Abstract
Background: Exercise and the simultaneous use of progenitor cells is a new strategy aimed for reducing diabetic disorders. One of the known mechanisms is angiogenic disorders caused by diabetes. Therefore, the present study was performed to determine the simultaneous 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, diabetic control (D) trained diabetic (DR), diabetic with endothelial progenitor cell injection (DI), diabetic trained with endothelial progenitor cell injection (DRI) were divided. VEGF protein expression was measured by Western blotting and insulin resistance index was measured by ELISA. The data were analyzed using two-factor analysis of variance test with SPSS software version 19 at a significance level of 5%.
Results: In this study, 6 weeks of resistance training or progenitor cell injection caused a significant increase in VEGF and a significant decrease in insulin resistance index in diabetic rats. In the group that used simultaneous exercise and injection compared to the group with exercise and injection and these changes were significant in the group of simultaneous use of exercise and injection compared to the group of exercise with injection.
Conclusion: Based on the results of this study, it can be stated that resistance training or injection of endothelial progenitor cells can stimulate angiogenesis in skeletal muscle, also the simultaneous use of these two factors is a better way to increase angiogenesis in rats

Abstract
Background: Diabetes disorders can lead to muscular burnout. The aim of this study was to determine the simultaneous effect of resistance training and endothelial stem cell injection on the factor of degeneration in the muscles of diabetic rats.
Methods: 36 male wistar rats (age 6 weeks with weight of 20±200g) were randomly divided into five groups of basic healthy, diabetic control (D), diabetic and resistance training (DR), untrained diabetic by injection of endothelial stem cells (DI), diabetic training by simultaneous injection of endothelial stem questions (DRI). Western blotting and insulin resistance index were measured by ELISA method to evaluate the changes in MURF1 expression. The data were analyzed by two-factor analysis of variance by SPSS software version 19 at a significant level of α≥%5.
Results: In this study, 6 weeks of resistance training significantly reduced MURF1 and insulin resistance index. The interactive effect of resistance training and stem cell injection also resulted in a significant decrease in murf1 levels, but insulin resistance index was not significantly superior to only training or injection.
Conclusion: Based on the findings of this study, it can be stated that resistance training or injection of endothelial ancestral cells can improve muscular degeneration, but simultaneous use of these two strategies was not superior in reducing atrophy complications in diabetic rats.

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: 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 aim of the present study was to investigate the simultaneous effect of resistance training and stem cell injection on the levels of some indicators of skeletal muscle apoptosis in STZ-induced diabetic male rats.
Methods: In this study, 30 rats were randomly divided into 5 groups. Rats in the diabetic group and the diabetic group + stem cell injection had a total of 17 sessions of resistance training for 5 weeks. The training period for rats with this type of training was 3 days, which was done 48 hours before STZ injection. Western blotting was used to evaluate the changes in Caspase7 and caspase3. The data were analyzed using two-factor analysis of variance test with SPSS software version 19 at a significance level of α≤ 5%.
Results: The results of the present study showed that there was no significant difference between the mean of caspase3 in the resistance training group with simultaneous injection of stem cells and the training group. Also, resistance training with simultaneous injection of endothelial stem cells, compared to resistance training or injection alone, led to a significant reduction in Caspase7 expression in skeletal muscle tissue of diabetic rats.
Conclusion: Based on the results of this study, it can be stated that resistance training or injection of endothelial progenitor cells can stimulate apoptosis in skeletal muscle.

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.

Abstract
Background: Diabetic disorders can lead to muscle atrophy. The aim of this study was to investigate the combination of resistance training and endothelial progenitor cell injection on the expression of horseshoe muscle atrophy factor in diabetic rats.
Methods: 30 rats (6 weeks old weighing 200 20 200 g) were randomly divided into five groups: healthy baseline, control diabetic, trained diabetic, non-trained diabetic by endothelial progenitor cell injection, diabetic trained by simultaneous injection Endothelial progenitor cells were divided. Heat 25 was measured by Western blotting to evaluate changes in protein expression. Data were analyzed by two-factor analysis of variance test by SPSS software version 19 at a significance level of α≥ 5%.
Results: In this study, 6 weeks of resistance training had no significant effect on the expression of heat shock protein 25. But injection of endothelial progenitor cells resulted in a significant increase in the expression of heat shock protein 25. The interactive effect of resistance training and progenitor cell injection on heat shock protein 25 was not significant, in other words, there was no significant superiority over training and injection at the same time as training or injection alone.
Conclusion: Based on the findings of this study, it can be stated that injection of endothelial progenitor cells can improve muscle wasting but resistance training alone was not effective. Also, the combination of these two strategies was not superior in reducing the complications of atrophy in diabetic rats.

