Abstract
ABSTRACT Schram, B, Orr, R, Niederberger, B, Givens, A, Bernards, J, and Kelly, KR. Cardiovascular demand differences between male and female US Marine recruits during progressive loaded hikes. J Strength Cond Res XX(X): 000-000, 2024-Despite having to carry the same occupational load, female soldiers tend to be lighter than male soldiers. The aim of this study was to determine the differences in cardiovascular load between female and male US Marine recruits during progressive load carriage hikes. United States Marine Corps recruits (565 male recruits; 364 female recruits) completed 6 loaded hikes over 6 weeks (1: 10 kg, 30 minutes; 2: 10 kg, 45 minutes; 3: 15 kg, 30 minutes, 4: 15 kg, 45 minutes; 5: 20 kg, 30 minutes; 6: 20 kg, 45 minutes) during which cardiovascular response was measured. Average heart rate (HRavg), HR maximum (HRmax), and pace were measured via a wrist-worn physiological monitor. Independent sample t-tests were conducted to compare between sexes, with significance set at 0.008 after adjusting for multiple comparisons. The average female recruit had significantly lower body mass (BM) compared with the average male recruit (p < 0.001) and thus carried a significantly heavier relative load. (10 kg ∼17%, 15 kg ∼25%, 20 kg ∼33%, p < 0.001). There were no significant differences in pace in any hike, and no significant differences were found in HRavg or HRmax when comparing female and male Marines during Hike 1. For female Marines, HRavg was significantly higher compared with male Marines during Hike 2 (+6.5 b·min-1, p < 0.001) and Hike 3 (+7.4 b·min-1, p < 0.001), and both HRavg and HRmax were significantly higher in Hike 4 (+11.9 b·min-1, +8.4 b·min-1, p < 0.001), Hike 5 (+7.7 b·min-1, +7.9 b·min-1, p < 0.001), and Hike 6 (+6.9 b·min-1, +7.1 b·min-1, p < 0.001), respectively. Female Marines endured greater cardiovascular demand compared with male Marines during load carriage events when carrying loads greater than 15 kg (∼25% BM).

Abstract
ABSTRACT Campbell, P, Maupin, D, Lockie, RG, Dawes, JJ, Simas, V, Canetti, E, Schram, B, and Orr, R. Evaluating the variability between 20-m multistage fitness test estimating equations in law enforcement recruits. J Strength Cond Res 38(4): 742-748, 2024-The 20-m multistage fitness test (20MSFT) is commonly used by law enforcement agencies to measure aerobic fitness and to estimate maximal aerobic consumption (V̇ o2 max). These measures are an important occupational variable with aerobic fitness levels linked to employment status, occupational performance, and long-term health in law enforcement officers. There are a multitude of predictive equations used to provide an estimate of V̇ o2 max, with the extent of variability in the estimated V̇ o2 max currently unknown in this population. This has consequences for comparisons between, and across, differing agencies, and in capabilities of deriving normative data. The aim of this investigation was to compare the variability in estimated V̇ o2 max scores derived from different 20MSFT predictive equations. The 20-m multistage fitness test data from 1,094 law enforcement recruits (male n = 741, 25.2 ± 6.3 years; female: n = 353, 25.6 ± 5.6 years) from a single agency were retrospectively analyzed. The 20MSFT scores were transformed into estimated V̇ o2 max scores using 6 different predictive equations. Significance was set at p < 0.05. Results demonstrated significantly different V̇ o2 max scores between each predictive equation ( p < 0.001; d = 0.25-1.53) and between male and female recruits ( p < 0.001, r = 0.55). All estimated V̇ o2 max equations showed small to very strong correlations with each other ( p < 0.001; r = 0.32-0.99). The findings indicate considerable dispersion of V̇ o2 max scores when using differing equations, suggesting raw 20MSFT variables (e.g., shuttles or distance completed) should be preferred to measure and apply results from aerobic fitness tests if standardized approaches are not developed within law enforcement.

Abstract
ABSTRACT Campbell, P, Maupin, D, Lockie, RG, Dawes, JJ, Simas, V, Canetti, E, Schram, B, and Orr, R. Determining the changes in law enforcement recruit aerobic fitness using the 2.4-km run and 20-m multistage fitness test. Does the type of test matter? J Strength Cond Res XX(X): 000-000, 2023-Aerobic fitness is linked with academy graduation, employment, and the long-term health of law enforcement officers and is often used as a training outcome. However, different tests can be used, and aerobic improvements may differ according to the test used. The aim of this study was to determine whether recruits improved to a greater extent in 1 aerobic test compared with the other. Retrospective data from 5 law enforcement recruit cohorts (males = 741; females = 353) who underwent 18 weeks of academy training were analyzed. Initial 20-m multistage fitness test (20MSFT) and 2.4-km run assessments were completed during weeks 4 and 5 of training, with final testing completed during weeks 16 and 17, respectively. A repeated-measures analysis of variance (p < 0.05) with a Bonferroni post hoc analysis determined changes in aerobic fitness in the 20MSFT and 2.4-km run between male and female recruits. A mean difference of 9.27 (95% confidence intervals [CI] 14.8-10.9; d = 0.63; p < 0.001) shuttle increase in 20MSFT performance and 20.1 (95% CI 16.0-24.2; d = 0.49; p < 0.001) second improvement in 2.4-km run time were demonstrated when averaged across sex, yielding a larger performance improvement for the 20MSFT compared with the 2.4-km run. Conversely, there was a smaller magnitude of change in aerobic fitness between male recruits and female recruits for the 20MSFT (d = 0.47) compared with the 2.4-km run (d = 0.50). The findings indicate that current academy training results in improvements to aerobic fitness and to a greater magnitude in the 20MSFT compared with the 2.4-km run. These results may affect policy considerations for law enforcement agencies regarding aerobic test selection.

