ObjectiveTo evaluate the effects of injury prevention programmes on injury incidence in any women’s football code; explore relationships between training components and injury risk; and report injury incidence for women’s football.DesignSystematic review and meta-analysis.Data sourcesNine databases searched in August 2019.Eligibility criteriaRandomised controlled trials evaluating any injury prevention programme (eg, exercise, education, braces) were included. Study inclusion criteria were: ≥20 female football players in each study arm (any age, football code or participation level) and injury incidence reporting.ResultsTwelve studies, all in soccer, met inclusion criteria, with nine involving adolescent teams (aged <18 years). All studies (except one) had a high risk of bias. Eleven studies examined exercise-based programmes, with most (9/11) including multiple (≥2) training components (eg, strength, plyometric, balance exercises). Multicomponent exercise programmes reduced overall (any reported) injuries (incidence rate ratio (IRR) 0.73, 95% CI 0.59 to 0.91) and ACL injuries (IRR 0.55, 95% CI 0.32 to 0.92). For exercise-based strategies (single-component and multicomponent), hamstring injuries were also reduced (IRR 0.40, 95% CI 0.17 to 0.95). While exercise-based strategies resulted in less knee, ankle and hip/groin injuries, and the use of multiple training components was associated with greater reductions in overall and knee injuries, further studies would be required to increase the precision of these results. The incidence of overall injuries in women’s football was 3.4 per 1000 exposure hours; with ankle injuries most common.ConclusionIn women’s football, there is low-level evidence that multicomponent, exercise-based programmes reduce overall and ACL injuries by 27% and 45%, respectively.PROSPERO registration numberCRD42018093527.

Background/AimGroin injury epidemiology has not previously been examined in an entire professional football league. We recorded and characterised time loss groin injuries sustained in the Qatar Stars League.MethodsMale players were observed prospectively from July 2013 to June 2015. Time loss injuries, individual training and match play exposure were recorded by club doctors using standardised surveillance methods. Groin injury incidence per 1000 playing hours was calculated, and descriptive statistics used to determine the prevalence and characteristics of groin injuries. The Doha agreement classification system was used to categorise all groin injuries.Results606 footballers from 17 clubs were included, with 206/1145 (18%) time loss groin injuries sustained by 150 players, at an incidence of 1.0/1000 hours (95% CI 0.9 to 1.1). At a club level, 21% (IQR 10%–28%) of players experienced groin injuries each season and 6.6 (IQR 2.9–9.1) injuries were sustained per club per season. Of the 206 injuries, 16% were minimal (1–3 days), 25% mild (4–7 days), 41% moderate (8–28 days) and 18% severe (>28 days), with a median absence of 10 days/injury (IQR 5–22 days). The median days lost due to groin injury per club was 85 days per season (IQR 35–215 days). Adductor-related groin pain was the most common entity (68%) followed by iliopsoas (12%) and pubic-related (9%) groin pain.ConclusionGroin pain caused time loss for one in five players each season. Adductor-related groin pain comprised 2/3 of all groin injuries. Improving treatment outcomes and preventing adductor-related groin pain has the potential to improve player availability in professional football.

Data to enhance inclusive healthcare Boudreaux et al (see page 351) pay tribute to the legacy of Dr Steven Noel Blair (4 July 1939–6 October 2023) for his pioneering role in using data to promote physical activity and public health, paving the way for future researchers. Education on data curation and management to provide sport staff with the skills, knowledge and awareness to appropriately share data will enhance research communication, collaboration and the quality of sports healthcare data. Highlighting these benefits, longitudinal health surveillance in UK Paralympic summer sport athletes from 2016 to 2019 presented by Rason and colleagues (see page 320) will inform development, implementation and evaluation of associated injury risk mitigation and management initiatives in para-athletes.

ObjectiveTo report the effectiveness of physiotherapist-led interventions in improving pain and function in young and middle-aged adults with hip-related pain.DesignSystematic review and meta-analysis.Data sourcesA comprehensive, reproducible search strategy was performed on five databases in May 2019. Reference lists and grey literature were also searched.Eligibility criteria for selecting studiesPopulation: people aged ≥18 years with hip-related pain (with or without a diagnosis of femoroacetabular impingement syndrome). Intervention(s): physiotherapist-led interventions for hip pain. Comparators: sham treatment, no treatment or other treatment (eg, hip arthroscopic surgery). Outcomes: primary outcomes included patient-reported hip pain and function. Secondary outcomes included physical function measures.Results1722 papers were identified. After exclusion criteria were applied, 14 studies were included for analysis. They had varied risk of bias. There were no full-scale placebo-controlled randomised controlled trials (RCTs) of physiotherapist-led treatment. Pooled effects ranged from moderate effects (0.67 (95% CI 0.07 to 1.26)) favouring physiotherapist-led intervention over no treatment post-arthroscopy, to weak effects (−0.32 (95% CI 0.57 to 0.07)) favouring hip arthroscopy over physiotherapist-led treatment.ConclusionPhysiotherapist-led interventions might improve pain and function in young and middle-aged adults with hip-related pain, however full-scale high-quality RCT studies are required.PROSPERO registration numberCRD42018089088.

