Introduction: Obesity and overweight are among the risk factors of some chronic diseases. The purpose is to investigate the effect of intermittent resistance training with different intensities on toll-like receptors 2 and 4 and dectin-1 levels in obese men. Methodology: 44 obese men aged 20-30 years old in Tabriz city were selected and divided into 4 control groups, intermittent resistance training with low, moderate and high intensity. The subjects did their exercises for 12 weeks, three sessions a week with 40%, 60% and 80% 1RM. 48 hours before the first session and 48 hours after the last training session, the subjects' personal characteristics and Dectin-1, TLR4 and TLR2 levels were measured. Results: The research findings showed that 12 weeks of intermittent resistance training with different intensities caused a significant difference in the levels of Dectin-1 (P=0.001), TLR4 (P=0.001) and TLR2 (P=0.001). P) in different groups. This difference is significant for the TLR4 in the moderate intensity (P=0.01) and high intensity (P=0.01) training group compared to the control. Also, a significant difference in the TLR2 were seen in the low (P=0.001), medium (P=0.01) and high (P=0.01) intensity training group compared to the control. Also, a significant difference was observed in the moderate (P=0.01) and high (P=0.01) exercise group compared to the control in dectin-1 level. Conclusion: It seems that intermittent resistance training with different intensities for 12 weeks can reduce Dectin-1, TLR4 and TLR2 levels in obese men, and this improvement is better in high and medium intensities.

Aims: The purpose of this study was to investigate the effect of Interval resistance training with different intensities on the levels of interleukin-6 (IL-6), tumor necrosis factor-alpha (TNF-α) and neuroglin-4 (NRG-4) in obese men.Methods: In this semi- experimental research, 44 obese men aged 20-30 years old in Tabriz city were selected and divided into 4 control groups, low intensity Interval resistance training with low intensity, medium intensity and high intensity. In the continuation, the subjects of the resistance training group performed their training program for 12 weeks, three sessions a week with 3 different intensities (40% 1RM with 20 repetitions, 60% 1RM with 12 repetitions and 80% 1RM with 20 repetitions) and 48 hours before the first training session and 48 hours after the last resistance training session, the subjects' personal characteristics and serum levels of IL-6, TNF-α and NRG-4 were measured by ELISA. Results: The research findings showed that 12 weeks Interval resistance training decreased serum levels of IL-6 in group with high intensity (P=0.01) and increased serum levels of NRG-4 in exercise groups with different intensities(P=0.001) in obese men, but it had no significant effect on TNF-α levels (P=0.05). The dcrease in IL-6 and increase in neuroglin-4 levels in the high intensity Interval resistance training group (P=0.02) was the most compared to other groups (P=0.02 and P=0.001; respectively). Conclusion: It seems that Interval resistance training with different intensities can improve inflammatory indices and neuroglin-4 in obese people, and this improvement was more prominent in high-intensity resistance training.
