A089: Value Reconstruction and Practical Dimensions of AI-Empowered Reform in University Physical Education
No full textDriven by educational digital transformation and the iterative advancement of artificial intelligence (AI), university physical education is undergoing a paradigm shift from an experience-driven to a data-driven model. Method: Based on the theoretical framework of digital educational transformation, this study systematically explores the value positioning, technical pathways, and practical challenges of AI in reforming physical education. Artificial Intelligence intervenes in pedagogical change through three important domains and reveals multiple realities of obstruction in current practice: Instructional Mode: By leveraging intelligent perception and learning analytics technologies, AI establishes personalized exercise prescription systems, transitioning from standardized teaching to precision-guided instruction. Evaluation System: Integrating computer vision and biomechanical dynamic process diagnostics, AI develops dynamic skill assessment models, shifting summative assessments to developmental diagnostics. Resource Management: Utilizing digital twin and virtual simulation technologies, AI transcends spatial-temporal constraints of traditional teaching, creating smart physical education environments that enhance embodied cognition and contextualized learning experiences. Through constructing a closed-loop system encompassing data collection-intelligent decision-making-feedback, AI significantly improves injury prevention effectiveness, optimizes skill acquisition pathways, and expands ideological-political educational integration within physical education. Artificial intelligence intervenes in three dimensions: educational subject, process, and space to realize the reform of physical education teaching in colleges and universities. The study further identifies critical implementation barriers: technical incompatibility arising from industrial algorithms misaligned with educational needs, governance challenges in ethics due to inadequate protection of sports data privacy, and diminished technical efficacy caused by insufficient teacher AI literacy. To address these issues, future reforms should prioritize three collaborative dimensions: developing lightweight educational-specific algorithm models, establishing multi-stakeholder data governance mechanisms, and reshaping teacher roles through digital coach training systems. The deep integration of AI and physical education transcends mere instrumental innovation, representing an intelligent return to the essence of holistic development through physical education. Its advancement must adhere to pedagogical primacy, fostering symbiosis between disciplinary knowledge and digital intelligence through technological innovation. This process necessitates balancing algorithmic precision with educational complexity, harmonizing data-driven rigor with the artistry of pedagogy, and integrating technological empowerment with the cultivation of sports literacy
A306: Assessment of Gross Motor Skill Development in Preschool Children: A Movement Quality Perspective
No full textThis study examines the development level of gross motor skills in preschool children from the perspective of movement quality assessment. Early childhood represents a critical period for developing foundational motor skills that significantly influence children\u27s physical health, cognitive development, and future academic achievement. However, current evaluation methods often lack comprehensive frameworks that effectively capture the quality and nuances of children\u27s gross motor movements. Therefore, the primary objective of this research is to construct a detailed and comprehensive assessment framework specifically tailored to evaluate the quality of gross motor skills in children aged 3–6 years. Method: To achieve this objective, the study employed a rigorous methodology involving multiple research techniques. Initially, a thorough literature review was conducted to identify existing assessment models and indicators relevant to preschool gross motor skills. This step was complemented by expert interviews, engaging professionals in early childhood education, developmental psychology, and pediatric physiotherapy to gain deeper insights. Furthermore, field observations in preschool settings provided practical data on children\u27s motor activities. Subsequently, a Delphi method involving iterative consultation with experts was utilized to refine the identified indicators and establish their relative importance, ensuring the reliability and validity of the assessment tool. Following the development of this refined assessment framework, a cohort of preschool children was evaluated, systematically examining their performances in specific domains of balance, locomotion, and object manipulation across different age groups. The results clearly indicated a distinct age-related progression pattern in gross motor skill development among preschoolers. Specifically, significant improvements were observed in balance and locomotion skills as age increased. In contrast, object manipulation skills exhibited considerable individual variability, underscoring the necessity for individualized assessments and targeted interventions. The findings highlight the importance of employing precise and comprehensive assessment tools to monitor and support the motor development of preschool-aged children. Practical intervention strategies and tailored recommendations were proposed based on the study outcomes, providing educators and caregivers with essential resources to foster optimal gross motor skill development during the crucial preschool years

Due to limitations in sample size and technological development, future research can be expanded to different educational environments and combined with multiple assessment methods
A084: Effects of Aerobic Exercise on Fatigue Characteristics of CUMS Depression Model Rats
