The impact of interpersonal violence, often referred to as ‘harassment and abuse’ in sport policy documents, extends far beyond the individual, touching families, healthcare systems and society.1 In recent years, safeguarding strategies have emerged as a vital strategy to protect athletes in the Olympic Movement, with the International Olympic Committee (IOC) as a key actor. However, the landscape of safeguarding policies and practices within Summer and Winter Olympic International Federations (IFs) still reveals considerable variation, often lacking consistency and comprehensive implementation. Recognising these gaps, an internal quality control project driven by the IOC Safe Sport Unit set out to establish a framework for monitoring and evaluating the safeguarding efforts of IFs. By developing a set of indicators (see table 1), the project aimed to create a baseline framework for measuring safeguarding activities and to provide a tool for tracking changes over time. Through the application of this framework, it becomes possible to identify key challenges and areas in need of attention, resulting in the ability to support IFs in strengthening their safeguarding activities by pinpointing critical gaps. View this table: Table 1 Proposed set of safeguarding indicators for sport organisations All 39 Summer and Winter Olympic IFs participated, reflecting the importance placed on safeguarding by the sports community. As of 2022, 85% of these IFs reported having safeguarding policies, while only just over half had fully implemented them. Safeguarding officers, who are critical to the success of these policies, were predominantly women (54%), but a significant proportion (38%) did not officially hold the title of safeguarding officer or did not receive specialised training (49%), suggesting that many are working without the full recognition, support or training their role requires. …","PeriodicalId":9276,"journal":{"name":"British Journal of Sports Medicine","volume":"29 1","pages":""},"PeriodicalIF":18.4,"publicationDate":"2024-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142440199","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Design Systematic review and meta-analysis. Data sources Eight electronic databases (MEDLINE, EMBASE, EMCARE, AMED, PsycINFO, CINAHL, SPORTDiscus, and Web of Science) and two clinical trial registries (ClinicalTrials.gov and WHO International Clinical Trials Registry Platform) were searched from inception to 19 June 2024. Eligibility criteria Randomised controlled trials were eligible if they examined the effects of strength training compared with no exercise or usual care and reported at least one exercise prescription parameter. An advisory group of community members with lived experience of stroke helped inform outcomes most relevant to stroke recovery. Results Forty-two randomised trials (N=2204) were included. Overall risk of bias was high across most outcomes. Strength training improved outcomes rated as ‘critical for decision-making’ by the advisory group, including walking capacity (standardised mean difference (SMD)=0.95 (95% CI 0.34–1.56)), balance (SMD=1.13 (0.51–1.75)), functional ability and mobility (SMD=0.61 (0.09–1.14)), and habitual (mean difference (MD)=0.05 m/s (0.02–0.09)) and fast-paced walking speed (MD=0.09 m/s (0.01–0.17)), with very low to moderate certainty of evidence, mainly due to risk of bias and inconsistency. More frequent strength training, traditional strength training programmes and power-focused intensities (ie, emphasis on movement velocity) were positively associated with walking capacity, health-related quality of life and fast-paced walking speed. Conclusion Strength training alone or combined with usual care improves stroke recovery outcomes that are important for decision-making. More frequent strength training, power-focused intensities and traditional programme designs may best support stroke recovery. PROSPERO registration number CRD42023414077.

Agreement between subproject results informed the strength of clinical recommendation for interventions eligible for best practice recommendation.DATA SOURCESMedline, Web of Science, Scopus, reference lists and citation tracking; semistructured interviews of people with PFP; and semistructured interviews and focus groups with clinical experts.ELIGIBILITY CRITERIAHigh-quality (PEDro scale >7) randomised controlled trials (RCTs) were retained for efficacy estimation using meta-analysis. People with PFP were required to have experienced an episode of care in the past 6 months and clinical experts were required to have>5 years of clinical experience alongside direct involvement in research.RESULTSData from 65 high-quality RCTs involving 3796 participants informed 11 meta-analyses of interventions. Interviews with 12 people with PFP led to 3 themes and interviews with 19 clinical experts led to 4 themes. These were further explored in three clinical expert focus groups. Best practice for PFP should first involve understanding a patient's background risk factors, their reasons for seeking care, greatest symptoms, and physical impairments, to inform treatment selection. Synthesis led to six distinct interventions being recommended. Knee-targeted±hip-targeted exercise therapy underpinned by education should be delivered, with additional supporting interventions such as prefabricated foot orthoses, manual therapy, movement/running retraining, or taping decided on and tailored to a patient's needs and preferences.CONCLUSIONA best practice guide based on a synthesis of three data streams recommends that exercise therapy and education be delivered as the primary intervention for people with PFP. Prescription of other supporting interventions should be aligned with the individual patient's particular presentation following a thorough assessment.","PeriodicalId":9276,"journal":{"name":"British Journal of Sports Medicine","volume":"66 1","pages":""},"PeriodicalIF":18.4,"publicationDate":"2024-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142439247","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study assessed the efficacy and acceptability of running in adults with chronic LBP. Methods This two-arm parallel (1:1) individually randomised controlled trial allocated 40 participants (mean (SD) age: 33 (6) years, female: 50%) with non-specific chronic LBP to a 12-week intervention or waitlist control. The intervention was a progressive run–walk interval programme comprising three 30-min sessions per week that were digitally delivered and remotely supported by an exercise physiologist. Efficacy outcomes were self-reported pain intensity (100-point visual analogue scale) and disability (Oswestry Disability Index). Acceptability outcomes were attrition, adherence and adverse events. Results At 12-week follow-up, the intervention improved average pain intensity (mean net difference (95% CI): −15.30 (–25.33, –5.27) points, p=0.003), current pain intensity (−19.35 (–32.01, –6.69) points, p=0.003) and disability (−5.20 (–10.12, –0.24) points, P=0.038), compared with control. There was no attrition, and mean (SD) training adherence was 70% (20%; ie, 2.1 of 3 sessions per week). Nine non-serious adverse events deemed likely study-related were reported (lower limb injury/pain: n=7, syncope associated with an underlying condition: n=1, LBP: n=1). Conclusions A run–walk programme was considered an acceptable intervention by the participants to improve the pain intensity and disability in individuals aged 18–45 years with non-specific chronic LBP when compared with the control. An individualised and conservative run–walk programme should be considered a suitable form of physical activity for adults with chronic LBP.

Results For SEM practitioners currently working in elite sport, men worked more paid hours each week (mean difference (MD) 12.2 (95% CI 5.5 to 19.0)) and more paid weeks each year (MD 6.8 (95% CI 1.2 to 12.5)). Women SEM practitioners (both currently and previously) were more likely than men to work with women, rather than men athletes. All women SEM practitioners experienced significantly more gender harassment, infantilisation, work/family policing and gender policing than men. For SEM practitioners (both current and previous), there were no gender differences in how practitioners found out about or were recruited to their elite sports roles. Women were four times more likely than men to report that their gender or sexual orientation influenced their opportunities in elite sport. Most roles were not advertised with direct approach being the most common method of job recruitment.

Results 103 studies involving 36 439 participants (42 816 knees) were included. Based on very low certainty evidence, the pooled prevalence of knee crepitus in the general population was 41% (7609 knees; 95% CI 36% to 45%; I2=92.6%); in pain-free persons 36% (852 knees; 95% CI 23% to 50%; I2=91.9%), and in those with osteoarthritis (OA) 81% (18 821 knees; 95% CI 75% to 87%; I2=97.9%).
