Abstract
Background: Fetoin-A and -B are hepatokines that are related to type 2 diabetes. The aim of the present study was to investigate the effect of a period of resistance and endurance training with Ursolic acid consumption on the levels of Fetoin-A and -B in the liver tissue of elderly diabetics.
Methods: Fifty six 21-month-old male diabetic rats were randomly divided into seven equal groups of control (C), Ursolic acid supplement (UA), supplement+resistance exercise (UA+R), supplement+endurance exercise (UA+E), Resistance training (R), endurance training (E) and sham group (D). Resistance training protocol with intensity of 60% MVCC, 14-20 times of ladder climbing with one minute rest between each effort and endurance training including running on Treadmill at high intensity 60-75% and low intensity 30-40% of maximum speed for five days per week for eight weeks. Supplemented groups received 500 mg/kg UA in combination with a high-fat meal.
Results: Fetoin-A level was significantly decreased in UA, E, UA+E groups (p≤0.05) and only in R and UA+R groups, there was no significant decrease. Also, The amount of Fetoin-B in diabetic rats in the UA, E, R, UA+E groups decreased significantly (p≤0.05) and only in the UA+R training group there were no significant changes. The amount of Fetoin-A and Fetoin-B was significantly different between E and R and UA+R and UA+E groups (p≤0.05), which the largest decrease was in the UA+E group.
Conclusion: Considering the beneficial effects of exercise training as well as UA supplementation on hepatokines, it seems that the simultaneous application of two interventions of exercise training and UA supplementation has a more therapeutic effect on the hepatic hepatokines of diabetics.

Abstract
Background: Leptin and adiponectin are adipokines produced by fat cells and play an important role in obesity. The purpose of this study was to compare the effect of low-calorie diet (LCD) and exercise (Exe) on leptin and adiponectin in middle-aged and elderly adults with overweight and obesity.
Methods: A systematic search was conducted in PubMed, Web of Science, SID, Magiran, and Google scholar databases for English and Persian articles published until August 2023. The effect size and 95% confidence interval (CI) were calculated using the random effect model.
Results: The results of 25 studies with 2063 middle-aged and elderly people with overweight and obesity showed that the combination of exercise and diet compared to exercise alone causes a significant decrease in serum leptin [SMD=-0.4, P=0.001], and a significant increase in serum adiponectin [SMD=0.17, P=0.02] in middle-aged and elderly adults with overweight and obesity. Also, findings showed that the diet compared to exercise alone causes a decrease in serum leptin [SMD=-0.16, P=0.1], and a significant increase in serum adiponectin [SMD=0.05, P=0.7] in middle-aged and elderly adults with overweight and obesity. Also, diet compared to exercise alone does not cause a significant change in serum leptin [SMD=-0.11, P=0.2], and serum adiponectin [SMD=0.02, P=0.8] in middle-aged and elderly adults with overweight and obesity. Conclusion: It is suggested that middle-aged and elderly people to achieve hypoleptinemia and hyperadiponectinemia, use a combination Include exercise training and low-calorie diet in your lifestyle.

Abstract
Background: This review aims to investigate and analyze recent studies related to the effects of various exercise training on adipokines secreted from adipose tissue in patients with type 2 diabetes.
Methods: Search in Persian and Latin databases PubMed, ScienceDirect, Google Scholar, Magiran, and SID with the keywords aerobic exercise, resistance training, High-intensity interval training, diabetes, Adipokine, Leptin, Adiponectin, and Resistin, resistance training, intense interval training, aerobic exercise, combined exercise, adipokine, leptin, adiponectin and resistin were performed to retrieve articles published in the period from 2010 to 2023.
Results: The results obtained from the study showed that aerobic exercise with moderate intensity (60 to 80%) reduces the leptin levels of diabetic patients, however, the effect of combined exercises (aerobic and resistance) is much greater than other types of exercises. In addition, aerobic exercises with moderate intensity (50 to 70%) lead to an increase in adiponectin levels in diabetic patients, however, high-intensity interval training (HIIT) had a greater effect in increasing adiponectin levels than other exercises. Also, studies showed that all three types of activities, aerobic exercise (50-70% intensity), intense intermittent exercise, and resistance exercise (30-70% 1RM) have the same effects in reducing the resistance levels of diabetic patients.
Conclusion: Aerobic exercises with medium and high intensity and especially combined exercises (aerobic and resistance) while improving adipokines, decreasing leptin and resistin levels, and also increasing adiponectin in diabetic patients.