Abstract
Background: Type 1 diabetes is associated with decreased skeletal muscle capillary and improper regulation of angiogenesis pathways in skeletal muscle. This research intended to study the effect of resistance training and endothelial stem cell injection on βeta-actin, phosphorylated and total AKT of skeletal muscle in type 1 diabetic rats.
Methods: 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 βeta-actin, phosphorylated and total AKT in skeletal muscle tissue of rat were measured by using the Western blotting method.
Results: The results showed that resistance training led to significant increase in Pho-AKT, β-actin and Pho-AKT/AKT ratio and significant decrease in AKT of muscle tissue in type 1 diabetic rats (P<0.001). Injection of stem cells leads to significant increase in Pho-AKT and Pho-AKT/AKT ratio and resistance training with simultaneous injection of stem cells leads to significant increase in Pho-AKT, β-actin and significant decrease in Akt of muscle tissue in type 1 diabetic rats (P<0.001).
Conclusion: According to the results, it is possible that the intervention of resistance training with injection of stem cells can help regulate the pathways of skeletal muscle angiogenesis in type 1 diabetes.

Abstract
Background: Diabetes, as a progressive disease, can lead to decreased immune function. therefore, the aim of this study was to determine the simultaneous effect of resistance training and endothelial progenitor cell injection on immunoglobulins (IgA, IgM, IgG) of streptozotocin-induced diabetic rats.
Methods 30 rats (aged 6 weeks with a mean weight of 200±20 g) were randomly divided into groups including Diabetes + stem cell injection + resistance training (n = 6), diabetes + resistance training (n = 6), diabetes + stem cell injection (n = 6), control diabetes (n = 6) and healthy basal (n = 6) Were divided. Western blotting was used to evaluate the changes in immunoglobulins. Also, two-way analysis of variance was used for comparison between and within the group, and for better understanding of the results, the effect size, and the amount of 95% confidence interval were given.
Results: The results showed that IgA (P = 0.022), IgM (P = 0.017), IgG (P = 0.045) had significant changes between groups. Also, there was a significant difference in all three variables between the control diabetes group and the diabetes + resistance training + injection group (P≤0.05).
Conclusion: Summarizing the results of the present study, it can probably be said that resistance training and simultaneous injection of endothelial progenitor cells improve the status of immunoglobulins by training and injection. These findings suggest that resistance training and injections can be used as a treatment to improve the function of the immune system due to diabetes.

Abstract
Background: Damage to the heart tissue in diabetics causes inflammation and destruction of heart cells, which in turn leads to apoptosis or cell death. The aim of this study was to investigate compare the effect of six weeks of aerobic and resistance training on apoptotic indice of caspase-8 and catalase in the heart tissue of male diabetic rats.
Method: In this experimental study, 24 male Wistar rats were divided into six groups: aerobic training, resistance training, aerobic sham, resistance sham, control and healthy. Diabetes was induced by intraperitoneal injection of a single dose of streptozotocin in the amount of 30 mg per kg. The aerobic and resistance training program was performed for six weeks. Western blotting was used to measure caspase-8 and catalase. Data were analyzed by one-way analysis of variance and Tukey post hoc test at the P<0.05.
Results: The results showed that the mean difference of caspase-8 between aerobic training group and healthy group (P=0.752), resistance training group with healthy group (P=0.723) and resistance training with aerobic training group (P=1.00) were significant. Caspase 8 was lower in the aerobic exercise group than in the resistance exercise group. The difference between the mean catalase between the aerobic training group with the healthy group (P=0.024) and the aerobic training group with the resistance training group (P=0.023) was significant and the amount of catalase in the resistance training group was higher than aerobic training.
Conclusion: Aerobic and resistance training can reduce the apoptotic index of caspase-8 and increase catalase in the heart tissue of diabetic rats.

