Mental health problems of children and adolescents have become a major challenge for global public health and education systems.Traditional single-dimensional interventions are increasingly insufficient to meet the diverse and individualized psychological needs of children and adolescents.Multidimensional exercise models offer strong scientific grounding，comprehensive system design，and high adaptability，yet their dynamic mechanisms and implementation paths remain unclear.This study systematically reviews the etiological foundations of mental problems of children and adolescents and the theoretical basis of exercise-based interventions and proposes a multidimensional exercise intervention framework built around five core dimensions：skill structure，movement context，spatial ecology，energy metabolism，and social interaction.It further articulates four dynamic mechanisms：precise policy implementation，individual adaptation，dynamic regulation，and systemic integration.Accordingly，it constructs a strategic system characterized by goal-oriented screening as the prerequisite，multidimensional combination as the core，and dynamic feedback together with social support as the guarantee.This system enables precise design，dynamic optimization，and ecological coordination of exercise-based interventions，thereby providing both the dynamic foundation and implementation paths for shifting the mental-health promotion from “experience orientation” to a “structure orientation”.

Intelligent sports services that promote the physical health of adolescents are in line with the trend toward deeper integration of digital technology and sports education and address the persistent challenge of improving adolescents’ physical health. Using literature review and logical analysis， and drawing on the social ecological model， this study clarifies the functional positioning of intelligent sports services for promoting the physical health of adolescents along the logic of “scenario reconstruction， data-driven， and model innovation”. It then constructs an operational framework that monitors health risks through intelligent sports-medicine integration services， matches intervention supply and demand through tailored exercise prescriptions， and enhances the collaborative effectiveness through connected intelligent sports communities. The study also examines the practical limitations of this framework in implementation， such as data barriers and privacy conflicts， algorithm black boxes and scenario virtualization， lagging coordination mechanisms， and a shortage of interdisciplinary teacher. Based on this， the following practical strategies are proposed: strengthening the foundation of data security to improve adolescent health； optimizing algorithm logic and scenario adaptation to enhance the scientific validity of intelligent interventions for adolescent development； breaking down cross-departmental administrative barriers to enhance the sustainable governance of sports， medicine and health for adolescents； and innovating the training pathways to ensure the professionalism of adolescent health promotion.

Advancing competitive basketball through the new whole nation system is essential for China’s basketball development to enter a high-quality growth phase.This study employs literature review，logical analysis and field survey to examine the internal logic，practical obstacles and advancement paths of high-quality development of competitive basketball under the new whole nation system.It finds that the new whole nation system demonstrates strong compatibility with the development of China’s competitive basketball.This framework can fully activate market entities，coordinate multi-stakeholder governance and optimize resourceallocation structures，so as to drive the evolution of competitive basketball toward modernization characterized by openness，efficiency，integration and intensification.However，current challenges such as institutional issues，organizational deficiencies，talent shortages，and funding extensiveness hinder the high-quality development of China’s competitive basketball.Accordingly，this study proposes the advancement paths under the new whole nation system：improving the institutional system of competitive basketball development to drive the open reforms，deepening management system innovation to enhance collaboration and governance efficiency，strengthening talent team construction to boost resource integration and innovation capabilities，and mobilizing social resources and capital vitality to optimize allocation for sustainable growth.

Empowering physical education evaluation reform with digital intelligence technology is a crucial measure to enhance students’ physical fitness.By using literature review and logical analysis，and focusing on students’ physical fitness，this study explores the connotation value and practical difficulties of deepening physical education evaluation reform through digital intelligence technology，and propose relief pathways.The study suggests that the failure to form an effective empowerment loop with digital intelligence technology，along with superficial data mining in result evaluation；the relatively weak application and implementation effect of digital intelligence technology，as well as inadequate digitalization in process evaluation；the insufficient interpretation and utilization of data results，together with unsmooth transformation of value-added evaluation data；and the limited ability of digital intelligence technology to avoid subjective bias alongside a lack of objectivity and fairness in comprehensive evaluation results.Based on this，the following mitigation measures are proposed:deeply exploring the data value of physical education result evaluation to enhance the enabling role of digital intelligence technology；deepening the practical application of digital intelligence technology to improve the digitalization level of physical education process evaluation；enhancing the ability to analyze and utilize data resources to improve the conversion efficiency of value-added evaluation data for physical education；standardizing the subjective judgment weights under digital intelligence technology to ensure the objectivity and fairness of comprehensive physical education evaluation.

Through the single-case research method，this study，taking the 2025 Jiangsu Football City League as the research object，constructs an analytical framework of “cultural symbol generation—collaborative communication—value transformation” to systematically explore the internal incentives for local mass sports events attracting extensive attention and the realization mechanism to move from short-term flow to sustainable development.It concludes that the Jiangsu Football City League establishes a foundation for emotional resonance by excavating the local culture； promotes the collaborative linkage among the government，media，platforms，and the public to form a fission-style communication effect； and transforms flow into the accumulation of economic，cultural，and social capital to form a continuously strengthening positive feedback mechanism.On this basis，from five dimensions of governance collaboration，cultural empowerment，technological application，content co-creation，and institutional guarantee，this study proposes collaborative communication pathways for mass sports events，aiming to provide references for unleashing the potential of sports consumption and promoting the high-quality development of China's sports industry.

