Abstract
Background: Diabetes Mellitus is a heterogeneous group of different metabolic disorders that are characterized by chronic increase of blood glucose and proteins, lipids and carbohydrates metabolism disorder. The aim of this study was to investigate the effect of 8 weeks of aerobic exercise on metabolic factors, quality of life and mental health of women with type II diabetes. Materials and Methods: In this semi-experimental investigation, 18 women with type П diabetes referring to Arak Petroleum Company Clinic were selected and divided into two groups: aerobic (10 participants) and control (8 participants). Aerobic group performed selected exercises in 8 weeks (three 30-50 min sessions per week). In this investigation, we used metabolic factors (such as total cholesterol, triglycerides, HDL, VLDL, LDL, FBS, HbA1c and Insulin serum) and SF-36 quality of life (QOL) and GHQ mental health (MH) questionnaires. The level of significance was considered to be 95% (P<0/05). Results: There were significant differences between the means of pre-test and post-test measures of FBS, HbA1C, Insulin serum, QOL and MH in aerobic group. There were no significant differences between the means of pre-test and post-test measures of TC, HDL, LDL, VLDL and triglycerides in aerobic group and all factors in the control group (P<0/05). Conclusion: Aerobic exercise affects metabolic factors, QOL and MH in type П diabetic patients and it results in their improvement.

Abstract
Background: The aim of the present study was to determine the response of lung function indices to aerobic and anaerobic exercises in polluted air. Materials and Methods: In this quasi-experimental study, 20 healthy men were randomly divided into two equal groups experiment and control. The experiment group initially had one session of aerobic exercise and after a three-week break, received one session of anaerobic exercise on ergometer bicycle in polluted air. The control group did the same kind of exercise in healthy clean air. Lung function tests were run before, right after (the first post-test), and 24 hours after the exercises (the second post-test). Results: Aerobic exercise in unhealthy polluted air resulted in the significant reduction of FEV1, FVC, and FEF25-75% indices in the first and second post-tests. Following anaerobic exercises in polluted air, a significant decrease was observed in FVC and FEF25-75% indices in both the first and second post-tests. FEV1 and FEF25-75% indices in the first and second post-tests, and FEV1 and FVC indexes in the second post-tests underwent a remarkably greater reduction following aerobic exercise. Conclusion: While aerobic physical exercise in polluted air caused a reduction in the lung function indices (FEV1, FVC and FEF25-75%) in the first and second post-tests, it seemed that anaerobic exercises in polluted air induced a significantly smaller reduction in FEV1 and FEF25-75% in the first and second post tests, and FEV1/FVC in the second post test.

Abstract
Background: Exercise can counteract the negative effects of stress, but variations in exercise protocols and intensities have generated different results. The purpose of this study was to investigate the effect of immobilization stress on cognitive performance and the moderating role of exercise.
Materials and Methods: In this experimental study, adult Albino-Wistar rats were randomly assigned to 5 groups. The animals underwent immobilization stress (2 hours per day×7 day), exercise (30 minutes per day×7 day), or no intervention. The rats were trained and tested using Morris water maze.
Results: The control group had better performance than the stress group in acquisition (p<0.01) and recall (p<0.05) in Morris water maze. There was not a significant difference between exercise-stress and control groups in water maze performance. Stress increased corticosterone levels (p<0.001), but exercise had a significant effect on decrement of corticosteron levels (p<0.001). Also, despite the absence of a significant difference between sham and exercise groups in the acquisition stage, the exercise group had a better performance in the recall stage (p<0.05).
Conclusion: Immobilization stress can impair acquisition and mild exercise has a protective effect against stress-induced negative effects. Corticosterone may be a major mediator in the protective effect of exercise against stress-induced cognitive impairment. In addition, the role of exercise in retrieval of past experiences is more prominent than their acquisition.

Abstract
Background: Regarding the importance of prevention of cardiovascular disease during menopause the purpose of present study was evaluating the influence of eight weeks progressive aquatic exercise on serum Apoproteins of A and B and lipoproteins in obese and normal weight menopause women.
Materials and Methods: This was a semi-experimental study in which 29 menopause women from Isfahan (age: 57.4 ±4.68 years) voluntarily participated in it. According to body mass index (BMI), participants were divided to obese (n=15, BMI= 30.21 ±3.90) or normal weight (n=14, BMI=22.44 ±2.25) groups. Subjects of both groups participated in 8 weeks aquatic exercise, three times a week, by progressive intensity of 50 to 70% of maximal heart rate and duration of 45 minutes.
Results: Findings of study indicated a significant influence of exercise on VLDL, Apo A and B and ApoB/ApoA in in obese group. In normal weight group, exercise caused significant changes in LDL, VLDL, Apo A and B and ApoB/ApoA, but there was no significaut difference between groups in none of study variables.
Conclusion: According to our findings, progressive aquatic aerobic exercise induces similar reduction of some cardiovascular risk factors especially ApoB and ApoB/ApoA and increasing ApoA in obese and normal weight menopause women.

