To address the challenges posed by differences in biological maturity and the limitations of existing testing methods, particularly in adolescent sports contexts, there is a pressing need for a non-invasive method that is convenient, accurate, and broadly applicable to monitor the biological maturity of adolescent athletes comprehensively. In response to this need, a maturity assessment method based on the smartphone application Maturo has been developed. This study evaluates the accuracy and validity of the Maturo software, an automated tool for estimating biological age and related maturation metrics METHODS: A sample of 103 actively training teenage athletes aged 9 - 17 years. The sample included 76 males (11.74 ±1.55, mean ± SD) and 27 females (age = 13.95 ±1.40), all without medical conditions that might impact growth or development.RESULTSCompared to traditional expert evaluations, the intraclass correlation coefficients (ICCs) and Pearson correlation coefficients demonstrated reliable positive correlations and significant agreement between the Maturo software and expert methods across multiple metrics, such as biological age (ICC = 0.965, R = 0.97), corrected biological age (ICC = 0.973, R = 0.99), predicted adult height (ICC = 0.991, R = 0.99), and percentage of adult height achieved (ICC = 0.955, R = 0.97). The Bland-Altman plots provided additional evidence of the validity of the Maturo software estimations, showing low systematic error in most measures. The linear regression analysis produced excellent adjusted R-squared values: 0.95 for biological age and 0.99 for anticipated adult height. The Maturo approach demonstrated a high level of dependability in classifying teenagers into groups based on their maturity status and timing. The kappa coefficients of 0.93 for maturity status and 0.82 for maturity timing indicate a nearly perfect agreement with the expert technique.CONCLUSIONWhile the Maturo software's non-invasive nature, cost-effectiveness, and ease of use could make it a potential tool for regular monitoring of growth and maturation in young athletes, its promising results in assessing maturation should be interpreted with caution due to limitations such as sample size and demographic constraints. Further longitude research with larger and more diverse populations is needed to validate these preliminary findings and strengthen the evidence for its broader Applicability.","PeriodicalId":48897,"journal":{"name":"Journal of Sport and Health Science","volume":"70 1","pages":"101046"},"PeriodicalIF":11.7,"publicationDate":"2025-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143903117","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}

Thus, this systematic scoping review aimed to summarize the current ethical implications associated with using AI in sports.METHODSIn this study, a total of 9 databases-MEDLINE/PubMed, Embase, Cochrane Library, ProQuest, EBSCOhost, IEEE Xplore, Web of Science, Scopus, and Google Scholar-were searched. The review protocol was registered (https://osf.io/42a8q) before extracting data. The search yielded 397 studies, and 25 studies met the inclusion and exclusion criteria.RESULTSTHE 25 STUDIES WERE CATEGORIZED INTO 4 PRIMARY ETHICAL CONCERNS: fairness and bias, transparency and explainability, privacy and data ethics, and accountability in AI's application in sports. These categorizations were derived based on the systematic review of ethical issues highlighted across the selected studies. Fifteen studies delved into fairness and bias, focusing on how AI can perpetuate existing inequalities in sports. Thirteen studies addressed the lack of transparency, emphasizing the challenges in interpretability and trust in AI-driven decisions. Privacy and data ethics emerged as significant in 22 studies, highlighting risks related to the misuse of athletes' sensitive data. Finally, accountability was examined in 8 studies, stressing the ethical obligations of AI developers and users in sports contexts. The thematic analysis revealed overlapping concerns, as some studies addressed multiple issues simultaneously.CONCLUSIONFuture research should focus on developing ethical frameworks tailored to underrepresented sports contexts and creating global standards for AI regulation in sports. This includes investigating the implications of AI applications in amateur sports, enhancing diversity in AI training datasets, and exploring the integration of ethical AI practices across various sports governance structures.","PeriodicalId":48897,"journal":{"name":"Journal of Sport and Health Science","volume":"109 1","pages":"101047"},"PeriodicalIF":11.7,"publicationDate":"2025-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143903069","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}