Coaches in primary and secondary schools serve as a pivotal support for the development of school sports and the diversified cultivation of reserve talents for competitive sports in the new era. Employing the methods such as literature review， logical analysis， field investigation and in-depth interviews， this study explores the realistic demands， advancement dilemmas， and practical paths regarding the high-quality development of coaches in primary and secondary schools in the new era. It suggests that the high-quality development of coaches in primary and secondary schools in the new era responds to the realistic demands of implementing the “Health First” educational philosophy， deepening school sports reform， serving the strategy of building a leading sports power， revitalizing sports human resources， and leveraging the advantages of differentiated schooling. However， currently there are still advancement dilemmas including： fragmented management systems and conflicting goals leading to weak collaboration between sports and education； scarcity of staffing quotas and restricted position settings resulting in insufficient team stability； lack of evaluation systems and narrow promotion channels hindering career development prospects； insufficient salary packages and incentive mechanisms weakening position attractiveness； and conflicts in educational philosophies alongside shortcomings in teaching abilities constraining educational effectiveness. Accordingly， the following practical paths are proposed： improving collaborative mechanisms to clarify administrative affiliation and responsibility boundaries； innovating employment systems to resolve staffing quota bottlenecks and position restrictions； reforming evaluation systems to smooth promotion channels and expand development space； perfecting salary systems to strengthen performance incentives and guarantee benefits； and deepening professional training to enhance educational philosophies and coaching abilities.

Using literature review and logical analysis，this study focuses on movement education and preschool physical activities in the context of building an education power.By examining the connotations of movement education and preschool physical activities，it explores the theoretical coupling logic of integrating movement education into preschool physical activities.On this basis，it analyzes the practical problems and proposes pathways for implementation.The findings suggest that integrating movement education into preschool physical activities in the context of building an education power can achieve theoretical coupling in terms of objectives，processes，and mechanisms.However，structural，procedural，and developmental contradictions persist.Accordingly，drawing on embodied cognition theory，practical pathways are elaborated for integrating movement education into preschool physical activities： deepening the structural alignment between implementation vehicles for activities and movement education’s objectives；enhancing the pedagogical coherence between educators’ competencies and the implementation of movement education；and optimizing needs alignment between young children’s individual differences and movement education standards，thereby promoting high-quality development of preschool physical activities in China.

As the core business format of sports industry，sports events play an indispensable role in promoting the integrated development of culture，sports and tourism in China.Based on the theory of spatial production，this study constructs an analytical framework of “institution-economy-society-technology”，selects Jiangsu Football City League （JFCL） as the research sample，deconstructs the local practice of mass sports events in promoting the integrated development of culture，sports and tourism，and proposes promotion paths.It suggests that the integration of culture，sports and tourism driven by mass sports events is a process of realizing cultural value manifestation，sports vitality release，and tourism attraction enhancement through the deep interaction and innovative reorganization of industrial elements in a specific time and space.Local practice shows that in the policy space dimension，JFCL provides basic guarantees for the integration of culture，sports and tourism through policy coordination and departmental linkage； in the economic space dimension，JFCL provides core impetus for the integration of culture，sports，and tourism by stimulating the vitality of market entities and expanding consumption scenarios； in the social space dimension，JFCL provides emotional bonds for the integration of culture，sports and tourism through cultural identity and community aggregation； in the technological space dimension，JFCL provides platform support for the integration of culture，sports and tourism through digital communication and traffic monetization.Based on the above，promotion paths are proposed to strengthen the top-level design of mass sports events，to expand the consumption scenarios of mass sports events，to enrich the cultural connotation of mass sports events，and to promote technological innovation of mass sports events.

Concepts constitute the logical starting point of a knowledge system，and clarifying the concept of kinesiology is a crucial prerequisite for constructing China’s autonomous knowledge system.Using literature review，logical analysis and historical analysis，this study，from the perspective of conceptual history，examines the evolution of kinesiology concepts in both Western and Chinese contexts and explores their sinicization construction.The findings show that in the West，disciplinary terminology has evolved from Physical Education to Sport Science and then to Kinesiology，alongside a shift in research focus from physical education to competitive sport and further to physical activity and health，exhibiting an evolutionary trajectory characterized by educational，scientific，and comprehensive orientations.In China，commonly used disciplinary names have included Physical Education，Kinesiology，Sport Science and Discipline of Physical Education，with Sport Science and Kinesiology being most frequently adopted in contemporary usage.The evolution of conceptual connotations in China is characterized by scientization，institutionalization，and practical orientation.Building on traditional Chinese formulations，this study reconstructs the concept using the method of definition by genus and differentia.It proposes that kinesiology is the science that takes physical movement as its object of study，integrates methods from the natural sciences and the humanities and social sciences，and systematically investigates the regularities by which physical movement promotes human physical and mental development，social progress，and cultural formation.

The transformation in adapting to digitalization of public sports spaces in urban communities in China is a crucial approach to overcome the constraints of “incremental expansion” and achieve the goal of “quality improvement of existing stock” in the urban areas.This study uses literature review，field research and logical analysis to theoretically explore the transformation in adapting to the digitalization of public sports spaces in urban communities in China.It suggests that the key areas for the transformation are at four parts of the mechanism，data，operation and standards； There are practical constraints such as unclear managing rights and responsibilities and inefficient departmental collaboration，high data barriers and unclear data value，lack of professional operation and long-term feedback，and vague unified standards and insufficient dynamic evaluation.Accordingly，the relief strategies are proposed： clarifying the division of rights and responsibilities and building a collaborative mechanism； co-building and sharing platforms and deepening intelligent applications； introducing a professional team and establishing a feedback system； and developing unified standards and implementing dynamic supervision.

