A036: “the Champion Gene” ACTN3 and Cold Adaptation: An Environmental Regression Model and Systematic Review
No full textThe ACTN3 R577X (rs1815739) genetic polymorphism is a significant research topic in sports genetics, with the XX genotype exhibiting a marked geographical gradient in different populations worldwide. The frequency of the XX genotype is notably higher in cold, high-latitude regions compared to tropical areas (e.g., Sweden 25%, Russia 14.2%, while Kenya 1%). These phenomena suggest that the ACTN3 R577X polymorphism may be closely related to cold adaptation. This study aims to analyze the evolutionary mechanisms, molecular regulation, and potential application of the ACTN3 R577X polymorphism in winter sports talent selection. Using the genomic database Ensemble and the WWF terrestrial ecoregion database, the distribution characteristics of ACTN3 R577X genotypes in different latitudes and temperature conditions were systematically analyzed. Linear regression analysis was employed to explore the relationship between these genotypes and cold adaptation phenotypes. Specifically, the relationships between average latitude, average temperature, and XX genotype frequency were studied. A systematic review of the potential thermogenic mechanisms of ACTN3 polymorphism was conducted based on the terms “ACTN3,” “cold tolerance,” and “cold adaptation.” Linear regression analysis showed a significant negative correlation between average latitude and temperature, with a 1-degree increase in latitude a 0.387°C decrease in temperature (R² = 0.8632). A positive correlation was found between latitude and XX genotype frequency, where each 1-degree increase in latitude resulted in a 0.307% increase in XX frequency (p = 0.00565, R²² = 0.402). These findings suggest a link between the ACTN3 R577X polymorphism and cold adaptation. Molecular studies indicate that ACTN3 deficiency promotes slow muscle fibers and activates mitochondrial biogenesis via calcium signaling, improving energy metabolism and cold tolerance. The ACTN3 XX genotype may offer a physiological advantage in cold environments by improving muscle metabolic efficiency and thermogenesis. Linear regression results confirm the correlation between latitude, temperature, and XX genotype frequency, suggesting a genetic basis for winter sports talent selection. Despite debates on genetic drift in cold adaptation, the high frequency of this genotype in high-latitude cold regions supports the cold adaptation hypothesis. Future research should explore interactions between ACTN3 and other genes (e.g., TRPM8, CPT1A) alongside environmental factors for a more comprehensive approach to talent selection
A290: Multi-Omics Data Fusion-Driven Predictive Model of Exercise Load, Metabolite Profiles, and Cardiovascular Effects
No full textThis study aims to construct a predictive model that integrates multi-omics data, including metabolomics, transcriptomics, and clinical exercise metrics, to elucidate the causal relationships between exercise load, dynamic metabolite profiles, and cardiovascular outcomes. This research addresses the existing knowledge gap in the optimization of personalized exercise prescriptions for metabolic and cardiovascular diseases. A longitudinal cohort of 500 participants underwent cardiopulmonary exercise testing (CPET) alongside blood metabolomics profiling, utilizing targeted lipid and amino acid panels at rest, at the anaerobic threshold, and at peak exercise. The multi-omics fusion approach included: (1) LASSO regression to identify exercise-responsive metabolites (e.g., succinate, β-hydroxybutyrate); (2) Mendelian randomization to validate causal pathways between metabolites and cardiovascular disease (e.g., branched-chain amino acids and endothelial dysfunction); and (3) graph neural networks (GNNs) to integrate metabolic pathways (e.g., PPAR/AMPK), transcriptomic signatures (e.g., PGC-1α), and echocardiographic indices (e.g., left ventricular ejection fraction, CAVI). Cross-species validation was conducted using ApoE−/− mice subjected to exercise preconditioning. The GNN model demonstrated superior predictive accuracy for cardiovascular risk stratification, achieving an area under the curve (AUC) of 0.92, compared to Framingham scores, which yielded an AUC of 0.76. Key findings include: (1) Exercise-induced elevation of β-hydroxybutyrate (β-HB) mediated 38% of the improvement in cardiac output through inhibition of HDAC3 (p \u3c 0.001); (2) High-intensity interval training (HIIT) activated a conserved PPARα-CPT1 axis, which contributed to a reduction in atherosclerotic plaque instability (odds ratio = 0.62, 95% confidence interval: 0.51–0.74); and (3) The temporal dynamics of metabolites measured from 0 to 24 hours post-exercise outperformed single timepoint assessments in predicting endothelial function (ΔR² = 0.21). This multi-omics framework pioneers causal inference in exercise medicine, identifying β-hydroxybutyrate and the PPARα-CPT1 axis as dual targets for cardiovascular disease prevention. It facilitates precision exercise dosing by quantifying metabolic reprogramming thresholds, thereby supporting clinical guidelines for the management of metabolic syndrome. Future research should focus on validating these thresholds in diabetic cohorts through proteomic-epigenomic integration
