Abstract
Background: The hepatokines are now considered potential targets for the treatment of type 2 diabetes disorders. The aim of this study was to investigate the effect of 12 weeks combined training with Canagliflozin on some hepatokines in type 2 diabetic men.
Methods: In this quasi-experimental study, 44 men with type 2 diabetes (Mean age 33.2 ± 4.5 years, body mass index 27.3±3.0) from Tehran city in 2019 were randomly divided into four groups (n=11) of control, drug, exercise and exercise-drug groups. Combined training was performed 3 sessions per week, 45 minutes for 12 weeks. Subjects were given 200 mg of canagliflozin for 12 weeks. Blood samples and anthropometric characteristics were obtained before and 24 hours after the intervention at 12-hour fasting. Data were analyzed using two-way ANOVA with repeated measures, t-test and Bonferroni post hoc test at P<0.05.
Results: The results showed that 12 weeks of exercise with Canagliflozin intervention significantly reduced angiopoietin-3 and angiopoietin-4, FGF-21 and HFREP-1 levels in type 2 diabetic men (P=0.001). Also, after the intervention of exercise with Canagliflozin, levels of angiopoietin-3, angiopoietin-4, FGF-21, and HFREP-1 were significantly lower than the pre-test (P<0.001).
Conclusion: According to the results of research, it is possible that intervention of exercise with Canagliflozin can help treat of disorders due to type 2 diabetes by reducing hepatokines.

Abstract
Background: Imbalance of apoptotic factors plays important role in pathogenesis of diabetes. Considering the role of curcumin supplementation and high-intensity interval training (HIIT) on these factors, the aim of this study was to investigate effects of four weeks of HIIT with curcumin supplementation on Bax and Bcl-2 gene expression in the soleus muscle of diabetic rats.
Methods: Present study was experimental research. 30 male Wistar rats were divided into one normal control (NC), and four diabetic groups: control (DC), supplement (SDC), high-intensity interval training (DHIIT) and high-intensity interval training supplement (SDHIIT). The training protocol was performed five days a week for four weeks, which included five to seven two-minute intervals at 80 to 90% of maximum power until exhaustion and one-minute recovery at 30% of maximum power until exhaustion. At the same time, Curcumin gavage at a dose of 100 mg/kg was performed daily. Bax and BCL-2 gene expression levels were measured by the qReal-TimePCR method and data were analyzed by two-way analysis of variance at a significant level of p≥0.05.
Results: Bcl-2 gene expression was significantly increased in DHIIT and SDHIIT groups compared to DC (P= 0.000). Also, a significant decrease in Bax gene expression was observed in DHIIT and SDHIIT groups compared to DC (P=0.000). There was a significant difference between DHIIT and SDHIIT in Bcl-2 (P=0.000) and Bax (P=0.013) gene expression.
Conclusion: It seems that HIIT in combination with curcumin supplementation, is more effective in improving the balance between apoptosis factors than any of these interventions alone.

Abstract
Background: The formation of islet amyloid polypeptide (IAPP) have been proposed for d increased b-cell apoptosis in type 2 diabetes. Exercise training plays a protective role against diabetes. Alpha lipoic acid (ALA) is a powerful biological antioxidant. However, the role of exercise training and ALA on IAPP are not well understood. The aim of the present study was to investigate the effect of training with different intensity and Alpha lipoic acid supplement on pancreatic mRNA IAPP in rats with type 2 diabetes.
Methods: In this experimental study, 35 wistar rats were randomly divided into seven groups: control, diabetic (D), diabetic+ alpha lipoic acid (ALA), diabetic high intensity training (HIT), diabetic moderate intensity training (MIT), diabetes HIT+ALA (ALA+HIT), diabetic MIT +ALA (ALA+MIT). The HIT and MIT protocols was performed five days a week for six weeks. HIIT included 10 bouts of four minutes (running at 85–90% of VO2max) and MIT 13 bouts of four minutes (running at 65–70% of VO2max). ALA was administered orally 20 mg/kg once a day by gavage. Real-time PCR method for the relative expression of mRNA of IAPP gene were used.
Results: The level of IPAA increased significantly in diabetic group compared to control (p=0.0039). Also, level of IPAA decreased significantly in ALA (p=0.01) and ALA+HIT diabetic group (p=0.021).
Conclusion: diabetes is associated with increased mRNA IAPP in pancreatic b-cell and HIT plus ALA can be as an effective intervention in decreasing IAPP in pancreatic b-cell. in diabetics.

