A180: Effects of Weight Loss Program on Physiological and Mental Health in College Students
No full textWith the accelerated pace of modern society, the prevalence of obesity and overweight among college students has become increasingly severe, posing significant risks to both physical and mental health. Obesity not only elevates the likelihood of chronic diseases such as cardiovascular disorders and diabetes but also adversely impacts psychological well-being, including diminished self-confidence and impaired social skills. Therefore, this study aims to investigate the effects of a weight loss and body shaping program on the physical and mental health of college students, providing a scientific foundation and practical guidance for implementing such programs in universities. Eighty-nine students (49 females, 40 males) were recruited from a Chinese university and completed a 12-week weight loss and body shaping intervention program (March to June 2024). The program included aerobic exercise, strength training, dietary guidance, and body index monitoring, consisting of three 60-minute sessions per week. Before and after the intervention, professional instructors measured body weight, BMI, body fat rate, skeletal muscle mass（SMM）, and basal metabolic rate(BMR). Mental health status was assessed using the SCL-90 scale. Data analysis was performed using paired sample t-tests, with the significance level set at P \u3c 0.05. Following the intervention, significant reductions in BMI and body fat rate were observed among the students. In the male group, BMI decreased from 26.87±10.13 to 25.75±8.89 (p \u3c 0.01), while in the female group, BMI decreased from 25.36±23.69 to 24.26±16.57 (p=0.0078). Body fat in the male group decreased from 25.33±42.67 to 22.62±46.98 (p=0.02), and in the female group, it decreased from 36.13±81.39 to 31.54±76.22 (p=0.07). Female SMM significantly increased (40.79±38.41 vs. 42.75±37.38, p=0.009), and BMR significantly improved (1308±20070 vs. 1351.75±19421.67, p \u3c 0.01). However, no significant changes were observed in SMM or BMR in the male group. SCL-90 scale results indicated significant reductions in interpersonal sensitivity, depression, and anxiety scores. The intervention program significantly improved both Physiological and mental health among college students, demonstrating reductions in body fat, increases in SMM, and enhancements in BMR, with particularly pronounced effects observed in female participants. It is worthy of promotion and implementation in universities, integrating dietary guidance and psychological interventions to provide comprehensive health management services for students. Future research should further explore the effects of different program modalities and training intensities on college students\u27 health to optimize program design and enhance intervention efficacy
A022: University Students\u27 Physical Activity Motivation and Gender-Related Factors
No full textPhysical activity is essential for young adults, offering physical, psychological, aesthetic, and social benefits, such as reduced chronic disease risks, improved mental health, and overall wellbeing. Despite WHO recommendations (60 minutes daily for adolescents, 150 minutes weekly for adults), many college students fall short due to low intrinsic motivation, body image concerns, social anxiety, and lack of enjoyment. This study examines college students\u27 motivations for physical activity and their relationships with gender, activity levels, and satisfaction. It also explores how motivation mediates the influence of gender on activity levels and satisfaction. Method: Exploratory analyses and bivariate analyses (Pearson’s correlations and t-test) were calculated using IBM’s SPSS software (v.26). Effect size in mean differences was estimated using Cohen’s d. This study surveyed 1,099 university students (mean age 20.4, SD 1.5) in Zhengzhou, with 56.7% females and 43.3% males. Using a cross-sectional design, data were collected through the BREQ-2 questionnaire, assessing four motivation dimensions—intrinsic, identified, introjected, and external—alongside weekly physical activity duration and satisfaction. The BREQ-2 scale measurement model showed a good fit (SRMR = 0.034, RMSEA = 0.078, CFI = 0.969, NFI = 0.958). Intrinsic motivation had the strongest variance with other motivations, followed by identified and introjected regulation, while external regulation showed weaker correlations and a negative link with intrinsic motivation. Higher levels of intrinsic, identified, and introjected regulation correlated with more physical activity and greater satisfaction, while external regulation was unrelated to activity time and negatively linked to satisfaction. Males demonstrated higher intrinsic and external regulation levels and engaged in 2.45 more weekly activity hours than females, though satisfaction levels were similar. Mediation analysis revealed that intrinsic regulation significantly mediates gender’s impact on both physical activity volume and satisfaction. This study identifies significant gender differences in physical activity and motivation, with males showing higher intrinsic and external regulation motivation and greater activity levels. Intrinsic regulation mediates the relationship between gender, activity volume, and satisfaction. Key limitations include the cross-sectional design, which precludes causal inferences, and the use of the brief BREQ-2 scale, suggesting future research should adopt longitudinal designs and more comprehensive tools for assessing motivation. Practically, universities can use these findings to design targeted interventions to boost intrinsic motivation among female students and enhance activity participation. Providing more resources and opportunities for physical activity can further support student health and well-being
