A143: Analysis of Fast-Food Consumption Behavior Among Physically Active Male Students in a Beijing University
No full textThis study aims to analyze the fast-food consumption behavior among physically active college students in a university in Beijing and provide a scientific basis for future nutritional education and intervention strategies targeting this population. A simple random sampling method was used to select 850 undergraduate students from a sports-focused university in Beijing. Data on fast-food consumption were collected through a self-administered questionnaire. The survey assessed the frequency of fast-food consumption, reasons for food choices, and students’ perceptions of nutritional value. A total of 807 valid questionnaires were collected, yielding a response rate of 95.8%. The reported consumption of Western and Chinese fast food was 34.6% and 30.6%, respectively. The primary reasons for consuming Western fast food were good taste (77.1%), advertising (6.5%), attractive packaging (5.4%), peer influence (5.4%), and hygiene (5.0%). In contrast, the main reasons for choosing Chinese fast food were good taste (74.5%), health/nutritional value (25.9%), hygiene (15.4%), peer influence (8.9%), and advertising (7.3%). Additionally, 72.8% of students believed that Western fast food is high in calories, while 46.0% considered Chinese fast food to have a well-balanced nutritional composition. The findings indicate that fast-food consumption is prevalent among physically active college students in Beijing. Despite recognizing the high caloric content of Western fast food, many students lack sufficient nutritional knowledge. There is a need for targeted nutritional education and intervention strategies to enhance awareness and promote healthier eating habits in this population
A043: Effects of Treadmill Exercise on Negative Emotions in Postmenopausal Women
No full textNegative emotions occur across all genders and age groups, but their prevalence is notably higher in women during and after perimenopause. This study aims to analyze the effects of a treadmill-based exercise program on depression, anxiety, and stress in community-dwelling Chinese women. Additionally, it seeks to investigate whether these changes are associated with physical changes, such as improvements in body composition or body satisfaction. Method: A total of 80 postmenopausal women (57.04 ± 5.49 years) were recruited from local communities and participated in this single-blind, controlled trial. Participants were assigned to either a control group (n = 40) or an exercise group (n = 40 completed 8 weeks of moderate-intensity treadmill exercise or received usual care. Negative emotions (the primary outcome) were assessed using the Depression, Anxiety, and Stress Scale-21. Body composition was evaluated using dual-energy X-ray absorptiometry, and body satisfaction was measured using the Body Appreciation Scale-2. Repeated measures ANOVA was used to examine mean differences in negative emotions between the two groups. Pearson correlation was used to explore the relationship between changes in physical parameters and changes in negative emotions. Once a significant correlation is established, mediation analysis will be employed to investigate whether the physical parameters mediate the relationship between the group assignment and changes in negative emotions. After 8 weeks, the exercise group showed a significant improvement in negative emotions (mean difference = −1.775 points, 95% CI [−0.513, −3.037], p = 0.006) compared to the control group (group × time interaction, F(1,78) = 4.976, p = 0.029, η² = 0.060). Specifically, exercise significantly reduced anxiety (p = 0.009), tended to improve depression (p = 0.057), but had no significant effect on stress (p = 0.216). The reduction in negative emotions was associated with improvements in body fat (r = 0.271, p = 0.015) and body satisfaction (r = 0.240, p = 0.032), but not with changes in body weight. Mediation analysis revealed that changes in body satisfaction (rather than body fat) mediated the relationship between group assignment and changes in negative emotions (mediator proportion = 18.7%). For community-dwelling Chinese postmenopausal women, an 8-week treadmill-based exercise intervention has beneficial effects on negative emotions. This improvement may be linked to changes in body composition and body satisfaction, particularly body satisfaction. Future research should further investigate the mechanisms through which exercise alleviates negative emotions in postmenopausal women
A155: The Impact of Internet-Based Screen Behavior on Physical Activity in Children and Adolescents
