At present, building a philosophy and social sciences discipline system, academic system, and discourse system with Chinese characteristics based on Chinese practice is a major contemporary proposition that highlights the true power of contemporary Marxism, showcases China's cultural strength and international competitiveness. After 40 years of development, sports sociology research in China has achieved great results and made contributions to sports reform and development. However, the fundamental gap in the middle level theory, which is the core of the academic system, is quite prominent. This article takes literature research as the main method, and from the perspective of the construction of the academic system of sports sociology, outlines the history of the development of sports sociology in China. It clarifies that the construction of middle level theory is the only way to localize sports sociology, and proposes to practice academic consciousness, strengthen the disciplinary identity of researchers Exploring practical paths for the construction of middle level theories in sports sociology, such as building an academic community and promoting organizational guarantees for the construction of middle level theories.

Objective: To explore the intervention effect of Tai Chi push hand（TCPH） exercise on knee osteoarthritis (KOA).Method: 50 KOA patients were recruited from the community and randomly divided into control group（N1=25）and TCPH group（N2=25）. The control group received unsupervised exercise rehabilitation guidance; TCPH group received rehabilitation training mainly focused on Tai Chi Pushing Hands, with 3 sessions per week for 90 minutes each time. Before and after 12 weeks of intervention, test data were collected from two groups of patients for pain visual analogue scale (VAS), Lysholm knee score scale（LKSS）, lower limb strength, Y-balance test (YBT), and Depression Anxiety and Stress Scale (DASS-21) .Result: Before intervention, there was no statistical difference in all indicators between the control group and the TCPH group. After 12 weeks of intervention, there was no statistically significant difference in all indicators before and after the control group (P>0.05). The VAS, LKSS, lower limb strength, and YBT results of the TCPH group were significantly better than before the intervention (P<0.001). The scores of depression, anxiety, and stress on the DASS-21 scale were lower than before the intervention, and the difference was statistically significant (P<0.05); After 12 weeks of intervention, compared with the control group, the TCPH group showed significant differences in VAS, LKSS, and YBT results (P<0.001); There was a statistically significant difference in the comparison of lower limb strength and the three dimensions of the DASS-21before and after (P<0.05).Conclusion: The Tai Chi Pushing Hand Exercise Program can reduce the degree of knee joint pain, improve knee joint function, dynamic balance, and mental health in patients with knee osteoarthritis.

The consciousness of the Chinese national community is a sense of group belonging and a concept of a shared destiny based on cultural identity. Traditional sports rituals, using physical practice as a medium, construct a cross-regional, trans-dialectal cultural identity field. The shared symbols, emotional resonance, and physical dialogue in their ritual performances effectively bridge the identity fissures caused by geographical separation, linguistic differences, and memory fragmentation. By leveraging traditional sports rituals to deeply explore the inherent logic of “symbolic representation,” “historical roots,” and “spiritual consensus” in strengthening the consciousness of the Chinese national community, and by exploring the educational pathways through which traditional sports rituals reinforce this consciousness, we can not only form a systematic theoretical framework and practical paradigm but also facilitate a qualitative leap in the recognition of Chinese culture-from superficial symbolic cognition to deep internalization of values. Furthermore, this approach helps build an internationally influential discourse system for the dissemination of traditional sports culture, thereby providing solid cultural support and practical pathways for strengthening the consciousness of the Chinese national community.

Based on literature research, this article provides a comprehensive review of the development trajectory, research achievements, and future trends of Chinese sports sociology since the reform and opening up. We have observed that Chinese sports sociology has undergone a process of evolution from its introduction and establishment phase to rapid growth and onto a phase of disciplinary introspection. During this period, research themes have become increasingly in-depth, diversified, and specific, with a particular focus on mass sports, sports and development, and sports and politics. These focal areas not only reflect the trends and societal demands of sports development during the period of social transformation but also highlight a profound concern for specific groups, social issues, and management systems. From a theoretical perspective, the analysis has evolved from early Marxism and functionalism to a mid-term integration of functionalism, conflict theory, and interactionism, demonstrating significant interdisciplinary characteristics. The research methods have shown a trend from early quantitative approaches to an increasing application of qualitative research methods. Looking to the future, Chinese sports sociology should deeply integrate theory with practice, emphasizing the diversification of research methods to achieve a balanced development of humanistic care and scientific spirit. Simultaneously, it should continue to explore and innovate in the areas of sports discipline localization and internationalization, technology application, and interdisciplinary research. This is to adapt to the new demands of the era's development, promote the prosperity and progress of the sports discipline, and contribute its unique value to a broader academic knowledge domain.