Abstract
Damage to the articular cartilage resulting in an acute tear can lead to functional changes within the joint and increase the risk of osteoarthritis developing. There is limited understanding of the association between occupational risk factors and sustaining an acute articular cartilage tear in the military and other physically demanding occupations. Therefore, the aim of this systematic review was to identify and evaluate original research reporting on occupational risk factors associated with sustaining acute articular cartilage tears. METHODS A systematic review following the Preferred Reporting Items for Systematic review and Meta-Analysis-Protocols was conducted and registered with the Open Science Framework. Key academic databases were searched using terms from the following concepts: risk or cause, paid occupations, and acute articular cartilage tears. RESULTS Of an initial 941 studies, 2 studies met the eligibility criteria, both reporting data from military contexts; only one evaluated acute articular cartilage tears in both males and females. One paper focused on articular cartilage injury within the knee and the other within the ankle joint with incidence rates being 0.2 and 0.3 per 1000 person-years, respectively. People in more physically active occupations and individuals with an above-normal body mass index were reported as being at higher risk of sustaining an acute articular cartilage tear. CONCLUSION Physically demanding occupations, such as the military, may increase the risk for acute tears of the articular cartilage. However, the findings of this review indicate there is a paucity of research to underpin understanding of the injury mechanisms and occupational risk factors for acute articular cartilage tears.

Abstract
This study aimed to identify the most important, frequently performed, and physically demanding tasks performed by Brazilian firefighters and to identify tasks that could be used to assess physical fitness. A subjective task analysis was conducted. Five hundred twenty-four firefighters (84% male; 16% females) responded to an online survey and rated 37 tasks across three domains (most important, most frequent, and most physically demanding). A dichotomous decision analysis was used to inform the proposed physical fitness tests. Wildland firefighting tasks presented the highest overall mean rate. Traffic control was considered the most important and frequently performed task. Lifeguard rescue was considered the most physically demanding task. The dichotomous analysis identified 14 essential tasks (seven structural firefighting and seven automobile accidents). The tasks identified may be helpful in developing criterion physical fitness tests and training programs related to firefighters' demands.Practitioner summary: The unpredictability, variability, and dangerousness of firefighting make it challenging to observe the physical demands imposed on firefighters. A subjective task analysis was conducted to identify essential tasks performed by Brazilian firefighters. Wildland firefighting, lifeguard rescue, automobile accidents, and structural firefighting tasks were the most important, frequent, and physically demanding.

Abstract
BACKGROUND Police Tactical Groups (PTGs) are specialist police units tasked with rigorous physical and psychosocial duties. Consequently, selection courses (SCs) for service in these units must also be rigorous. Given the intensity of SCs, holistic monitoring for potential overstress may be beneficial. Heart Rate Variability (HRV) is one holistic stress measure that can be obtained in austere environments. OBJECTIVE The purpose of this study was to profile HRV during a PTG SC. Six (n = 6) qualified male police officers attempted a 36-hour PTG selection course held at an Australian state facility. METHODS HRV was obtained from Equivitaltrademark EQ02 + LifeMonitor bioharnesses. The selection course consisted of physically demanding events with minimal sleep (approx. 45 mins). Only one candidate completed the full selection course; whose results are reported here. RESULTS A visual time-series of 384 consecutive 5 min HRV analyses was generated. Contextual analysis was applied to appreciate HRV changes between SC serials. HRV decline occurred during the planning of a navigation exercise and a pack march. Increases in HRV were observed throughout the pack march exercise and rest period. CONCLUSION This case study demonstrates the potential utility for selection personnel to obtain additional insight into candidate responses to various occupational challenges throughout an SC. Information provided by HRV monitoring may support leadership decisions when evaluating personnel holistically. For example, the ability to continue occupational task execution even while experiencing potential overstress (as measured by HRV) and after food and sleep deprivation is desirable. HRV may potentially inform stakeholders regarding overstress in PTG candidates.

Abstract
BACKGROUND Load carriage tasks during United States Marine Corps (USMC) recruit training can cause injury. Load carriage conditioning, if optimized, can reduce injury risk. OBJECTIVE To compare injuries sustained by USMC recruits following participation in either the Original Load Carriage (OLC) program or a Modified Load Carriage (MLC) program. METHODS Retrospective musculoskeletal injury data were drawn from the USMC San Diego Sports Medicine injury database for recruits completing the OLC (n = 2,363) and MLC (n = 681) programs. Data were expressed as descriptive statistics and a population estimate of the OLC:MLC relative risk ratio (RR) was calculated. RESULTS The proportion of injuries sustained in the MLC cohort (n = 268; 39% : OLC cohort, n = 1,372 : 58%) was lower, as was the RR (0.68, 95% CI 0.61- 0.75). The leading nature of injury for both cohorts was sprains and strains (OLC n = 396, 29%; MLC n = 66; 25%). Stress reactions were proportionally higher in MLC (n = 17, 6%; OLC n = 4, 0.3%), while stress fractures were proportionately lower (MLC n = 9, 3%; OLC n = 114, 8%). Overuse injuries were lower in MLC (- 7%). The knee, lower leg, ankle, and foot were the top four bodily sites of injuries and the Small Unit Leadership Evaluation (SULE), Crucible, overuse-nonspecific, running, and conditioning hikes were within the top five most common events causing injury. The prevalence rates of moderate severity injury were similar (MLC = 23%; OLC = 24%), although MLC presented both a higher proportion and prevalence of severe injuries (MLC = 6%; OLC = 3%, respectively). CONCLUSION A periodized load carriage program concurrently increased exposure to load carriage hikes while reducing injuries both during the load carriage hikes and overall.

