A042: Research on the PE System of Learning, Practicing, and Competing from the System Theory Perspective
No full textExploring physical education courses that promote students\u27 physical health and the learning, practicing, and competing system is a topic of concern for physical education researchers. Currently, research on the topic mainly focuses on the student object aspect, and there is a lack of research on the subject aspect. This study is based on system and group dynamics theory, optimizing the construction of a learning, practicing, and competing physical education system, aiming to enrich the physical education and training mode in universities and promote the development of students\u27 physical health. Method: This study adopts the logical analysis method to systematically analyze the overall, interrelated, hierarchical, and dynamic characteristics of the learning, practicing, and competing physical education system. The case analysis method takes Northwestern Polytechnical University as a case study for analysis. Based on system theory, there exists a systemic and interactive relationship between physical education and the “five educations” integration of morality, intelligence, aesthetics, and labor; Within the physical education system, there are multiple departments, personnel, and levels of characteristics such as student affiliation, student work management, and student sports training in the subject aspect, while there are ontological attributes such as different sports needs and physical conditions of students in the object aspect; Based on the theory of group dynamics, this study explore the characteristics of different subjects and constructs a physical education system that is suitable for the collaborative development of learning, practicing, and competing in universities, taking into account multiple dimensions such as system, organization, content, form, and evaluation, in accordance with the objective attributes of students; Through the analysis of five years of physical education cases at Northwestern Polytechnical University, the compliance rate of students\u27 physical health has increased from 88.03% to 97.63%. The five-dimensional collaborative learning, practicing, and competing physical education system has high scientific, systematicity, and operability. Integrity and interactivity are the foundation for building a physical education system in the “five educations” integration of universities. Based on the characteristics of the internal subject and object of the physical education system, the optimized and constructed multi-dimensional collaborative development system of learning, practicing, and competing in terms of system, organization, content, form, and evaluation is a scientific and feasible physical education system
A112: Analysis of Attention Allocation in Fitness and Leisure Industry Policies of Local Governments
No full textIn 2016, China issued the Guidance on Accelerating the Development of the Fitness and Leisure Industry, after which local governments successively promulgated related policies. As key actors in policy implementation, the rationality of attention allocation in their policies directly impacts policy outcomes. Based on attention allocation theory, this study explores provincial government promotion plans for the fitness and leisure industry from multiple dimensions, analyzing differences in attention allocation among provincial governments, with the aim of providing references for advancing high-quality development of the industry. Policy texts from 29 provincial-level regions were collected through official government portals. Using NVivo 11 software, the texts were processed and analyzed. Two coders familiar with policy analysis conducted the coding, and one randomly selected policy text was subjected to consistency verification. Two main functions of the software were applied: first, the word frequency query function to broadly grasp policy content; second, the coding function to establish an analytical framework. Through sentence-by-sentence coding of the 29 policy texts, 9 parent nodes and 46 child nodes were established, totaling 1,001 reference nodes. The top three-word frequencies were sports, development, and exercise. Over time, local governments’ attention to the fitness and leisure industry shifted from an initial concentrated focus to a gradual decline, reflecting waning interest in nationally set policy objectives. In terms of policy formats, local policies were largely similar. Reference node values revealed that local governments allocated more attention to improving service systems, strengthening organizational guarantees, and enhancing infrastructure construction, while less attention was directed toward advancing R&D and manufacturing of equipment or optimizing industrial structures and layouts. Conclusions/Discussion: The development of the fitness and leisure industry is an inevitable trend driven by China’s socioeconomic progress. Local governments should rationally allocate attention based on regional characteristics to address shortcomings in policy formulation and implementation, ensuring policies effectively propel industry growth. While this study’s use of NVivo coding may be subject to coder bias, it interprets the content framework of fitness and leisure industry policies through the lens of attention allocation, enriching academic understanding of policy implications and contributing to industry advancement
A279: The Relationship Between Adolescent Sports Participation and Quality of Life: A Moderated Mediation Model
