Analysis of changes in lower limb joints of athletes during the movement of wild horses’ mane parting based on biomechanics

In the era of fitness, more and more young people are familiar with Taijiquan, a kind of physical fitness exercise. By conducting biomechanical analyses of the movements of Taijiquan, it is possible to exercise the body better. Numerous techniques in Taijiquan make it difficult to study each individually. Therefore, this paper studied the movement of “wild horses’ mane parting” in terms of biomechanics by analyzing the joint angle, stiffness, and impulse during this movement. Twenty male athletes were selected as subjects and divided into a professional group and a beginner group according to their training periods. High-speed cameras were used to shoot the “wild horses’ mane parting” movement. The angles of lower limb joints in these athletes were measured to calculate joint impulse and stiffness. The results showed that, compared with the professional group, there were significant differences in the adduction and abduction angle and the internal and external rotation angle between the beginner group and the professional group in the single-leg support movement stage (P< 0.05). There were also significant differences in joint impulse and stiffness (P< 0.05). Compared with beginners, long-term professional practitioners can make their movements more standardized. By comparing movements and data analysis, beginners can make their movements more standardized when practicing Taijiquan and avoid the risk of sports injury. The novelty of this article lies in the use of high-speed cameras to capture athletes’ movements, enabling accurate analyses of their joints and providing effective references for precise training.

Importance of Sports Activity for the Better Mental Health of the Indian Student

Physical activity, beyond its well-documented benefits for physical health, plays a crucial role in enhancing mental well-being. Research suggests that individuals with sedentary lifestyles exhibit higher morbidity rates and increased healthcare expenditures. In response to these challenges, exercise therapy is often recommended as an effective intervention for maintaining mental health. Empirical studies have consistently established a positive connotation between physical activity and various mental health outcomes. Notably, nonclinical investigations highlight that regular exercise significantly enhances self-concept and body image. This review aims to summarize current physiological and psychological mechanisms by which exercise contributes to mental well-being. One of the primary physiological pathways involved is the regulation of the hypothalamus-pituitary-adrenal (HPA) axis, which plays a serious role in stress reply. While exercise has been shown to alleviate indications of depression and anxiety, its effects appear to be more pronounced in clinical populations than in the general public. Multiple theoretical models have been projected to explicate the relationship between physical fitness and mental health.

Early resilience and epigenetic ageing: Results from the prospective Young Finns Study with a 31-year follow-up.

Evidence is accumulating on the connection of early adversities and harsh family environment with epigenetic ageing. We investigated whether early psychosocial resilience is associated with epigenetic ageing in adulthood. We used the population-based Young Finns data (n = 1593). Early psychosocial resilience was assessed in 1980-1989 across five broad domains: (1) index of psychological strength (self-esteem at home/in general/at school, perceived possibilities to influence at home, internal life control), (2) index of social satisfaction (perceived support from family/friends and life satisfaction), (3) index of leisure time activities (hobbies and physical fitness), (4) index of responsible health behaviors (infrequent smoking or alcohol consumption), and (5) index of school career (school grades and adaptation). Epigenetic ages were calculated for blood samples from 2011, and the analyses were performed with variables describing age deviation (AgeDevHannum, AgeDevHorvath, AgeDevPheno, AgeDevGrim) and DunedinPACE. Covariates included early family environment, polygenic risk scores for schizophrenia and major depression, adulthood education, and adulthood health behaviors. All of the early resilience indexes were associated with lower levels of epigenetic ageing in adulthood, most consistently with AgeDevGrim and DunedinPACE. The associations of psychological strength and social satisfaction, in particular, seemed to be non-linear. In a smaller subsample (n = 289), high early resilience was related to lower AgeDevGrim over a 25-year follow-up in those who had high "baseline" levels of AgeDevGrim. In conclusion, early resilience seems to associate with lower level of epigenetic ageing in adulthood. Our results tentatively suggest that early resilience may increase "equality in epigenetic ageing" in a general population.

Time junior middle school students invested to sports and their cognitive skill development: a time economics perspective

Great importance is attached to physical exercise and students’ cognitive development, yet the precise mechanism linking the time duration of physical activities or sports with adolescents’ cognitive development remains inconclusive. Based on the two-wave panel data of China Education Panel Survey (CEPS), this paper empirically examines the impact of daily physical exercise duration on junior middle school students’ cognitive abilities, by using the two-way fixed-effect estimation. The findings reveal a nonlinear relationship, specifically an inverted “U”-shaped pattern, between daily time length of physical activities or sports and students’ cognitive performance. The cognitive benefits of time investment in physical activities or sports reach the peak at approximately 0.829 h (equivalent to 50 min) per day among the teenagers in China. Furthermore, the daily time allocated to physical activities or sports affects students’ cognitive performance differentially, students attending rural schools were rewarded more progressively, students of poorer physical fitness and those in good shape did not show discernible between-group differences. This study shades light on educational governance and time management, urging school administrators, parents and students to optimize the efficiency and utility of time resource invested in sports activities.

