Abstract
Background and objective: Type 2 diabetes (T2D) is a metabolic disease that leads to increased levels of lipids, therefore the present study aimed to investigate the effect of eight weeks of aerobic training(AT) with silymarin (S)consumption on lipid profile in men with type 2 diabetes.
Material and Methods: 60 middle-aged male volunteers were randomly divided into 4 groups, including: (1) control(C) + placebo, (2) AT + placebo, (3) S consumption and (4) AT+S consumption. The AT groups performed for eight weeks, three sessions per week and 20-45 minutes per session at an intensity of 60 to 85% of the reserve heart rate, and the S groups of consumed 140 mg / kg of S daily (in two meals). Serum levels of Low Density Lipoprotein (LDL), High Density Lipoprotein (HDL), Cholesterol (CHO), and Triglyceride (TG) were measured before and after the test. Data were analyzed using one-way ANOVA and Bonferroni’s test, and P value less than 0.05 was considered significant.
Results: AT reduced serum levels of LDL, CHO, TG and increased HDL in men with T2D(P ≥ 0.05). Consumption of S reduced LDL, CHO, TG and increased HDL in men with T2D(P ≥ 0.05). AT and S consumption reduced LDL, CHO, TG and increased HDL; also, decrease in LDL, CHO, TG and increase in HDL in the AT and S consumption group was more favorable than the effect of S alone (P ≥ 0.05).
Conclusion: It seems that AT and S consumption simultaneously have interactive effects on reducing LDL, CHO, TG and increasing HDL in men with T2D.

Abstract
Background and objective: Aging and menopause are associated with decreased antioxidant function, however, the role of exercise and estrogen consumption in the health of these people has been shown. The aim of the present study was to investigate the interactive effect of aerobic training (AT) and estrogen (Es) on serum levels of catalase (Cat) and glutathione peroxidase (Gpx) enzymes in ovariectomized rats.
Material and Methods: In this experimental study, 45 ovariectomized rats were randomly divided into 5 groups of 9 rats, including (1) control (C), (2) estrogen solvent (sesame oil) (Sh), (3) AT, (4), Es,and (5) AT+Es. Rats in groups 3 and 5 were trained for eight weeks and three sessions, and groups 4 and 5 randomly received 30 micrograms of estradiol valerate daily for eight weeks. Data analysis was analyzed using one-way analysis of variance and Tukey’s post hoc test at the significance level of 0.05.
Results: Cat levels in the AT (P= 0.006), Es (P= 0.005) and AT + Es (P = 0.001) groups were significantly higher than the control group. Cat levels in the AT + Es group were also significantly higher than in the Es group (P = 0.01). Gpx levels in the AT (P = 0.001), S (P = 0.001) and AT + Es (p = 0.001) groups were significantly higher than the control group, while in the S (P = 0.001) and AT + Es (P = 0.001) groups, they were significantly higher than the AT group.
Conclusion: It seems that aerobic training combined with estrogen consumption synergistically improves the function of the antioxidant system in ovariectomized rats. However, it seems that the signaling pathway of interventions requires further study.

Abstract
Background and Objective: Although the efficacy of selected training and antioxidant herbs in the treatment of diabetes mellitus has been determined, the interactive effect of selected training and aqueous extract of barberry on insulin resistance and risk factors of type2 diabetes mellitus is not well understood. The aim of the present study was to investigate the effect of aqueous extract of barberry and selected training on some blood factors in men with type2 diabetes.
Material and Methods: In this study, 48 middle-aged men an age range of 40-50 years with type2 diabetes participated in the study. The participants were randomly divided into four groups of 12 subjects, including(1)control, (2)aqueous extract of barberry consumption, (3)aerobic training, and (4)aerobic training+ barberry consumption, based on insulin resistance index. The participants in the aqueous extract of barberry consumption group received200 ml of barberry juice daily for8 weeks and the training and training+ barberry consumption groups performed the training protocol designed in the study for 8 weeks, while the control group did not receive any intervention.
Results: After 8 weeks of exercise training and consumption of aqueous extract of barberry, insulin resistance index, fasting insulin level, fasting blood glucose level, triglyceride level, low density lipoprotein (LDL)and total cholesterol were significantly decreased compared to the control group and high density lipoprotein (HDL)had a significant increase; on the other hand, regarding the intergroup changes, only the levels of LDL and CHO were significant compared to the aqueous extract of barberry consumption and aerobic training.
Conclusion: In general, aqueous extract of barberry consumption and regular exercise training seems to be effective in improving insulin resistance index and blood lipids levels in type2 diabetic patients.

Abstract
Background: Obesity carries great risks related to health, such as the development and progression of chronic inflammation and obvious metabolic disorders. This study aimed to examine the effect of eight weeks of moderate-intensity resistance training with garlic supplementation on the lipid profile in overweight women.
Methods: The present research was a semi-experimental study and the participants were 60 overweight women from Gachsaran City with (body mass index: 28/45±6/72) who were randomly divided into four groups (n = 15): supplemental exercise, placebo exercise, garlic supplemental, and placebo. Two training groups performed moderate-intensity resistance training for eight weeks and three sessions per week. One day before the start of training and 48 hours after the last training session, blood samples were collected to measure total cholesterol (TC), triglyceride (TG), LDL-C, and HDL-C variables. Data were analyzed by one-way ANOVA and LSD post-hoc test.
Results: Findings showed that there is a significant decrease in the serum levels of TC, TG, and LDL-C and a significant increase in HDL-C (P<0.05) serum levels in three groups of supplemental exercise, placebo exercise, and garlic supplemental compared to the placebo group.
Conclusion: Moderate-intensity resistance training with and without consuming garlic improves overweight women's lipid profile, and when exercise is accompanied by consuming garlic, the amount of these changes and improving the lipid profile is greater.