Abstract
BACKGROUND Within individual policing organisations, there are a wide variety of units and job roles. OBJECTIVE To profile the occupational tasks performed by Australian mounted police officers, aiming to offer conditioning insight into this unique job role. METHODS Thirteen fully qualified and operational mounted police officers (n = 11 females), who served in the mounted police unit for ∼3.3 (±2.3) years, participated in this observational cohort study. Participants completed a survey outlining common occupational tasks and were monitored throughout four consecutive shifts. Participants' heart rate (HR), respiratory rate (RR), and skin temperature (ST) data were collected via wearable monitoring (Equivital EQ-02, Hidalgo, UK) and body position, physical activity undertaken, task effort, and load carriage were recorded by researchers. A one-way ANOVA was used to assess mean differences in physiological measures between the three most reported tasks. RESULTS Survey identified 130 tasks, with 38 listed as most common. The three most reported mounted police tasks were: 'horse riding' (n = 13, 34%), 'mounted patrols' (n = 10, 26%), and 'horse care' (n = 10, 26%). These were also reported as the most physically demanding. HR during 'horse care' and 'horse riding' were significantly higher than when 'mounted patrolling' (27±7bpm, p = 0.001 and 33±8bpm; p = 0.001, respectively). Mean RR was higher when 'horse riding' when compared to 'horse care' (5.3±1.6brpm) and 'mounted patrol' (8.5±1.9brpm). CONCLUSION Mounted police officers experience unique physiological challenges throughout their routine occupational tasks. This study highlights the significance of understanding occupation-specific tasks and stressors undertaken by mounted police to develop relevant conditioning, rehabilitation, and monitoring procedures.

Abstract
BACKGROUND Concerns are sometimes raised by police applicants undertaking physical fitness testing that they were unfamiliar with the test requirements which in turn negatively impacted their performance. OBJECTIVE The aim of this study was to investigate the effects of a single day physical test training session on physical fitness scores of police candidates. METHODS The sample consisted of female police candidates (n = 133) who attended a pre-academy training session. On the first day of pre-training, candidates' physical fitness was measured following official assessment day protocols. Measures included maximal handgrip strength, number of push-ups in 10 sec (PU), number of sit-ups in 30 sec (SU), standing long jump (SLJ), Abalakow jump test (AJ), 12 min Cooper running test (CT), and a motor educability test (ME). After the assessment, the overseeing UCIPS staff provided a detailed test skills briefing to candidates (e.g., common mistakes made during testing, how test performance could be improved, etc.). Immediately after the briefing, candidates performed the tests once again. Differences between results were measured using a paired samples t-test with significance set at 0.05. RESULTS Paired sample t-tests determined significant (p < 0.001), large (Rank-Biserial Correlation = 1.00), improvements in physical fitness scores during the second assessment following familiarisation and feedback on test performance. CONCLUSION Pre-academy training may be effective in improving candidates' physical fitness scores, in most tests, prior to the official assessment for the enrolment to police studies. Thus, to optimise initial candidate scores and opportunities for successful enlistment, police agencies may benefit from providing pre-assessment training.

Abstract
Fatigue in emergency first responders (EFRs) is known to affect performance abilities and safety outcomes for both patients and EFRs. The primary aim of this review was to determine the main contributors to occupation-induced fatigue in EFRs and its subsequent impacts. Following the PRIMSA checklist, academic databases (Medline, Embase, CINAHL, and SPORTDiscus) were searched using key terms with results subjected to inclusion and exclusion criteria. Populations of interest were firefighters, paramedics, or emergency call centre personnel. Of the 5633 records identified, 43 studies, which reported on 186 unique measures from a total population of 6373 participants, informed the review. Synthesis revealed fatigue was caused by lack of sleep during the shift and consistent poor sleep quality which negatively impacted cognitive function, alertness, and physical and mental health while increasing safety-compromising behaviours and injuries. Both subjective and objective assessments of fatigue are necessary for effective risk management in EFRs. EFRs that are consistently fatigued are at a greater risk of poor physical and mental health, reduced cognitive function, and increased injuries. No studies reported on fatigue in emergency call centre personnel, highlighting a literature gap. Funding was provided by the Australian Capital Territory Emergency Services Agency. Preregistration was filed in OSF: osf.io/26f3s.

Abstract
BACKGROUND Genitourinary infections, including those associated with the urinary tract (urinary tract infection [UTI]) and vulvovaginal region, are common in women, affecting approximately one-third of biological females. A growing female military workforce necessitates consideration of their genitourinary health risks and needs to support and enhance their occupational health, safety, and performance. METHOD The pelvic health of active-duty servicewomen in the Australian Defense Force (ADF) was explored using an online cross-sectional survey. For the purposes of this study, only data related to genitourinary infections were extracted. The data were descriptively analysed to provide estimates of period prevalence rates. Risk factors and prevention and management strategies utilized were identified and described. RESULTS Of the 491 servicewomen who provided survey responses, 41% (95% confidence interval [CI]: 37%-46%) reported experiencing at least one UTI and 32% (95% CI: 28%-36%) reported experiencing regular symptoms of vulvovaginal irritation during their last period of active-duty service. Service arm, length of service, and history of participation in field activities or deployment were not substantially associated with prevalence estimates. Medical assessment was the most common diagnostic strategy for UTI and antibiotics were the most common management strategy. CONCLUSION Genitourinary infections are common in female ADF personnel and may impact on occupational health and performance. Therefore, organization-wide prevention and management approaches may be an important strategy for reducing the impact on personnel, their units and mission objectives, by reducing working days lost, utilization of health services and minimizing risks in more austere military environments.

