Background: Visfatin and resistin are adipokines involved in metabolic regulation and physiological processes. Objectives: This study aimed to investigate the effects of eight weeks of aerobic training with different intensities on serum levels of resistin and visfatin in obese male rats. Methods: 24 adult obese rats (weight: 250 to 300 gr, BMI > 30 g/cm2) divided into three groups: aerobic training with 28 m/min (moderate intensity), aerobic training with 34 m/min (high intensity) and, control group. All training groups did exercise training for 8 weeks (5 sessions/per-week for 60 minutes per session). 48 hours after the training period, the level of serum visfatin and resistin levels was measured. Results: Unlike the levels of resistin concentration (P = 0.001) in different groups, there was no significant difference between visfatin levels in all three groups. Resistin concentration was not significantly changed in the moderate-intensity group compared to the control group, (185.10 ± 12.85 vs. 202.76 ± 17.39) (P = 0.05). There was a significant difference between the high intensity and control groups (P = 0.001). There was no significant difference in visfatin concentration in MI and HI groups compared to the control group (P > 0.05). Conclusions: There is a significant difference in the levels of resistin concentration in different groups. There was no significant difference between visfatin levels in all three groups. Therefore, it seems that aerobic training with high intensity has a better effect on the prevention of obesity and cardiovascular disease.
