Exercise as an anti-inflammatory Therapy in Axial Spondyloarthritis Therapeutic Intervention (EXTASI) study: a randomized controlled trial

Abstract Objectives Axial SpA (axSpA) is a chronic inflammatory disease, yet despite known anti-inflammatory effects of exercise, the effect of exercise on inflammatory immune cell populations and associated inflammatory profiles in axSpA is unknown. This randomized controlled trial investigated the effect of 12 weeks of walking on symptom severity, cardiometabolic health, inflammatory biomarkers and immune cell populations. Methods Twenty people (60% male) living with axSpA who were on a stable dose of NSAIDs participated. Participants were randomly assigned to control or exercise (30 min of walking five times per week). Participants were invited back every 4 weeks for assessment. Results There was a 0% dropout rate and no adverse events in the exercise group, showing walking exercise was well tolerated. Home-based walking for 12 weeks lowered the proportion of pro-inflammatory monocytes, whereas they increased in the control group. Changes were associated with lower IL-6 and CRP concentrations, lower spinal pain and lower systolic blood pressure in the exercise group, whereas these markers increased in the control group. Reductions in IL-6 and pro-inflammatory monocytes with exercise were independent of lower body fat percentage. Conclusions Supplementing NSAID therapy with walking exercise can improve inflammatory immune profiles in people with axSpA, coinciding with reductions in spinal pain. Importantly, the exercise was well tolerated, suggesting walking exercise can be used as an adjuvant anti-inflammatory therapy for NSAID treatments. This should now be explored in people living with axSpA who have had high enough disease activity to necessitate the prescription of biologic or synthetic DMARD treatments.

Impact of age on the prevalence of poor-quality dietary variety, associated lifestyle factors, and body composition profile (low body muscle mass and high body fat mass) in older people residing in Colombo district, Sri Lanka

AimsTo assess the impact of age on the prevalence of poor-quality dietary variety, associated lifestyle factors, and body composition profile (low body muscle mass and high-fat mass) in older Sri Lankans. MethodsIn this population-based cross-sectional study, older people of 60 years or above were selected using a multistage cluster sampling technique probability proportionate to the size. They were classified into 3 groups; 60–64, 65–69 and > 70-years. The poor-quality dietary variety was defined based on food variety, dietary diversity and dietary serving scores assessed using 24-h dietary recall. Body composition was measured using bio-electrical impedance. The impact of age on determinants of poor-quality dietary variety and being at risk of low muscle mass and high-fat mass were assessed by using multivariable logistic regression models. ResultsEight hundred older participants with a mean (SD) 68.1(5.8) years were included. There were 28.4%(n = 227), 36.2%(n = 290) and 35.4%(n = 283) in the 60–64, 65–69 and ≥ 70-year age groups, respectively. The prevalence of poor-quality dietary variety was similar across age groups. The urban living environment, and getting nutritional advice from the GP/hospital were found to have a significant negative association only in the 60–64 age group. A poor-quality dietary variety was significantly associated with no education or up to the primary level in the 65–69 age group and having diabetes or hypertension in the ≥70-year group. Odds of low muscle mass and high-fat mass were 2.43(1.46–4.03) and 2.17(1.30–3.63) respectively among the≥70-year age group compared to the 60-64-year group, after controlling for confounders. ConclusionsThe prevalence of poor-quality dietary variety was similarly high in all age groups. Increasing age was associated with higher odds of low body muscle and high body fat mass despite similar dietary variety, indicating the need for special dietary attention.