Abstract
Police tactical group (PTG) personnel are exposed to physical, mental, and emotional stressors. Consequently, PTG selection courses (SCs) impart similar challenges, often resulting in candidate attrition. Holistic assessment may provide additional support to stakeholders given these risks. Heart Rate Variability (HRV) is an objective holistic stress measure that may be applicable in PTG SCs but has not been thoroughly researched. Therefore, this study aimed to report HRV data in an end-user accessible format and determine the relationship between HRV and attrition. A total of 18 qualified Australian State law enforcement officers completed a 1-day physical readiness assessment. Of those, six males progressed to an additional two-day course, on which this study is focused. This two-day selection consisted of additional physical challenges and occupational assessments. HRV was obtained from 2-lead ECGs and defined as the percentage of R-R intervals that varied by ≥50 ms (pRR50). Data were summarized in a heat map of consecutive short-term analyses. Three candidates withdrew. A logistic regression based on heat map data found high HRV was significant for predicting attrition, χ2 (6) = 8.318, p = 0.004. HRV may provide insight for PTG stakeholders monitoring attrition. While the sample size was limited and replication is needed, this study tentatively establishes value for HRV monitoring in PTG SCs.

Abstract
Persons working in tactical occupations are often exposed to high-stress situations. If this stress is to be measured, an understanding of the stress outcomes used in these occupations is needed. The aim of this review was to capture and critically appraise research investigating subjective and objective outcome measures of physiological stress in tactical occupations. Several literature databases (PubMed, EMBASE, EBsco) were searched using key search words and terms. Studies meeting inclusion criteria were critically evaluated and scored by two authors using the Joanne Briggs Institute (JBI) critical appraisal tool. Of 17,171 articles, 42 studies were retained. The Cohen's Kappa agreement between authors was 0.829 with a mean JBI Score of included studies of 8.1/9 ± 0.37 points. Multiple subjective and objective measures were assessed during a variety of high-stress tasks and environments across different occupations, including police officers, emergency service personnel, firefighters, and soldiers in the military. Common objective outcomes measures were heart rate, cortisol, and body temperature, and subjective measures were ratings of perceived exertion, and the Self Trait Anxiety Inventory. Often used in combination (i.e., subjective and objective), these outcome measures can be used to monitor stressors faced by tactical personnel undergoing on-the-job training.

Abstract
INTRODUCTION AND HYPOTHESIS Lower urinary tract symptoms (LUTS) are common in the general female population. It was hypothesised that Australian female military personnel and veterans would experience similar types and prevalence of LUTS as the broader Australian female population. METHODS An online cross-sectional survey was utilised to explore the pelvic health of active servicewomen and veterans in the Australian Defence Force (ADF). For the purposes of this report, only the demographic and LUTS data (excluding urinary tract infections) were extracted and descriptively analysed. RESULTS A total of 491 complete survey responses were received and analysed. Respondent characteristics were comparable to those documented in a departmental report regarding ADF servicewomen. No LUTS were reported by 38% of respondents. Regular symptoms of urinary incontinence were experienced by 27% of respondents (stress urinary incontinence = 23%, urge urinary incontinence = 16%, mixed urinary incontinence = 13%), bladder storage issues by 20-27%, and various voiding impairments by 9-27%. In addition, 41% reported regularly experiencing two or more LUTS, and for over two thirds of respondents, LUTS were an ongoing issue. Relationships between age, parity, and symptoms of urinary incontinence were also seen. CONCLUSIONS Consistent with wider research in Australian female populations, LUTS were commonly experienced during service by ADF female military personnel and veterans. Given the high likelihood of female military personnel experiencing LUTS during their service, and a proportion experiencing ongoing symptoms, tailored monitoring and support for urinary health should be available to enhance occupational health, safety, and performance.

Abstract
OBJECTIVES Emergency department (ED) teams frequently perform under conditions of high stress. Stress exposure simulation (SES) is specifically designed to train recognition and management of stress responses under these conditions. Current approaches to design and delivery of SES in emergency medicine are based on principles derived from other contexts and from anecdotal experience. However, the optimal design and delivery of SES in emergency medicine are not known. We aimed to explore participant experience to inform our approach. METHODS We performed an exploratory study in our Australian ED with doctors and nurses participating in SES sessions. We used a three-part framework-sources of stress, the impacts of that stress, and the strategies to mitigate-to inform our SES design and delivery and to guide our exploration of participant experience. Data were collected through a narrative survey and participant interviews and analyzed thematically. RESULTS There were 23 total participants (doctors n = 12, nurses n = 11) across the three sessions. Sixteen survey responses and eight interview transcripts were analyzed, each with equal numbers of doctors and nurses. Five themes were identified in data analysis: (1) experience of stress, (2) managing stress, (3) design and delivery of SES, (4) learning conversations, and (5) transfer to practice. CONCLUSIONS We suggest that design and delivery of SES should follow health care simulation best practice, with stress adequately induced by authentic clinical scenarios and to avoid trickery or adding extraneous cognitive load. Facilitators leading learning conversations in SES sessions should develop a deep understanding of stress and emotional activation and focus on team-based strategies to mitigate harmful impacts of stress on performance.

Abstract
ABSTRACT Kukić, F, Janković, R, Dawes, JJ, Orr, R, and Koropanovski, N. Effects of occupational load on the acceleration, change of direction speed, and anaerobic power of police officers. J Strength Cond Res XX(X): 000-000, 2022-Police officers engage in movements such as foot pursuits, sudden directional changes, or prolonged sprinting while wearing occupational loads (including body armor, baton, radio, handcuffs, and sidearm). This study investigated the effects of incrementally heavier loads carried by police students on their physical performance. Police students (n = 63; male n = 39 male and 24 female students) performed an acceleration over a 10-m distance (Acc10m), Illinois agility test (IAT), and 300-yard shuttle run test (ShR300y) without load, with a 5-kg load (handgun, spare empty magazine, baton, and handcuffs), and with a 10-kg load (loaded vest). The effects of different load conditions were investigated for both sexes using a repeated-measure analysis of variance and Cohen's effect size. Female students carried relatively heavier loads and were slower than male students in Acc10m, IAT, and ShR300y. Load significantly (p < 0.001) impaired the performance in Acc10m, IAT, and ShR300y in both sexes, but the effects were greater (p < 0.001) among female police students. A load as little as 5 kg was sufficient to reduce Acc10m, IAT, and ShR300y among police students. Increasing the load to 10 kg (i.e., wearing the body armor) did not significantly affect Acc10m and IAT among male students, but it did affect Acc10m and IAT among female students. Sprint endurance (i.e., ShR300y) was strongly affected by both loads regardless of sex. Strength and conditioning programs should focus on strength, power, and anaerobic endurance to improve performance while carrying occupational loads. Occasional training with loads similar to those at work may further ensure that officers are fit for purpose.

