Are physical activity and/or adherence to the Mediterranean diet determinants of the changes found in kinanthropometric variables, body composition and physical fitness in adolescents?

The practice of physical activity and adherence to the Mediterranean diet (AMD) have been extensively studied for their relationship with kinanthropometric, body composition and physical fitness variables. However, no previous study has analyzed whether these healthy habits are equally determinant for the differences found in kinanthropometric, body composition and physical fitness variables or, on the contrary, if one of them is more relevant. For this reason, the objectives of the present study were: (1) to analyze the differences in kinanthropometric, body composition, and physical fitness variables between adolescents with different levels of physical activity and AMD, and (2) to determine whether physical activity and/or AMD are predictors of differences in kinanthropometric variables, body composition or physical fitness in adolescents. The sample consisted of 791 adolescents (404 males and 387 females; mean age: 14.39±1.26 year-old) whose physical activity level, AMD, kinanthropometric variables, body composition and physical fitness, were measured. The results showed differences when considering the level of physical activity in kinanthropometric variables, body composition and physical fitness, but not the level of AMD, which was relevant only when it was poor, and the adolescents were inactive. Nevertheless, the AMD did not seem to exert such a determining effect as to produce significant differences on its own. On the other hand, the practice of physical activity did act as a predictor mainly of changes in the fitness variables. Therefore, the main novelty of the present study is the establishment of an order of importance of the healthy habits acquired by adolescents, concluding that the practice of physical activity is more determinant for the differences found in the study variables.

Evaluating pelvic floor muscle activity in chronic functional constipation: A transabdominal ultrasound study

IntroductionChronic functional constipation (CFC) is one of the most challenging types of constipation which negatively influences patients’ quality of life. Recently, investigators mentioned pelvic floor muscles (PFMs) as an influential factor in the symptoms of patients with CFC, while its underlying mechanism is still unclear. The aim of this study is to investigate the PFMs function in people with and without CFC using transabdominal ultrasound. MethodIn this cross-sectional and prospective study, we utilized a convenience sample of 200 individuals (100 CFC and 100 non-CFC) aged between 20 and 50 years old. The data collection included the measurement of the bladder base diameters displacement between rest and contraction using transabdominal ultrasound in all subjects. Also, individuals’ diet and physical activity were assessed as contributing factors using International Physical Activity Questionnaire and Food Frequency Questionnaire. ResultsThe result of MANCOVA revealed no significant group by physical activity level interaction for bladder base diameter at rest and bladder base displacement. Moreover, the Kruskal-Wallis test showed significant difference in physical activity level of patients with CFC in comparison with healthy individuals. Independent T-test results revealed that there is a significant difference in the consumption of fat and dairy subgroups between two groups. Discussion and conclusionsThe results indicated that there is no significant association between the bladder base displacement and the development of CFC. Moreover, our data revealed that people with CFC experience a more sedentary life and consume more fat and dairy products in comparison with individuals without CFC.

Physical activity and mental health of medical students.

Medical students usually do not meet the recommendations on the minimum level of physical activity, despite knowing the impact that physical activity has on the prevention and treatment of various diseases. Medical students are considered to be insufficiently physically active. The aim of this study is to determine the prevalence of physically active fifth-year medical students at five universities in Serbia, as well as to identify factors associated with insufficient physical activity of students. A cross-sectional study was performed in the population of fifth-year medical students from five different universities in Serbia. The research instrument was a questionnaire specially designed based on similar research. Descriptive and analytical statistics methods were used in statistical analysis. The study included a total of 573 fifth-year medical students from five universities in Serbia: 311 (54.3%) Belgrade; 86 (15.0%) Kragujevac; 58 (10.1%) Nis; 66 (11.5%) Kosovska Mitrovica; 52 (9.1%) Novi Sad. Insufficient physical activity was statistically significantly associated with studying at the University of Kosovska Mitrovica (OR = 3.98, 95% CI: 1.83-8.57). There was a statistically significant difference in the frequency of anti-anxiety medications use in the last 12 months between students with sufficient and insufficient physical activity (p = 0.040) as well as in the average number of cigarettes smoked per day between students with sufficient and those with insufficient physical activity (2.82 ± 6.35 vs. 4.50 ± 8.29, p = 0.043). There was also a statistically significant difference in the average score on the Beck's depression scale between students with sufficient and students with insufficient physical activity (6.51 ± 6.59 vs. 10.03 ± 9.37, p < 0.001) and in the average score on Zung's anxiety scale (34.86 ± 8.18 vs. 38.07 ± 8.71, p = 0.003). A high percentage of medical faculty students (86.6%) are physically active. Differences in the level of physical activity were observed between students of these five universities as well as between students with different levels of physical activity.