Abstract
Background: FOXO family proteins are important factors in autophagy
pathway. Protein kinase-B is an important regulator for this family that can be regulated through exercise training. Therefore, the aim of this study is to investigate the effect of protein
kinase-B (PKB) on FOXO autophagy family proteins (FOXO1 and FOXO3a) following
high intensity interval training (HIIT) in the left ventricle of the heart of diabetic rats by streptozotocin (STZ) and nicotinamide.
Methods: In this experimental study, 12 two-month-old Sprague-Dawley rats with a mean weight of 270±20 g were selected. After type 2 diabetes induction with STZ and Nicotinamide, rats were randomly assigned to two groups, diabetic training (6 heads) and diabetic control (6 heads). The training group trained for 4 days a week in accordance with the training program for 8 weeks. SPSS software version 23 and independent t-test were used to analyze the data. Significance level is considered p≤0.05.
Results: HIIT training resulted in a significant increase in PKB protein content between training and control groups (P=0.0001). In contrast, a significant decrease in protein content of FOXO1 (P=0.003) and FOXO3a (P=0.006) was observed between the training and control groups.
Conclusion: It seems based on the results
HIIT with increasing and regulating PKB leads to a decrease and inactivation of FOXO1 and FOXO3a proteins in the hearts of diabetic subjects. Inhibition of these proteins can prevent excessive cardiac autophagy in diabetic subjects.

Abstract
Background: Imbalanced production of adipokines as leptin and adiponectin in diabetic patients may lead to the development of metabolic complications. Therefore, the aim of this study was to determine the effects of 2-month of caffeine ingestion along with aerobic training on changes in serum leptin and adiponectin levels and leptin/adiponectin ratio (LAR) in type 2 diabetic men.
Methods: Thirty-two diabetic men participated in
a quasi-experimental designs in the four groups for two-months period of a aerobic training (treadmill walking 3 times/week, 1.5 hour/session, 65-85% HRR) with and without caffeine ingestion (3 mg.kg
-1.day). Serum changes in leptin and adiponectin were measured during two phases (baseline and 24-hours after completing of the training program). Data were analyzed by one-way ANOVA and bonferroni's post-hoc test at level P≤0.05.
Results: Administration of two-months caffeine (CA) alone and combination with aerobic training (AT) were significantly could reduced and increased in leptin and adiponectin level, respectively (P=0.001). Thus, the combined group (AT+CA) effect were far more appropriate intervention in changing the studied indices (P=0.001). Also, the LAR method was notable reduced in all study groups, although these effects were more significantly in the combined group (AT+CA) (P=0.001).
Conclusion: It seems administration of caffeine supplementation and aerobic training for two-months have a positive effects on the improved relative of leptin and adiponectin levels as well as their ratio in diabetics, although the combination of these two variables has been shown to have far more dual effects.

Abstract
Background: Diabetes is one of the most common chronic diseases in today's society. The aim of this study was to investigate the effect of endurance training and nettle consumption on the protein and gene expression of AKT, GLUT4 and insulin in male of muscle soleus of diabetic rats.
Methods: After adaptation to the environment, 40 male Wistar rats were divided into 5 groups: control (C), diabetes (D), nettle+diabetes (UD), exercise+diabetes (ED) and exercise+nettle+diabetes (EUD). After developing and confirming the diabetes model by injection of STZ, rats in the exercise groups performed an endurance training protocol for eight weeks and rats in the nettle groups consumed nettle extract 5 days a week. After completion of the protocol and extraction of soleus muscle, RT-PCR method was used to measure gene expression, Western blot and immunohistochemically method was used to measure protein expression of glut-4 and AKT respectively and ELIZA method was used to measure glucose and insulin.
Results: The results showed that the protein and genes expression of GLUT4 and AKT in the diabetic group compared to the control group was significantly reduced (P<0.001) while the expression of these two variables was significantly increased in the ED and EUD groups (P<0.001) that this increase was greater in the EUD group. The effect of nettle alone on the expression of these two variables was not significant. Glucose, insulin and insulin resistance increased significantly in the diabetes group, while these decreased significantly in the ED and EUD groups (P<0.001).
Conclusion: The synergist of the combination of nettle and exercise significantly improves the improve of diabetes, while each alone has little effect on diabetes-related variables.

