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.

"Folklore" is a valued standard and an important symbol to identify and determine the authenticity of folk sports. Its study is conducive to the continuous inheritance and orderly development of folk sports in China. Based on in-depth interviews with 30 inheritors and performers of Xuwen Tengpai Gongban Dance, this research uses the method of grounded theory to construct a conceptual characteristic model of "folklore" in folk sports. The model shows that symbolic rituals are the media hub for the dialogue between humans and gods, multiple inheritance is the practical field for continuous inheritance, living state rheology is the concrete carrier of form reconstruction, integration and symbiosis are the value pursuit of high-quality development, and customs and regulations are the normative Institutional guarantee for training ethnic groups. The research suggests to build a "memory field" to activate the collective memory of folk sports symbolic ceremonies; to maintain the stability of the shared field and expand the diversified inheritance mechanism of folk sports; to grasp the law of change and systematize folk sports in the dynamic flow" Reproduction"; to maintain the symbiotic model, and seek high-quality development of folk sports in a framework system of integration and symbiosis; continue to "interact with etiquette and customs", highlighting the important role of folk sports in rural social governance. This model extracts the "folk-custom" gene of folk sports, and provides a valuable reference for building an independent discourse system of folk sports in my country, broadening the theoretical boundaries of folk sports research, and improving its theoretical system.

The construction of the modern civilization of the Chinese nation is the aim of the inheritance and development of the traditional sports of the Chinese nation,and the inheritance and development of the traditional sports of the Chinese nation is the effective way to construct the modern civilization of the Chinese nation, in the process of chinese-style modernization, both of them are in harmony with each other and have two-way constructiveness. The traditional sports of the Chinese nation should stand in the dimension of“History” and“Modernity”, adhere to the innovative development of the traditional sports of the Chinese nation under the guidance of the thought of socialism with Chinese characteristics in the new era, the construction of modern civilization of the Chinese nation should be guided by socialist core values, rooted in the soil of Chinese civilization, stick to positive innovation, and make great efforts to develop traditional national sports culture with Chinese characteristics Highlighting the“People-centered” value orientation of national traditional sports, promoting the all-round development of human beings and constructing a new form of social civilization; To help build a harmonious society between human beings and nature; to grasp the characteristics of Chinese civilization, to promote the integration and coexistence of traditional national sports and modern Chinese civilization in the process of modernization; to promote exchanges and exchanges among various ethnic groups in the process of integration, inheriting and carrying forward the Chinese excellent traditional sports culture has gradually become an important driving force to construct the modern civilization of the Chinese nation.

By using research methods such as literature review, historical research, and logical analysis, based on the definition of the concept of "Two Finger Zen", it is found that the origin and interpretation of "Two Finger Zen" in Chinese martial arts originated from Li Sau's "Parallel Finger" skill during the Jin and Yuan dynasties, formed from the "Practice of Zen with Fingers" of the consistent Zen master at Shaolin Temple, and enriched the "Pictographic Finger Skill" of Shaolin Five Fists during the Ming and Qing dynasties, As well as the martial arts stunt "Two Finger Zen" that developed after the New China era, it has continuously evolved, integrated, and progressed in the long history of Chinese civilization, forming a relatively complete training system for martial arts.Contemporary two finger Zen mainly has the value of cultivating the body and mind, the value of self-defense and rescue, and the artistic value of the evolution of the times. To achieve the protection of the culture of the Second Finger Zen, it is necessary to enrich the connotation of the Second Finger Zen, establish a sound academic system, increase the inheritance and protection of the intangible cultural heritage of the Second Finger Zen, implement the integration of martial arts and Taoism, strengthen the talent cultivation strategy of the Second Finger Zen, highlight the characteristics of martial arts disciplines, attach importance to the competition and performance activities of the Second Finger Zen, and demonstrate the confidence of Chinese culture.Only by integrating the essence of the two finger Zen with the excellent traditional Chinese culture can this martial arts stunt truly make the past serve the present, bring forth the new, constantly enhance the spread and influence of Chinese culture, inject civilization nourishment into the high-quality development of Chinese path to modernization, contribute spiritual strength, and demonstrate the charm of Chinese culture in the world culture turmoil.