Youth “sports delivery” services，an emerging business model that integrates sports services with the digital platform economy，are built on convenience—a feature that has engendered profound structural paradoxes.Using the methods of literature review，logical analysis and field research，and drawing on a paradox-based theoretical lens to integrate multidisciplinary perspectives，this study systematically examines the underlying logic of the model’s emergence and identifies paradox of convenience： the conflict between efficiency first and safety vacuum，the tension between personalized customization and standardization missing，and the contradiction between consumer empowerment and regulatory disorder.To resolve these paradoxes，the study proposes the multi-stakeholder collaborative governance paths：First，it calls for establishing venue safety standards and certification mechanisms，strengthening mandatory coach qualification reviews and safety training，and introducing compulsory service safety liability insurance to set a “safety threshold” for efficiency.Second，it recommends developing basic service norms and effect evaluation frameworks，creating a data-driven coach certification system，and strongly promoting standardized electronic service agreements to achieve “standardized personalization”.Third，it emphasizes clarifying the platforms’ gatekeeping responsibilities，strengthening the industry associations’ self-regulation，and improving consumers’ rights protection and supervision channels to foster a new pattern of collaborative governance.

Football is a typical sport in terms of injury risk.As participants in campus football，adolescents are both potential creators and bearers of risk.Given that the injured parties in youth campus football injury cases are usually primary and secondary school students with limited civil capacity，and that the issue of guardians’ tort liability arises when minors with limited civil capacity cause harm to others，it is necessary to clarify the determination in such cases under the “assumption of risk” rule by drawing on current judicial practice.Through the analysis of 222 judicial documents from China Judgments Online，this study holds that the degree of violation of the “game rules” should serve as the benchmark for determining whether the actor acted with intent or gross negligence.At the same time，schools cannot be exempted from liability under the “assumption of risk” rule.Instead they should adopt an objective judgment standard to determine whether they have fulfilled their educational and management responsibilities，while fully considering the physical and mental characteristics of minors.Schools can promote socialized risk sharing by providing students with specilaized insurance for sports-related accidental injuries.

Consolidating the sense of community for the Chinese nation is a crucial contemporary proposition in advancing the cause of socialism with Chinese characteristics in the new era.It is also a fundamental task that school physical education must undertake.Using literature review and logical analysis，and drawing on cultural semiotics，this study constructs a theoretical framework comprising three dimensions—material，behavioral and spiritual—emphasizing the critical role of cultural symbols as the cognitive foundation，emotional bond，and carrier of value identity.This study identifies the psychological mechanism underlying the formation of the sense of community for the Chinese nation in terms of cognition，emotion and behavior，and further translates these into practical approaches characterized as “visible，affective and effective”.It suggests that school physical education should visibly highlight cultural symbols in teaching，extracurricular activities and sports competitions；create emotional resonance through affective experiences involving families，schools and communities；and establish a dynamic monitoring and evaluation system through effective mechanisms.This study expands the application perspective of semiotic theory in the field of school physical education and provides practical approaches for consolidating the sense of community for the Chinese nation through school physical education.

As a typical representative of new quality productive forces，low-altitude economy has become a new engine to activate the driving force of industrial development.By using the methods of literature review，case analysis and logical deduction，this paper explores the mechanisms and paths of transformation and upgrading of sports tourism industry empowered by low-altitude economy.It holds that the low-altitude economy empowers the production factors of sports tourism industry to transition to new qualitative forms such as intelligent equipment，digital technology and airspace resources with the cooperation of technical factors，policy factors and market factors，and presents the following mechanisms： innovating experience scenes to expand consumption dimensions； technology empowering operations to improve security； shaping brand symbols to activate flow economy； and breaking through space restrictions to reconstruct tourism forms.However，there are the following practical obstacles in practice： the opening of low-altitude airspace is sluggish，and the project expansion is constrained； the autonomy of core technology is not strong，and there are hidden dangers in operation safety； the brand value imprint is not deep，and the market potential is difficult to release； and infrastructure layout is insufficient， and application scenarios are lacking.Accordingly，the practical paths are put forward： promoting the innovation of airspace control to optimize the coordination of airspace resources； strengthening the breakthrough in core technology to smooth the transformation of innovation achievements； deepening brand value shaping to promote product symbol recognition； and improving the three-dimensional layout of infrastructure to consolidate the guarantee of tourism services.

Competitive sports events serve as a key engine for consolidating the foundation of building a sports power and driving high-quality development in sports. By the methods of literature review， expert interviews and logical analysis within a three-dimensional “structure-function-dynamics” framework， this study systematically examines the fundamental connotations， logical rationales and practical constraints of China’s competitive sports event system， thereby proposing optimization pathways. It concludes that the structural dimension of China’s competitive sports event system encompasses event tiers， project layout and institutional guarantee， serving as the core elements and intrinsic logic underlying the system’s operation； At the functional level， synergistic evolution through value integration， service upgrades and digital-intelligent innovation drives the event system toward a multi-value symbiosis； The dynamic mechanism leverages endogenous and exogenous forces to form a multi-faceted synergy， propelling the sustainable development of the event system. Currently， China’s competitive sports event system faces practical challenges such as uneven event distribution， irrational resource allocation， insufficient release of diverse values， lack of in-depth exploration in innovation paths， inadequate endogenous momentum， and excessive reliance on external sources. Accordingly， the following optimization pathways are proposed： refining the event structure to build a system characterized by “vertical integration and horizontal linkage”； expanding event functions to achieve comprehensive development of competitive excellence and social benefits； and stimulating event momentum by improving multi-faceted collaborative operational mechanisms.