Physical activity (PA) is crucial for healthy aging, yet many older adults struggle to exercise regularly. Artificial intelligence (AI)-powered social robots offer an interactive, engaging, and personalized solution to promote PA among this demographic. This systematic review investigates the role of AI-powered social robots in encouraging PA in older adults.METHODSWe conducted a systematic literature search in databases including PubMed, IEEE Xplore, Scopus, Cochrane Library, and Web of Science, focusing on studies published until February 2024. We included peer-reviewed articles reporting empirical findings on designing, implementing, and evaluating AI-enabled social robots to promote PA among older adults. Studies were conducted in nursing homes, rehabilitation centers, community centers, and home environments.RESULTSA total of 19 studies were included in the review. Analysis reveals that AI-powered social robots effectively motivate older adults to engage in PAs, leading to increased exercise adherence, higher engagement levels, and extended training durations. Social robots have demonstrated effectiveness across various environments, including nursing homes, rehabilitation centers, community centers, home environments, and elder care facilities. In structured environments like nursing homes and rehabilitation centers, robots help maintain regular exercise routines, improving adherence and recovery outcomes. In community and elder care centers, robots promote PA and social engagement by facilitating group exercises and enhancing participation. In home environments, robots provide personalized support for daily activities, offering reminders and engagement, which fosters long-term activity engagement. User acceptance and satisfaction are high, with participants finding the robots engaging and enjoyable. Additionally, several studies indicate potential health benefits, such as improved medication adherence, better sleep patterns, and enhanced overall well-being. Nevertheless, additional research is imperative to address unresolved issues concerning the technological maintenance costs, design constraints, and adaptability of AI-powered social robots to specific user demographics.CONCLUSIONAI-powered social robots play a promising role in promoting PA among older adults, enhancing their health, well-being, and independence. This review provides insights for researchers, designers, and healthcare professionals developing AI-enabled social robotic systems for older adults.","PeriodicalId":48897,"journal":{"name":"Journal of Sport and Health Science","volume":"16 1","pages":"101045"},"PeriodicalIF":11.7,"publicationDate":"2025-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143885481","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 systematic literature review investigates whether acute and short-term exercise interventions can mitigate negative effects of experimentally-induced sleep loss on metabolic markers in humans.METHODSA systematic search (PubMed, Web of Science, Scopus, Embase, SPORTDiscus, and Cochrane) following Preferred Reporting Items for Systematic Reviews and Meta-Analyses 2020 guidelines was conducted up to June 2024 for studies that compared glucose and insulin concentrations, insulin sensitivity, skeletal muscle gene expression, and other molecular markers following an acute or short-term (<14 days) exercise intervention during experimentally-induced sleep loss in adult humans. Articles were considered for inclusion and assessed for eligibility using the PICOS (Population, Intervention, Comparison, Outcomes, and Study design) framework, and critically appraised with the Cochrane Risk of Bias 2.0 tool.RESULTSOf the identified records, 4026 records were screened, with 12 studies meeting all the inclusion criteria and including 177 participants. Sleep intervention varied from a single night of total sleep deprivation to 5 consecutive nights of 4-h sleep opportunity (e.g., early or late sleep restriction), while exercise intervention varied in terms of model (walking/running, cycling, and resistance exercise), volume (e.g., minute to hour), and intensity (e.g., maximum efforts to low-intensity exercise). Most studies indicated a negative effect of insufficient sleep on glucose and insulin concentration as well as mitochondrial adaptations, whereas exercise had a positive impact, mitigating the negative effects on the aforementioned parameters.CONCLUSIONExercise is likely to be effective as a therapeutic intervention for mitigating the negative effects of sleep loss on metabolic markers, at least in short-term intervention studies.","PeriodicalId":48897,"journal":{"name":"Journal of Sport and Health Science","volume":"24 1","pages":"101044"},"PeriodicalIF":11.7,"publicationDate":"2025-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143884996","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}

We aimed to evaluate the prevalence of arrhythmias and their relationship with cardiac remodeling in lifelong and retired master endurance athletes compared to non-athletic controls.METHODSWe performed a cross-sectional analysis of observational studies that used echocardiography and cardiac magnetic resonance to detail cardiac structure and function, and Holter monitors to identify atrial and ventricular arrhythmias in 185 endurance athletes and 81 non-athletic controls aged ≥ 40 years. Athletes were categorised as active lifelong (n = 144) or retired (n = 41) based on hours per week of high-intensity endurance exercise within 5 years of enrollment and validated by percentage of predicted maximal oxygen consumption (VO2max). Athletes with overt cardiomyopathies, channelopathies, pre-excitation, and/or myocardial infarction were excluded.RESULTSLifelong athletes (median age = 55 years (interquartile range (IQR): 46-62), 79% male) were significantly fitter than retired athletes (median age = 66 years (IQR: 58-71), 95% male) and controls (median age = 53 years (IQR: 48-60), 96% male), respectively (predicted VO2max: 131% ± 18% vs. 99% ± 14% vs. 98% ± 15%, p < 0.001). Compared to controls, athletes in our cohort had a higher prevalence of atrial fibrillation ((AF): 32% vs. 0%, p < 0.001) and non-sustained ventricular tachycardia ((NSVT): 9% vs. 1%, p < 0.001). There was no difference in prevalence of any arrhythmia between lifelong and retired athletes. Lifelong athletes had larger ventricular volumes than retired athletes, who had ventricular volumes similar to controls (left ventricular end-diastolic volume indexed to body surface area (LVEDVi): 101 ± 20 mL/m2vs. 86 ± 16 mL/m2vs. 94 ± 18 mL/m2, p < 0.001; right ventricular end-diastolic volume indexed to body surface area (RVEDVi): 117 ± 23 mL/m2vs. 101 ± 19 mL/m2vs. 100 ± 19 mL/m2, p < 0.001).