This study focuses on Hong Kong residents and employs research methods such as literature review, questionnaire surveys, and mathematical statistics. It examines the relationship between pre-competition outcome perception, event support, and national identity among Hong Kong residents regarding the 15th National Games, using social exchange theory and social identity theory as theoretical perspectives and based on the overall framework of "Stimulus → Organism → Response" of the S-O-R theory. The findings indicate that positive outcome perception formed by Hong Kong residents before the 15th National Games has a significantly positive impact on their event support and national identity; negative outcome perception has a significantly negative impact on event support and national identity; and event support has a significantly positive impact on national identity. The study suggests strengthening the favorable influence of positive outcome perception to form event support and shape the emotional space of national identity; weakening the adverse impact of negative outcome perception to consolidate event support and maintain the psychological foundation of national identity; and using event support as a catalyst to enhance national cohesion and social belonging.

National fitness facilities not only provide a place for all people to work out, but also provide a field for fitness seekers to seek social role identity. Questionnaires, interviews and qualitative comparative analysis were used to analyse the main factors influencing the efficiency of the use of national fitness facilities. The results show that no single factor is a sufficient condition for the continued use of fitness facilities by the public, but is the result of a combination of factors, among which peer effect, feedback channels, fitness environment and fitness expectations are the key factors affecting the efficiency of the use of fitness facilities. In order to better revitalize the stock of fitness resources, based on the analysis of the main factors influencing the use of national fitness facilities, it is proposed to strengthen top-level planning and design to promote the formation of a good fitness atmosphere, improve formal and informal information feedback mechanisms to enhance collaborative governance, build ecological fitness spaces embedded with multiple elements to meet diversified fitness needs, and enhance the public's active fitness through connotative development and outreach drive. The aim is to enhance the public's awareness of fitness through connotative development and outreach.

The emergence of short video platforms has given rise to sports short videos as a novel mode of communication, garnering substantial user attention. This study seeks to explore the determinants impacting user satisfaction with sports short videos in order to enhance the viewing experience and foster sustainable development. Through purposeful interviews with 40 sports short video users and analysis using grounded theory methodology, an influential factor model affecting user satisfaction was developed based on SOR theory. The findings reveal that subject factors, platform construction, and talent ability significantly influence user satisfaction, with subject factors serving as the direct driver of positive user reactions while platform construction and talent ability act as external stimuli. Based on these findings, it is recommended to meet users’ psychological expectations; enhance the quality of systems and resources within sports short video platforms; attend to users’ emotional needs; cultivate innovation and interactive consciousness among sports short video talents; bolster user engagement; optimize transmission paths and means for sports short video content.

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.

The participation level of mass sports is of great significance to the construction of the sports power and a healthy China. As a place of daily life, community is one of the important environments that affect residents' physical exercise.Based on two waves of China Family Panel Studies , this paper analyzes the influence of neighborhood perception characteristics in 2016 on different levels of sports participation of urban residents in 2018. The results show that： the proportion of urban community residents who occasionally participate and regularly participate in physical exercise is 55.62%, more than 44.38% who do not participate。Compared with regional characteristics （public facilities, surrounding environment, surrounding security）, social characteristics （neighborhood relationship, neighborhood help, community affection） have more significant positive effects in different degrees.Heterogeneity effect shows that, regional characteristics can significantly improve the level of occasional participation of male, youth and low-income groups, while the significant positive influence of social characteristics is more extensive.Based on the research, it is proposed that to promote the residents' sports participation at a higher level from the community level, we should not only pay attention to the regional characteristics, but also pay attention to the social characteristics.

