In this paper, 1,538 papers retrieved with the keywords "sports artificial intelligence (AI)" on the Web of Science database since 2007 were taken as the data source, and the Cite Space V software was used to visualize and analyze them. A visual knowledge graph was used to streamline the countries, institutions and authors conducting sports AI research, discipline distribution, research hotspots and development trends in the past 15 years. Subsequently, its development direction and research progress were discussed. Sports AI was widely distributed, with the US, China and the UK leading the way. The most prolific authors and teams in research on sports AI were concentrated in American universities. Their main research direction is to develop and improve smart wearable devices based on machine learning and deep learning technologies for different groups of people. Research on sports AI involved multiple disciplines, which mainly applied and referred to research methodologies and theories on engineering, computer science and sports science. It could be seen from the frequency and centrality of keywords that in the current field of sports AI, machine learning is the main direction, artificial neural networks is the main algorithm, and practical and empirical research based on data mining is the focus. The research hotspots were divided into three major clusters: physical health promotion, sports injury prevention and control, and athletic performance enhancement. How to introduce intelligent technology into sports for a perfect integration still has an arduous and long way to go. Future development requires joint efforts and participation of scientific researchers, professionals and common people. [ABSTRACT FROM AUTHOR]

While studies on World City Networks (WCNs) based on International Sports Events (ISEs) have revealed a nonwesternization evolutionary trend, few studies have focused on high-level ISEs' long-term spillover effects on promoting nonwestern host countries. This paper aims to fill these gaps by exploring the external connections of Chinese cities in each Olympic Games since 2008 deploying social network analysis and community detection methods. The results show that gateway events, such as the 2008 Beijing Summer Olympic Games and the 2022 Winter Olympic Games, rather than gateway cities, play essential roles in promoting Chinese cities' status in sports diffusion. Specifically, after the successful hosting of Olympic games, international sports federations (ISFs) witnessed Chinese cities' ability to organize ISEs; consequently, ISFs would try to select Chinese host cities considering China's rapid development and the relatively lower popularity of certain sports domestically. Additionally, as ISEs offer significant opportunities for city marketing, many Chinese cities have incorporated hosting ISEs as important urban development strategies. The promotion of the "events globalization" strategy by ISFs and the attraction measures taken by Chinese city governments for ISEs have ultimately led to a continuous increase in the number of Chinese cities and their direct external connections in ISE-based WCNs. This finding fully reveals the long-term spillover effect of high-level ISEs on promoting cities in nonwestern host countries. This further indicates that the nonwesternization trend in ISE-based WCNs may be because an increasing number of high-level ISEs, such as the Olympics and the World Cups, were held in nonwestern countries., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2024 Ou et al.

Great importance is attached to physical exercise and students' cognitive development, yet the precise mechanism linking the time duration of physical activities or sports with adolescents' cognitive development remains inconclusive. Based on the two-wave panel data of China Education Panel Survey (CEPS), this paper empirically examines the impact of daily physical exercise duration on junior middle school students' cognitive abilities, by using the two-way fixed-effect estimation. The findings reveal a nonlinear relationship, specifically an inverted "U"-shaped pattern, between daily time length of physical activities or sports and students' cognitive performance. The cognitive benefits of time investment in physical activities or sports reach the peak at approximately 0.829 h (equivalent to 50 min) per day among the teenagers in China. Furthermore, the daily time allocated to physical activities or sports affects students' cognitive performance differentially, students attending rural schools were rewarded more progressively, students of poorer physical fitness and those in good shape did not show discernible between-group differences. This study shades light on educational governance and time management, urging school administrators, parents and students to optimize the efficiency and utility of time resource invested in sports activities., (© 2024.

The article explains the economic dynamics of the sports industry with adoption of deep learning algorithms and data mining methodology. Despite outstanding improvements in research of sports industry, a significant gap prevails with regard to proper quantification of economic benefits of this industry. Therefore, the current research is an attempt to filling this gap by proposing a specific economic model for the sports sector. This paper examines the data of sports industry covering the time span of 2012 to 2022 by using data mining technology for quantitative analyses. Deep learning algorithms and data mining techniques transform the gained information from sports industry databases into sophisticated economic models. The developed model then makes the efficient analysis of diverse datasets for underlying patterns and insights, crucial in realizing the economic trajectory of the industry. The findings of the study reveal the importance of sports industry for economic growth of China. Moreover, the application of deep learning algorithm highlights the importance of continuous learning and training on the economic data from the sports industry. It is, therefore, an entirely novel approach to build up an economic simulation framework using deep learning and data mining, tailored to the intricate dynamics of the sports industry., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2024 Haishan Liu.

The formulation and implementation of a rural sports policy is an important means of promoting rural sports, improving the physical wellbeing of farmers, and enhancing the cohesion of rural communities. However, introducing such a policy faces problems in the process of specific policy practices, such as poor effective implementation, a lagging implementation effect, and goal cognitive bias. How to look at the current rural sports policy implementation blockage problem and the governance of the blockage, in order to improve the level of rural sports public service, is the focus of this paper's research. On this basis, this paper selects 56 policy texts, issued from 2002 to 2023, that are highly relevant to rural sports and have high timeliness and authority from the sports policies issued in China. Also, ROST CM6 software is used to count high-frequency words; this study then draws keyword social network mapping for the visual analysis of policy preferences and selects 20 rural sports policy texts as typical samples. Finally, a policy modeling research consistency (PMC) index model is used to evaluate the texts comprehensively and quantitatively. The results show that the overall design of China's rural sports policies is relatively reasonable. However, the consistency and effectiveness of their implementation need to be improved. Twenty representative policy texts have an average PMC index score of 5.96, with a concave index of 3.04 (which is good overall), with the highest mean value for rural sports policies at the national level. This is followed by the second highest value at the municipal and county levels, and the smallest at the provincial level. Therefore, in the future formulation and implementation of rural sports policies, a multi-dimensional rural sports policy system should be constructed. This would help to strengthen the consistency and effectiveness of the implementation of the policy system and promote the high-quality development of rural sports., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2024 Chen, Zhu, Xie, Lao and Li.)