The logical exploration of the discourse construction of modern Chinese Wushu "strong seed to save the country" from the three dimensions of history, theory, and practice helps to deeply understand the internal logic and deep context of the discourse construction of modern Chinese Wushu "strengthening species to save the country". Using multiple historical materials for mutual verification and the method of integrating history and logic, based on the perspective of discourse construction, with the Central Guoshu academy as the center, this paper explores the triple logic of the discourse construction of modern Chinese Wushu around the core discourse of "strengthening species to save the country". From a historical logic perspective, under the joint influence of the metaphor of "the sick man of the country" and the symbol of "the sick man of the body", the trend of advocating Wushu to strengthen oneself is the logical starting point for the construction of the discourse of "strengthening species and saving the country" in modern Chinese Wushu. From a theoretical logic perspective, in the context of saving the nation from extinction and striving for survival, from the three levels of the country, nation, and society, it is hoped that the goal of national rejuvenation and national prosperity can be achieved through the expropriation of the national body, adherence to national sports, and discipline of Wushu human bodies. This is the logical mechanism for constructing the discourse of "strengthening species to save the country" in modern Chinese Wushu. From a practical logic perspective, in the narrative of the historical theme of saving the country through traditional Chinese Wushu, the Central Guoshu academy has activated the recognition mechanism of national martial arts values through various measures, adhered to tradition to build the ideological foundation of national Wushu culture confidence, promoted the construction of national cultural symbols and reshaped the national image internationally, which is the logical path for the construction of the discourse of "strengthening species to save the country" in modern Chinese Wushu. Based on the study of the discourse construction of modern Chinese Wushu "strengthening species to save the country", it is proposed that Chinese Wushu should be fundamentally guided by the will of the state, based on the logical basis of the isomorphism of the body and the country, and follow the contemporary inspiration of the development path of people's health and national strength.

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".

This paper reviews the development and internal characteristics of sports tourism academic research in China in the past 30 years by literature method, knowledge graph visual analysis method, mathematical statistics method, and logical analysis method. It has gone through stages of germination, growth, moderation and prosperity, the research content, evolution path and research hotspot of sports tourism show a good trend of development. However, there are also some problems, such as insufficient research on industrial integration, the insufficient academic focus, the disconnection between theory and practice, and empirical research is just beginning. Based on this, it is proposed that the research direction of sports tourism should still be further expanded and a core theoretical structure system should be established; focus on the new demands and new trends of consumption upgrading; pay full attention to the issue of ecological civilization in development practice; serve and base on the "real problems" in the practice of sports tourism; emphasis both quantitative and qualitative in order to strengthen empirical research.

Using the methods of literature and logical analysis, this paper probes into he historical venation, logical mechanism, operating system and realizing path of the integration and development of sports and art. The research holds that the relationship between sports and art has gone through the development process of form-shadow dependence, separation and differentiation, one-off and the other, re-coupling and fusion and innovation, and that there is a deep-seated logic mechanism in the fusion of sports and art, it follows the educational logic of five-education, the industrial logic of upgrading business forms and assets, the social logic of increasing demand and consumption, and the innovation logic of increasing technological ability and value. Based on the study, the running system of sports-art fusion is constructed from four aspects： fusion power, fusion mechanism, fusion mode and fusion pattern, from the concept of guidance, mechanism innovation, science and technology, talent support four dimensions of the planning of the integration of physical and artistic development path. The study suggested that the integration of superior resources with the concept of big integration to promote the integrity of innovation in the integration of Sports and arts;the integration of multiple forces to achieve synergy in the integration of Sports and arts with the department to pool;and the expansion of presentation channels with the support of Science and technology, to enrich the form of expression of the integration of sports and arts;to promote and deepen the education system, tamping the foundation stone of the integration of sports and arts.

