(2) VBT is suitable for monitoring explosive force performance related to Ballistic training, promoting the improvement of muscle power output ability and metabolic adaptability. (3) VBT is an effective way to improve the rigidity of the muscle-tendon complex under rapid force, improve centripetal/centrifugal imbalance and muscle coordination, promote muscle fiber type conversion and nerve driven dynamic muscle strength enhancement. (4) The application of VBT combined with digital monitoring equipment can accurately and objectively set load intensity, provide real-time feedback on training rhythm and completion quality, and effectively predict Dynamic Strength Index (DSI) and integrate training elements. (5) VBT can effectively activate the neuromuscular system while monitoring fatigue based on velocity loss, improve sufficiency and repeatability of training, and achieve simultaneous training of muscle strength/explosive power and aerobic power. Conclusion: VBT helps to improve the refinement, personalization, and accuracy level of training load monitoring and training program control, and has good applicability in promoting the adaptability of neuromuscular function, as well as in functional training such as Ballistic training for development of rapid strength and explosive power.

Using literature analysis, logical analysis, historical analysis, and comparative research methods under the Multiple-Streams theoretical framework, this study systematically examines the evolution of adolescents’ sports health promotion policies in China since the founding of the People's Republic of China, and divides the evolution into five stages: exploration period of New China founding (1949-1966), turbulence period of 'Cultural Revolution' (1966-1977), development period of reform and opening-up (1978-1998), transformation period of new century (1999-2011), and advancement period of New Era (2012-present). The evolutionary characteristics are identified: transitioning from focusing on national defense to student fitness enhancement, and subsequently from physical fitness to comprehensive sports health. And the dynamic mechanisms are demonstrated: problem stream providing endogenous motivation, policy stream providing intellectual impetus, political stream providing fundamental driving force, the strategic integration of which constitutes the driving mechanism for policy evolution. Building on the previous analysis,optimizing strategies are proposed, namely enhancing problem identification addressing practical needs, expanding policy advocacy for decision-making optimization, strengthening political guidance for institutional refinement and promoting the convergence of three sources for driving policy linkage.

New quality productivity is an important driving force for the high-quality development of Chinese path to modernization, showing strong theoretical applicability and guidance. Seeking ways to develop in response to the shortcomings and problems faced by the current marathon event, mainly using literature review, the authors in this study take the empowerment of new quality productivity in marathon events as the research object, exploring its theoretical logic, practical difficulties, and improvement paths. It is believed that the value of new quality productivity in empowering marathon events lies in promoting supply side structural reform, leveraging the effect of supplementing and strengthening chains, strengthening data empowerment, and improving event quality and services; In response to the persistent problems of marathon events: imbalance, insufficiency, incompleteness, and lack of coordination in the race; lack of innovation capability, making it difficult to form unique event IPs; imperfect organization and operation mechanism of the competition; and lack of sound industry chain centered around sports events., the authors put forward several suggestions from macroscopic, medium and microscopic levels. Macroscopic level: assess the situation, clarify the direction, and strengthen guarantees; Medium level: strengthen technological empowerment, shape distinctive event IPs, and enhance security standard; Microscopic level: correct attitude towards competition, enhance knowledge of sports health, and promote the spirit of sports.

Against the backdrop of the convergence of population aging and the digital technology revolution, digital intelligence empowerment provides new technical support and methodological innovation for the active health management of the elderly. However, the digital and intelligent active health management of the elderly is still in the stage of exploration and development in China, and its theoretical connotation and practical path are still constantly evolving and improving. This study employs research methods such as literature review and logical analysis to systematically sort out the basic connotation of digital intelligence empowering the active health of the elderly. Based on the traditional TOE theoretical framework, “Human” factors are introduced to form the TOE-H combination framework, highlighting the subjectivity and heterogeneity characteristics of the elderly group. Based on the four-dimensional aspects of technology, organization, environment and population, this paper systematically analyzes the practical predicaments and solutions faced by the practice of active health management for the elderly empowered by digital intelligence. Research suggests that the fundamental connotation of intelligent empowerment for the active health of the elderly lies in the deep integration of digital intelligence technology and the active health of the elderly, building a data-driven and intelligent decision-making personalized health management model, promoting the transformation of the elderly from passive medical treatment to active prevention, and achieving an overall optimization of their physiological, psychological and social functions. At present, the application of digital and intelligent technologies faces practical predicaments such as insufficient elderly-friendliness, lagging digital transformation of the elderly care service system, imbalance in the supply of the digital inclusive health service market, and a prominent digital divide among the elderly. Based on this, it is suggested to further promote the adaptation of digital and intelligent services and applications for the elderly, drive the digital transformation of the elderly health service system, improve policy guarantees and market ecosystems, strengthen social support and cognitive guidance, etc., with the aim of providing theoretical references and practical guidance for building a digital and intelligent elderly proactive health management system with Chinese characteristics.