Objective： The technical and tactical performance of badminton players with different handed was compared to analyze the difference in game between different handed and two right-handed players, the difference in technical and tactical performance between left-handed and right-handed players and the influence of left-handed players on opponents （right-handed）. Methods： Match observation method and mathematical statistics were used to analyze 40 high-level women's singles badminton matches, comparing the overall characteristics of the two groups and the differences in hitting positions, technique, routes and landing points of the four groups of players. Results： There is no significant difference in the average score per game, the average number of strokes per rally of two forms and the nature of scores and losses of four groups of players; There are significant differences in hitting positions, hitting techniques, hitting routes and hitting landing points between the groups of players. Conclusion： In the high-level women's singles badminton competition, the technique and tactic of the left-handed players are different from those of the right-handed players, which will also cause some changes in the opponent's technique and tactics, but the existence of the left-handed players does not change the overall scoring and hitting pattern in women's singles game. Due to the specificity of left-handed players, additional adaptive training for left-handed players should be added; It is best to treat the right-handed and left-handed players differently or adopt reasonable treatment methods to improve the accuracy of the analysis results.

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.

By aid of the method of document literature, in accordance with the theory of "comprehensive development of humans" of Marxism, review the value and significance of sports in it.Make a general survey of the theoretical formation and ideological implication of the theory of "comprehensive development of humans" of Marxism, The human development is not a development of one-sided,abnormal and single, but is a multiple dimensions development which contains physical power and intelligence, capability and demand, personality and freedom, wherein, sports is the important dimension for the "comprehensive development of humans". The theory of "comprehensive development of humans" is a historical evolution process of social formation, in the “human's mutual reliance”, sports is the revolt for slavery;in the "humans reliance on things", sports is the rescue for alienation;and in the "comprehensive development of individuals", sports is the important factor for life harmony and unity, which can make humans obtain the human character of "well-rounded person". Moreover, the internal drive of life triggers the demand of humans for sports;the life endowment seeks for the free and personalized sports capability;the life presentation advocates the sports practices in social relationship;and the life demonstration realizes the sports value of complete character, the "comprehensive development of humans" needs to give play to the special existing essence of humans while sports is the life establishment and survival choice to realize the "well-rounded person".

As one of the key industries in the Greater Bay Area (GBA), sports industry has ushered in a good opportunity to accelerate development under the new development pattern of double circulation, and presents a gathering development trend. This research uses the methods of literature analysis, interview, deduction and induction, explore the dynamic factors of sports industry agglomeration in GBA under the new development pattern of double cycle, reveal the driving mechanism of sports industry agglomeration, to provide theoretical and empirical reference for the formation and development of sports industry agglomeration in GBA under the new development pattern of double cycle. The results show that, under the new development pattern of double cycle, the dynamic factors of sports industry agglomeration in GBA mainly include five aspects: resource support, industrial supply, market demand, attraction of innovation factors and government regulation. From its driving mechanism, based on resource support and government regulation, through coordinated power generation and two wheel drive on both sides of supply and demand, unblock the internal circulation of the sports industry and drive the external circulation, at the same time, by creating an innovation driven highland “led by science and technology”, promote the transformation of regional sports industry agglomeration from factor driven to innovation driven, build a sports industry space system with sports industry agglomeration as the core.

The cultivation of body consciousness is of great significance for strengthening the youth sports work and promoting students to play an active role in sports activities. By using the methods of literature, speculative research and logical analysis, on the basis of analyzing why it is difficult for teenagers in China to establish body consciousness, this paper points out the specific improvement strategies, found that： （1） In the context of sports, body consciousness is a mental state in which people perceive, pay attention to and care for themselves in the process of related behaviors, which can actively feedback sports practice. （2） Body consciousness is very important in the process of sports activities, but it is difficult for teenagers to recognize. The main reasons lie in three aspects： the original difficulty of "absent presence" of body, the disadvantage of lagging educational concept and the pain of alienation of lifestyle. （3） The urgent task to be solved in current youth sports and school sports is to focus on cultivating youth's physical awareness. Its basic strategy should be based on physical education as the logical main line, with opposing meditation as one body and two wings, compulsory sports as a necessary measure, qualitative evaluation as the main evaluation method, actively promoting the three-level linkage and cooperation of schools, families, and communities. If conditions permit, it is also possible to try to introduce fitness programs.

On the basis of established research, combining the characteristics of China's governmental organizational behavior, we propose an integrative analytical framework for understanding the differences in the level of development of China's national fitness public services, and use fs/QCA to conduct a group analysis of the cases of the development of national fitness public services in China's 31 provincial regions, with the aim of revealing the complex interactive mechanism of the factors influencing the level of development of the national fitness public services, in order to seek differentiated driving paths to promote the high-quality development of national fitness public services. It is found that there is no single necessary condition that explains the results of the development of national fitness public services, whether for the development of high-level national fitness public services or for the development of low-level national fitness public services. There are three driving modes for the high-level development of national fitness public services in China, namely, "technology-enabled", "policy-fiscal balance" and "fiscal-technology synergy".

