Men of training groups performed circuit resistance training 4 times a week with given intensities for 6 weeks. The blood sampling was conducted to determine the levels of neuregulin-1, leptin, insulin, and glucose before, and after 6 weeks. Data were analyzed using the analysis of covariance and paired T-test.<br />Results: The plasma neuregulin-1 (P= 0.0001), leptin (P= 0.009), and insulin (P=0.013) levels were significantly increased in the training groups compared with the control group while there were no significant differences between the glucose (P=0.27) level of groups.<br />Conclusion: The results showed circular resistance training plays a significant role in promoting the performance of NRG-1 and leptin.