Abstract
Background: The aim of this study was to investigate the effect of eight weeks of circuit resistance training and saffron supplement on visfatin serum levels and insulin resistance in overweight men.
Methods: In this semi-experimental study, 40 obese and overweight students were randomly divided into 4 groups: exercise, exercise+supplement, supplement and control (10 people in each group). The exercise groups performed circular resistance exercises for eight weeks and three sessions each week for 90 minutes in the evening. The supplement and exercise+supplement groups used saffron tablets with a dose of 30 mg per day as a supplement. Blood samples were collected in two phases of the pre-test and 48 hours after the last training session. The data were analyzed using covariance and paired t test at a significant level of P≤0.05.
Results: Correlated t results showed a significant decrease in visfatin and insulin resistance in the post-test of the training, training+supplement and supplement groups compared to the pre-test (P<0.05). The results of the analysis of covariance showed that visfatin increased and the insulin resistance index decreased significantly in the exercise, exercise+supplement and supplement groups compared to the control group (P<0.05).
Conclusion: It seems that eight weeks of circuit resistance training and the addition of saffron help on visfatin serum levels and insulin resistance can lead to the reduction of these two variables in overweight men. The saffron plant can play a protective role due to the presence of flavonoids and by stimulating the secretion of Visfatin.

Abstract
Background: Diabetes is a global epidemic and the most common metabolic disorder caused by impaired insulin secretion and glucose metabolism. The aim of this study was to investigate the effect of 8 weeks of aerobic training on serum levels of asprosin and insulin resistance index in diabetic rats.
Methods: The statistical population of this research included 40 10-week-old mice with an initial weight of 250 ± 20 grams, which were randomly divided into four groups (10 mice in each group): diabetic-exercise group (DT), diabetic group - Control (DC), healthy-training group (HT) and healthy-control group (HC) were divided. The program of aerobic exercises was performed for 8 weeks (5 sessions per week) in the form of running on a treadmill. Independent t-test and one-way analysis of variance (ANOVA) with Tukey's post hoc test were used to compare the groups. All data were analyzed at a significance level of 0.05 using SPSS-25 software.
Results: The results of the present study showed that streptozotocin injection induced diabetes in mice (P= 0.001). Induction of diabetes caused a significant increase in the serum levels of asprosin and insulin resistance in mice (P= 0.048 and P= 0.012, respectively). Eight weeks of aerobic training decreased the serum levels of asprosin and decreased insulin resistance in diabetic rats (P= 0.001 and P= 0.036, respectively).
Conclusion: Induced diabetes causes insulin resistance and increase in serum levels of asprosine, which can be improved by performing aerobic exercises.

