Gender equality is a key measure of social progress and an important goal for human beings to achieve sustainable development. With the implementation of“Transforming Our World - 2030 Agenda for Sustainable Development”, the value of sport for the sustainable development of gender equality has been emphasized, and it has triggered a worldwide change in the concept of sport. Using the literature research method to explore the relationship between sport and the sustainable development of gender equality, we analyze the evolution of the United Nations’consensus on the promotion of sport for the sustainable development of gender equality and the impact it has had in the international community. The expected effects of the UN consensus on sport for the sustainable development of gender equality are summarized in three aspects: improving the physical fitness level of gender-disadvantaged people, promoting the popularization of the concept of gender equality in school physical education, and empowering women’s development. The analysis concludes that the implications for China are: 1) to emphasize the functional value of sport in promoting the sustainable development of gender equality; 2) to establish a basic guideline for the sustainable development of gender equality through sport; 3) to improve the legal system for the sustainable development of gender equality through sport; 4) to further create a cultural atmosphere for the promotion of gender equality through sport.

The logic of the construction of a leading country in sports has important theoretical and practical values for understanding and building a leading country in sports. The study holds that Chinese modernization is the road confidence and road consciousness of building a leading country in sports. The construction of a leading country in sports is the historical inevitable choice of sports development led by the Communist Party of China, hidden in the “sports serving the country, sports rejuvenating the country and sports making the country powerful” of Chinese sports development. The theoretical logic of the construction of China’s modern sports power is to implement the new development concept; the practical logic is to meet the growing demand for sports among the general public in our country; the economic logic is to realize high-quality development of the sports industry; the cultural logic is to Integrate into the sports culture of the Chinese nation ; the technological logic is to provide new impetus for the construction of a sports power.It is necessary to systematically and dialectically understand and grasp the logic of the “Five in One”, and coordinate the promotion in order to build a leading country in sports.

Objective:To explore the influence of exercise intensities and different task difficulties on the image recognition and decision-making of orienteering athletes with different levels. Method: Adopting 2 (exercise level: expert, novice) ×2 (exercise intensities:resting-state,high intensity) ×2 (exercise difficulties:simple map,complex map). In the three-factor mixed experimental design, near-infrared functional imaging (fNIRS) was used to measure the concentration of Oxy-Hb in prefrontal cortex (PFC) of oriented-athletes during the mapping decision task. Results: 1) The accuracy of image recognition decision decreased significantly with the increase of task difficulty and exercise intensity; the expert group was significantly higher than the novice group, and the resting-state group was significantly higher than the high-intensity group. 2) Oxy-Hb activation in left dorsolateral prefrontal lobe (L-DLPFC) and left ventrolateral prefrontal lobe (L-VLPFC) showed group differences, and the expert group was significantly lower than the novice group. With the exceptionof the left frontal polar region (L-FOA), Oxy-Hb activation in the remaining brain regions was affected by exercise intensity, showing a high intensity significantly lower than the resting state. With the change of task difficulty, Oxy-Hb activation in the left dorsolateral prefrontal lobe (L-DLPFC) was enhanced, which was significantly greater than that in simple maps under complex map conditions. 3)In the resting state of a complex map, the blood oxygen activation level of L-DLPFC is significantly positively correlated with accuracy in the expert group. In the resting state of a simple map, the blood oxygen activation levels of L-DLPFC and R-VLPFC are both significantly positively correlated with accuracy in the novice group.Conclusion: The map-reading decision-making task in orienteering is constrained by the intensity of exercise and the difficulty of the task. Expert athletes have certain cognitive advantages, demonstrating higher task performance and lower blood oxygen activation in relevant brain regions of the prefrontal cortex. Task difficulty results in specific activation of L-DLPFC, and the brain’s blood oxygen activation pattern also changes under high intensity.This research is of great significance for optimizing athletes’training strategies, improving competitive performance, and promoting the development of cognitive decision-making in sports.

