Background and Aim: Decreased levels of testosterone and dehydroepiandrosterone sulfate (DHEA-S) have been reported as anabolic risk factors for  health in young people. The aim of the present study was to investigate the effect of resistance training and resistance training with neurofeedback on serum levels of testosterone and DHEA-S in young males. 
Materials and Methods: A total of 30 young males were divided into resistance training (n=10), resistance training and neurofeedback (n=10), and control (n=10) groups. The training groups performed resistance training and neurofeedback training for eight weeks. In both pre- and posttests, the levels of testosterone and DHEA-S were measured. Combined analysis of variance was used to compare the means between groups and paired t-test was used to compare the means within the group.
Results: Compared to control group, serum testosterone levels increased significantly following resistance training and resistance training with neurofeedback in young males (p=0.01). Also, dehydroepiandrosterone sulfate levels, compared to resistance training group, had a significantly higher increase in the resistance training with neurofeedback group (p=0.01). Also, serum cortisol levels were significantly reduced (p = 0.001) in the resistance training with neurofeedback group, but its reduction in the resistance training group was not found to be significant (p = 0.31), as
compared with the control group. .
Conclusion: Anabolic and catabolic hormones appear to respond better to electrical stimulation of the brain with resistance training.