Body composition is related to cognitive function among young adults in Ghana

BackgroundA growing body of evidence suggests that obesity can affect cognitive function. However, it is unclear whether this effect is independent of obesity-related comorbidities. This study thus sought to determine the association between body composition and cognitive function of young adults in Ghana with less predisposition to obesity-related comorbidities.MethodsA cross-sectional study design was employed, involving 381 participants recruited by simple random sampling. After consenting, participants completed questionnaires that assessed sociodemographic characteristics, along with assessments for anthropometric measures and cognitive function. Analyses for associations were conducted by either Pearson’s correlation test or chi-Square test of independence.ResultsOver half (60%) of participants were females and 69.6% were in the first year with a mean age of 20.18 ± 2.52 years. Based on Pearson’s correlation test, no significant association was found between Body Mass Index (BMI) and Waist to Hip Ratio (WHR), and Trail Making Test-A and B (TMT-A and TMT-B). Nonetheless, a chi-square test showed a significant association, between BMI and TMT-A (p = 0.01), and WHR and both TMT-A (p = 0.001) and TMT-B (p = 0.02). Weak direct correlations were found between body fat percentage and TMT-A (r = 0.120, p = 0.019) and TMT-B (r = 0.133, p = 0.009). Further, a weak inverse correlation was found between muscle mass and TMT-A (r = − 0.141, p = 0.006) and TMT-B (r = − 0.144, p = 0.005).ConclusionHigh body fat, low muscle mass and body fat distribution may have a significant association with cognitive functions and must be considered in obesity interventions. This study provided more insight on the association between BMI and cognitive function and would be helpful in designing new weight management interventions or modifying existing interventions to consider the influence of obesity on cognitive function.

Impaired mitochondrial respiration in upper compared to lower body differentiated human adipocytes and adipose tissue.

Abdominal obesity is associated with increased cardiometabolic disease risk, while lower body fat seems to confer protection against obesity-related complications. The functional differences between upper and lower body adipose tissue (AT) remain poorly understood. We aimed to examine whether mitochondrial respiration is impaired in abdominal as compared to femoral differentiated human multipotent adipose-derived stem cells (hMADS; primary outcome) and AT in postmenopausal women. In this cross-sectional study, 23 postmenopausal women with normal weight or obesity were recruited at the University of Birmingham/Queen Elizabeth Hospital Birmingham (Birmingham, UK). We collected abdominal and femoral subcutaneous AT biopsies to determine mitochondrial oxygen consumption rates in differentiated abdominal and femoral hMADS. Furthermore, we assessed OXPHOS protein expression and mtDNA content in abdominal and femoral AT as well as hMADS. Finally, we explored in vivo fractional oxygen extraction and carbon dioxide release across abdominal and femoral subcutaneous AT in a subgroup of the same individuals with normal weight or obesity. We found lower basal and maximal uncoupled mitochondrial oxygen consumption rates in abdominal compared to femoral hMADS. In line, in vivo fractional oxygen extraction and carbon dioxide release were lower across abdominal than femoral AT. OXPHOS protein expression and mtDNA content did not significantly differ between abdominal and femoral differentiated hMADS and AT. The present findings demonstrate that in vitro mitochondrial respiration and in vivo oxygen fractional extraction are lower in upper compared to lower body differentiated hMADS and AT, respectively, in postmenopausal women.

Body morphology and handgrip strength parameters of the female canoe slalom paddlers.

Introduction: Canoe slalom is a physically very demanding discipline, in which body constitution, body composition, and relative strength are significant factors in high performance. Although anthropometric and strength parameters are relatively well-studied in male athletes, there is a lack of evidence for any conclusions in women. Therefore, the objective of this study was to determine the morphology and upper-limb strength parameters of female canoe slalom paddlers and identify whether morphological differences exist between performance groups. Methods: Altogether, 63 female competitors of the 2023 ICF Canoe Slalom World Cup (n = 29) and 2023 ICF Canoe Slalom World Ranking Competition (n = 34) in Prague (Czech Republic) were examined with a battery of anthropometric tests, segmental bioimpedance analysis, and handgrip strength test. The athletes were divided into groups according to age and performance: elite athletes belonging to the world top 10 according to the ICF World Ranking (WORLD, n = 7), international-level athletes competing during the World Cup (ELITE, n = 22), international-level junior athletes competing in the World Ranking Race (JUNIOR, n = 17), and other lower performance-level athletes competing in the World Ranking Race (REST, n = 17). Results: Female slalom paddlers are, in general, of average body height (∼165cm), lower body mass (∼60kg), BMI (∼22kg/m2), and body fat (∼20%) and without exceptional anthropometric dimensions and proportions. However, differences were detected when performance was factored in. Female paddlers belonging to the world TOP 10 have the largest circumferences of arms and forearms, and their somatotype is more mesomorphic, with a lower proportion of total body fat and a higher proportion of muscle mass. In addition, the WORLD group differs significantly in upper-limb strength. Discussion: The results shows the significance of muscular strength and power for canoe slalom athletes and the importance of well-developed musculature in operating the boat in the unstable environment. Being a successful female canoe slalom athlete requires a well-developed musculature, maximizing strength capabilities while maintaining a low body weight through limited hypertrophy of the lower limbs and a low level of body fat.

