A118: Hypoxic Exercise Suppresses KHK Gene to Improve Cardiac Function on a High Fructose Diet
No full textUp-regulation of KHK activation on a high fructose diet is positively associated with the subsequent development of several metabolic diseases, including high fructose diet-induced heart disease. Hypoxic exercise is considered an effective means of treating and preventing metabolic diseases and improving cardiac function. However, it is unclear whether the link between hypoxic exercise and high fructose-induced heart disease exists. Therefore, the aim of this study was to investigate the link between the modulation of KHK by hypoxic exercise and high fructose diet heart disease. Method: Three hundred virgin flies of the wild-type W1118 strain were collected and randomly assigned to control (NC), high fructose diet (HF), and high fructose diet (HE) groups, with 100 flies’ group. Drosophila on a high fructose diet were fed continuously with high fructose from birth to 12 days old, and Drosophila on hypoxic exercise were fed with a self-developed hypoxic exercise device for 5 consecutive days of 1 hour per day from 7 days old, and each group was sampled at 13 days old. Changes in KHK expression levels in the heart were detected by RT-qPCR, and various kinds of Drosophila cardiac function were quantified using an EM-CCD digital camera and semi-automatic optical heartbeat analysis software. Compared with the NC group, KHK mRNA expression was increased (P \u3c 0.05), arrhythmia index was increased (P \u3c 0.05), systolic intervals (P \u3c 0.01), diastolic intervals were bradycardic, systolic diameter and diastolic diameter were decreased (P \u3c 0.01), and ejection fraction was decreased (P \u3c 0.001) in Drosophila hearts after the high fructose diet; compared with the HF group, in Drosophila hearts of the HE group KHK mRNA expression decreased (P \u3c 0.05), arrhythmia index decreased (P \u3c 0.05), cardiac inter-systolic interval decreased (P \u3c 0.001), diastolic bradycardia improved, systolic diameter increased, diastolic diameter increased (P \u3c 0.05), and ejection fraction increased (P \u3c 0.01) in Drosophila hearts from the HE group. Hypoxic exercise improved cardiac rhythmic function and pumping dysfunction on a high-fructose diet by inhibiting KHK expression in the heart
A048: Design and Application of Motion Capture Analysis System for Sports Intangible Cultural Heritage
No full textAs a core component of China\u27s sports intangible cultural heritage, traditional martial arts face critical challenges in technical transmission, including movement distortion, non-standardized instruction, and cultural semantic loss. Existing motion capture technologies struggle to balance high-dynamic movement precision with cultural context interpretation (e.g., Tai Chi’s waist-hip rotation reflecting Yin-Yang philosophy). This study aims to design a multi-modal motion capture analysis system (MCAS) that integrates optical-inertial-force sensing architectures, culturally weighted algorithms, and real-time feedback mechanisms to resolve occlusion-induced drift errors and preserve both bio-mechanical accuracy and cultural semantics, thereby providing a technical pathway for digital preservation and transmission of martial arts. The study recruited 10 Tai Chi masters and 120 novice learners for three experimental phases in a laboratory setting: Technical validation: Simulated occlusion scenarios compared positioning errors between hybrid (optical+inertial+force) and optical-only systems; Cultural fidelity assessment: A double-blind experimental design evaluated the cultural accuracy of Single Whip movements under three conditions (traditional teaching, standard motion capture, and MCAS) via expert panel scoring; Pedagogical intervention: Learners were randomly assigned to MCAS or traditional groups for a 6-month longitudinal study, tracking skill acquisition speed, dropout rates, and cultural cognition changes. Data collection included kinematic parameters (200 Hz), ground reaction forces, and expert rating scalesanalyzed [sic] using mixed-effects models and thematic analysis for quantitative-qualitative integration. Technical performance: The hybrid system achieved a maximum positioning error of 2.3 mm under occlusion (vs. 8.7 mm for optical-only systems); Cultural preservation: The MCAS group attained 94.3% cultural accuracy (vs. 72.1% in standard and 65.4% in traditional groups), with 89% alignment of waist-hip rotation angles with Yin-Yang philosophy (vs. 54% in standard groups); Educational efficacy: The MCAS group showed 37% faster skill acquisition (p \u3c 0.01), an 8% dropout rate (vs. 23% in traditional groups), and 41% higher cultural cognition scores (p \u3c 0.001). This study pioneers the quantitative integration of cultural semantics into motion analysis algorithms, demonstrating that multi-modal fusion architectures overcome technical limitations of conventional motion capture. Compared to prior work, MCAS enhances data precision while addressing the critical issue of formal resemblance without spiritual fidelity through culturally weighted mechanisms. Limitations include reliance on expert-defined cultural weights, necessitating future AI-driven dynamic optimization. Practically, MCAS provides a replicable digital framework for safeguarding martial arts and other kinetic cultural heritage forms, with adaptable applications in dance, opera, and related domains
A058: The Effects of Isotemporal Reallocation of 24-Hour Activity Behaviors on Physical Fitness in Preschool Children