Ultimate frisbee has gained great attention and enjoyed explosive growth in China from 2019 to 2022 (especially in 2022), but has also aroused heated controversies in cyberspace, typically in the football community. This paper explores the forms and underlying reasons for conflicts between the two sports. Through field observation, in-depth interviews, and a survey of amateur participants in both frisbee and football, the paper finds that conflicts between the two sports, which arise from ultimate frisbee's quest for legitimacy, are exaggerated as a result of the mediatization of sports. The study further revealed that Frisbee, as an alternative sport, exhibits notable cultural distinctions from football, a traditional sport. This divergence in sports culture mirrors the generational gap. Consequently, the conflict between the two sports is more of an intergenerational conflict within the realm of sports culture, reflecting the overall transformation of Chinese society.

The adoption of environmentally-friendly habits has become more crucial in the present period as a means to mitigate the rate of environmental degradation and its detrimental consequences. The augmentation of sports, exercise and physical activities has been associated with favourable health outcomes, in addition to the ability to mitigate carbon emissions resulting from vehicular transportation. Consequently, the objective of this study is to examine the influence of sports, exercise, and physical activities, along with public health expenditure, on the environmental performance of China's coastal regions throughout the period spanning from 2010 to 2019. The proposed study employs the Feasible Generalized Least Squares (F.G.L.S) and the Generalized Method of Moments (G.M.M) methodologies. Results show that participation in sports and other forms of physical activity significantly improves environmental performance in China's coastal areas. Likewise, a robust negative correlation exists between air pollution and healthcare expenses, hence favouring enhanced environmental outcomes. Nevertheless, it is important to acknowledge that economic expansion has a direct correlation with increased emissions, hence harming environmental performance. There exists compelling evidence indicating a significant impact on environmental quality resulting from the combined influence of heightened health expenditures and increased engagement in sports. This is demonstrated by the presence of an interaction term between health expenses and sports activities. The findings of this study suggest that there is a requirement to re-evaluate healthcare spending initiatives and sporting activities in order to effectively pursue carbon neutrality goals and improve environmental sustainability., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier Inc.

How to improve the success of new project development through the collection of resources in the preliminary stages of new project development is a new area of research. Given the speed and magnitude of changes in the folk sports market environment, this study analyses the impact of tapping folk tourism resources on sports projects at the project development stage. Through stratified regression analyses of 600 Chinese firms engaged in folk sports project development, this paper finds that tapping internal tourism resources positively affects the Fuzzy Front-End Performance of incremental innovative project development. In contrast, tapping external tourism resources positively affects the Fuzzy Front-End Performance of breakthrough innovation projects. The study also indicates that the speed of environmental change (SEC) positively moderates the relationship between exploring external tourism resources (ERS) and Fuzzy Front-End Performance of incremental innovation projects. In contrast, the magnitude of environmental change (MEC) negatively moderated the relationship between internal tourism resource exploration (IRS) and the FFE-P of similar projects., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2024 Yu et al.

There is no clear explanation for the extraordinary rebound in China's population mortality over the past decade. This paper utilizes panel data from 31 Chinese provinces from 2010 to 2020 to determine the distinct impacts of public sports services (PSS), public health services (PMS), and their interaction on population mortality. Empirical results show that public sports services significantly reduce mortality. Every unit increase in public sports services reduces mortality by about 2.3%. It is characterized by delayed realization. Public health services were surprisingly associated with a rebound in mortality. Further studies found strong health effect from interaction of public sports and health services. The effect was significantly strengthened in areas with fewer extreme temperatures or developed economy. The findings have important policy implications for the high-quality development of public sports and health services. It also emphasizes integration of sports and medicine and mitigates health risks associated with extreme temperatures., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2024 Cao, Cai, Gong, Bao, Hu and Tang.)

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., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2024 Hu et al.

Accurately predicting the performance in various sports is crucial in comprehending training characteristics and enhancing physical education and training processes. The increasing significance of sports in China has enhanced the interest for developing prediction models to assess athletes' sports performance, accurately. These models will greatly contribute to improving sports performance and implementing scientific training methods. This paper proposes a prediction model for athletes' sports performance using Neural Networks as the underlying framework. This research aims to enhance sports performance and scientific training by developing a reliable and effective prediction model. First, the proposed model utilizes neural network algorithms, including error backpropagation and genetic algorithms, to train and optimize the prediction model. Second, it analyzes temporal patterns, extracts statistical features, and adapts to new data by ensuring reliability and effectiveness of the proposed model. Third, this paper conducts an error analysis by comparing the prediction errors between our proposed method and traditional models to evaluate the accuracy of the prediction model. In addition, this paper conducts an error analysis by comparing the prediction errors between our proposed method and traditional models. Finally, the results demonstrate that our proposed method achieves a maximum error of 36.12%, with the highest error rate in the BP network prediction being 6.76%. Furthermore, we compared our predicted results with multiple linear regression and other existing prediction methods, and our proposed method demonstrated superior accuracy with an overall prediction accuracy of 97.6%. Our suggested solution surpasses previous approaches with much higher accuracy, reduced latency, improved recall, and increased scalability. [ABSTRACT FROM AUTHOR]

To guarantee the blue skies for the 2022 Winter Olympics held in Beijing and Zhangjiakou from February 4 to 20, Beijing and its surrounding areas adopted a series of emission control measures. This provides an opportunity to determine the impacts of large-scale temporary control measures on the air quality in Beijing during this special period. Here, we applied the WRF-CMAQ model to quantify the contributions of emission reduction measures and meteorological conditions. Results show that meteorological conditions in 2022 decreased PM 2.5 in Beijing by 6.9 and 11.8 µg/m 3 relative to 2021 under the scenarios with and without emission reductions, respectively. Strict emission reduction measures implemented in Beijing and seven neighboring provinces resulted in an average decrease of 13.0 µg/m 3 (-41.2%) in PM 2.5 in Beijing. Over the entire period, local emission reductions contributed more to good air quality in Beijing than nonlocal emission reductions. Under the emission reduction scenario, local, controlled regions, other regions, and boundary conditions contributed 47.7%, 42.0%, 5.3%, and 5.0% to the PM 2.5 concentrations in Beijing, respectively. The results indicate that during the cleaning period with the air masses from the northwest, the abatements of PM 2.5 were mainly caused by local emission reductions. However, during the potential pollution period with the air masses from the east-northeast and west-southwest, the abatements of PM 2.5 were caused by both local and nonlocal emission reductions almost equally. This implies that regional coordinated prevention and control strategies need to be arranged scientifically and rationally when heavy pollution events are forecasted., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2022.