Modulation of Performance, Plasma Constituents, Small Intestinal Morphology, and Cecum Microbiota in Growing Geese by Dietary Citric Acid Supplementation.

To investigate the efficiency and optimum inclusion level of CA in growing geese diets on performance, plasma constituents, and intestinal health, 240 healthy female geese at the age of 28d were randomly allotted six treatment diets incorporated with 0, 0.8, 1.6, 2.4, 3.2, and 4% CA. Each treatment group consisted of five replicates and eight birds per replicate. The findings demonstrated that 3.2% CA supplementation resulted in improved growth performance (ADG, ADFI, and FBW) (p = 0.001), and geese who received CA also showed lower body fat contents (p < 0.05) than the control group. Moreover, geese from the 2.4% and 3.2% CA group had the highest plasma glutathione peroxidase and insulin-like growth factor 1 levels compared to the other groups (p < 0.05). A microbial diversity analysis of the cecum conducted by 16S rDNA sequencing revealed that 3.2% CA supplementation showed a significantly higher abundance of beneficial bacteria (Muribaculaceae, CHKCI001, Erysipelotricha-ceae_UCG_003, and UCG_009) (p < 0.05) and a lower abundance of harmful bacteria (Atopobiaceae, Streptococcus, Acinetobacter, Pseudomonas, and Alistipes) (p < 0.10). Collectively, our results revealed that dietary supplementation with 3.2% CA had several benefits on the performance and physiological health of growing geese by promoting nutrients metabolism, improving antioxidant capacity, and modulating cecum microbiota.

Body composition, lifestyle, and depression: a prospective study in the UK biobank.

Obesity has been related to depression and adhering healthy lifestyle was beneficial to lower the risk of depression; however, little is known about the relationship between body composition and fat distribution with depression risk and the influence of body composition and fat distribution on the association of lifestyle and depression. Therefore, we aimed to investigate whether body composition and fat distribution were associated with the adverse events of depression and the relationship between lifestyle and depression. We included 330,131 participants without depression at baseline in the UK Biobank (mean age, 56.9 years; 53.83% females). The assessment of depression was sourced from health outcomes across self-report, primary care, hospital inpatient data, and death data. Body composition was determined by bioelectrical impedance. Seven lifestyles (no current smoking, moderate alcohol consumption, regular physical activity, healthy diet, less sedentary behavior, healthy sleep pattern, and appropriate social connection) were used to generate a lifestyle score. During a median of 11.7 years of follow-up, 7576 incident depression occurred. All the body composition measures were positively associated with depression risk, with the Hazard ratios (HR) for the uppermost tertile (T3) versus the lowest tertile (T1) ranging from 1.26 (95% CI: 1.15-1.39) for trunk fat-free mass (TFFM) to 1.78 (1.62-1.97) for leg fat percentage (LFP). In addition, we found significant interactions between fat mass-related indices, especially leg fat mass (LFM) (p = 1.65 × 10-9), and lifestyle score on the risk of depression, for which the beneficial associations of a healthy lifestyle with the risk of depression were more evident among participants with low body fat measurement. High levels of body composition measures were associated with an increased depression risk. Adverse body composition measures may weaken the link between a healthy lifestyle and a reduced risk of depression.