Abstract
Background: Type 1 diabetes is characterized by persistent hyperglycemia and leads to impaired protein synthesis and ultimately muscle breakdown and reduction in muscle function. Therefore, this research was conducted with the aim of investigating the effect of moderate intensity continuous training (MICT) on the amount of 4EBP1 in the biceps muscle of type 1 diabetic rats.
Methods: The present study is of experimental-fundamental type in which 12 2-month-old male Sprague Dawley rats with an average weight of 280±30 grams participated. To induce type 1 diabetes, streptozotocin (STZ) solution was injected intraperitoneally at a dose of 65 mg/kg. 3 days after injection, blood sugar above 300 mg/dl was considered as an indicator of type 1 diabetes. After the induction of diabetes, the rats were randomly divided into 2 diabetic training groups (6 heads) and diabetic control groups (6 heads). The continuous training program (32 minutes with an intensity of 50-70% of maximum speed) was 8 weeks and 3 sessions every week. Data analysis was done through independent t-tests. Data analysis was done using GraphPad Prism software version 10.2.2. The significance level of the present study was considered P≤0.05.
Results: In the training group after 8 weeks of MICT, the intracellular content of phosphorylated (P=0.0001), total (P=0.0001) and the ratio of phosphorylated to total (P=0.002) protein 4EBP1 showed a significant change compared to the control group in the twin muscle tissue.
Conclusion: 4EBP1 protein seems to increase through 8 weeks of MICT and this mechanism can increase muscle synthesis in muscle tissue.

Abstract
Background: Clinical studies have demonstrated that diabetes, as a metabolic disorder, can significantly impact the quality of life of individuals affected by the condition. Physical activity has been identified as a potentially effective therapeutic intervention for managing diabetes in these individuals. This study examined the correlation between serum levels of GLP-1 and the hormones thyroxine, TSH, insulin, glucose, HbA1c, VO2peak, as well as various anthropometric indicators after eight weeks of calisthenics exercises.
Methods: This semi-experimental study involved 14 sedentary children with type 1 diabetes, averaging 12.42±1.28 years, selected through non-random sampling. The participants performed calisthenics exercises for eight weeks (three sessions per week). Physiological assessments and blood samples were collected 48 hours before and after the training period. The relationship was analyzed using Pearson's correlation test, and intra-group changes were assessed using paired t-tests.
Results: The findings demonstrated a positive and significant correlation between GLP-1 and insulin both before (r=0.703, p=0.005) and after the exercise intervention (r=0.668, p=0.009). Additionally, an inverse and significant correlation was observed between GLP-1 and waist circumference (WC) levels before (r=0.633, p=0.019) and after exercise (r=0.575, p=0.043), as well as between GLP-1 and body fat percentage after exercise (r=0.676, p=0.007). In terms of intra-group changes, the results indicated a significant increase in GLP-1, insulin, and VO2peak, along with a significant decrease in WC.
Conclusion: The findings of this study show that engaging in calisthenics exercises can be effective in reducing the negative effects of type 1 diabetes and increasing the health of diabetic children.

Abstract
Background: Diabetes can disrupt the balance of cell death through different cell pathways, and exercise or consumption supplements can be effective in maintaining the balance of cell death types; Therefore, the purpose of this research is the effect of magnesium supplementation and exercise training on the content of CREB2 and C/EBP homologous protein (CHOP) in the left ventricle of the heart of type 2 diabetic rats.
Methods: In this experimental study, 24 2-month-old male Sprague-Dawley rats with an average weight of 280±20 grams were selected. Type 2 diabetes was induced by injecting nicotinamide and streptozotocin solutions. The rats were randomly divided into 4 groups, 1) control, 2) supplement, 3) training and 4) training+supplement; Resistance training consisted of 8 weeks and 3 weekly sessions of climbing a ladder. Magnesium supplement was given to rats once a day. To analyze the data, one-way ANOVA and Tukey's post hoc tests were used in SPSS version 29.
Results: Eight weeks of magnesium supplementation and resistance training led to a significant change in the content of CREB2 and CHOP proteins between groups in the left ventricle of the heart (p=0.001). A significant decrease was observed in the groups of resistance training + magnesium supplement and magnesium supplement compared to the control group (p≥0.05); But the resistance training group had increased compared to the control group (p≥0.05).
Conclusion: The increase and decrease of CREB2 and CHOP proteins in the left ventricle of the heart can lead to improvement and physiological adaptation, like a bilateral mechanism.