To build a group of internationally competitive independent sports event brands, which can effectively connect the sports industry with urban elements, promote the integration of sports event brands into urban governance and sustainable development practices. The relationship between sports events and urban governance quality is based on a symbiotic relationship characterized by multi-party collaboration, multi-mechanism linkage, continuous mutual development, and shared development environment. However, there are some practical obstacles in the dimensions of symbiotic units, symbiotic interfaces, symbiotic models, and symbiotic environments, which significantly hinder the realization of the achievements in sports event brand building and their empowering effects. This article, combining symbiosis theory with the existing practical problems, analyzes the collaborative path between the sports event-related industry and the refined governance of the city, providing valuable exploration for leveraging sports events to address urban governance and development issues.

The National Games are an important part of my country's national system of competitive sports and are the highest-standard and largest comprehensive sports event in China. At present, the National Games are in a state of outstanding competitive sports and lagging economic functions. The reason is that the National Games market development is regarded as a short-term and independent project, resulting in temporary organizational structure, broken operation cycles, blurred rights and responsibilities mechanisms, and short-term development goals. Based on the perspective of "National Games economy", this article proposes that the market development of the National Games should carry multiple missions of sports industry upgrading, building a sports power and regional coordinated development. It is urgent to establish a cross-cycle national Games brand asset management as the core equity development paradigm. Based on the experience of Olympic marketing, we will build an equity-based market development system with resource grading, subject division of labor and profit distribution as the pillars, and propose a promotion path of brand shaping, legal system improvement, organizational permanent establishment and inter-government coordination, in order to provide theoretical reference and practical guidance for the market development and reform of the National Games.

The significant institutional shift in the governance of sports systems from a “competitive sports - centric” model to the “Qunjing Synergy” paradigm (the coordinated development of mass sports and competitive sports) is marked by the inclusion of mass sports events into the official competition framework of the 13^th National Games of the People's Republic of China. this transformation not only reflects the deepening of the national fitness strategy under the context of a sports powerhouse but also underscores the institutional innovation demands for reconstructing sports publicness. Grounded in the theoretical framework of Qunjing Synergy, this study employs institutional analysis and policy document review methodologies, combining critical policy nodes and practical cases to elucidate the synergistic driving mechanisms of four institutional logics: political integration, cultural identity, resource coordination, and social participation. It further examines structural tensions in practice domains, including conflicts in value objectives, misaligned governance structures, exclusionary rule systems, and deficits in participation motivation. Findings reveal that current mass sports events face formalistic institutional embedding dilemmas, with collaborative advancement mechanisms hindered by policy implementation disengagement, rule system misalignment, and weakened stakeholder coordination. Based on these insights, the study proposes an adaptive governance framework of “institutional integration - governance innovation-resource feedback-culture fusion” to provide theoretical support for optimizing the sports governance system in the new era.

Based on the background of building China into a sports power, this paper systematically combs the academic evolution and practical challenges of the concept of sports consumption, and reveals the logical dilemmas of the traditional "narrow-broad" binary division framework in narrowing, generalization and the definition of public good attributes. By analyzing the characteristics of sports consumption such as high-level needs, diversified forms, and public - private mixed nature, and combining the trend of integration of emerging formats and technology, this paper proposes a concept reconstruction framework with the core constraint condition that the whole process of "motivation - behavior - utility" conforms to the sports spirit. The framework emphasizes that sports consumption needs to meet the three-level standards of motivation (sports participation orientation), behavior (sports practice transformation) and utility (sports value realization), and verifies its effectiveness in excluding non - sports motivation consumption and defining public good payment disputes through cases. The study provides an interdisciplinary integration perspective for the theoretical innovation and practical development of sports consumption in the new era, and helps to achieve the goal of high - quality development of the sports industry.