Abstract
Background: The objective of this experimental study was to determine the effect of 6 weeks of high intensity interval training (HIIT) on G6Pase expression in liver tissue, serum insulin and glucose and insulin resistance in obese rats with type 2 diabetic and compared with non-diabetic obese group.
Methods: 28 male Wistar rats aged 10 weeks (220 ± 10 g) were obesed by 6 weeks of high-fat diet (HFD). Then type 2 diabetes induced in 14 rats by intraperitoneal injection of STZ (30 mg/kg). Finally, the studied rats were divided into 4 same groups: 1) control obese, 2) interval obese, 3) control diabetic, 4) interval diabetic. Interval groups participated in an interval exercise program of 5 sessions per week for 6 weeks consists of 10 repetitions of a 40-second run on the treadmill with 2-minute rest (active rest) between repetitions. 48 hours after the lasting session, fasting levels of glucose, serum insulin and G6Pase expression in liver tissue in all 4 groups were measured and compared with 2 way ANOVA.
Results: Compared with diabetic control groups, HIIT in diabetic group resulted in significant decrease fasting glucose (p= 0.001). HIIT also led to an increase in serum insulin (p= 0.006) without change in G6Pase expression (p= 0.102) compared to the diabetic control group.
Conclusion: Improved glucose response to interval training in type 2 diabetic rats may be rooted in increase insulin without changes in hepatic G6Pase expression. Measurement of activity or expression of other liver enzymes is suggested for general conclusion.

Abstract
Background: The apoptosis process as a common status in heart injuries could be imposed significantly by hyperglycemia chronically. Therefore, the aim of this study was to investigate the inhibitory effects of concurrent training and antioxidant supplementation individually and in combination on
biogenesis and function of mitochondrial in the heart tissue of
diabetic rats with STZ.
Methods: In this experimental study, fifty male Sprague Dawley rats were classified into five groups (n=10 each group): healthy rats as control, diabetic rats, diabetic combined resistance/endurance training, diabetic rats which consumed supplementation vitamin E and C, and the combined supplementation and training. Here, we calculated changes in genes expression based on artificial intelligence methods and evaluated genes expression in apoptotic influencing combined training and antioxidants vitamins consumption in heart injured models by streptozotocin via Real-Time PCR. Combination training including, respectively, resistance training, 5 days a week with increasing intensity of 5-45% of rat weight and endurance training on treadmill increasingly from 10-30 minutes and intensity of 40-75% of maximum speed during 8 weeks. Data were analyzed by two-way ANOVA (P<0.05).
Results: the relative expression of PGC1α and Tfam were significantly decreased between healthy control and diabetes controls group. The results indicated that significantly increased of PGC1α and Tfam in the training(P<0.05), supplement(P<0.05) and combination groups(p<0.05). In addition, in this study, it was observed that supplementation and exercise had an increasing effect on the expression of PGC1α and Tfam genes. On the other hand, glucose concentration and weight of rats treated with supplementation and exercise were significantly reduced compared to other groups (P<0.05).
Conclusion: Based on the results, interaction between antioxidant supplements and exercise reduced the glucose concentration and improved the mitochondrial biogenesis of heart tissue, while the combination of these two interventions compared to the effect of each alone, the effect has more.