No full textThe study focuses on how sports participation reduces interpersonal sensitivity through enhancing social skills and promoting peer interaction, which in turn affects the quality of life of adolescents. At the same time, a gender perspective is introduced to analyze the heterogeneity of different gender groups in terms of sports participation, interpersonal sensitivity, and quality of life, and to reveal the moderating role of gender factors in the pathway of “sports participation - interpersonal relationship sensitivity - quality of life”. This will provide empirical evidence for education departments to develop differentiated exercise intervention programs and for mental health organizations to design targeted counseling strategies. A random sample of 9504 high school students from 16 prefecture-level cities in Shandong Province was selected and surveyed using the School Social Behavioral Scale (SSBS), the Symptom Checklist 90 (SCL-90), the Physical Activity Questionnaire for Adolescents (PAQ-A), and the Scale for Children and Adolescents (QLSCA). A moderated mediated effects model was constructed. Girls scored higher than boys in interpersonal sensitivity (t=-4.19), and boys scored higher than girls in quality of life (t=4.97) and sports participation (t=19.10) (all p-values \u3c0.01). Sports participation was positively correlated with quality of life (r=0.287) and negatively correlated with interpersonal sensitivity (r=-0.127); interpersonal sensitivity was negatively correlated with quality of life (r=-0.546) (all p-values \u3c0.01). Interpersonal sensitivity exerted a mediating effect between sports participation and quality of life (mediating effect value of 0.034,95% CI=0.043 to 0.068). Gender played a moderating role in the sports participation and quality of life pathways (β=0.033, P\u3c0.01). Interpersonal sensitivity plays a mediating role between adolescent sports participation and quality of life, and sports participation can improve adolescents\u27 quality of life levels by decreasing their interpersonal sensitivity and thus improving their quality of life. Gender moderated the relationship between sports participation and quality of life, and sports participation was more strongly associated with quality of life in girls. The study suggests that schools and families should pay attention to the quality of life of adolescents, strengthen the monitoring and assessment of mental health, and especially formulate intervention strategies based on gender differences, create a favorable environment for the comprehensive development of adolescents through the collaborative mechanism of home and school
A116: Resistance Training vs. Moderate-Intensity Continuous Training on Cognitive Function in NAFLD Patients
No full textNon-Alcoholic Fatty Liver Disease (NAFLD) is the most common chronic liver disease globally, with a prevalence of nearly 30%. It is closely related to cognitive dysfunction, which significantly impacts quality of life. Recent studies suggest that exercise therapy (aerobic/resistance training) can improve metabolic abnormalities in NAFLD, yet its effects on cognitive function remain controversial. Moderate-Intensity Continuous Training (MICT) may have advantages over Resistance Training (RT) in modulating lipid metabolism, though RT might be more feasible for specific groups. This study compares the effects of 6 weeks of MICT and RT on cognitive functions (verbal memory, visuospatial ability, executive function, and attention) in NAFLD patients. A single-center, single-blind, randomized controlled trial (RCT) was conducted with 36 NAFLD patients, randomly assigned to either the MICT group (N=18) or the RT group (N=18). Cognitive function was assessed using MOCA, RAVLT, ROCF, TMT, and DSST. The study lasted 6 weeks with three exercise sessions per week. Data analysis was performed using linear mixed-effects models. (1) MOCA: No significant effects for time (P\u3e0.05) or group (p\u3e0.05). RAVLT: Both groups significantly improved short-term recall (MICT: 2.17 points, P=0.003, COHEN’s D=0.76; RT: 2.39 Points, p = 0.001, C d = 0.84). (3) ROCF: Short-term delayed recall: MICT showed greater improvement (9.778 Points, p \u3c 0.001, d = 1.32), while RT improved by 5.389 POINTS (p = 0.014, d = 0.73). Long-term delayed recall: only MICT significantly improved (11.444 POINTS, p = 0.008, d = 1.01). (4) TMT-A: no significant improvement in either group (MICT: 3.214 seconds, p = 0.142, d = 0.22; RT: 3.618 seconds, p = 0.123, d = 0.19); TMT-B: RT showed significant improvement (δ = 31.31 seconds, p = 0.006, d = 1.24). (5) DSST: RT showed significant improvement (δ = 11.22 points, p = 0.014, d = 0.91). Both exercise interventions showed dimension-specific benefits in NAFLD patients. RT was most effective for executive function and attention, while MICT improved visuospatial memory. Both interventions similarly improved verbal memory. Tailored exercise prescriptions are recommended based on specific cognitive deficits in NAFLD patients
A105: A Canonical Correlation Analysis of Motor Skills and Physical Fitness in Children with Intellectual Disabilities
No full textWhile fundamental movement skills (FMS) and physical fitness are critical for children with intellectual disabilities, their multidimensional interactions remain poorly characterized. This study aimed to elucidate the structural associations between FMS (locomotor and object control skills) and physical fitness in children with intellectual disabilities using canonical correlation analysis (CCA). Method: A cross-sectional design included 207 children with intellectual disabilities (aged 6–18 years, mean age=13.13±3.14). Thirteen FMS were assessed via the TGMD-3 tool, and seven physical fitness indicators (e.g., 50m sprint, standing long jump, TUG test) were measured. Statistical analyses, including CCA and regression modeling, were conducted using SPSS 27.0. The study found that the first pair of canonical correlation coefficients between the two sets of variables reached 0.829 (p \u3c 0.001), indicating a significant positive correlation between motor skills and physical fitness. The canonical structure analysis