The role of long-term combination training in reducing and maintaining of body fat in obese young adult women

Reducing body weight and body fat is the primary goal for overcoming obesity. Lifestyle modifications with a non-pharmacological approach based on programmed physical exercise are recommended for increasing energy expenditure and reducing body weight and body fat. This study aims to analyze different types of exercise in reducing and maintaining body fat in obese young adult women. This study was a randomized controlled trial (RCT) with a true experimental design. A group of 28 sedentary overweight women were enlisted and provided with aerobic, strength, and mixed exercise regimens. Aerobic, resistance, and combined training programs were conducted with an intensity of 60-70% HRmax for aerobic, and 60-70% 1-RM for resistance. These sessions were performed 3x/week for 4 weeks. Measurement of body fat before-intervention and 24 hours after-intervention for 4 weeks using Seca mBCA 554. The one-way ANOVA test was utilized for statistical analysis, with a significance level of 5%. The findings demonstrated a significant reduction in body fat through all three forms of exercise, evident in the decrease in changes in body mass index, body weight, fat mass, and free fat mass (p ≤ 0.05). Additionally, all three exercise modalities led to a significant increase in changes in skeletal muscle mass in comparison to the control group (p ≤ 0.05). Our study results concluded that the combination type of exercise performed 3x/week for 4 weeks was more beneficial in lowering body fat and increasing muscle mass compared to aerobic exercise and resistance type exercise in obese young adult women.

Low Body Fat Percentage and Menstrual Cycle Disorders in Female Elite Adolescent Dancers.

Introduction: The menstrual cycle is an important indicator of health in female athletes. Female elite adolescent dancers are expected to control their weight while also training intensely, which can lead to menstrual disorders. This study aimed to investigate the relationship between body composition and menstrual status in female elite adolescent dancers. Methods: In total, 131 female elite adolescent dancers (age: 15.9 ± 1.5 years) were enrolled in this study. We measured the height, weight, and body fat percentage (BFP) for each participant and calculated their body mass index (BMI). We gathered information on individual menstruation patterns and the participants' menstrual cycles over the previous year using recall methods. We then compared the differences between dancers with menstrual cycle disorders and those without. Primary amenorrhea was defined as menarche occurring after the age of 15, while secondary amenorrhe was defined as experiencing fewer than 5 or no menstrual periods for at least 3 of the previous 12 months. We conducted a reliability test using the same questionnaire 2 weeks later. Statistical significance was defined as P < .05, and we calculated the effect sizes (d) and 95% confidence intervals (95% CI). Results: The average BMI and BFP were 22.6 ± 3.0% and 19.4 ± 2.2 kg/m2, respectively. Low BFP and low BMI were observed in 51 (38.6%) and 47 (35.6%) participants, respectively. Primary amenorrhea in 3 participants (2.3%) and 29 (22.1%) reported experiencing secondary amenorrhea; they had lower BFP than the dancers who did not experience amenorrhea (P = .041, 95% CI, -2.51 to -0.05). Conclusion: Female elite adolescent dancers in China may have lower BFP and menstrual problems. Given that lower BFP may contribute to the occurrence of menstruation disorders, it is essential to pay an attention to both BFP and the menstruation status in female elite adolescent dancers.

Oreo Cookie Treatment Lowers LDL Cholesterol More Than High-Intensity Statin therapy in a Lean Mass Hyper-Responder on a Ketogenic Diet: A Curious Crossover Experiment.

Recent research has identified a unique population of 'Lean Mass Hyper-Responders' (LMHR) who exhibit increases in LDL cholesterol (LDL-C) in response to carbohydrate-restricted diets to levels ≥ 200 mg/dL, in association with HDL cholesterol ≥ 80 mg/dL and triglycerides ≤ 70 mg/dL. This triad of markers occurs primarily in lean metabolically healthy subjects, with the magnitude of increase in LDL-C inversely associated with body mass index. The lipid energy model has been proposed as one explanation for LMHR phenotype and posits that there is increased export and subsequent turnover of VLDL to LDL particles to meet systemic energy needs in the setting of hepatic glycogen depletion and low body fat. This single subject crossover experiment aimed to test the hypothesis that adding carbohydrates, in the form of Oreo cookies, to an LMHR subject on a ketogenic diet would reduce LDL-C levels by a similar, or greater, magnitude than high-intensity statin therapy. The study was designed as follows: after a 2-week run-in period on a standardized ketogenic diet, study arm 1 consisted of supplementation with 12 regular Oreo cookies, providing 100 g/d of additional carbohydrates for 16 days. Throughout this arm, ketosis was monitored and maintained at levels similar to the subject's standard ketogenic diet using supplemental exogenous d-β-hydroxybutyrate supplementation four times daily. Following the discontinuation of Oreo supplementation, the subject maintained a stable ketogenic diet for 3 months and documented a return to baseline weight and hypercholesterolemic status. During study arm 2, the subject received rosuvastatin 20 mg daily for 6 weeks. Lipid panels were drawn water-only fasted and weekly throughout the study. Baseline LDL-C was 384 mg/dL and reduced to 111 mg/dL (71% reduction) after Oreo supplementation. Following the washout period, LDL-C returned to 421 mg/dL, and was reduced to a nadir of 284 mg/dL with 20 mg rosuvastatin therapy (32.5% reduction). In conclusion, in this case study experiment, short-term Oreo supplementation lowered LDL-C more than 6 weeks of high-intensity statin therapy in an LMHR subject on a ketogenic diet. This dramatic metabolic demonstration, consistent with the lipid energy model, should provoke further research and not be seen as health advice.