The Impact of Interactive Video Games Training on the Quality of Life of Children Treated for Leukemia.

The study aimed to assess the impact of interactive video games (IVGs) as a form of physical activity (PA) on the quality of life. The study used a quality-of-life questionnaire (KIDSCREEN-10) and the HBSC questionnaire. In order to determine individual IVGs training parameters, an initial assessment of cardiorespiratory fitness level was performed, using the Cardio Pulmonary Exercise Test-Godfrey's progressive protocol. Children in the intervention group participated in 12 interval training sessions using IVGs (Microsoft's Xbox 360 S console with Kinect,). The study included 21 patients (7-13 years old; 12 boys and 9 girls) treated for acute lymphoblastic leukemia (n = 13) and acute myeloid leukemia (n = 8). Before the IVGs, all children had insufficient PA levels (90% of children in the intervention group and 90.91% of children in the control group did not engage in any PA during the last 7 days). After the intervention, 80% of the children in the IVGs group undertook PA lasting at least 60 min a day, three times a week. They exhibited better well-being, a subjective feeling of improved physical fitness (p < 0.0001), a greater subjective sense of strength and energy (p < 0.0001), and less feeling of sadness (p = 0.0016) than the children from the control group (p = 0.0205). The results of our study confirmed that an attractive form of virtual game or sport is willingly undertaken by children undergoing cancer treatment, and has significant benefits in improving the quality-of-life parameters. There is a clear need to create specific recommendations and rehabilitation models for children with cancer.

High-intensity interval swimming improves cardiovascular endurance, while aquatic resistance training enhances muscular strength in older adults

The aim of this study was to examine the effects of free swimming (FS), aquatic resistance training (ART), and their combination (FS&ART) on the body composition, blood pressure, and physical fitness of older adults. The study employed a randomized controlled design, comparing three experimental groups with a control group. Eighty volunteers aged between sixty and seventy years (age: 66.2 ± 2.3 years; body mass index: 25.8 ± 4.3 kg/m²) participated in the 16-week intervention, consisting of two weekly sessions. Assessments were conducted at baseline and post-intervention, including anthropometric measurements, blood pressure readings, and the Senior Fitness Test. Significant differences were found between groups in post-intervention considering the chair stand test (p = 0.017; ES = 0.125), arm curl test (p = 0.029; ES = 0.111), 8-foot up and go test (p = 0.042; ES = 0.102), and walk test − 6 min (p = 0.005; ES = 0.156). Specifically, both ART (+ 20.1%; p < 0.05) and FS&ART (+ 19.5%; p < 0.05) showed significantly greater improvements in the chair stand test compared to the control group. Similarly, ART (+ 23.1%; p < 0.05) and FS&ART (+ 18.7%; p < 0.05) performed better than the control group. FS&ART also exhibited a significant improvement over the control group in the 8-foot up-and-go test (+ 14.6%; p < 0.05). In the 6-minute walk test, FS (+ 19.4%; p < 0.05) and FS&ART (+ 15.9%; p < 0.05) both significantly outperformed the control group. This study found that FS improves cardiovascular endurance, while ART enhances muscular strength and endurance in older adults, with combined benefits for agility, suggesting integration of combined modalities into community wellness initiatives for enhanced physical fitness and health outcomes.

Bodily Distress Syndrome Is Associated with Impaired Physical Fitness-A Population Based Cross-Sectional Study (DanFunD).

Background and Aim: Functional somatic disorders (FSDs) are a unifying diagnosis that includes functional somatic syndromes (FSSs) as well as the unifying diagnostic construct of bodily distress syndrome (BDS). FSDs are characterized by persistent and troublesome physical symptoms that are prevalent across all medical settings and for which no clinical tests can establish a definitive diagnosis. The aim of this study was to explore associations between BDSs and objective measurements of body composition, cardiorespiratory health, and physical performance. Methods: Analyses are based on data from the Danish population-based cohort study, DanFunD, comprising data on 9656 participants aged 18-76 years and BDS case status, which was established using self-reported questionnaires. Adjusted multiple linear regression analysis was employed to evaluate associations between BDS and different measures of body composition, cardiorespiratory health, and physical performance assessed as part of a general health examination. Results: Compared to controls, individuals with single- or multi-organ BDS exhibited less optimal body compositions characterized by a higher BMI and fat percentage and larger waist circumference, as well as impaired cardiorespiratory health and reduced physical performance (lower maximal oxygen consumption and lower hand grip strength). Further, individuals categorized with multi-organ BDS had a less healthy body composition, lower cardiorespiratory health, and lower physical performance compared to individuals with single-organ BDS. Conclusions: In this cross-sectional study, we found BDS to be associated with suboptimal body composition, impaired cardiorespiratory health, and reduced physical performance. Individuals with multi-organ BDS tended to exhibit lower physical fitness or reduced cardiorespiratory health than individuals with single-organ BDS.