Abstract
Background: Diabetic myopathy is one of the major problems in people with type2 diabetes that knowing its mechanisms can be helpful in controlling and preventing this disease. PAX7 and PGC-1α are two proteins involved in the renewal and metabolism of carbohydrates in skeletal muscle. The aim of this study was to evaluate the effect of 8weeks of resistance training under hypoxia on the content of PAX7 and PGC-1α proteins in the horseshoe muscle of type 2 diabetic rats.
Methods: In this study, 40 male Wistar rats, 10weeks after induction of type2 diabetes, were divided into five groups: healthy control (HC), diabetic control (DC), resistance training (RT), and resistance training in hypoxia (RT-HPX) and hypoxia group (HPX) were divided. Resistance exercises were performed for 8 weeks, 5 sessions per week, in the groups of resistance training and resistance training in hypoxia. The intensity of the exercises started from 30% of the weight of the rats initial and reached 100% of their weight until the end of the training. Resistance training in hypoxia. Hypoxia tent with14.4%oxygen was used to create hypoxia. 48hours after training, tissue samples were taken from horseshoe muscle and evaluated to measure the concentration of PAX7 and PGC-1α proteins.
Results: The results showed that there is a significant difference (P=0.0001) between the research groups in both PAX7 and PGC-1α proteins. Induction of diabetes led to a significant decrease in PAX7, but the hypoxia resistance training group was not significantly different from the healthy control group (P=0.451). PGC1-α protein levels were also significantly decreased in the diabetes induction group compared to the control group (P=0.01), but training in hypoxia increased its levels to more than the healthy control group (P=0.0001).
Conclusion: Hypoxia, resistance training and combination of resistance training in hypoxia increased the amounts of PAX7 and PGC-1α proteins. Therefore, resistance training and temporary and inactive hypoxia exposure can be considered as a suggested solution to improve the indicators related to type2 diabetes in humans.

Abstract
Background: Type 1 diabetes is a disorder caused by autoimmune destruction of pancreatic insulin-producing cells. This induction of autoimmunity may be due to genetic and environmental factors. Bax and Bcl2 proteins play an important role in the process of apoptosis.
Methods: In this study, 30 male Wistar rats weighting approximately 200±20gr were randomly selected from available rats in lab (500). Subjects after 2 weeks of familiarity with the environment were randomly divided into 5 groups of 6, including (diabetes + injection, exercise) and (diabetes + exercise) and (diabetes + injection) and (diabetes control to control the passage of time) and (basic diabetes to Defaults) under the same laboratory conditions and developed type 1 diabetes by intraperitoneal injection of streptozotocin (stz) (60 mg / kg). Rats in the diabetic group and the diabetic group + stem cell injection had a total of 17 sessions of resistance training for 5 weeks.
Results: The results of the present study showed that there was no significant difference between the mean of Bax and Bcl2 in the resistance training group with simultaneous injection of stem cells and the training group.
Conclusion: The results of our study showed that performing 17 sessions of resistance training alone with stem cell injection was effective on the expression of Bax protein and Bcl2, but there was no significant difference between the effect of training alone and training with stem cells.

Abstract
Background: Physical activity and exercise training are known as an integral part of weight management and control in overweight or obese people. The aim of this study was to compare the effect of high intensity interval training (HIIT) and intense resistance training on asprosin and C1q/tumor necrosis factor related protein1 (CTRP1) serum levels in overweight and obese men.
Methods: In this semi-experimental study, 31 overweight and obese men were randomly divided into three groups: HIIT training (n=10), intense resistance training (n=11) and control (n=10). The subjects of the experimental groups performed HIIT exercises and intense resistance exercises three times a week for nine weeks. Before and after the intervention, blood samples were taken to measure the serum concentration of asprosin and CTRP1 from the subjects. Analysis of covariance test was used to analyze the data and the significance level was considered as p_value less than 0.05.
Results: The concentration of asprosin in the HIIT group (p=0.013) and intense resistance training (p=0.042) decreased significantly compared to the control group. No significant difference in CTRP1 concentration was observed between groups. However, the concentration of CTRP1 in the HIIT group decreased significantly in the post-test compared to the pre-test.
Conclusion: HIIT training and resistance training in overweight and obese men led to a decrease in asprosin levels. Considering the changes in asprosin, CTRP1 and other anthropometric indicators and lipid profiles, HIIT training seems to have a better efficiency in overweight and obese men.