The coupling coordination of digital economy and sports industry represents a significant manifestation of the integrated development of the internet and the real economy. Based on panel data from 22 provincial-level regions in China from 2018 to 2022， this study calculates the coupling coordination degree between digital economy and sports industry. The obstacle degree model is employed to identify the constraining degree of evaluation factors within the digital economy and the sports industry， while a panel regression model is used to examine its external influencing factors. The findings reveal a general upward trend in the coupling coordination with significant regional disparities existing across the eastern， central and western provinces. Within the digital economy system， the primary obstacles， ranked in descending order of severity， are digital innovation capability， digital industrialization， digital infrastructure and industrial digitalization. For the sports industry system， the main obstacles are sports employment， sports output， sports investment， sports enterprises and sports consumption in descending order. Regarding external influencing factors， the level of economic development demonstrates the most robust and consistent influence on the coupling coordination between digital economy and sports industry. Based on the above， this study proposes paths to enhance this coordination： strengthening regional division of labor to adapt digital economy development strategies to local conditions； addressing weaknesses in sports employment and sports industry to classify and improve safeguard mechanisms for essential production factors of sports industry； and reinforcing comprehensive planning to foster the coupling coordination between economic development， digital economy and sports industry.

This study examines the connotation，practical challenges，and implementation strategies of community sports health governance from the perspective of active health by employing literature review，policy text analysis，and inductive analysis.The analysis shows that current practice still faces several challenges，including a mismatch between resource allocation and demand，insufficient sustained participation among residents，incomplete multi-stakeholder collaboration mechanisms，limited data governance capacity，and insufficient long-term financial support.These challenges hinder the transformation of community sports from activity-based provision to broader health promotion.In response，the study proposes that community sports health governance should be oriented toward health outcomes.It should optimize the allocation of community sports resources，strengthen residents’ health literacy and capacity for sustained participation，develop multi-stakeholder collaboration mechanisms involving sports and health departments，communities，and social organizations，improve data governance rules and platform coordination mechanisms，and optimize the investment structure while strengthening performance evaluation.These strategies can help develop a community-based，sports-enabled，and digitally supported approach to community sports health governance，offering a reference for promoting health for all and advancing health equity.

The new whole nation system is the core institutional support for China’s competitive sports to break through development bottlenecks and move towards high-quality development in the new era. Its deep integration with competitive sports has distinct historical inevitability and current urgency. By the methods of literature review and logical analysis， this paper systematically clarifies the historical and contemporary logic of the emergence of the new whole nation system， comprehensively analyzes the political and economic connotations of the high-quality development of competitive sports under the new national system， and deeply explores its inevitable requirements. It holds that the high-quality development of competitive sports is the core support for serving the overall national development strategy， a breakthrough strategy to adapt to the global sports governance reform and the technological revolution， an important way to enhance China’s sports international discourse power and influence， an inevitable logic for promoting the deep integration of mass sports and competitive sports， and a powerful engine for accelerating the cultivation of new growth drivers for the sports industry. From the two dimensions of cultivating new quality productive forces and reshaping new type of production relations， it proposes practical paths with both Chinese characteristics and contemporary features， aiming to provide theoretical references and practical guidance for the institutional innovation and path transformation of China's competitive sports in the new era.

Against the backdrop of deepening education reform，promoting the ecological construction of “great ideological and political education in sports” based on the “all-round education for all” strategic framework is of crucial significance for fully leveraging the unique educational function of sports and responding to the demand for high-quality talent cultivation in the new era.Using the methods of literature review and logical analysis，this paper elaborates on the internal logic，core values，and practical challenges of the ecological construction of “great ideological and political education in sports”，and proposes practical paths.It suggests that its core values mainly include building the foundation for “value guidance” in education to implement the fundamental task of cultivating virtue and nurturing people；reshaping the “Five Education Integration” education chain to innovate the paradigm of quality education cultivation；and connecting the collaborative education bond of “family，school and community” to strengthen the cultivation of social responsibility awareness.However，the ecological construction of “great ideological and political education in sports” still faces practical difficulties such as the lack of collaborative mechanisms，obstacles to the integration of ideological and political elements，broken adaptation of the education system，and lagging integration functions in the field.Accordingly，practical paths are proposed： to improve the mechanism of shared responsibility for education so as to gather diverse collaborative efforts for education；to design ideological and political education goals at different levels so as to achieve precise alignment between disciplinary characteristics and cognitive laws；to connect the entire cycle of education chain so as to establish a system that links ability advancement and value internalization；and to reconstruct the educational functions of spatial field so as to promote the organic integration of explicit training and implicit influence.

The analysis of the construction process evolution of China’ s independent knowledge system of sports science is the ideological basis of the construction of Chinese-style sports science. From the logical starting point of “human-sport” interaction， this study systematically traces the ideological evolution of the construction of China’s sports science. It suggests that in the initial phase of “Western Sports Science in China”， the construction started from the deconstruction of the community of sports and traditional society， which manifests the confusion of ontology and cognitive theory of academic system， axiological lag of academic system， and autonomy crisis of discourse system； In the phase of “sinicized western sports science”， the construction focused on the reconstruction of the community of sports and modern society， which realizes the rational reorganization of academic system， the realignment of value anchoring of academic system， and the autonomy establishment of discourse system； In the phase of “Chinese-style sports science”， the construction sets the building of a community with a shared future for mankind as idea of development， which realizes the cognitive breakthrough of academic system， value leading of academic system， and practical promotion of discourse system.

There is an urgent need to address the ongoing decline in the physical health of college students in China.Health governance provides a systematic guidance framework to solve the problem.Building on a deep analysis of the connotation，value and theoretical foundation of university health governance，this study summarizes a general course of action for university health governance by examining international and domestic “healthy campus” cases like The Healthy Campus Framework published by American College Health Association.Through literature analysis and case study，it has been found that college students’ physical health levels generally begin to decline significantly from their junior year in China，also showing that the physical health condition of college students is the result of comprehensive influence of multiple factors including their personal behaviors and the environment.Building on these influencing factors，the study further analyzes the stakeholders’ responsibilities to establish a cognitive framework for university health governance promoting college students’ physical health.Guided by this framework，this study proposes the practice modes，suggesting that universities should aim at promoting the health of college students by undertaking multi-level governance planning led by policy-making bodies，establishing a health governance framework while forming a stakeholder consortium centered around the "Health Committee" within universities，building a governance network for sharing physical health data from college students，and creating an evaluation system that allows various stakeholders to provide feedback and make corrections，which are designed to achieve collaborative health governance in universities through the active participation of multiple stakeholders.

