Aim: The effect of concurrent training on the levels of hormone factors related to appetite and glucose metabolism are unclear. The aim of this study was to evaluate the effect of three months of concurrent training on Nesfatin, Resistin, Visfatin and peptide YY levels in obese women. Method: Twenty-six healthy obese women (age: 24.74 ± 4.38 years, body mass index: 31.50 ± 3.64 kg/m2) were randomly selected to participate in this study; then randomly assigned in two experimental (n=11) and control (n=10) groups. The training program was performed for three months, three sessions (15 to 30 minutes per session) at 60% of maximum heart rate and intensity endurance exercise on a cycle ergometer at 60% of one repetition maximum endurance exercise in resistance exercise at the same time. Plasma nesfatin, resistin, visfatin and PYY levels were assessed before and 48 hours after the training period. Data were analyzed using depended and independent t test at P≤0.05. Results: Nesfatin and PYY levels in the experimental group significantly were higher in post- test compared to control group (P<0.05). Resistin and visfatin levels in the experimental group in post-test significantly lower than control group (P<0.05). Conclusion: Based on the findings, concurrent training increases the levels of resistin and PYY, but decreases the visfatin and nesfatin levels. These training effects may have positive on appetite depressing and insulin resistance; also have prevent the incidence of obesity and diabetes problems.

Abstract
Aim: Nesfatin-1 is a novel adipokine secreted by adipose tissue and interfere in regulation of blood Glucose, improvement of insulin sensitivity, appetite regulation, energy homeostasis and metabolic function. Given the importance of resistance exercise in prevention and treatment of overweight and obesity, the purpose of this study was to determine the effect of eight weeks resistance training on plasma levels of nesfatin-1 in overweight women.
Method: Thirty-eight overweight women (age 34.84±5.70 y, BMI 28.82±3.65 kg/ m2, body fat percent 36.34±3.39 % and WHR 0.85±0.04 (means ± SD)) were randomly divided into 2 groups. Resistance exercise training (50 min/day, 60-70% 1-RM, 4 days/week). Fasting blood samples were collected to assess changes in plasma Nesfatin, insulin and glucose levels in before and after 2 months of the training program. Independent t-test and Pearson correlation coefficient were used for further analysis (P