Relationships between physical behaviour phenotypes of mothers in pregnancy and their offspring with child body composition.

The aim of this study was to identify physical behaviour phenotypes in mothers in the first trimester and in their offspring at 24 months of age. The secondary aim was to examine relationships between mother and child behaviours with child body composition at age 24 months. Longitudinal secondary analysis of the Glowing cohort collected between 1 February 2011 and 22 August 2017 in Little Rock, Arkansas. Behaviours were measured using ankle-worn accelerometers in mothers during the first trimester and offspring at 24 months of age, including total activity, sleep, sedentary time and a novel variable of daily variation, patternicity. Child body fat was measured using quantitative nuclear magnetic resonance. Three phenotypes were identified for mothers and children (n = 159 complete dyads). There were no relationships between mother and child phenotypes, but higher maternal patternicity was associated with higher child patternicity (0.2, 95% CI 0.1, 0.3, p = 0.001). There were no associations between mother or child phenotypes with child body composition, however higher child activity was associated with lower body fat (-0.01, 95% CI: -0.02, -0.001, p = 0.031). Limited associations were found between mothers' pregnancy physical behaviours with child behaviours or child body composition at 24 months of age. Factors such as child diet or current parental physical activity may be better predictors of early childhood outcomes.

Fructose-induced FGF21 secretion does not activate brown adipose tissue in Japanese young men: randomized cross-over and randomized controlled trials

BackgroundHuman brown adipose tissue (BAT) activity is associated with lower body fatness and favorable glucose metabolism. Previous studies reported that oral fructose loading induces postprandial fibroblast growth factor 21 (FGF21) secretion. FGF21 is a known inducer of adipose tissue thermogenesis; however, the effects of diet-induced FGF21 secretion on BAT thermogenesis remain to be elucidated.MethodsThe effects of both single load and daily consumption of fructose on BAT activity were examined using a randomized cross-over trial and a 2-week randomized controlled trial (RCT), respectively. In the cross-over trial, 15 young men consumed a single dose of fructose solution or water and then consumed the other on a subsequent day. The RCT enrolled 22 young men, and the participants were allocated to a group that consumed fructose and a group that consumed water daily for 2 weeks. BAT activity was analyzed using thermography with cold exposure. Plasma FGF21 level was determined by enzyme-linked immunosorbent assay.ResultsIn the cross-over single-load trial, plasma FGF21 levels were significantly increased at 2 h after oral fructose load (p < 0.01); however, there was no significant difference in BAT activity between the fructose load and drinking water. The 2-week RCT revealed that both plasma FGF21 levels and BAT activity were not significantly increased by daily fructose consumption compared to water. Correlation analyses revealed that BAT activity at the baseline and the final measurements were strongly and positively associated with the RCT (r = 0.869, p < 0.001). Changes in BAT activity were significantly and negatively correlated with changes in plasma glucose levels during the 2-week intervention (r = − 0.497, p = 0.022).ConclusionsOral fructose load induces a temporary increase in circulating FGF21 levels; however, this does not activate BAT thermogenesis in healthy young men. Further studies are needed to elucidate the effect of endogenous FGF21 on physiological function.Trial registrationThis study is registered with the University Hospital Medical Information Network in Japan (number 000051761, registered 1 August 2023, retrospectively registered, https://center6.umin.ac.jp/cgi-open-bin/ctr/ctr_view.cgi?recptno=R000052680).