Abstract
Background: Because insulin therapy cannot properly control the progression of diabetes and its complications, other alternative therapies may be desirable. The aim of this study was to investigate the effect of resistance training and endothelial stem cell injection on skeletal muscle oxidant and antioxidant status in STZ-induced diabetic male rats.
Method: In this experimental study, 36 male Wistar rats (age 6 weeks) were divided into six groups of control (healthy), basal diabetic control, diabetic control, diabetes + stem cell injection, diabetes + resistance training and diabetes + stem cell injection + resistance training. In this study, rats became diabetic intraperitoneally using streptozotocin as a single dose of 40 mg/kg. Resistance exercises including climbing a one-meter ladder with weights hanging from the tail were performed for 17 sessions. 500,000 bone-derived stem cells were injected by a cell counter. The levels of superoxide dismutase (SOD) and malondialdehyde (MDA) in skeletal muscle tissue of rat were measured by using the kit and ELISA method.
Results: The results showed that the SOD level of rats in the resistance training and endothelial stem cell injection group was significantly higher than the diabetic control group (P<0.001). Also, the level of MDA rats in the resistance training and endothelial stem cell injection group was significantly lower than the control group (P<0.001).
Conclusion: Resistance training and endothelial stem cell injections can be considered as a non-pharmacological treatment to reduce skeletal muscle complications in type 1 diabetes.

Abstract
Background: Diabetes is an important factor in heart defects that can lead to atrophy of heart cells. Exercise can prevent the complications of diabetes by regulating cellular factors. Therefore, the aim of the present study was to evaluate the effect of endurance and
high-intensity interval training on the content MSTN and Follistatin proteins in the left ventricular tissue of the heart of type 1 and 2 diabetic rats
Methods: In this study, 36 head 2-month-old male Sprague-Dawley male rats with a mean weight of 280±30 g were selected.
After induction of type 1 (18 head) and 2 (18 head) diabetics through streptozotocin and nicotinamide solution, each type of diabetes was randomly divided into 3 groups: endurance training, HIIT and control (6 heads per group); The training groups performed endurance (50 to 70% of maximum speed) and HIIT (intensity 85 to 95% of maximum speed) training program 4 days a week for 4 weeks; Data analysis was performed by one-way ANOVA and Tukey post hoc tests in SPSS software.
Results: Endurance training and HIIT in diabetic training groups led to a significant decrease in MSTN protein content (P=0.0001) and an increase in Follistatin protein content (P=0.0001).
Conclusion: It seems that four weeks of endurance
training and HIIT can prevent excessive myocardial atrophy by decreasing the MSTN content and increasing
Follistatin. Therefore, exercise training with the intensity, duration and type can be a good defense and treatment mechanisms for diabetics to prevent or reduce heart complications.

Abstract
Background: Artificial intelligence analysis based on the gene list obtained from the DisGeNET database identified the important genes involved in the heart damage process. Data enrichment highlighted the apoptosis signaling pathway as a vital pathway in cardiovascular risk. Hence, we estimated the binding affinity of chemical and plant bioactive molecules for cytochrome-c protein. Here, we performed to evaluate the effect of eight weeks of resistance training (RT) with Tribulus Terrestris (TT) consumption on the mechanism of apoptosis in the heart tissue of rats exposed to stanozolol.
Methods: Thirty-five male rats were divided into seven groups: (1) Control, (2) Stanozolol (ST), (3) ST + 100 mg / kg TT, (4) ST + 50 mg / kg TT, (5) ST + RT (SRT), (6) S + RT + 100 mg / kg T (SRTT100), and (7) ST + RT + 50 mg / kg T (SRTT50). Differential gene expression was measured by q-RT-PCR. In bioinformatics analysis, the apoptosis signaling pathway was defined as a critical process in heart damage. In addition, adverse effects of Tribulus Terrestris and stanozolol on heart tissue were detected through the apoptotic pathway by molecular docking.
Result: Resistance training along with 100 mg/kg reduced CRP and cytochrome-c Moreover, 100 mg/kg TT as a more favorable effect than 50 mg/kg TT
Conclusion: we showed the beneficial effects of Tribulus Terrestris, the plant’s bioactive compound that can reduce cardiovascular risks by impairing the formation of apoptosome assemblages and inflammation.