Impacts of active mobility on individual health mediated by physical activities

Active mobility, encompassing walking and cycling for transportation, is a potential solution to health issues arising from inadequate physical activity in modern society. However, the extent of active mobility's impact on individual physical activity levels, and its association with health as mediated by physical activities, is not fully quantified. This study aims to clarify the direct relationship between active mobility usage and individual health, as well as the indirect relationship mediated by physical activity, with a focus on varying levels of physical activity intensity. Utilizing data from the 2017 U.S. National Household Travel Survey (NHTS), we employed Poisson regression to predict active mobility usage based on socio-demographic and household socio-economic characteristics. A Structural Equation Model (SEM) was then used to investigate the direct and indirect effects of active mobility on individual health, mediated by physical activity. We further segmented individuals according to their intensity of physical activity to examine how such effect differs between different levels of physical activity. The study demonstrates that active mobility usage positively correlates with both the amount and intensity of physical activity. The effect of active mobility on individual health includes a direct positive effect (29% for intensity, 67.7% for amount) and an indirect effect mediated by physical activity (71% for intensity, 32.3% for amount). Notably, the mediation effect of active mobility on health is more substantial in the context of vigorous physical activities compared to light or moderate activities. Our findings reveal a significant positive influence of active mobility on individual health, encompassing both direct and indirect effects mediated by physical activities. These results quantitatively underscore the health benefits of active mobility and suggest the importance of promoting active mobility as a strategy to improve public health.

The effect of anthropometric measurements and muscle endurance of the trunk and lower extremities on anatomic body awareness in healthy individuals with different levels of physical activity.

The interaction between anthropometric measurements and muscular endurance and how these factors manifest in anatomical body awareness have not yet been fully investigated. It was aimed to examine the relationship between physical activity, body anthropometric measurements and endurance and anatomical body awareness in healthy individuals. A total of 217 individuals aged 19-40 participated in the study. Participants were categorized into inactive (n = 65), minimally active (n = 80), and sufficiently active (n = 72) groups based on the international physical activity questionnaire (IPAQ). Anthropometric measurements including shoulder, abdomen, waist, and hip circumferences were taken. Participants' trunk muscle endurance and lower extremity endurance was assessed through various tests. Anatomic body awareness was evaluated using the Body Awareness Questionnaire (BAQ) with established validity. While no significant difference in shoulder circumference measurements was found between the inactive and minimally active groups (p > 0.05), the sufficiently active group showed significantly higher shoulder circumference measurements compared to the other groups (p < 0.05). Significant differences were observed among all endurance tests between the groups (p < 0.05). Participants' body endurance increased significantly with higher activity levels. Moreover, anatomic body awareness exhibited significant variation among the three groups (p < 0.05), with the sufficiently active group having the highest level of anatomic body awareness. Positive correlations were found between all endurance tests and anatomic body awareness (p < 0.05), as well as a positive correlation between physical activity levels and anatomic body awareness (p < 0.05). It is suggested that physical performance and endurance increase anatomical body awareness when applied with appropriate treatment methods, can be applied for a healthier life and can be an additional application in the clinical environment.

Contribution of Nutritional, Lifestyle, and Metabolic Risk Factors to Parkinson's Disease.

