These updated guidelines reflect advancements in cardiology and sports medicine and introduce clear class of recommendations and levels of evidence for assessing athletes with heart disease. This document focuses on the differences between the 2023 and 2017 versions, particularly regarding athletes with arrhythmias. The guidelines integrate new scientific evidence, including modifications to criteria for specific arrhythmic conditions like Wolf-Parkinson-White (WPW) Syndrome, Brugada Syndrome, long QT syndrome (LQTS), and premature ventricular beats (PVBs). Updates on the return-to-play timing after successful catheter ablation are also included. Key updates include the revised arrhythmic risk thresholds for WPW syndrome; these guidelines also expand recommendations for asymptomatic pre-excitation cases. In Brugada Syndrome, eligibility remains dependent on the presence of malignant arrhythmias and genetic risk factors, with scoring systems to aid risk stratification. For LQTS, eligibility is reconsidered for asymptomatic individuals with a negative phenotype and a positive genotype, with beta-blocker use. Additionally, the management of PVBs is refined, with new criteria for further investigation and risk assessment. COCIS 2023 introduces a more nuanced, evidence-based approach to the eligibility of athletes with arrhythmias. The guidelines provide clinicians with detailed recommendations for managing a variety of arrhythmic conditions. As scientific research advances, these guidelines will continue to evolve, ensuring safe athletic participation for individuals with cardiovascular conditions.</p>","PeriodicalId":17013,"journal":{"name":"Journal of Sports Medicine and Physical Fitness","volume":" ","pages":"826-833"},"PeriodicalIF":1.2,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143674118","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study explores Caribbean and Latin American dances (CLADs), which highlight rich cultural heritages and offer significant health benefits. Through a scoping review, we synthesized findings from multiple studies on the physiological and psychological impacts of CLADs, both in competitive and recreational contexts. Our literature search, conducted across Google Scholar, PubMed, and Web of Science, identified 476 potential articles, of which 27 were selected for detailed analysis. These studies revealed that CLADs enhance motor coordination, self-awareness, body control, balance, and memory. The physical demands of these dances improve posture, flexibility, and cardiovascular health, comparable or superior to other forms of exercise. Specifically, studies demonstrated significant improvements in postural control, leg strength, and energy expenditure. Psychologically, dance interventions reduce symptoms of depression, anxiety, and stress, while boosting self-efficacy, motivation, and social cognition. The social and enjoyable nature of dance fosters mental well-being and cognitive function, especially in group settings. Despite challenges in adherence to physical activity, the intrinsic enjoyment of dance enhances participation rates and amplifies health benefits. The implications of these findings suggest that integrating dance into regular physical activity routines offers a holistic approach to health, addressing both physical and mental aspects.
