Aim: choosing the type of sports activity for better effect in obese people can be considered as an important factor and challenge. On the other hand, Spexin plays a central and peripheral role in regulating satiety and food intake, motility of the digestive tract, energy metabolism and glucose/lipid metabolism. Therefore, the present study was conducted with the aim of comparing the effect of eight weeks of aerobic exercise and 30-20-10 on serum levels of spexin and lipid profile indices of obese men. Methods: The present experimental study and its statistical sample were 30 obese men who were randomly assigned to two groups of aerobic exercise and 30-20-10 exercise (15 people in each group). Aerobic exercise and 30-20-10 exercise were performed for eight consecutive weeks. Before and after the start of the protocol, height, weight, maximum oxygen consumption blood sampling from the brachial vein were performed to evaluate the amount of spexin and lipid profile.Results: The inter-group results showed that there was a significant difference in the levels of SPX and total cholesterol between the two groups of aerobic exercise and 30-20-10 exercise, so that by examining the difference in means, the greatest effect was after aerobic exercise. P = 0.001 and P = 0.005). But HDL levels were not significantly different between the two groups (P=215).Conclusion: According to the results of the present study, it is likely that aerobic exercise has a better effect on the serum levels of spexin and cholesterol in obese people than 10-20-30 exercises.

Aim: Changes in the hypothalamo-pituitary axis are probably related to changes in sex hormones. Physical training is one of the effective factors in the changes of this axis. purpose of this study was the effect of six weeks of ResistanceTraining on free Testosterone serum levels, sex hormones binding globuline, Inhibin b and luteinizing and follicle-stimulating hormone in obese men students. Methods: For this purpose, 20 obese male students with aged range of 20 ± 2 years participated in this study and divided randomly into 2 groups 10 people of resistance training and control. Resistance training was performed for six weeks and three sessions per week in %60 to %70 repetition maximun. In order to analyze the biochemical variables, blood samples were taken at two stages, 48 hours before and after of training period. Inter group and between changes of information were performed by dependent and independent t-test. Results: The results of this study showed that resistance training led to a significant increase in free testosterone serum concentration and a significant increase in SHBG in obese men. But after six weeks of training, there were no significant changes in inhibin b, luteinizing hormone and follicular stimulation hormone. Conclusion: six weeks of resistance training with improved body composition, upper and lower body muscle strength and also aerobic power are associated with changes in sex hormones in obese men.

Abstract
Aim: Appetite is a subjective concept to describe control of food intake, and is under control of brain and hormones like active ghrelin. Ever-increasing incidence of obesity and related multiple psychological and physiological problems converted it into a global epidemic, while sedentariness is considered as one of the main obesity-causing factors. Chemerin is a new adipokine that its serum level increases in obese patients. The purpose of this study was to survey effect of twelve weeks aerobic training on chemerin, active ghrelin, and appetite in sedentary obese men.
Method: In a semi-experimental study, twentyone sedentary obese men were randomly placed in two groups: aerobic training (n=10, 27.8±3.2 yr, 93.5±7.1 kg, 31.7±3.4%, 32.0±3.5 kg/m2) and control group (n=11, 26.7±2.6 yr, 92.9±6.3 kg, 31.4±3.2 %, 32.3±2.8 kg/m2). General characteristics of subjects, circulating levels of chamerin and ghrelin (using ELISA kits), and appetite (using Council on Nutrition Appetite Questionnaire) were assessed before and after training. Aerobic training protocol consisted of twelve weeks pedaling on cycle ergometer (3 sessions per week, intensity 60-70% of reserved heart rate, duration of each session 20-40 min). Data analyzed by SPSS16 software. Statistical significance was accepted at P