Modifiable risk factors for Parkinson's disease (PD) are poorly known. The aim is to evaluate independent associations of different nutritional components, physical activity, and sedentary behavior and metabolic factors with the risk of PD. In this population-based prospective cohort study using the data of the United Kingdom Biobank (from 2006-2010), 502,017 men and women who were free from PD (International Classification of Diseases 10th edition; "G20") at baseline were included. We implemented a Cox proportion hazard's model to evaluate the associations of different levels of physical activity, sitting time, sleep habits, diet quality, alcohol and coffee consumption, smoking, and body mass index with PD risk, adjusting for several confounding variables. During a median follow-up of 12.8 years, lifestyle factors including vigorous physical activity (hazard ration [HR] = 0.84; 95% confidence interval [CI], 0.75-0.94), low-to-moderate sitting time (HR = 0.89; 95% CI, 0.81-0.97), and high sleep quality (HR = 0.89; 95% CI, 0.80-0.99) were associated with a reduced risk of PD. Small amounts of coffee (HR = 0.88; 95% CI, 0.82-0.95), red meat (HR = 0.86; 95% CI, 0.76-0.97), and current smoking (HR = 0.65; 95% CI, 0.56-0.75) were also associated with a lower risk of PD, whereas alcohol intake (HR = 1.29; 95% CI, 1.06-1.56) with higher PD risk. Secondary analysis, including metabolic risk factors, confirmed these findings and highlighted the potential protective effect of plasma vitamin D and uric acid, but of low-density lipoprotein-cholesterol, triglycerides, and C-reactive protein as well. Vigorous physical activity, reduced sitting time, good sleep quality together with small coffee intake and vitamin D supplementation are potentially neuroprotective lifestyle interventions for the prevention of PD. © 2024 International Parkinson and Movement Disorder Society.

Differences in nutritional status and level of physical activity among adolescents living in urban and rural areas of Montenegro - national study

BackgroundNutritional status and physical activity are important factors for adolescent health. These factors may vary by the place of residence. This study aims to assess the nutritional status and physical activity levels, as well as their variations by the place of residence.MethodsThe sample consisted of 1503 adolescents (46.3% male; 53.7% female), with a mean age of 15.7 ± 0.7 years. Nutritional status was assessed using Body Mass Index (BMI), Waist-to-Height Ratio (WHtR), and Body Fat Percentage (BF). Physical activity levels were assessed using the PAQ-C questionnaire. Differences in nutritional status among adolescents living in urban and rural areas were analyzed using Chi-square test (p ≤ 0.05), while differences in physical activity levels were analyzed using an independent samples t-test (p ≤ 0.05).ResultsIn terms of BMI, 14.7% of males were overweight and 10.1% were obese, while 12% of female adolescents were overweight and 3.1% were obese. There were no differences in nutritional status among adolescents living in urban and rural areas (BMI, WHtR, BF). Male adolescents in rural areas had significantly higher physical activity levels compared to urban areas (p = 0.032). They showed higher activity scores during a spare time (p = 0.002), physical education classes (p = 0.002), little breaks (p = 0.007), and lunchtime (p = 0.034). Female adolescents showed significance only in spare time activity (p = 0.020).ConclusionThe differences in nutritional status among adolescents living in urban and rural areas were not found. However, male adolescents living in urban areas showed lower physical activity levels than their rural counterparts. Strategies should be implemented to promote physical activity among adolescents in urban areas, and attention should be given to the further urbanization process to create improved conditions for engaging in physical activity.

Arthritis prevalence is associated with metabolic syndrome risk factors but not with physical activity in middle-aged and older patients - a cross-sectional study

BackgroundIn light of the aging population, increasingly suffering from the metabolic syndrome (MS), strategies need to be developed to address global public health challenges known to be associated with MS such as arthritis. As physical activity (PA) may play a crucial role in tackling those challenges, this study aimed to determine the association between the number of MS risk factors, PA and arthritis in people ≥ 50 years old.MethodsData from the Survey of Health, Ageing, and Retirement in Europe (SHARE) were used to estimate the prevalence of arthritis and MS risk factors in the European population ≥ 50 years and to evaluate the associations between MS risk factors, PA and arthritis. Binary logistic regression was performed to calculate the odds ratio of different factors.Results73,125 participants were included in the analysis. 55.75% of patients stated at least one of the three MS risk factors. The prevalence of rheumatoid arthritis (RA) and osteoarthritis (OA)/other rheumatism among ≥ 50 years population was 10.19% and 19.32% respectively. Females showed a higher prevalence of arthritis than males. Prevalence did not differ between groups with different levels of PA. Arthritis prevalence was positively correlated with the number of MS risk factors (P < 0.01) but not with PA (P > 0.05).ConclusionMiddle-aged and older Europeans with multiple comorbidities suffered from RA, OA or other rheumatism more frequently than participants with fewer comorbidities, while the level of physical activity was not associated with the number of metabolic risk factors in patients with RA and OA/other rheumatism.

