and incident forms. Results found that aerobic fitness was maintained but not significantly improved in both groups for session 1, with no significant differences between the groups after training. In session 2, both groups significantly improved their aerobic fitness (p0.001), whereas the IG to a greater degree, with no significant differences between the groups after training. There were no significant differences in injury rates between groups (session 1: χ(1) = 1.533, p = 0.216; session 2: χ(1) = 1.252, p = 0.263). However, the IGs had a significantly lower relative risk (RR) of injury when compared with the CGs (group 1: RR = 0.31, p = 0.28; group 2: RR = 0.59, p = 0.24). The results suggest that coaches may benefit from implementing ABT programs in tactical populations and achieve the same or better fitness gains with a lower risk of injuring recruits.

Background: Rugby union is a collision-based ball sport played at the professional level internationally. Rugby union has one of the highest reported incidences of injury of all team sports. Purpose: To identify the characteristics, incidence, and severity of injuries occurring in Australian professional Super Rugby Union. Design: Descriptive epidemiology study. Methods: The present study was a prospective epidemiology study on a cohort of 180 professional players from 5 Australian Super Rugby teams during the 2014 Super Rugby Union Tournament. Team medical staff collected and submitted daily training and match-play injury data through a secure, web-based electronic platform. The injury data included the main anatomic location of the injury, specific anatomic structure of the injury, injury diagnosis, training or match injury occurrence, main player position, mechanism of injury, and the severity of the injury quantified based on the number of days lost from training and/or competition due to injury. Results: The total combined incidence rate for injury during training and match-play across all Australian Super Rugby Union teams was 6.96 per 1000 hours, with a mean injury severity of 37.45 days lost from training and competition. The match-play injury incidence rate was 66.07 per 1000 hours, with a mean severity of 39.80 days lost from training and competition. No significant differences were observed between forward- and back-playing positions for match or training injury incidence rate or severity. Conclusion: The incidence of injury for the present study was lower during match-play than has previously been reported in professional rugby union; however, the overall time loss was higher compared with previous studies in professional rugby union. The high overall time loss was due fundamentally to a high incidence of injuries with greater than 28 days’ severity.

This study analyzed the effects physical fitness may have on reasons for academy separation in law enforcement recruits. A retrospective analysis was conducted on 401 recruits, 330 recruits graduated (GRAD), and 71 recruits separated at various times during academy. Twenty-eight recruits separated for personal reasons (SEPPR), 18 due to physical training failures (i.e., poor fitness) or injury (SEPFI), and 25 due to academic or scenario failures (SEPAS). Fitness testing occurred prior to academy, and included: Push-ups and sit-ups in 60s, a 75-yard pursuit run (75PR), vertical jump, medicine ball throw, and multistage fitness test (MSFT). A one-way ANOVA with Bonferroni post hoc compared between-group fitness test performance. A multiple stepwise regression calculated whether recruit characteristics or fitness could predict separation. The GRAD group was younger than the SEPAS group (p &lt, 0.01), faster in the 75PR than the SEPFI group (p = 0.02), and completed more MSFT shuttles than the SEPPR and SEPFI groups (p = 0.01). Age predicted GRAD and SEPAS group inclusion, MSFT predicted GRAD, SEPPR, and SEPFI group inclusion. Recruits who had superior high-intensity running capacity (75PR) and aerobic fitness (MSFT) should have a better chance of completing academy. However, this could be influenced by training practices adopted during academy.

Tactical trainees, like those entering the police force, are required to undergo vigorous training as part of their occupational preparation. This training has the potential to cause injuries. In addition, the physical training, communal living and pressures of tactical training are known to induce immune suppression and have the potential to increase the risk of illness. The aim of this study was to investigate the relationship between leg power, as measured by a vertical jump (VJ), and rates of reported injuries and illnesses during police recruit training. Retrospective data from recruits (n = 1021) undergoing basic police recruit training at an Australian Police Force College was collected. Recruits completed a VJ assessment at the commencement of their second state of training. Formally reported illness and injuries were collected 12 weeks later, following completion of training. Correlations between VJ height and rates of reported illness and injury were low (r = −0.16 and −0.09, respectively) but significant (p < 0.005), with VJ height accounting for 2.6% and 0.8% of the variance in illness and injury rates, respectively. In terms of relative risks, recruits with the lowest recorded VJ heights were more than three times as likely as those with highest VJ heights to suffer injury and/or illness. Police recruits with lower VJ height are at a significantly greater risk of suffering an injury or illness during police basic recruit training.