ObjectivesWe evaluated the implementation of Prep-to-Play PRO, an injury prevention programme for women’s elite Australian Football League (AFLW).MethodsThe Reach, Effectiveness, Adoption, Implementation and Maintenance (RE-AIM) of Prep-to-Play PRO were assessed based on the proportion of AFLW players and/or staff who: were aware of the programme (R), believed it may reduce anterior cruciate ligament injury (E), attempted to implement any/all programme components (A), implemented all intended components as practically as possible (I) and intended future programme implementation (M). Quantitative and qualitative data were triangulated to assess 58 RE-AIM items (evidence of yes/no/unsure/no evidence) and the 5 RE-AIM dimensions (fully achieved=evidence of yes on >50% dimension items, partially achieved=50% of items evidence of yes and 50% unsure or 50% mix of unsure and unanswered, or not met=evidence of yes on <50% dimension items).ResultsMultiple sources including AFLW training observations (n=7 total), post-implementation surveys (141 players, 25 staff), semistructured interviews (19 players, 13 staff) and internal programme records (9 staff) contributed to the RE-AIM assessment. After the 2019 season, 8 of 10 (80%) AFLW clubs fully met all five RE-AIM dimensions. All 10 clubs participating in the AFLW fully achieved the reach (R) dimension. One club partially achieved the implementation (I) dimension, and one club partially achieved the effectiveness (E) and adoption (A) dimensions.ConclusionThe Prep-to-Play PRO injury prevention programme for the AFLW achieved high implementation, possibly due to the programme’s deliberately flexible approach coupled with our pragmatic definition of implementation. Engaging key stakeholders at multiple ecological levels (organisation, coaches, athletes) throughout programme development and implementation likely enhanced programme implementation.

ObjectiveThere are inconsistent reports of factors relating to injury, illness and tactical performance in law enforcement recruits. Our objectives were to: (1) report physical and psychological risk factors and protective factors for injury and illness and (2) report physical and psychological risk factors and protective factors for tactical performance success.DesignSystematic epidemiological review.MethodsSearches of six databases were conducted on 13 December 2022. We included cohorts that assessed physical and psychological factors for injury, illness and tactical performance success. Study quality was assessed using the Joanna Briggs Institute Quality Assessment Checklist for Prevalence Studies and certainty assessed using the Grading of Recommendations Assessment, Development and Evaluation.Results30 studies were included, and quality assessment was performed. Very low certainty of evidence exists for physical variables related to injury risk, and we found no studies that investigated psychological variables as a risk factor for injury. Low-certainty evidence found older age, poorer performance with push-up reps to failure, poorer arm ergometer revolutions, poorer beep test, poorer 75-yard pursuit and the 1.5 miles run tests to be associated with reduced tactical performance. Very low certainty of evidence exists that the psychological variables of intelligence and anger are associated with tactical performance.ConclusionsWe identified a lack of high-level evidence for factors associated with injury, illness and performance. Interventions based on this research will be suboptimal. We suggest context-specific factors related to injury, illness and performance in law enforcement populations are used to inform current practice while further, high-quality research into risk factors is performed.PROSPERO registration numberCRD42022381973.

BackgroundIntra-articular hip pathologies are thought to be associated with the development of hip and groin pain. A better understanding of the relationship between symptoms and imaging findings may improve the management of individuals with intra-articular hip pathologies.ObjectiveTo undertake a systematic review and meta-analysis to determine the prevalence of intra-articular hip pathologies in individuals with and without pain.MethodsSeven electronic databases were searched in February 2017 for studies investigating the prevalence of intra-articular hip pathologies using MRI, MRA or CT. Two independent reviewers conducted the search, study selection, quality appraisal and data extraction. Meta-analysis was performed when studies were deemed homogenous, with a strength of evidence assigned to pooled results.ResultsIn general, studies were moderate to high risk of bias, with only five studies adjudged to be low risk of bias. The 29 studies reporting on the prevalence of intra-articular hip pathologies identified limited evidence of a labral tear prevalence of 62% (95% CI 47% to 75%) in symptomatic individuals, with moderate evidence identifying a labral tear prevalence of 54% (95% CI 41% to 66%) in asymptomatic individuals. Limited evidence demonstrated a cartilage defect prevalence of 64% (95% CI 25% to 91%) in symptomatic individuals, compared with moderate evidence of a cartilage defect prevalence of 12% (95% CI 7% to 21%) in asymptomatic individuals.ConclusionThe prevalence of intra-articular hip pathologies is highly variable in both symptomatic and asymptomatic populations. The prevalence of intra-articular hip pathologies appears to be higher in symptomatic individuals. However, imaging-defined intra-articular hip pathologies are also frequently seen in asymptomatic individuals, highlighting a potential discordant relationship between imaging pathology and pain.PROSPERO registration number CRD42016035444.