Systemic Sirtuin 1 as a Potential Target to Mediate Interactions Between Body Fat and Testosterone Concentration in Master Athletes.

Evidence indicates that master athletes have higher concentration of Sirtuin 1 (Sirt1), lower body fat (BF), and greater activity of the hypothalamic-pituitary-gonadal axis in comparison to untrained peers. However, no published data have demonstrated possible mediation effect of Sirt1 in the interaction of BF and testosterone in this population. Therefore, this study compared and verified possible associations between Sirt1, BF, fat mass index (FMI), testosterone, luteinizing hormone (LH), and testosterone/luteinizing hormone (T/LH) ratio in middle-aged master athletes (n = 54; 51.22 ± 7.76years) and control middle-aged peers (n = 21; 47.76 ± 8.47years). Venous blood was collected for testosterone, LH, and Sirt1. BF was assessed through skinfold protocol. Although LH concentration did not differ between groups, master athletes presented higher concentration of Sirt1, testosterone, and T/LH ratio, and lower BF and FMI in relation to age-matched nonathletes. Moreover, Sirt1 correlated positively with testosterone and T/LH ratio, negatively with BF, and was not significantly correlated with LH (mediation analysis revealed the effect of BF on testosterone is mediated by Sirt1 and vice versa; R2 = .1776; p = .032). In conclusion, master athletes have higher testosterone, T/LH ratio, and Sirt1, and lower BF and FMI in relation to untrained peers. Furthermore, Sirt1 was negatively associated with BF and positively associated with testosterone and T/LH ratio. These findings suggest that increased circulating Sirt1, possibly due to the master athlete's training regimens and lifestyle, exhibits a potential mediation effect on the interaction between endocrine function and body composition.

Study of peak expiratory flow rate in male and female young adults with respect to their weight status

Background: Young adults are more attracted toward fast food, alcohol, and sedentary lifestyles. Previous study shows that peak expiratory flow rate (PEFR) correlates better with height in males and weight in females. Body mass index (BMI) is one of the main factor that affect PEFR values. PEFR, a pulmonary function test is routinely used to confirm the diagnosis of the respiratory disease. Aim and Objectives: This study was conducted to evaluate PEFR values in male and female young adults in underweight, normal, overweight, and obese categories of weight status. Materials and Methods: The study was conducted in four groups. 40 participants in each group, includes males (20) and female (20) young adults. The groups were divided according to BMI values, underweight (&lt;18.5), normal (18.5–24.9), overweight (25–29.9), and obese (&gt;30). Data were taken and calculated 2 h post lunch after relaxing for 15 min in the afternoon. In the sitting position, at the same time of the day, PEFR values were measured using Wright’s Peak Flow Meter. Results: We found significantly high PEFR values in males as compare to females in the category of underweight (&lt;0.01), normal (&lt;0.05) and overweight (&lt;0.05). The study also shows positive correlation between BMI and PEFR in underweight male and females, normal males, overweight females, and obese females, which is statistically non-significant, except in obese males. Conclusion: We concluded that male have high PEFR values than female as there are differences in their body build-up and low PEFR values in underweight and obese young adults as they have low body fat and reduced expansion of lungs, respectively.

Impact of cycling and walking on adiposity and healthcare costs among adults: longitudinal study.

Leisure-time physical activity seems relevant to prevent the development of chronic diseases and obesity. However, not much is known about the economic burden of these healthy behaviors, mainly in longitudinal designs. This study aimed to analyze the impact of walking and cycling on leisure-time on adiposity and healthcare costs among adults. This longitudinal study was conducted at a medium-size Brazilian city and included 198 participants with no missing data attended in the Brazilian Unified National Health System. Cycling and walking were assessed by a questionnaire with a face-to-face interview at four time-points (baseline, 6-month, 12-month, and 18-month). Healthcare costs were assessed using medical records. Adiposity markers included waist circumference and body fatness. Over the follow-up period, participants who were more engaged in cycling presented lower body fatness (p-value = 0.028) and healthcare costs (p-value = 0.038). However, in the multivariate model, the impact of cycling on costs was not significant (p-value = 0.507) due to the impact of number of chronic diseases (p-value = 0.001). Cycling on leisure-time is inversely related to adiposity in adults, whereas its role on preventing chronic diseases seems the main pathway linking it to cost mitigation.

