Design Systematic review. Data sources MEDLINE, SPORTDiscus, Web of Science and Cochrane Library from 2001 to June 2024. Eligibility criteria Original, peer-reviewed studies focusing on sport-related concussion, where video review identified visible signs or the mechanism of injury relevant to clinical decision-making. Studies were included irrespective of study design but had to be published in English and use a clinical diagnosis or consensus definition of sport-related concussion as a reference standard. Results Out of 1001 records screened, 29 studies involving 3281 sport-related concussions were included for quantitative synthesis. Only eight studies had a low risk of bias. All studies used clinical diagnosis as a reference standard; 26 were conducted in professional competitions, with two studies including female athletes. The most frequently observed visible sign was ‘slow to get up’ (37.6%), followed by ‘motor incoordination’ (26.7%). Sensitivity of visible signs was generally low (<50%), while specificity was high (>90%) across most studies. Four studies across three sports examined mechanism of injury characteristics, identifying common themes, such as high speed of impact, potentially associated with sport-related concussion occurrence. Inter-rater and intrarater reliability varied, with indications of higher reliability among expert raters. Conclusions Expert video review can reliably identify visible signs of sport-related concussion. However, due to their low frequency and limited diagnostic sensitivity, the diagnosis of sport-related concussion should be supported by a multimodal assessment. All data relevant to the study are included in the article or uploaded as supplementary information.","PeriodicalId":9276,"journal":{"name":"British Journal of Sports Medicine","volume":"70 1","pages":""},"PeriodicalIF":18.4,"publicationDate":"2025-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144311845","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}

The aim of this International Cartilage Regeneration & Joint Preservation Society, Fédération Internationale de Football Association, and Aspetar (ICRS-FIFA-Aspetar) consensus was to develop specific expert-based, patient-specific practical recommendations on the appropriateness of non-surgical or surgical treatments for symptomatic knee cartilage lesions in competitive football players. The RAND/UCLA appropriateness method was used, and 17 voting experts provided recommendations on the appropriateness of surgical treatment in 96 different clinical scenarios defined on 6 variables: cartilage injury onset, lesion location, defect size, bone involvement, player symptom level and preference towards higher priority of a quick return to play or long-term results. Surgical treatment of a cartilage lesion was considered appropriate in 32% of the scenarios, in 21% inappropriate, while in 47% of the scenarios, the appropriateness was considered uncertain. The parameters with the highest appropriateness for the surgical treatment of a cartilage lesion in a football player were the inability to play (75.0% of appropriate scenarios), a lesion sized 2 cm² or bigger (47.9% of appropriate scenarios) and the preference of the player for long-term results (41.7% of appropriate scenarios). In this ICRS-FIFA-Aspetar expert consensus, surgical treatment for cartilage injuries in competitive football players was considered appropriate only in one-third of the clinical scenarios, and the choice was mainly driven by the level of symptoms. Surgical preference was also influenced by larger lesions, lesions of the condyles and trochlea with subchondral bone involvement and player's preference towards long-term results.</p>","PeriodicalId":9276,"journal":{"name":"British Journal of Sports Medicine","volume":" ","pages":"902-911"},"PeriodicalIF":11.6,"publicationDate":"2025-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143405820","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}

The likelihood of developing PoP increases with age, multiparity, obesity, chronic cough and certain occupational or lifestyle factors.1 Women with PoP often report a fear of engaging in physical activity (PA), driven by concerns that it may exacerbate symptoms or accelerate prolapse progression.2 Surveys indicate that nearly one in three women with PoP cite their symptoms as a barrier to exercise, leading to reduced participation in both structured and recreational PA.2 3 Despite these concerns, the impact of PA on PoP remains unclear due to inconsistencies in research findings. Some studies suggest that high-impact activities may worsen symptoms, while others report no association or potential benefits of moderate exercise.4 5 The lack of definitive guidance leads many women to limit their PA unnecessarily, increasing the risk of sedentary behaviour and associated comorbidities such as cardiovascular disease and osteoporosis.4 5 Furthermore, surgical interventions such as mesh implants have introduced additional complications, with many women experiencing chronic pain that further reduces PA participation.6 The aim of this discussion is to highlight the key gaps that remain from previous research that limit understanding of the relationship between PA and PoP, and to recommend future research directions that are required to enable women to make informed decisions on …","PeriodicalId":9276,"journal":{"name":"British Journal of Sports Medicine","volume":"609 1","pages":""},"PeriodicalIF":18.4,"publicationDate":"2025-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144278440","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}

