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: The purpose of this study was to examine the response of the visfatin to acute endurance exercise pre and post 8-weeks trainingin untrained obese healthy men. Method: Twenty two subjects (age 29.06±3.83 years, weight 90.96±4.68 kg, height 171.3±4.88 cm, and BMI 30.76±1.8 ...

Aim: The purpose of this study was to examine the response of the visfatin to acute endurance exercise pre and post 8-weeks trainingin untrained obese healthy men. Method: Twenty two subjects (age 29.06±3.83 years, weight 90.96±4.68 kg, height 171.3±4.88 cm, and BMI 30.76±1.8 kg/m2) were volunteered to participate in the current study. The subjects were divided randomly into two experimental (n=11) and control (n=11) groups. Experimental group participated in 8-week endurance training program three times per week. Exercise intensity increased from 60 percent of maximum heart rate to 65 to 70 percent after 4thweeks until the end of training program. Acute exercise test (cycle ergometer exercise, 30 min at 60 percent of maximum heart rate) were employed before and after training period. Blood samples were collected before, immediately, and 30 min after acute exercise at before and after endurance training period to measure plasma visfatin variations. Results: The results by two-way Anova with analysis showed before training period, visfation levels changes were not sigificant after acute exercise , immediately and 30 min aftery in both groups. Conclusion: These data indicate that endurance training is associated with decrease in resting plasma visfatin and body fat in obese men. Moreover, one bout of endurance training can decrease the plasma visfatin in response to acute exercise.