Using a scoping review within the behavioral epidemiology framework and employing deductive content analysis, this study categorizes and summarizes physical activity in elderly individuals with mild cognitive impairment (MCI) to comprehensively grasp research progress in the relevant field. A scoping review of 59 targeted articles reveals that although few studies have determined the dose-response relationship of physical activity for elderly individuals with MCI, there is sufficient evidence to indicate that moderate-to-vigorous physical activity can improve both physical and mental health. Additionally, traditional sports activities in China have shown promising intervention effects.The use of wearable devices and sensor technology can promote physical activity behavior, and provide objective, convenient, effective, and diverse data analysis results for measuring physical activity in elderly individuals with MCI. Through in-depth analysis of the common characteristics of physical activity, early neurodegenerative diseases can be screened. Intrinsic motivation, influenced by individual, behavioraland environmental factors, is key for elderly individuals with MCI to engage in physical activity, with family support being crucial for sustained participation.Furthermore, exploring the influencing factors of physical activity based on theoretical frameworks can make the enhancement of physical activity levels and the formulation of intervention programs more persuasive. Interventions that are designed, implemented, and evaluated based on family environment, supported by social backing, and guided by theoretical frameworks can more scientifically alter the physical activity behavior of elderly individuals with MCI.

The home address is the primary site for the governance of adolescents' out-of-school physical activity, and family factors are intricate and complex. To clarify the family factors of adolescents' out-of-school physical activity, the composition of family factors affecting adolescents' out-of-school physical activity and their interrelationships were analyzed by using qualitative research methods to explore the influencing mechanisms. A model of family factors influencing adolescents' out-of-school physical activity was constructed through exploratory analysis, deduction, and refinement of key journal literature related to adolescents' out-of-school physical activity and interview data from 46 respondents using grounded theory. Family factors were found to include parental cognitive transformation, family empowerment, family sport culture, family environment, and family sociodemographic characteristics. Factors of parental cognitive transformation are the internal driving force of youth out-of-school physical activity. Factors of family empowerment factors and socio-demographic characteristics are the foundation and support of youth out-of-school physical activity.Family sport culture and family environment are repectively motivational and mediating facors of youth out-of-school physical activity, respectively. Based on this, the governance framework of family influencing factors of youth out-of-school physical activities is deduced: family empowerment, as the foundation and support, vertically integrates and horizontally coordinates other factors, and through the core effect of factors of social demographic characteristics among other factors, to form a healthy and harmonious family environment and family sport culture suitable for youth out-of-school physical activities, and through the cognitive transformation of parents to form a healthy and harmonious family environment and family sport culture. The improvement of youth out-of-school physical activities will be ultimately achieved.

This article uses literature review, following the research approach of discussing governance values, analyzing governance status, identifying governance dilemmas, and proposing practical and feasible strategies for China’s response. After analysis, it is believed that the current global public domain sports governance is facing challenges such as the imbalance of governance power caused by the change of subjects, the dominance of Western powers in the governance agenda, the lack of consensus on global sports governance rules and norms, and the exacerbation of anti-globalization in sports governance due to the dominance of populist ideology. Therefore, it’s proposed that 1) China should take the development of all mankind as the concept, build collaborative relationships among diverse governance entities. 2) China should strengthen the hard power of mainstream sports around the world and elevate the discourse power of global public domain sports governance. 3)China should improve governance organizational structures, promote the reform of the global public sports governance system. 4)China should vigorously cultivate international talents, and build a reserve team of international sports organizations.

The theoretical logic of integrating sports and education talents to promote rural revitalization lies in enhancing the level of public sports services in rural areas, boosting the development of rural sports industries, and revitalizing rural sports culture. There are practical difficulties such as insufficient overall planning of physical education talent training programs, insufficient efforts to help the development of rural sports industry, poor channels for college students majoring in physical education to help the revitalization of rural physical education, and the urgent need to give full play to the revitalization of rural physical education and training through sports resources of the school-running platform. Based on the difficulties, the following practical approaches are proposed: 1) to deeply coordinate and implement the training program for physical education professionals to help rural revitalization; 2）to integrate the inheritance talent resources of sports intangible cultural heritage to help rural sports revitalization; 3) to organize“double-teacher” physical education teachers to go deep into rural areas to carry out volunteer service and practical teaching and research activities;4) to organize students majoring in physical education to carry out voluntary service activities combining physical education teaching and physical education service in rural areas; 5) to open a diversified physical education teaching practice base in the school.