No full textAlthough previous studies have indicated that different types of screen time may be associated with insufficient physical activity in children and adolescents, the impact of various types of internet-based screen time on physical activity has not been sufficiently explored. Therefore, this study aims to investigate the specific impact of different internet-based screen usage on physical activity in children and adolescents through a two-year national cross-sectional survey. This study utilized cross-sectional survey data from the China Family Panel Studies, involving 5,770 children and adolescents aged 10 to 18 in 2020 and 2022. Physical activity frequency was assessed using a single question, with fewer than five sessions per week classified as insufficiently active. The survey also collected data on screen time frequency in online gaming, online shopping, online learning, short video, and WeChat usage. Generalized linear logistic regression models were applied, constructing three analytical models: Model 1 without variable control, Model 2 incorporating sociodemographic variables (age, gender, school level, and urban/rural location), and Model 3 further adjusting for sleep duration. The analysis in Model 1 showed that, compared with children and adolescents who did not use online learning, those who used online learning had 19% higher odds of insufficient physical activity (Odds Ratio [OR] = 1.19, 95% Confidence Interval [CI]: 1.05-1.33). After controlling for sociodemographic variables such as age, gender, school grade, and urban/rural location, the negative effect of online learning on physical activity persisted, with the proportion of insufficient physical activity increasing by 15% (OR = 1.15, 95% CI: 1.01-1.29). Additionally, after controlling for relevant variables, the effect of short video on physical activity began to emerge, with children and adolescents who have watched short videos having an 18% higher risk of insufficient physical activity compared to those who have never watched a short video (OR = 1.18, 95% CI: 1.01-1.29). Further control for sleep duration in Model 3 showed that the negative effects of online learning and short video on physical activity remained consistent with those in Model 2, with little change. Different types of Internet-based screen behavior have significantly different impacts on physical activity in children and adolescents, with online learning and short videos having a negative effect. The future should fully consider the impact of various types of screen behavior on physical activity in children and adolescents and develop targeted intervention measures
A265: Safety Assessment and Optimization Strategies for Children\u27s Outdoor Public Physical Activity Spaces
No full textOutdoor physical activity (PA) is essential for children\u27s healthy development. However, existing public spaces for PA harbor safety hazards, leading to frequent accidental injuries among children. Current research mainly focuses on individual spaces or singular risk factors, lacking a comprehensive safety assessment system. Guided by the child-friendly concept, this study aims to construct a safety assessment index system for children\u27s outdoor PA spaces, identify subjective and objective risk factors, and provide a scientific basis for urban planning. We integrated 11 national standards and industry guidelines, 125 core academic references, and field investigation data from 13 typical spaces in Shanghai (e.g., community parks and city squares). NVivo12 Plus was employed for three-level coding analysis (initial, focused, and axial coding). After achieving theoretical saturation and conducting reliability and validity tests, 32 key coding nodes were established. A questionnaire based on the 5-point Likert scale was designed and administered through stratified sampling (by gender, age, and income) to 561 caregivers with an effective response rate of 90.7%. SPSS 23.0 and AMOS 26.0 were utilized for reliability and validity tests, one-sample T-tests, and principal component analysis to determine the weights of each assessment indicator. This study developed a safety assessment system for children\u27s outdoor PA spaces, structured into 7 dimensions and 32 indicators. Key objective environmental factors influencing safety include site facilities (weight 0.240), spatial conditions (weight 0.161), and material conditions (weight 0.130). Specific indicators, such as ground surfacing characteristics and fall protection, require particular attention. Children\u27s behavioral levels (weight 0.289) and safety awareness (weight 0.251) are the most significant individual subjective factors. The contradiction between caregivers\u27 performance (weight 0.168) and insufficient actual participation highlights the urgent need to strengthen safety education and dynamic management. This study systematically quantifies safety risks in children\u27s outdoor public activity spaces, revealing complex multidimensional factor interactions. Three recommendations are proposed: (1) optimizing space design with enhanced ground safety and age-appropriate facilities; (2) implementing a dual-track monitoring system that incorporates smart sensors and manual inspections to monitor high-risk behaviors and assess facility conditions; (3) delivering tiered safety education for children, families, and communities. The research findings can provide standardized assessment tools for child-friendly city development, promote multi-sector collaboration, and enhance the safety of children\u27s outdoor PA to support their healthy growth. Future research could expand the sample scope to validate the assessment system\u27s universality
A103: Challenges and Future Directions in Physical Education