Abstract
Background: Physical activity and green tea is one of the recommended ways to control obesity and its complications such as cardiovascular diseases, diabetes and liver inflammation. The aim of this study was the combined effect of exercise training and green tea on lipid profile in adults with overweight and obesity.
Methods: A systematic search of English and Persian articles published in PubMed, Web of Science, Scopus, SID, Civilica, and Magiran databases was conducted until June 2024.
Results: A total of 14 studies with 390 adults with overweight and obesity, of which 198 subjects were in the combined exercise and green tea group with an average age of 34 years old and BMI with an average of 30 kg.m2, of which 192 subjects in the control group with an average age of 34 years old and BMI with an average of 31 kg.m2 entered the present meta-analysis. The results showed that the combination of exercise training and green tea caused a significant decrease in TC [WMD=-22.923 mg/dl, P=0.001], TG [WMD=-9.946 mg/dl, P=0.001], LDL [WMD=-11.675 mg/dl, P=0.001] and insignificant increase HDL [WMD=8.888 mg/dl, P=0.017] in adults with overweight and obesity, compared to the control group.
Conclusion: The results of this meta-analysis showed that the combination of exercise training and green tea in overweight and obese adults decreases TC, TG, LDL and increases HDL. Therefore, exercise and green tea can be suggested to them as a non-medicinal and practical solution to improve lipid profile and reduce cardiovascular diseases, diabetes and liver inflammation.

Abstract
Background: Obesity is a disease whose incidence and burden on societies around the world is increasing. Sexual performance in these patients is an important aspect that is often ignored. Therefore, the aim of the present study was to investigate the effect of a period of exercise along with electrical stimulation on the gene expression of some sex markers in testicular tissue of fasted obese rats.
Methods: In this experimental study, with a control group of 40 male rats after induction of obesity and weight gain, randomly divided into 5 groups: control, fasting-obese, fasting-endurance exercise, fasting-electrical stimulation and Fasting-endurance training-electrical stimulation were divided. Intervention groups for a period of 4 weeks under endurance sports activity (with a speed of 10 to 20 m/min and duration of 20 to 40 minutes), electrical stimulation (foot shock device for 0.5 mA and 20 minutes) and fasting were placed. After exercise and anesthesia, brain tissue was done and after molecular processes, gene expression was measured using Real time-PCR machine.
Results: The results showed that training led to a significant increase in the expression of 5-alpha reductase and aromatase genes in samples compared to the fasted obese group (P=0.0001). Also, electrical stimulation and its combination with endurance training showed a significant increase in the 5-alpha reductase gene (P=0.0001).
Conclusion: It seems that endurance training and combined electrical stimulation of both during fasting by increasing the expression of 5-alpha reductase and aromatase genes in obese samples are effective in their sexual health and lead to its improvement.

Abstract
Background: This study aimed to compare the effects of high-intensity interval games and high intensity interval training on body composition indicators, aerobic capacity and lipid profiles of obese and overweight girls aged 10 to 12 years.
Methods: In this semi-experimental research, 30 girls (average height 149.26 ± 5.32 m, weight 67.41 ± 7.65 kg, and body mass index 30.14 ± 2.3 kg/m2) with overweight and obesity participated and were randomly divided into the groups of high intensity interval training (10), high intensity interval game (10) and the control (10). Training programs for eight weeks(3d/w), (90-85% of maximum heart rate) and 3-minute recovery (65-75% of maximum heart rate) with 4 times Repetition was done, which was done in the form of running in high intensity interval training and in the form of playing in high intensity interval game. Blood samples were taken to measure the serum levels of lipid profiles (48 hours before and after the intervention period).
Results: The two training groups compared to the control group, increased aerobic capacity and HDL and body fat percentage, TG, TC and LDL (P < 0.010) showed a significant decrease and between the two training groups in TG, LDL and HDL (P<0.01) was a significant difference, with a greater increase in HDL and a greater decrease in TG and LDL was accompanied in the high intensity game group.
Conclusion: High intensity interval games can be suggested as a more suitable solution to improve the lipid profile of obese and overweight girls.