Physical Education and Health course has been the focus of attention in recent years. The Eighth National Survey on Student Physical Fitness and Health reported that students still have problems such as high myopia rates and rising rates of overweight and obesity. Physical education class is a main frontier for students and its impact on self-rated health has not been fully studied. Based on the survey data on children’s sports activity participation and sports needs in the Beijing-Tianjin-Hebei region, a sequential logistic model was used to explore the impact of physical education classes on primary and secondary school students’self-evaluated health and analyzes the regulatory mechanism of sports awareness through interaction terms. Based on the survey data of children’s participation in sports activities and sports needs in the Beijing Tianjin Hebei region, this study uses a sequential logistic model to explore the impact of physical education classes on self-rated health of primary and secondary school students, and analyzes the regulatory mechanism of sports awareness through interaction terms. The study found that: the number of physical education classes per week, the attitude of participating in physical education classes, and the tendency to practice independently after physical education classes have significant positive impacts on the increasing self-evaluated health; sports identity also has a significant positive impact on self-rated health, and alleviates the attitude of participating in physical education classes, “crowding” or “not attending”physical education classes, and the widening effect of circumstances on self-rated health disparities. In the future, we can improve the self-evaluated health of primary and secondary school students and enhance the talent support for building sports power by increasing the number of physical education classes, promoting students’tendency to practice independently after physical education classes, improving the quality of physical education teaching, and cultivating sports interest and identity.

This study employs literature review, and logical reasoning to examine the opportunities, realistic difficulties, and pathways for Chinese Wushu“Going Global” in the new development stage. Grounded in communication studies, cultural theory, and sociological frameworks, the research identifies that while benefiting from“Going Global”, the national strategic support, the Belt and Road Initiative, andthe era of media convergence, Chinese Wushu faces challenges including the complex and ever-changing media communication environment, the lack of classification of audience demands, superficial and single content, uncoordinated media channels, and chaotic communication practices. Proposed solutions involve: eliminating barriers to international sports collaboration, and creating an effective media communication ecosystem;segmenting audiences of media,and preciselty disseminating the culture of Chinese martial arts; selecting the content of media communication accurately according to the needs of audiences; jointly promoting Chinese martial arts to“Going Global”, and coordinating the main bodies of the dissemination of martial arts culture; establishing evaluation mechanisms, and continuously innovating dissemination methods to enhance global cultural influence.

Objective: To systematically evaluate the intervention effect and optimal dose of different exercise methods on myopia in children and adolescents. Methods: 32 studies (n=8 804) were included by searching PubMed, Web of Science and other databases, and network meta-analysis was performed using RevMan5.3 and Stata16.0. Results: 1) Effects on visual acuity improvement: the static visual acuity was best in outdoor sports (98.7%), followed by dancing (53.2%), sports games (41.2%), ball games (25.0%) and combined intervention (6.5%). Ball games (85.5%) and outdoor sports (85.4%) had similar effects on improvement of dynamic visual acuity. Outdoor sports (81.0%) were superior to ball games (72.6%) in terms of ocular axis regulation. 2) Dose effect: The lowest effective dose was 2~3 times per week[SMD=0.23,95%CI(0.15,0.30)], single 30 to 40 minutes per session[SMD=0.01,95%CI(0.08,0.10)], and lasted for 6~12 weeks[SMD=0.04,95%CI(0.03,0.11)]; Best sports dose was for 6~7 times a week[SMD=0.56, 95%CI(0.33,0.78)], 41~60 minutes per session[SMD=0.26,95%CI(0.21,0.32)], and lasted for 21~36 weeks[SMD=0.40,95%CI(0.24,0.56)]. Conclusion: Dancing, sports games, ball games, outdoor sports and combined intervention can effectively improve the myopia of children and adolescents, among which outdoor sports and ball games have the best effects. It is recommended that children and adolescents give priority to these two types of exercise, carry out exercise at least 2~3 times a week, 30 to 40 minutes each time, and last for 6 to 12 weeks; Increasing the duration or frequency according to individual situations can further enhance the effect of myopia improvement.

Insufficient physical activity among children and adolescents has become a global challenge. Many researchers have adopted the self-determination theory(SDT) as a theoretical framework to promote physical activity in this population. It is suggested that providing need-supportive strategies(e.g., autonomy support) during physical education classes, school-based extracurricular activities, and leisure time outside school can enhance children and adolescents'positive physical activity experience, with different primary supporters identified across these contexts. Furthermore, autonomy support (need support) provided by physical education teachers in class may influence children and adolescents'leisure-time physical activity through the mediation of autonomous motivation for physical activity, with the trans-contextual model (TCM) potentially explaining this cross-contextual mechanism. Recommendations include: 1) Refining need-supportive strategies across contexts based on SDT; 2) Fully considering gender differences in future research; 3) Further exploring mechanisms and key variables that promote physical activity among children and adolescents in different settings.

