A088: Best Core Stability Training Program for Lower Limb Dysfunction in Stroke Patients: A Network Meta-Analysis
No full textStroke is the third leading cause of disability and the second leading cause of death among adults. Lower limb dysfunction caused by stroke significantly impairs patients\u27 quality of life. Numerous studies have demonstrated that core stability training (CST) can effectively improve lower limb function in stroke patients, and combining CST with other rehabilitation approaches may yield better therapeutic outcomes. This study aims to identify the most effective CST-based combined intervention for treating lower limb dysfunction in stroke patients. Method: Randomized controlled trials (RCTs) published up to July 22, 2024, were searched from PubMed, Embase, Cochrane Library, Web of Science, CNKI, and SinoMed. The quality of the included studies was assessed using the Cochrane Risk of Bias tool (ROB 2.0). Network meta-analysis was performed via R Studio and STATA 15.0. The optimal intervention strategy was explored using two-dimensional clustering analysis. For balance ability in stroke patients, the rehabilitation effect of neuromuscular electrical stimulation combined with core stability training (NMES+CST) was the most effective, with a surface under the cumulative ranking curve (SUCRA) of 91.09%. For functional mobility of the lower extremity in stroke patients, proprioceptive training combined with core stability training (PT+CST) showed the best rehabilitation effect (SUCRA=93.24%). For motor ability of the lower extremity, acupuncture therapy combined with core stability training (AT+CST) was the most effective (SUCRA=90.83%). For walking ability, motor imagery training combined with core stability training (MIT+CST) demonstrated the optimal rehabilitation effect (SUCRA=92.40%). Cluster analysis results indicated that the optimal treatment regimens for stroke-induced lower extremity dysfunction were PT+CST (SUCRA=56.75%/93.24%/63.59%/53.80%) and AT+CST (SUCRA=79.15%/ 90.83%/65.46%). NMES+CST, PT+CST, AT+CST, and MIT+CST are four effective core stability training combination therapies. Comprehensive evaluation results indicate that AT+CST or PT+CST is the optimal core stability training combination therapy for lower extremity dysfunction in stroke patients. Since AT is a traditional Chinese medicine treatment method, physicians should consider patients\u27 acceptance of this intervention and cultural differences. Future research should explore long-term effects, individualized treatment protocols, and underlying mechanisms to optimize rehabilitation outcomes
A005: Effect of Blended Learning on Junior High School Students’ Fancy Rope-Jumping Learning: An Empirical Study
No full textBlended learning is a teaching style characterized by combining the advantages of online teaching with traditional teaching to improve the efficiency and quality of learning. At present, blended learning has achieved good results in most subjects, but little research is exploring its application in middle school physical education. This study investigated the application of blended learning in junior high school students\u27 fancy rope-jumping learning. Method: Ninety students were assigned from a junior high school in Nanshan District, Shenzhen, including the experimental group of 42 students (boys=22, girls=20) who used blended learning, and the control group of 48 students (boys=23, girls=25) who received traditional learning. All participants took part in a 40-minute lesson twice weekly for 12 weeks. Both groups of students were tested on physical fitness and fancy rope-jumping skills before and after the intervention, and the outcomes were recorded. A t-test was used to analyze the results of the two groups of students before and after the intervention. After 12 weeks of intervention, there were significant improvements in physical fitness and fancy rope-jumping skills in both groups(p \u3c 0.001). However, there w no difference in the post-test results of physical fitness between the two groups (p \u3e 0.05)n the fancy rope-jumping skills, there were differences between the two groups in the 1-minute Single Shake Jump, 30-second Double Shake Jump, and 1-minute Interval Cross Jump(p \u3c 0.05), there was no difference in 1-minute Continuous Cross Jump(p \u3e 0.05). Compared with the pre-test, the experimental group students in Lung Capacity, Standing Long Jump, and Sitting Forward Bend had significantly different results than before (\u3c 0.001); there was no difference between the pre-test and post-test results of 800/1000 Meters Running (\u3e 0.05). The control group showed significant differences in the results of the four indexes of Lung Capacity, Standing Long Jump, Sitting Forward Bend, and Sit-ups/Pull-ups (\u3c 0.001), there was no difference in the 50 Meters Running=0.766), and 800/1000 Meters Running test (0.114). However, two groups showed significant differences in fancy rope-jumping skills (\u3c 0.001). This research shows that blended learning can effectively improve junior high school students’ mastery of fancy rope-jumping skills compared with traditional learning, with the benefits of improved physical fitness for students
