A292: From Single to Multifunctional: Synergistic Pathways and Insights into Sports Venue Renovation and Urban Planning
No full textThe functional renovation of sports venues is a critical component of urban planning and plays a significant role in promoting sustainable urban development. As urbanization accelerates, traditional sports venues, limited by their single-function design, struggle to meet the diverse demands for public fitness, cultural activities, and commercial services. This study focuses on multiple sports venues in Guangzhou and Shantou, Guangdong Province, aiming to clarify the coordinated logic between venue renovation and urban planning. It aims to construct a dynamic adaptive strategy framework to provide theoretical support for enhancing urban spatial efficiency and improving residents\u27 quality of life. This study employs a mixed-methods approach that combines literature review, case studies, and empirical investigations. The research subjects include Tianhe Sports Center and Guangdong Olympic Sports Center in Guangzhou, as well as Shantou Sports Center. By analyzing policy documents, academic literature, and field data on venue utilization, surrounding transportation, and commercial distribution, the study combines qualitative analysis with logical reasoning to propose coordinated development strategies. The study identifies several challenges in venue renovation, including ambiguous functional positioning, spatial disconnection from urban layouts, outdated facilities, and rigid operational mechanisms. Addressing these challenges through strategies such as aligning functional positioning with urban planning, integrating spatial layouts with urban functions, coordinating facility upgrades with technological advancements, and establishing multi-stakeholder collaboration mechanisms can significantly enhance venue utilization and economic efficiency. Field surveys demonstrate that renovations in Guangzhou and Shantou have driven regional economic growth, optimized urban spatial structures, improved cultural and sports facilities for citizens, and promoted social equity. The proposed coordinated strategies provide a solid theoretical foundation for addressing the conflict between the limited functions of sports venues and the diverse needs of urban development. Unlike previous studies, this research emphasizes the systematic integration of venue functions with urban planning and highlights the importance of multi-stakeholder collaboration. A limitation of this study is the lack of quantitative analysis; future research could employ big data techniques to further validate the feasibility of the proposed strategies. Practically, this offers actionable insights for the sustainable development of sports venues and fosters deeper integration of the sports industry with urban planning, contributing to the creation of smarter and more inclusive urban ecosystems
A233: Digital Empowerment and Governance Innovation for Smart Sports Community Development in Urban China
No full textSmart sports communities are emerging as a crucial component of China’s National Fitness Strategy, driven by digital empowerment and governance innovation. This study examines the historical evolution of urban community sports and investigates how technological innovations enhance governance, management, service efficiency, and user experience in the development of smart sports communities. Method: This research employs an empirical case study in the Yangtze River Delta region, encompassing 25 grassroots communities across cities such as Nanjing, Jiaxing, Shanghai, Hefei, and Wuhu. A historical analysis of policy documents, academic research, and media reports provides longitudinal insights into the transformation of urban community sports since the 1990s. In addition, qualitative data were collected through in-depth interviews with key stakeholders (government officials, citizens, volunteers, suppliers, and project managers) and field observations, assessing the role of digital technologies in fostering sports participation and enhancing governance effectiveness. The findings indicate that digital empowerment and governance innovation are reshaping smart sports communities in multiple ways: (1) shifting community sports services from a government-led model to a public-private partnership approach that responds to personalized demands; (2) optimizing grassroots governance through digital platforms and smart applications, enabling refined management of public services; (3) reinforcing national policy implementation and regulatory oversight via smart service technologies; and (4) fostering community engagement, social collaboration, and sustainable urban development by integrating digital tools into sports participation frameworks. The integration of technological innovation into community sports governance provides new opportunities for urban community development, enhancing both participation and management efficiency. However, this study also identifies challenges related to technology alienation. Future development of smart sports communities should move beyond infrastructure deployment to emphasize dynamic, multi-stakeholder collaboration, the construction of interactive online-to-offline sports networks, and the expansion of public social spaces. Simultaneously, governance strategies should address potential risks of technology alienation to ensure inclusive and balanced development in the digital era
