Abstract
Background and Objective: Imbalance Between antioxidant defensive system and increased production of free radicals leads to oxidative stress that can be effective in making cellular damage and causing some diseases such as diabetes. The aim of the current study was to investigate the effect of eight-week purslane extract consumption on some peroxidant and antioxidants indicators in patients with type 2 diabetes.
Material and Methods: The Participants were 16 women with type 2 diabetes who had not the history of once a week regular physical activity program, in previous five years. They were randomly divided into two groups of experimental, purslane supplementation for eight weeks, and control. Blood sampling was performed in two stages.
Results: After eight weeks of purslane consumption, resting levels of MDA, SOD and CAT in Supplementation group showed a significant decrease compared to those of control group.
Conclusion: Purslane consumption can improve peroxidant/antioxidant balance in women with type2 diabetes.

Abstract
Abstract Background and Objective: The hormonal responses are different, according to type, intensity and the duration of training. We aimed to compare the effect of endurance and resistance training in untrained men on the level sexual hormone including testosterone, estradiol, and on sex hormone binding globulin (SHBG). Material and Methods: this study was conducted on male Student Volunteers divided randomly into three groups of eight members, including endurance, resistance and control. To measure the variables, we performed sampling before and after the training program. Results: the levels of testosterone and estradiol, in both groups have a significant (p<0.05) increase and decrease respectively. SHBG level was significantly increased only in endurance group (p<0.05), But LH level was meaningfully increased only in the resistance group (p<0.05). Conclusion: The endurance and resistance training can increase the production of testosterone .Increased testosterone and decreased estradiol in men lead to sperm production and improve fertility. Keywords: Endurance training, Resistance Training, Testosterone, Estradiol

Abstract
ABSTRACT
Background and Objective: Exercise training and supplementation have different effects on the immune system. The aim of the present study was to evaluate the effect of ginger supplementation and endurance training on serum levels of Interleukin 1 alpha (IL1α) and tumour necrosis factor α (TNFα) in untrained young women.
Methods: The study was performed on 32 untrained young women with mean age of 30±2 years from city of Abbas Abad, in 2014. The participants were randomly assigned into four groups of endurance training (E), endurance training and ginger supplementation (EG), ginger supplementation (G) and control (C). Endurance training was performed at 60-70% heart rate reserve for six weeks, three times a week, and for 60 minutes per session. Daily supplementation with 10 mg/Kg/day of ginger extract was carried out. T-test and ANOVA were used to evaluate the effect of independent variables, and make comparisons between the groups.
Results: The mean level of IL-1α decreased significantly after the training period in the G and EG groups. There were significant differences between E and EG groups and EG and C groups. The results of intergroup comparison showed that the mean levels of TNFα decreased significantly after the training in the E, G and EG groups. There were significant differences between E and EG groups, E and G groups, EG and C groups, and G and C groups.
Conclusion: Ginger consumption and adaptation to endurance training can counteract the negative effects on immune function and stability of mast cell membrane.
Keywords: Endurance Training, Ginger, IL-1alpha and TNF-alpha.

Abstract
ABSTRACT
Background and objectives: Nonalcoholic fatty liver disease (NAFLD) is a chronic hepatic disease characterized by fat accumulation inside hepatocytes. The aim of this study was to evaluate effects of exercise training and resveratrol supplementation on activin A and follistatin levels in rats with NAFLD under a high-fat diet.
Methods: Fifty-six old (40-50 weeks) male Wistar rats were assigned to a healthy control group and seven experimental NAFLD groups: 1. high-fat diet, 2. saline, 3. resveratrol supplementation, 4. continuous exercise, 5. interval exercise, 6. continuous exercise+ resveratrol supplementation and 7. interval exercise+ resveratrol supplementation. Rats in the resveratrol supplementation groups were given 25 mg/kg of body weight intraperitoneal injection of resveratrol daily. Exercises were performed five days a week for eight weeks. Data were analyzed with SPSS (version 21) using one-way analysis of variance (ANOVA) and Tukey's post hoc test at significance of 0.05.
Results: Exercise training and resveratrol supplementation significantly decreased plasma activin A level and increased activin A expression (P<0.05). Plasma level of follistatin was significantly higher in rats under a high-fat diet compared to healthy control animals. All exercise and supplementation groups alone and combined lowered follistatin levels. However, follistatin mRNA expression increased significantly after resveratrol supplementation alone, continuous exercise+ resveratrol supplementation, and interval exercise+ resveratrol supplementation.
Conclusion: Resveratrol has a beneficial effect on activin A and follistatin levels in rats with NAFLD. In addition, resveratrol supplementation combined with exercise training may have greater health benefits for NAFLD patients compared to resveratrol supplementation or exercise training alone.

