RESUMO

HEALTH CARE ORGANIZATION FOR 2024 OLYMPICS AND PARALYMPICS GAMES. The 2024 olympic and paralympic Games (JOP 2024) constitute the largest global festive event. While this major international gathering is primarily synonymous with celebrations, health security represents a major challenge for the French healthcare system in a highly tense national and international context. The health security of the JOP 2024 relies on close collaboration between the medical service of the organizer Paris 2024, responsible for care at the Olympic sites, and state services (SAMU, Law Enforcement, Firefighters) providing support in the event of serious health incidents or exceptional health situations (SSE). The projected impact on our healthcare structures (excluding SSE) appears moderate, as a 5% increase in hospital activity and approximately 150 additional daily emergencies are expected during the Olympic period compared to a normal summer season. In the event of a major incident resulting in a large number of casualties, state services will take over the governance of relief efforts by activating the ORSEC-NOVI and ORSAN-AMAVI plans for health response. The preparation of this health coverage involves an unprecedented mobilization of all healthcare stakeholders and is manifested by the organization of exercises at a very brisk pace.


ORGANISATION DU SYSTÈME DE SOINS POUR LES JEUX OLYMPIQUES ET PARALYMPIQUES 2024. Les Jeux olympiques et paralympiques 2024 (JOP 2024) constituent le plus important événement festif mondial. Si ce grand rassemblement international se veut avant tout synonyme de fête, la sécurité sanitaire représente un enjeu majeur pour le système de soins français, dans un contexte national et international en tension majeure. La sécurité sanitaire des JOP 2024 relève d'une étroite collaboration entre le service médical de l'organisateur Paris 2024, responsable des soins sur les sites olympiques, et les services de l'État (Samu, forces de l'ordre, sapeurs-pompiers) venant en soutien en cas d'événements sanitaires graves ou en cas de situation sanitaire exceptionnelle. La prévision de l'impact sur les structures sanitaires (en dehors de situation sanitaire exceptionnelle) semble modérée, puisque l'on attend une augmentation de 5 % de l'activité hospitalière et environ 150 urgences journalières de plus pendant la période olympique par rapport à une saison estivale normale. En cas d'événement majeur générant un grand nombre de victimes, les services de l'État prendront la gouvernance des secours par le déclenchement des plans ORSECNOVI et ORSAN-AMAVI pour la valence sanitaire. La préparation de cette couverture sanitaire fait appel à une mobilisation sans précédent de tous les acteurs de santé et se concrétise par l'organisation d'exercices à un r ythme très soutenu.

RESUMO

Informal sport is a growth area of sport participation but there has been limited examination of how informal and unstructured forms of participation may contribute to health outcomes that are important for public health. This article aims to address the current lack of data examining the health outcomes associated with informal sport participation and consider the potential role of informal sport within efforts to promote healthier communities through sport. The article seeks to broaden understanding of how informal sport participation can contribute to health outcomes, particularly with regard to increasing physical activity and enhancing mental health and social connection. The article discusses the findings of an Australian mixed-method study that draws on observation, survey, interview and focus group data to examine the prospective health and social benefits of informal sport participation for adults. The findings demonstrate that informal sport participation can contribute to physical and mental health outcomes and facilitate social connection. Analysis of the observation data enabled an examination of the economic value of informal sport in relation to the health benefits it affords. The study provides valuable evidence of the value of informal sport for enhancing community health and broadens understanding of how sport can be utilized as a health promotion resource. The article concludes by suggesting that through leveraging existing infrastructure and the self-organizing aspects of informal sport, local government and health stakeholders can harness its potential to improve public health outcomes and address health inequities.

RESUMO

With a rapidly growing sports industry worldwide, one may argue that sports industry agglomeration can play a crucial role in the economy of the sports industry. In particularly, the coupling linkage between sports industry agglomeration and economic resilience can be leveraged to promote both economic quality and efficiency. Based on data on three provinces and one city in the Yangtze River Delta region during the 2011-2020 period, this study uses the entropy-weighted TOPSIS method, coupling coordination degree model, and relative development models to explore the coupling coordination relationship between sports industry agglomeration and economic resilience in this region. The results show that: (1) Sports industry agglomeration shows an overall increasing albeit fluctuating trend with inter-provincial differences. (2) Economic resilience has steadily increased, while the economic resilience kernel density curve generally shows a "dual peaks" trend. (3) The coupling coordination between sports industry agglomeration and economic resilience remains in a fluctuating, albeit coordinated state. These findings are relevant for the integration and high-quality development of the sports industry in the Yangtze River Delta region.