No full textPreschool children\u27s physical fitness is critical for lifelong health, yet recent trends show declining fitness levels, rising obesity, and reduced physical competence. Physical activity (PA), sedentary behavior (SB), and sleep (SLP) are key lifestyle factors influencing health. Compositional data analysis (CDA) addresses multicollinearity among these behaviors, while the isotemporal substitution model evaluates the effects of reallocating time between them. This study investigates the associations between 24-hour movement behaviors and preschool children\u27s physical fitness, offering evidence-based recommendations. Method: A total of 806 preschool children aged 3–6 years were recruited from three kindergartens in Shanghai using cluster random and convenience sampling. Demographic information (gender, age, parental education, parental attitudes toward physical activity, and BMI) was collected via questionnaires. Physical fitness was assessed using the 2023 National Physical Fitness Assessment Standards, including body morphology and physical abilities. The Actigraph wGT3X-BT accelerometer recorded 24-hour activity behaviors, including moderate-to-vigorous physical activity (MVPA), light physical activity (LPA), SB, and SLP over seven days, with at least three valid days required. Data were processed using ActiLife 6.5 software. Compositional multivariate linear regression and isotemporal substitution models were applied, with isometric log-ratio (ilr) transformations used to address multicollinearity. Statistical analyses were conducted using R 4.3.2 and Stata 17.0. The study included 806 preschool children (432 boys, 374 girls). Boys outperformed girls in grip strength (P \u3c 0.01), while girls excelled in sit-and-reach flexibility (P \u3c 0.01). MVPA was positively associated with overall fitness, grip strength, standing long jump, and flexibility (P \u3c 0.01), but negatively associated with BMI and coordination (P \u3c 0.05). SB and SLP showed inverse associations. Reallocating 15 minutes from LPA, SB, or SLP to MVPA significantly improves fitness, with the greatest improvements observed when replacing LPA (P \u3c 0.05). Specifically, substituting LPA with MVPA grip strength, standing long jump, and flexibility, while replacing SB or SLP with MVPA BMI and coordination. Conversely, reallocating time from MVPA to LPA, SB, or SLP fitness outcomes. This study highlights the link between 24-hour activity behaviors and physical fitness in preschool children, with boys excelling in strength and girls in flexibility. Reallocating time to MVPA, particularly by replacing LPA, SB, or SLP, fitness. Interventions should promote outdoor play, reduce screen time, and consider gender differences. Future research should employ longitudinal designs to establish causality, expand samples to diverse regions, refine activity measurement, and incorporate additional covariates like diet and family environment

A192: Exploration of Social Intervention Mechanisms for Urban Autism Groups Through Ethnic Traditional Sports
No full textDuring urbanization, individuals with urban autism face mental health challenges due to social barriers, while existing social therapies suffer from insufficient cultural adaptability and high participation thresholds. This study employs ethnic traditional sports as a medium to explore the intervention effects of their non-verbal interactive features on the social skills of autism patients, aiming to construct a localized mental health service pathway. Six collective ethnic traditional sports (e.g., the Yi ethnic group’s Dage dance, Mongolian Andai dance) were selected to design a three-stage intervention program: movement imitation—rhythm resonance—emotional connection. Twenty-four adolescent autism patients (aged 12–16; 15 males, 9 females) were recruited and randomly divided into an experimental group (n=12) and a control group (n=12). An 8-week intervention (3 sessions/week, 45 minutes/session) was conducted. Mixed methods were applied: quantitative analysis of social behavior indicators (e.g., frequency of proactive interactions, duration of eye contact) and qualitative interviews recording participants’ subjective experiences. Paired-sample t-tests (significance level p \u3c 0.05) were performed using SPSS 26.0, and thematic coding was conducted via NVivo 12. Post-intervention, the experimental group showed a 42% increase in proactive interaction frequency (t=3.21, p=0.006) and a 35% rise in eye contact duration (t=2.89, p=0.013). Qualitative analysis revealed that ritualized movements reduced anxiety levels (83% mention rate), while repetitive rhythms provided emotional safe anchors (76% mention rate). The control group exhibited no significant changes. A typical case indicated that 9 patients in the experimental group achieved peer acceptance, with a 67% reduction in social avoidance behaviors. This study validates the effectiveness of ethnic traditional sports in improving social skills among autism patients through the body narrative—cultural identity—social reconstruction pathway. Their non-verbal interaction patterns bypass language barriers and foster emotional bonds, offering a novel paradigm for localized interventions. It is recommended to integrate traditional sports into mental health service systems and further explore their integration with modern technologies
A187: The Comprehensive Impact of Competitive Liondance on Bio-Psycho-Social Health: Cohort Tracking Study of Elite Athletes