The integrated governance of community sports， medical care and elderly care is not only an enduring research topic concerning an aging society in academic circles， but also a practical focus that needs urgent attention in grassroots health governance. Adopting research methods including literature review， field investigation and expert interviews， this study examines the adaptive logic between holistic governance theory and the integration of community sports， medical care and elderly care， and proposes holistic governance pathways to address the fragmentation problems existing in such integration. The study finds that the fragmented dilemmas of community sports-medical-elderly care integration stems from several key issues: divergent multi-dimensional value objectives caused by interest differences among multiple stakeholders， difficulties in overall policy coordination and integration due to fragmented top-level systems， functional barriers between departments resulting from the segmented management of organizational institutions， and non-standardized governance processes induced by the lack of holistic governance tools. In response to the above dilemmas， this study proposes targeted holistic governance paths: reshaping the goal and value system of integrated governance to meet the health needs of the elderly； optimizing the top-level institutional overall planning and formulating sustainable development plans for community integrated governance； strengthening cross-departmental collaboration between sports authorities and relevant sectors to promote the integrated development of public services； and empowering governance with comprehensive tools to realize refined and digital intelligent governance. This research thus aims to provide theoretical support and practical guidance for the high-quality development of community sports-medical-elderly care integration.

Localized education of rural schools sports in ethnic regions is an effective way to address the tension between educational modernization and localization in the context of building education power and sports power in the new era，and to achieve high-quality development of rural schools sports in ethnic regions.Through the methods of literature review and logical analysis，this study explores the appearance context，forms and paths of localized education of rural schools sports in ethnic regions.It suggests that rural schools sports in ethnic regions is facing practical challenges such as “deterritorialization” and “cultural virtualization”.Localized education advocates for deep interaction between schools sports and local communities，as well as the creative transformation and utilization of indigenous resources，aiming to drive fundamental reforms in the forms of rural schools sports of ethnic regions.The study presents the emergence form of localized education in rural schools sports in ethnic minority areas，which involves the reconstruction of cultural confidence，the integration of cultural soil and the cultivation of cultural heritage.It proposes emergence paths such as stimulating the subject consciousness，building a symbiotic system of home，school and community，and developing local sports courses.

CHE Xiangchen's physical education thoughts served as the theoretical forerunner for the reform and innovation of physical education practice， and his physical education practice of personal implementation was the benchmark for the transformation of his thoughts， leaving behind a valuable legacy for the development of physical education in China. By the methods such as historical analysis and historical data verification， this paper systematically reviews the historical evidence of CHE Xiangchen’s physical education practice： The foundation was laid by the “saving the country and strengthening the race” concept of popular education based on the “educating people through sports” model； The practice was shaped by militarized sports education centered around the “developing a sound personality and physique” principle； The students’ comprehensive qualities were cultivated making “integrating labor education into physical education” as the core； And the radiation of an educational network was applied based on the collaborative education of the “little teacher system”. On this basis， by grounding in the value foundation of his physical education practice， this paper reflects on the contemporary predicaments of physical education practice： the deviation of value orientation from the goal of all-round education， the blurred boundaries of responsibilities among families， schools and communities， the weak foundation of family sports， and the fragmented social support system. Accordingly， with the aim of providing references and inspirations for contemporary physical education practice， it proposes the paths of paradigm reshaping： promoting the rational return of the value of life-oriented physical education， constructing an integrated network of educational ecosystem of functional complementation， realizing the effective connection of the transmission path of family sports capital， and optimizing the guarantee mechanism for the integration and sharing of social resources.

This study selected a total of 99 matches from seven teams including Italy，Brazil，Japan，the United States，Poland，Türkiye and China in the 2024 Volleyball Women’s Nations League as research objects.Using literature review，video review and technical statistics，this study systematically compared the official FIVB data.It then conducted an in-depth evaluation of the gap between the offensive and defensive competitive levels of the Chinese women’s volleyball team and world-class teams，as well as the causes of the gap，aiming to provide scientific training references and competitive level improvement pathways for the team’s preparation for the 2028 Los Angeles Olympics.The results show that the Chinese women’s volleyball team leads in height （190.67 cm），spike height （318.50 cm） and block height （306.50 cm），but fails to effectively convert these advantages into victories in key matches.The Chinese women’s volleyball team ranks first in spike scoring rate （45.77%） and setter arrival rate （21.56%） but fifth in reception arrival rate （23.30%） and block scoring rate （17.79%），amd the technical conversion efficiency is significantly lower than that of world-class teams such as Italy，Poland，and Brazil.There is a structural imbalance in the technical stability of the Chinese team: while it has the lowest service error rate （8.59%），it has the highest reception error rate （8.43%），reflecting significant fluctuations in competitive level under pressure.Especially in several matches，weaknesses in defensive resilience，key point execution and lineup stability were exposed.Accordingly，the Chinese women’s volleyball team needs to establish a dual-driven system of “technical refinement + systematic support”.（1） Technical level: refine spike route differentiation and coordinate block anticipation，develop a balanced tactic system for both attack and defense，strengthen pressure training for reception，and enhance the artistic quality of setters’ organization under adversity； （2） Support level: establish an injury monitoring and rehabilitation system，optimize the integration and inheritance mechanism between new and veteran players，strengthen physical and psychological conditioning，implement match-specific refined strategies，thereby systematically improving overall competitiveness and match resilience.