No full textIn this study, solitary nursing and chronic unpredictable mild stress (CUMS) were used to establish a depressed rat model. The influence of aerobic exercise on the fatigue of depressed animals provides experimental reference for the practice of exercise therapy for depression. The purpose of this study was to establish a CUMS depressed rat model. The aerobic exercise intervention was carried out on the depressed rats on a rotating treadmill. Method: Behavioral tests, such as body weight and sugar, and water preference, were conducted to verify the establishment of the depression model and the antidepressant effect of aerobic exercise. Biochemical fatigue, such as blood ammonia, corticosterone, and testosterone, was determined, and correlation analysis of “behavioral indexes- fatigue indexes” in depressed rats was conducted. After three weeks of modeling, compared with normal rats, the body weight, sugar water preference, and other indicators of depressed rats were significantly decreased (p \u3c 0.05 or p \u3c 0.01), indicating that the depression modeling was successful. After four depression significantly reduced (p \u3c 0.05 or p \u3c 0.01), indicating that aerobic exercise has a good anti-depression effect. Correlation analysis showed that there was significant correlation between serum ammonia, testosterone, and corticosterone fatigue in behavioral indexes in depressed rats (r\u3e0.5 and p \u3c 0.05). Aerobic exercise can significantly improve depressive behavior in stressed rats, and the combination of fatigue and behavioral inhibition can enrich the evaluation content of exercise therapy for depression
A063: Research on the Load Characteristics of Female College Volleyball Players in Consecutive Matches
No full textThis study aims to analyze and compare data such as total movement load, movement load at different speed zones, physical load, jumps, and heart rate obtained from female college volleyball players during consecutive matches. The goal is to explore the load characteristics and patterns of the Chinese female college volleyball program in consecutive matches, thereby providing a data-driven explanation for fatigue accumulation and performance during these matches. This will offer scientific support for coaches in designing training plans. The study involved 12 female volleyball players from Nanjing Normal University, who participated in the 2024 Jiangsu Provincial High-Level College Volleyball Championship. The players wore K-sport IMU (K-AI Track, K-sport, Italy) motion monitoring systems and FirstBeat (FirstBeat, Garmin, Finland) heart rate monitoring systems during 4 matches over 3 consecutive days. Indicators of each match were compared and analyzed using SPSS 27.0 software, with the level of significance set at P \u3c 0.05. During consecutive matches, the average total movement load per match for female college volleyball players was 816.8 ± 124.6. The movement loads at different speed zones were as follows: Training Load Stand ≤ 0.2g was 138.5 ± 13.7; 0.2g ≤ Training Load Low ≤ 0.75g was 420.8 ± 53.9; 0.75g ≤ Training Load Medium ≤ 1.5g was 195 ± 43.6; Training Load High \u3e 1.5g was 61.8 ± 14.8. The physical load value was 112 ± 18, and the average number of jumps per match was 14.3 ± 3.8. The average heart rate per match was 120.8 ± 16.7 beats per minute, with a maximum heart rate of 201.3 ± 5.8 beats per minute and a minimum heart rate of 66.3 ± 10.3 beats per minute. Conclusions/Discussion: The total movement load of female college volleyball players in consecutive matches initially decreased and then increased as the matches progressed. Analysis of movement loads at different speed zones revealed that the 0.2g ≤ Training Load Low ≤ 0.75g and 0.75g ≤ Training Load Medium ≤ 1.5g zones showed an increasing trend, while the Training Load High \u3e 1.5g zone decreased. Significant differences were observed in total movement load and physical load between the first and third matches. Additionally, significant differences in jumps were found between the second and third matches. During consecutive matches, the average heart rate of players showed a declining trend. Specialized training should focus on improving players\u27 jumping ability, movement efficiency, and competitive strength. Training loads should be set at or above the levels required during matches to ensure optimal performance

(1) The number of publications in China remained relatively stable, while international publication volume showed a gradual upward trend; (2) Compared with domestic institutions, international institutional collaboration was more intensive; (3) High-frequency keywords in Chinese literature focused on metabolic regulation aspects such as “aerobic exercise” and “blood glucose,” while international studies placed greater emphasis on interdisciplinary mechanisms such as “physical activity” and “insulin resistance”; (4) Burst keyword analysis indicated that domestic research hotspots are gradually shifting toward emerging fields like gut microbiota and sarcopenia, while international studies are delving into cutting-edge directions such as molecular mechanisms and digital interventions. (1) Domestic research emphasizes exercise prescriptions and metabolic improvement, but lacks interdisciplinary collaboration; in contrast, international research highlights the broad concept of physical activity and its associations with psychological and physiological factors, with more mature technological integration; (2) Future efforts should strengthen multidisciplinary collaboration and build intelligent, personalized, and full-course intervention systems to achieve more scientific and effective prevention and treatment of diabetes
A204: Effects of Different Stance Widths and Foot Angles on Squatting in Male College Students
No full textThis study aims to explore the impact of different station widths and foot deviant angles on the lower limb muscle coordination pattern during provide a basis for optimizing squat training. 20 male college students were recruited to conduct squat tests based on different stance distances and foot deflection angle combinations. The participants squatted down at a constant speed until their hips touched the marking rope position and then stood at a constant speed (the time is 3s-1s-3s). Data were collected using motion capture and electromyography test systems, and two-factor ANOVA statistics were counted through repeated measurements. 