Body weight circuit: does it affect fat percentage, muscle and cardiovascular fitness in adult women in singcronous?

Purpose. The study’s goal was to determine the relationship between fat percentage and muscle and cardiovascular fitness, as well as the effect of the circuit body weight training method on muscle and cardiovascular fitness. Methods. Fitness requires effective and efficient methods, one of which is the circuit body weight training method. Some women’s perspectives on weight training have not been prioritized; there is still a lack of understanding on the regulation of exercise doses; and inconsistent studies of the relationship between fat percentage and physical fitness need seeking out the most recent data. A sample of 20 adult women aged 30-50 years was employed in this correlational and experimental study. The instruments used are a hand grip dynamometer, a leg and hand dynamometer, a rockpot, and an Omron body fat monitor. Techniques for collecting data from tests and measurements. The Spearman Rho test was used to analyze the data, along with Wilcoxon which assisted by SPSS 23. Results. The correlation results revealed a significant relationship between body fat percentage and hand, leg, back, and cardiovascular fitness, with a sig value of 0.05. The comparison revealed significant differences in pretest and posttest percentage of fat, back muscle fitness, limbs, and cardiovascular with a sig 0.05, but not in hand squeeze. It was determined that as the percentage of fat in the body decreased, fitness increased and vice versa. Circuit body weight training boosts cardiovascular fitness, lowers body fat percentage, and improves muscle fitness. Conclusions. Even though the power of hand squeezing is insignificant, it produces positive results. It is hoped that this study will provide information and a better understanding of weight training. The research is limited to adult women, the sample size is small, and there is no control group. This study can be improved through additional research.

Anthropometric and Somatotype Characteristics of Top Elite Turkish National Jumpers

Introduction: This study aims to comprehensively investigate the anthropometric and somatotype characteristics of elite Turkish national jumpers specializing in high jump, long jump, pole vault, and triple jump disciplines. Recognizing the fundamental significance of body composition and somatotype in athletic performance, the research delves into the intricate interplay between these attributes, and competitive accomplishments. Methods: Leveraging a cohort of 13 national athletes, comprising six females and seven males, the methodology involves the application of standardized anthropometric measurements and the Heath-Carter method for somatotype assessment. Results: The outcomes illuminate distinct profiles, featuring lower body fat percentages in Turkish elite jumpers when compared to existing studies. Additionally, the study reveals gender-specific variations in muscle mass and discerns unique somatotype patterns within the cohort. Significantly, somatotype scores align with global trends observed in elite high jump athletes, emphasizing universal patterns among top-level performers. Comparative analyses with international studies further underscore commonalities in somatotype components among elite athletes. Furthermore, it was discerned that the top jumpers in both genders exhibited lower body height and body weight in comparison to their elite high-jumping counterparts. This research contributes to a refined understanding of the morphological intricacies associated with proficiency in these disciplines, offering valuable insights for optimizing training regimens. Conclusion: In summary, the study underscores the pivotal role played by anthropometric and somatotype characteristics in shaping the success of top elite Turkish national jumpers.

Demographic Insights Into College-Going Students in India: A Morphological Analysis