Objective: To investigate the effects of a 12-week comprehensive exercise intervention on physical fitness and executive function in primary and secondary school students and the relationship between them，and to provide an effective program for physical-cognitive integration. Methods: A 12-week comprehensive exercise program was developed for primary and secondary school students respectively based on their physical-cognitive characteristics，and implemented with 544 students. Results: The intervention significantly improved physical fitness and executive function.Primary students improved in speed，explosive power，cardiorespiratory endurance，agility，coordination，inhibition，updating，and shifting.Middle school students improved in speed，explosive power，agility，coordination，inhibition，updating，shifting，as well as flexibility and strength endurance.Additionally，male students showed improvement in cardiorespiratory endurance.Updating gains in primary students were associated with agility and cardiorespiratory endurance，with agility showing a stronger association；shifting gains in middle school students were associated with agility. Conclusions and suggestions:: The developed program effectively promotes coordinated physical and cognitive development，with agility as a core target.Future practice should employ agility via grade-level differentiated tasks and cognitively engaging complex situations under moderate-to-high intensity.

The practice of large-scale sports events driving the Healthy China initiative exhibits fragmented and short-term characteristics.How to achieve the long-term transformation of the health benefits of large-scale sports events through systematic governance has become a critical issue requiring urgent resolution.Employing methods such as literature review，logical analysis and case studies，this research introduces catalyst theory and constructs a dynamic analytical model of “catalyst activation-effect diffusion-ecological solidification”.It elucidates the driving process whereby large-scale sports events initiate catalyst activation through health-oriented strategic anchoring and element implantation，subsequently triggering chain reactions that promote the diffusion of catalyst effects，and ultimately achieve the ecological solidification of health benefits through normalized construction.Currently，this driving process faces practical obstacles including deviations in goal orientation，fragmentation in the execution process，and difficulties in sustaining outcomes.Accordingly，the systematic governance paths are proposed：centered on the return to goal orientation，reshaping of the execution process and optimization of outcome sustainability，and supported by enhanced efficacy assurance.

Rural sports is an important part of the comprehensive revitalization of rural areas，and the comprehensive revitalization of rural sports has a unique contemporary value.At present，rural sports still faces many practical difficulties:insufficient development of industrial factors，weak supply of sports professionals，lagging awareness of sports culture，ecological imbalance，and ineffectiveness of organizational system.The development of rural sports must rely on the foundation of social development，establish the concept of comprehensive revitalization and development，and form a new pattern:integrating rural resources and innovative business forms to strengthen the sports industry； cultivating rural sentiment and combining education with recruitment to promote talent revitalization； continuing the rural cultural lineage and reshaping values to boost sports culture； building on ecological foundations and green empowerment to lead sports ecology； and adhering to the guidance of Party building and villagers’ autonomy to achieve organizational revitalization.The comprehensive revitalization of rural sports must be based on rural realities，the paper proposed the implementation paths with rural characteristics:making multi-dimensional efforts to stimulate new momentum in the rural sports industry； accurately cultivating rural sports professionals； reshaping the cultural value of excellent traditional rural sports； building a coordinated development model of the rural sports ecology； and optimizing a multi-stakeholder co-governance structure of rural sports.The above paths will enable the power of sports to contribute to the all-round revitalization of rural areas in the new era.

The de facto power of International Sports Federations refers to the regulatory power accepted in global sports practice without explicit legal authorization. By the methods of literature review and case analysis， this paper systematically examines the origins， manifestations， and legal nature of this power. It shows that the power is rooted in the monopoly of International Sports Federations and the pyramid structure of international sports governance； the basic forms of de facto power can be summarized as quasi-legislative power， quasi-administrative power and quasi-judicial power； Legally， de facto power has the external effect of social public power and the internal risk of alienated power. Jurisprudential reflection reveals that the de facto power of International Sports Federations may deviate from the basic spirit of social contract theory in operation， and it may infringe many human rights of athletes. To effectively regulate this power within a legal framework， two suggestions are proposed： first， establishing a permanent representative body for athletes， promoting collective bargaining， and introducing the principle of corporate governance to make up for the democratic deficiencies in the governance structure； second， clarifying and strengthening the primary regulatory and remedy responsibilities of the countries where the headquarters of International Sports Federations are located， expanding the judicial remedy channels for athletes to claim rights from multiple subjects， and establishing the judicial intervention principles and review standards of respecting autonomy， necessary involvement， and substantive review to safeguard human rights.

Empowering the promotion of adolescent exercise health through digital technology is fundamental to enhancing their physique.Utilizing the methods of literature review and logical analysis，this paper systematically explores the logical evolution of the promotion of adolescent health promotion in China.Based on the connotative deconstruction of the promotion under the digital background，it establishes a logical framework characterized by goal guidance，demand traction，modality transformation，and quality-efficiency enhancement.It reveals several practical challenges： weak support of digital elements and inadequate guarantee of service resources；lagging individual cognitive transformation and weak digital health concepts；low organizational empowerment and a lack of external environmental vitality；and improper hardware configuration alongside an imbalanced functional structure of supporting systems.Accordingly，the paper proposes countermeasures： consolidating the digital foundation and optimizing service supply mechanisms；improving adolescents' digital health literacy and reshaping the cognition of digital health concepts；deepening multi-organizational synergetic empowerment and stimulating digital ecosystem vitality；and promoting the integrated configuration of software and hardware and refining the digital support service system.

