Introduction: Considering the synthesis and release of myokines from muscle tissue during exercise and the relationship of myokines with the development of strength and increase in muscle volume, the purpose of this study is to investigate 12 weeks of resistance training on the serum levels of myonectin and FGF- There were 21 middle-aged men.
Methods: In a semi-experimental study, 40 middle-aged men of Arak city (mean age 38.27 ± 6.02 years, weight 77.12 ± 11.23 kg, height 174.05 ± 7.22 cm) were selected and randomly placed in two resistance training groups (20 people) and control (20 people). The training group performed 12 weeks of resistance training 3 times a week with an intensity of 65-80% of maximum strength. Blood was taken from all the subjects 48 hours before and after the intervention, and serum levels of myonectin and FGF-21 were checked by the ELISA method. After checking the normality of the data, they were analyzed by the correlation t-test and independent t-test at a significance level of less than 0.05.
Results: Resistance training caused a significant increase in the serum level of myonectin (P = 0.001) and the serum level of FGF-21 (P = 0.001) and also decreased the percentage of fat (P = 0.417) in middle-aged men.
Conclusions: According to the results of this study, it seems that resistance training can have positive adaptation by increasing the serum levels of myonectin and FGF-21 in the regulation of muscle mass, hypertrophy process, angiogenesis process, and Improve the body's metabolism.
