Background and Objective: There are controversial reports about the effect of training on serum level of visfatin and TNF-α Cytokine .This study was done to evaluate the effect of 8 weeks of aerobic training on serum level of visfatin and TNF-α in non-athletic young women. Methods: In this quasi-experimental study, thirty non-athletic healthy women were non-randomly based on the weight, height, BMI index and body fat percentage divided into two control and training groups. In the training group 8 weeks of aerobic exercise on a stationary bicycle 3 times a week was performed. Serum level of visfatin and TNF-α was measured using ELISA method, prior and at the end of 8th week of training while the subjects were fasted for 12-14 hours. Results: At the end of 8 weeks of aerobic exercise, serum level of visfatin and TNF-α significantly reduced in the training group in comparison with controls (P<0.05). Conclusion: Eight weeks of aerobic training reduces visfatin and TNF-α serum level in non-athletic healthy women.