Abstract
Background: The beneficial effects of saffron extract and resistance training on the improvement of some diabetes indices have been determined, but their combined effect on BDNF protein levels in rats with type 2 diabetes has not been investigated. Therefore, the aim of the present study was to investigate the effect of saffron extract consumption during resistance training on BDNF protein expression in the hippocampus of rats with type 2 diabetes.
Methods: In this experimental study, 30 adult male rats were randomly divided into five groups: control (C), diabetes (D), diabetes-resistance training (DT), diabetes-saffron extract (DS) and diabetes-saffron extract- resistance training (DTS). Resistance training performed five sessions/w for six weeks. Blood glucose levels and hippocampus BDNF protein levels were measured. To analyze the data, one-way ANOVA was used at the significance level of P< 0.05.
Results: Blood glucose levels of all experimental groups were significantly higher than C group (P= 0.001). Blood glucose levels in DT, DS and DTS groups were significantly lower than D group (P= 0.001). Also, the blood glucose levels of the DTS group were significantly lower than that of the DT group (P= 0.014). In addition, BDNF protein levels of all experimental groups were significantly lower than group C (P< 0.05). Also, BDNF protein levels of D, DT and DS groups were significantly lower than DTS group (P< 0.05). However, BDNF protein levels of D, DT and DS groups were not significantly different (P< 0.05).
Conclusion: Performing resistance training also consuming saffron extract alone and during resistance training reduces blood glucose levels in diabetic rats. However, consumption of saffron extract could increase BDNF protein levels only during resistance training. Therefore, for more efficiency, it is suggested to consume saffron extract during resistance training.

Abstract
Background: Alzheimer's disease is the most common type of dementia, which is associated with progressive loss of memory and reaction to the environment. The aim of this study was to investigate the effect of 12 weeks of resistance training with sumac intake on the serum levels of SIR3, SIR4 and AMPK in Alzheimer's male rats.
Methods: In this experimental study, male Wistar rats with an age of 8-10 weeks and an average weight of 230±30 grams were randomly divided into five groups: control, Alzheimer's disease, Alzheimer's disease with sumac supplementation, Alzheimer's disease with resistance training, and Alzheimer's disease with resistance training. Received sumac supplements were divided. To induce Alzheimer's disease, 8 mg/kg of trimethyl tin chloride along with 200 microliters of normal saline were injected intraperitoneally to mice. Resistance training was performed for 12 weeks and 5 days a week on a special rat ladder. 48 hours after the last training session, a blood sample was taken. Serum levels of SIR3, SIR4 and AMPK were evaluated by ELISA method. To check the changes between the control group and other groups using the independent T-test and to check the difference between the other groups using the one-way analysis of variance test and if significant, using the Tukey post hoc test, by SPSS version 29 software at a significance level of P< 0.05 used.
Results: The results of this research showed that 12 weeks of resistance training increases the levels of SIR3 (P< 0.036), SIR4 (P< 0.029) and AMPK (P< 0.447) compared to the Alzheimer group. In addition, adding sumac to the resistance training program had a significant effect on the levels of SIR3 (P< 0.078), SIR4 (P< 0.024) and AMPK (P< 0.002).
Conclusion: Our results suggest that resistance training is associated with the improvement of sirtuin 3, sirtuin 4 and adenosine monophosphate kinase levels in Alzheimer's rats and receiving sumac antioxidant compound leads to doubling of these responses.

Abstract
Background: Endoplasmic reticulum stress leads to unfolded or folded protein response, and ATF4 and CHOP proteins play very important roles in this signalling pathway; Therefore, the aim of this research is the effect of resistance training on the content of ATF4 and CHOP proteins in the left ventricle of the heart of type 2 diabetic rats.
Methods: In this experimental study, 12 two-month-old male Sprague Dawley rats were selected and their weight reached an average of 280±20 gr after four weeks. Type 2 diabetes was induced by injecting nicotinamide solutions (110 mg/kg) and streptozotocin (60 mg/kg). The rats were randomly divided into 2 groups, resistance training and diabetic control; Resistance training consisted of 8 weeks and 3 sessions per week of climbing a vertical ladder with an 85-degree slope, one meter long with 26 steps and 2 cm space between each step. To analyze data, independent t-test was used in SPSS version 29 and Graphpad Prism version 10.2.3. A significance level of P≤0.05 is considered.
Results: The content of ATF4 and CHOP proteins after 8 weeks of resistance training showed a significant change compared to the control group in the left ventricle of the heart (P=0.001).
Conclusion: The increase of ATF4 and CHOP proteins can lead to increased cell death of cardiomyocytes in the left ventricle of the heart of type 2 diabetic subjects through increasing the endoplasmic reticulum stress and initiating the unfolded or folded protein response.