No full textPhysical education (PE) teachers are essential in promoting physical activity and healthy lifestyles. Yet, they confront significant challenges, including inadequate educational resources, limited professional development, and struggles in catering to students\u27 varied demands. Furthermore, the absence of institutional support and recognition frequently results in feelings of undervaluation, contributing to job dissatisfaction and burnout. These problems, combined with heavy workloads, create a cycle of stress and reduced effectiveness. This study aims to identify challenges and future directions in and provides insights into improving support systems and professional development opportunities to enhance the effectiveness of PE teachers. This study employs a mixed-methods approach, integrating quantitative surveys and qualitative interviews to gain a comprehensive understanding of the issues. Data were collected from 50 sports educators in Beijing. Surveys assessed resource availability, workload, and training needs, while semi-structured interviews explored daily challenges and coping strategies. The study reveals that participants cited inadequate resources and a scarcity of professional growth opportunities. Three key themes: 1) Addressing Varied Student Proficiency Levels: Educators face challenges in adapting instruction to meet the diverse needs of students. This often results in uneven academic progress, as teachers find it difficult to provide equitable support for students at different proficiency levels. 2) Insufficient Administrative Support: Many participants emphasized that the lack of adequate administrative backing has hindered the implementation of effective educational reforms. Educators reported feeling undervalued and unsupported, citing insufficient institutional recognition and resources as key factors contributing to low morale and reduced effectiveness in their roles. 3) Burnout from Excessive Workloads: A significant number of educators reported experiencing chronic burnout due to overwhelming workloads and competing demands. This burnout adversely affects their mental and physical well-being, ultimately diminishing their job performance and ability to engage with students. This study reinforces existing concerns about resource shortages and professional development gaps in, while also highlighting burnout and inadequate administrative support as critical issues. These findings align with previous research but further emphasize the need for systemic policy changes. Key limitations include sample size constraints and potential geographic bias. Future research should broaden its scope to diverse regions and examine the long-term impacts of targeted interventions. From a practical standpoint, these findings underscore the necessity of increased funding, comprehensive professional training, and stronger institutional support to enhance the quality and sustainability of
A130: Comparative Analysis of Aerobic Capacity in Female College Golfers of Different Levels
No full textA professional golf tournament typically consists of four rounds, with each round lasting at least 3.5 hours. During the competition, golfers are required to adhere to the principle of “walking briskly and playing steadily” to complete the entire tournament. Adequate physical fitness and good aerobic capacity are essential for athletes to sustain their performance. Superior aerobic endurance serves as the foundation for completing a golf competition. This study aims to compare and analyze the aerobic endurance indicators of female college golfers at different skill levels during their training phases, in order to enhance the aerobic capacity of golf athletes. Method: Eight female golfers were divided into two groups: a group (N1) and a general level group (N2). Using the Cosmed pulmonary testing device and Polar heart rate monitoring devices, indicators such as Respiratory Frequency (Rf), Ventilatory-Perfusion Ratio (VE/VO₂), Ventilatory-Carbon Dioxide Ratio (VE/VCO₂), Energy Expenditure (EEm), Heart Rate Recovery (HR), and Relative Oxygen Uptake (VO₂/kg) were measured during the exercise phase of the treadmill test. The data were analyzed using t-tests. 1) The only significant difference between the N1 and N2 groups was in Respiratory Frequency (Rf) (P \u3c 0.05), while other indicators showed no significant differences (P \u3e 0.05). 2) The mean values of VE/VO₂, VO₂/kg, and HR were higher in the N1 group than in the N2 group. 3) In the N1 group, VE/VO₂ and VE/VCO₂ were positively correlated (P \u3c 0.05). In the N2 group, EEm was positively correlated with Rf (P \u3c 0.05), while HR was negatively correlated with VE/VO₂ (P \u3c 0.05). 1) The N1 group had a higher VO₂/kg value than the N2 group, indicating more efficient energy uptake during exercise. 2) The N1 group had lower EEm values than the N2 group, suggesting that they consumed less energy during the same intensity of exercise. 3) The N1 group had lower Rf and VE/VCO₂ values than the N2 group, indicating stronger metabolic adaptation during high-intensity exercise. The high-level group demonstrated superior aerobic capacity compared to the general level group. Excellent aerobic capacity enables golfers to maintain their competitive form and optimal performance during high-intensity, continuous competitions