Using the 2020 microdata from the China Family Tracking Survey (CFPS), we empirically analyze the impact of digital literacy on the participation of middle-aged and elderly people in physical exercise and its mechanism at the household level. It is found that the improvement of digital literacy can promote the participation of middle-aged and elderly people in physical exercise, and the conclusion still holds after conducting robustness tests and addressing endogeneity issues by replacing the estimation method and replacing the core explanatory variables. Heterogeneity analysis shows that digital literacy has different degrees of significant effects on middle-aged and elderly people's participation in physical exercise, as follows: more obvious in the eastern region than in the central and western regions, more obvious in the middle-aged group than in the elderly group, more obvious in males than in females, and more obvious among those with a secondary school education than among those with a elementary school education or below and those with a university education or above. The mechanism test found that digital literacy can promote family income and subjective well-being indirectly influence middle-aged and elderly people's participation in physical exercise. Accordingly, the following recommendations are made: strengthening education and training on digital literacy for residents to encourage middle-aged and elderly people to actively participate; creating an age-friendly digital ecosystem to optimize digital sports resources and services; improving digital sports infrastructure; and organizing and carrying out digital sports activities.

Promoting the digital construction of national fitness venues and facilities is a crucial component in building a higher-level public service system for national fitness. Assessing the degree of digital construction of fitness facilities has become a central means to improve the quality of public services for national fitness. Using research methods such as literature review and case analysis, and on the basis of explaining the conceptual connotation of the digitalization of fitness facilities and the significance of evaluating the digitalization of fitness facilities, this study first draws on the structural elements and classification levels of digital transformation maturity assessment models. Taking county seats as the focal point, it constructs a digital maturity assessment model for fitness facilities with digital readiness, digital practice, and digital performance-and incorporates 7 key process areas, 15 sub-key domains, and 4 digital maturity levels. An empirical case analysis is conducted to validate the model, aiming to provide methodological and practical tools for addressing the challenges in evaluating the digital construction of national fitness initiatives.

Sports events and media have always been inseparable, and the media not only gradually shape the basic appearance of sports with its their own influence, but also quietly change the basic ways in which people participate in sports. Based on the theories of media evolution and body phenomenology, and field theory the research was conducted and was considered that: the sports lifestyle and sports activities have undergone a synchronous evolution process of virtualization, mediaization and virtualization.Sports activities have been gradually distinguished into experiential practice and inscribed practice in this process.The two practices are located in the field of sports and field of communication respectively. The difference between the“subjective body” view in the field of sports and the“instrumental body”view in the field of communication, led to the resource competition between the two fields about time and space, interpersonal relationships and body. “The unity of Tao and Qi”is a new path to achieve the deep of fields and resource sharing, and to balance sports and daily life based on meida digital iteration.

Clavicle fractures are common among cyclists and are associated with prolonged recovery times. This study explores a rehabilitation training method based on the principles of progression and comprehensiveness, aiming to prevent disuse atrophy in non-injured areas while ensuring safe recovery of the injured site, to provide a reference for cyclists to return to competition safely and as early as possible. A 19-year-old national team cyclist, specializing in short-distance track cycling, sustained a mid-third clavicle fracture after a fall during training, with a pain score of 9/10 on the Numerical Pain Rating Scale (NPRS). The athlete underwent open reduction and internal fixation surgery 3 days post-injury. The rehabilitation training lasted for 4 weeks and included shoulder joint function training, aerobic exercise, strength training, core stability training, and sport-specific training, progressing from functional reconstruction to physical fitness recovery and then to sport-specific performance recovery. The primary outcome measures were pain level (NPRS), upper limb, shoulder, and hand function score (DASH), and Constant-Murley score. Secondary outcomes included time to return to competition, sports performance, and kinesiophobia (TSK). At 4 weeks post-surgery, the NPRS score decreased from 7 to 0, the DASH score decreased from 30 to 4.2, the Constant-Murley score increased from 26 to 79, and the TSK score decreased from 39 to 33, all exceeding the minimal clinically important difference (MCID). Follow-up at 4 weeks showed further improvement with NPRS at 0, DASH at 0, Constant-Murley score at 100, and TSK at 25, which remained stable at 1-year follow-up. The athlete returned to national track cycling competitions after 4 weeks and achieved excellent results. Conclusion：A rehabilitation training method focused on preventing disuse atrophy in non-injured areas and ensuring safe recovery of the injured site can effectively promote the recovery of cyclists with clavicle fractures, enabling them to return to competition safely in the shortest possible time.