No full textCompetitive lion dance, a traditional sport that integrates artistic performance, cultural heritage, and high-intensity physical training, has not yet been systematically studied for its multidimensional health benefits. Method: This study investigates the comprehensive impact of competitive lion dance on the bio-psycho-social health of elite athletes through a 12-month longitudinal cohort tracking. Thirty-two national-level competitive lion dance athletes (18 males and 14 females, aged 22.5 ± 3.1 years) were recruited and assessed at three time points: baseline, 6 months, and 12 months. Biological health indicators included cardiorespiratory fitness (maximal oxygen uptake, VO₂max), muscle strength (isokinetic strength test), and body composition analysis. Mental health was evaluated using the Self-Rating Anxiety Scale (SAS), Self-Rating Depression Scale (SDS), and Psychological Resilience Inventory (PTI). Social health was quantified through the Social Support Rating Scale (SSRS) and Team Cohesion Questionnaire (TCQ). (1) In the biological health dimension, VO₂max increased by 12.3% (p \u3c 0.01), lower limb explosive power improved by 18.7% (p \u3c 0.001), and body fat percentage decreased by 4.2% (p \u3c 0.05). (2) In the mental health dimension, anxiety and depression scores decreased by 26.5% and 21.8%, respectively (p \u3c 0.01), while psychological resilience improved by 34.2% (p \u3c 0.001). (3) In the social health dimension, the total social support score increased by 29.1%, and team cohesion improved by 40.6% (p \u3c 0.001). Correlation analysis revealed that physiological improvements were significantly positively correlated with psychological resilience (r = 0.62) and team cohesion (r = 0.57). This study confirmed that the competitive lion dance achieved three-dimensional health gain through high-intensity interval training (body fat 4.3%, p \u3c0.001), cultural ritual integration (CD-RISC 29%), and team coupling effect (network density 78.1%). Compared with the single physiological improvement of traditional sports (such as cardiopulmonary function study in martial arts), the social capital reconstruction (central Gini coefficient 0.18) and anxiety relief (β = -0.43) highlight the characteristics of intangible cultural heritage sports. Limitations involve sample size and control of confounding variables, including further dose-effect studies combined with wearable devices. At the practical level, the intangible cultural heritage + health model: the ritualized collaboration mechanism can be developed as a group psychological intervention tool for teenagers, metabolic gain (resting metabolic rate 8.7%) to adapt to the chronic disease exercise prescription system, and provide culture-driven solutions for the integration of health
A236: Effects of Four-Week Blood Flow Restriction Combined with Functional Training on Physical Fitness in the Elderly
No full textFalls resulting from age-related declines in physical function significantly affect the quality of life in older adults and increase healthcare costs. While functional training (FT) helps mitigate these declines, its impact on metabolic load is limited. Blood flow restriction (BFR) training, which enhances metabolic stress through low-intensity exercise, has emerged as a promising alternative. This study aimed to investigate whether combining BFR with FT (BFR-FT) leads to greater improvements in physical fitness in older men compared to FT alone. Thirty healthy older men (71.07±5.51 years) were randomly assigned to FT, BFR-FT, or control (CON) groups. The study included pre-test, intervention, and post-test phases. Pre-test data were collected one week before the intervention. Physical fitness was assessed using the Timed Up-and-Go, 2-Minute Step, Functional Reach, Chair Sit-and-Reach, 30-Second Arm Curl, and 30-Second Chair Stand tests. Fall self-efficacy was measured using the Modified Falls Efficacy Scale (MFES). The FT program included 11 functional exercise stations. Participants performed 10 repetitions per station and completed three circuits per session. The intervention lasted four weeks, with three sessions per week. For the BFR-FT group, the same FT exercises were performed with blood flow restriction cuffs worn on the proximal limbs. Arterial occlusion pressure was measured during the pre-test using an ultrasound Doppler probe, and cuffs were maintained at 50% arterial occlusion pressure throughout training. Post-tests were conducted using the same procedures as pre-tests for consistency. Data were analyzed using two-way ANOVA, with post-hoc LSD tests for group comparisons. Significant main effects of group and time were observed in the Timed Up-and-Go (p \u3c 0.001), 2-Minute Step Test (p \u3c 0.001), Functional Reach Test (p=0.013), and 30-Second Chair Stand (p \u3c 0.001), with the BFR-FT group outperforming both the FT and CON groups. Significant differences were also found in the 30-Second Arm Curl (p \u3c 0.001) and MFES (p \u3c 0.001), favoring BFR-FT over FT alone. No significant interactions were found for the Chair Sit-and-Reach Test. This study shows that combining BFR with FT significantly improves mobility, balance, and strength in older adults, compared to FT alone. BFR enhances the metabolic load of low-intensity exercise, enabling significant muscle activation without excessive strain, making it ideal for older adults. FT improves functional mobility and coordination, and when combined with BFR, maximizes training benefits and reduces fall risk. The results provide preliminary support for the BFR-FT intervention, offering valuable insights into improving physical function and overall well-being in older adults