Abstract
Mounted police officers are subject to unique occupational tasks which may lead to unique injuries. This study's aim was to describe policing injuries suffered by mounted police officers contextualized through comparison to non-mounted officers. Injury data from 01 July 2014 to 30 June 2020 were provided from a state policing agency's incident reporting database. The data reported the numbers and rates of injuries and classified the injuries by gender, cause, mechanism, nature, and hours worked. Of the 35,406 reported injuries, 35,255 (99.6%) injuries were reported by non-mounted police officers. An annual incidence rate of 338-364 and 626-952 injuries per 1000 personnel were reported in non-mounted and mounted police, respectively. For mounted police, the leading causes of injuries were slips, trips, and falls (23.8%), followed by repetitive tasks and movements (9.9%). Physical assault was the leading cause of injury for non-mounted police officers (21.3%), followed by slips, trips, and falls (16.0%). In mounted police, falls from heights (15.9%) and repetitive tasks and movements (10.6%) comprised the most frequently specified mechanisms of injury, as compared to physical assault (21.0%) and physical exercise (5.2%) in non-mounted police. The most common activities being performed at the time of injury for mounted police were animal handling (64.9%) as opposed to arresting an offender (31.2%) for non-mounted police. Sprains and strains and bruises and swelling were the leading natures of injuries among both mounted (44.4% and 29.1%, respectively) and non-mounted (36.6% and 21.2%, respectively) officers. The leading body sites of injury in mounted officers were the lower back (13.9%) and neck and shoulders (7.3% each), and for non-mounted police, the knee (13.9%), lower back (10.0%), and hand (8.2%) were the most common. Mounted police officers sustained injuries through different activities, causes, and mechanisms and to different body sites at 2-3 times higher incidence rates. Mounted police officers warrant specifically tailored injury mitigation and return-to-work strategies.

Abstract
Specialist police tactical groups (PTGs) are involved in situations that extend beyond the capability of general duties police and can include responding to active shooter incidents. Due to the nature of their tasks, these officers typically carry and wear additional equipment which can impart an increased physical cost, for which the officers must be prepared. The aim of this study was to examine the heart rate responses and movement speeds of specialist PTG officers during a multistorey active shooter scenario. Eight PTG officers completed an active shooter scenario within a multistorey office building district whereby they were required to carry and wear their usual occupational personal protection equipment (average load = 16.25 ± 1.39 kg) while clearing high-risk environments and locating an active threat. Heart rates (HR) and movement speeds were all recorded via HR and global positioning system monitors. Average PTG officer HR over the duration (19.14 ± 0.70 minutes) was 165 ± 6.93 bpm (89 ± 4% age predicted heart rate maximum (APHRmax)) with 50% of the scenario performed at intensities between 90-100% APHRmax. Around 75% of the scenario had the officers moving at speeds of between 3-6.99 kilometers per hour (km/h), although speeds of 7-10.99 km/h were not uncommon. Understanding the responses of specialist officers during a multistory active shooter scenario may help in designing specific strength and conditioning programs to meet this potential scenario demand.

Abstract
Background An effective military force is required to be agile, capable, efficient, and potent. Injuries to military personnel interrupt active-duty service and can detract from overall capability. These injuries are associated with a high individual and organizational burden, with lost work time and financial costs—all problematic for the ongoing functioning of a military force. Injury control strategies have therefore been described as force multipliers. Female personnel form an integral part of any modern defence force, but little research has examined their specific experiences of injury, to inform targeted injury control efforts. The aim of this review was to identify and synthesise findings from studies of injury rates and patterns in female military personnel, comparing them to those of male personnel. Methods A systematic search was conducted for studies which compared injury rates between the sexes at any stage of military service, from basic training through to deployment. Databases searched included PUBMED, CINAHL and Medline through OVID. Methodological quality of eligible articles was assessed using the Critical Appraisal Skills Program (CASP), and AXIS tools and data were extracted, synthesized, and, where possible, underwent meta-analysis. Results Of 2287 identified studies, a total of 25 studies were eligible and included. Methodological quality ranged from 60% up to a perfect score of 100%, with an average of 82% across all studies. Relative risks for injuries (reported as RR [95%CI]) to females when compared to males were 2.10 [1.89–2.33] during basic training, 1.70 [1.33–2.17] during officer training, and 1.23 [1.05–1.43] post initial training. After adjustment for differences between the sexes in average fitness levels (2-mile run time), there was no longer a significant difference in injury rates (adjusted RR: 0.95 [0.86–1.05]). Female personnel tended to make bigger improvements in their fitness during basic training than males and tended to report their injuries more frequently and sooner than males. Conclusion While this review found a higher rate of reported injuries in female military personnel when compared to male personnel, differences between the sexes in average fitness levels and injury reporting behaviours may largely explain this rate difference. The difference in rates of reported injuries was greatest during basic training, and reduced thereafter, possibly due in part to a reduced difference in fitness between the sexes or increased opportunity to self-determine workloads relative to fitness levels.

