A206: Equity in Physical Education for Disadvantaged Groups: The Twin Dilemmas of Policy and Culture
No full textBased on the Healthy China 2030 and Education Equity Strategy, physical education for disadvantaged groups faces both institutional and cultural constraints. This study reveals that the interaction between policy blindness and cultural exclusion leads to resource imbalance and opportunity deprivation. Based on Sen\u27s theory of equality of ability and Bourdieu\u27s theory of cultural capital, the study systematically deconstruct the neglect of group differences in policy design and the implicit exclusion mechanism in social concepts (e.g. The study attempted to fill the gap between the ‘disability = low motor ability’ stereotype in the existing literature and the ‘disability = low motor ability’ stereotype in the social concepts.) The study attempts to fill the gap of ‘institutional-cultural’ analysis in the existing literature and to help achieve the goal of inclusive physical education. This paper adopts a mixed research method, consisting of policy text analysis (central and local policies from 2015-2023) and fieldwork (20 in-depth interviews, 10 hours of participant observation, and case profiling). 1) Insufficient institutional coverage and implementation bias. Analysis of policy texts shows that only 12 percent of central-level physical education policies for 2015-2023 explicitly mention that adapted physical education programs are not mandatory for disadvantaged groups such as students with disabilities and migrant children, and 73 percent of local supporting policies lack actionable details on resource allocation. 2) Conceptualization and behavioral discrimination. In-depth interviews revealed that 67% of teachers believe that ‘students with disabilities are at risk of participating in regular sports activities’, and thus tacitly allow them to ‘stand by’ or only arrange low-intensity activities, and that migrant children are implicitly excluded from group programs. As a result, migrant children were implicitly excluded from group programs, and the probability of migrant children being selected for core roles was less than 10 percent. 3) The reciprocal reinforcing effect of the double dilemma: policy neglect leads to teacher incompetence, further entrenching the prejudice that ‘disability = low motor ability’; and cultural exclusion, in turn, weakens the impetus for policy implementation. Physical education for disadvantaged groups is constrained by both policy blindness (insufficient coverage and lack of implementation) and cultural exclusion (discrimination against disabled and migrant children) and requires concerted reform and AI empowerment to support the goals of Healthy China and UNESCO and to guard against implementation bias
A277: Nanchang’s Adolescents Community Sports Under the Double Reduction Policy: Current Situation and Countermeasures
No full textRecently, the Double Reduction policy has been introduced by the Central Committee of the Communist Party of China and the State Council. It has not only provided strong policy support for the promotion of sports and health for the whole society but also provided a safety net for the healthy development of children and adolescents. To some extent, it has curbed the continuous decline in the physical health of adolescents in China. However, the biggest weakness in the healthy growth of adolescents lies in the community， where there is often a lack of sufficient sports facilities and organized activities. Therefore, there is an urgent need to conduct in-depth research to improve the community support system and promote the comprehensive development of adolescents. Based on this, through methods such as literature review, questionnaire survey, interview, and mathematical statistics, we conducted a survey and analysis on the current situation of adolescents’ sports participation in 51 communities in Xinjian District, Wanli District, Honggutan District, and other areas of Nanchang. The results show that the Double Reduction policy has provided more opportunities and time for adolescents to participate in community activities, and their participation in sports activities has increased significantly. The demand for community sports projects among young people is diverse, but badminton is particularly popular. The difficulties faced by adolescents in participating in community sports mainly include social and time barriers, a mismatch between sports resources supply and demand, and conflicts in time and space, as well as insufficient innovation in smart community sports. Conclusions/Discussions: The “Double Reduction” policy has increased adolescents’ opportunities and time for community sports, with badminton being particularly popular. However, participation is still hindered by social and time barriers, resource mismatches, spatiotemporal conflicts, and insufficient innovation in intelligent community sports. Countermeasures: The participation of adolescents in community sports in Nanchang has shifted from facility-driven to demand-driven . Breakthroughs are needed in three dimensions: precise supply of team sports projects, adolescent-friendly community sports transformation, and upgrading of smart community sports. Only in this way can we achieve a leap from quantitative participation to qualitative health improvement in community sports for adolescents