A081: Characterizing Resting-State Functional in College Students Practicing Combat Sports: A Cross-Sectional Neuroimaging Study
No full textLong-term physical exercise is known to induce changes in brain plasticity. While extensive research has examined the effects of aerobic exercise, basketball, and badminton on brain plasticity in college students, the impact of combat sports on brain function remains underexplored. Combat sports, due to their high intensity and mental demands, may have unique effects on neuroplasticity. This study aims to investigate the influence of combat sports participation on brain function in university students, addressing a gap in the current literature. Method: This study comprised three groups: an experimental group of 14 students (8M/6F, 20.9 ± 2.3 years) practicing combat sports (Taekwondo, Judo, Brazilian Jiu-Jitsu, Chinese kickboxing, Muay Thai) for 2.4 ± 0.9 years; an aerobic group of 15 students (9M/6F, 22.0 ± 2.3 years) with 2.2 ± 1.0 years of experience; and a sedentary control group of 17 students (7M/10F, 20.3 ± 1.2 years). Brain imaging data were acquired using a Philips scanner, with T1WI capturing structural signals and EPI sequences acquiring resting-state BOLD signals. The data were preprocessed using RestPlus12 software, followed by the calculation of fractional Amplitude of low-frequency fluctuations (fALFF). Based on previous research, regions of interest (ROIs) were defined in the left premotor cortex (PMC), supplementary motor area (SMA), dorsal premotor cortex (dPMC), mid temporal gyrus (MTG), and bilateral hippocampus (Hipp). The fALFF signals from these ROIs were extracted for statistical analysis. A one-way ANOVA was first conducted to compare the three groups, followed by pairwise comparisons using t-tests. The ANOVA revealed significant differences among three groups in PMC (F = 13.509, p 0.00), dPMC (F = 5.809, p = 0.006), MTG (F = 5.013, p = 0.011), HippL (F = 10.338, p 0.00). The Combat group exhibited significantly higher fALFF than the controls in the left PMC (p \u3c 0.001), SMA (p = 0.05), dPMC (p = 0.008), and MTG (p = 0.004). Additionally, compared to the aerobic group, the Combat group demonstrated higher fALFF in the left dPMC (p \u3c 0.001), while lower fALFF in the HippL (p = 0.017). The current findings suggest that long-term participation in combat sports leads to functional reorganization and optimization in brain regions related to motor planning, coordination, and execution in college students. Additionally, its effects on brain areas associated with motor control appear to be more favorable than those observed with aerobic exercise alone
A113: Smart Assessment in University PE Teaching
No full textWith the development of educational information and intelligence, the evaluation and improvement of teaching effectiveness in university physical education (PE) have become a research focus. Traditional assessment methods struggle to comprehensively reflect teaching outcomes, while smart technologies offer new approaches for precise evaluation. This study aims to construct a smart technology-based assessment model for university PE teaching effectiveness and explore its practical application to promote innovative development in PE teaching. This study adopts a quasi-experimental design, involving 300 PE teachers and 1500 students from five universities in China. The experimental group used a smart assessment system (including wearable devices and AI classroom analysis tools), while the control group used traditional assessment methods. Data were collected in real-time through smart devices, including student movement data, classroom engagement, and teaching behaviors. Surveys and focus group interviews were conducted to gather feedback from teachers and students. Data analysis employed a mixed-methods approach, with quantitative data analyzed using SPSS for multifactorial ANOVA and qualitative data analyzed using NVivo for thematic analysis. The experimental group significantly outperformed the control group in all dimensions of teaching effectiveness (skill acquisition, classroom engagement, and teaching satisfaction \u3c 0.01). The smart assessment system accurately captured student movement data and classroom performance, providing real-time feedback to teachers. Qualitative analysis revealed high acceptance of smart assessment among teachers and students, who believed it enhanced teaching transparency and personalized guidance. This study is the first to systematically apply smart technologies to assess university PE teaching effectiveness, demonstrating its efficacy. Compared to previous research, this study emphasizes the deep integration of technology and teaching, offering a new paradigm for PE assessment. Future research should focus on optimizing the applicability and cost-effectiveness of smart systems. The practical significance lies in providing an actionable smart assessment framework for university PE, contributing to the overall improvement of teaching quality
A237: Research on the Construction of the Standard System in the Field of Sports-Medicine Integration