Abstract
Background: Chronic kidney disease as an important risk factor is associated with some disorders which are key causes of death and disability in older people. Therefore, the aim of this study was to assess the combined effect of regular aerobic exercise with garlic extract on renal apoptosis regulatory factors in aged rats with chronic kidney disease.
Materials and Methods: In this experimental research, 42 aged male Wistar rats(48-52 weeks) were selected and randomly divided into 6 groups: control, doxorubicin, doxorubicin-salin, doxorubicin- garlic, doxorubicin - exercise, doxorubicin –garlic-exercise(combined). Chronic kidney disease was induced by a single subcutaneous injection 8.5 mg/kg of doxorubicin. Swimming training was programmed 3 days /week, 30 min/day for 8 weeks. Both the doxorubicin garlic and combined groups with garlic extract were administered by garlic gavage at a dose of 2.5 g/kg. The renal Bax and Bcl-2 levels were evaluated by ELIZA method. A one-way analysis of variance was used to data analysis (p<0.05).
Results: The results showed that induced chronic kidney disease was associated with a significant increase on Bax and a decrease on Bcl-2 in aged rats. Also, 8 weeks swimming training, garlic supplementation and the combined intervention significantly reversed these changes. Furthermore, no significant difference have been observed in the effect of these interventions on Bax and Bcl-2 in aged rats with chronic kidney disease.
Conclusion: It seems that the use of non-pharmacological treatment methods such as exercise training, garlic extract supplement, and combination of the both interventions may be effective in reducing apoptosis resulted from chronic kidney disease in aged rats.

Abstract
Background: Sirtuin-1 regulates important cellular processes, including apoptosis, cellular senescence, and metabolism. Therefore, sirtuin-1 may be a novel therapeutic target for type 2 diabetes. The aim of this study was to investigate the effect of 8 weeks aerobic training on sirtuin-1 level and cardiometabolic parameters in women with type 2 diabetes.
Materials and Methods: In this semi-experimental study with pretest – posttest design, twenty diabetic women (aged 43.92±5.2 y) were randomly assigned to aerobic training or non-exercising control groups. Aerobic training program was performed 50-60 min/d, 3d/wk, for 2 months. Serum levels of sirtuin-1, body composition and metabolic parameters were assessed before and after the training period. Data were analyzed by paired T test.
Results: Adiposity indices, total cholesterol, triglyceride, LDL- cholesterol,blood glucose and insulin resistance index were significantly reduced in the intervention group compared to the control (p<0.05). Also, sirtuin-1 level was increased in the intervention group compared to the control (p<0.05).
Conclusion: These findings show that aerobic exercise is associated with an improvement in siruin-1 levels and metabolic indices in women with type 2 diabetes.

Abstract
Background: Diabetes mellitus is a common disease in human societies that dealing with its complications imposes enormous cost to the health system. The previous studies have shown that bone biochemical markers can be used for evaluation of bone metabolism in response to physical activity. The purpose of this study was to examine the effect of increasing 10-week aerobic exercise (AE) on serum osteocalcin, PTH and glycemic and anthropometric indices in postmenopausal women with type II diabetes.
Materials and Methods: In this semi-experimental study, 40 postmenopausal women with type II diabetes (40-60 years) as available subjects were selected and randomly assigned into two exercise (20) and control (20) groups. Exercise protocol was AE and walking activity for 10 weeks (3d/wk, 45 to 60 min/d with 45% to 60% HRRmax intensity). Blood samples were taken before and after exercise to measure serum variables. Data were analyzed by T-test and statistical significance criterion was set as p<0.05.
Results: AE makes a significant increase in osteocalcin levels and a decrease in insulin resistance index, insulin and fasting blood glucose in the experimental group (p<0.05). Changes in other variables such as PTH, HbA1c and anthropometric indices were not significant (p>0.05).
Conclusion: Due to the favorable effects of AE on osteocalcin and glycemic indices, it seems that this training method can be recommended as a non-invasive treatment for maintaining bone density and controlling blood glucose in diabetic patients.

Abstract
Background: IL-4 plays a key role in the pathogenesis of asthma and the increased serum level of that is positively correlated with asthma severity and obesity. IL-4 induces IgE secretion by B cells. Previous studies suggesting an anti-inflammatory effect of exercise training on asthmatic lungs. The aim of the present study was to investigate the effect of 12 weeks of aerobic exercise training on serum levels of IL-4 and IgE in overweight and obese asthmatic women.
Materials and Methods: 21 overweight and obese asthmatic women were selected and divided into two groups including experimental (n=12) and control (n=9) groups. The experimental group performed aerobic exercise training, three times a week, 60 minutes each session. Fasting blood samples were collected before and 2 days after completion of the course. The data were analyzed by using SPSS22 software
Results: A significant decrease in serum IL-4 (p = 0.015, t = - 2.68), BMI (p = 0.014, t = - 2.72) and weight (p = 0.001, t = -3.99) was shown following the 12 weeks of training in the experimental group compared to the control group. There were no significant correlations between the obesity changes and the Inflammatory Marker Changes (p>0.05).
Conclusion: The present study indicates that aerobic exercise training reduced the serum levels of IL-4 independent of obesity changes in overweight and obese asthmatic women.