With the development of society, the number of autistic children in China is increasing, which not only makes the family's happiness very low, but also seriously affects the development of teenagers and society. Among the symptoms of autistic children, early childhood communication skills have received extensive attention. In traditional rehabilitation training, with a lack of parents' participation, most of the training cannot arouse the interest of autistic children, so the treatment effect is not obvious. Based on this, this paper proposes the application of family sports games to improve the early communication ability of autistic children. This article aims to investigate the role of family sports games in promoting the development of early communication skills in autistic children. This paper uses the fuzzy comprehensive evaluation method to score the comprehensive ability of family sports games. The experimental results of this paper show that before the experiment, the comprehensive scores of children's communication ability in the control group and the experimental group were 18.92 and 18, respectively, which were generally low, and there was no significant difference. This shows that the communication skills of the two groups of children before the experiment are relatively poor. After the test, the children's comprehensive score of communication ability in the experimental group increased by 35.8 points, and the difference was significant, indicating that family sports games have a great impact on the development of children's communication ability.

Public sports venues serve as a crucial material medium for human athletic activities. Research on their spatial distribution holds profound implications for optimizing spatial layout and promoting human sports endeavors. This paper takes interest points of sports venues in China as research samples, employing GIS spatial analysis tools, mathematical statistics, and Geo-detector as research methods. It systematically investigates the spatial distribution characteristics and causes of sports venues in China, aiming to provide insights and references for the optimization of spatial arrangement, sustainable development, and relevant policy formulation of sports venues in the country. The results indicate that: (1) In terms of overall distribution characteristics, sports venues in China present a multi-centric agglomeration in geographical space. (2) From a regional distribution perspective, the spatial layout of these venues reveals a pattern of "more in the south, less in the north," "dense in the southeast, sparse in the northwest," and a coastal strip distribution. (3) Regarding spatial correlation, the hot and cold spot partitions of sports venues largely align with the "Hu-Line", with their spatial distribution tending towards a positively correlated pattern of high-high clustering and low-low clustering. (4) There is evident heterogeneity in factors affecting sports venues' spatial distribution. The distribution results from the interactive coupling of multiple factors, where the interaction between any two factors offers stronger explanatory power for the spatial layout of the venues., (© 2023.

The paper uses spatial panel data on the number of patents in the field of sports in each province from 2017-2022 to explore the spatial and temporal evolution process of the innovation capacity of China's sports industry and analyze its development trend based on theories related to economic geography, using exploratory spatial data analysis (ESDA) and Spatial-temporal correlation analysis research methods. The study shows that: 1. there is a large spatial regional disparity in the innovation capacity of China's sports industry, showing an obvious pattern of strength in the east and weakness in the west. 2. there is an obvious phenomenon of spatial agglomeration in the innovation capacity of China's sports industry and the agglomeration phenomenon in space is gradually increasing. 3. there is a spatial spillover effect in the innovation capacity of China's sports industry, and the inward spillover continues to strengthen mainly into Zhejiang, Fujian and Jiangsu provinces, while the outward spillover mainly goes to Guangdong, Hubei, Hebei, Hunan, Sichuan. Sports industry innovation capacity development put forward three suggestions: to promote the development of sports industry in the northwest region; to play the advantages of regional characteristics of sports industry; to accelerate the integration of neighboring regions to build the process. in order to help the high-quality development of sports industry., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2023 Chen et al.

The Internet of Things (IoT) has gained significant popularity through wearable technologies. Several IoT devices are used in educational institutions, smart homes, and security management. Their widespread use in sports training applications using IoT (WS-IoT)-based wearable sensors is noteworthy. Meanwhile, artificial intelligence (AI) has evolved rapidly, and its applications have expanded across many diverse fields. Over the past few years, China has placed greater emphasis on physical education to enhance students' physical fitness and overall capabilities. A significant number of colleges and universities have adopted artificial intelligence to transform traditional single-mode sports training methods. This paper introduces a continuous monitoring system for sports individuals using the WS-IoT. The goal of coaches is to maximize the results of athlete training across various sports events using AI technology and their sports expertise. In this study, we examine the use of AI technology in sports and assess the practical implications of its implementation. To achieve the objective function, we used a Bayesian deep classifier and deep learning algorithms that utilize adaptive optimization. Utilizing artificial intelligence in Chinese educational institutions improves training efficiency and effectiveness. The system was then rigorously tested and analyzed in terms of the quality-of-service parameters, including communication collisions and packet loss rates. It is shown that packet loss rates increase with increasing packet numbers, but collision rates remain unchanged. Furthermore, a practical application of the system in colleges and universities showed that 14.4% of the students were extremely satisfied with the use of teaching materials, 24.5% were satisfied with the materials, 30.1% were satisfied with the training methods, and 17.9% were dissatisfied.