Hosting major sporting events has become a significant force in driving regional economic and social development as well as cultural exchange. The Guangdong-Hong Kong-Macao Greater Bay Area's hosting of the 15^th National Games will facilitate the coordinated development of regional sports initiatives and accelerate the construction of the Sports Bay Area. This study employs literature review and field research to explore the intrinsic value and obstacles of the 15^th National Games in empowering the development of the Guangdong-Hong Kong-Macao Sports Bay Area, while identifying optimization pathways. The study concludes that the 15^th National Games demonstrates unique value in: - Promoting the renovation of sports venues to empower the development of a smart sports bay area; - Catalyzing urban development planning to empower the development of a modern sports bay area; - Boosting industrial synergy to empower the development of an industrial sports bay area; - Deepening regional cooperation and exchanges to empower the development of a cultural sports bay area. However, obstacles persist in this empowerment process, including: insufficient influence of major sporting events and underdeveloped sports markets; significant institutional differences between Hong Kong/Macao and the mainland, leading to regional development imbalances; inadequate sports-related laws and regulations creating barriers to event participation; and insufficient coordination in sports cultural exchanges, requiring further advancement of deep integration. Looking ahead, the Greater Bay Area must draw on the experiences of the world's three major bay areas to fully develop the “Three Regions, Three Centers” framework. It should leverage regional connectivity advantages to advance “hard connectivity” in sports infrastructure; break down barriers and unify standards to implement “soft integration” of sports regulations; and deepen exchanges aligned with contemporary trends to foster “heartfelt integration” of sports culture.

The 15^th National Games, jointly hosted for the first time across Guangdong, Hong Kong, and Macao, presents unique challenges for cross-border data flow governance under the framework of "one country, two systems, and three jurisdictions." Through policy text analysis, literature review, and empirical case studies, this research constructs a three-dimensional governance model encompassing "Sovereignty Layering-Technological Empowerment-rule Coordination." The findings indicate that a four-tier data classification system (Core Data, General Data, Derived Data, Public Data), based on data sensitivity and sovereignty relevance, enables differentiated governance. A three-tiered governance gradient comprising Central oversight, Regional Collaboration, and Market-Driven value Conversion effectively balances data security and flow efficiency. Furthermore, technologies such as blockchain, federated learning, and secure computation facilitate secure data circulation under the principle of "usable but invisible data." This research provides a systematic solution for sports data governance within the Guangdong-Hong Kong-Macao Greater Bay Area and offers an innovative paradigm for global cross-jurisdictional data governance practices.

Sports facilities serve as a crucial lever for promoting the high-quality development of sports, addressing shortcomings in sports infrastructure, understanding its current status and distribution, and strategically planning future layouts. They represent a vital pathway towards constructing a modernized sports powerhouse in China. Based on the perspective of spatial justice, utilizes multi-source data and GIS spatial analysis methods to analyze the spatial characteristics of sports facilities in Guangzhou. It evaluates their accessibility and equity from both grid and street scales, and provides suggestions for rational layout and optimization. The research reveals that: 1) Guangzhou's sports facilities exhibit significant clustering features, showing an overall pattern of "central clustering and peripheral dispersion," with localized emphasis on a "central urban area dominance with multiple core peripheral clusters" layout; 2) The accessibility level of sports facilities is relatively good, with noticeable differences between different districts, spatially indicating "higher in the central region, lower in the peripheral region," and directionally displaying a "higher in the west, lower in the east" trend. Recommendations from the study include ensuring new sports facilities align with human concerns in positioning and layout, enhancing the quality and efficiency of existing sports facilities, exploring sports facility spaces in other urban areas, and recognizing the significant benefits of grassroots sports facilities and transportation networks.

In the new journey towards the Chinese path to modernization, incorporating mass sports into the National Games is not only an inevitable requirement for deepening the national strategy of fitness-for-all and promoting the high-quality development of mass sports, but also an important opportunity to promote the comprehensive and coordinated development of the sports industry. By employing research methods such as literature review and logical analysis, this study analyzes the value implications, practical considerations, and future directions of mass sports events in the National Games during the process of the Chinese path to modernization. The research suggests that the National Games mass sports events are an important means to implement the national strategy of "fitness-for-all", a crucial link in building a higher-level public service system for fitness-for-all, a unique platform for promoting the Chinese sports spirit and healthy lifestyle, and an effective carrier for promoting individual comprehensive development and social harmony. However, there are challenges such as imbalanced allocation and inefficient utilization, weakened sense of experience and achievement, insufficient spiritual guidance and brand building, and obstacles to inclusivity and participation. Looking ahead, we must adhere to strategic guidance and integrate into the overall national situation; persist in optimizing efficiency and activating resource allocation; uphold the people-first principle and strengthen participation incentives; persist in cultural soul-building and telling the stories of the masses well; and adhere to prioritizing inclusivity and expanding coverage depth.