Introduction: In the context of India's diverse culture and changing education system, it is crucial to understand the morphological characteristics of college students, especially with the government actively supporting sports through initiatives like the "Khelo India" program to aid young athletes. The purpose of the study was to investigate the morphological characteristics of college-level athletes and non-athletes in India. Methods: 287 college students have been randomly selected to acquire a comprehensive set of demographic and anthropometric data. Results: The study revealed significant differences in body mass index (p=0.004), endomorphy (p=0.001), ectomorphy (p=0.02), and body fat percentage (p=0.001). However, no significant difference in mesomorphy (p=0.09) was identified, and only minimal differences in fat-free mass (p=0.57) were observed. College-level athletes exhibit an ectomorphic-mesomorphic physique (2.9-3.9-3.0), characterized by a distinct blend of muscularity and leanness. Non-athletes are mesomorphic-endomorphs (5.0-4.3-2.4), exhibiting higher body fat content and muscularity. Athletes had a significantly lower body fat percentage, highlighting the positive influence of sports training and regular physical exercise on reducing adiposity. The analysis of percentile rankings provides comprehensive insights into the distribution of anthropometric metrics among athletes and non-athletes, assisting in customizing training regimens, identifying areas for potential improvement, and enhancing a comprehensive assessment of individuals' physical characteristics. Conclusion: The study sheds light on the crucial role of morphological traits in discerning differences between college-level athletes and non-athletes within the broader context of the "Fit India Movement." The study will help design an effective training module to improve the overall health of college students.

Effects of Supplementation of Murici (Byrsonima crassifolia) and Taperebá (Spondias mombin) Pulp Extracts on Food Intake, Body Parameters, and Oxidative Stress Markers in Healthy Rats.

This study evaluates the effects of supplementation of murici (Byrsonima crassifolia) and taperebá (Spondias mombin) pulp extracts on dietary intake, body composition, biochemical parameters, and markers of oxidative stress. Two experiments were conducted with a total of 80 healthy male Wistar rats and a 30-day supplementation. In the first experiment, animals were divided into control (C) group, murici group 50 mg/(kg⸱day) (50Mu), murici group 100 mg/(kg⸱day) (100Mu), and murici group 200 mg/(kg⸱day) (200Mu). In the second experiment, animals were divided into C group, taperebá group 50 mg/(kg⸱day) (50Tap), taperebá group 100 mg/(kg⸱day) (100Tap), and taperebá group 200 mg/(kg⸱day) (200Tap). Results showed lower feed intake in 50Mu, 100Mu, and 100Tap groups (13%, 12%, and 10%, respectively, P < .05) and lower body fat in 200Mu, 100Tap, and 200Tap groups (16.0%, 29.1%, and 27.1%, respectively, P < .05). Only the 100Tap group showed reduced adipose tissue content (30.4%; P < .05). Increased plasma antioxidant capacity was observed at all doses for both fruits. Taperebá supplementation reduced ferrous oxidation-xylenol orange levels (50Tap: 8.4%, 100Tap: 16.1%, 200Tap: 24.3%; P < .05) and increased thiol levels (50Tap: 39%, 100Tap: 31%; P < .05). Serum thiobarbituric acid reactive substances levels were reduced in all groups receiving taperebá (50Tap: 77.7%, 100Tap: 73.1%, 200Tap: 73.8%; P < .05) and murici (50Mu: 44.5%, 100Mu: 34%, 200Mu: 43%; P < .05). Therefore, it is suggested that the inclusion of these fruits in the diet can contribute to health maintenance and disease prevention, through their effects on controlling food intake, improving body composition, and in combating oxidative stress.

The effect of cardio and tabata training methods in reducing body fat and increasing maximum aerobic capacity in obese students

This study aimed to determine the effect of cardio and tabata training on reducing body fat and increasing aerobic capacity. This research is an experimental research with a pre and post-control group design. The research sample was split into three groups, each with 9 participants: control group (K1), cardio group (K2), and Tabata group (K3), group division was carried out randomly on research subjects. K1 without any exercise, whereas K2 (cardio) is running and skipping at an intensity of 55% and 70% of one's maximum heart rate. K3 (Tabata) performs burpees and jogging with a 90% – 95% HR maximum intensity. A skinfold calliper was used to quantify body fat, and a 12-minute Cooper test was used to gauge aerobic capacity. The Manova test was employed for data analysis, and a significance threshold 0.05 was used. The result of this study is that K3 had significantly less body fat than K1 and K2, and K2 had significantly less body fat than K1 (p 0.05). Comparing K3 and K2 to K1, aerobic capacity was substantially improved (p 0.05). In conclusion, six weeks of cardio and Tabata training impacted lowering body fat and raising maximum aerobic capacity.