The TOE framework is introduced, and the fuzzy set qualitative comparative analysis method （fsQCA） is used to reveal how digital empowerment affects the governance performance of public services for national fitness. 31 provincial-level administrative regions in China are used as case samples, multiple configuration paths are constructed from three levels of technology, organization. The results show that： There are 6 configurations that produce high governance performance of national fitness, which include technology dependent mode, technology & financial resource driven mode, financial resource driven mode by mild policy promotion, organizational driven mode under soft external environment pressure, organizational driven mode under policy dependence, internal and external joint driven mode. The internal and external joint driven mode has played a more important role in promoting the high governance performance of national fitness. The financial resource driven mode by mild policy promotion and organizational driven mode under external environment pressure are followed by. There are multiple equivalent combinations in the process of digital improving governance performance for national fitness, and there is a substitution relationship between different factors. The financial resource capacity and attention allocation within an organization play important roles in achieving high governance performance in national fitness.

The 20th National Congress of the Communist Party of China （CPC） emphasized the need to enhance the well-being of the people and improve the quality of life of the people. Leisure sports, as a mass sports activity engaged by people with rich lives in their leisure time, are developed in line with the pursuit of physical and mental health of the living body, in line with Healthy China and the National Fitness Strategy. This study adopts the method of literature and logical analysis to systematically analyze the opportunities and challenges encountered by leisure sports in improving people's livelihood and well-being, to determine the future direction and path according to the challenges, and to realize the reconstruction of leisure sports on people's livelihood and well-being. The research holds that leisure sports can continuously satisfy people's pursuit of a better life through the reconstruction of a sense of gain, happiness, and security. Meanwhile, the gradual improvement of the sports policy system, the continuous improvement of the health literacy of the whole people, the increasing requirements for the quality of life, more convenient sports venues and facilities, and the steady and harmonious development of the society have brought new opportunities for the development of leisure sports. However, a series of practical problems such as the imperfect sports equity guarantee system, lack of sense of gain, change of modern lifestyle, decline of happiness, obstruction of the operation mechanism of a better life, and diminished sense of security have also brought challenges to its development. In the future, we can open up a new path for the leisure sports industry by constructing a sports equity mechanism, making the sense of gain more substantial, improving life satisfaction, making happiness more secure, realizing the yearning for a better life, and making the sense of security more sustainable.

The digital era provides new opportunities for the high-quality development of the sports industry, but the mechanisms through which digitalization level and institutional environment influence this development are not yet clear. Based on this, this study explores the impact of digitalization level on the high-quality development of the sports industry and the moderating effect of the institutional environment using panel data from 30 provinces （cities） in China from 2013 to 2021. The findings of the research are as follows： （1） The digitalization level can significantly promote the high-quality development of the sports industry, and this conclusion remains valid after a series of robustness tests. （2） Mechanism analysis shows that the institutional environment has a U-shaped moderating effect on the relationship between digitalization level and the high-quality development of the sports industry. （3） Regional heterogeneity analysis reveals significant regional differences in the promoting effect of digitalization level on the high-quality development of the sports industry. Specifically, compared to the eastern region, the positive effect of digitalization level on the central region is more significant, while it is not significant for the western region. Therefore, this study proposes suggestions for improving digitalization level, comprehensively optimizing the institutional environment, and promoting digital construction according to local conditions, in order to further promote the high-quality development of the sports industry.

In order to investigate the influencing mechanism of marathon tour's revisit willingness, using the literature method logical analysis method and other methods, the airtical analyzed the influencing mechanism of tourists' revisit willingness by introducing the "push-pull" model, and basing on the four semiotics main lines of marathon tour's landscape symbols, consumption symbols, service symbols and project symbols. The results show that marathon tourism landscape symbols, consumption symbols, service symbols and program symbols have significantly positive effects on tourists' perceptions. Tourist perception has significantly positive effect on tourists' willingness to re-visit. Tourist perception plays a completely mediating role in the process of influencing mechanism of marathon tourism landscape symbols, consumption symbols, service symbols and program symbols with tourists' revisit intention. Tourism landscape symbols, consumption symbols, service symbols and program symbols constitute the pushing mechanism and pulling mechanism of tourists' perception. Tourist perception is also completely involved in the influencing mechanism of tourists' revisiting intention, which together constitutes the influencing mechanism of marathon tour revisit intention.