As the highest-level and largest-scale comprehensive sports event in China, the National Games have witnessed and led the glorious journey of Chinese sports. The research holds that the theme slogan is the core carrier of the spirit of the National Games. It not only condenses the social demands of different historical stages but also profoundly reflects the evolution trajectory of China's sports industry. Since the theme slogan of the National Games was launched, it has mainly gone through three stages: "serving national construction", "demonstrating national strength"and "sharing development dividends". It is an objective portrayal of the changes in the background of China's sports development, a presentation of the evolution of China's sports development concepts, a code expression of the inheritance and innovation of the Chinese sports spirit, and a realistic carrier for guiding and mobilizing the dissemination of values. This is specifically reflected in the intrinsic value color of adhering to the Party's cultural and ideological guidance, the inherent value color of upholding the principle of "putting people at the center", the value expression quality color of conforming to the pace of the value shift in Chinese sports, and the value demonstration color of holding high the banner of innovation and characteristic development. This further highlights the leading role of the National Games in promoting the modernization process of Chinese sports.

The 15^th National Games of the People's Republic of China (hereinafter referred to as the "15^th National Games") is not only an in-depth test of the coordinated development capability of the Guangdong-Hong Kong-Macao Greater Bay Area, but also poses a challenge to the traditional legal practice model based on a single jurisdiction.The practice risks of lawyers in cross-border sports events stem from the professionalism of sports legal services, the diversity of the legal relationships involved, and the particularity of cross-jurisdictional operations. In the fields of event commercial development, protection of the rights and interests of athletes and relevant personnel, cross-border data flow and personal information protection, employment relations arising from cross-border personnel movement, and event dispute resolution mechanisms, high requirements are placed on lawyers' professional capabilities, and considerable practice risks are also inherent.Lawyers shall bear liability for compensation if they cause losses to clients due to their faults. When engaging in the drive to build a leading sports nation and a rule-of-law bay area, lawyers must remain highly vigilant about the inherent risks of cross-border practice and proactively enhance their risk prevention awareness.

As a key practice in regional sports integration and development, the joint hosting of sports events in Guangdong, Hong Kong, and Macao plays a pivotal role in reconciling differences in legal systems and resolving cross-domain conflicts in sports event market development. This research provides a vivid practical example and innovative testing ground for promoting regional sports governance collaboration. Using literature review, rule analysis, case analysis, and comparative research, this study identifies the legal difficulties currently facing the market development of sports events in the three regions: difficulties in cross-jurisdictional protection of event logos, obstacles to cross-jurisdictional transfer of event intangible assets, and the dilemma of efficiently resolving cross-jurisdictional disputes. By systematically examining the practical explorations of the 15^th National Games in terms of organizational coordination mechanism innovation, cross-jurisdictional coordination and differentiated adaptation of rules, and cross-jurisdictional dispute resolution, and drawing on the core principles of regional rule of law development theory, this study proposes a breakthrough path for legal collaboration in the development of the joint hosting of sports events in the post-National Games era. This research requires a systematic solution based on four dimensions: tool empowerment, rule coordination, mechanism connectivity, and subject interaction.

In the era of digital economy, strengthening the legal protection of data rights and interests of sports enterprises in China has also become an important lever to promote the construction of sports and digital rule of law. By comprehensively utilizing literature review, logical analysis, and other methods, this study explores the legal dilemma and resolution path of data rights protection for sports enterprises in China. Research suggests that sports enterprise data has been widely applied in fields such as national fitness, sports industry, competitive sports, youth and school sports, and sports science research. However, there are currently four legal dilemmas: in terms of legislation, legislation on sports enterprise data rights lags behind protection practices, and local legislation lacks unified standards; In terms of law enforcement, the subject of data supervision for sports enterprises needs to be clarified, and there is a lack of data supervision basis based on application scenarios; In terms of justice, the difficulty in collecting data evidence has led to infringement disputes, and the judicial supervision mechanism for sports enterprise data has failed; In terms of compliance, sports enterprises have a vague awareness of self-protection of data rights and interests, and their data security and compliance systems are lagging behind. In view of this, it is necessary to coordinate legislation between the central and local governments, and improve the legal and regulatory system for sports enterprise data rights and interests; Promote the adaptation of law enforcement work and improve the data law enforcement supervision system for sports enterprises; Intensify judicial protection efforts and optimize the judicial protection system for sports enterprise data rights and interests; Cultivate the awareness of legal compliance among stakeholders and establish a data compliance system for sports enterprises.