Perceived academic self-efficacy of adolescents and the relationship with physical activity

Given the challenges and levels of competitiveness that exist at the educational level, it is necessary to analyze the different factors that determine academic effectiveness, in consideration of sedentary tendencies and the need for physical activation in the school-age population, research to determine the relationships between academic self-efficacy with physical activity is carried out in this population. Methods: to carry out this project, a sample of 248 secondary and high school students was used, from whom characteristic information was collected on the perception of academic self-efficacy, on physical activity carried out using accelerometer over seven days, as well as the analysis of factors such as travel and sports practice. Results: it is shown that the variables surrounding rest show a negative correlation with academic efficiency, while the different levels of physical activity show a greater positive correlation with academic self-efficacy. Conclusions: moderate physical activity and MVPA show a greater benefit in perceived academic self-efficiency, while the rest variables show a negative relationship with academic efficiency. Keywords: adolescents, academic self-efficacy, accelerometer, physical activity.

Comparison of the level of physical activity after the COVID-19 pandemic in Poland, Slovakia and the Czech Republic

BackgroundThe COVID-19 pandemic was associated with limited physical activity (PA) of most of the world’s population. This cross-sectional prospective study aimed to assess the levels of PA of university students in Poland, Czech Republic and Slovakia after COVID-19 using the International Physical Activity Questionnaire Short Form (IPAQ-SF).MethodsA total of 2635 students completed questionnaires regarding their PA levels using the IPAQ-SF between September and December 2022.ResultsPA measured by metabolic equivalent of task (MET) scores, varied between the three countries: Slovakia median MET-minutes/week score 4459.9; Czech Republic 3838.8 Poland 3567.1. The results of the post hoc analysis revealed there were significant differences in MET-minutes/week values between the Czech Republic and Poland (p < 0.035) as well as between the Czech Republic and Slovakia (p < 0.037). The analysis of energetic expenditure during walking revealed that students from the Czech Republic and Slovakia had higher median MET-min/weeks values (Czech 2284.1; Slovak 2467.1) compared to their Polish (1536.1) peers (p < 0.001). Polish cohort presented with significantly higher body mass index (BMI) (p < 0.001) than Czech and Slovak groups (BMI Czech: 22.3; Slovak 22.8; Polish 23.8).ConclusionsSignificant differences in PA levels between the Czech Republic, Poland, and Slovakia university students were identified. Slovakia showed the highest median PA measured as a MET score, and Poland showed the lowest. Compared to available pre-COVID studies it seems the total level of PA in the observed cohorts has not returned to the pre-COVID levels and students remain less active.

Physical Activity and its Correlates among University Students in Lahore

Background: Physical activity plays a crucial role in maintaining overall health, yet global trends indicate a decline in these levels among university students. Gender differences, environmental access, and lifestyle choices have been identified as significant factors influencing physical activity levels. Previous studies have offered insights into these dynamics, yet gaps remain in understanding the comprehensive impact of various determinants on physical activity among the youth. Objective: This study aimed to assess the levels of physical activity and their association with different factors among university students, with a focus on identifying gender disparities and the influence of environmental and lifestyle factors on physical activity levels. Methods: A cross-sectional study was conducted among students aged 18 to 30 years at Akhtar Saeed Medical and Dental College (AMDC) and the University of Lahore (UOL) from July 2022 to January 2023. Ethical approval was obtained, and a sample size of 150 students was determined using EPI software. Data on physical activity levels were collected using the International Physical Activity Questionnaire (IPA-Q) and analyzed using SPSS version 25. Chi-square tests were applied to assess the association between physical activity levels and factors such as computer game play, music listening, sports participation during school, parental encouragement, and institutional support. Results: Among the participants, a significant gender difference in physical activity levels was observed, with males engaging more in strenuous activities. The study found a high association of physical activity with being an active sportsman during school and college (Chi-Square = 7.194, P-value = 0.02) and listening to music (Chi-Square = 9.27, P-value = 0.01). A majority of the students fell into the mild physical activity category, with fewer participants involved in moderate and high physical activity levels. No significant association was found with computer game playing, parental encouragement, or institutional support for physical activity. Conclusion: The study highlights significant gender differences in physical activity levels among university students, with males being more active. Early sports involvement and music listening emerged as key factors associated with higher physical activity levels. The findings suggest the need for targeted interventions to enhance physical activity, particularly among female students, and promote a more active lifestyle within the university setting.

