However, as the volume of evidence has increased, so has the number of independent investigators leading to the collection and storage of small, granular datasets by individual labs during routine research.1 There are growing concerns within sports medicine and related fields that the complex nature of the current scientific environment may limit the efficiency of data aggregation and that variation in the structure of individual datasets may limit the application of rigorous quantitative methods when answering challenging clinical or practical questions.2 3 Therefore, this editorial aims to introduce the concepts of long tail data and dark data in sports medicine research and describe the implications of both data types for advancing the field. The concepts of long tail data and dark data are becoming increasingly relevant in sports medicine and orthopaedics research. Long tail data refers to the vast amount of small, specialised datasets that exist outside of mainstream, large-scale studies.2 4 These datasets, often collected by individual researchers or small labs, contain valuable information but may be overlooked due to their small size, perceived lack of significance, or correlation with other datasets. For example, in patient-outcomes research, data becomes fragmented between studies or sites depending on when follow-up and final visits take place during the course of care, and also from the structure and frequency of physical assessment sessions typically implemented in preparation for clearance to return to activity. Furthermore, when data is collected as part of patient care, changing measures to align with collaborating institutions or recent research can be onerous and disrupt the workflows of clinicians. Dark data, a subset of long tail data, encompasses the information collected during research …","PeriodicalId":9276,"journal":{"name":"British Journal of Sports Medicine","volume":"74 1","pages":""},"PeriodicalIF":18.4,"publicationDate":"2025-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143841289","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}

{"title":"Role of sit-to-stand muscle power in healthy ageing: assessing validity, clinical relevance, decline and interventions in older adults with and without chronic conditions (PhD Academy Award)","authors":"Ivan Baltasar-Fernandez","doi":"10.1136/bjsports-2024-109594","DOIUrl":"https://doi.org/10.1136/bjsports-2024-109594","url":null,"abstract":"This PhD thesis aimed: (i) to assess the validity of the sit-to-stand (STS) muscle power test and compare it with other equations available in the literature; (ii) to investigate the functional implications of having low relative STS power (ie, normalised by body mass) in older individuals with and without Parkinson’s disease (PD); (iii) to assess longitudinal changes in relative STS power and its contributing factors, providing clinically relevant cut-off points for low relative STS power; and (iv) to evaluate the short-term and residual effects of power-oriented resistance training (RT) combined with high-intensity interval training (HIIT) in frail older adults and in those with chronic obstructive pulmonary disease (COPD). Muscle power, a critical component of the neuromuscular system, declines more rapidly than muscle mass and strength with ageing and is a stronger predictor of adverse health outcomes, including frailty, disability, and falls. However, the lack of feasible and valid tests, normative values and cut-off points has so far prevented its evaluation in the clinical setting. Given the WHO’s emphasis on healthy ageing and maintaining functional ability, it is essential to identify and implement effective strategies to assess and enhance muscle power, thereby supporting independence and well-being in older populations. Thus, the validity and clinical relevance of the STS muscle power test deserved to be investigated. My PhD thesis comprised eight studies, including cross-sectional (studies 1–4), an 8-year longitudinal (study 5) and interventional (studies 6–8) designs. Participants included 2183 community-dwelling older adults (>65 years), 46 age- and sex-matched individuals with and without PD (>60 years), 59 older adults with frailty (>70 years) and 21 older adults with COPD (>65 years).

Determining the optimal cardiac screening, the use of carefully selected medical assessments to detect underlying cardiovascular conditions associated with sudden cardiac arrest/death, is a desired objective of the Fédération Internationale de Football Association (FIFA) for football players of all ages. To date, cardiac screening recommendations in football have primarily focused on adult competitive players. Acknowledging its responsibility for player health worldwide, FIFA convened an international working group of cardiology and sports medicine experts to develop cardiac screening recommendations for youth football players. This group performed structured literature reviews and ultimately congregated in January of 2024, when recommendations were presented, scrutinised and judged using a systematic process. The final FIFA recommendations for youth cardiac screening include personal medical history, family medical history, focused physical examination and resting 12-lead electrocardiography.

It is dedicated to supporting individuals suffering from mental health disorders through regular physical activity. The organisation aims to improve the mental well-being of its participants by combining exercise and social connection. Mental health is a major issue in France, affecting 13 million people each year. In 2021, 13.3% of adults aged 18–85 experienced depressive disorders, representing a 3.5% increase from 2017.1 These disorders disproportionately impact vulnerable populations (women, unemployed individuals, single parents), exacerbating social inequalities. According to the French Ministry of Health and Prevention, mental healthcare is the largest expenditure for France’s national health insurance system, costing €23 billion per year—more than cancer and cardiovascular diseases.2 A large body of studies has demonstrated the effectiveness of physical activity in relation to a number of mental health conditions.3 It helps prevent the onset of mental health issues, accelerates recovery and reduces the risk of relapse. However, existing sports and fitness structures are often ill suited to individuals facing psychological disorders.

Design Scoping review. Data sources Online databases (MEDLINE, EMBASE, CINAHL, SPORTDiscuss, Evidence-Based Medicine Reviews (Ovid), Scopus, Web of Science and ClinicalTrials.gov) and Google up to 14 June 2024. Additionally, a targeted search of existing policies was conducted via the websites of International Federations (IFs) and continental sporting organisations (CSOs) in September 2023. Eligibility criteria We included policies from IFs recognised by the International Olympic Committee, and CSOs associated with the IFs that specifically address pregnant, postpartum or parenting athletes. Policies were a written principle of action adopted by the IFs/CSOs that provided any form of support during pregnancy, post partum or for parents. Results A total of 219 organisations (49 IFs; 170 CSOs) were identified and contacted, with 47/49 (96%) IFs and 15/170 (9%) CSOs responding. Sport policies related to pregnancy, postpartum or parenting athletes were identified from 20 IFs including (1) guidance on training/competition during and following pregnancy; (2) eligibility affected or training not advised; (3) protection from dismissal; (4) special rank, points or quota protection; (5) protections apply to adoption, surrogacy, miscarriage, stillbirth, egg freezing and/or fertility treatment; (6) duration of leave and if leave is paid and (7) breastfeeding support/space. No policies identified specific provisions for childcare support/space. Conclusions Less than half of all IFs have developed sport policies to support pregnant, postpartum and parenting athletes. Of the policies that do exist, most are limited in the extent to which they address the broad range of biopsychosocial supports that are necessary for facilitating optimal performance, enhancing long-term athlete health and addressing gender inequities that are deeply entrenched across all levels of sport. This review provides a critical piece of evidence needed to inform future policy development.