Abstract
Background and objectives: Cardiac apoptosis is one of the most important cardiovascular complications of diabetes. We aimed to investigate the changes of Bax, Bcl2 and caspase 3 in cardiac tissue of diabetic rats after six weeks aerobic exercise.
Methods: Thirty two male Wistar rats were randomly divided into healthy control, diabetes control and diabetes + exercise groups. Diabetes was induced by intraperitoneal injection of streptozotocin solution (55 mg/kg). Two weeks after the injection, fasting blood glucose levels were measured to confirm induction of diabetes. The exercise program was performed five days a week for six weeks. Variables were evaluated by ELISA and western blot analysis. All statistical analyses were performed in SPSS (version 22) using ANOVA and at significance of 0.05.
Results: The induction of diabetes in the control groups resulted in a significant increase in Bax, Bax/Bcl2 ratio and a significant decrease in Bcl2 levels (P=0.024). The six-week training exercise in diabetic groups significantly decreased Bax and Bax/Bcl2 ratio and significantly increased Bcl2 (P=0.018).
Conclusion: Our finding showed that diabetes could increase apoptosis in cardiac tissue. In addition, the six-week aerobic exercise can be used as a non-pharmacological strategy to reduce diabetes-related apoptosis in cardiomyocytes.

Abstract
Background and objectives: Sedentary life style and high-fat diet are one of the key causes of coronary artery disease. The aim of this study was to evaluate effects of periodic exercise and consumption of fenugreek seed extract on the expression of oxidized low-density lipoprotein (oxLDL) and reactive oxygen species (ROS) genes in patients with coronary artery occlusion.
Methods: The present quasi-experimental study was performed on 32 men (60±5 years) with coronary artery disease. The subjects were randomly divided into four groups: control, exercise, fenugreek supplementation, and combination of exercise and fenugreek supplementation. The training program consisted of eight weeks of intermittent running at 55 to 65% heart rate reserve, three sessions per week, with an emphasis on gradual overload. The subjects consumed 10 mg/kg of body weight fenugreek extract daily. Data analysis was performed using two-way analysis of variance and Tukey's test at statistical significance of 0.05.
Results: The mean expression ratio of oxLDL and ROS genes in the intervention groups decreased significantly (p<0.0001). Compared with the control group, the most profound decreased in oxLDL and ROS expression occurred after combination of exercise and fenugreek supplementation (p<0.0001).
Conclusion: The results showed that intermittent exercise and consumption of fenugreek seed extract might have beneficial effects on the antioxidant defense system in patients with coronary artery occlusion.

Abstract
Background: Significant economic consequences can lead to various problems and complications, including medical complications. Coronary artery disease (CAD), a serious health threat with increasing prevalence, is a major cause of death and mortality worldwide. This study aimed to investigate the effects of a special training program on cytochrome P450 (CYP) gene expression and reactive oxygen species (ROS) levels in patients with coronary artery bypass surgery.
Methods: This semi-experimental study was conducted on 16 patients who underwent coronary artery surgery in Babol City, Iran. The patients were selected using a random sampling method and divided into 2 groups: experimental and control groups. The experimental group engaged in an exercise program consisting of 3 sessions per week for a duration of 8 weeks. The expression levels of CYP and ROS genes were measured by the real-time polymerase chain reaction (PCR) method. The analysis was performed by comparing covariances and means.
Results: ROS gene expression levels significantly decreased in the experimental group than in the control group (P=0.003). However, there was no significant difference in P450 levels between the experimental and control groups (P=0.99).
Conclusion: Special exercises reduced ROS expression and increased P450 expression in patients who had coronary bypass surgery. There is a probability that special exercises, can effectively prevent heart damage by increasing antioxidant capacity and reducing ROS.

Abstract
Background: Cardiovascular diseases, especially coronary artery problems, are the main causes of death. The aim of this study was to evaluate the expression of NOs and NOX2 in coronary artery patients after aerobic exercise and omega-3 intake.
Methods: The present study was a quasi-experimental study in which 32 men with coronary artery disease in the age range of 55 to 65 years were selected and randomly divided into 4 groups: control, exercise, omega-3, and omega-3 + exercise. The training program consisted of 8 weeks of intermittent running training, 3 sessions per week, with an intensity of 55 to 65% of the subjects' heart rate reserve and with an emphasis on gradual overload. Subjects consumed 1000 mg of omega-3 daily.
Results: There was a significant increase (P <0.0001) in the mean expression of the NOS gene in the exercise + omega-3 group compared to the control group. The mean ratio of NOX gene expression changes in the exercise group, omega-3, and the combination of exercise + omega-3 was significantly reduced compared to the control group (P <0.0001).
Conclusion: According to the results of the present study, the ability of exercise and omega-3 supplementation to reduce the level of oxidant stress and increase homeostasis control in coronary artery insufficiency shows an important molecular mechanism that underlies the benefits of these interventions.