Temporal trends in weight-based disparities in physical fitness of children: 30-years of continuous surveillance through Slovenian national system

BackgroundObesity in childhood has deleterious consequences for health while improving physical fitness can significantly reduce health risks related to high body mass index. We aimed to examine the evolution of disparities in physical fitness based on weight status among 7–15-year-olds in Slovenia between 1989 and 2019 and compare these trends across sex, age and socioeconomic status.MethodsWe used annual data collected within the SLOfit monitoring system in the period between 1989 and 2019, totalling 4,256,930 participants (about 137 000 per year). We examined cardiorespiratory fitness (600-m run test), muscular fitness (60-s sit-ups, bent arm hang, and standing broad jump test) and skill-related fitness (backwards obstacle course, 60-m dash, arm plate tapping). We grouped children according to the IOTF cut-offs for BMI to those living with normal weight or excess weight and estimated changes in physical fitness over time by fitting quantile regression models separately by sex and age group, and then using segmented regression to identify the patterns of trends over time.ResultsWeight-based disparities in physical fitness were large in 1989 and have further increased by 2019. The increase in disparities was generally around 5 percentiles larger in boys, and 10–15-year-olds compared to younger children. It was particularly pronounced for body core strength and speed in boys (up to 15 and 19 percentiles, respectively) and upper body strength and speed among girls (up to 13 percentiles). Most of the increase in disparities in health-related fitness accumulated during the 2010s, when the fitness of children generally improved, but much less so in children living with excess weight.ConclusionsDespite recent improvements in population fitness levels, children with excess weight seem to be left behind, which adds to existing health inequalities. Our results should encourage policymakers to redesign policies aimed at promoting physical activity and enhancing physical fitness to make them more equitable and ultimately lead to reducing inequalities in fitness.

The Impact of Exercise Load and Intensity on the Performance of China U24 3x3 Women Teams

This study analyzed the exercise load and exercise intensity of the China U24 3x3 women team in multiple games, combined with the performance data of the players in the game, and explored the impact of these factors on exercise performance. The results showed that there was a significant positive correlation between load intensity and average heart rate, and high load intensity usually led to a higher average heart rate. In addition, performance data such as scoring and rebounding were also significantly correlated with load intensity and load volume. Players with higher scores often underwent higher load volume and load intensity in the game. This shows that in high-intensity games, players' physical fitness and performance are closely related, and reasonable monitoring and management of load intensity are crucial to improving player performance and reducing the risk of injury. The study also showed that there were significant differences in load volume and load intensity between the U24 Blue Team and the U24 Red Team in different games, further emphasizing the importance of load management in game strategy and physical training. This study provides empirical evidence for basketball teams to formulate scientific training plans and game strategies, and emphasizes the importance of exercise load and intensity management to improve the overall performance of the team and the individual performance of the players.

Developmental patterns of athletic performance and physical fitness in youth baseball players: A longitudinal analysis

ABSTRACT This study aimed to evaluate developmental patterns in athletic performance during youth and determine their association with changes in physical fitness. The testing included three athletic performance (i.e. ball speed in pitching, swing velocity in batting, 30-metre sprint time) and two physical fitness tests (i.e. medicine ball [MB] back throw and modified star excursion balance test [SEBT]). Data from 235 players (557 measurements) aged 6 to 14 were eligible for a longitudinal evaluation. The statistical analysis was based on the latent growth curve models of the athletic performance development process and the random-effect panel data multivariate regression analysis for ball speed, swing velocity, and 30-metre sprint time. The 30-metre sprint time showed a small curvature but an accelerated increase around 12‒13 years old. However, the ball speed, swing velocity, and modified SEBT demonstrated a slower or less accelerated change in the developmental pattern starting around 12‒13 years old. Multivariate longitudinal analysis revealed that developmental change in athletic performance was positively associated with age and MB back throw. Our findings highlight the developmental patterns of athletic performance associated with baseball exhibiting stagnation as well as acceleration, which may help develop effective age-appropriate strategies for improving performance in youth baseball players.