No full textThe standard system serves as a crucial foundation for promoting the standardized and high-quality development of sports-medicine integration. Currently, the development of sports-medicine integration in China remains in its exploratory stage, facing challenges such as the lack of cross-domain standards and an incomplete standard system architecture, which hinder its standardized and high-quality advancement. This study aims to analyze the connotation of the standard system in the field of sports-medicine integration, identify challenges in its construction, and propose targeted recommendations. A combination of literature review, logical analysis, field surveys, and statistical methods was employed to conduct theoretical and practical analyses on the connotation, significance, challenges, and recommendations for the standard system in sports-medicine integration. Statistical analysis involved retrieving published standards in this field from the China Standards Information Public Service Platform, including data on the quantity, timing, levels, and administrative units of the standards. The standard system for sports-medicine integration is a systematically designed collection of standards or specifications that integrates technology development, service processes, facilities, personnel qualifications, data management, and other requirements in the interdisciplinary field of sports and healthcare, guided by current needs and future development goals. It serves as a blueprint for standardization efforts and a critical foundation for formulating and revising standards in this field. Three key challenges were identified: (1) The lack of interdepartmental coordination between sports and healthcare administrations leads to fragmented standard development. (2) A shortage of interdisciplinary professionals proficient in sports science, clinical medicine, and standardization creates barriers to standard research. (3) There is a critical deficiency in core technical standards, leaving essential domains of sports-medicine integration—such as service protocols, personnel certification, health risk evaluation, and wearable device data governance—without authoritative or implementable regulatory frameworks. Improving the standard system for sports-medicine integration is essential for its standardized and high-quality development. Recommendations include: (1) Establishing a technical organization for sports-medicine integration standardization and a cross-departmental collaborative governance mechanism to coordinate standard system construction. (2) Innovating interdisciplinary education models, strengthening talent cultivation, and building expert databases for standard development. (3) Implementing a challenge-oriented mechanism to prioritize the formulation of key standards, ensuring comprehensive service standards across the entire sports-medicine integration chain
A202: Biomechanical Analysis of Drop Landing Technique in Male Basketball Players Under Muscle Fatigue
No full textEpidemiological studies indicate that fatigue is a significant contributor to knee injuries among athletes. Drop-landing (DL) is one of the most prevalent maneuvers in basketball, utilized for jump shots, sudden stops, and passing. The primary objective of this study was to investigate the effects of fatigue on basketball players\u27 joint angles, moments, and initial contact times during drop-landing tasks. Method: Fifteen male Division II basketball players (aged 20.43 ± 1.62 years, height: 180.14 ± 3.76 cm, mass: 74.43 ± 7.39 kg) from the Faculty of Sports Science at Ningbo University were recruited. Ten Vicon three-dimensional motion capture cameras were utilized to collect kinematic data from the participants performing deadlifts (DL) before and after fatigue at a frequency of 200 Hz, while a Kistler force plate was employed to gather kinetic data during the experiment at 1000 Hz. The collected kinematic and kinetic data were imported into Visual 3D software, where they were Butterworth filtered at 20 Hz and 50 Hz, outliers were removed, and the data were subsequently exported to SPSS for paired t-tests. The significance level was established at 0.05. Significant differences were observed in joint angle. Post-fatigue exhibited higher ankle external rotation angle (P=0.006) and knee abduction angle (P=0.031). The ankle joint ROM in the transverse plane and coronal plane was significantly larger than pre-fatigue (p=0.036, p=0.020). The knee joint ROM was significantly larger than pre-fatigue (p＜0.001). At the initial contact of the drop landing, the knee joint showed a higher flexion angle (p=0.003). The hip joint angle was not significantly different between pre- and post-fatigue. However, the hip joint flexion moment was significantly higher than pre-fatigue (p=0.019). When performing depth jumps (DL) after experiencing fatigue, participants exhibited greater knee flexion angles at initial contact, indicating an extended duration required to stabilize their bodies post-fatigue during DL. These findings suggest that fatigue induces significant biomechanical alterations, such as diminished joint stability and compensatory movement patterns, which may elevate the risk of injury during dynamic tasks. The results underscore the necessity for fatigue-specific training protocols aimed at enhancing neuromuscular control and mitigating injury risk in athletes
A003: The Relationship Between Personal Values and Leisure-Time Exercise: A Three-Wave Longitudinal Study