Abstract
Background: Obesity is known to have metabolic complications including insulin resistance (IR) and metabolic disorder. The aim of this study was to compare the effect of two traditional 12-week circular resistance training methods on the levels of branched and aromatic amino acids and insulin resistance of overweight and obese men.
Methods: The current research method is of the clinical trial type, with Thirty-three overweight and obese men with mean and standard deviation of age, weight and body mass index were 17.7±0.13 years, 92±2.45 kg and 30.70±32 1.32 kg / m2, respectively. They were selected and randomly divided into three groups: circular resistance training (n= 11), traditional resistance training (n= 11) and control (n= 11). The training program consisted of two traditional resistance training protocols and 12-week wave circuits that were exactly the same volume; Which was run three times a week. Blood sampling was performed 48 hours before and after the training protocol and after 8 hours of fasting. HPLC was used to measure serum levels of amino acids.
Results: The results of analysis of variance in the groups showed that circuit training more than 2 times compared to traditional training reduces total BCAAs (35.9 vs. 15.5%) and AAAs in serum (19.5 vs. 9%) and equally the level of insulin resistance. (23 and 26.7 percent, respectively) reduced the door in overweight and obese young men.
Conclusion: The results of this study showed that the level of changes in circular resistance training was higher than traditional. Circular resistance training may be able to prevent obesity-related metabolic disorders.

Abstract
Background: The aim of this study was to determine effect of resistance training on the expression of PI3K, AKT1 and mTORc1 in the heart tissue of type 2 diabetes rats and their physiological cardiac hypertrophy.
Methods: 21 male wistar rats (220±20 g) were obese by 6 weeks high fat diet (HFD). After inducing obesity, T2D induced by intraperitoneal injection of streptozotocin (30 mg/kg) in 14 rats. Finally, the rat were randomly assigned to 1) non-diabetes, 2) control T2D, 3) resistance diabetes groups. Rats in the resistance group were completed a resistance
training program, 5 sessions weekly for 6 weeks. PI3K, AKT1 and mTORc1 expression and the weight ratio of left ventricular to heart, left ventricular to body and heart to body were compared by ANOVA between groups.
Results: In response to induction of diabetes, the expression of PI3K, AKT1 and mTORc1 in heart tissue decreased significantly compared to the non-diabetic group (p < 0.05). Resistance training resulted in significant increase in the expression of PI3K, AKT1 and mTORc1 and the weight ratio of left ventricular to heart, heart to body and left ventricular to body compared to control diabetes rats (p < 0.05).
Conclusion: Resistance training is associated with physiological cardiac hypertrophy in diabetic rats, and this improvement can be attributed to the PI3K/AKT1/mTORc1 signaling pathway.

Abstract
Background: Today, obesity is closely related to metabolic syndrome and especially type 2 diabetes, which changes the secretion and release of adipocytokines, and different training programs have different results on these indicators. Therefore, the aim of the present study is to investigate the durability of changes caused by exercise programs on adipocytokine indices of obese type 2 diabetic patients.
Methods: In this semi-experimental study, 45 obese men with type 2 diabetes were randomly divided into a control group (no exercise) and 4 exercise groups (aerobic, combined, resistance and high-intensity interval). The exercise program of the groups was considered based on the calories consumed in each session. The participants performed 12 weeks of training programs and 12 weeks of non-training. Physiological, anthropometric indicators and inflammatory and pro-inflammatory indicators (IL-6, TNF-α, resistin and leptin) and anti-inflammatory indicators (adiponectin and SFRP5) were measured before the program and at weeks 6, 12, 18 and 24. became.
Results: After 12 weeks of combined, aerobic, high intensity and resistance training, anti-inflammatory indices (adiponectin and SFRP5) showed a significant increase compared to the baseline (before starting the training program) (P< 0.05). Regarding pro-inflammatory and anti-inflammatory indicators (IL-6, TNF-α, resistin and leptin), a significant decrease was observed in all groups after 12 weeks of training program (P< 0.05). In this study, a significant improvement in weight loss and blood glucose was observed after 12 weeks of exercise program in all 4 exercise groups (P< 0.05). In the second part of the findings (non-training or durability of training effect), it was resistance training that showed a lower percentage decrease (P< 0.05) in anti-inflammatory indices and an increase in pro-inflammatory and inflammatory indices after 12 weeks of non-training, which showed the durability It shows more recovery in obese type 2 diabetic patients (P< 0.05).
Conclusion: The findings of the research showed that high-intensity interval training after 12 weeks can cause a greater effect on inflammatory, pro-inflammatory and anti-inflammatory indicators compared to aerobic, combined and resistance training. But this is the resistance exercise that caused the reduction in inflammatory, pro-inflammatory indicators and increase in anti-inflammatory indicators in obese type 2 diabetic patients to be more permanent. Therefore, the effectiveness of resistance training in non-training conditions from three methods of high-intensity interval training, aerobic and combined (aerobic + resistance) has a greater effect on low-grade inflammation and results in a longer recovery in obese type 2 diabetic patients.