Abstract
Law enforcement officers routinely face unpredictable scenarios that may threaten the public, their colleagues, or themselves. In such situations, officers may be required to use firearms, with shooting accuracy becoming crucial. This literature review aimed to identify, synthesize, and report on research investigating factors that affect marksmanship in law enforcement personnel. A systematic search of seven databases was undertaken following the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) approach. From an initial 5396 identified studies, 23 met the eligibility criteria. The key findings from these papers were: (1) physical exertion does not appear to decrease shooting performance, especially at close range (<10 m); (2) tactical load carriage does not appear to decrease shooting performance; in fact, it has been reported by officers as improving performance (likely due to training specificity); (3) the physical capability of officers may be of importance, notably grip strength, which the volume of evidence suggests is positively correlated with marksmanship; (4) anxiety imparted through high-stress scenarios negatively impacts shooting performance, but training under stress may counteract this factor, albeit for a short period. Together, these factors appear to have a trainability component where increased specific and realistic training can improve shooting accuracy, time, and precision, especially in high-stress situations.

Abstract
The risks and incidence rates of musculoskeletal injuries among military personnel are high, and the importance of physiotherapy in treating these injuries is well established. However, what is less clear is whether the timing of commencement of physiotherapy treatment affects musculoskeletal injury outcomes in military personnel. This lack of clarity is exacerbated by the known underreporting of injuries among military personnel, and the resulting self-management of musculoskeletal injuries using analgesics, non-steroidal anti-inflammatories and other means. This narrative review was designed to identify and synthesize current evidence regarding the effects of timing of physiotherapy treatment on musculoskeletal injury outcomes, focusing on potential benefits of early versus typical or delayed commencement of physiotherapy treatment. Overall, current evidence suggests early physiotherapy treatment of musculoskeletal injuries offers distinct advantages over typical or delayed commencement of physiotherapy treatment in military settings. Specifically, it appears early treatment expedites recovery in early phases following injury onset and benefits longer term mental health and well-being. It may also reduce the need for more invasive and costly health care interventions and enable earlier return to training and operational service. Importantly, a cultural shift within military contexts to ensure early reporting of musculoskeletal injuries is required if the benefits of early commencement of physiotherapy treatment are to be achieved.

Abstract
The aim of this scoping review was to investigate the impact of footwear on worker physical task performance and injury risk. The review was guided by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews protocol and registered in the Open Science Framework. Key search terms were entered into five academic databases. Following a dedicated screening process and critical appraisal, data from the final articles informing this review were extracted, tabulated, and synthesised. Of 19,614 identified articles, 50 articles informed this review. Representing 16 countries, the most common populations investigated were military and firefighter populations, but a wide range of general occupations (e.g., shipping, mining, hairdressing, and healthcare workers) were represented. Footwear types included work safety boots/shoes (e.g., industrial, gumboots, steel capped, etc.), military and firefighter boots, sports shoes (trainers, tennis, basketball, etc.) and various other types (e.g., sandals, etc.). Occupational footwear was found to impact gait and angular velocities, joint ranges of motion, posture and balance, physiological measures (like aerobic capacity, heart rates, temperatures, etc.), muscle activity, and selected occupational tasks. Occupational footwear associated with injuries included boots, conventional running shoes, shoes with inserts, harder/stiffer outsoles or thin soles, and shoes with low comfort scores-although the findings were mixed. Occupational footwear was also linked to potentially causing injuries directly (e.g., musculoskeletal injuries) as well as leading to mechanisms associated with causing injuries (like tripping and slipping).

Abstract
Several occupations require workers to spend long periods of time driving road vehicles. This occupational task is associated with musculoskeletal disorders. The purpose of this review was to collate, synthesize, and analyze research reporting on musculoskeletal disorders associated with occupational driving, in order to develop a volume of evidence to inform occupational disorder mitigation strategies. A systematic search of academic databases (PubMed, EBSCO host, CINAHL, SPORTDiscus, and Web of Science) was performed using key search terms. Eligible studies were critically appraised using the Joanna Briggs Institute critical appraisal checklists. A Cohen’s kappa analysis was used to determine interrater agreement between appraisers. Of the 18,254 identified studies, 25 studies were selected and appraised. The mean critical appraisal score is 69% (range 38–100%), with a fair level of agreement (k = 0.332). The studies report that musculoskeletal disorders, most commonly lower back pain, is of concern in this population, particularly in truck, bus, and taxi drivers. Risk factors for these occupations include long hours in a sitting position, years in the profession, vehicle ergonomics, and vibration.

Abstract
Introduction Female soldiers comprise an important component of any modern army, yet little research has been performed to investigate differences in the profiles of injuries reported by qualified female and male army personnel. Aim The aim of this study was to compare injury rates and patterns between female and male soldiers of the Australian Regular Army (ARA). Methods Data pertaining to all injuries reported by ARA members over a two-year period were accessed from the SENTINEL database and analysed descriptively. Findings regarding injury patterns were reported by most common location, nature, mechanism, and activity being performed at the time of injury. Injury incidence rates (IR) were calculated based on population size, and injury incidence rate ratios (IRR) comparing female and male injury rates were determined. Results A total of 8750 injuries were recorded across the two-year time period (2018–2020) of the study (minor injuries: n = 1766 female, n = 6870 male; serious injuries: n = 19 female, n = 95 male). Higher incidence rates of minor injuries were reported for female soldiers (IR = 20.75 injuries/100 soldiers/year) when compared to male soldiers (IR = 13.60 injuries/100 soldiers/year), with an IRR of 1.53 [95% CI = 1.46–1.60]. More serious injuries were reported at a similar rate between female (IR = 0.22/100 soldiers/year) and male soldiers (IR = 0.21/100 soldiers/year), with an IRR of 1.05 [95% CI = 0.65–1.72]. Female soldiers tended to report more ankle injuries than male soldiers who reported more knee injuries. Physical training and combat training were the most common causes of injury for both sexes. Discussion There were subtle differences in body locations of minor injuries within female and male soldiers. Both minor and more serious injury profiles were otherwise similar between sexes. Therefore, strategies required to minimise injuries in female soldiers may be similar in many respects to strategies required for male soldiers but require some differences to account for the subtle differences in body locations of injury, and so to ensure effectiveness across all personnel.

