Aim: Changes in adipokines levels play an important role in the development of different disorders including the type 2 diabetes, which among them, chemerin and omentin-1 attracted a lotof attention. In contrast, positive effect of exercise training and vitaminD consumption have been reported in combating with pathologic effects of type 2 diabetes. The aim of present study is to determine the effect of eight weeks resistance training along withvitaminD consumption on levels of chemerin and omentin-1 in type 2 diabetic patientsMethod: 40 diabetics men with average age of 47.19±3.83 years old and body fat percentage 30.96±2.49 assigned in four groups including the placebo, vitaminD, training and training+ vitaminD groups. The resistance training program conducted for eight weeks and three session per week with 60 to 70 percent of 1RM intensity. VitaminD consumption considered daily 2000 iu and placebo (oral paraffin) ingestion considered in the same amount. At the baseline and ending intervention, blood samples collected and the levels of chemerin and omentin-1 were measured and insulin resistance calculated. Data were analyzed by analysis of covariance test and Bonferroni post-hoc test.Results: The present study findings indicated that in training and training+vitaminD groups the chemerin levels significantly decreased and omentin-1 significantly increased (p<0.05). Moreover, significant decrease of insulin resistance was observed in training and training+vitaminD groups (p<0.05).Conclusion: VitaminD ingestion can increase the hypoglycemic effects of resistance training partly, which these positive effects of resistance training and vitaminD consumption exerted by increase in omentin1 levels and decrease of chemerin levels.

Aim: Adipokines are molecules secreted from adipose tissue that are related to insulin resistance, metabolic syndrome, diabetes and cardiovascular diseases. Therefore, the effect of 8 weeks of resistance training along with green tea extract (GTE) supplementation on the concentration of adipokines apelin and chemerin in obese women was investigated.Method: Thirty untrained women with a body mass index (BMI) above 30 kg/m2 were selected from among obese women using a randomized, double-blind, placebo-controlled design method and were divided into three groups including training and green tea extract (GT), training and placebo consumption (PT) and green tea extract consumption (G). GT and G groups took 600 mg.kg-1 of GTE daily and PT group also took 600 mg of placebo for 8 weeks. The resistance training program consisted of 3 sessions per week for 8 weeks (60-70 minutes with an intensity of 65% to 80% of a one repetition maximum). Serum level of adipokines was measured using ELISA method.Results: The results of ANOVA with repeated measures indicate a significant decrease in serum levels of apelin and chemerin in GT and PT groups compared to G. Also, a significant decrease in the level of these adipokines was observed in the post-test compared to the pre-test in all three groups. Conclusion: 8 weeks of GTE intake and resistance training decreased inflammatory adipokines in obese women, and the combinatory effect of resistance training with GTE was more effective than the other two conditions.

Aim: The aim of this study was to investigate the effects of aerobic training on serum Chemerin levels, inflammatory and cardio-metabolic risk factors in factors in midlife males complicated with metabolic syndrome.
Method: twenty six males with local Met criteria (age: 54.69±3.67 yrs., BMI: 31.21±1.23 kg/m2 and Vo2peak: 20.38±4.49 ml/kg.min) were randomly divided into aerobic training (n=14) and control (n=12) groups. Throughout eight weeks of training (3 sessions /week) the training load were increased from 15-20 min at 50-55% of HRpeak (end GXT heart rate) to 35-40 min at 60-65%. Blood samples were collected at baseline and 48 h after the intervention.
Results: Aerobic training induced significant reductions in all (except for HDL and Vo2peak) the investigated variables (P<0.05). At baseline, body weight and age were recognized as the most important predictors of serum Chemerin (P<0.05). Throughout the intervention period, the changes in blood glucose and CRP were the significant predictors of the concomitant changes in serum Chemerin levels (P<0.01), and the changes of Chemerin were the only predictor of the accompanying changes in CRP level (P<0.03). Conclusion: Chemerin reduces synchronously with the beneficial effects on metabolic and inflammatory indices as well as aerobic fitness level to be likely as the results from blood glucose and CRP modifications induced by aerobic training. However; more research remains to be done because of a little available evidence and limitations from this study.

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