Abstract
Background: The use of complementary medicine in healthcare is increasing rapidly. Therefore, the aim of the current study was to investigate the effect of eight weeks of high-intensity interval training and moderate-intensity continuous training with quercetin supplementation on the gene expression of FOXO1 and ATG5 in the liver of diabetic obese rats.
Methods: In this experimental study, 42 male Wistar rats were considered research samples at eight weeks. Rats were induced with diabetes after eight weeks of a high-fat diet and familiarization with a laboratory environment and treadmill. Rats were divided into seven groups, and six rats were placed in each group (n=6): healthy control group, diabetes control group, diabetic quercetin group, high-intensity interval training with diabetes group, moderate-intensity continuous training with diabetes group, diabetic high-intensity interval training with quercetin group, and diabetic moderate-intensity continuous training with quercetin group. For one training group, eight weeks of high-intensity interval training, and for the other group, eight weeks of moderate-intensity continuous training on the treadmill were performed. Seventy-two hours after the last training session, liver tissues were isolated to check the gene expression of FOXO1 and ATG5. One-way analysis of variance test was used to check the difference between groups by SPSS version 26 software.
Results: Findings showed that by inducing type 2 diabetes, gene expression of FOXO1 increased (3.14 unit) (P<0.001) and ATG5 gene expression decreased (0.71 unit) (P<0.001). After eight weeks of training investigation, gene expression of FOXO1 and ATG5 decreased (P<0.001) and increased (P<0.001), respectively, in all training groups compared to the diabetic control group. There was no significant difference between the four training groups (P>0/05).
Conclusion: Both exercises with and without quercetin had a modulating effect on the gene expression of indicators related to the process of autophagy and blood glucose levels in the liver of diabetic obese rats.

Abstract
Background: Insufficiency of omentin-1 and 25-hydroxyvitamin D serum levels is associated with obesity, which is known as a threat to health. Therefore, the aim of the present study was to examine the effect of eight weeks of Pilates exercise on the serum levels of 25-hydroxyvitamin D, omentin-1, and lipid profile in overweight women.
Methods: In the present clinical study, 26 young overweight women were divided (block randomization method) into the Pilates exercise (PT, n= 13) and control group (CG, n= 13). The PT group performed Pilates exercises for eight weeks (three 60-min sessions per week). The movements started from simple and then increased in intensity and complexity based on the Borg index. The CG group had no training session for eight weeks. Blood samples were taken before the first training session and 48 hours after the last training session. Analysis of covariance was used for between-group comparisons.
Results: Findings showed a significant increase in the serum levels of 25-hydroxyvitamin D (p=0.008, SD= 4.78±0.12 ng/ml, effect size= 0.243) and HDL-C (p=0.04, SD= 6.44±1.05 mg/dl, effect size= 0.168), but a significant decrease in HOMA-IR (p=0.001, SD= 1.54±0.09, effect size=0.199), cholesterol (p=0.001, SD= 16.72±3.24 mg/dl, effect size= 0.326), and triglyceride (p=0.001, SD= 2.46±0.07 mg/dl, effect size= 0.209), and no significant change in omentin-1 (p=0.65, SD= 3.01±0.08 ng/ml) and LDL-C (p=0.58, SD= 2.46±0.07 mg/dl) serum levels in the PT group compared to the CG group.
Conclusion: It seems that this type of exercise training may play a critical role in controlling the health parameters and physiological status of the overweight women by having positive effects on serum levels of 25-hydroxyvitamin D and lipid profile, which are affected by body composition, weight, and fat.

Abstract
Background: Mitochondrial function is an integral part of glucose-stimulated insulin secretion in pancreatic β-cells and is a hallmark feature of cardiovascular disease. It may contribute to the pathophysiology of diabetic cardiomyopathy and atherosclerosis. This study aimed to investigate the effect of high-intensity interval training (HIIT) and moderate-intensity continuous training (MICT), combined with quercetin supplementation (eight weeks), on mitochondrial gene expression in the diabetic heart.
Methods: In this study, 35 adult male rats were equally divided into seven groups (n=5): healthy sedentary, diabetic sedentary, diabetic quercetin sedentary, diabetic HIIT (DHIIT), diabetic MICT (DMICT), DHIIT with quercetin, and DMICT with quercetin. The rats were fed a high-fat diet for eight weeks and subsequently treated with a single low dose of streptozotocin to create a model of type 2 diabetes mellitus (T2DM). Eight weeks (five times a week) of HIIT and MICT, with and without quercetin, were conducted for the training groups, and quercetin was injected over eight weeks at a dose of 15 mg/kg.
Results: Eight weeks of quercetin supplementation, HIIT, and MICT, with and without quercetin, significantly decreased blood glucose levels (P=0.001). Eight weeks of HIIT and MICT training increased nuclear respiratory factor-2 (NRF2) (P=0.001) and adipose triglyceride lipase (ATGL) (P=0.001) expression and decreased perilipin 2 (PLIN2) gene expression (P=0.001).
Conclusion: The training groups alone improved the gene expression of NRF2, ATGL, and PLIN2. Both training protocols, combined with quercetin, controlled blood glucose levels and improved antioxidant capacity. Thus, the reduction in blood glucose through quercetin supplementation appears to be a promising approach for managing T2DM.