Abstract
To investigate the effect of a Trunk Training (TT) program on the general musculoskeletal pain (GMP) and physical performance of Military Police Officers. Twenty officers were divided into either control group (CG) or TT group (TTG). Both groups performed nine weeks of traditional physical training. However, the TTG had 25-minutes allocated to TT during each scheduled physical training period. Anthropometric, trunk endurance, and physical fitness tests were completed pre- and post-training for both groups. Both groups also answered a weekly questionnaire about their GMP. Post-training, trunk endurance performance was significantly higher (p < 0.05) and the GMP significantly lower (p < 0.05) in the TTG when compared to the CG. Improvement in side plank test scores was associated with a decreased in GMP (r = -0.495, p < 0.05). TT can reduce the perception of GMP in addition to increasing the endurance of the trunk muscles. The side plank was the only physical test associated with GMP. Practitioner summary: Trunk Training can reduce general musculoskeletal pain and increase the endurance of the trunk muscles without a concomitant loss in general fitness in elite Military Police Officers. This research lasted 11 weeks and presents real-world and pragmatic findings.

Abstract
A fracture, being an acquired rupture or break of the bone, is a significant and debilitating injury commonly seen among athletes and military personnel. Stress fractures, which have a repetitive stress aetiology, are highly prevalent among military populations, especially those undergoing training. The primary aim of this review is to identify non-modifiable risk factors for stress fractures in military personnel undergoing training. A systematic search was conducted of three major databases to identify studies that explored risk factors for stress fractures in military trainees. Critical appraisal, data extraction, and a narrative synthesis were conducted. Sixteen articles met the eligibility criteria for the study. Key non-modifiable risk factors identified were prior stress fracture and menstrual dysfunction, while advancing age and race other than black race may be a risk factor. To reduce the incidence of stress fractures in military trainees, mitigating modifiable risk factors among individuals with non-modifiable risk factors (e.g., optimising conditioning for older trainees) or better accommodating non-modifiable factors (for example, extending training periods and reducing intensity to facilitate recovery and adaptation) are suggested, with focus on groups at increased risk identified in this review.

Abstract
UNLABELLED Police trainees undergoing training to prepare them for the occupational demands of policing are often subjected to fitness testing. The aim of this review was to critically appraise research studies employing police fitness tests. METHOD A comprehensive search of four databases (PubMed, EMBASE, and Ebscohost [CINAHL and SportDiscus]) was conducted by two authors independently. After duplicate articles were removed, articles that did not meet the pre-determined inclusion criteria and met the exclusion criteria were removed. The remaining studies were critically appraised by two authors independently using a Downs and Black Checklist. Cohen's Kappa coefficient was used to measure the level of agreement between appraisers and calculated by a third author. The grading system proposed by Kennelly was used to grade the methodological quality of the studies. RESULTS From an initial 7384 identified studies, including four from additional sources, 11 studies met the criteria for review. The mean critical appraisal score for the articles was 74.36 (± 1.48%) being considered 'good' quality and a 'substantial' level of agreement was found between the two appraisers (k = 0.75). The most common measures assessed were muscle endurance (push-ups and sit-ups) and aerobic capacity (running), with the least common measure being agility. Assessments of push-ups and the 2.4-km (1.5-mile) run had the strongest correlations to law enforcement academy graduation across the studies. Grip strength may predict occupational performance (marksmanship) as well as longevity. CONCLUSION The push-up and 2.4 km (1.5-mile) run fitness tests were the most popular fitness assessments and had the strongest positive correlation to law enforcement academy graduation.

Abstract
Tactical personnel work in an occupation that involves tasks requiring a high level of cardiovascular fitness as well as muscular strength and endurance. The aim of this literature review was to identify and critique studies investigating the relationship between physical fitness, quantified by fitness assessment measures, and occupational task performance. Databases were searched for relevant articles which assessed a fitness measure and a measure of occupational performance. A total of 15 articles were included and were deemed to be of acceptable methodological quality (8.4/12 on the Critical Appraisal Skills Programme checklist). Included articles assessed a variety of fitness attributes and occupational tasks. Across tactical groups, there appear to be no standardized fitness tests that can determine occupational performance, with aerobic fitness, anaerobic fitness, strength, endurance, power, and agility all being associated with occupational task performance. A wide range of fitness assessments appears to be required to predict occupational performance within tactical personnel. Efforts should be made to base fitness assessments on occupational demands unique to both the environment and requirements of each individual tactical unit.

Abstract
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.