Study of regulation and adaptive capabilities of the cardiovascular system of young people with different levels of physical activity

The study of HRV of students indicates that regardless of the level of physical activity, young men had a more favorable type of regulation of the heart and high adaptive capabilities of the body. In students with a high level of physical activity, these differences are less pronounced.

Physical activity levels, gut permeability, circulating inflammatory cytokines and TLR4 signalling in PBMCs of COVID-19 patients

Physical exercise could confer some protection against the inflammatory cytokine storm induced by SARS-CoV-2 infection and against severe COVID-19 symptomatology. However, the mechanisms underlying this protective effect of exercise have not been elucidated yet. Therefore, the aim of this study was to investigate the activation of the inflammatory pathway in peripheral blood mononuclear cells (PBMCs) and to test a possible association between the regulation of this pathway and the expression of plasma inflammatory cytokine markers as well as with physical activity levels. All patients (n = 31; 21 males and 10 females) had at least three symptoms associated with COVID-19 and were recruited in the emergency unit. They were immediately tested for COVID-19 by polymerase chain reaction (COVID-19 n = 18, amongst which 9 were hospitalized and 9 quarantined; Non-COVID-19 n = 13) and a blood sample was collected. Physical activity levels were determined using the international physical activity questionnaire (IPAQ). No differences in physical activity levels nor sitting time were found between the COVID-19 and the Non-COVID-19 group. However, moderate to vigorous physical activity was lower in the hospitalized compared to the quarantined group. Toll-like receptor 4 (TLR4) and MyD88 protein expression in PBMCs was lower in the COVID-19 than in the Non-COVID-19 group. Moreover, TLR4 protein expression was lower in the hospitalized than in the quarantined subgroup. While no difference was observed in plasma zonulin levels between COVID-19 and Non-COVID-19 patients, quarantined patients had lower plasma zonulin levels compared to hospitalized patients. In conclusion, patients hospitalized with severe COVID-19 were less physically active and presented greater gut permeability and a downregulation of the TLR4 pathway in PBMCs compared to quarantined and Non-COVID-19 individuals. The lower expression of TLR4 could be a mechanism to prevent, or at least to mitigate, the inflammatory cytokine storm related to the severe form of COVID-19.

Association of Socio-Demographic Factors, Social Determinants of Health, and Weekly Physical Activity in an Urban Hospital in Northwest Indiana

Background: Engaging in regular physical activity has been proven to have beneficial health effects such as preventing chronic diseases and improving mental health. Recent studies have demonstrated correlations between socio-demographic factors and physical activity levels. This study determined the associations between socio-demographic factors, social determinants of health and the amount of weekly physical activity in patients occupying an urban underserved area.&#x0D; Methods: This study retrospectively analyzed a dataset generated by St. Mary Medical Center from EPIC™ with demographic characteristics and physical activity levels partitioned by time per week for adult inpatient visits from January 2021 to March 2023. Patients were stratified into physical activity levels based upon published guidelines: inactive (no physical activity), insufficiently active (&lt;150 minutes per week) or sufficiently active (≥150 minutes per week). Data analysis was conducted in SPSS 28.0 using tests of association including Kruskal Wallis H and multivariate ordinal regression model. This study was exempted by Indiana University Human Research Protection Program (IRB # 14040).&#x0D; Results: The sample of individuals from the dataset who answered physical activity questions was comprised of 1498 patients. There was a statistically significant difference in physical activity level by age group (p&lt;0.001), sex (p&lt;0.05), insurance category (p&lt;0.001), and social connections risk score (p&lt;0.001); with race (p=0.057) and language (p=0.054) approaching significance. Multivariate analysis showed that age was the only significant factor when accounting for all variables, with higher age groups reporting lower proportions of physically active individuals.&#x0D; Conclusion: Determining how socio-demographic factors influence physical activity levels will direct efforts to form and implement new interventions in the Northwest Indiana urban area and support community health initiatives. This data makes it possible to inform practitioners of the demographics that are at risk of being insufficiently active and having them direct those patients to programs in place to help bridge the lapse.