A090: Development and Efficacy Evaluation of Virtual Reality (VR)-Based Personalized Exercise Prescriptions for Perimenopausal Women
No full textPerimenopausal women (aged 45–54) frequently experience climacteric symptoms such as vasomotor disturbances, osteoporosis, and cardiovascular risks due to declining ovarian function and estrogen levels. Approximately 75% of women report varying degrees of discomfort, with 80% exhibiting at least one symptom (e.g., sleep disorders, mood fluctuations). Conventional exercise prescriptions often lack specificity to address individual health disparities and comorbidities (e.g., osteoporosis, metabolic dysfunction). This study aimed to develop a virtual reality (VR)-based personalized exercise prescription system to enhance exercise adherence through immersive experiences and evaluate its efficacy in alleviating perimenopausal physiological and psychological symptoms. A personalized exercise prescription generation system was developed by integrating health assessments (body composition, cardiopulmonary function, bone mineral density) with VR technology. The system dynamically adjusted exercise regimens (e.g., moderate-intensity aerobic and resistance training) based on biosensor data (heart rate, exercise intensity) and user preferences. A total of 120 perimenopausal women were randomly assigned to either a VR intervention group (VR-guided personalized exercise) or a control group (conventional exercise guidance) for a 12-week intervention. Outcome measures included physiological indices (estradiol levels, bone mineral density, heart rate variability [HRV]), psychological scales (anxiety/depression scores), and exercise adherence, quantified via accelerometry and clinical tests. The VR group demonstrated significantly greater improvements in vasomotor symptom frequency (42% reduction vs. 28%, p \u3c 0.05), sleep quality (35% decrease in Pittsburgh Sleep Quality Index scores), and balance capacity (22% increase in Berg Balance Scale scores) compared to the control group. Superior outcomes were also observed in bone mineral density (femoral neck T-score: +0.8% vs. +0.3%) and HRV parameters (18% increase in RMSSD). Psychologically, anxiety scores decreased by 40% in the VR group, with adherence rates reaching 85% (vs. 62% in controls). Biomechanical analysis revealed that VR-enhanced real-time feedback improved movement precision and reduced joint stress during exercise. VR technology effectively improves exercise engagement and mitigates perimenopausal symptoms through personalized, gamified interventions. Its strengths lie in dynamic adaptation to individual health profiles (e.g., osteoporosis risk) and multimodal feedback to ensure exercise safety. Future studies should expand sample sizes to validate long-term efficacy and explore deeper integration of VR with wearable devices for real-time health monitoring and prescription optimization. This study provides an innovative approach to perimenopausal health management, highlighting the potential of immersive technologies in addressing sex-specific health challenges

Traditional sports enhance physical fitness, balance, flexibility, and psychological well-being. 2. Educational integration fosters active ICH transmission and cultural identity 3. AI-assisted learning, motion tracking, and VR improve training accessibility and engagement. Ethnic traditional sports bridge cultural heritage and modern health promotion, but face challenges such as standardization and policy support. A culture-health dual-track strategy is proposed: 1) Policy Recommendations: Integrate ethnic sports into national exercise prescription systems. 2) Educational Integration: Expand school-based programs for dynamic ICH transmission. 3) Technological Advancement: Leverage AI and VR for modernization and accessibility
A235: The Impact of Psychological Skills Training on the Sports Performance of Adolescent Athletes: A Systematic Review
No full textPsychological skills training, as an essential component of competitive sports training, is currently a popular method widely applied to enhance athletes’ performance. Particularly for adolescent athletes, psychological training not only helps them perform at their best in competitive settings but also promotes the comprehensive development of their psychological qualities. However, current research primarily focuses on adult populations, and studies targeting adolescents still have certain limitations. This article aims to review the impact of psychological skills training on the sports performance of adolescent athletes by analyzing the content, methods, and findings of existing research. It summarizes the shortcomings of current studies and provides suggestions for future research. Method: Using keywords such as “Psychological Skills Training”, “ports performance”, and “adolescent athletes”, we searched multiple databases such as China National Knowledge Infrastructure, Wanfang Database Full Text in November 2024. Different psychological skills training methods play a significant and positive role in enhancing the competitive performance of adolescent athletes, strengthening their psychological resilience, improving their team