revealed that the core associated factors of physical fitness were lower limb explosive power (Standing long jump, r = 0.951), speed quality (50m sprint, r = 0.891), and balance (TUG, r = -0.604). These main physical fitness factors were significantly related to multi-dimensional motor skills, among which lateral shuffle (0.773), single-foot hop (0.863), kicking a stationary ball (0.784), and stationary dribbling (0.733). Redundancy analysis indicated that the typical variable V1 could explain 50.1% of the total variance of physical fitness and 34.5% of the variation in motor skills. Regression analysis further confirmed that lower limb explosive power (R² = 0.578) and speed quality (R² = 0.525) had the strongest predictive effect on the variation of motor skills, while flexibility (sit-and-reach test) had no significant impact (R² = 0.001). The study identified a bidirectional reinforcement mechanism between power-speed capacities and object control proficiency, with coordination deficits reflected in TUG performance potentially limiting dynamic balance development. These findings underscore the necessity of integrating lower-limb strength training (e.g., plyometrics) and task-specific skill interventions (e.g., ball control drills) to enhance motor performance in children with intellectual disabilities. The results provide a theoretical foundation for designing precision rehabilitation programs that synergistically target physical fitness and FMS development
A250: Children\u27s Volleyball for Health and Transition from Kindergarten to Primary School Under New Curriculum Standards
No full textIn early childhood sports education, health promotion, and the seamless connection between early childhood and primary school sports are critical issues. Early childhood represents a pivotal stage for children\u27s physical development, during which volleyball can significantly enhance teamwork, coordination, and overall fitness. Despite growing research interest in this area, significant gaps remain in leveraging early childhood volleyball as a tool for promoting health and ensuring a smooth transition from early childhood to primary school sports. Documentation Research Method: Review literature for research status and theoretical support. Questionnaire Survey Method: Survey teachers, parents, and children on early childhood volleyball and transition challenges. Case Analysis Method: Examine successful early childhood volleyball programs to identify best practices. Action Research Method: Fifty 6-year-old children were selected and randomly assigned to an experimental group and a control group. The experimental group participated in structured volleyball activities, including underhand ball receiving, net tossing, net striking, ball holding, and ball receiving exercises, designed to enhance basic motor skills and volleyball techniques. The control group received standard volleyball instruction. Pre- and post-intervention assessments were conducted using a 30-meter sprint and self-ball juggling test to evaluate the children\u27s motor abilities and technical proficiency. The results indicated significant improvements in the experimental group\u27s motor skills and volleyball techniques compared to the control group. Volleyball participation significantly enhances motor skills, emotion regulation, and teamwork abilities. Children who participated in volleyball programs demonstrated superior fitness levels, emotion management capabilities, and teamwork competencies compared to non-participants. Key transition challenges identified include inconsistencies in curriculum design and a shortage of qualified teaching staff. Post-intervention optimized programs effectively improved motor skills, enhanced sports interest, and fostered a positive attitude toward physical activity. Early childhood volleyball promotes overall development by improving motor skills, regulating emotions, and fostering teamwork. For effective transition, aligned curriculum models and content, consistent teaching methods, and enhanced communication are essential. Kindergartens and primary schools should jointly develop volleyball curriculum standards and strengthen teacher team building. This study offers practical and theoretical insights for early childhood volleyball education, emphasizing the need to consider individual differences and ensure fun, diverse activities. Future research could explore integrating volleyball with other sports for a more comprehensive early childhood sports education, delve into teacher training and curriculum development to sustainably develop early childhood volleyball education

A085: Analysis and Implications of the Standards for Health-Promoting Schools in Europe
No full textThe Health Promoting School (HPS) is an educational model that promotes students\u27 health literacy through creating a healthy environment and building internal capacities. Since its pilot implementation in 1995, China has still faced structural challenges such as low policy execution efficiency and the lack of a family-school-community collaboration mechanism. In contrast, the forward-looking governance framework and practical validation advantages of the European Standards for Health Promoting Schools (ESHPS) offer valuable references. Based on this, the study aims to interpret and analyze the European HPS standards and provide targeted insights to guide the development of Health Promoting Schools with Chinese characteristics and advance health education. The study employs literature review and logical analysis methods to interpret and analyze ESHPS and provides targeted insights for the development of Health Promoting Schools in China. The ESHPS is based on a three-dimensional framework of inputs, process interventions, and outcomes, facilitating effective mechanisms to enhance health literacy through dynamic collaboration across four