Background Police officers are often required to undertake physically demanding tasks, like lifting, dragging and pursuing a suspect. Therefore, physical performance is a key requirement. Methods Retrospective data for 76 male police officers (mean age = 39.42 ± 8.41 years; mean weight = 84.21 ± 12.91 kg) was obtained. Data included anthropometric (skinfolds, estimated percentage body fat, lean body mass and fat mass) and physical performance (1 Repetition Maximum Bench Press, 1–min sit-ups, 1-min push-ups, vertical jump, 300 m run, 1.5 mile run) measures and correlations between anthropometric measurement and fitness score were obtained. Results Estimated percentage body fat was significantly (p ≤ .001) and negatively correlated with all performance measures, except sit-ups and 300 m and 1.5 mile run performance. Estimated lean body mass was significantly and positively (p ≤ .001) correlated with push-ups, bench press and vertical jump measures, while increasing estimated fat mass was significantly (p ≤ .001) associated with reduced performance on sit-up, vertical jump, 1.5 mile run and estimated maximal voluntary oxygen uptake. Conclusions A targeted approach, going beyond just decreasing percentage body fat to also selectively increasing lean mass, should be applied for optimal improvement in physical fitness performance.

The aim of this study was to determine whether poor movement patterns impact on police recruit task performance.Fifty-three volunteers were randomly selected from a pool of 173 police recruits attending basic recruit training. Relationships between movement performance, as measured by the Functional Movement Screen, and four occupational tasks were investigated.Eleven percent failed the marksmanship and baton strike assessments, 21% failed defensive tactics and 36% failed the tactical options assessment. Mean Functional Movement Screen score was 13.96 points (±1.99 points). Only the tactical options assessment approached a significant difference (p = 0.077) between pass/fail recruits. When Functional Movement Screen scores when graded as pass (14+) or fail (14) again only the tactical options assessment approached significance (p = 0.057).The results of this study suggest that a relationship between an officer's movement patterns and occupational performance, most notably choice of tactical options, may exist.

This study aimed to develop minimum standards for physical capability assessments (vertical jump, sit and reach, push-ups, seven-stage sit-ups, heaves, agility, 20-m shuttle run, loaded 5-km pack march, and 400-m swim) that candidates must pass before they can commence Australian Army Special Forces (SF) selection courses. Soldiers (Part A: n = 104; Part B: n = 92) completed the physical capability assessments before commencing a SF selection course. At the beginning of these selection courses, participants attempted two barrier assessments (3.2-km battle run and 20-km march). Statistical analysis revealed several physical capability assessments were associated with performance on the barrier assessments and selection course outcome (Part A); however, these statistical models were unable to correctly classify all candidates as likely to pass or fail the selection course. Alternatively, manual analysis identified a combination of physical capability standards that correctly classified 14% to 18% of candidates likely to fail, without excluding any candidates able to pass (Part A). The standards were applied and refined through Part B and included completing the 5-km pack march in ≤45:45 minutes : seconds, achieving ≥level five on the sit-up test, or completing ≥66 push-ups. Implementation of these standards may reduce attrition rates and enhance the efficiency of the SF recruitment process.

Due to the unpredictable, varied and often physical nature of law enforcement duties, police officers are at a high risk of work-related physical injury. The aim of this critical narrative review was to identify and synthesize key findings of studies that have investigated musculoskeletal injuries sustained by law enforcement officers during occupational tasks. A systematic search of four databases using key search terms was conducted to identify potentially relevant studies, which were assessed against key inclusion and exclusion criteria to determine studies to be included in the review. Included studies were critically appraised and the level of evidence determined. Relevant data were extracted, tabulated and synthesized. The 16 identified studies ranged in percentage quality scores from 25.00% to 65.00%, with a mean score of 41.25% and high interrater agreement in scores reflected in a Cohen’s Kappa coefficient, κ = 0.977. The most common body site of injury was the upper extremity, the most common injury types were soft-tissue sprains and strains and the most common cause of injury was a non-compliant offender, often involving assault. However, there was limited peer reviewed research in this area and the published research had a narrow focus and was of low to fair methodological quality.