RESUMO

OBJECTIVES: The development of the digital economy constitutes a key component of China's endeavors to advance towards "Digital China." The sports industry functions as a new catalyst for high-quality economic growth. This study systematically evaluated the integration between these two sectors. METHODS: First, we conducted two levels of grey relational analysis to assess their integration between 2016 and 2021. Second, we conducted a VAR analysis to determine whether their integration between 2009 and 2021 represents a causal relationship. RESULTS: At the macro level, the grey relational analysis reveals that the sports industry (grade = 0.770) ranked second among China's eight key economic sectors in terms of digital economy integration. At the meso level, a wide variation (ranging from 0.606 to 0.789) existed in the grade of integration between the digital economy and the sub-sectors of the sports industry. According to the VAR model, the digital economy does not Granger cause (p = 0.344) the growth of the sports industry. CONCLUSIONS: This study yielded two added values to the existing literature: First, there exists a sectoral imbalance in the digitization process; second, the explosive growth of the sports industry was not primarily caused by the digital economy. Accordingly, the "sports + digital" complex is still in the first wave of technological integration. We propose three policy recommendations, namely, sectoral synergistic development, overtaking via esports IP, and new economy and new regulation. Collectively, these findings provide updated insights for the digital transformation towards "building a leading sports nation" and "Digital China."

RESUMO

Background: Understanding the diverse factors influencing physical activity-related injuries is crucial for developing effective interventions that enable individuals to participate in physical activity (PA) while minimizing injury risk. Currently, research evidence on the multiple factors associated with PA-related injuries is inadequate. This study aimed to examine the associations between PA-related injuries and various biological, psychological, and social factors among first-year university students in China. Methods: We recruited first-year university students from Shantou University in Guangdong Province, China, to participate in our study. Data collection employed a structured self-administered questionnaire, gathering information on PA-related injuries, as well as relevant biological, psychological, and social factors. Binary logistic regression, using a stepwise modeling approach, was employed for the data analysis. Results: Among 1,051 first-year university students, 28.16% reported having experienced PA-related injuries in the past year. Most of the injuries reported were minor, with the knee or lower leg being the most frequently injured part of the body. Improper posture, environmental conditions, and excessive physical load were the leading causes of PA-related injuries. Multiple logistic regression analysis revealed that female students (OR = 0.67, 95% CI: 0.47-0.94, p = 0.022) had reduced odds of PA-related injuries. Conversely, high neuroticism (OR = 1.61, 95% CI: 1.07-2.41, p = 0.022), being a member of a sports team (OR = 2.09, 95% CI: 1.34-3.27, p < 0.001), PA on the wet ground (OR = 1.73, 95% CI: 1.18-2.54, p = 0.005) increased the odds of PA-related injuries. Conclusion: Our findings underscore the intricate interplay of various factors contributing to PA-related injuries. Identifying high-risk individuals based on physiological and psychological characteristics, coupled with targeted interventions addressing modifiable risk factors, is crucial for effective prevention.

RESUMO

BACKGROUND: Autistic adults and those with other developmental disabilities (DD) have increased depressive symptoms and decreased activity engagement when compared to those with no DD. Few studies explore activities related to depressive symptoms in autistic people and those with other DD during adolescence. OBJECTIVE: The objectives of this analysis were to describe depressive symptoms and activity engagement among autistic adolescents and those with other DD and no DD and explore types of activities associated with depressive symptoms, stratified by study group. METHODS: Parents of adolescents completed a multi-site case-control study of autism and other DD when their child was 2-5 years of age and a follow-up survey when their child was 12-16 years of age. Questions asked about the adolescent's current diagnoses, depressive symptoms (i.e., diagnosis, medication use, or symptoms), and engagement in club, social, sport, vocational, volunteer, and other organized activities. RESULTS: Autistic adolescents (N = 238) and those with other DD (N = 222) were significantly more likely to have depressive symptoms than adolescents with no DD (N = 406), (31.9 %, 30.6 %, and 15.0 % respectively). Lower percentages of autistic adolescents participated in activities than peers with other DD, who had lower percentages than peers with no DD. Participation in sports was associated with lower likelihood of depressive symptoms in all groups. CONCLUSIONS: Autistic adolescents and those with other DD are at increased risk for depressive symptoms and reduced activity engagement. Participation in sports may be especially important for adolescent mental health regardless of disability status. Implications for public health education and intervention are discussed.