Abstract
Background: H2S plays a key role in the pathogenesis of the Alzheimer’s disease. The aim of the present study was to investigate the effects of 4 weeks of the special aerobic training after induction of Alzheimer’s disease by Aβ1-42 injection on CBS and SAM levels in hippocampus of Wistar male rats.
Materials and Methods: Twenty male Wistar rats (8 weeks old and weight 195 ± 20 g) were divided into four groups including: healthy control, Alzheimer’s control, Alzheimer’s + training and sham. To induce Alzheimer’s disease, Aβ1-42 was infused into the hippocampus of rats. Training group trained for 4-week. For data analysis, one-way ANOVA was used and Eta and Omega squared tests were used to determine the effect size (p<0.05).
Results: Findings revealed that 4 weeks of special aerobic training increased significantly the CBS and SAM levels in hippocampus of Alzheimer’s rats compared to the control Alzheimer’s rats ( ES=53; p= 0.007, ES= 92.22; p= 0.001). Also, we showed 4 weeks of special aerobic training increased CBS level in hippocampus of Alzheimer’s rats compared to the healthy cotrol group (ES= 44.07;
p= 0.014).
Conclusion: It seems that the special aerobic training can be used as a useful non-pharmacologically effective therapeutic treatment for Alzheimer's patients through positive regulation of hydrogen sulfide via CBS and SAM enzymes.

Abstract
Background and Aim: Physical activity causes the releases of bone resorption indices in the bloodstream by the mechanical load on bone, which in interaction with adipokines reduces obesity and prevent its complications. So, the present study aims to compare the effects of aerobic and resistance exercise on Anthropometric Indices and osteocalcin, leptin, adiponectin levels in overweight men.
Materials and Methods: A total of 40 overweight young healthy men (BMI 28.67±0.96 and age 31.50 ± 2.23) were randomly assigned to control (n = 14), aerobic exercise (n = 13) and resistance exercise (n = 13) groups. Subjects in the exercise group were on 8-week supervised exercise training programme for three sessions per week (aerobic exercise were performed at 60-85% of HRR, and resistance exercise were performed at 55-75% of 1RM). Osteocalcin and adipocytokines (leptin, adiponectin) were assessed from fasting blood samples before and after the 8-week exercise programme. Data were analyzed by t-test and ANOVA.
Ethical Considerations: This study with research ethics code IR.IAU.RASHT.REC.1396.124 has been approved by research ethics committee at Islamic Azad University, Rasht branch, Iran and also has been registered with code IRCT20180226038876N1 at Iranian Registry of Clinical Trials (IRCT).
Findings: Aerobic and resistance training led to decrease in anthropometric indices (p<0.05), leptin levels (p<0.001, p=0.001) and increase in osteocalcin (p=0.001, p<0.001) and adiponectin (p=0.001, p<0.001), respectively. In addition, the difference between the two training groups was not statistically significant (p>0.05).
Conclusion: Considering to the effects of aerobic and resistance exercise on osteocalcin and adipocytokines level, it seems that both exercise methods can be increasing mechanical load on bone mass and cause to change in energy metabolism and body weight and can be an important factor in decrease of obesity complications.

Abstract
Introduction: Different training methods increase performance capabilities in addition to metabolic changes in body organs. The present study aimed to compare the effect of endurance and strength training on anthropometric indicators, glucose changes, fat metabolism, and irisin levels of young male students.
Methods: Thirty-six obese students (age: 21.19 ± 2.43 years; weight: 88.59 ± 6.20 kg; height: 175.41 ± 12.96 cm; body mass index: 30.45; fat percentage: 25.73%) were randomly placed in one of control, endurance, and strength training groups (n= 12). The strength training group trained for 8 week/3 session/4 sets/10 repetitions/ from 50 to 70% of the one repetition maximum (incremental manner, every 2 weeks), and the endurance training group trained for 30 minutes of aerobic jogging with 60 to 80% heart rate maximum. Plasma irisin, glucose, insulin, insulin resistance, fat percentage, body mass index, weight, waist circumference, and hip circumference were measured. The data were analyzed by one-way analysis of variance and Tukey's test at 0.05.
Results: Body weight (P = 0.03), fat percentage (P = 0.04), and body mass index (P = 0.04) significantly decreased in the post-test of endurance training group. Irisin level in the post-test in the control group had a significant difference with endurance and strength training (P = 0.01 and P = 0.02, respectively). Insulin in the post-test of the control group was significantly different from the endurance and strength group (P = 0.00 and P = 0.00, respectively). The level of insulin resistance in the post-test of the endurance and strength group had a significant difference compared to the control (P = 0.00 and P = 0.00, respectively).
Conclusions: Eight weeks of aerobic treadmill training and strength training with free weights can improve body composition, increase irisin levels, and reduce insulin resistance in obese male adolescents.