The idea of a community with a shared future for mankind provides positive guidance and action guidelines for the sports culture in today's world to move towards common prosperity.By the methods of literature review，comparative analysis and logical reasoning，the study systematically analyzes the examination of characteristics，internal logic and future progress of the differentiated development of Chinese and Western sports cultures from the perspective of a community with a shared future for mankind.It concludes that the different geographical environments，economic types and social forms at the beginning of the Chinese and Western civilizations have created the differences in the traits of the sports cultures，such as stability and adventure，harmony and competition，and community and ego； and that the concepts of common interests，global governance and sustainable development embedded in the idea of a community with a shared future for mankind have built the theoretical cornerstones，improved the safeguarding mechanism and offered directional guidance to the development of the differentiation of the sports culture between China and the West； In the future，under the guidance of the idea of a community with a shared future for mankind，it is necessary to insist on respecting the compatibility of Chinese and Western sports cultures as the premise，deepening the exchange and mutual understanding of Chinese and Western sports cultures as the support，and carrying forward the flashpoints of Chinese and Western sports cultures as the means，so as to realize the coordinated prosperity of the differentiated development of Chinese and Western sports cultures.

From the macroscopic perspective of inheriting the context of China’s outstanding traditional culture， the protection and inheritance of ice and snow sports culture serve as essential support for the continuation， promotion and innovative development of traditional sports culture. Based on the perspective of cultural memory， this study adopts the methods of literature review， field investigation and in-depth interview to systematically explore the protection and inheritance of China’s ice and snow sports culture from the perspective of cultural memory theory. The research holds that cultural memory theory focuses on the internal generative logic of national identity and cultural identity， which is highly consistent with the practice of protecting and inheriting of ice and snow sports culture， and provides a new research perspective for building a shared memory of ice and snow sports culture. At present， the protection and inheritance of China’s ice and snow sports culture are confronted with practical dilemmas such as the fading recognizability of symbolic systems， the intergenerational rupture of emotional connection， and the functional weakening of value chains. Accordingly， this paper proposes to follow the main thread of ice and snow sports cultural memory， achieve the collaborative governance by multiple subjects， and realize the protection， inheritance and innovation of ice and snow sports culture by reconstructing the symbolic memory， continuing the emotional memory， and activating the value memory.

Sports exhibitions are a crucial approach to promoting the concrete spirit，emotional connection and cultural promotion of sports events.Through interviews with 25 sports exhibition professionals and using the qualitative research method of the grounded theory，this study conducts open，axial and selective coding to construct a three-dimensional theoretical model of the scenario-based presentation of sports exhibitions.It holds that the scenario-based presentation of sports exhibitions encompasses three dimensional scenarios of competition，audio-video and ritual，highlighting the functions of concrete spirit，emotional connection and cultural promotion；It has value connotations such as perceiving the charm of competition，enhancing sponsorship returns，empowering the images of cities，spreading cultural heritage and embodying national identity.Therefore，the following development paths are proposed:creating interactive sensory experiences in stadiums to create virtual spaces for sports exhibitions；adapting to the multi-industry development trend to increase the consumption stickiness of sports events；projecting distinct urban identification to achieve interconnection and resonance in urban development；artistically representing cultural codes to extend the appeal of the ritual scenarios；and enhancing empathetic communication to stimulate emotions and get identifications.

With the continuous advancement of smart community construction and the improvement of public fitness facilities，the digital transformation of sports infrastructure in urban communities has achieved certain results. However，the potential of digital technology in optimizing residents' sports experience and enhancing sports participation has yet to be fully realized. Therefore，this research，based on the analysis of the connotation of sports infrastructure in urban communities，focuses on exploring how the four aspects of funding，technology，institutions and talent can work together to promote the digital transformation and sustainable development of sports infrastructure in urban communities. Through field research in communities in Beijing，Shanghai，Hangzhou，Chengdu and other cities，it is found that there are realistic obstacles in the renovation process，including insufficient funding，outdated technology，lack of clear responsibility and talent shortages. Accordingly，strategies have been proposed，such as expanding diversified funding channels，integrating hardware into core technical systems，clarifying property rights and responsibility boundaries，and promoting the cultivation of multidisciplinary talents. These strategies aim to shift the traditional sports infrastructure in urban communities from quantitative expansion to qualitative improvement，thus promoting the high-quality development of urban community sports.

The space governance of rural sports is not only a crucial means to advance the modernization of national sports governance，but also a necessary measure to promote the construction of livable，business-friendly，harmonious and beautiful countryside.This study uses case analysis，semi-structured interviews and logical analysis to explore the connotations，action mechanisms，and practical paths through which rural sports space governance promotes the construction of harmonious and beautiful countryside.It finds that the action mechanisms by which rural sports space governance promotes harmonious and beautiful rural construction include ecological integration and functional enhancement，business innovation and consumption activation，and cultural revitalization and identity shaping，which help to consolidate a livable ecological foundation，stimulate development momentum，and foster a core spirit of harmony and beauty.Based on the experience of Zhejiang Province，it proposes practical paths： optimizing the ecological space base of rural sports to promote livability； enhancing the value of rural sports production spaces to promote business-friendly environments； and cultivating the culture of rural sports living spaces to promote harmony and beauty，thereby providing strong supports for comprehensive rural revitalization.