A293: Effects of Aquatic Exercise on Cardiovascular Health in the Elderly: A Systematic Review and Meta-Analysis
No full textAccording to the Report on Cardiovascular Health and Diseases in China 2023， the number of patients with cardiovascular disease (CVD) in China has reached 330 million. CVD is the disease with the highest mortality rate, and the elderly population has the greatest risk. In the context of strategies of the Healthy China initiative and A Leading Sporting Nation, it is urgent to use exercise intervention to prevent and treat major chronic diseases such as CVD under the concept of exercise is good medicine, promote the deep integration of national fitness and national health. Aquatic exercise is a novel exercise intervention therapy, which refers to the use of physical properties such as buoyancy, pressure, resistance, and temperature of water to promote physical health. Purpose: To systematically evaluate the effect of regular aquatic exercise on the cardiovascular health of the elderly by using eta-analysis. Method: Two researchers searched PubMed, Web of Science, ScienceDirect, EBSCO, CNKI, and CBM from January 2000 to December 2023 for randomized controlled trials (RCTs) of the effects of regular aquatic exercise on cardiovascular health in the elderly in strict accordance with the inclusion and exclusion criteria independently. The Cochrane risk of bias assessment tool was used to evaluate the quality of the literature, and Revman 5.4.1 software was used for analysis. A total of 18 RCTs were included, with a total of 749 elderly subjects. The results showed that regular aquatic exercise could significantly improve the systolic blood pressure (SBP) [WMD=-4.17, 95%CI (-8.09, -0.26), P=0.04], diastolic blood pressure (DBP) [WMD=-3.39, 95%CI (-6.35, -0.43), P=0.02], resting heart rate (HRrest) [WMD= -4.33, 95%CI (-6.97, -1.70), P=0.001], maximum oxygen uptake (VO2max) [WMD=1.93, 95%CI (1.58, 2.29), P \u3c 0.00001], peak oxygen uptake (VO2peak) [WMD=3.40, 95%CI (0.39, 6.41), P=0.03]. However, its effect on random blood glucose (Glu), total cholesterol (TC), triglycerides (TG), high-density lipoprotein cholesterol (HDL-C), and low-density lipoprotein cholesterol (LDL-C) in the elderly has not been determined, and the combined effect size （SMD） was not statistically significant (P\u3e0.05). Regular aquatic exercise can significantly reduce SBP, DBP, and HRrest of the elderly, improve VO2max and VO2peak. More high-quality studies are needed to further demonstrate the impact of regular aquatic exercise on important indicators affecting cardiovascular health, such as blood lipids and blood glucose in the elderly
A045: Research on Enhancing Physical Education in Universities Under the Three Comprehensive Educations
No full textThree-Wide Education is an important concept for colleges in the new era to implement the fundamental task of fostering virtue through education. As an essential component of higher education, college physical education plays a unique role in promoting students\u27 physical and mental health, cultivating well-rounded personalities, and shaping correct values. However, current college physical education still faces issues such as prioritizing skills over moral education, monotonous teaching content and methods, and an imperfect evaluation system, which hinder the full realization of its educational function. Therefore, exploring the effectiveness enhancement path of college physical education under the Three-Wide Education framework is of great significance for improving the quality of college physical education and cultivating well-rounded socialist builders and successors with moral, intellectual, physical, aesthetic, and labor development. This study focuses on H University, using questionnaires and interviews. Surveys target students to assess their satisfaction, engagement, and awareness of physical education\u27s educational role. Interviews with teachers and administrators explore their understanding of Three-Wide Education, current teaching practices, and challenges. Some teachers have a superficial understanding of the Three-Wide Education concept, equating physical education with skill instruction while neglecting the cultivation of students\u27 moral character, ideological development, and willpower. The teaching content primarily focuses on traditional sports, lacking modernitywhich makes it difficult to stimulate students\u27 interest. The teaching methods mainly involve teacher demonstrations and student practice, lacking interactivity and innovation. The current evaluation system overly emphasizes the assessment of sports skills and physical fitness, neglecting the evaluation of students\u27 learning attitudes and teamwork spirit. Under the background of Three-Wide Education, college physical education needs to take the realization of fostering virtue