collaboration abilities, and reducing competition-related anxiety and tension. Currently, most research on psychological interventions in competitive sports suffers from issues of selection bias. Additionally, psychological intervention experiments often struggle to achieve complete blinding, as participants may be aware that they are receiving interventions. Due to the limited number of specific athletes, study sample sizes are typically small. If larger-scale samples could be used, more compelling conclusions might be drawn. On the other hand, there is still a scarcity of research on the specific mechanisms through which these interventions work. Therefore, it is necessary to strengthen the measurement and exploration of psychological variables to gain a deeper understanding of the psychological processes underlying intervention effects. This would further distinguish the effects of different interventions, enabling more targeted implementation of relevant interventions. Moreover, most studies focus on measuring short-term effects post-intervention, lacking systematic research on the long-term impacts on adolescent athletes. Additionally, individual differences are often not fully considered. Factors such as personality, psychological developmental stage, and cultural background of adolescent athletes may influence the effectiveness of psychological training, yet current research rarely delves into these aspects
A172: Research History, Hotspots, and Trends of Triathlon in China
No full textIn the 80s of the 20th century, triathlon was widely spread after it was introduced to China. Over the years, with the development of scientific sports training and national fitness, China\u27s triathlon research has gradually attracted attention, and its research involves sports science, medicine, psychology, and mechanical engineering. Therefore, to promote the sustainable development of triathlon in China, this study reviews the history, hotspots, and trends of triathlon research in the past, and provides a theoretical reference for subsequent research. The data in this study were obtained from the China National Knowledge Infrastructure (CNKI) database. A total of 263 relevant research articles were retrieved and screened by keywords such as Triathlon , Triathlete , and Triathlon Event . These documents are uploaded to the CiteSpace software to generate research maps. Based on these maps, this study analyzes the co-occurrence and clustering of keywords and reveals the research hotspots and trends in the field of triathlon. China\u27s research on triathlon began in 1989 and has shown fluctuating growth since 2004, with four significant growth periods in 2007, 2010, 2015, and 2020. The research mainly focuses on three categories: special training, scientific monitoring, and the event industry, and high-frequency keywords include triathlon , athlete , training , altitude training , sports events , youth , physical fitness , and swimming . The most cited literature includes applied research on special training, event development, and scientific monitoring, and representative studies have explored altitude training methods, physical fitness characteristics of elite athletes, and the organization and management of events. In recent years, emerging research hotspots include physical fitness , sports events , and adolescents . The research shows that the research on triathlon in China fluctuates greatly, lacks breadth and depth, and the research hotspots are scattered. Among them, compared with scientific monitoring and event industry research, special training research attaches more importance to it, and applied research dominates. In the past five years, sports events, physical fitness, and youth-related aspects have become major research hotspots. To promote the development of this field, it is suggested that future research should break through the limitations of the field, integrate new interdisciplinary theories and methods, and deepen the research on training, monitoring, and competitions. In addition, it should also follow the trend of digitalization and intelligence and focus on the selection and training of young athletes, laying the foundation for the long-term development of triathlon

A071: Multidimensional Impact of Picturebooks on Preschoolers\u27 Physical Literacy via Educational Intervention
No full textTo explore the role of picturebooks as educational interventions in promoting the development of physical literacy in preschoolers aged 3-6 years old, and to analyze effectiveness in enhancing children\u27s body perception, fundamental movement skills and awareness of healthy behaviors through content design, interactive reading and activity extension, in order to provide a theoretical basis for the practice of physical literacy in early education. Method: Using a randomized controlled experimental design, 256 preschoolers were selected and divided into an experimental group (n=128) and a control group (n=128). The experimental group conducted dynamic reading activities (e.g., movement imitation, situational play, and role-playing) based on the Movement Stories Series and Health Theme Picturebooks for 30 minutes, three times a week, while the control group conducted regular reading sessions. Physical