A153: The Relationships Between Physical Activity and Health-Related Quality of Life in Parent-Child Dyads with ASD

Purpose: Researchers have found that the core and combined symptoms of autism spectrum disorder (ASD) negatively influence the health-related quality of life (HRQoL) of autistic children and their parents. Although it is supported that participation in physical activity (PA) can enhance the HRQoL and well-being in general, few studies have addressed the relationship between HRQoL with PA in the population with ASD. This study examines how much leisure-time physical activity participation is correlated to HRQoL in parent-child dyads with ASD. Method: Participants were recruited from two Rehabilitation Centers for neurodevelopmental disability children. Eighty-five ASD children and their parents participated in this study. HRQoL for ASD children and their parents was measured with the World Health Organization Quality of Life short form (WHOQoL-26) and the Pediatric Quality of Life Inventory 4.0 (PedsQL 4.0, parent-report version) respectively, while leisure-time PA participation of both children and parents was assessed using the Godin Leisure-Time Exercise Questionnaire (GLTEQ). We first confirmed the psychometrics of the WHOQoL-26 and PedQL 4.0 and then analyzed the relationships between different levels of PA and HRQoL in dyads. Results: Descriptive statistics showed that 30.6% of ASD children (Mage=5.25±1.48; 85.9% boys) and 42.4% of their parents (75.3% between 31-40 years; 73 mothers and 12 fathers) were insufficiently active. For parents of children with ASD, the physical domain of HRQoL had a small positive correlation with light PA (r=0.27, p=0.013) while the psychology domain had a small to moderate positive correlation with moderate (r= 0.23, p=0.04), light (r=0.3, p=0.006), and total (r=0.23, p=0.032) PA. Also, the environment domain of HRQoL had a small positive correlation with moderate (r=0.28, p=0.011) and light (r=0.32, p=0.003) PA. Concerning ASD children, the physical domain of HRQoL had a small to moderate positive correlation with moderate (r= 0.24, p= 0.027) and total (r= 0.32, p= 0.004) PA. Furthermore, there were several interrelationships between parent-child dyads’ PA and parent-child dyads’ HRQoL. ASD children’s social domain in HRQoL was correlated to their parents’ light PA (r=0.25, p=0.021) whereas parents’ environment domain was correlated to their children’s mild PA (r=0.24, p=0.03). Conclusion: There are significant relationships between PA and HRQoL for both children with ASD and their parents. Particularly, the parent-child dyads’ HRQoL may benefit from each other’s leisure-time PA involvement. Due to ASD children’s restricted daily PA norm and their parent’s challenging caregiving environment, the designation of effective PA enhancement strategies may enhance the quality of life in both children with ASD and their parents.

A111: Relationship Between Physical Activity and Mental Toughness

Purpose: Physical activity has favorable impacts on exercisers' stress levels, psychological distress and anxiety, emotional regulation, and mental wellness. In recent years, the global outbreak of COVID-19 has subtly altered college students' lifestyles. Studies have shown that the physical and mental health of students has deteriorated dramatically, which is alarming. Mental toughness refers to the ability to adapt well in the face of major pressures, setbacks, and adversity in life. The purpose of the present study was to examine variations in mental toughness depending on the intensity, length, and frequency of physical activity. Methods: A total of 3,120 Chinese college students participated in this study. In the spring semester of 2022, participants were given the demographic questionnaire, the Physical Activity Rating Scale (PARS-3), and the Chinese version of the Mental Resilience Scale (CD-RISC). 3049 students completed the survey. Independent sample t test, one-way analysis of variance (ANOVA), correlation analysis, and regression analysis were performed using SPSS 25.0 statistical software. Results: The physical activity level differed significantly across sex (t = 14.37, p &lt; 0.001), grade (F=3.72, p &lt; 0.05), and monthly living expenses (F = 5.70, p &lt; 0.001). The mental toughness had significant differences across sex (t = 4.55, p &lt; 0.001), grade (F = 3.35, p &lt; 0.05), and monthly living expenses (F = 5.41, p &lt; 0.001). There were significant differences in mental toughness across different levels of physical activity intensity (F = 39.28, p &lt; 0.001), different length of physical activity (F = 33.35, p &lt; 0.001), different frequency of physical activity (F = 30.14, p &lt; 0.001), and different levels of physical activity (F = 91.55, p &lt; 0.001). Physical activity was significantly and positively correlated with mental toughness (r = 0.26, p &lt; 0.01). Conclusion: Male students exhibited significantly higher levels of physical activity than their female counterparts, and freshmen demonstrated greater physical activity than students in other grades. Additionally, the amount of physical activity among college students was influenced by their monthly living expenses. The mental toughness score of male students was notably higher than that of female students, with freshmen scoring significantly higher than students in other grades. In comparison to other levels of physical activity, engaging in a high quantity of exercise, high-intensity short-duration exercise, more than 60 minutes of activity time, and a daily activity frequency had the most pronounced impact on enhancing mental toughness. Moreover, there was a positive correlation between physical activity and mental toughness.