No full textDeep learning has become a key technology in enhancing sports performance, offering new possibilities for training optimization. This study aims to (1) explore the research progress on deep learning applications in enhancing sports performance and (2) analyze future trends in this field. Method: Data from 545 English-language publications (2015-2025) were extracted from the Web of Science Core Collection using keywords related to DL (e.g., CNN, LSTM) and sports performance (e.g., athletic training, motion analysis). CiteSpace 6.4R was employed for bibliometric, co-word, and burst-term analyses. 1) Since 2015, research in this field has steadily increased before plateauing, with the most significant rise from 2021 (73 articles) to 2022 (90 articles) and a peak in 2024 (107 articles). Leading contributors include China (206 publications), the U.S., Germany, Japan, Korea, India, and the U.K. 2) ImageNet Classification with Deep Convolutional Neural Networks is the most cited work, introducing AlexNet and demonstrating its performance on large-scale image classification, significantly influencing computer vision. This study explores deep learning’s application in sports performance, with most literature focusing on specific sports. 3) High-frequency keywords in sports include motion analysis, performance, task analysis, kinematics, gait analysis, and sports training, while in computing, they include deep learning, convolutional neural networks, activity recognition, human pose estimation, classification, and wearable sensors. 4) Research trends are reflected in emergent keywords. From 2015–2019, studies emphasized motion detection, image recognition, kinematics, and image motion analysis for improved motion monitoring and assessment. From 2020–2025, a shift toward velocity, task analysis, gait analysis, and three-dimensional displays highlights a focus on individualized assessment and optimized training. Pose estimation, sports training, IoT, and virtual reality remain active, underscoring the role of deep learning in intelligent sports performance analysis. 1) Over the past decade, research on deep learning for sports performance has grown rapidly before stabilizing, with China, the U.S., Germany, Japan, Korea, India, and the U.K. leading the field. 2) The focus has shifted from general motion detection to refined applications like gait analysis, velocity estimation, and task analysis, though most studies prioritize computational methods over sport-specific needs. 3) Research trends emphasize integrating deep learning, including CNNs and pose estimation, into performance analysis. While progress has been made in motion monitoring, further exploration of sport-specific applications is needed. 4) Advancements in AI and sports science will drive intelligent training, injury prevention, and performance optimization, benefiting both competitive sports and public health
A232: The Voice-Inclusive Physical Education Class: Primary School Physical Education Teaching Mode Under New Curriculum Standards
No full textCurrent physical education classes in primary schools face a lot of challenges, such as the low student participation, a dull class environment, and a lack of students’ voice, which has a negative impact on teaching effect and students’ physical and mental health. This study employed the action research method to organize the physical education classes in primary school based on the New Curriculum Standards. The study encouraged primary school students to actively express their understanding and feelings about physical education activities and guided them to enthusiastically participate in the design of teaching content and activities to construct the “voice-inclusive” physical education classes. And it also elaborated the connotation and meaning of the “voice-inclusive” physical education classes. Additionally, the study proposed solutions to solving the practical teaching problems for primary school physical education teachers by means of updating teaching philosophies, optimizing teaching contents, rebuilding teaching assessment systems, and dealing with students’ individual differences. The results of this study demonstrated that the “voice-inclusive” physical education classes abandon the traditional teacher-dominated teaching mode that overlooks the students’ individual differences and put greater emphasis on the student-centered teaching mode. Such “voice-inclusive” physical education classes can effectively stimulate students’ desire to voice, enhance their participation in activities, foster a positive and dynamic class environment, and promote students’ development of physical and mental health. These results can also provide valuable insights for improving the teaching quality of primary school physical education and advancing primary school students’ healthy growth
A156: Research on the Optimization of China\u27s Community Sports Policies from the Perspective of Policy Tools