In order to solve the problem of resource ecological compensation, this paper proposed a model of resource ecological compensation mechanism based on a rural leisure sports environment. The model is carried out in many places in China. The survey data involves 31 provinces, 10 years, and 43 indicators, with a total of 43 × 10 × 31 = 13,330 data. The preliminary basis of mechanism construction is summarized from four aspects. Finally, make full use of modern information technology to improve the network platform of the compensation mechanism, promote the efficient allocation and comprehensive utilization of ecotourism resources, and lay a solid foundation for establishing a reasonable and perfect resource ecological compensation mechanism and ensuring the long-term and stable operation of the mechanism. Through the experiment, it is found that the timely and effective publication of information can eliminate the inner estrangement between the two sides, so as to make the behavior of both sides more rational. A special information feedback department is established to deal with the opinions put forward by all compensation parties in tourism development, extract effective information, summarize and publish reasonable guidance information, and guide the compensation of both sides to an ideal balance through the feedback of this information. The effectiveness of the experiment is verified. [ABSTRACT FROM AUTHOR]

The understanding of sports event risk and Olympic sports cooperation spirit, as well as the systematic analysis and research of sports event risk management, are still in their early stages in China's sports theory circle. Institutions for developing sports talent also disregard programmes designed to increase the risk awareness and Olympic spirit of sports workers. This essay provides an overview of the concepts of sports event risk and Olympic sports cooperation spirit based on reality. This paper examines the interaction of risk management of large-scale sporting events and Olympic sports cooperation spirit from the perspective of event organization managers, using the pertinent theory of risk management and the random forest algorithm in machine learning. The experimental results show that, according to the analysis of injury occurrence according to different positions, it is discovered that forward athletes suffer the most injuries, with an average of 54 forwards in injury situations, followed by guards with an average of 43 guards in injury situations, and finally centres with an average of 38 guards in injury situations. Combining risk management for major sporting events with the cooperative Olympic sports spirit has significant practical implications. [ABSTRACT FROM AUTHOR]

Chinese traditional sports are diverse and have rich national cultural connotations. However, with the development of China's Health Strategy, modern sports such as badminton and basketball occupy most of the people's time. On the contrary, there is much less exercise for traditional Chinese sports. Therefore, this paper aims to study Chinese traditional sports under China's Health Strategy and explore its cultural soft power. In this study, participants of all ages in different regions were selected for survey research. Combined with the survey results, the soft power index model of Chinese traditional sports culture is designed. The experimental results showed that for Chinese traditional cultural projects, the cultural soft power index of chui wan was the lowest at 0.568, and the highest was 0.982 in the dragon boat culture soft power index. For each evaluation index, the cultural cognition and cultural attractiveness of Chinese traditional sports were high, but the cultural behavioral power was low. This shows that the soft power model of Chinese traditional sports culture based on the healthy China strategic environment can effectively evaluate the development of traditional Chinese sports, which also can provide suggestions for the development and inheritance of traditional Chinese sports.

With the progress of the Internet of things technology in recent years, all aspects of people's lives have also been affected. More and more people are immersed in the virtual world and ignore the real activities. According to the survey, nearly 50% of people in China are in subhealth, mainly modern diseases caused by long-term inactivity. Therefore, to form a good habit of physical exercise, we must start from an early age. Starting from the physical education teaching in primary and secondary schools and from the perspective of modern scientific and technological facilities, this paper discusses the practical sports analysis and action optimization of physical education teaching based on the perception of the Internet of things. Starting from the practice of Internet of things sensor sensing in physical education teaching, we have successively determined the multisensor motion acquisition system algorithm, motion pattern recognition algorithm, and motion energy consumption algorithm, which provides modern equipment for motion analysis and motion optimization in physical education teaching practice, which breaks the current situation that traditional teachers spend a lot of time and energy for students. Combining sports mode with sports energy consumption can not only analyze sports data accurately and in real time but also optimize and predict students' sports behavior in time. We hope to supervise and urge primary and secondary school students to exercise through technical means to improve the quality of primary and secondary school students' exercise and improve people's health through physical exercise.

Urban planning and design, with the objectives of energy efficiency and climate adaptation, is receiving more and more attention as urban energy consumption keeps rising. As technical representatives with large spans and high difficulties, sports stadia have a broad range of energy conservation and emission reduction compared with traditional buildings and have an extremely close relationship with the energy consumption of the building environment and urban microclimate, so it is necessary to study the climate adaptation design strategy of sports stadia. However, climate adaptive design has not given much thought to sports stadia nowadays. And the energy-saving strategies of sports stadia rely mostly on engineering expertise without taking into account the effect of sports stadia layout, shape, and structure on the urban microclimate. This paper investigates the energy-saving and climate-adaptive design techniques of sports stadia in the hot summer and cold winter zone of China using the layout of sports stadia as the research object. Firstly, we construct a climate adaptive design framework of sports stadia of "layout-shape-structure" based on the characteristics of sports stadia. Secondly, combined with typical examples of large-scale sports stadia in hot summers and cold winters, we establish an abstract model of architectural layout, shape, and structure based on climatic environment. In order to provide climate-adaptive design methods for sports stadia in hot summer and cold winter zones, the ventilation of the external and internal spaces of sports stadia is simulated, quantified, and compared using CFD software. The study's findings suggest that the layout of sports stadia should take into account the direction of the local wind, that the goal of low energy consumption should guide the choice of building form, and that the internal wind and temperature environment should be stabilized during construction. The study's findings can serve as a guide for comparable designs that aim to construct sports stadia with reduced carbon footprints. [ABSTRACT FROM AUTHOR]

Multiple studies have proved that participating in sports can effectively reduce adults' depression. This paper provides evidence from China by using the survey data from China Family Panel Studies (CFPS), which contains sport-types, personal characteristics, and CES-D20 depression-scale score data of 33,236 individuals. In addition to the Ordinary Least Squares regression model, we adopt the Two-way Fixed Effect and Propensity Score Matching method to alleviate the endogeneity. The empirical result shows that for every additional time of physical exercise, the depression level drops by an average of 0.152; the depression level of people who participate in sports is significantly lower than that of non-participants by 0.397 points. The lowering effect of physical activity on depression is not linear, and excessive exercise may lead to increased depression. Furthermore, heterogeneity analyses discover that with the increase of age and education, the impact continued to expand. For every increase in physical exercise of the group over 76-year old, the depression level decreased by 0.373 points; while for individuals with primary school education, their depression level decreased only by 0.124 points., Competing Interests: The authors have declared that no competing interests exist.

