Considering the synthesis and release of myokines from muscle tissue during exercise and the relationship of myokines with strength development and muscle mass increase, the aim of the present study was to investigate the effects of a period of resistance training, detraining, and retraining on serum levels of myonectin and FGF-21 in middle-aged men. Methods: 20 middle-aged men with an age range of 35-50 years were selected and randomly divided into 2 groups. Subjects in the training group experienced 3 months of resistance training, 6 months of detraining, and 3 months of retraining. Also, the retraining program was followed using the same resistance training program. Blood samples were taken in the two training and control groups in 4 stages. Also, serum levels of myonectin and FGF21 were measured using the ELISA method. Results: The results showed that serum levels of myonectin and FGF-21 increased significantly in the post-training and retraining stages compared to before training and the end of non-training. In addition, serum levels of myonectin and FGF21 increased after retraining compared to after training, but this was not significant. In addition, in the control group, no significant changes were observed in serum levels of myonectin and FGF-21 in any of the phases. Conclusion: It seems that performing a course of resistance training and retraining may lead to an upregulation of cytokines, which can be a suitable tool for accelerating the hypertrophy process and inhibiting atrophy during injury or aging.