RESUMO

BACKGROUND: The National Federation of State High School Associations provides recommendations regarding health and safety policies; however, policy development is governed at the state level. Given interstate differences in governance, the primary purpose was to describe processes that State High School Athletic Associations (SHSAAs) utilize to develop a new policy. The secondary objective was to determine what methods associations use to implement new policies. METHODS: A cross-sectional survey requested SHSAA (n = 51) representatives to report how athlete health and safety policies are introduced, revised, approved, and implemented within their state. The 22-question survey was developed to gather variables for the aims of the study. Descriptive statistics were calculated for each survey item. RESULTS: Of states who responded (n = 33), most reported a 2-committee (n = 24, 72.7%) process for developing and vetting policies, with initiation from the Sports Medicine Advisory Committee (n = 27, 81.8%), followed by an executive-level committee (n = 18, 66.7%). States reported total time from policy initiation to final approval ranged from 2 weeks to over 12 months. When a new policy was approved, most states indicated implementation began with an e-mail (n = 24, 72.7%) sent to Athletic Directors (n = 26, 78.8%). School principal or district superintendent were reported as the position in charge of compliance (36.4%, n = 12). CONCLUSIONS: Most SHSAAs use a 2-step process to write and review an athlete health and safety policy before approval. SHSAAs that require a longer policy development time could delay the implementation of important health measures. SHSAAs could consider additional communication methods to ensure information reaches all stakeholders.

RESUMO

BACKGROUND: Disparities in health outcomes among racial groups warrant investigation, even among elite athletes. Therefore, understanding the impact of race upon post-medal survival in Brazilian Olympians becomes essential. OBJECTIVE: To compare post-medal survival between white and non-white Brazilian Olympic medalists from 1920 to 1992. METHODS: This study used publicly available data for a retrospective cohort study on all Brazilian Olympic medalists from 1920 to 1992 (males only). Athletes were classified into white and non-white groups using structured ethnicity determination. Kaplan-Meier analyses computed the restricted mean survival time (RMST) for each ethnic group. A Cox proportional hazards analysis assessed ethnicity-based survival differences, adjusting for medal-winning age and birth year (p<0.05). RESULTS: Among 123 athletes (73.9% white), the mean age of medal achievement was 25.03±4.8 years. During the study, 18.7% of white and 37.5% of non-white athletes died (p=0.031). White athletes had a mean age at death of 75.10±18.01 years, while non-white athletes had an age of 67.13±14.90 years (p=0.109). The RMST for white athletes was 51.59 (95% CI 49.79-53.39) years, while for non-white athletes, it was 45.026 (95% CI 41.31-48.74) years, resulting in a ΔRMST of 6.56 (95% CI 2.43-10.70; p=0.0018). Multivariate analysis showed that non-white athletes had a higher mortality risk than did white athletes (HR 5.58; 95% CI, 2.18-14.31). CONCLUSION: Following their first medal, white Brazilian Olympians typically enjoy a six-year longer lifespan than their non-white counterparts, illustrating a marked mortality gap and health disparities among healthy individuals in Brazil.


FUNDAMENTO: As disparidades nos resultados de saúde entre grupos raciais merecem investigação, mesmo em atletas de elite. Portanto, compreender o impacto da raça na sobrevida pós-medalha em atletas olímpicos brasileiros torna-se essencial. OBJETIVO: Comparar a sobrevida pós-medalha entre medalhistas olímpicos brasileiros brancos e não brancos de 1920 a 1992. MÉTODOS: Utilizamos dados disponíveis publicamente para um estudo de coorte retrospectivo de todos os medalhistas olímpicos brasileiros de 1920 a 1992 (somente homens). Os atletas foram classificados nos grupos brancos e não brancos usando determinação estruturada de etnia. As análises de Kaplan-Meier calcularam o tempo médio de sobrevida restrito (TMSR) para cada grupo étnico. Uma análise de riscos proporcionais de Cox avaliou as diferenças de sobrevida baseadas na etnia, ajustando para a idade da conquista da medalha e ano de nascimento (p<0,05). RESULTADOS: Entre 123 atletas (73,9% brancos), a idade média da conquista de medalhas foi de 25,03 ± 4,8 anos. Durante o estudo, 18,7% dos atletas brancos e 37,5% dos atletas não brancos morreram (p=0,031). Os atletas brancos tiveram média de idade ao óbito de 75,10 ± 18,01 anos, enquanto os atletas não brancos tiveram idade média de 67,13 ± 14,90 anos (p=0,109). O TMSR para atletas brancos foi de 51,59 (IC 95%, 49,79 - 53,39) anos, e para atletas não brancos foi de 45,026 (IC 95%, 41,31 - 48,74) anos, resultando em um ΔTMSR de 6,56 (IC 95%, 2,43 - 10,70; p=0,0018). A análise multivariada mostrou que atletas não brancos apresentavam maior risco de mortalidade do que atletas brancos (RC 5,58; IC 95%, 2,18 - 14,31). CONCLUSÃO: Após a primeira medalha, os atletas olímpicos brasileiros brancos normalmente desfrutam de uma expectativa de vida seis anos mais longa do que seus colegas não brancos, ilustrando uma acentuada diferença de mortalidade e disparidades de saúde entre indivíduos saudáveis no Brasil.