Fredric Jameson's cultural theory forms a crucial part of the Western Marxist theory. Jameson's postmodern cultural theory includes cultural expansion, cultural history, cultural hyperspace, cultural ideology, and so on. The cultural expansion includes the outline of popular sports culture. (1) Content: In order to further understand the acceptance of Jameson's cultural theory in China, this paper explores the communication of Jameson's cultural theory in different cultural groups, different regions, and different communication channels in China based on the questionnaire survey in a larger span of social groups. Meanwhile, based on Jameson's theory, it also reveals that sports is an effective way to achieve national stability and rejuvenation. Mainstream culture not only leads fashion, educates the people, serves society, and promotes development but also has the common characteristics of mass culture, commerce, entertainment, popularity, and media dependence. Sports is both mainstream culture and mass culture, which is the positive energy shared by both. (2) Methods: In order to understand the special meaning of Jameson's cultural theory and its influence on Chinese mass culture and sports, this paper systematically explains Jameson's cultural theory and gives a critical explanation to Jameson's cultural theory, different regions, and different communication channels in China based on the questionnaire survey in a large span of mass culture and sports groups. (3) Results: the majority of readers who buy and read Jameson's cultural works are mainly 25-35 years old with high educational background. The top three regions for the number of consumers who buy his papers and books are Zhejiang, Hubei, and Guangzhou; the top three regions in the number of understanding Jameson's cultural theory are Beijing, Shanghai, and Shenzhen; 41.62% of the respondents only know Jameson's name but have not been exposed to his work; and 34.59% of the respondents have learned about his work through news feeds. (4) Conclusion: the influence of Jameson's cultural theory on Chinese mass culture and sports community is on the rise. Systematic sorting and interpretation of Jameson's cultural knowledge can provide support for Chinese mass culture and mass sports culture to carry forward socialist cultural thoughts., Competing Interests: The author declares that there are no conflicts of interest regarding the publication of this paper., (Copyright © 2022 Xia Chen.)

With the rapid development of China's economy, people are eager for an effective way to relieve work pressure and strengthen their health at the same time. Outdoor sport is one of the best choices for people. However, the amount of recommended data on the network is very large. As a result, when people understand outdoor sports through the network, they cannot effectively obtain the information they want. This is the problem of "information overload," and personalized recommendation system can effectively alleviate this problem. In order to effectively recommend outdoor sports to users, a useful attempt was made in the personalized recommendation system for outdoor sports in this paper. The specific work of this paper is as follows: firstly, the current situation of outdoor sports in China was summarized, and the related technologies of the recommendation system were studied, including user modeling technology, recommendation target modeling technology, and recommendation algorithm. In order to obtain better recommendation effect, this paper proposes to mix user-based collaborative filtering recommendation algorithm, project-based collaborative filtering recommendation algorithm, and content-based recommendation algorithm. The hybrid algorithm adopts the way of feature expansion and weighted combination. Firstly, the hybrid model (model 1) of user-based collaborative filtering recommendation and content-based recommendation is obtained. Secondly, the hybrid model (model 2) based on project collaborative filtering recommendation and content-based recommendation was obtained. Finally, model 1 and model 2 were combined together to get a hybrid model with better final recommendation effect. For the common cold start problem in the recommendation system, the system adopts content-based recommendation algorithm to solve it., Competing Interests: The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2022 Hao Lei et al.)

Aim: This paper analyzes the adaptive changes that take place in mature and elderly women with different track records in social sports in order to develop health and rehabilitation techniques based on personalized and groupwise approaches. Methods: This longitudinal study was conducted between 2009 and 2019 in Zhengzhou, China. The sample consisted of 24 mature and elderly women (45–65 years old) in the experimental group (regular social sports) and 40 women of the same age who did not exercise (control group). The experimental group received physiotherapy twice a week. The sessions were scheduled for 10 a.m. and lasted for 3 h. The functional status of cardiovascular system parameters (blood pressure, heart rate) was measured. In addition, the physical working capacity (PWC 150), as well as the coefficient of body adaptation to stress and the Robinson index (the amount of oxygen required by the human body to function) were estimated. Results: Women from the experimental group maintained stable coefficients of adaptation during all 10 years over which the study was conducted. Women with a long track record (up to 10 years) revealed a slight increase in the body's functional capacity (P ≤ 0.05 with control). More than 50% of the women in the experimental group had cardiovascular measurements within or above the normal range, whereas the opposite was true in the control group. Conclusions: The longitudinal study revealed upward trends of physical working capacity indicators, which can slow down involutional changes in the body. In some cases, the body's functional capacity may be improved. Geriatr Gerontol Int 2023; 23: 98–102. [ABSTRACT FROM AUTHOR]

With the accelerating rate of population aging in China, the health of the elderly has received more and more attention and has become one of the most important issues in the elderly care industry. Because of insufficient research on the personal health of the elderly, the value of medical examination data cannot be fully exploited, many physical indicators have a certain impact on overall health or heart health, and there are few studies on heart health assessment. This paper proposes a deep learning-based elderly management analysis method of human exercise health level, using the exercise health management model to evaluate the heart health level of the elderly. Firstly, the indicators to measure heart health are proposed through traditional expert knowledge and personal health index to analyze heart health. Through dynamic assessment, predict the heart health status at the next time point, analyze possible heart diseases, and provide corresponding methods for the health of the elderly, which helps improve the physical health of the elderly. Quality of life provides assistance to meet the needs of improving the health of older adults., Competing Interests: The author declares that there are no conflicts of interest., (Copyright © 2022 Liping Xiao et al.)