Abstract
Background: Diabetes is the most common glandular disease in the world. The aim of this study was to compare the effect of three types of endurance, resistance and combination training on inflammation and insulin resistance in visceral adipose tissue of type 2 diabetic rats.
Methods: For this purpose, among eight-week-old male Wistar rats, 48 rats were selected and randomly divided into 6 groups (diabetic endurance training, diabetic resistance training, diabetic combination training, healthy combined training, healthy control and diabetic control). The rats became diabetic by injecting 95 mg of nicotinamide and after 15 minutes of STZ injection at the rate of 55 mg/kg body weight. 4 days after injection, rats with serum glucose above 300 mg/dL were considered diabetic. Then, the endurance training group trained for 6 weeks, 3 sessions per week with moderate intensity (50-60% of maximum oxygen consumption). The initial load to start resistance training was 50% of the rat's body weight. Each session added 15% of body weight to the weights. The combined exercise group also performed resistance and endurance exercises in a row. 48 hours after the last session, the rats were anesthetized and visceral adipose tissue was removed to examine the variables.
Results: The results showed that there was a significant difference between the effect of six weeks of endurance, resistance and combined exercise on inflammation and insulin resistance in the visceral adipose tissue of male diabetic mice.
Conclusion: The results confirm the effect of three training methods on the mechanisms involved in diabetes.

Abstract
Background: Angiogenesis disorders are known mechanisms of diabetes. With the aim of reducing angiogenesis disorders, resistance training and its combination with endothelial progenitor cell injection are new strategies. Therefore, the present study was performed to determine the effect of resistance training with endothelial progenitor cell injection on the expression of angiogenic factors in the skeletal muscle of diabetic rats.
Methods: In this study, 30 rats were randomly divided into 5 groups: healthy, control (D) diabetic, trained diabetic (DR), endothelial progenitor cell (DI) diabetic, trained endothelial progenitor cell (DRI) diabetic) Were divided. Ang1 and Tie2 protein expression changes were measured by Western blotting. Data were analyzed using two-factor analysis of variance with SPSS software version 19 at a significance level of 5% α≤.
Results: In this study, 6 weeks of resistance training led to a significant increase in Ang1 and Tie2 proteins. But injection of endothelial progenitor cells was significant only on the amount of Tie2 protein. The interactive effect of resistance training and endothelial progenitor cell injection was significant only on the amount of Tie 2 protein. In other words, the combination of resistance training and endothelial progenitor cell injection was superior to Tie2 protein expression than training or injection alone.
Conclusion: It can be said that resistance training improves angiogenesis in diabetics. Combining resistance training with endothelial progenitor cell injections could possibly stimulate angiogenesis in skeletal muscle and be a new strategy in the treatment of diabetic disorders.

Abstract
Background: The aging process is usually accompanied by a decrease in the function of the body's systems and physiological capacity, along with an increase in susceptibility to diseases, especially metabolic syndrome. This study looked at the effect of eight weeks of resistance training on levels of Irisin, IL-15, CRP, and Cholesterol in elderly men with metabolic syndrome.
Methods: The statistical population was elderly men in Khorramabad, of whom 18 were selected and randomly divided into two experimental groups and control (65/2±2/2, 65/4±2/1). The exercise program included leg presses, chest presses, row movements, bending the knees, head, back of the arm, opening of the knees and front of the arm. The above program started with 30% of a maximum repetition and reached 50% of a maximum repetition at the end of the eighth week. Blood samples were taken 48 hours before and after the training sessions. Correlated t-test and independent t-test were used to examine the research data. The level of significance was also considered (P<0.05).
Results: Eight weeks’ resistance exercise significant increase in Irisin (P=0.01) and interleukin-15 (P=0.007), as well as a significantly decreased levels of CRP (P=0.007) and total cholesterol(P=0.02) in elderly men with metabolic syndrome.
Conclusion: Finding non-pharmacological solutions to improve metabolic indicators is very important. Based on the results of research, doing resistance exercises is recommended as a low-cost and non-pharmacological solution for the treatment of metabolic syndrome in elderly men.