RESUMO

This study investigates the positive coupling between the sports industry and tourism, exploring the ways to promote their interconnection. Under state guidance, the integration of sports industry services is facilitated to attract sports culture and tourism fairs, leveraging regional economic development advantages to enhance the industrial market appeal. The emerging leisure consumption mode of sports tourism injects vitality into the economy, fostering the core sports service industry. The coupling of the education and tourism sectors is strategically aligned with long-term national policies. Using IoT technology, this paper employs a grey relational analysis to assess the coupling between the sports industry and tourism, revealing a significant correlation. Experimental results demonstrate a positive coupling trend, likened to conjoined twins with a natural material basis and technical support. This coupling not only aligns with industry trends but also resonates with the "environmental protection era," "green era," and "ecological era," marking a pivotal aspect of industrial development. The study contributes valuable insights into the symbiotic relationship between the sports and tourism industries, emphasizing their interconnectedness and the positive implications for economic and environmental sustainability.

RESUMO

At present, the main raw material for producing graphene is graphite ore. However, researchers actively seek alternative resources due to their high cost and environmental problems. Biomass waste has attracted much attention due to its carbon-rich structure and renewability, emerging as a potential raw material for graphene production to be used in sports equipment. However, further progress is required on the quality of graphene produced from waste biomass. This paper, therefore, summarizes the properties, structures, and production processes of graphene and its derivatives, as well as the inherent advantages of biomass waste-derived graphene. Finally, this paper reviews graphene's importance and application prospects in sports since this wonder material has made sports equipment available with high-strength and lightweight quality. Moreover, its outstanding thermal and electrical conductivity is exploited to prepare wearable sensors to collect more accurate sports data, thus helping to improve athletes' training levels and competitive performance. Although the large-scale production of biomass waste-derived graphene has yet to be realized, it is expected that its application will expand to various other fields due to the associated low cost and environmental friendliness of the preparation technique.

RESUMO

Physical inactivity is a global health problem. Childhood is an opportune time to establish healthy physical activity behaviors, including the participation in organized physical activity, such as sports. We hypothesize that financial incentives can improve young people's participation in physical activity and sports. The design of the incentive and the context in which it operates are crucial to its success.

RESUMO

OBJECTIVES: A scoping review was conducted to synthesize the literature examining impact of the Children's Fitness Tax Credit (CFTC) on the physical activity (PA) of Canadian children. Specifically, we posed two research questions seeking evidence for: (1) equitable take-up (e.g., claiming, use) of the CFTC by Canadian families; and (2) effectiveness of the CFTC in promoting or facilitating PA or sport participation among Canadian children and adolescents. METHODS: A search was conducted in May 2023 of five databases (e.g., Medline, Scopus) and hand searching using terms such as children, adolescents, physical activity, sport, tax credit or taxation. Documents were included if they were data-based studies, available in English or French, and related to the research questions. They were then coded for characteristics of the document, sample, data, behaviour, and findings. SYNTHESIS: Of 318 possible documents, 7 documents revealing 26 findings were included after a full-article scan. Most of the documents were published and had a national scope. The most frequent source of data was from parental reports (62%), with the most common types of behaviour being tax claim take-up rates (31%) or PA (27%). For the two research questions, the available evidence suggests no support for equitable take-up of the CFTC or the amount claimed, and most of the findings indicated no (64%) or limited effectiveness of the tax credit (29%). CONCLUSION: The CFTC had limited to no impact in promoting PA among Canadian children, particularly for those experiencing low income.


