However, empirical details on the development and implementation of a comprehensive mental health support programme at international sporting events are lacking. Therefore, this paper aims to provide consensus-driven, evidence-based recommendations to guide such a development and implementation. An 8-stage process based on the RAND-UCLA Appropriateness Method was adopted to collate and synthesise the available literature on this topic, to identify gaps in the scientific evidence and to enlist expert experience from a multidisciplinary expert panel to fill these gaps. Within such a process, the existing scientific literature was explored while experts (including athletes) were consulted to reach consensus on the recommendations. Accordingly, a robust pre-event plan is required to ensure the successful implementation of a comprehensive mental health programme during sport events, focussing on promotion, prevention, treatment and recovery. During sporting events, according to the defined pre-event plan, various activities targeting athletes, coaches, the entourage, officials or fans should be implemented: for example, educational programmes to decrease stigma, raise awareness and support help-seeking, a mental fitness area for decompression and relaxation, inperson mental health services provided by qualified mental health professionals with sport-specific as well as trauma-informed and violence-informed skills and mental health surveillance in parallel with the existing injury and illness surveillance programmes. Post event, a thorough evaluation of the implemented activities should be conducted while surveillance data should be analysed to identify areas requiring future targeted intervention(s). Also, particular attention should be given to postevent mental health support including the use of decompression interventions to support adjustment, emotional processing and reintegration.","PeriodicalId":9276,"journal":{"name":"British Journal of Sports Medicine","volume":"37 1","pages":""},"PeriodicalIF":18.4,"publicationDate":"2025-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144693347","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}

ACL injury is a complex phenomenon wherein various risk factors interact dynamically, thereby influencing the likelihood of injury in athletes.1 2 In light of this, it is essential to investigate the interrelationships among the risk factors to develop effective injury prevention strategies. Furthermore, screening tests that can be easily administered in field settings multiple times throughout the season, without compromising the validity and reliability of the data obtained, are necessary to identify possible negative adaptations in athletes. My doctoral research was structured into two primary phases. The initial phase involved a qualitative study that aimed to develop a Causal Loop Diagram (CLD) model and elucidate the aetiology of ACL injuries.

Significant change in sport relies on effective reporting processes, where people at all levels of sport can call out behaviour that breaches boundaries and puts people at risk. Yet, an expectation or particularly the obligation to speak up4 creates a persistent tension: people do not always feel safe enough to do so. Speaking up can include raising concerns about issues such as safety, well-being or conduct, often occurring informally, while whistleblowing is the process of formally reporting serious wrongdoing, unethical behaviour, severe harm or unsafe behaviours, typically through official channels, often when other routes have failed.5 Too often, “speaking up” is framed exclusively as something athletes must do, but welfare is not an athlete-only issue, and all support staff have a responsibility in this sphere.6 Across sport, support staff, including physiotherapists, psychologists and performance scientists, often described as the athlete entourage,3 frequently find themselves in ethically complex situations, where challenging decisions or questioning authority can feel personally and professionally …","PeriodicalId":9276,"journal":{"name":"British Journal of Sports Medicine","volume":"19 1","pages":""},"PeriodicalIF":18.4,"publicationDate":"2025-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144611009","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}

Results Across 82 studies—including 48 randomised controlled trials (59%), 16 quasiexperimental studies (20%), 16 cohort studies (20%) and 1 cross-sectional study (1%)—a total of 154 561 participants were included, of whom 84 915 (55%) were females/women/girls.

The median Downs and Black score for all studies was 17 (range: 5–24). Point estimate from pooled results from nine studies revealed that NMT programmes, which include LE balance, strength, agility and change of direction exercises, with a minimum dose of 10 min two times per week, reduced female/woman/girl athletes’ LE injuries by 19% (0.81, 95% CI 0.61% to 1.08%; low certainty evidence).

Methods Adult runners were recruited for an 18-month cohort study. Three training-related exposures were defined based on a relative change in running distance, using data collected via Garmin devices: (1) session-specific running distance relative to the longest distance run in the past 30 days; (2) 1-week period relative to the preceding 3 weeks using the acute:chronic workload ratio (ACWR); (3) 1-week period using a week-to-week ratio. Runners were categorised into one of four time-varying states: (1) regression, or up to 10% increase (reference); (2) ‘small spike’ between >10% and 30% increase; (3) ‘moderate spike’ between >30% and 100% increase; and (4) ‘large spike’ >100% increase. Outcome was self-reported overuse running-related injury. A multistate Cox regression model was used to estimate adjusted hazard rate ratios (HRR). Results Among 5205 runners (mean age 45.8 years, SD=10.4; 22% female), a total of 1820 (35%) sustained a running-related injury during 588 071 sessions.