The potentially contradictory health effects of LTPA and OPA are referred to as the physical activity health paradox.1 OPA and LTPA occur in different contexts and settings that may differentially contribute to cardiometabolic health risk. LTPA typically consists of a wider range of body movements performed at levels that are sufficiently intense to improve cardiorespiratory fitness and metabolism, is performed voluntarily, and often occurs over shorter durations with adequate recovery time in between episodes. On the other hand, OPA typically includes static loading, lifting heavy objects, repetitive or painful body movements and postures, long durations (>8 hours) with low control, and inadequate periods of recovery in between episodes, which may attenuate health benefits or possibly increase health risks. For many minority and low-income populations, occupations such as cleaning, retail, cooking and elder/childcare constitute a common setting for OPA in the USA and other developed nations. Although individuals from socioeconomically disadvantaged backgrounds are physically active for large portions of each day performing these types of occupations, they remain in relatively poor health compared with their higher-income counterparts.2 OPA may represent a cause of health disparities that is not well understood.

Methods 68 fit and recreationally active children aged 10–16 years (31 girls), and 24 adults aged 18–40 years (11 females) completed three separate 45 min treadmill walking/running trials at different intensities on different days at 30°C, 40% relative humidity (RH) (WARM) or 40°C, 30% RH (HOT). Exposures were randomised to elicit intensities scaled to (1) fitness, (2) mass and (3) surface area. Core (gastrointestinal (Tgi)) temperature was measured continuously and dehydration determined using body mass changes. Results Except for 60% V̇O2peak in WARM, in which adults exhibited a greater Tgi rise compared with 10–13 years, there was no effect of age on Tgi during exercise (p≥0.176). Physiological rates of dehydration were not affected by age in WARM (p≥0.08) or HOT (p≥0.08). Mean predicted sweat rate error was +0.08 kg/hour (95% CIs: −0.10, +0.25) across WARM and HOT, and 80.5% of variability in sweating was explained by the adult sweat rate calculator. Conclusions Using the most comprehensive paediatric exercise heat stress dataset from a single study to date, we show that children aged 10–16 years are at a similar risk of hyperthermia and dehydration as adults during exercise up to 40°C. This supports recent changes to paediatric sport heat policies that were based on limited data. Practitioners can potentially reduce behavioural dehydration risks from inadequate fluid consumption using an existing adult sweat rate calculator for children.

This editorial introduces the concept of ‘powerpenia’ and presents insights for its potential clinical application in the future. The term ‘powerpenia’ has been introduced to describe a decline in ‘skeletal muscle’ power associated with ageing, disease and/or physical inactivity, and is proposed as a new biomarker of healthy ageing.4 Unlike the original concepts of sarcopenia and dynapenia, powerpenia centres on the power output observed during motor tasks derived from ‘skeletal muscle’ contractions.4 Compared with maximal strength and muscle mass, power is known to decline with age more rapidly, and to have higher association with an increased risk of falling, functional competence and quality of life in older adults.4 The introduction of the powerpenia concept is further supported by the recent exclusion of power testing (but not maximal strength testing) in the global conceptual definition of sarcopenia proposed by the Global Leadership Initiative in Sarcopenia .5 Moreover, multiple factors can influence the ageing rate (eg, sleep), which means that two human individuals of the same chronological age may be ageing at different rates. Our perspective is that human motor power is a better marker of biological age compared with muscle mass and strength; …","PeriodicalId":9276,"journal":{"name":"British Journal of Sports Medicine","volume":"8 1","pages":""},"PeriodicalIF":18.4,"publicationDate":"2025-06-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144260487","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}

Secondary objectives were to identify barriers and enablers encountered by elite athletes during preconception and pregnancy, and to use the study findings to develop recommendations to inform future pregnancy policies within sporting organisations. Methods 58 participants comprising 27 elite athletes, 20 support staff (eg, coaches, physicians, physiotherapists) and 11 sport organisational staff (eg, general managers, athlete well-being officers) from 25 sports participated in either a focus group (n=45) or semi-structured interview (n=13) conducted between 14 August 2023 and 21 November 2023. Focus groups and interviews were audio-recorded, transcribed verbatim and analysed using thematic analysis. Results The vast majority of athletes felt that organisational support for preconception and pregnancy was inadequate. Their feedback was categorised into four distinct themes: (1) planning, fertility and disclosure; (2) mindset; (3) training during preconception and pregnancy and (4) access to support and information. Within these themes, participants highlighted barriers (eg, lack of knowledge, impaired fertility, pregnancy symptoms) and opportunities for organisations to improve the current level of support provided (eg, education, fertility treatments, training flexibility). Overall, 22 recommendations were developed to guide Australian sporting organisations in future pregnancy policies. Conclusion Australian elite female athletes continue to face numerous barriers during preconception and pregnancy. Sporting organisations can use the findings and recommendations within this study to develop pregnancy policies, which better support female athletes. Data are available on reasonable request.