No full textCommunity sports are a key area for promoting the in-depth development of socialized sports for all. This study aims to reveal the current application status and optimization paths of community sports policies in China through policy tool analysis and promote the high-quality development of community sports. The research focuses on the distribution characteristics of policy tools and the participation of multiple stakeholders, providing a scientific basis for policymakers. Method: This study selected 30 community sports policy documents issued by the state from 2004 to 2024. NVivo12 qualitative analysis software was used in combination with content analysis to construct a two-dimensional analysis framework. The study encoded and analyzed the policy documents from two dimensions: policy tools (supply-oriented, environmental, and demand-oriented) and policy utility subjects (government, social organizations, enterprises, and individuals). Through quantitative analysis, the frequency and distribution of policy tools were revealed. Research findings indicate that the distribution of community sports policy tools is uneven. Supply-oriented policy tools dominate (55.98%), mainly focusing on human resource support and infrastructure construction, but financial investment is severely insufficient (4.83%). Environmental policy tools are relatively weak (38.61%), with a clear bias towards goal planning and legal regulation, while tax and financial incentives are almost ignored. Demand-oriented policy tools are at a disadvantage (5.41%), with overseas exchanges being dominant, but government procurement and service outsourcing are seriously lacking. The analysis of the main policy effect subjects shows that the government and social organizations are the main drivers, while the participation of enterprises and individuals is relatively low. The results of this study indicate that there is a significant imbalance in the current community sports policy in terms of the use of policy tools and the participation of multiple stakeholders. It is suggested that the top-level design of community sports policy be improved by rationally allocating policy elements, optimizing the proportion of policy tools, balancing the participation of multiple stakeholders, and promoting the scientific production of policies. Future research should further track the policy-making process and explore the policy diffusion mechanism to promote the effective implementation and continuous improvement of community sports policies
A169: Physical Education Teachers\u27 Role Reconstruction in P.E.-Education Integration: A Systematic Review
No full textThe integration of sports and education policies in China has driven the redefinition of the role of physical education (PE) teachers, shifting their responsibilities from traditional instructional tasks to multifaceted competencies that encompass teaching, coaching, and holistic student development. Despite increasing emphasis on cultivating dual-qualified educators (possessing both pedagogical expertise and athletic training proficiency), systemic challenges persist, including fragmented training mechanisms for dual-role teachers, insufficient research on the career adaptability of retired athletes transitioning into teaching roles, and the absence of unified standards for evaluating teachers’ integrated in-class and extracurricular competencies. This study systematically reviews these gaps to establish a cohesive framework for PE teacher role reconstruction under the sports-education integration policy, proposing context-sensitive strategies for policy refinement and professional development. This research employs a mixed methods approach, combining a systematic literature review (2017–2025) of peer-reviewed articles from CNKI, Google Scholar, and policy documents (e.g., Measures to Strengthen the Development of Primary and Secondary School PE Teachers in the New Era) with qualitative case analyses of regional pilot programs. Three dimensions are examined: (1) adapting vocational dual-qualified frameworks to PE via certification criteria and incentives; (2) barriers to retired athletes’ teaching transitions, assessed through interviews; (3) competency standards aligned with extracurricular and community engagement policies. The study identified three distinct pathways for role reconstruction. First, dual-qualified PE teacher frameworks require discipline-specific adaptations, such as mandating concurrent possession of coaching certifications and teaching credentials, alongside dynamic competency re-evaluation mechanisms. Second, retired athletes face challenges in classroom management and curriculum design, necessitating tiered certification pathways and immersive pedagogical training modules. Third, competency standards must incorporate quantifiable metrics for extracurricular contributions and multi-stakeholder feedback mechanisms to ensure equitable evaluation. Conclusions/Discussion: This study highlights the interdependence of policy coherence, resource allocation, and institutional adaptability in redefining PE teachers’ roles. The dual-qualified framework demands cross-sector collaboration, while retired athlete integration requires hybrid training models that recognize athletic expertise (e.g., expedited certification for elite athletes) while addressing pedagogical gaps through partnerships with teacher-training institutions. Furthermore, competency standards should adopt adaptive metrics to accommodate regional disparities (e.g., urban-rural divides in sports infrastructure) and leverage emerging technologies (e.g., AI-driven simulation platforms for classroom scenario training) to enhance scalability. Future research should explore the longitudinal impacts of role reconstruction on student outcomes and examine the contextual applicability of global initiatives, such as sport-for-development programs