As artificial intelligence （AI） rapidly penetrates public service delivery systems，it is becoming an important driver of China’s government-led and socially coordinated national fitness organization network construction.Drawing on literature review and logical analysis and focusing on the key parts in it，this paper systematically elucidates the empowering pathways through which AI supports network development： data integration，standard modeling，computing power scheduling and organizational restructuring.It further highlights several constraints that may emerge during intelligent transformation，including departmental fragmentation and privacy constraints that can weaken collaborative efficiency，standardization bias embedded in general-purpose generative models that may produce mismatches between technical schemes and place-specific needs，spatial concentration of computing resources that can widen urban-rural disparities in the accessibility of public sports services，and the expansion of algorithmic instrumental rationality that may induce the alienation of human-machine collaboration.Accordingly，the paper proposes the practical dimensions： enhancing the efficiency of data collaborative governance through “sandbox regulation plus flexible regulation”； improving the contextualization and equity of standard paradigms through “government data plus human observation”； reducing the urban-rural accessibility gap and the digital divide through “edge federation plus computing power sinking”； and advancing co-construction，co-governance and human-machine symbiosis through “distributed participation plus social embedding”.These insights provide theoretical support and policy implications for the high-quality development of China’s national fitness business.

Promoting the supply and demand matching in outdoor sports consumption scenarios in China is of great significance for expanding domestic demand.This study employs the methods of literature review and logical analysis to explore the theoretical logic，practical constraints and promotion strategies of the supply and demand matching of outdoor sports consumption scenarios under the strategy of expanding domestic demand.It suggests that under the strategy of expanding domestic demand，the logical representation is reflected in the following aspects： the guidance of policies and systems promotes the rational layout of venues and facilities； the application of digital and intelligent technologies drives the innovative expansion of events and activities； the integration of natural environments promotes the diversified supply of sports fields； and the improvement of regulatory standards realizes the integration and coordination of equipment resources.The practical constraints are reflected in the following aspects： The efficiency of policy and system implementation is low，which weakens the initiative of integrating outdoor venues and facilities； High-end value-added service technologies need to be strengthened，which restricts the multi-level development of outdoor sports events and activities； The coordination and symbiosis of natural environmental resources is poor，which hinders the diverse supply of outdoor sports fields； The regulatory standards are misplaced，which weakens the efficiency of resource allocation for outdoor equipment.Accordingly，the following promotion strategies are proposed： promoting the planning and deployment of outdoor venue facilities，releasing the technological innovation momentum of enterprises，strengthening the supply of diverse natural fields in accordance with local conditions，and improving the access standards for outdoor sports equipment.

Against the backdrop of the continued release of post-Winter Olympics dividends，digital transformation is leading the ice and snow economy into a new stage of high-quality development.Drawing on path dependence theory，this study systematically examines the evolutionary logic，practical obstacles，and resolution strategies of digital transformation in China’s ice and snow economy under conditions of path dependence.This study argues that technological lock-in driven by increasing returns，structural rigidity driven by institutional inertia，pattern consolidation driven by spatial lock-in，and capability ossification driven by mental models have collectively given rise to technological，organizational，market，and cognitive path dependencies.Under these path dependencies，the digitalization of the ice and snow economy continues to face practical obstacles，including the lock-in effects of legacy technological systems，inertial constraints of traditional management models，institutional inertia of the traditional industrial ecosystem，and conceptual barriers to digital transformation.On this basis，the study proposes a set of resolution strategies： building an autonomous and controllable digital technology system，advancing digital reform of management systems，breaking down institutional barriers within the traditional industrial ecosystem，and cultivating an innovation culture conducive to digital transformation—with the aim of providing theoretical guidance and policy insights for advancing the digitalization of the ice and snow economy.

Enhancing the resilience of China’s ice and snow economy industrial chain is not only an inevitable choice to stimulate the vitality of the ice and snow economy，but also an inherent requirement for forging new paths for its development.By using literature review and logical analysis，this study examines the resilience of China’s ice and snow economy industrial chain from the perspective of stimulating the vitality of its economy.The study suggests that the logic underlying the enhancement of resilience in China’s ice and snow economy industrial chain lies in that it represents an inevitable choice in transitioning from the development of “cold resources” to the construction of a “hot economy” system；it is an inherent requirement for complex systems to address multiple uncertain risks；and it is an urgent need to align with national strategies and the actual development of the industrial chain.However，efforts to enhance China’s ice and snow economy industrial chain resilience still face practical obstacles，including weak industrial foundations and insufficient resistance of core links；rigid market demand response and a lack of dynamic system adaptability；outdated safety guarantee system and weak post-incident recovery and learning capacity；inefficient transformation of innovation elements and restricted access to high-end value chain；and the absence of cross-regional collaborative governance，which hinders the formation of structural resilience.Based on this，this study proposes practical approaches to enhancing the resilience of China’s ice and snow economy industrial chain： ensuring the autonomy and controllability of key links；emphasizing demand perception and flexible supply adaptation；improving the safety emergency and resilience recovery system；driving the deep integration of the innovation with the industrial chain；and building cross-regional collaboration and communities of interest.

The modernization of rural public sports service governance is an inevitable requirement for the construction of basic public service system and the implementation of Rural Revitalization Strategy.Using the methods of literature review，case analysis and network survey，this study analyzes the logic and dilemmas of rural public sports service governance from the perspective of national basic public service standards，and puts forward countermeasures，aiming to provide references for the construction of a higher level of rural public sports service system.It shows that the national basic public service standards promote the transformation of rural public sports service governance from the aspects of concept compliance，supply standard，practice dimension，technology construction and system guarantee.In order to resolve the governance dilemmas such as the hysteretic governance concept of diversified development，service supply deviating from standards and unclear practice dimensions，lack of digital technology construction，and insufficient institutional guarantee for collaborative governance，the solutions should be taken to strengthen concept compliance so as to shape the diversified development pattern of rural public sports services； to clarify the standards and dimensions so as to improve the fine management level of rural public sports services； to deepen digital construction so as to unblock the channels for in-depth promotion of rural public sports services； and to improve institutional guarantee so as to strengthen the efficiency of collaborative governance of rural public sports services.