A218: Efficacy of Kinesio Tape for Plantar Fasciitis: A Systematic Review and Meta-Analysis
No full textPlantar fasciitis is one of the most common causes of heel pain in adults and is a very common musculoskeletal system disorder. The incidence of plantar fasciitis is relatively high among sports enthusiasts, especially those involved in high-intensity, high-impact sports. Kinesio tape has the functions of relieving pain, correcting muscle function, and increasing body sensation. Currently, kinesio tape has been gradually applied to the treatment of the disease, but its effectiveness is unclear. The aim of this review is to assess how kinesio tape interventions affect pain and ankle and foot function in patients with plantar fasciitis. PubMed, Scopus, Web of Science, Cochrane Library, Embase, Ebsco, Sinomed, CNKI, WangFang, VIP, and ClinicalTrials.gov were consulted from inception to April 2024, with the inclusion of randomized controlled trials. The experimental data were meta-analyzed using RevMan 5.3. The outcomes include pain and function of the ankles and feet. Result: The meta-analysis included seven studies of a total of 356 p. Results showed significant differences in kinesio tape performance in pain improvement (SMD = -0.90, 95% CI: -1.49, -0.31, P = .003) and in ankles and foot function improvement (SMD = 0.74, 95% CI: 0.48, 0.99, P \u3c .001) in patients with plantar fasciitis compared to the control group. For patients with plantar fasciitis, kinesio tape treatment is an effective method. It has significant advantages in reducing pain and improving ankle and foot function
A066: Aerobic Exercise Regulates miR3473e/EphB2 Signal Pathway in Improving Synaptic Plasticity in APP/PS1 Mice
No full textAlzheimer\u27s disease (AD) is a neurodegenerative disease characterized by cognitive impairment, with evidence suggesting that exercise can improve cognitive function. Our previous studies demonstrated that aerobic exercise improves cognitive dysfunction and enhances synaptic plasticity in APP/PS1 mice, while identifying the endogenous microRNA-3473e as a potential regulator of neuronal activity and cognitive function. However, the precise mechanism underlying this regulation remains unclear. This study aimed to investigate the mechanism by which aerobic exercise regulates miR3473e to improve synaptic plasticity and cognitive dysfunction in APP/PS1 mice. Exercise intervention was performed on 3-month-old C57BL/6J and APP/PS1 mice with a 12-week moderate-intensity aerobic treadmill training program. The Morris water maze test was employed to assess learning and memory capabilities. Golgi staining was used to evaluate dendritic spine density. Transcriptomic profiling was performed using RNA sequencing (RNA-Seq), followed by bioinformatics analysis and target gene screening. Quantitative reverse transcription PCR (qRT-PCR) was utilized to validate the expression levels of miR-3473e and its downstream targets EphB2 and Slc1a1, as well as synaptic plasticity-related genes CREB, SYN, and PSD95. Western blotting was conducted to examine the protein expression levels of EphB2, PSD95, GluN1, GRIA1, GluN2B, and p-GluN2B. 1) Morris water maze tests revealed that 12 weeks of moderate-intensity aerobic exercise significantly enhanced learning and memory in APP/PS1 mice. 2) Aerobic exercise increased dendritic spine density in the cortex and hippocampus of APP/PS1 mice, accompanied by elevated expression of synaptic plasticity-related genes CREB, SYN, and PSD95. 3) Transcriptomic analysis identified miR-3473e as a candidate target, which was found to be overexpressed in the brains of APP/PS1 mice. Notably, miR-3473e expression was significantly downregulated in aerobic exercise. 4) Aerobic exercise upregulated the expression of miR-3473e downstream targets EphB2 and Slc1a1 in APP/PS1 mice. Furthermore, exercise increased the protein levels of NMDA receptor subunits GluN1 and GluN2B, as well as their phosphorylation (p-GluN2B), and the AMPA receptor subunit GRIA1 in APP/PS1 mice. Conclusion: 1) Aerobic exercise increased dendritic spine density in the cortex and hippocampus of APP/PS1 mice, thereby enhancing synaptic plasticity and ameliorating cognitive deficits. 2) The cognitive and synaptic improvements in APP/PS1 mice following aerobic exercise were mediated through the miR-3473e/EphB2 signaling pathway