through education as its fundamental task. Improving the quality of physical education can promote students\u27 physical and mental development, enhance their comprehensive qualities, and cultivate well-rounded personalities. Therefore, when conducting teaching activities, college physical education teachers should focus on students, aim to promote their comprehensive development, and adopt effective measures to enhance the effectiveness of college physical education by addressing the existing problems and shortcomings. The limitation of this study lies in its focus on H University as a single case, and the generalizability of the conclusions requires further verification. Future research could expand the sample size and conduct more in-depth analysis and exploration
A059: Effects of Jump-Rope Exercise Snacks on the Feasibility and Perceived Effects of Inactive College Students
No full textThe compliance rate of college students’ physical health in China is on the decline. About 30% of college students in China fail in physical health, and nearly half exercise less than 3 times a week. To solve this problem, a strategy called Exercise Snacks (ES) is proposed, which is to carry out high-intensity intermittent exercise in a short time and using scattered time to increase daily activity. The purpose of this study is to explore the feasibility and perception effect of rope skipping snacks in campus life and provide a new way to solve the problem of insufficient exercise for young people. Method: Thirty-three female college students who lacked exercise were randomly divided into the ES group, moderate intensity continuous training (MICT)group, and control group (CON). The ES group and the MICT group trained 3 times a week for 8 weeks, and the CON group maintained their original living habits. The ES group performed rope skipping training for 3×60s three times a day; the MICT group performed a 30-minute treadmill jog with a maximum heart rate of 60-70%. Physical indicators and physical activity data were collected. Physical Activity Enjoyment Scale (PACES)was used to evaluate pleasure, quality of life (EQ-5D-5L), and perceived stress scale (PSQ)were used to evaluate perceived effect. The ES group and the MICT group were positive in feasibility and perceived effect. Compared with the CON group, the physical activity level of the two groups significantly improved, and there was no significant difference. In terms of pleasure, ES and MICT were higher (PACES were 93±12.6,90±8.5, respectively), and there was no significant difference. Compared with baseline, EQ-5D-5L was increased by 9%(MD=5.5) in ES group,6%(MD=4.5)in MICT group, and 8%(MD=-5.3)in CON group. There was no significant difference between ES and MICT. The PAQ value of the ES group decreased by 10%, the MICT group increased by 8%, and there was no significant change in the CON group. There was a significant difference between ES and MICT (P \u3c 0.05). 8-week rope skipping is feasible among college students. Both ES and MICT positively affected physical activity, pleasure, and quality of life. Compared with MICT, ES has greater advantages in reducing perceived stress and higher acceptance of participants. However, the sample size of the study is limited, and future research needs to expand the sample and explore long-term effects
A026: Associations Between Energy Metabolism and Sarcopenia Prevalence and Mortality in Older Adults
No full textSarcopenia, characterized by the progressive loss of skeletal muscle mass, strength, and function, is a geriatric syndrome with a significantly increased incidence with age. It has become a major public health concern affecting the health of middle-aged and older adults. This study aims to investigate the associations between leisure-time physical activity (LPA), occupational physical activity (OPA), and transportation physical activity (TPA) with sarcopenia and all-cause mortality among older adults in the United States. Data were derived from the National Health and Nutrition Examination Survey (NHANES) from 1999 to 2018, with all-cause mortality tracked through the National Death Index (NDI) until April 16, 2022. Multivariable logistic regression, multivariable Cox proportional hazards regression, restricted cubic spline (RCS) models, and Kaplan-Meier (KM) survival curves were used to analyze the association between metabolic equivalent of task (MET) and all-cause mortality in sarcopenic individuals. Additionally, random survival forest (RSF), Spearman correlation models, and receiver operating characteristic (ROC) curves were employed to evaluate the prognostic value of LPA, OPA, and TPA. A total of 4,936 participants were included, of whom 676 were diagnosed with sarcopenia, with 98 all-cause deaths occurring among individuals. After adjusting for confounders, LPA (OR = 0.316, 95% CI: 0.224–0.444, p \u3c 0.01), OPA (OR = 0.133, 95% CI: 0.090–0.196, p \u3c 0.01), and TPA (OR = 0.542, 95% CI: 0.387–0.759, p \u3c 0.01) were significantly associated with a lower prevalence of sarcopenia