Objective:To explore the impact of physical activity on the relapse tendency of maleindividuals in compulsory drug rehabilitation and examine the chain mediating effects of self-acceptance and psychological distress. The goal is to provide a reference for developing rehabilitation training programs during compulsory drug detoxification for substance abusers. Methods: A questionnaire survey was conducted among 395 maleindividuals undergoing compulsory drug rehabilitation using the Physical Activity Scale-3 (PAS-3), Self-Acceptance Questionnaire (SAQ), Symptom Checklist-90 (SCL-90), and Relapse Tendency Questionnaire. The collected data were statistically analyzed. Results:1) In the chain mediation model, the total predictive effect of physical activity on relapse tendency was -0.234, with a direct predictive effect of -0.113 and a total indirect effect of -0.120, all of which were statistically significant. 2) The indirect effect of physical activity on relapse tendency was mediated by self-acceptance (effect value -0.053; effectproportion 22.80%), psychological distress (effectvalue -0.048; effectproportion 20.70%), and the chain mediating effect of self-acceptance and psychological distress (effect value -0.019; effectproportion8.00%).Conclusion:Physical activity can directly influence the relapse tendency of male drug rehabilitation participants and can also affect relapse tendency through the mediating role of self-acceptance or psychological distress. Additionally, it can influence relapse tendency via the indirect path of the self-acceptance-psychological distress chain mediation effect.

Objective:The effects of different message-framed interventions on college students' exercise intentions and behaviors were explored through two sub-experiments, a single and a long-term intervention. Methods:Experiment 1 selected 102 college students and used a 4 (information frames: positive, negative, joint, control) × 2 (preference of information attention: positive, negative) between-subjects design to assess changes in exercise intentions before and after the information intervention. Experiment 2 selected 52 university students and used a 2 (group: information intervention, control) × 5 (intervention period: baseline, 6 weeks, 8 weeks, 10 weeks and 12 weeks) mixed experimental design to clarify the quantitative and qualitative relationships between intervention period and exercise behaviors. Results:A single exercise-related information intervention enhanced college students'exercise intentions, and the positive and negative combined information interventions were the most effective, preference of information attention failed to modulate the effect of the information intervention on exercise intentions, and perceptions of exercise risk partially mediated the relationship between the information intervention and exercise intentions. The long-term joint information intervention had a significant improvement effect on the amount of exercise behaviors of college students, and the 6-week intervention had been able to achieve the optimal effect. Conclusion: Positive and negative jointed information can be preferred for the information intervention on exercise intentions and behaviors, and at the same time, moderately improving the level of perceptions exercise risk among college students also has a better predictive effect on their exercise intentions. In the selection of the cycle dose of jointed information intervention, three times a week for six weeks can better promote the exercise behaviors of college students.

The scientific setting and standardized application of morality clauses in the field of professional sports provide institutional guarantees for promoting the healthy development of professional sports. By using literature research and comparative analysis methods, the evolution and existing problems of the application of morality clauses in professional sports outside the territory were systematically sorted out. After analysis, it is believed that extraterritorial countries such as the United States, United Kingdom, and Germany have introduced morality clauses to effectively exercise their functions of behavioral regulation, risk allocation, and damage remediation, thereby preventing and regulating athletes'moral anomie behavior. However, with the expanding application scope of morality clauses, their implementing parties have become increasingly diversified, regulatory content continues to broaden, and clauses formulations grow progressively ambiguous. While achieving notable results, these developments have concurrently revealed systemic issues including disproportionate sanctions, ambiguous definitions of immorality and inadequate information protection. Based on this, it is suggested that China should play the role of different entities in promoting and supervising the application of morality clauses, clarify the behavioral boundaries regulated by morality clauses, refine sanction standards, while concurrently introducing reverse-morals clauses and clawback provisions. These multidimensional approach aims to achieve an equitable balance between maintaining sporting ethics and protecting athletes'rights.