No full textAlthough the benefits of exercise have been firmly established, numerous young people continue to engage in low levels of exercise. In studies of exercise behavior facilitators, exercise motivation has been mostly applied to eliciting an individual\u27s exercise behavior. However, motivation is influenced by various factors and is unlikely to remain stable over time. Consequently, to ensure the sustained participation in exercise of young people, it’s significant to find more stable facilitators of exercise behaviors. This study, grounded in the self-determined theory and Schwartz’s personal values model, begins by focusing on a more stable behavioral determinant, personality—personal values—to provide a deeper understanding of the mechanisms underlying exercise behavior. Method: 522 participants (193 Females and 329 Males; Mage = 19.32, SD = 1.02) in China were included. A three-wave longitudinal study design, which permitted relationship research, was adopted (T1 = personal values and exercise motivations, T2 = exercise intention, T3 = leisure-time exercise behavior). The “Revised Portrait Value Questionnaire” was used to measure personal values; the “Behavioral Regulation in Exercise Questionnaire-2” was used to measure exercise; the “Exercise Intention Scale” was employed to measure exercise intention; the “Godin Leisure-Time Exercise Questionnaire” was used to measure exercise behavior. All data were collected during regularly scheduled PE classes. Data analysis included computation of scale reliability, descriptive statistics, bivariate correlations, and a path analysis. Results revealed all the scales demonstrated good scale reliability (α = 0.78–0.93). The Structural equation modeling indicates a good model fit (RMSEA=0.051, CFI=0.910, TLI=0.90, SRMR=0.078). The results indicate that security-personal value can predict leisure-time exercise (β=0.059, p \u3c 0.001) and identified regulation and exercise intention mediate this relationship. Achievement value can predict leisure-time exercise (β=0.089, p \u3c 0.01). Introjected regulation and exercise intention mediate this relationship. Hedonism value can predict leisure-time exercise (β=0.143, p \u3c 0.001). Intrinsic motivation and exercise intention mediate this relationship. Conformity-interpersonal value is not related to leisure-time exercise. Consistent with relevant literature, this study suggests that some personal values can predict exercise behaviors, and exercise motivation and intention can mediate this relationship. Since most research focuses on short-term predictors such as motivation of exercise behavior, this examined more stable psychological variables capable of predicting exercise behavior, thus enriching the theoretical discourse on personal values and exercise behaviors, while providing practical insights for intervention strategies
A129: Comparison of the Full Kinematic Sequences of Driver and 7 Iron in College Male Golfers
No full textA reasonable full kinematic sequence enables the club to obtain maximum speed in impact, avoiding technical errors and reducing sports injuries. By comparing the kinematic sequences during the full swings of the driver and 7-iron of college male golfers, the kinematic characteristics of different clubs were analyzed in relation to the technical differences. Method: An infrared high-speed motion capture system (sampling frequency 250Hz, Qualisys, Sweden) was applied to capture the full-swing technical movements of 6 male golfers\u27 driver and 7-iron five times each, with an interval of 30s. The Qualisys Sports Marker Set-golf model in the Qualisys system was used. The kinematic analysis of the raw data captured by the Qualisys system was analyzed using Visual 3D software. (1) In the Backswing, the time taken by each segment (pelvis, torso, lead arm, and club) from the point of take-off to peak angular velocity was positively correlated with club speed (CSI) for both the driver and 7-iron (P \u3c 0.05). (2) In the Transition, the time taken for torso rotation to the top of backswing in the driver was significantly greater than the time taken for the 7iron at 18.47ms (P \u3c 0.05), the time taken for pelvis rotation to impact in the driver was significantly greater than the time taken for the 7iron at 19.60ms (P \u3c 0.01), and the time taken for lead arm rotation to the moment of impact in the driver was significantly greater than the time taken for the 7iron at 10.80ms (P \u3c 0.01). (3) In the Downswing, the peak pelvic angular velocity of the driver was significantly greater than the angular velocity of the 7iron by 37.50°/s (P=0.01), the peak torso angular velocity of the driver was significantly greater than the angular velocity of the 7iron by 53.70°/s (P \u3c 0.01), and the peak lead arm angular velocity of the driver was significantly greater than the angular velocity of the 7iron by 109.40°/s (P \u3c 0.01). There was no significant difference in the kinematic sequence between driver and 7iron in the Backswing, and a slow start at the takeaway is favorable for CSI. The longer shaft length of the driver compared to the 7-iron required more torso rotation in the transition. Peak angular velocity of the pelvis, torso, and lead arm is the primary factor in generating faster CSI
A137: Effects of Different Static Calibration Postures on Knee Mechanics During Running: Statistical Parametric Mapping Analysis