A274: Baduanjin for Rehabilitation in Stable-Stage COPD: A Review of Recent Research
No full textChronic obstructive pulmonary disease (COPD) significantly impairs patients\u27 quality of life. Recently, the traditional Chinese exercise Baduanjin has garnered attention for its potential benefits in the rehabilitation of patients during the stable phase of COPD. This study aims to review and analyze existing research on the application of Baduanjin in COPD rehabilitation to provide insights for clinical practice. Method: A comprehensive literature search was conducted in databases such as CNKI, Wanfang, and PubMed to collect studies published in recent years focusing on Baduanjin and COPD stable phase rehabilitation. The collected studies were systematically reviewed and analyzed to summarize the therapeutic effects and current research status of Baduanjin in COPD rehabilitation. The analysis indicates that Baduanjin practice can: 1. Enhance exercise endurance and improve pulmonary function parameters such as FEV1/FVC. 2. Improve blood gas levels, evidenced by increased oxygen partial pressure and decreased carbon dioxide partial pressure. 3. Alleviate airway inflammation by effectively regulating sputum inflammatory markers, including IL-8, TNF-α, CRP, and neutrophils. 4. Alleviate clinical symptoms, as demonstrated by improvements in the 6-minute walk test, modified dyspnea index, and COPD assessment test scores. 5. Enhance quality of life by reducing limitations related to coughing, sputum production, and restricted activities, as reflected in scores from the St. George\u27s Respiratory Questionnaire (SGRQ) and the WHO Quality of Life-BREF (WHOQOL-BREF). 6. Ameliorate psychological states, with long-term Baduanjin practice alleviating anxiety and depression. 7. Notably, short-term interventions (≤ 3 months) improve exercise endurance, but their effect on pulmonary function requires further validation. Long-term interventions (\u3e 3 months) yield more significant benefits. Baduanjin appears to positively influence pulmonary ventilation, blood gas parameters, inflammatory responses, clinical symptoms, quality of life, and psychological well-being in patients with stable-phase COPD, with prolonged practice yielding superior outcomes. However, existing studies often suffer from methodological limitations such as small sample sizes, short intervention durations, and simplistic statistical analyses. Future research should focus on large-scale, well-designed clinical trials and mechanistic studies to further elucidate the efficacy of Baduanjin in COPD rehabilitation
A136: A Literature Review on the Impact of Smart PE Classrooms on College Students
No full textAs digitalization, networking, and intelligent technologies continue to advance, “smart classrooms” have emerged as an innovative teaching model. In many traditional college physical education (PE) courses, instructors often employ a “one-size-fits-all” approach that can stifle some students’ enthusiasm and motivation. By introducing smart devices and digital platforms, smart classrooms aim to offer more personalized and interactive learning experiences. However, given the unique requirements of PE courses and the practical constraints within universities, the adoption of smart classrooms remains limited. To address this gap, the present review summarizes existing literature on the impact of smart PE classroom teaching models on college students. Method: Using keywords such as “smart physical education classrooms,” “student exercise participation,” and “sports skills”, we conducted a literature search in databases such as Web of Science and China National Knowledge Infrastructure. The inclusion criteria are： (1) took place in a college-level PE setting; (2) employed smart devices and data platforms (e.g., wearable fitness trackers or smart teaching platforms) during the intervention; (3) primarily evaluated the influence of this teaching model on students’ exercise participation and skill acquisition. Result: A total of five articles were included. All studies employed a controlled design comparing a smart PE classroom to a traditional classroom over a 16-week period (in accordance with national requirements, undergraduate students in their first and second years must enroll in PE courses each semester for four semesters, totaling 144 hours). Participants were first- and second-year college students, with sample sizes ranging from 60 to 80. Findings indicated that, compared with traditional teaching methods, smart PE classrooms significantly increased students’ exercise participation and improved their sports skills (p \u3c 0.05). Current evidence suggests that the smart PE classroom teaching model has a positive impact on students’ sports performance and learning engagement. Nevertheless, the limited sample sizes and relatively short intervention periods restrict the external validity of these findings. Furthermore, implementing a smart PE classroom can involve substantial investment in devices and platform infrastructure, posing challenges for long-term sustainability. Future studies should consider larger samples and extended intervention durations to more comprehensively assess the long-term effects and feasibility of smart PE classrooms. Researchers should also explore strategies to effectively integrate smart technologies with traditional PE instruction, thereby leveraging the strengths of both approaches to enhance teaching quality