A261: Association Between Motor Coordination Skills and Emotional-Behavioral Problems in 3–6-Year-Old Children
No full textThe development of motor coordination between the ages of 3 and 6 is a critical time for children. Good motor coordination not only serves as the foundation for children\u27s daily activities but also promotes the maturation of neural development, thereby facilitating the growth of their language, intelligence, and emotional abilities. Developmental coordination disorder (DCD) is a disease characterized by significantly impaired motor coordination. Children at risk for DCD (rDCD) often have emotional and behavioral problems that can negatively affect long-term outcomes. The purpose of this study was to compare the differences in emotional-behavioral problems between children with rDCD and typically developing (TD) children, and to explore the correlation between motor coordination skills and emotional-behavioral problems. Thirty-nine children with rDCD were selected from a children\u27s hospital, and 31 children with TD were examined at the same time: according to age, 0.5 years. were selected as controls. The Movement Assessment Battery for Children, Second Edition (MABC-2) was used to assess the motor coordination of the children, and the Strengths and Difficulties Questionnaire (Parent version) (SDQ) was used to assess the emotional and behavioral problems of the children. The Mann-Whitney U test was used to compare the differences between the two groups in terms of emotional symptoms, conduct problems, hyperactivity, peer interaction problems, and pro-social behaviors. Partial correlation and ordered logistic regression were used to analyze the relationship between motor coordination skills and emotional-behavioral problems. The age of the children was (4.97 ± 0.84) years old. The differences in peer interaction problems and pro-social behaviors between TD and rDCD children were statistically significant (P \u3c 0.05). Partial correlation analysis showed that motor coordination ability was closely related to peer interaction problems and pro-social behavior (P \u3c 0.05). Regression results showed that motor coordination deficits in children increased the risk of peer interaction problems (OR: 3.87, 95% CI: 1.52-9.84) and pro-social behavior (OR: 13.75, 95% CI: 2.89-64.75). This study indicates that there is a correlation between children\u27s motor coordination skills and emotional-behavioral problems. Children with rDCD perform poorly in peer interaction and pro-social behavior. Therefore, it is very important to screen children\u27s motor coordination skills at an early stage. When intervening with children with rDCD, attention should be paid to their emotional and behavioral problems

A021: Analysis of the Impact of Ski Diagonal Stride Technique on Rehabilitation Treatment Effects
No full textThe ski diagonal stride technique is a crucial component in cross-country skiing, engaging complex muscle coordination, enhancing cardiopulmonary function, and improving balance. In the realm of rehabilitation, traditional methods often face limitations. This study is dedicated to exploring how the physiological factors associated with this technique affect the rehabilitation treatment outcomes. By doing so, it aims to optimize rehabilitation strategies and ultimately enhance patients\u27 physical capabilities and quality of life. Method: Eighty patients between the ages of 30 and 60, all in need of lower-limb rehabilitation, were evenly distributed into an experimental group and a control group. The experiment was carried out in a specialized rehabilitation institution. Over 16 weeks, the experimental group underwent training centered around the ski diagonal stride technique. Starting with simple movements, the training gradually advanced to simulate more challenging diagonal stride situations. They trained 5 times a week, with each session lasting 45 minutes. Meanwhile, the control group adhered to traditional lower-limb rehabilitation training. To accurately assess the effects, surface electromyography instruments, cardiopulmonary function monitors, and balance testing devices were employed. Data were collected at the beginning of the training, after 8 weeks, and at the end of the 16 - week then analyzed using SPSS software. After 16 weeks of training, the experimental group exhibited significant improvements. The maximum isometric contraction force of key muscles, such as the quadriceps femoris, increased by 40%, compared to a 20% increase in the control group. Muscle