Abstract
Providing physical activity opportunities to children throughout the school day may be beneficial for children’s health and learning. Existing practices regarding the frequency, type and context of physical activity opportunities being provided to children in the early years of primary school remains largely unknown. The aim of this study was to observe Year 1 children’s physical activity and its contexts during school class time and identify opportunities to incorporate additional activity. A cross-sectional study was conducted with 34 Year 1 children (20 boys, 14 girls; mean age = 6.36 ± 0.34 years) from one primary school in Queensland, Australia. A modified version of the Observational System for Recording Physical Activity in Children—Elementary School was used to assess children’s physical activity and its contexts during class time. Observational data were collected over a four-week period. The frequencies (and percentages) of intervals of children’s activity observed in sedentary, light and moderate-to-vigorous intensities during different instructional and social contexts and physical settings were recorded and calculated. Pearson’s chi-square test of association was conducted to evaluate whether social context (group composition) was related to incidental physical activity. A total of 5305 observation intervals (i.e., 5 s observation interval followed by a 25 s recording interval) were available for analysis (~44 h of observation). Year 1 children were sedentary for the majority (86%) of observed intervals during school class time. Children spent limited time performing light (12% of intervals) and moderate-to-vigorous physical activity (2% of intervals). Organised physical activity observed during class time included physical education/school sport (5.9% of intervals) and classroom-based physical activity (2.8% of intervals). When children completed activities in small groups, they were significantly more likely to engage in incidental physical activity than when they completed activities as a whole class (χ2 = 94.73 p < 0.001). Incorporating movement into academic lessons or during transitions between lessons and classrooms may encourage children to be more active. Incidental physical activity may also be promoted through small group activities. Schools should ideally be encouraged and supported to employ a whole-of-school approach to physical activity promotion, which includes identifying and implementing opportunities for children to be active during class time.

Abstract
Background Tactical populations, such as military, firefighter and law enforcement populations, are known to suffer a relatively high number of musculoskeletal injuries, with the lower extremity of notable concern. The aim of this retrospective cohort study was to determine the profile of lower extremity musculoskeletal injuries within a state police agency. Methods Injury data were collected by an Australian state police force over a 7-year period (2009–2016) and records not meeting the definition for lower extremity musculoskeletal injury were excluded. Statistical analyses were descriptive, with frequencies, means and standard deviations calculated where applicable. Chi-square analysis was performed to compare injury profiles by gender. Ethics approval was granted by Bond University Human Research Ethics Committee (Research Protocol 15360). Results Of the initial 65,579 incident records, 12,452 (19%) related to lower extremity musculoskeletal injuries. The knee was the most commonly injured site (31.4%) with sprains/strains (42.3%) the most common nature of injury and arresting offenders (24.2%) the most common activity at time of injury. Slips/trips/falls (37.8%) was found to be the most common cause of injury. Variations were found between genders, most notably within the injury activity (p < .001). 27.1% of male officers were injured when arresting offenders compared to 16.5% for female officers. Walking/running contributed to 17.9% of female officer incidents compared to 9.3% for male officers. The mean number of hours worked prior to injury occurrence was 6.00 ± 3.56 h with significantly more injuries occurring in the middle third of the shift (4.34–8.67 h, p < 0.001). Conclusions While the proportion of injuries that affected the lower extremity was lower for police, the leading sites of injuries (knees and ankles) were similar to those of military and fire and rescue populations. Variations between genders suggest there may need to be differences in return-to-work rehabilitation.

Abstract
This article provides updated information comparing minimalist running shoes (MRS) to conventional running shoes (CRS). Our previous review found that, compared with running in CRS, transitioning to MRS resulted in lower energy cost and less ground contact occurring at the forefoot, resulting in lower impact forces. There was some increased risk of injury with MRS, although data were conflicting. A more recent 26-week study involved 30 trained runners using CRS and 31 using MRS. The proportion of training time in the assigned shoes increased by 5% each week. After the first 6 weeks of transition (35% of training time in the assigned shoe), energy cost was lower and 5-km running time faster in MRS compared with CRS. No further improvement occurred from weeks 6 to 26. There were no significant differences in injury incidence in the two groups (CRS = 37%, MRS = 52%; p = .24). Running-related pain was higher in the MRS group in the knee, shin, calf, and ankle and increased at these locations as running mileage increased. Risk of injury in MRS increased as participant body weight increased. These more recent data suggest that MRS can improve performance, but most runners should limit running in MRS to 35% of training time and in situations where optimal performance is desired (e.g., races, fitness tests).

Abstract
BACKGROUND AND PURPOSE The impact of stress and burnout in students is an emerging topic. When students perceive that they are unable to cope with stressors, there is increased potential for burnout. To maximise students' higher educational institution outcomes, students must be able to effectively cope with stressful demands. Research suggests physiotherapy students, in particular, suffer from a high risk of stress and burnout, however limited research exists on postgraduate, pre-registration, physiotherapy students. The purpose of this study was to determine perceived stress, burnout and associated coping strategies across three timepoints in the first year of a postgraduate, pre-registration physiotherapy program. METHODS A qualitative and quantitative survey design was utilised at one Australian Higher Education Institution. The 51-item self-administered questionnaire consisted of demographics, the Coping Self Efficacy (CSE) Scale and Maslach Burnout Inventory - General Survey for Students (MBI-GS (S)), and open-ended questions. The questionnaire was administered at three timepoints (T) in the program: T1 at the start of semester 1, T2 before the first placement in semester 2 and T3 after 10-weeks of placement. Data were analysed using descriptive, statistical and thematical analysis. SUBJECTS All first year Doctor of Physiotherapy students. RESULTS A response rate of 62% (n = 38) was achieved. There were no differences in stress and burnout scores between sexes, nor differences in stress and burnout over time. Highest median CSE scores were seen at T1, with highest median MBI-GS (S) cynicism scores at T2, exhaustion (EX) at T1 and T2, and professional efficacy at T1 and T2. The greatest mean CSE changes were seen from T1-T2 and T1-3, and PE greatest changes from T2-T3 and T1-T3. No strong correlation was found between stress and burnout. Curriculum coursework was a frequently reported stressor, along with clinical placement and transition periods. Coping strategies utilized by students were both positive and maladaptive. Positive strategies included sporting activities, baking, listening to music, and social connections, whereas maladaptive strategies included alcohol consumption, excessive eating, and gaming. CONCLUSION Student consistently identified periods of stress and burnout, with curriculum coursework in particular being a trigger. Findings acknowledge the need for further investigation on sources of perceived stress, burnout, and coping mechanisms to optimise student welfare and enhance Higher Education Institution outcomes.