No full textWith the increase in life expectancy and the health benefits of exercise, running has become a popular physical activity. Nonetheless, the incidence of running-related injuries remains high. Knee mechanics during running, particularly excessive movements and angles in the frontal and transverse planes, have been identified as potential biomechanical risk factors for the development of injuries. Variations in the frontal and transverse plane measurements across studies may result from differences in static standing postures, such as toe-in or toe-out positions, which might influence knee mechanics during running. This study aimed to identify the effects of different static standing postures on knee mechanics during running. Twenty healthy participants (10 males and 10 females; age: 24.7±1.3 years; height: 1.73±0.08 m; weight: 66.5±10.7 kg) completed three different static calibration trials: (1) 30° toe-in, (2) 0° neutral position, and (3) 30° toe-out, prior to running at their self-selected speeds. A twelve-camera three-dimensional VICON motion analysis system, integrated with two AMTI force platforms, was utilized to capture knee mechanics data during running. Repeated-measures ANOVA with statistical parametric mapping (SPM) was applied to assess differences across static calibration posture trials. Significant differences were observed in knee flexion angle (29.7%-33.8%, F=5.55, p=0.048), adduction/abduction angle (0-100%, F=129.01, p \u3c 0.001), and internal/external rotation angle (0-100%, F=58.58, P \u3c 0.001). Post hoc analyses revealed that, compared to 0°, knee flexion angle decreased with greater toe-in angles during the early stance phase (p=0.006). Knee flexion angle increased progressively (p \u3c 0.001), while internal rotation angle decreased progressively during most of the stance phase (p \u3c 0.001), with greater toe-out angles. Significant differences were found in knee extension moments (0-1.8%, F=16.34, p \u3c 0.045;9.9%-10.1%, F=6.16, p \u3c 0.05; 11.7%-13.7%, F=7.26, p \u3c 0.045; 14.2%-21.9%, F=9.32, p \u3c 0.008) and knee adduction moments (9.3%-55.3%, F=63.16, p \u3c 0.001; 64.8%-86.4%, F=39.06, p \u3c 0.001). Post hoc analyses revealed that knee internal moment decreased with greater toe-out angles (p \u3c 0.001); however, knee extension moment increased with greater toe-out angles only in the early stance phase (p \u3c 0.05). No significant differences in knee internal rotation moment were observed across conditions (p \u3e 0.05). This study represents the first attempt to utilize SPM to analyze the effects of different static postures on knee mechanics during running. Alterations in static standing postures significantly influenced knee mechanics measurements. Consequently, this study underscores the critical need to standardize foot positioning in static trials to minimize potential misinterpretations of intervention efficacy and intergroup differences in clinical research
A303: Is Physical Literacy the Panacea for Gaming Disorder? A Novel Perspective on Exercise Intervention
No full textAdolescent gaming disorder has become a critical public health issue, driven by its association with reduced physical activity and increased risks of chronic diseases. WHO identifies physical inactivity as the fourth leading global risk factor for mortality. To address this challenge, research highlights the effectiveness of exercise interventions, which work by modulating reward systems, enhancing neuroendocrine adaptability, improving self-efficacy, social skills, and time management. These interventions replace virtual stimuli from gaming with real-world physical engagement, fostering healthier lifestyles. Physical literacy, which emphasizes cultural and holistic engagement with physical activity, extends beyond traditional mechanical exercises and underscores the importance of addressing gaming disorder through movement and health promotion. Method: This study conducted a systematic review using the keywords gaming disorder, exercise intervention, and adolescents, and integrated physical literacy theory to develop a three-tiered intervention framework targeting gaming disorder, which provide theoretical support for exercise interventions in individuals with gaming disorder Firstly, enhancing motor skills enables individuals to build physical confidence, thereby disrupting the addictive psychological cycle of “self-worth” being dominated by the virtual world. Secondly, by harnessing the natural release of dopamine and endorphins during physical activity to substitute for the instant gratification derived from gaming, this mechanism effectively alleviates addiction-related negative emotional states such as anxiety and depression. Thirdly, diverse physical activity experiences involving team collaboration and goal-setting reshape individuals\u27 sense of belonging in real-world social interactions, thus reducing excessive dependence on virtual socialization. Research indicates that physical literacy theory provides an innovative approach to intervening in gaming disorder. Specifically, by developing individuals\u27 physical literacy to block the physiological and psychological triggers of addiction while concurrently establishing foundational capacities for healthy lifestyles, this approach enables adolescents to attain sustainable physical-mental fulfillment and developmental motivation in the real world. Physical literacy theory not only has significant value in promoting individual health but also plays a vital role in addressing gaming disorder. Future research should further integrate multidisciplinary resources spanning education, healthcare, and public policy to translate physical literacy frameworks into broadly applicable health action programs
