With the implementation and advancement of national strategies such as“Healthy China”and “Sports Power,” there is an increasing need to enhance the quality of scientific fitness services for the general public. Based on an analysis of the conceptual framework and data relationships of multi-source data-driven intelligent fitness services from the perspective of the integration of sports, medicine, and engineering, this study focuses on key technologies underpinning these services. These technologies include AI-based hazard detection in public sports venues to ensure fitness safety, precise monitoring and intelligent guidance for effective fitness behaviors, technologies for the exchange, integration, and sharing of multi-source heterogeneous fitness data, and privacy protection measures for fitness data.
With the rapid development of artificial intelligence (AI) in recent years, it has already or is poised to implement multiple functions in e-sports, such as assisted training, assisted refereeing, and intelligent broadcasting. However, while AI drives the advancement of e-sports, it also faces corresponding risks of data pollution. For instance, useless player data may reduce the effectiveness of Character AI, outdated match data may compromise the timeliness of intelligent broadcasting, and fabricated officiating data may undermine the fairness of AI refereeing. To address these risks, the primary response strategy is to establish data governance rules in the form of laws and policies.. This involves establishing mechanisms such as the regulation of annotation types, data screening rules, and pre-set standard controls during three stages: data structuring, data screening, and the establishment of the data governance system. These measures ensure the usability and generalizability of collected e-sports data, extract data subsets that meet specific conditions, and ultimately achieve comprehensive prevention of data pollution risks through e-sports data governance rules.
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.
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 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.
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.
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.
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.
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.
Sports consumption is an important engine for expanding domestic demand and smoothing the domestic circulation of the national economy. This paper analyzes China's sports consumption pilot policy, selects panel data from 290 prefecture-level cities in China from 2014 to 2022, and uses the difference-in-differences model to analyze the impact of Chins's sports consumption pilot policy on urban socio-economic resilience as well as the transmission mechanism. From the research results, it was found that: 1) the sports consumption pilot policy has enhanced the urban social and economic resilience, and this conclusion still holds true after parallel trend testing, placebo testing, and PSM testing; 2) The mechanism test results show that the strengthening of urban social and economic resilience through the national sports consumption pilot policy mainly relies on the optimization effect of industrial structure and employment effect; 3) The heterogeneity test results indicate that different cities exhibit diverse characteristics when implementing the sports consumption pilot policy, and the effect of pilot policys on improving urban social andeconomic resilience is more pronounced in large-scale cities and eastern regions. It is recommended to continue implementing the pilot policy for sports consumption cities, fully leveraging the mediating effects of industrial structure optimization and employment effects, and paying attention to the regional heterogeneity of the sports consumption pilot policy in enhancing urban social andeconomic resilience.
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.