literacy levels were assessed after the intervention using the Physical Literacy in Children Questionnaire (PL-C Quest), and inter- and intra-group differences were analyzed by independent and paired samples t-tests. (1) Before the experiment, there was no significant difference between the physical literacy levels of the children in both groups (p \u3e 0.05); (2) After the experiment, the experimental group had a highly significant difference between the physical and cognitive domains (p \u3c 0.01), and the psychological and social domains (p \u3c 0.05); the children in the control group had a significant difference only in the cognitive domain (p \u3c 0.05), and there was no significant difference in the domains (p \u3e 0.05). Picture books can effectively stimulate preschoolers\u27 interest in participating in physical activities and promote overall development of physical literacy through visualization scenes, character demonstrations, and dynamic interactive practices. It is recommended that picture books and physical activities be integrated into a structured educational program, that families and kindergartens work together to create a dynamic reading environment, and that the creation of picture books be guided to incorporate the themes of sports science and health in order to support children\u27s physical literacy development

(2) College students were positive and optimistic after taking part in aerobics. Whether in competitions or performances, students needed to overcome the feelings of nervousness and shyness. And as their skills improved, students would gradually become confident and composed, which helped them to develop positive psychological qualities such as being strong, optimistic, and positive. (1) Under the 5E teaching model, students\u27 aerobic skills and positive psychological qualities improved. (2) Approaches to cultivating students\u27 abilities in the aerobics elective course under the 5E teaching model: Cultivate students\u27 self-confidence, enhance their own charm and positive psychological qualities, and be brave in solving problems and overcoming difficulties; Adopt a variety of teaching methods and practical ways to strengthen students\u27 learning experience at various stages as well as the practice of basic physical fitness; Cultivate students\u27 ability to study independently and solve problems
A019: The Effects of Badminton Exercise on Body Composition and Physical Fitness in Female College Students
No full textWith the increasing focus on health and the widespread participation in physical activities, badminton has become a popular sport due to its accessibility and benefits. It improves physical fitness, cardiovascular functions, flexibility, and coordination. Particularly among female college students, it offers both recreational enjoyment and a means to enhance physical and mental well-being. This study investigates the effects of badminton on body composition and physical fitness among female college students, providing insights into its potential application in physical education. A total of 50 female sophomore students from H University, aged 20.8±1.6 years, were selected as participants. None had prior professional training in badminton. The intervention consisted of a 90-minute badminton class twice a week for three months. Pre- and post-intervention tests were conducted to evaluate changes in body composition (height, weight, BMI, WHR) and physical fitness indicators, including muscular strength (grip strength, back strength), endurance (sit-ups), flexibility (sit-and-reach), and cardiopulmonary function (resting heart rate, vital capacity, 1-second rate, MVV). Data were analyzed using paired t-tests with significance set at p \u3c 0.05. Post-intervention results revealed significant improvements in WHR (p \u3c 0.05), muscular strength (grip strength and back strength, p \u3c 0.05), endurance (sit-ups, p \u3c 0.05), and flexibility (sit-and-reach, p \u3c 0.05). Cardiopulmonary function indicators also improved significantly, including a decrease in resting heart rate and increases in vital capacity, 1-second rate, and MVV (p \u3c 0.05). However, no significant changes were observed in BMI, height, or weight. This study demonstrates that badminton has significant effects on improving physical fitness and cardiopulmonary function in female college students, particularly in terms of enhancing muscular strength, flexibility, and endurance. As a full-body aerobic activity, badminton effectively stimulates multiple muscle groups and promotes overall fitness. The observed improvements in cardiopulmonary indicators, such as reduced resting heart rate and increased vital capacity, 1-second rate, and maximum voluntary ventilation, suggest that badminton contributes to better cardiac efficiency and pulmonary function. However, the findings also reveal limited impact on overall body composition, as no significant changes were observed in BMI, height, or weight. This may be attributed to the relatively short intervention period and the participants’ healthy baseline characteristics. Future studies should explore the long-term effects of badminton training, incorporate diverse participant profiles, and refine training protocols to maximize benefits
