Background and Aim: Many diseases cause skeletal muscle microvascular rarefaction (MR) and the quantitative determination of the effect size (ES) of exercise training on skeletal muscle capillary to fiber ratio (C/F) can be useful in refining exercise prescriptions for susceptible population. The aim of the present study was to determine the average ES of exercise training on skeletal muscle C/f in patients disposed to MR. Materials and Methods: A search for English articles was conducted in Web of Science, Scopus, and PubMed databases without limiting the year of publication until February 2023. Weighted mean difference (WMD) with 95% confidence intervals was calculated using random effect model. Correlation between variables was investigated using fixed effects model meta-regression.Results: A summary ES achieved as WMD=0.21 (95% CI: 0.17 to 0.26) from the results of 308 subjects, included in 22 exercise training interventions (p=0.014, I2=44.16). No correlations were observed in between the changes in C/F and the age of subjects included in each intervention based on action of the moment’s meta-regression model (r=-0.00, p=0.92, z=0.099). Among the exercise duration categories, interventions less than 8 weeks (n=3) had the least ES on C/F (WMD=0.18), while a WMD of 0.22 were determined for both of interventions with 8 weeks (n=7) and more than 8 weeks duration (n=12) categories (z=9.68, p=0.001). Moreover, interventions in HIIT and intensive aerobic exercise training category had greater ES (WMD=0.23) compared to MICT and aerobic exercise training (WMD= 020) interventions (z=9.73, p=0.001). =

Introduction: This study aims to explore the impact of aerobic exercise and green tea extract consumption on cardiac prognostic markers in men diagnosed with type 2 diabetes.Method: The study involved 32 male participants with type 2 diabetes, aged 50 ± 10.9 years, divided into four groups: 1) green tea (GT), 2) green tea combined with aerobic training (GT+AT), 3) placebo (PL), and 4) placebo combined with aerobic training (PL+AT). Over an 8-week period, the AT protocol was performed for 60 minutes at an intensity of 55-65% of maximum heart rate (MHR) on a treadmill. Green tea extract was consumed at a dosage of 800 mg daily. Serum levels of cardiac markers, including GDF-15 and NT-proBNP, were assessed through blood sampling before and after the intervention. Data were analyzed using ANOVA with repeated measures and Bonferroni's post hoc test.Results: The results indicated a significant decrease in serum levels of GDF-15 and NT-proBNP in the post-test compared to the pre-test in the GT, GT+AT, and PL+AT groups (P

Background. Galactin3 is known to be a novel inflammatory factor that increases with type 2 diabetes. Therefore, the aim of the present study was to investigate the effect of high intensity interval and moderate intensity continuous exercise on serum levels of Galectin3 in inactive obese men.Methods. Eight obese men (mean age: 25.75±2.37 years and BMI: 31.96±3.03 kg/m2) performed protocols of high intensity interval exercise (HIIE), moderate intensity continuous exercise (MICE) and control (C) on separate days with a week. The HIIE protocol included six bouts of 1-minute running with intensity of 85% VO2max and 4 min active rest periods with intensity of 50% VO2max and the MICE protocol included 30 minutes running on treadmill with intensity of 65% VO2max which was matched with the HIIE protocol. Serum Galectin3 levels were measured by ELISA in 3 stages of before exercise, immediately after exercise, and 24 h after exercise.Reults. Immediately after exercise, HIIE and MICE resulted in a significant increase in serum Galectin3 compared to the control group (p