in healthy individuals. However, in sarcopenic individuals, higher levels of LPA in the fourth quartile (HR = 2.545, 95% CI: 1.072–6.043, p \u3c 0.05) and TPA in the third quartile (HR = 3.330, 95% CI: 1.347–8.232, p \u3c 0.01) were significantly associated with an increased risk of all-cause mortality. RCS models revealed a nonlinear relationship between LPA and TPA with all-cause mortality (p \u3c 0.05). The RSF model further demonstrated that LPA, OPA, and TPA have prognostic value in predicting all-cause mortality among sarcopenic individuals. This study suggests that daily LPA (\u3e2440 MET·min/week), OPA (\u3e5040 MET·min/week), and TPA (\u3e1460 MET·min/week)prevalence of sarcopenia in healthy individuals. However, in sarcopenic individuals, higher levels of physical activity, particularly LPA (1457–2440 MET·min/week) and TPA (693–1460 MET·min/week), were associated with an increased risk of all-cause mortality
A028: Therapeutic Exercise Management in Adolescents with Cam Morphology Femoroacetabular Impingement Syndrome: A Literature Review
No full textFemoroacetabular impingement is a common cause of hip pain in adolescents. Compared with the pincer-type, the incidence of cam-type is more common in asymptomatic adolescent patients. At present, there is much research on the treatment of FAI by arthroscopic surgery, and it has been shown that it has a positive intervention effect. However, there is little research on therapeutic exercise and a lack of normative understanding. The purpose of this review is to provide clues and ideas for the treatment of adolescents with cam FAI by summarizing the research results of therapeutic exercise management of FAI. We searched the articles in PubMed, Web of Science, CNKI, WanFang, WeiPu with the key words of “Femoracetabular Impingements”, Rehabilitation Exercise , CAM in Chinese and English, respectively. Repetitive literature and those that were not closely related to the purpose of this study were eliminated, and finally, 25 articles were included for review. Therapeutic exercises that adolescents with cam FAI can perform include patient education and movement adjustment, postural exercise, hip Strength exercise, core stabilization exercise, flexibility and mobility exercise, etc. In addition, the effectiveness of WMW and pelvic tilt correction has yet to be demonstrated. Through this review, it was found that there are the following deficiencies: (1) There are few high-quality studies on therapeutic exercise, and the follow-up period of the studies is short, and the number of samples is small, so the reliability of the treatment results needs to be verified. (2) There is no study on the difference in damage under different types of FAI. (3) There are no therapeutic exercise management programs for different types of FAI. (4) As a special population, adolescents have no standardized and targeted therapeutic exercise management. (5) In terms of physical impairments, there are contrary findings; more high-quality studies are needed. (6) Impairments in adolescents with FAI require further confirmation. (7) The duration of therapeutic exercise is uncertain
A185: Muscle Responses of Neck Whiplash Injury During Different Loads of Front Impacts
No full textWhiplash injury is a common neck injury caused by frontal collisions during sports. While muscle activation patterns during impact are critical to injury mechanisms, how cervical and lumbar electromyographic (EMG) responses scale with collision intensity remains unclear. This investigation compares neck and low-back EMG profiles under incremental impact intensities, providing biomechanical insights to optimize protective strategies for high-risk populations exposed to dynamic acceleration environments. 35 male subjects were selected. Age range: 19-22 years old; height: 173.6 ± 4.1cm; weight: 70.2 ± 6.4kg. Front impact was simulated on a specific testing apparatus by applying forward traction along the head with three different loads: 2.5 kg, 5 kg, and 7.5 kg. The height of vertical collision is 10cm. An electromyographic(EMG) system (Delsys, USA) was used for recording the muscle-- bilateral Erector Spinae(ES), Trapezius(TR), sternocleidomastoid (SCM), splenius capitis (SC)-- activity at a rate of 2000 Hz. Python 3.1.1 was used to analyze the EMG data. A bandpass filter was used (20–450 Hz, 4-pole Butterworth). Maximum voluntary isometric contractions (MVC) were used for data standardization. The indicators were the root mean square (RMS), mean power frequency (MPF), and integral electromyographic (iEMG). SC：2.5kg：RMS=2.75±4.17, MPF=62.99±10.4, iEMG=1.75±2.99; 5kg：RMS=3.38±5.71, MPF=67.14±8.24, iEMG=2.53±4.6;7.5kg：RMS=4.06±5.62, MPF=69.82±7.01; iEMG=2.71±3.93. TR：2.5kg: RMS=0.48±0.5, MPF=69.74±11.68, iEMG=0.32±0.51; 5kg: RMS=0.46±0.43, MPF=73.09±9.34, iEMG=0.34±0.42; 7.5kg: RMS=0.5±0.38, MPF=73.13±11.61, iEMG=0.41±0.43. SCM-L: 2.5kg: RMS=5.74±5.83,MPF=64.62±9.42, iEMG=3.67±3.91; 5kg: RMS=6.79±7.1, MPF=63.38±10.1, iEMG=4.62±5.43; 7.5kg: RMS=6.04±5.7, MPF=69.82±12.68, iEMG=4.57±4.67. ES：2.5kg: RMS=0.99±1.34，MPF=65.67±10.18, iEMG=0.56±0.67; 5kg: RMS=1.17±2.37, MPF=65.99±7.83, EMG=0.75±1.3; 7.5kg: RMS=1.88±4.42, MPF=65.33±9.41, iEMG=1.73±5.5. Repeated measures ANOVA is used to assess muscle metrics across various positions and intensities. RMS (load: p=0.001, η^2=0.011; muscle: p \u3c 0.001,η^2=0.168; load*muscle: p=0.219,η^2=0.010), MPF (load: p=0.001, η^2=0.028; muscle: p=0.025,η^2=0.036; load*muscle: p=0.181,η^2=0.027). iEMG (load: p \u3c 0.001, η^2=0.016; muscle: p \u3c 0.001, η^2=0.135; load*muscle: p=0.206, η^2=0.015). 