To explore how injury, as a primary barrier, impacts physically inactive Australian women's engagement in sport and physical activity. Concept mapping. Participants used online concept mapping to brainstorm the meaning of injury, then sorted and rated statements for impact and importance (1 (low)–5 (high) scale). Multi-dimensional scaling, hierarchical cluster analysis and descriptive statistics were applied. Forty-five Australian women, aged 25–64, brainstormed 94 statements representing the meaning of an injury. Nine clusters emerged from analysis of the sorting data (highest to lowest mean cluster impact order): Fear and frustration; Physical implications of injury; Activity restrictions; Financial implications; Modification and management; Recovery; Mental and emotional wellbeing; Impact on daily life; and Social impact and engagement. A high correlation was found between rating scales (r = 0.92). A holistic approach is fundamental to understanding how the multi-dimensional impacts of injury and recovery affect physically inactive women. This approach should extend beyond the medical/physical aspects to other challenges and contextual factors (i.e. environmental and personal) impacting women's functioning. Understanding the diverse needs and experiences of physically inactive women is crucial for tailoring interventions that can effectively support recovery and sustained engagement, through person-centred strategies focused on injury prevention/management. Furthermore, this understanding is essential to fostering collaborative system-wide understanding and change, involving diverse stakeholders (e.g. health practitioners, those in delivery/practice settings, insurance) to improve long-term health and wellness outcomes, and promote greater participation in sport/physical activity.

ObjectivesInjury/poor health is an important barrier to women’s participation in sport and physical activity. This study aimed to identify perceived challenges sport programme deliverers face when supporting physically inactive women to prevent/manage injury.MethodsSport programme deliverers, targeting physically inactive women in Victoria, participated in concept mapping to brainstorm, sort and rate (impact on their ability to prevent/manage injury, frequency of and difficulty to overcome the challenge on a 1 (low)–5 (high) scale) the challenges faced. Analysis included multidimensional scaling, hierarchical cluster analysis and descriptive statistics (eg, mean ratings).ResultsTwenty-five deliverers brainstormed 82 injury prevention/management-related challenges. An eight cluster map was considered the most appropriate representation of the participants’ sorting data (mean cluster impact, frequency and difficulty to overcome rating (1–5)): time constraints (3.42, 3.69, 3.12); perceived competence in injury prevention/management (3.36, 3.50, 3.27); navigating participant perceptions and knowledge (3.35, 3.74, 3.49); information and responsibility (3.32, 3.50, 3.26); session planning and structure (3.25, 3.45, 3.07); participant engagement (3.13, 3.47, 3.08); responding to individual needs (3.07, 3.42, 2.92) and access to injury management resources (2.87, 3.25, 3.17).ConclusionLimited time created injury prevention/management challenges for programme deliverers when planning and modifying sport programmes for physically inactive women. Injury prevention/management should be integrated into programme design and delivery principles. Programme deliverers need education/training and access to injury prevention/management resources (eg, activity modification) and engagement/communication strategies tailored for physically inactive women. Public health funders, coaching course accreditors, programme designers and deliverers can use these insights to develop strategies to minimise injury risk and effect systemic change in sport programme delivery.

To determine the normal profiles for hip strength and range of motion (ROM) in a professional football league in Qatar, and examine the effect of leg dominance, age, past history of injury, and ethnicity on these profiles. Cross-sectional cohort study. Participants included 394 asymptomatic, male professional football players, aged 18–40 years. Strength was measured using a hand held dynamometer with an eccentric test in side-lying for hip adduction and abduction, and the squeeze test in supine with 45° hip flexion. Range of motion measures included: hip internal and external rotation in 90° flexion, hip IR in prone, bent knee fall out and hip abduction in side-lying. Demographic information was collected and the effect on the profiles was analysed using linear mixed models with repeated measures. Strength values (mean±SD) were: adduction=3.0±0.6Nm/kg, abduction=2.6±0.4Nm/kg, adduction/abduction ratio=1.2±0.2, Squeeze test=3.6±0.8N/kg. Range of motion values: internal rotation in flexion=32±8°, external rotation=38±8°, internal rotation in prone=38±8°, bent knee fall out=13±4.4cm, abduction in side-lying=50±7.3°. Leg dominance had no clinically relevant effect on these profiles. Multivariate analysis demonstrated that age had a minor influence on squeeze strength (−0.03N/kg/year), external rotation (−0.30°/year) and abduction range (−0.19°/year) but past history of injury, and ethnicity did not. Normal values are documented for hip strength and range of motion that can be used as reference profiles in the clinical assessment, screening, and management of professional football players. Leg dominance, recent past injury history and ethnicity do not need to be accounted for when using these profiles for comparison purposes.