The 15^th National Games serve as an important means to promote the micro-renewal of cities in the Guangdong-Hong Kong-Macao Greater Bay Area. By applying research methods such as literature review and logical analysis, this paper studies the historical experience, theoretical mechanism and practical approach of the 15^th National Games in promoting urban micro-renewal. Research suggests that since the new era, the National Games have conducted practical explorations on the coordinated mechanism of event preparation and urban renewal, the collaborative path of venue construction and the activation of urban existing space, the experience and enlightenment of the balance between continuous event investment and social benefits, and the integrated practice of the implantation of sports spirit and the inheritance of local cultural context. The 15^th National Games mainly promoted the micro-update of the governance system through the upgrading of event organization, the micro-update of the built environment through the construction and renovation of venues, the micro-update of industrial functions through the injection of sports capital, and the micro-update of community culture through the development of mass fitness. Based on the actual development of the Guangdong-Hong Kong-Macao Greater Bay Area, it is proposed to innovate the collaborative mechanism and break through the governance barriers of cross-border renewal, unleash the momentum of the event and activate the functions of the remaining space after the competition, integrate green intelligence and reconstruct the spatial network of ecological cities, deeply cultivate the sports genes and carry forward the cultural heritage of Lingnan.

The National Games in 2025 being jointly hosted by Guangdong, Hong Kong and Macao for the first time is a big step in the coordinated development of the Guangdong-Hong Kong-Macao Greater Bay Area. The game has aroused wide concern at home and abroad. As a major emitter of carbon dioxide, the reduction of carbon emission have similarly drawn international attention. Based on this, this paper uses the quasi-natural experiment method to carry out an empirical test of the carbon emission reduction effect of the 2010 Asian Games based on an urban panel data from 2005 to 2019, aiming to provide reference for the carbon neutral management of the 15^th National Games. The empirical results are as followed. ①The carbon emission reduction effect of the host city was significantly greater than that of the co-host city. ②Hosting the Asian Games had positive influence on the carbon emission reduction performance by optimizing the road traffic system and promoting the upgrading of industrial structure, but had negative influence by establishing tourism city brand. ③With the improvement of regions' technology level and residents' educational level, the carbon emission reduction effect of hosting the Asian Games is becoming more and more significant. The paper proposes to take low carbon supply and low carbon demand as guidance to provide reference for accelerating the realization of carbon reduction in the 15^th National Games.

The 15^th National Games of the People's Republic of China, jointly hosted by Guangdong, Hong Kong, and Macao, is bound to become a strategic fulcrum for promoting regional coordinated development and deepening the integrated construction practice of the Guangdong-Hong Kong-Macao Greater Bay Area in the context of the new era due to its special geographical location. This paper, based on the multi-center governance theory, systematically examines the mechanism of action and practical path for promoting the in-depth "Five-in-One" integration of the Greater Bay Area through methods such as literature review and logical analysis. The research reveals that the sports interaction among Guangdong, Hong Kong, and Macao has gone through five development stages: emotional bonding, economic driving, institutional integration, deepening and expansion, and strategic integration, which reflects a profound transformation from separate control to strategic integration. The organizational structure of the 15^th National Games under the framework of "one country, two systems, and three legal regions" represents an institutional innovation for the Greater Bay Area to construct a collaborative governance model, and its value is manifested in five dimensions: politics, economy, culture, society, and ecology. However, the preparation for the Games faces structural challenges such as institutional differences, uneven resource allocation, divergence of values, obstacles to social integration, and lack of a sustainable mechanism. Accordingly, this paper proposes strategies such as improving the cross-regional collaborative governance mechanism, optimizing the allocation of regional elements, creating a shared cultural identity space, constructing a long-term exchange platform, and innovating a green and low-carbon model for hosting the Games, aiming to transform the 15^th National Games from a "one-time event" into a "sustainable platform" for promoting the in-depth integration of the Greater Bay Area.

To promote the integration of Hong Kong and Macao into the national development framework and to build a world-class bay area, this study explores the holistic governance of the 2025 National Games in the Guangdong-Hong Kong-Macao Greater Bay Area. Using literature review and logical analysis methods, it examines the current situation and value orientation of holistic governance in the Games and proposes practical governance pathways. The study identifies four major value orientations: transforming economic vitality into economic growth, advancing coordinated development and urban agglomeration, enhancing cultural exchange and cultural industry development, and empowering regional innovation through technology. Accordingly, it suggests governance pathways that leverage sports to stimulate economic vitality, promote synergy to build a world-class city cluster, empower culture to co-create the “Humanistic Bay Area” event brand, and integrate technology to foster innovation and construct a Smart Sports Bay Area.