The sports industry is a green and sunrise industry, which is very consistent with the five dimensions of innovation, coordination, green, openness and sharing in China’s high-quality economic development. On the basis of in-depth analysis of the connotation of high-quality economic development, this paper discusses the five dimensional impact mechanism of sports industry on high-quality economic development, and then empirically tests the five dimensional impact mechanism through the coupling degree model. In the empirical process, the data from 2011 to 2020 were selected. Through the calculation of coupling degree and curve analysis, it was found that the change of coupling degree between the sports industry and the five dimensions of high-quality economic development reflects the increasingly close relationship between the two. Among them, the sports industry has the highest coupling degree with coordinated development, while the coupling degree with shared development is low. The empirical results show that in order to promote the high-quality development of China’s economy, we must increase the development of sports industry and increase the proportion of sports industry in the national economy.

In the process of building a healthy China, the integration of physical and mental health is an important measure to advance the health barrier and achieve the transformation from "treating diseases as the center" to "putting people's health as the center". Under the realistic background of the deepening aging of the population, the continuous growth of the incidence of chronic diseases and the normalization of prevention and control of the COVID-19, Academician Zhong Nanshan talked about his fitness methods, sports and chronic disease prevention and control, the evolution of sports health integration and the promotion of sports health integration practice based on his own physical exercise practice and medical experience. Its main viewpoints have important guiding value for the development of theoretical research and practice on the integration of sports and hygiene in China in the future.

Sports health communication is an important way to promote the development of physical and mental health, which has far-reaching significance for comprehensively promoting the construction of a healthy China and improving people's well-being. In the present and future era of digital civilization, while enhancing technology dividends and empowering users, human-computer interaction may bring certain audience risks when it is integrated into sports health communication practice： language model relies on symbol generation communication, weakens tacit sports knowledge teaching,and Overshadowing the audience's physical cognitive practice; Simulation of neural network structure by deep learning, hinder the interaction of sports emotional experience, and promote the alienation tendency of audience emotion; Machine algorithm is used to strengthen iterative data analysis, eliminate the persistence of sports spirit and culture, and intensify the crisis of audience moral anomie. The construction of virtual space with meta-cosmic surreality fetters the communication of realistic meaning of sports and increases the hidden danger of audience’s cognitive ambiguity. Therefore, it is advocated to return to the embodied practice of sports health communication with body co-presence, promote the emotional communication of sports health communication with individual empathy, internalize the moral law of sports health communication with subject co-law, and construct the opinion market of sports health communication with group consensus, so as to achieve the future goal of promoting the all-round development of human health through sports health communication.

It is an important measure for the strategic development of sports and education integration to bring the cultivation of competitive sports reserve talents into the national education system. By using the methods of literature, social investigation and logical analysis to study the development impetus of the transformation of the cultivation of competitive sports reserve talents in China. The research found that the structure of motive force for the cultivation of reserve talents in competitive sports includes the main body of motive force, the process and means of motive force operation, and the goal of motive force operation; It shows power source dislocation, difficulties in power distribution and transformation, lack of power monitoring and evaluation standards, and differences in power operation target management thinking; In the new era, we should strengthen the construction of the power subject at the middle level, establish and improve various mechanisms, establish a scientific power monitoring and evaluation system, adjust the management thinking, and make the power operation objectives consistent, so as to achieve the purpose of providing appropriate power for the cultivation of reserve talents in competitive sports.

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.

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.

