Therefore, the aim of the current research was the effect of aerobic exercise on the level of brain-derived nerve growth factor (BDNF) and interleukin-6 (IL-6) in the serum of obese middle-aged men. For this purpose, 20 obese middle-aged men (35-45 years old and BMI>30) were randomly assigned to two groups of aerobic training and control. Aerobic training was performed 3 sessions a week with an intensity of 80% of the reserve heart rate and 30 minutes in each session. Serum BDNF and IL-6 levels were measured by ELISA method. Paired t-test and independent t-test were used for intra-group and inter-group comparisons. The results showed that BMI, PBF and IL-6 level were significantly lower in the post-test of the aerobic training group compared to the pre-test (p<0.05). The level of BDNF increased in the post-test of the aerobic group compared to the pre-test, but it was not statistically significant (p=0.093). Overall, these results show the positive effects of aerobic exercise on BMI, PBF and serum IL-6 levels in obese middle-aged men, but despite the increase in serum BDNF levels in these subjects, this increase was not statistically significant. It seems that traininf intensity was not sufficient to increase BDNF level in line with improvement of systemic inflammation. Manuscript profile -

This study was a Quasi-experimental design by using pre-test and post-test. 91 participants randomly allocated into two groups and samples were students of Islamic Azad University of Gorgan branch with body mass index classes above 30 kg/m2. Instruments of study included blood collection devices (cotton, alcohol, syringe, test tube) and digital scales and laboratory biochemistry equipment to examine blood. Independent t-test was used to analyze the data. Findings of the study have shown that 6 weeks of intensive periodic interval exercise had no effect on triglyceride levels, total cholesterol and systolic and diastolic blood pressure in obese men. Also, 6 weeks of intensive periodic interval exercise had no effect on high-density lipoprotein in obese men, but in low-density lipoprotein had observed a significant difference. Low-intensity aerobic exercise such as walking has an important role in controlling systolic and diastolic blood pressure. Regular physical activity has effect in increment high-density lipoprotein and also had a protective role in the heart. Also, population with low-density lipoprotein can use intensive exercise with 55% maximum heart rate for 30 minutes in day and 5 days per week to maintain health. Manuscript profile -

5 - The Effect of Combined Exercise and Broccoli Supplementation on FGF-21 and Insulin Resistance in Type-2 Diabetes Obese Men

The present study was aimed at examining the effect of broccoli powder supplementation with combined exercise training on FGF-21 and insulin resistance in type 2 diabetes men. This experimental design was conducted with pre-test and post-test and four groups. To this end, 44 volunteer diabetic men after homogenization based on individual characteristics were randomly assigned to four groups of 11 individuals including exercise-supplement group, exercise-placebo group (exercise), control-supplement group (supplement), and control-placebo (controls). Combined exercise program included 12 weeks, three sessions per week. Moreover, broccoli supplement was 10 grams per day for 12 weeks. The blood sample was taken 48 hours before and 48 hours after the last training session and used for analysis. Analysis of intergroup indicators revealed a significant difference between the groups in FGF-21 (p = 0.017) and insulin resistance (p = 0.01). Significant changes in the measured indices were also observed in the intragroup changes (p < 0.05). The results of this study showed that 12 weeks of combined exercise with broccoli supplement significantly reduced FGF-21, blood glucose, and insulin resistance in all three groups of exercise- supplement, exercise, and supplement. Therefore, incorporating broccoli into the diet can partially prevent the risky effects of type 2 diabetes. Manuscript profile -

The aim of this study was to investigate the effect of various resistance training (traditional, circuit and Interval) on BDNF and SPARC in obese men.For this purpose, 44 obese male volunteers after homogenization were randomly divided into 4 groups based on individual characteristics: control (n = 11), traditional (n = 11), Circuit (n = 11) and Interval (n = 11). Subjects performed three sessions of resistance training each week for 12 weeks. Blood samples were taken before first training session and 48 hours after the last training session and were used to analyze the factors. Examination of intergroup differences for BDNF and SPARC showed that there was a significant difference between groups (p < 0.001). The results of Bonferroni test for BDNF showed that there was a significant difference between control with interval (p < 0.001) and circuit (p < 0.001) and traditional (p = 0.012) groups. Also, the study of intragroup changes showed that BDNF values were significantly increased in the traditional training groups (p = 0.008), the circuit resistance training group (p < 0.001) and the interval training group (p < 0.001). The results of Bonferroni test for SPARC showed that there was a significant difference between control with interval (p < 0.001) and Circuit (p < 0.001) groups. Also, the study of intragroup changes showed that SPARC values were significantly reduced in the traditional training groups (p < 0.001), the interval training group (p < 0.001) and the circuit training group (p < 0.001). In the present study, it was shown that 12 weeks of traditional, circuit and interval resistance training, increased plasma BDNF levels and decreased SPARC plasma levels in obese men. It should be noted that the desired changes in circuit and interval resistance training protocols were better than the traditional type. Manuscript profile