Martial Arts in Physical Education and Student Self-Regulation

This study explores the impact of martial arts education within the physical education curriculum, aiming to assess its effectiveness in enhancing students' cognitive, affective, and physical self-regulation, while also identifying areas for improvement. Quantitative data from student surveys indicated that martial arts education has a positive effect on self-regulation across all domains. However, qualitative responses revealed significant challenges, including accessibility issues, the need for a more practical and engaging curriculum, and insufficient support from schools and facilities. Based on these findings, a comprehensive program was developed to address these concerns. The program focuses on curriculum enhancement, increasing accessibility and engagement, improving facilities and resources, supporting instructor development, and establishing ongoing assessment mechanisms. The program’s implementation plan is structured across six phases, ensuring a strategic approach to achieving the intended outcomes. The study concludes that while martial arts education holds considerable potential for holistic student development, its full impact is currently limited by various barriers. By addressing these challenges through targeted interventions, educational institutions can maximize the benefits of martial arts education, fostering not only physical fitness and discipline but also cultural appreciation and emotional resilience among students. The proposed program serves as a roadmap for schools to enhance martial arts education and better align it with educational objectives, ensuring a more engaging and impactful learning experience.

Determining the Fitness Level of People with Down Syndrome Living in Kosovo Based on the ALPHA Protocol

Purpose: This study aimed to establish national norm values for body composition and fitness levels among individuals with Down syndrome. It also aimed to investigate gender differences in body composition features and fitness parameters, analyze the impact of the region where individuals with Down syndrome reside, and compare their fitness levels with international peers. Methods: The sample included 81 participants, 40 females (height: 146.6±4.88 cm, weight: 63.6±16.4 kg) and 41 males (height: 157.4±6.21 cm, weight: 66.8±14.8 kg). To assess the physical fitness levels of the participants with Down syndrome, a modified version of the ALPHA testing protocol was used. Findings: The results demonstrated significant gender differences (p&amp;lt;0.05) in body composition and fitness parameters, with males generally exhibiting better outcomes compared to females. Moreover, significant disparities (p&amp;lt;0.05) in body composition and fitness parameters were observed among individuals with Down syndrome residing in different regions of Kosovo. Noteworthy gender disparities exist in terms of body composition and physical fitness metrics, with male participants achieving superior results compared to their female counterparts. Furthermore, noticeable variations were observed among the regional Down syndrome centers, with participants from older centers displaying improved fitness metrics and body composition features compared to those from newly established facilities. Conclusion: Gender differences in body composition and fitness were evident, with males outperforming females, except in muscle mass. Future studies should explore fitness and health barriers in Kosovo's DS population, with a focus on improving physical activity through tailored strategies.

Soil-transmitted helminthes prevalence, intensity, and associated factors among school-aged children in the communities of west Guji Zone, South Ethiopia

BackgroundSoil-transmitted helminth (STH) infections are a major health problem among school-age children in developing countries. Prolonged exposure to STH can lead to reduced physical fitness, stunted growth, anemia, bowel obstruction, and cognitive impairments. ObjectiveTo determine the prevalence, intensity, and associated risk factors of soil-transmitted helminths among school-aged children in the west Guji Zone, South Ethiopia. MethodsA community-based cross-sectional study was conducted among 614 randomly selected school-aged children in selected districts of the West Guji zone from February to March 2023. A pre-tested questionnaire was used, and samples were examined by wet mount and Kato-Katz techniques. Data entry was analyzed using SPSS. Binary and multivariable logistic regression analyses were applied to identify potential associated factors. P-value<0.05 was declared as statistical significance. ResultsThe overall prevalence of STH was 32.7 % (95 % CI: 28.4%–35.8 %). Ascaris lumbricoides 95 (11.1 %) was the most common identified STH. Most school-age children, 74 %, were infected with a mild intensity of soil-transmitted helminths (STH). The mean egg count for Ascaris lumbricoides, Trichuris trichiura, and hookworms was 4465.4, 563.7, and 958.9, respectively. The study found significant associations with several factors, including washing hands with soap after using the toilet (AOR: 2.8, 95 % CI: 1.8–4.6), trimming fingernails (AOR: 4.6, 95%CI: 2.9–7.1), and the habit of wearing shoes (AOR: 2, 95%CI: 1.4–2.9) ConclusionSoil-transmitted helminths infection prevalence is high among school-aged children of the study areas. To prevent and control these infections, comprehensive health education should focus on the importance of hygienic practices, improved sanitation, and regular deworming programs for school-aged children.