The Chinese sports industry encompasses both the secondary and tertiary sectors of the country's economy. More prominent are the issues of unbalanced industrial structure development, mismatch between supply and demand, and rapid expansion of the sports goods manufacturing industry. This paper first employs the literature method to investigate the dynamic mechanism and promotion strategy of China's sports industry's green development. In order to improve the accuracy of data mining and quantitative analysis in the sports industry, this paper proposes a time series-based model for the analysis of sports industry data. Utilizing the global steady-state feature fusion method, the statistical and quantitative fusion analysis method, and the fuzzy analytical control method, accurate mining of sports industry data is achieved. The simulation results demonstrate that this method has greater precision and a higher degree of feature matching for sports industry data mining, thereby reducing the disturbance error of sports industry data mining., Competing Interests: The authors declare that there are no conflicts of interest., (Copyright © 2022 Qi Huang et al.)

Regular competitions on a bigger size and level are referred to as sports events. The World Cup, the Olympics, Formula, the NBA, and many intercontinental sports events and World Championships of various individual sporting organizations, among others, are among the world's largest and most significant sporting events. In China, there are also specific live sporting event websites that broadcast weekly sporting events. The purpose of this paper is to study the integrated development mechanism for the sustainable development of natural ecotourism and sports events. For this reason, this paper proposes research and analysis on its industrial integration method and industrial integration path, and it has an in-depth understanding of the sustainable development model. At the same time, relevant experiments are designed in the experimental part to explore the impact of sports events and natural ecotourism in the development process.

Community amateur sports training equipment is necessary to ensure the development of national fitness activities. It is found that the design concept of community public sports space in China is not perfect, the structural layout is not reasonable, the stock space is not optimized, and the resource allocation is not balanced. In particular, there is a lack of indoor fitness facilities and sports venues in the community, and the people's "fitness where to go" is still a difficult problem. In the smart city construction, the resource integration and optimization of community amateur sports training facilities have also been further developed. Considering various influencing factors, this paper establishes a location model of community amateur sports training facilities with the least total cost and convenience. Aiming at the practical optimization problem with high complexity, an improved adaptive weight multiobjective particle swarm optimization (PSO) model is proposed. These parameters in the algorithm were adjusted dynamically, which balanced the overall search ability and partial improvement ability of the PSO algorithm and completed the optimal scheduling of community amateur sports training equipment configuration while ensuring the optimal global solution. Experimental results show that the algorithm's efficiency and searching ability have been further promoted. It also has an excellent performance in solving the complex location problem of community amateur sports training facilities., Competing Interests: The authors declare that there are no conflicts of interest., (Copyright © 2022 Yuehong Wan and Hong Tang.)

Physical education curriculum has been paid more and more attention by teachers and parents, and having a healthy body is the foundation. School sports competition is also more and more concerned by major researchers, and scholars have produced in-depth research and analysis of sports competition results prediction because prediction results can better let teachers carry out appropriate sports training for students, so as to achieve the best learning effect. The construction of the prediction model and whether the performance and universality of the model after construction are suitable for predicting sports competitions have also become a major research point. Deep neural network is a complex network method to analyze the structure of the human brain, which plays a core role in the field of sports planning and performance prediction and can know the future performance of athletes or students in advance in sports competitions. This paper establishes the autoregressive summation model prediction model, the complex neural network prediction model, and the improved complex neural network prediction model. It is concluded that only the improved BP neural network model has a remarkable effect on performance prediction, and the prediction value obtained by this prediction model can reduce the systematic error of prediction, so that it can better infer the performance prediction of sports competitions in China and plan which sports events are suitable for which prediction model., Competing Interests: The author declares that there are no conflicts of interest regarding this work., (Copyright © 2022 Jin Xu.)

With the rapid development of social economy and the change of ideology, people are increasingly enthusiastic about participating in sports events. How to make better use of the existing massive network data of sports events to solve the overload of information circulation of sports events has become a potential application problem to promote the development of sports information digitalization. Based on this problem orientation, this paper chooses to study the common characteristics of the current Internet data of sports events and the corresponding and applicable event recommendation technology and constructs feasible event recommendation model as the main direction of solution. The competition information system is the core technology system of the games and the central nervous system of the games. By summing up the previous high-level comprehensive games, the competition information system should serve the competition, command, media, and the public. The smooth construction and stable operation of the perfect design of the competition information system will reflect the organization level of the games and guarantee the success of the games. At the same time, it has certain guiding significance for the design of the competition information system of the large-scale comprehensive games in China in the future., Competing Interests: The authors declare that they have no conflicts of interest or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2022 Yang Wen and Feng Wang.)

With the vigorous development of the Chinese economy and people's pursuit of quality, sports activities of people pursuit are no longer limited to simple physical exercise, but a way that pursues higher-quality sports tourism. As a new industry, it cannot guarantee that sports tourism will be accepted by all people, and it will be limited by geographical, economic, time, and other conditions. The participation number of Chinese sports tourism is more concerned by organizers or operators. Predicting the participation number of sports tourism based on the knowledge discovery method is meaningful and economical work. In this paper, a variety of sports tourism data are classified by clustering method, and the categories with similar characteristics are classified. Then, the convolution and long short-term memory hybrid neural network are used to extract the spatial and temporal information of sports tourism characteristics, which completes the prediction of Chinese sports tourism categories. The research results show that the clustering method has high accuracy for the classification of sports tourism categories, and the weights occupied by the categories are relatively uniform. The ConvLSTM neural network also has obvious advantages in predicting Chinese sports tourism methods. The largest error is only 2.89%, and the correlation coefficient also reaches 0.98, which is enough to be trusted for the prediction of Chinese sports tourism categories., Competing Interests: The authors declare that they have no conflicts of interest in the study., (Copyright © 2022 Libin Qi and Yaohan Tang.)

High-intensity emission controls were implemented in Nanjing and in 8 surrounding cities to ensure good air quality during the 2014 summer Youth Olympic Games (YOG). An Aerodyne soot-particle aerosol mass spectrometer (SP-AMS) was deployed at a downwind site of downtown Nanjing to investigate the chemical composition, sources, and size distribution of submicron aerosols (PM 1 ), in response to emission control policies. However, results show that emission controls played a negligible role in reducing PM 1 concentration during the YOG period, yet primary precursors such as NO x and SO 2 were decreased by 10-20%. Low wind speed, high relative humidity, and high ozone (O 3 ) concentration likely play a significant role in the production and accumulation of the oxygenated organic aerosol (OOA) and the secondary inorganic aerosols (SIA) in summer Nanjing. We propose that long-term regional emission reduction could be a solution for future air pollution mitigation strategies in downwind cities of the YRD region, and that seasonal meteorological characteristics in a specific region should be considered before emission control policies are made., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2021 Elsevier B.V.