In order to study the issue of the training cycle of my country's “Three Big Balls” under the background of the integration of sports and education, the literature data method, logical analysis method, interview method and other research methods are used to discuss in depth the “Three Big Balls” in my country at this stage based on the life cycle theory. The cyclical problem of the whole chain of the training of reserve talents. Based on the in-depth analysis of the real difficulties in the training of reserve talents for competitive sports in the "Three Big Balls", the study puts forward the full chain cycle of talent training： basic training period, special growth period, professional docking period, ability jump period, and level stability period. Five specific training ideas are put forward. First, based on the basic training period of reserve personnel training, expand the number of "three big balls" reserve personnel; Second, based on the special growth period of the system to sort out the "three big balls" reserve talent delivery channels; Thirdly, explore the incentive mechanism of "three big Balls" reserve talents in combination with the career docking period of talent training; Fourth, relying on the "Sports Law" to achieve the "three big ball" reserve talent ability to improve the comprehensive guarantee; Fifth, from the perspective of life cycle to achieve the "three big balls" reserve talent level of stable period of continuation. This study aims at solving the realistic dilemma of the training of reserve talents in the professional process of our country, and provides support programs for the comprehensive revitalization of the "three big balls" in our country.

Objective:To make scientific and reasonable training plans for different training purposes by comparing the impact of different sprint interval training programs on aerobic and anaerobic abilities and analyzing the influencing factors from the perspective of skeletal muscle anaerobic metabolism. Methods:48 subjects were randomly divided into training method A (A, n=10) with an 8% resistance coefficient sprint for 30 seconds, training method B with a 9% resistance coefficient sprint for 30 seconds (B, n=9), training method C with an 8% resistance coefficient sprint for 45 seconds (C, n=10), training method D with a 9% resistance coefficient sprint for 45 seconds (D, n=8) for 4 weeks, 3 times a week, 5 times with an interval of 5 minutes' sprint interval training. Aerobic and anaerobic abilities test (CMJ, long jump, 30m, VO_2max), anaerobic power (3 indicators), muscle function testing including surface electromyography (8 indicators), isokinetic muscle strength (8 indicators) were tested before and after training. Results:① The impact of four types of SITs on aerobic and anaerobic test: Mode A can significantly improve the scores of long jump, 30m and VO_2max (P<0.05); Mode B can significantly affect the scores of CMJ, long jump, 30m and VO_2max (P<0.05); Mode C can significantly improve the scores of 30m and VO_2max (P<0.05); Mode D can significantly improve 30m sprint test (P<0.01); Mode ABD had significant difference in the increase of VO_2max (P<0.05); ② The effects of four SIT methods on aerobic and anaerobic capacity: MethodA screened 3 factors in anaerobic and isokinetic to explain their impact on power, with a contribution rate of 75.89%, while the non-screened factors for speed and aerobic capacity were explained; MethodB screened 3 factors from anaerobic, electromyography and isokinetic to explain their impact on power, with a contribution rate of 65.09%, and explained the non-screened factors of speed and aerobic capacity; MethodC can screen 3 and 5 factors from electromyography and isokinetic to explain the velocity and aerobic capacity, with a contribution rate of 82.28%; The D training method can screen 5 factors from electromyography and isokinetic to explain their impact on power and speed, with a contribution rate of 81.68%, which has limited effect on power improvement; ③The contribution rate of electromyography and isokinetic to the difference in aerobic and anaerobic test after four SIT methods is 37.15%, and no anaerobic factors can be selected for explanation. Conclusion:① A and B training with a sprint time of 30s can be used as power training methods; 4 kinds of SIT training can be used as training methods to improve speed ability; A, B and D training modes can be selected when improving aerobic capacity; ② Anaerobic and skeletal muscle factors can be used as important contribution variables to explain the effects of four kinds of SIT training;③The difference of aerobic and anaerobic abilities caused by the 4 SIT training modes is related to the MPF of lower limb skeletal muscle and the peak torque of knee flexion, but the degree of interpretation is limited. It is independent of Wingate peak/average power and anaerobic power decline rate.