Association between the Number of Days/Week of Different Levels of Physical Activity and Chronic Pain in People of Different Races: A Mendelian Randomization Study.

Regular physical activity is beneficial for health, but the effect of the number of days/week of physical activity on chronic pain (CP) remains unclear, so we used a two-sample Mendelian randomization (MR) analysis to explore the relationship between the number of days/weeks of different levels of physical activity and chronic pain in people of different races. We obtained summary data from genome-wide association studies (GWASs) on the number of days/week of physical activity and multisite chronic pain in European, South Asian, East Asian, Middle Eastern, and African American populations. The single-nucleotide polymorphisms (SNPs) of the exposed data were visualized with a Manhattan plot via the R program. MR analysis was performed by the MR-Base platform. The results indicated that a higher number of days/week with ≥10 min of walking protects against CP in African American and Afro-Caribbean populations (inverse-variance weighting, IVW p < 0.05) but has little effect on people of different races (IVW p > 0.05). A higher number of days/week with ≥10 min of moderate physical activity increased the risk of CP in European and South Asia (IVW p < 0.05) but had little effect on people of different races (IVW p > 0.05). The number of days/week of ≥10 min of vigorous physical activity increased the risk of CP in Europeans (IVW p < 0.05) and protected against CP in African Americans and Afro-Caribbeans (IVW p < 0.05). A higher number of days/week of moderate and vigorous physical activity increased the risk of CP in Europeans; however, a higher number of days/week of walking and vigorous physical activity may protect against CP in African American and Afro-Caribbean individuals.

Effects of Different Kinds of Physical Activity on Vascular Function.

Regular exercise is one of the main non-pharmacological measures suggested by several guidelines to prevent and treat the development of hypertension and cardiovascular disease through its impact on the vascular system. Routine aerobic training exerts its beneficial effects by means of several mechanisms: decreasing the heart rate and arterial pressure as well as reducing the activation of the sympathetic system and inflammation process without ignoring the important role that it plays in the metabolic profile. Through all these actions, physical training counteracts the arterial stiffening and aging that underlie the development of future cardiovascular events. While the role of aerobic training is undoubted, the effects of resistance training or combined-training exercise on arterial distensibility are still questioned. Moreover, whether different levels of physical activity have a different impact on normotensive and hypertensive subjects is still debated.

The influence of accelerometer epoch length on physical activity output in adolescent athletes.

Epoch in accelerometer measurements is an important option that affects the results of physical activity (PA) analysis. Many studies have been conducted to investigate the effect of epoch on PA output in adolescents, but few have been performed on highly active youth athletes. We aimed to examine the differences in energy expenditure and time spent in different activity intensities by applying various epoch lengths in adolescent athletes. The participants of this study comprised 31 male athletes aged 12 to 13 in basketball, soccer, and taekwondo teams. Athletes wore a tri-axial accelerometer attached to the right hip for 6 to 7 consecutive days, including sleeping time. Subsequently, the recorded data from the accelerometer were downloaded using the ActiLife software and analyzed by varying the epoch to 1, 10, 30, and 60 sec. Daily average metabolic equivalents (METs) increased as the epoch increased (F=2.918, P=0.037), showing a significant difference between 1 and 60-sec epochs. As epoch length increased, sedentary (0-1.5 METs) (F=94.001, P=0.000) and high intensity (6 METs and higher) activity time (F=3.536, P=0.017) decreased, while low (1.5-3 METs) (F=173.949, P= 0.000), moderate (3-6 METs) (F=70.792, P=0.000), and moderate-to-vigorous activity (3 METs and higher intensity) (F=34.683, P=0.000) times increased. Comparing PA among adolescent athletes by varying epoch settings of accelerometers revealed differences in PA levels and time spent in different activity intensities. Future studies should consider the characteristic changes in the PA outputs according to the epoch length in very active adolescent athletes.