Health literacy refers to an individual's ability to acquire and understand health information and use it to maintain and promote his own health. In physical education, teenagers' physical health literacy refers to teenagers improving their physical quality and comprehensive ability through physical training. The development of youth sports activities mainly depends on school physical education. Without the main channel of school physical education, it is difficult to achieve the strategic goal of improving youth health literacy. In order to effectively promote the cultivation of teenagers' health literacy, it is necessary to establish a scientific and reasonable physical education system according to the cultivation characteristics of teenagers' sports health literacy. Constantly strengthening the supervision of teenagers' physical exercise and paying attention to cultivating teenagers' sports habits are of great significance to the cultivation of teenagers' sports health literacy and their future study and development. Based on this, this paper expounds and analyzes the concept, necessity, and training path of teenagers' sports health literacy under the background of healthy China., Competing Interests: The authors declare that they have no conflicts of interest., (Copyright © 2022 Yong Jiang and Guangjian Xu.)

As an important means of communication, sports public opinion has been paid more and more attention by the country. This article will focus on the emergency events of sports events as the main object and research and analysis of the communication function and law in the public opinion of sports events and analyzes the characteristics of public opinion communication. This paper holds that the media play the "should be" roles in different periods, such as network public opinion monitoring and early warning, public opinion information processing and interpretation, consensus builder highlighting the mainstream, and introspection of public opinion events, and there is a media role cycle in the secondary public opinion period. Spreading law of public opinion in sports events in China: trigger-conduction-outbreak mechanism. At present, the diversified interactive mode of sports events in China makes the communication environment of public opinion in sports events more and more three-dimensional and multidimensional, and it is also convenient for us to make better use of the current regulation means of public opinion in sports events. Sports network public opinion can easily go to "post-truth." In order to strengthen the monitoring of sports public opinion and improve the ability to respond to network public opinion, using interdisciplinary thinking, this paper proposes a network public opinion guidance strategy for sports events. The experiment is aimed at the disadvantage that the trend of sports public opinion analysis and tracking is not clear. The optimization method is proposed, and the accuracy is improved by 87.5%.

In order to fully implement the new development concept, bring into full play the potential of sports development, and maintain the resilience of China's sports development. This paper studies the resilience evaluation and spatial correlation of Chinese sports development under the new development concept. First, we constructed Resilience Evaluation Indexes System for Sports Development in China based on the analysis of the resilience features of sports development and the DPSIR model, which is from the five aspects of "driving force – pressure – state – influence – response." Second, used Coefficient of Variation and Technique for Order Preference by Similarity to an Ideal Solution (TOPSIS) Method to measure the resilience level of sports development in 31 provinces in China from 2013 to 2017. Then, we introduced the obstacle degree model to identify the obstacle factors that hinder the resilience of Chinese sports development in different periods. Finally, we used the global and local Moran indexes to analyze the spatial correlation of China sports regional development. The results showed that: (1) overall, the development level of sports resilience in 31 provinces in China showed an upward trend from 2013 to 2017, while some provinces showed obvious fluctuations. (2) The obstacles to the development of sports resilience in China mainly include sports scientific research equipment, the number of national fitness monitoring stations, the number of national fitness centers, the full-time equivalent of (R&D) personnel, and the number of sports scientific research projects. The response subsystem is the main obstacle factor that affects the improvement of the resilience level of sports development in China. (3) There is a positive spatial autocorrelation between the resilience level of sports development and regional spatial distribution, and the correlation shows a weakening trend, and the internal difference is significant. Finally, we concluded that we must take the new development philosophy as the guiding principle. First, we should stick to innovation-driven development to fully upgrade the resilience of China's sports development. Second, we should adhere to the principle of coordinated development to promote the overall and balanced development of sports. Lastly, we should promote shared development so as to deliver benefits for all in an equal way. [ABSTRACT FROM AUTHOR]

Sport trade frictions have continued to evolve and escalate, which has a great impact on sport academic cooperation. In order to objectively assess the impact of sports scholarship on China and provide evidence to support future changes in sports academic cooperation, this study takes 269,647 academic papers produced by sports alone from 2010–2018 as the research object and integrates explicit, implicit, and performance information contained in the paper output to construct a multidimensional matrix assessment framework. The horizontal dimension splits the collaborative research output into three mutually exclusive subsets: China-led collaborative research, sport-led collaborative research, and bisectional collaborative research; the vertical dimension systematically analyzes the characteristics of collaborative sport academic research in terms of participants, research content, and research level. The purpose of this study is to characterize the role and status of academic cooperation between the two countries through a long period, large sample, and multidimensional perspective, to make an objective assessment of the impact of academic cooperation between the two countries, and to provide evidence to support a reasonable response to the impact of changes in the relationship between the two countries on academic cooperation.