RéSUMé: OBJECTIFS: Nous avons mené une étude de champ pour résumer la littérature scientifique sur les effets du Crédit d'impôt pour la condition physique des enfants (CICPE) sur l'activité physique (AP) des enfants canadiens. Plus précisément, nous avons posé deux questions de recherche pour recueillir des données au sujet de : 1) l'équité du recours (p. ex. demandes, utilisation) au CICPE par les familles canadiennes; et 2) l'efficacité du CICPE pour promouvoir ou faciliter l'AP ou la participation au sport chez les enfants et les adolescents canadiens. MéTHODE: En mai 2023, nous avons consulté cinq bases de données (dont Medline et Scopus) et effectué une recherche manuelle à l'aide de termes comme « enfants ¼, « adolescents ¼, « activité physique ¼, « sports ¼, « crédit d'impôt ¼ ou « fiscalité ¼. Nous avons inclus les études provenant de bases de données, disponibles en anglais ou en français et liées aux questions de recherche. Ces documents ont ensuite été codés en fonction de leurs caractéristiques, de leur échantillon, de leurs données, de leurs constats et des comportements étudiés. SYNTHèSE: Sur 318 documents possibles, 7 documents révélant 26 constats ont été inclus à la suite d'un balayage complet des articles. La plupart des documents étaient publiés et de portée nationale. La source de données la plus fréquente était les déclarations parentales (62 %); les types de comportements les plus courants étaient les taux de demande de crédit d'impôt (31 %) et l'AP (27 %). Pour les deux questions de recherche, les données disponibles n'appuient pas l'équité du recours au CICPE ou du montant réclamé, et la plupart des constats indiquent que l'efficacité du crédit d'impôt a été nulle (64 %) ou limitée (29 %). CONCLUSION: Le CICPE a eu un effet nul ou limité sur la promotion de l'AP chez les enfants canadiens, surtout dans les ménages à faible revenu.

RESUMO

Parents are held increasingly responsible for acting intensively to protect their children's health through everyday decisions and practices. We add to this scholarship by considering how organized athletic activities, an important part of the lives of many children, help parents fulfill their responsibility to protect their children's health. Through qualitative analysis of 92 in-depth interviews with parents, we attend to how parents' class shapes their articulation of the relationship between their children's health and their extracurricular involvement, considering literature on the ubiquity of intensive parenting expectations and the possibility that health behaviors and understandings constitute health-related cultural capital. Contrary to previous research, overall, we find similarities across class in parents' understandings of the health benefits of organized athletic activities. We find that parents believe organized athletic activities protect their children's health from inactivity, excess technology usage, and fatness. We do find some class distinctions. Middle-class parents, and not working-class parents, believe that their children's athletic activities will instill a passion for exercise and staying in shape and give children the experience and knowledge to control their body size and promote their well-being through their lives. This may signal a transformation in the relationship between health-related parenting and class that could maintain middle-class children's advantage if it contributes to differences in health beliefs, narratives, or practices that are differentially rewarded by important institutions such as schools, the workplace, or the medical system.

RESUMO

Low-cost and field-viable methods that can simultaneously assess external kinetics and kinematics are necessary to enhance field-based biomechanical monitoring. The aim of this study was to determine the accuracy and usability of ground reaction force (GRF) profiles estimated from segmental kinematics, measured with OpenCap (a low-cost markerless motion-capture system), during common jumping movements. Full-body segmental kinematics were recorded for fifteen recreational athletes performing countermovement, squat, bilateral drop, and unilateral drop jumps, and used to estimate vertical GRFs with a mechanics-based method. Eleven distinct performance-, fatigue-, or injury-related GRF variables were then validated against a gold-standard force platform. Across jumping movements, a total of six and three GRF variables were estimated with a bias or limits of agreement <5 % respectively. Bias and limits of agreement were between 5 and 15 % for seventeen and nineteen variables respectively. Moreover, we show that estimated force variables with a bias <15 % can adequately assess the within-athlete changes in GRF variables between jumping conditions (arm swing or leg dominance). These findings indicate that using a low-cost and field-viable markerless motion capture system (OpenCap) to estimate and assess GRF profiles during common jumping movements is approaching acceptable limits of accuracy. The presented method can be used to monitor force variables of interest and examine underlying segmental kinematics. This application is a jump towards researchers and sports practitioners performing biomechanical monitoring of jumping efficiently, regularly, and extensively in field settings.