Rapid release of extracellular vesicles (EVs) during exercise suggests their potential role as mediators of exercise-induced systemic effects and physiological adaptation. This study investigated the impact of exercise-induced plasma EVs on tumor growth and immune tumor microenvironment in murine models of triple-negative breast cancer (TNBC): EO771 (a C57BL/6-derived TNBC cell line) and 4T1 (a BALB/c-derived TNBC cell line).METHODSSize exclusion chromatography was used to isolate exercise-induced EVs from plasma of healthy female mice (BALB/c and C56BL/6, n = 30 per strain) that underwent ten 30-min moderate-intensity treadmill running sessions over 2 weeks. Nanoparticle tracking analysis, Western blot, and electron microscopy confirmed the presence of EVs in the samples. Tumor-bearing mice (n = 72 per strain) were administered with exercise-induced EVs before or/and after tumor implantation. Local and systemic immune responses were assessed using flow cytometry, enzyme-linked immunosorbent assay (ELISA), and quantitative polymerase chain reaction (qPCR).RESULTSAdministration of exercise-induced EVs, particularly before tumor implantation, significantly suppressed tumor growth and reduced tumor burden in both TNBC models. In EO771, endpoint tumor volumes were 278-330 mm³ in treated groups compared to 799 mm³ in untreated (p < 0.0001), while in 4T1, treated groups showed volumes of 287-564 mm³ vs. 696 mm³ in untreated (p = 0.0002). Notable differences in tumor-infiltrating lymphoid and myeloid cell subpopulations indicated immunomodulatory effects of exercise-induced EVs, particularly in the 4T1 model, where their continuous administration significantly increased intratumoral cluster of differentiation 8 (CD8) T lymphocyte proportion (5.77% vs. 0.90% in untreated, p < 0.0001). Similarly, in the EO771 model, exercise-induced EVs administered before tumor implantation led to a marked rise in intratumoral CD8 T lymphocytes (2.24% vs. 1.08% in untreated, p = 0.0181).CONCLUSIONOur findings indicate that exercise-induced EV treatment elicits a pro-inflammatory antitumor immune response, suggesting a shift of immunologically cold TNBC tumors towards a more inflamed phenotype associated with better outcomes. Our study supports the further investigation of EVs as modulators of antitumor immunity and their potential utility in enhancing the efficacy of immunotherapy.","PeriodicalId":48897,"journal":{"name":"Journal of Sport and Health Science","volume":"247 1","pages":"101041"},"PeriodicalIF":11.7,"publicationDate":"2025-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143851021","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}

While physical activity (PA) and physical fitness are both thought to reduce MSD risk, their independent and joint associations with MSD incidence have not been fully explored. This study investigated the independent and combined effects of PA, cardiorespiratory fitness (CRF), grip strength (GS), and GS asymmetry on MSD incidence in a large prospective cohort.METHODSWe analyzed data from the UK Biobank cohort (2006-2023), including 406,080 participants aged 37-73 years (age = 55.7 ± 8.2 years, mean ± SD; 53.0% female) who were free of MSD at baseline and during the first 2 years of follow-up. PA, derived from self-reported data and expressed in total metabolic equivalent hours per week (MET-h/week); CRF (watts (W)/kilogram (kg)), measured using a cycling exercise test; and GS (kg), measured by hydraulic hand dynamometer, were included as exposures. GS asymmetry was defined by the left-to-right hand strength ratio. MSD incidence was determined via hospital records. Time-to-event associations were analyzed using Cox proportional hazards regression models with restricted cubic splines to account for non-linear relationships. The analysis was conducted in April 2024.RESULTSOver a median follow-up of 14.7 years, a total of 73,002 incident cases of MSDs were recorded (rheumatoid arthritis: 2923; osteoarthritis: 54,955; degenerative spinal diseases: 15,124). Lower self-reported PA (<4.8 MET-h/week) was associated with increased MSD risk (hazard ratio (HR) = 1.07, 95% confidence interval (95%CI): 1.07-1.08).