A182: Study on the Transnational Flow of Chinese Elite Table Tennis Players and Its Influencing Factors
No full textThis study aims to explore the historical context and current situation of the transnational flow of Chinese elite table tennis players. By applying the push-pull theory, it analyzes both structural and non-structural factors influencing this phenomenon, providing valuable insights for understanding the dynamics of transnational mobility among Chinese elite table tennis players. The research employs literature review and interview methods to trace the historical trajectory of transnational flow among Chinese table tennis players and addresses two key questions: Why do they choose to move abroad? and How do they integrate into foreign environments? 1) The transnational flow of Chinese elite table tennis players can be categorized into three distinct phases. Phase one (1966-1992) was characterized by state-sponsored overseas assignments with individual initiatives as a secondary factor. Phase two (1988-1995) saw retired national team members seeking opportunities abroad, which sparked considerable controversy. Phase three (1996-present) has witnessed an increasing trend of table tennis talents proactively seeking international development opportunities. 3) Factors influencing the transnational flow include the attractiveness of foreign table tennis environments and the intense competition within China\u27s domestic scene. Firstly, the earlier establishment and mature development of foreign professional table tennis leagues provide viable career continuation opportunities for Chinese elite players. Secondly, China\u27s competitive level and rapid talent turnover limit participation opportunities in international competitions for many talented players. Thirdly, the aspiration of elite table tennis players to participate in prestigious international competitions such as the Olympic Games, World Championships, and World Cup, coupled with their desire to realize personal value, motivates them to change their nationality to secure eligibility. Finally, the limitations imposed by the Olympic Games on the number of participants per National Olympic Committee, as well as the restrictions set by the World Championships and World Cup on the number of participants per national table tennis association, significantly reduce opportunities for many talented players
A222: Transformational Leadership and Tacit Knowledge Transfer in Sports Events
No full textThe successful staging of international sports events in China heavily relies on the contributions of numerous short-term paid professionals across various functional departments. However, research on knowledge transfer among these professionals within organizing committees remains scarce. This study aims to address this research gap. Grounded in Social Exchange Theory, it investigates how transformational leadership within organizing committees promotes team trust, thereby fully exploiting and applying the tacit knowledge of these professionals to achieve effective knowledge retention and transfer. Method: This study employs semi-structured interviews to collect data from 20 professionals who have participated in continental or global sport events. NVivo software was used for data coding and theme extraction. Result: The results reveal that leaders\u27 professional competence, benevolence, and organizational procedural justice, as well as professionals\u27 trust propensity, play a crucial role in facilitating knowledge sharing and transfer. Organizing committees should select managers with extensive event management experience, fulfill reward commitments in accordance with the contractual spirit, and provide further career development platforms and opportunities for professionals. This study offers theoretical and practical insights for the operation of international sports events
A133: Self-Aggrandizing in Badminton Teaching Short Videos Affects Learning Willingness