Firefighters, along with other tactical personnel, are at a high risk of work-related physical injury above that of the private sector. The aim of this critical narrative review was to identify, critically appraise and synthesise key findings from recent literature investigating firefighting musculoskeletal injuries to inform injury reduction programs. The methodological approach (search terms, databases, etc.) was registered with PROSPERO and reported following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Study quality was assessed using the Downs and Black checklist with scores graded according to the Kennelly grading system. Levels of evidence were ranked according to the Australian National Health and Medical Research Council. Of the 8231 studies identified, 17 met the criteria for inclusion. The methodological quality of the studies was ‘fair’ with a level of evidence of III-2. Reported injury rates ranged from 9% to 74% with the lower extremities and back the leading aggregated bodily sites of injury. Sprains and strains were the leading nature of musculoskeletal injury, often caused by slips, trips and falls, although muscle bending, lifting and squatting or muscle stressing were also prevalent. This review may inform injury reduction strategies and given that injuries reported in firefighters are similar to those of other tactical populations, safety processes to mitigate injuries may be of benefit across the tactical spectrum.

Background Police officers are required to perform dynamic movements in unpredictable environments, the results of which can lead to injury. Early identification of poor movement patterns of a police population, and potential sub groups within this population, may provide opportunities to treat and minimise injury risks. The aim of this study was to profile the functional movement capabilities of an Australian state police force and potential sub groups through a retrospective cohort study. Methods Retrospective data from an Australian State Police Force were provided for analysis (♂ n = 1155, mean (±SD) age = 31.34 ± 8.41 years: ♀ n = 357, mean age = 27.99 ± 8.02 years). Data consisted of Functional Movement Screen (FMS) assessment results of male and female trainees and qualified police officers with all assessments conducted by a qualified Police Physical Training Instructor. Results Significantly higher (U = 253863, p

Aim: Undergraduate GPA (UGPA) is commonly used to select students into postgraduate physiotherapy programs. The aim of this study was to explore the relationships between UGPA and the academic and clinical performance of postgraduate entry-level physiotherapy students. Method: A retrospective cohort study of students from four cohorts (2010-2013) of a postgraduate entry-level physiotherapy program. UGPA, average pre-clinical coursework marks and clinical performance scores were investigated. Clinical performance was measured by the Assessment of Physiotherapy Practice. Normality tests, descriptive analysis and correlations between variables were calculated. Participants were then grouped according to UGPA and a one-way ANOVA was performed to determine differences in clinical or coursework performance between groups. Results: Data from 121 students were analysed. There were no significant relationships identified between UGPA and pre-clinical coursework or clinical performance scores. There were no significant differences in academic or clinical performance between groups when students were classified by UGPA. Conclusion: These findings indicate a need to reconsider the use of UGPA as a sole selection criterion and supports the inclusion of other criteria to select students into competitive programs. Minimum UGPA entry requirements for postgraduate physiotherapy programs should be reviewed to ensure all suitable applicants are eligible for admission.

Background With the removal of gender restrictions and the changing nature of warfare potentially increasing female soldier exposure to heavy military load carriage, the aim of this research was to determine relative risks and patterns of load carriage related injuries in female compared to male soldiers. Methods The Australian Defence Force Occupational Health, Safety and Compensation Analysis and Reporting workplace injury database was searched to identify all reported load carriage injuries. Using key search terms, the narrative description fields were used as the search medium to identify records of interest. Population estimates of the female: male incident rate ratio (IRR) were calculated with ninety-five percent confidence interval (95% CI) around the population estimate of each IRR determined. Results Female soldiers sustained 10% (n = 40) of the 401 reported injuries, with a female to male IRR of 1.02 (95% CI 0.74 to 1.41). The most common site of injury for both genders was the back (F: n = 11, 27%; M: n = 80, 22%), followed by the foot in female soldiers (n = 8, 20%) and the ankle (n = 60, 17%) in male soldiers. Fifteen percent (n = 6) of injuries in female soldiers and 6% (n = 23) of injuries in males were classified as Serious Personal Injuries (SPI) with the lower back the leading site for both genders (F: n = 3, 43%: M: n = 8, 29%). The injury risk ratio of SPI for female compared to male soldiers was 2.40 (95% CI 0.98 to 5.88). Conclusions While both genders similarly have the lower back as the leading site of injury while carrying load, female soldiers have more injuries to the foot as the second leading site of injury, as opposed to ankle injuries in males. The typically smaller statures of female soldiers may have predisposed them to their observed higher risk of suffering SPI while carrying loads.