levels: policy, schools, communities, and students. Its dynamic governance logic builds an operational system through democratic consultation, community empowerment, and other strategies. Although China’s standards rely on quantitative indicators for pilot promotion, challenges remain, such as outdated standards and a lack of policy coordination. Therefore, China needs to optimize Health Promoting Schools by improving standards, ensuring standardized construction, promoting integrated family-school-community participation, and enhancing the professional development of health education teachers. Conclusions/Discussion: The analysis of ESHPS essentially aims to promote local standard innovation by drawing on successful foreign experiences. However, there is a gap in institutional adaptation when transplanting such experiences, and the development of health-promoting school standards is not only a matter of policy implementation but also involves the transformation of educational concepts and social culture. Future research should focus on exploring the causal relationships between the outcomes of foreign experiences, based on an understanding of the successful experiences of developed countries, as well as how to achieve the localization and innovative transformation of international experiences in the present context. By coupling the advantages of foreign paradigms with local governance contexts and achieving a shift from compliance with standards to a quality-oriented paradigm based on cultural subjectivity, a Chinese solution that integrates scientific and humanistic aspects can ultimately be formed
A253: Examining Health Variations Between Resistance Training with/without Breathing Retraining in Overweight Young Women
No full textPhysical inactivity and overweight are public health concerns among young Chinese women. A decrease in respiratory strength and endurance has been reported in obese/overweight individuals, as the increased fat accumulation in the chest wall and trunk leads to weakness of the respiratory muscle and changes in breathing patterns, resulting in decreased lung ventilation, the capacity for oxygen delivery, and utilization. Studies showed that RT can increase cardiopulmonary function as shown by improvement of submaximal exercise and increased peak oxygen uptake (VO2peak), resulting enhancement of muscle hypertrophy. Breathing retraining (BR) can also manipulate breathing patterns. Therefore, the purpose of this study was to investigate the effects of RT and RT plus BR on pulmonary function, circulatory parameters, and aerobic capacity in young women. 24 young females were randomly allocated into the resistance training group (RT) and the resistance training combined with breathing retraining group (RT+B), and performed exercise training for eight weeks, three sessions/week and 60 minutes/session. 12 age and BMI-matched overweight young females were also recruited as the control group (C). The study procedures were approved by the Tianjin Sport University Ethical Advisory Committee (TJUS2024-032) and adhered to the Declaration of Helsinki. This study was registered on Clinical trials. Gov (ID: ChiCTR2400089050). Significant decreases in BMI, total body fat, TG, and LDL-c were observed in the two exercise groups (p＜0.05). In both exercise groups, significant increases in VO2peak were accompanied by noticeable increases in VC, FVC, MVV, FEV1, PEF, and decreases in SBP, DBP, SBP2, cSBP, and rAI (p＜0.05). The Group RT+B significantly higher increases in VO2peak, AT, and oxygen pulse level than those of the control and Group RT (p＜0.05). The main findings showed that RT and RT combined with BR improved respiratory function, lowered peripheral and central blood pressure, and regulated lipid profiles. The RT combined with the BR program achieved better effects in VC, MVV, SBP2, and cSBP than RT alone. Finally, only RT combined with the BR group significantly increased AT and peak oxygen pulse
A238: Occupational Prestige, Intergenerational Capital, and Sports Participation: A Multilevel Analysis of Social Inequality in China
No full textPhysical activity (PA) is essential for public health, yet socioeconomic disparities persist. This study explores the impact of occupational prestige—measured by the International Standard Classification of Occupations Prestige Scale (SIOPS)—and intergenerational family capital on PA engagement among Chinese adults. Additionally, it examines whether government policy interventions can alleviate these inequalities. Method: Using data from the 2021 China General Social Survey (n = 623) and provincial statistical yearbooks, an ordered logistic regression model assessed the influence of individual and family SIOPS scores on weekly PA duration. Government funding for sports infrastructure was tested as a moderating factor through interaction terms. To address endogeneity, instrumental variable regression (IV-2SLS) was used with parental education as an instrument for SIOPS. (1) Occupational Prestige: Higher SIOPS scores were positively associated with PA participation (β = 0.502, 95% CI [0.45–0.55], p \u3c 0.001), reflecting economic and cultural advantages. (2) Intergenerational Influence: Family SIOPS significantly PA participation (β = 0.091, p \u3c 0.001), highlighting the role of social networks and educational transmission. (3) Policy Moderation: Government funding effectively reduced socioeconomic disparities (p = 0.014). In underdeveloped regions, a 1% increase in funding PA inequality by 2.15-fold (p \u3c 0.05). Socioeconomic status and intergenerational capital jointly shape PA behaviors, reinforcing existing inequalities. Targeted policies—such as expanding access to sports facilities and fostering PA-friendly cultures—can enhance equity. Future research should investigate long-term trends and extend interventions to underserved rural communities