No full textBased on the new era of digital sports development, self-media platforms have become an important carrier of sports teaching communication; however, few studies have investigated the relationship between self-aggrandizing behavior during sports teaching on self-media platforms and platform users\u27 learning intention. In this study, we take Jittery self-media platform as an example to explore the chain path that creators\u27 boasting behavior (H1) positively affects users\u27 learning intention (H2) by enhancing users\u27 trust (H3), and to verify the mediating effect of trust in the relationship between boasting behavior and learning intention, as well as the two-way influence between badminton short video creators\u27 boasting behavior and platform users\u27 willingness to learn on self-media platforms. Method: Fifty badminton instructional creators with 10,000-100,000 followers on the Jieyin platform were randomly selected from 200, and their badminton instructional videos published from October to December 2024 were collected. Ext was extracted by speech recognition, and the frequency of self-aggrandizing words (times/minute) was quantified by the LIWC tool. The willingness to learn index was calculated by normalizing the number of likes, comments, and shares. The study design included (1) negative binomial regression to test the inverted U-shaped relationship, (2) SPSS path analysis to test the mediating effect of trust, and (3) hierarchical regression to analyze the heterogeneity of video type (entertainment/competitive) and creator gender. Quantitative analyses revealed (1) a significant inverted U-shaped relationship between self-aggrandizing behavior and willingness to learn (β=0.32 to -0.21, p \u3c 0.05); (2) a 65% trustworthiness mediated effect (Sobel Z=2.76, p=0. 006); and (3) higher self-aggrandizement thresholds for entertaining videos (4.2 times/minute) than for competitive videos (3.7 times/minute), with male creators having stronger negative effects of excessive self-aggrandizement (ΔR²=0.12, p=0.008). This study confirms that moderate self-aggrandizing behaviors of short instructional sports video creators can influence users\u27 trust in self-media platforms and increase willingness to learn, while excessive self-aggrandizing decreases users\u27 willingness to learn. In the future, it can be extended to multi-sports categories, combined with user behavior data, and longitudinal data can be introduced to verify the effect
A203: Challenges and Strategies of Physical Education Teachers in Curriculum Design: Literature Review and Analysis
No full textPhysical education teachers face numerous challenges in curriculum design, including a lack of innovation in course content, insufficient teaching resources, and unmet differentiated student needs. These issues directly impact the quality of physical education and student engagement. This study aims to explore the main challenges encountered by physical education teachers in curriculum design through literature review and data analysis, and to propose corresponding strategies for improvement. This study employs a literature review method, systematically searching for relevant literature related to physical education teachers’ curriculum design over the past five years. Databases used include CNKI, WOS, and Science Direct. The primary search keywords are sports curriculum, sports teaching resources, and physical education teachers. Initially, 1,053 relevant papers are identified, and after screening titles and abstracts, 50 high-quality papers are selected for detailed analysis. The data analysis process involves coding the literature, utilizing NVivo software to extract core themes and subthemes, and ultimately forming an analytical framework. The literature analysis reveal that physical education teachers primarily face three core challenges in curriculum design: First, there is insufficient innovation in course content, leading to dull teaching, with about 70% of the literature mentioning this issue; Second, there is a shortage of teaching resources, especially in rural areas, cited in 60% of the papers; Third, there is a failure to adequately consider differentiated student needs, resulting in insufficient personalized teaching, mentioned in 50% of the literature. Each theme is supported by qualitative data highlighting specific cases and the actual difficulties faced by teachers. The findings of this study are consistent with previous research, indicating that issues such as a lack of course content innovation and insufficient resources are prevalent. However, it further emphasizes the importance of addressing students\u27 personalized needs. Future research should focus on innovative curriculum methods and resource integration. The study’s limitations lie in its concentration on specific areas, suggesting that future studies could expand into other educational contexts. The practical significance is to provide physical education teachers with specific curriculum improvement suggestions aimed at enhancing teaching quality and student learning experiences