fatigue was delayed by approximately 30% in the experimental group, while the control group showed only a minor improvement. The experimental group also experienced a 15% increase in maximum oxygen uptake, with more notable improvements in ventilation efficiency compared to the control group. Additionally, the single-leg standing time and the scores of the closed-eye balance test in the experimental group increased by 35% and 40% respectively, contrasted with 15% and 20% in the control group. All these differences between the two groups were highly significant (p \u3c 0.01). The findings indicate that the ski diagonal stride technique is more effective in rehabilitation treatment than traditional methods. However, this study has its limitations, including a relatively small sample size and a short observation period. Future research could address these issues by increasing the sample size and prolonging the observation time. This research provides rehabilitation professionals with new perspectives for treatment optimization
A157: Research on Yunnan Outdoor Sports Industry Policy Texts Under the Policy Instrument Perspective
No full textOutdoor sports serve as both a key vehicle for meeting the public\u27s diversified fitness needs and a crucial link in promoting the deep integration of sports and tourism. In recent years, China\u27s outdoor sports industry has flourished, with Yunnan Province achieving remarkable progress in its high-quality development. This success stems from Yunnan\u27s unique natural resource endowment and institutional guarantees formed through local governments\u27 targeted policy measures. Grounded in policy instrument theory, this study constructs an analytical framework to systematically analyze outdoor sports industry policies issued by Yunnan provincial authorities since November 2022. The research aims to provide theoretical references for optimizing provincial policy supply and improving policy instrument systems, while offering practical insights for other provinces in constructing their outdoor sports industry policy frameworks. Method: Using keywords such as “outdoor sports” and “sports industry , I searched several official websites of Yunnan provincial government departments to collect relevant documents. A dual-dimensional X-Y analytical framework was constructed, integrating policy instruments and policy target groups. For the policy instrument dimension, Rothwell\u27s theory was adopted, categorizing instruments into supply-side, demand-side, and environmental. The policy target groups’ dimension classified stakeholders into four groups: government agencies, social organizations, enterprises, and citizens. The policy texts were coded using NVivo14 according to the analytical framework, with subsequent systematic analysis conducted on the coded results. Result: This study identified six valid policy documents, including two specific policies and four related policies. In terms of policy instruments, there exists a structural imbalance among the three categories: supply-oriented instruments predominate with the highest application frequency, followed closely by environment-oriented instruments, while demand-oriented instruments show evident underutilization. Regarding policy target objects, government-related provisions constitute over half of the total, securing a dominant position. Enterprise-oriented clauses rank second in proportion, whereas content concerning social organizations and the public remains notably scarce, exhibiting a significant disparity compared to governmental and corporate provisions. In terms of policy instruments, Yunnan\u27s outdoor sports industry policies exhibit a supply-side emphasis, environmental stabilization, weak demand-side support pattern. This likely stems from the industry\u27s underdeveloped external environment requiring policy guidance to channel resources, while future efforts should strengthen demand-side policy design to achieve balanced industrial development. In terms of target groups, the government dominates as the primary, likely due to Yunnan\u27s outdoor sports industry being in its developmental phase. Future policies should balance stakeholder interests to establish a comprehensive and balanced policy framework across all sectors
A056: Comparative Effectiveness of Exercise Modalities on Cognitive Function in Parkinson\u27s Disease: A Network Meta-Analysis