Effects of soccer instruction on the executive functions and agility of children in early childhood.

Studies have shown that in open-skill sports the executive function of high-performing players is significantly higher than that of the control group. However, whether participation in soccer effectively improves executive function is unclear because previous studies lacked baseline measurements of executive function. Furthermore, agility, mostly developed in early childhood, is the most demanding component of physical fitness in open-skill sports, requiring sudden changes in body direction while running at full speed. However, no studies have examined the improvement in agility of young children participating in open-skill sports through comparison with a control group. This study aimed to clarify whether instruction in soccer, an open-skill sport, can effectively improve the executive function and agility of kindergarteners compared to a control group. In April 2020, 31 five-year-old children enrolled in kindergarten K in H prefecture in Japan were targeted as the intervention group and received soccer instruction for 12 weeks. In April 2020, a control group was established, consisting of 39 five-year-old children enrolled at the same kindergarten. Participants in both groups were measured for agility, inhibition, and working memory before and after (pre-post) soccer instruction for the intervention group. For each item, a two-way ANOVA of the group (intervention group・control group) x measurement period (pre-post) was performed, showing no significant interactions for working memory and agility. Because only the inhibition effect was significant, simple main effects were tested. Regarding inhibition, although the intervention group (M = 0.18, SD = 0.01) and the control group (M = 0.17, SD = 0.01) did not differ significantly in performance pre-intervention, the intervention group (M = 0.23, SD = 0.01) showed significantly better performance post-intervention compared to the control group (M = 0.19, SD = 0.01) (p < .01). Thus, soccer instruction improved kindergarteners' inhibition, to a level significantly higher than that of the control group. Still, no differences were found between groups regarding working memory and agility.

A Study of Hypertension and Fitness of Individuals with Spinal Cord Injury: A Cross-Sectional Study.

Background/Objectives: Individuals with spinal cord injuries have a higher incidence of chronic conditions such as hypertension and cardiovascular diseases due to a sedentary lifestyle and low levels of physical activity caused by their disability. Additionally, their physical fitness levels are lower compared to those without disabilities. This cross-sectional study aimed to investigate the relationship between hypertension and the fitness of individuals with spinal cord injuries in South Korea while considering differences across sexes and spinal cord injury levels. Methods: This study used data for 835 individuals with spinal cord injuries aged 20-64 years who visited the Korea Paralympic Committee fitness standard test centers from 2018 to 2022, obtained from the Korea Culture Information Sports Association's big data market. The data were analyzed using a series of t-tests, a one-way analysis of variance, a logistic regression analysis, and the four-quartile method. Results: The prevalence of hypertension was 24.4%, and it was different according to the spinal cord injury impairment level. A lower grip strength, a lower arm curl, and a higher body mass index were associated with increased blood pressure. Conclusions: Therefore, a high level of physical strength in people with spinal cord injuries is thought to contribute to lowering blood pressure.

Lifestyle Behaviours in Pre-Schoolers from Southern Spain-A Structural Equation Model According to Sex and Body Mass Index.

The present study aimed to examine the relationship between screen time (ST), sleep time (SLT), physical fitness (PF), Mediterranean diet (MD) adherence, eating behaviours, and body mass index (BMI) in a sample of pre-schoolers from Granada (Spain). In order to address this aim, an explanatory model was developed to examine existing relationships between ST, SLT, PF, MD, pro-intake (PRO-I) and anti-intake (ANT-I) behaviours, and BMI. Further, the proposed structural model was examined via multi-group analysis as a function of sex and BMI. A cross-sectional study was conducted with 653 three- to six-year-old pre-schoolers attending 18 different schools invited to take part in the present study. Structural equation modelling (SEM) was employed to analyse relationships between study variables as a function of sex and BMI. SEM analysis revealed negative associations between ST and PF (p < 0.005), ST and MD adherence (p < 0.005), ST and SLT (p < 0.005), MD adherence and ANT-I behaviours (p < 0.005), and MD adherence and BMI (p = 0.033). In contrast, positive associations emerged between SLT and MD adherence (p < 0.005), and PRO-I behaviours and BMI (p < 0.005). SEM revealed differences according to sex and BMI. The study highlights significant relationships between lifestyle behaviours and physical and dietary outcomes in pre-schoolers from southern Spain, with variations based on sex and BMI. These findings suggest the need for interventions aimed at reducing ST and promoting better sleep, PF, and dietary habits in order to limit weight-related and general health risks in pre-schoolers from southern Spain.