The 1976 Montreal Olympic Games was of great epoch-making significance in world sports history. The financial crisis it caused to Montreal not only changed the development and hosting mode of the Olympics, but, from a political and diplomatic perspective, the topic of “China's representation”, also involved the International Olympic Committee, Canada, the United States, China, and Chinese Taiwan in complex political disputes, which had a significant historical impact. Due to the fact that New China did not participate in this Olympic Games, the political controversy surrounding China around the world is rarely recorded domestically. Using the latest declassified English original files from the UK, the Canadian Department of Foreign Affairs, the State Department, the CIA of the USA and the International Olympic Committee, the historical background and process of the “Montreal Controversy” focusing on the “representation of China” from the perspective of “others”, the historical origin of the international sports event, how it interacted with the international relations at that time, the political demands of all stakeholders involved, diplomatic considerations The profound impact of the mediation game and its final outcome on the International Olympic Committee, China US, and China Canada relations, as well as the turning point changes in China's sports diplomacy.

This study employs the perspectives of literature analysis, historical analysis, and spatial philosophy to examine the landscaped characteristics of stadiums as sites of collective memory and political identity. The findings reveal that stadiums are not merely physical spaces but also significant venues for collective memory and political identity, shaped by sporting events, ceremonial activities, and landmark architecture. However, in the contemporary era, stadiums exhibit three fractures in their capacity to sustain collective memory: the disjuncture between large-scale events and everyday rituals, the disconnect between monumental landmarks and lived spaces, and the misalignment of collective memory between major events and iconic structures. These fractures hinder stadiums from effectively preserving collective memory and fostering political identity. To address this issue, the study proposes recommendations across three dimensions—temporality, scale, and alignment: emphasizing processuality in time, bridging the micro and macro scales, and reinforcing the referentiality between bodily performances and spatial symbols. These recommendations aim to achieve continuity and coherence in collective memory and the embodiment of political identity, offering a novel perspective for understanding and realizing the cultural significance and value of stadiums. The study provides insights for contemporary research in the sociology of stadium spaces and their practical construction.

Under the background of building a sports power, technological innovation ability has become the main constraints that restrict the development of Chinese sports industry, strengthening the research on the optimization and implementation of industrial technology innovation policy is not only the key to the development of sports industry, but also happens at the right time. Using literature research methods, inductive and deductive methods, logical analysis methods, establish a dynamic game model of incomplete information with the government and sports enterprises as the main game subject, discuss and explain the strategic behavior of the two game subject in the process of optimizing and implementing industrial technology innovation policies from the perspective of dynamic games, provide a scientific basis for the government to rationally optimize the sports industry technological innovation policy and implement it well. Research shows that： in the process of optimization and implementation of technical innovation policy, the focus is to adjust the interest relationship between the government and sports enterprises, constrain the game behavior of these two core stakeholders. Furthermore, proposed a trinity-style industrial policy optimization path of “issue more detailed regulations on the promotion of sports industry, start the cleaning of lower level policy documents, and establish a linkage mechanism for the implementation of sports industry policies”, for optimizing the technological innovation policy of the sports industry and leading the sports industry to take the road of innovation drive, in order to promote the overall technological innovation level of our sports industry.

Musculoskeletal injuries occurring during military personnel training have a profound impact on their service longevity, combat readiness, and mission performance. A scientific and comprehensive injury prediction approach and reasonable and individualized training regimens can significantly reduce musculoskeletal injuries among military personnel. International studies formulate multifaceted injury prediction strategies mainly through a combination of optimized functional movement assessments and physical fitness tests to identify and anticipate the injuries during military training. Paired with a pragmatic and tailored injury prevention training program including warm-up routines, adaptive exercises, and training load monitoring, these measures prove highly effective in preventing musculoskeletal injuries in military personnel, thereby safeguarding their sustainable combat capabilities. In light of these findings, it is recommended that domestic practices incorporate and adapt pertinent foreign injury prediction and prevention strategies and concepts based on the actual situation.