No full textBackground/Objectives: Parkinson\u27s disease (PD) is a progressive neurodegenerative disorder often associated with cognitive decline, particularly executive dysfunction. Various exercise interventions have been explored to mitigate cognitive impairment in PD, but a comprehensive comparison of exercise modalities has yet to be conducted. This study aims to systematically evaluate the effectiveness of different exercise types in improving cognitive function, including global cognition and executive function, in patients with PD through a network meta-analysis of randomized controlled trials (RCTs). This systematic review and network meta-analysis adhered to PRISMA 2020 guidelines. Electronic searches were conducted in PubMed, Medline, Embase, Cochrane, and Web of Science until December 31, 2024. Eligible studies included RCTs involving adults with PD, comparing any form of exercise with no intervention or usual care, and reporting cognitive outcomes. A network meta-analysis was performed using random-effects models to compare the relative effects of interventions on cognitive outcomes, measured by standardized mean differences (SMDs) for global cognition and executive function. Forty RCTs involving 1582 PD patients were included. Motor-cognitive training (MCT) was the most effective modality for improving both global cognition (SMD = 1.77, 95% CI 0.60–2.95) and executive function (SMD = 0.97, 95% CI 0.14–1.81), with the highest probability of ranking first in both cognitive domains (SUCRA = 94.9% for global cognition, 85.3% for executive function). Aerobic exercise (AE) also significantly improved global cognition (SMD = 0.66, 95% CI 0.02–1.30) and executive function (SMD = 0.65, 95% CI 0.18–1.12), while Tai Chi and stretching/flexibility training (SFT) showed benefits for global cognition but limited effects on executive function. This analysis highlights MCT and AE as the most effective interventions for enhancing cognitive function in PD. MCT offers the greatest benefits across multiple cognitive domains, while AE provides a more accessible alternative with substantial cognitive improvements. Tai Chi and SFT may enhance global cognition but are less effective for executive function. These findings suggest that exercise interventions can be tailored to improve specific cognitive outcomes in PD, and future studies should focus on standardized protocols and long-term outcomes to refine treatment recommendations
A162: Anta’s Business Model Innovation Empowers New Productive Forces in the Sports Industry
No full textJustin Yifu Lin identifies new quality productive forces that drive China\u27s sports sector upgrading and requires sports enterprises to embrace the Smiling Curve through brand innovation and digital integration, which requires business model innovation. ANTA\u27s business model innovation effectively exemplifies the transition towards high-value-added segments at both ends of the Smiling Curve . Despite economic downturn and intense intra-industry competition, ANTA has achieved remarkable performance through four distinct phases of business model transformation, which can offer practical insights for other domestic sports enterprises and foster new productive forces in China’s sports industry. Method: This research adopts documentary research and comparative case analysis with Anta Sports as the longitudinal research subject. The article also uses the comparative analysis method, choosing Li Ning as the main comparison enterprise. At present, Li Ning has taken over Anta as the official sportswear partner of the Chinese national team, and Anta\u27s experience is crucial to Li Ning. Utilizing the theoretical framework of the Wei-Zhu Six-Element Business Model, the study systematically examines the evolutionary trajectory of business model innovation in sportswear enterprises during digital transformation. This article analyzes Anta\u27s positioning of single focus, multi-brand, globalization , the business system of brand + retail facing consumers, the pursuit of healthy cash flow structure, irreplaceable key resource capabilities, the profit model of DTC, e-commerce, traditional wholesale and other , and the enterprise value of the leader of China\u27s sporting goods industry”. These six business model elements show that Anta Sports\u27 business model innovation has laid a solid foundation for its ranking first in China\u27s sporting goods enterprises. However, some issues persist, including over-reliance on the domestic market, neglect of offline channels in smaller cities, and insufficient R&D investment leading to product homogenization. This study proposes that Anta should: (1) accelerate internationalization through diversified market penetration strategies to expand global operations; (2) construct an integrated channel network by enhancing physical retail experiences and optimizing omnichannel operational synergies; (3) execute an innovation-driven strategy with increased R&D investment to establish technological barriers and strengthen market competitiveness through product differentiation. The conclusions aim to provide valuable references for domestic sports goods manufacturers undergoing or preparing for transformation, offering insights to address industrial transition challenges and enhance core competitiveness
A278: The Effects of MTM-Based Stepped Behavior Change Intervention on Sedentary Lifestyle Among Community-Dwelling Older Adults