1) During the squat phase, the peak activation rate of gluteus maximus is affected by the interaction between the station distance and the foot deflection is significantly improved at a 30° wide distance; the peak activation rate of the long head of the biceps femoris is high at deflection angles. The average activation rate of some muscles is also affected by the two. 2) During the ascending stage, the peak activation rate of the tibial anterior muscle is higher at deflection angle; the average activation rate of the long head of the biceps femoris is higher at narrow distances, and the average activation rate of some muscles is higher at deflection angle. 3) The percentage of tibial anterior muscle activation is the highest in the squat stage, and the percentage of long head activation of biceps femoris in the ascending stage is the highest. During squatting, the lateral gastrocnemius and soleus muscles are activated first, and the activation sequence in the ascending stage is greatly affected by the foot deflection angle. When squatting at 30°, the difference in the EMG signal amplitude of the tibial anterior muscle and gluteus maxillary muscle is minimal. Research shows that during the squatting phase, a wide stance of 30° can increase the range of motion of the hip joint, and some muscles are related to ankle stability. During the ascending phase, a narrow stance can increase the flexion angle of the knee joint. The tibialis anterior and gluteus maximus are heavily loaded, and coordination is better when the wide stance is 30°. Different phases have their own muscle activation characteristics. During training, attention should be paid to stance distance and foot deflection to activate the target muscles
A220: Work Memory of ADHD Children: A Network Meta-Analysis of the Effects of Different Exercise Modalities
No full textPhysical exercise, spanning from early childhood to adulthood, exerts positive influences on cognitive function. This study employed systematic review, network meta-analysis, and traditional meta-analysis to investigate the interventional effects of exercise on working memory in children with Attention Deficit Hyperactivity Disorder (ADHD). Relevant literature was retrieved from multiple databases. After screening and data extraction, study quality was assessed using the Cochrane Risk of Bias Tool. Meta-analysis, sensitivity analysis, and publication bias analysis were conducted using Review Manager 5.4 and Stata 18.0 to evaluate the impact of exercise on working memory in children with ADHD Among 1,296 screened studies, 49 met the inclusion criteria, with 21 included in the meta-analysis. Results demonstrated that exercise significantly improved working memory in children with ADHD (P \u3c 0.05), including both spatial and verbal working memory. Subgroup analysis revealed optimal spatial working memory improvements with interventions lasting 8–12 weeks, 3–4 sessions per week, and 60–90 minutes per session (P \u3c 0.05). For verbal working memory, ≥5 sessions per week and sessions exceeding 90 minutes were most effective (P \u3c 0.05). Network meta-analysis indicated that multi-component exercise programs (e.g., combined aerobic and resistance training) were superior for spatial working memory, while virtual reality (VR)-enhanced training showed advantages for verbal working memory. Sensitivity and publication bias analyses confirmed result robustness, with a low likelihood of publication bias. Conclusions/Discussion: Physical exercise improves both spatial and verbal working memory in children with ADHD. Interventions lasting ≥12 weeks, 3–4 sessions per week, and 60–90 minutes per session optimize spatial working memory, whereas 8–12 weeks, ≥5 sessions per week, and sessions \u3e90 minutes enhance verbal working memory. Multi-component exercise programs are recommended for spatial working memory, while VR-based training yields superior outcomes for verbal working memory
A305: The International Communication Path of Table Tennis Sports Presentation
No full textTable tennis carries a unique mission of cross-cultural communication. In 1971, the Ping-Pong Diplomacy with the strategic wisdom of a small ball turning a big ball set a classic model for sports public diplomacy. As a carrier of national cultural symbols, the international communication of table tennis should rely on major events to tell the table tennis story to achieve presentation and Presentation. As a key for event communication, in table tennis events, is driven by the synergy of three-dimensional elements: competitive core + technological extension + commercial drive . Specifically, through the organic combination of visual and auditory elements and the flexible transformation of the field, the cross-cultural communication of table tennis can be carried out more vividly. This paper adopts two research methods. First, by comparing the sports presentation announcement scripts of major table tennis events in the past five years, we analyze them from three aspects: text content, discourse form, and discourse interaction. In addition, we randomly selected 100 viewers of major table tennis events for a questionnaire survey, focusing on: 1. the sense of ceremony through event lighting design, 2. The increase of immersion through the creation of event fields 3. The event information dissemination through bilingual broadcasting 4. The display of athletes\u27 styles in event 5. The cultural performances are interspersed in events on cultural communication. Through the survey, it was found that the ritual empowerment of lighting design, the event spotlight system and dynamic score effects significantly enhance the sense of ceremony, and 78% of the respondents believe that lighting changes can effectively enhance the immersion of watching the game; multi-modal spatial narrative, large screens and mobile camera positions increase the density of visual focus, especially in mixed doubles events across countriesulti-dimensional perspectives significantly enhance cultural dialogue. Conclusion/ Discussion: There are multiple bottlenecks in the international dissemination of table tennis events. At the channel level, there is a reliance on traditional media, with insufficient development of emerging platforms such as short videos and the metaverse, which limits audience coverage. In terms of content production, there is an emphasis on competitive results, lacking cultural symbols. The application of technology and the interaction design show a one-way communication feature. In international communication, table tennis will serve as an important carrier for cultural exchange, promoting cultural dialogue and interaction among different countries and regions