1) Within a certain range of collision intensity, the activation response characteristics of the human neck and waist increase with increasing intensity. 2) There is no interaction effect between muscle position and load
A186: Evaluating Badminton-Specific Court Testing: A Systematic Review
No full textBadminton, a technically and tactically demanding sport, requires rapid reaction, eye-hand coordination, and agility, alongside both aerobic and anaerobic energy system capabilities. However, current mainstream fitness assessments primarily rely on non-specific and semi-specific tests, which, while reliable, lack ecological validity in capturing the multidimensional demands of badminton. Field-based tests, designed to simulate the sport-specific movements and energy demands, are critical for accurately evaluating badminton athletes\u27 performance. This systematic review aims to evaluate the reliability, validity, and applicability of existing field-based tests for badminton athletes, providing evidence-based insights for the development of more contextually relevant assessment methods. Method: Using keywords such as “badminton”, “specific”, and “test”, we searched multiple databases such as PubMed, Web of Science, Embase, and SPORT Discuss Full Text in November 2024. The inclusion criteria : (1) Study participants must be healthy, physically active, and fully functional badminton players of any age and gender; (2) Testing must occur on a badminton court or equivalent-sized site; (3) The assessment must simulate actual game demands, including specialized footwork and batting styles; (4) Research must be published in peer-reviewed English journals. A total of fifteen articles were included in the current study, involving a total of 7 endurance tests, 8 agility tests, including 5 changes of direction (no decision) tests. All studies involved 2–4 levels of interventions. Participants included males and females, with ages ranging from 10.3 to 34.4 years, and playing experience ranged from at least 1 year to 19.1 years of experience. Findings showed that the 13 tests demonstrated high reliability and validity, with only two tests (one endurance test and one COD test) considered ineffective for assessment purposes. Based on the studies reviewed, it seems that most tests serve as effective evaluation tools, they have limitations. Agility tests predominantly focus on horizontal displacement rather than spatial movement, and endurance tests often rely on single metrics, lacking multidimensional assessment. Additionally, specific on-court tests lack a universally accepted gold standard, complicating validity assessments. In practical applications, court-specific tests should be combined with traditional assessments to provide a comprehensive evaluation of athletes\u27 performance
A217: The Empirical Study on the Influence of After-School Football Training on School Students\u27 Social Integration
No full textThis study aims to demonstrate the importance of after-school football training in the socialization and integration process of primary school students. Method: Fifty primary school students were randomly assigned to an experimental group and a control group. The experimental group underwent a systematic and planned 9-week after-school football training intervention, while the control group continued with their normal school activities and did not participate in regular physical exercise during the same period. The sociometric method was employed, with pre-test and post-test questionnaires completed to compile interpersonal relationship matrices, indices related to personal status, and interpersonal relationship analysis charts for both groups. Results: Analysis of the group relationships within the experimental and control groups revealed that the two groups had the same level of cohesion pre-test. Post-test, the cohesion index of the experimental group increased, transforming from a weakly cohesive group to a strongly cohesive group. In contrast, the cohesion index of the control group remained unchanged, staying as a weakly cohesive group. There was a significant difference in the cohesion index between pre-test and post-test within the experimental group (p \u3c 0.05), and a significant difference was also observed between the experimental and control groups post-test (p \u3c 0.05). The research findings indicate that after-school football training has a positive impact on the socialization and integration process of primary school students