No full textSedentary lifestyles are prevalent in the life patterns of community-dwelling older adults, who have been shown to be the most sedentary and physically inactive subgroup. Prolonged low energy expenditure during waking hours leads to an increased risk of non-communicable diseases and impairs physical functioning in older adults, negatively impacting their health outcomes. Therefore, interventions targeting changes in sedentary lifestyles are necessary to improve health behaviors in older adults. An experimental study was conducted to verify whether a sedentary lifestyle modification intervention based on the Multi-Theory Mode（MTM）and the staircase approach is more effective than conventional education in reducing sedentary time and improving physical activity levels, physical function, and quality of life among community-dwelling older people. Method: This trial was a multicenter, assessor-blinded, 18-week, two-arm, parallel-group, randomized controlled trial. Study participants were recruited from May to August 2024 at two community health centers in Changchun, China. A total of 60 community-dwelling older adults with sedentary lifestyles (sedentary and physically inactive) were randomly assigned to the intervention and control groups. Participants in the intervention group received an MTM-based stepped sedentary lifestyle change intervention involving three thematic sessions (biweekly) and two telephone follow-up visits. The session topics were organized in a stepped manner with a rhythm of “Sedentary behavior↓→LPA↑→MVPA↑”. Participants in the control group received the usual care. Endpoints were collected at baseline, week 6, week 12, and week 18. The primary endpoint is the change in self-reported sedentary time. Secondary endpoints include the changes in screen-based sedentary time, sedentary behavior characteristics, step count (pedometer-measured), time spent in LPA and MVPA, SPPB score, anthropometric parameters, blood pressure, and SF-12 score. Of the 60 randomized participants (70.2 ±4.3 years; 46 men [76.66%]), 51 completed outcome measurements at the four time points. Compared with the control group, participants in the intervention group showed a significant reduction(difference [95% CI]) in sedentary time (-81.8min [-130.570 to -33.135]), screen-based sedentary time (-48.4min [-88.6 to -8.1]), and longest continuous sedentary time (-40.6min [-64.3 to -16.8]) were significantly reduced; Weekly MVPA time ( 93.0min [59.0 to 126.9]), step count (2427.8step [23.0 to 4832.4]), SPPB score (0.9 [ 0.1 to 1.8])were significantly improved. Compared with conventional nursing, the MTM-based staircase approach behavior change intervention can significantly reduce sedentary behavior, increase physical activity level, promote physical function, and maintain the health-related quality of life of older adults
A152: Effect of Stroboscopic Visual Perturbation on Posture Control in Patients with Chronic Ankle Instability
No full textChronic ankle instability (CAI) is a common sports injury, often accompanied by reduced proprioception, muscle weakness, and impaired balance. Its etiology is often attributed to inadequate rehabilitation following initial ankle sprains, resulting in ligament laxity or damage. This study aimed to investigate whether stroboscopic visual disturbance influences static and dynamic postural control in individuals with CAI, thereby exploring the relationship between visual input and postural stability. Method: Thirty college students with unilateral CAI (9 males, 21 females; age: 21.3±1.2 years, height: 168.1±9.8 cm, weight: 63.5±11.6 kg) were recruited. Their static and dynamic postural control was measured in three conditions: eyes open (EO), eyes closed (EC), and stroboscopic vision (SV). Static postural stability was measured during single-leg standing and represented by maximum displacement of the plantar center of pressure (COP), average velocity in anteroposterior (AP) and mediolateral (ML) directions of COP. Dynamic postural stability was measured during the Y-balance, represented by the relative reach distance. One-way repeated measures ANOVA was conducted on the variables of interest to assess the main effect of visual conditions. For the Y Balance Test, significant reductions were observed under SV compared to EO conditions in anterior reach (EO: 0.68 ± 0.83 vs. SV: 0.62 ± 0.60, p \u3c 0.05), posteromedial reach (EO: 1.04 ± 0.91 vs. SV: 0.96 ± 0.97, p \u3c 0.05), posterolateral reach (EO: 1.10 ± 0.82 vs. SV: 1.02 ± 0.86, p \u3c 0.05), and composite scores (EO: 0.94 ± 0.72 vs. SV: 0.87 ± 0.70, p \u3c 0.05). For static postural control, COP maximum displacement and average velocity in the AP and ML directions exhibited significant differences between SV and EC conditions compared to EO (p \u3c 0.05), though no significant differences were observed between SV and EC. Stroboscopic visual perturbation significantly compromised postural control in individuals with CAI. These results indicate that visual perturbation heightens injury risks in individuals with CAI, highlighting the necessity for targeted interventions addressing the visual system within rehabilitation programs