Like the Chinese nation, China's national traditional sports culture has a long history and is a treasure of Chinese national culture, reflecting the life, customs, wisdom, and pursuit of the people of all ethnic groups in China. The dissemination of national traditional sports culture is not only a necessary method for our country's cultural export but also a necessary means to maintain the diversity of world sports culture. However, there are still serious deficiencies in the dissemination of national traditional sports culture in our country, and some traditional national sports cultures are not even known to the public. Starting from the two communication methods of sports events and network communication, this paper studies the three mature national traditional sports cultures of martial arts (Wushu), Go, and Chinese chess and proposes a quantitative method for communication methods and communication effects. We further analyze the role of national traditional sports culture in cultural communication. [ABSTRACT FROM AUTHOR]

Introduction: Athletes' mind wandering during competition has positive and negative effects. The purpose of this study was to explore the reason for these bidirectional effects. Methods: We recruited 51 athletes from China to take part in semi-structured interviews in which we explored their experiences of mind wandering in competition. We used grounded theory combined with systems thinking to complete the data analysis and theoretical construction. Results: Results showed that the influence of mind wandering on sporting performance was dynamically influenced by "mind wandering source," "competition anxiety," "content of mind wandering," "attentional resources" and "attentional control," resulting in our development of the theory of "mind wandering in sporting performance (MWSP)." The above factors determine how mind wandering occurs and how it affects the competition. Discussion: Although the occurrence of mind wandering during competition has positive effects, its negative effects cannot be ignored, which may lead to athletes losing the race (costs over benefits). Potential strategies focusing on the mitigation of negative effects and promotion of positive effects of mind wandering are discussed. [ABSTRACT FROM AUTHOR]

Employing a grounded theory approach, this study conducts interviews with 30 scholars and government officials actively involved in extensive study and practical endeavors within the domains of Sport City and sports events. The inquiry aims to elucidate the factors driving the promotion of the construction of Sport City facilitated by hosting major sports events. The results indicate that major sports events demonstrate a "cumulative effect" in fostering the construction of Sport City. Influential factors encompass the function of Sport City, the economy of Sport City, the resident well-being of Sport City, and the soft power of Sport City. Furthermore, the promotional influence of hosting major sports events on one facet of Sport City positively impacts the development of other facets. [ABSTRACT FROM AUTHOR]

Objectives: The China sports lottery contributes to sports and welfare causes. This study aims to construct a macro forecasting model supporting its sustained growth aligned with Vision 2035. Methods: The modeling employed a distributional regression. Sales data of the China sports lottery from 2011 to 2022 were chosen as the response variable, alongside various macro- and event-level explanatory factors. Results: A gamma distribution best fit the data. In the stable model spanning 2011–2019, urbanization, population dynamics, and FIFA emerged as significant contributors (Chi–square p < 0.05) to the location shift parameter. These three factors retained their significance in the 2011–2022 shock model, where shock itself notably impacted sales (p < 0.001). Utilizing the shock model, we simulated the trajectory of the China sports lottery up to 2035. China's demographics changes are poised to create structural headwinds starting in 2026, leading to an anticipated decline in sales driven by population shifts from 2032 onward. However, the FIFA effect is projected to continue fortifying this sector. Conclusions: Beyond offering original insights into the sales trajectory until 2035, specifically concerning new urbanization, negative population growth, and the FIFA effect, this macro forecasting framework can assist in addressing the policy priority of balancing growth with risk mitigation. We recommend policymakers connect market development with mass sports, potentially garnering a dual boost from the growing population of older consumers and the inherent benefits of a "FIFA (mass sports)" effect. A people-centered approach to the China sports lottery could significantly contribute to the long–range objectives of achieving common prosperity outlined in Vision 2035. [ABSTRACT FROM AUTHOR]

Background: The "Double Reduction" policy published in China provides a new opportunity to increase youth sports. Based on the perspective of parents' influence on their children, this study aimed to explore the impact of parental awareness of the "Double Reduction" policy on youth off-campus sports. Methods: This study was conducted empirically through a nationwide sample survey to analyze the relationship between parental awareness of the "Double Reduction" policy, parental education anxiety, and parental attitudes toward children's participation in sports and youth off-campus sports to construct and verify a conditional process model. Results: Parental awareness of the "Double Reduction" policy had a significant positive impact on their children's off-campus sports (β = 0.103, SE = 0.018, P < 0.01), but had a significant negative impact on parental education anxiety (β = -0.305, SE = 0.032, P < 0.01) which showed a significant negative effect on their children's off-campus sports (β = -0.114, SE = 0.011, P < 0.01) and played a significant intermediary role between parental awareness of the "Double Reduction" policy and children's off-campus sports (β = 0.031, 95%CI: 0.020 ~ 0.044). All dimensions of parental education anxiety showed different characteristics with only academic achievement anxiety (β = 0.034, 95%CI: 0.021 ~ 0.047), parent–child interaction anxiety (β = 0.027, 95%CI: 0.014 ~ 0.038), and learning attitude anxiety (β = 0.024, 95%CI: 0.015 ~ 0.033) presenting significant mediating effects. The interaction between parental education anxiety and parental attitudes toward children's sports significantly positively impacted youth off-campus sports (β = 0.008, SE = 0.001, P < 0.01). The moderating role of parental attitudes toward their children's participation in off-campus sports, indicating it was significant (95%CI: 0.005 ~ 0.011) along the pathway of parental awareness of the "Double Reduction" policy to parental education anxiety to youth off-campus sports. Conclusions: Parental awareness of the "Double Reduction" policy has a positive impact on youth off-campus sports. Parents' anxiety about their children's academic achievement, parent–child interaction anxiety, and learning attitude anxiety mediate in the process model. Parental attitudes toward sports can magnify the relationship between their education anxiety and youth off-campus sports. [ABSTRACT FROM AUTHOR]

This study explores complex relationships between the formation and development of traditional sports and games (TSGs) and the natural environment by adopting a mixed method of two studies. First, taking 1356 TSGs as cases, Study 1 uses spatial analysis to explore the representation, connotation, and source of the relationship between TSGs and natural environment factors. Second, Study 2 uses grounded theory to analyze 149 official declaration documents of TSGs and extracts 36 initial concepts, 12 subcategories, and 4 core categories, from which a theoretical framework of the formation process model of TSGs is constructed. The findings illustrate that the formation and development of TSGs are not completely determined by the natural environment but are derived from a combination of factors such as survival values, beliefs, attitudes, and the natural environment. On one hand, when the natural environment is considered an external factor of society, TSGs are directly affected by it. On the other hand, when the natural environment is considered an internal factor of society, it can only interact with people's beliefs and attitudes and indirectly accelerate or delay TSG formation and development. Research results provide both theoretical and practice implications in the safeguarding of TSGs. [ABSTRACT FROM AUTHOR]
