Introduction: Myonectin is a key player in mediating lipid and glucose metabolism, and exercise training positively influences it by upregulating this myokine. However, the impact of different exercise regimens on myonectin levels is not well understood. This study aims to investigate the effects of three weeks of circuit resistance training on serum myonectin levels and lipid profiles in young men.
Material & Methods: Twenty sedentary young males (average age: 23.6 ± 3.2 years) participated, randomly assigned to circuit resistance training (n=10) and control (n=10) groups. Circuit resistance training, comprising nine sessions over three weeks with nine exercises per session at 60% of one-repetition maximum (1RM), was conducted. The control group maintained their daily routine. Blood samples, collected 48 hours post-training, underwent serum myonectin and lipid profile analysis using specialized kits. SPSS software version 24, ANCOVA tests (p < 0.05), were used for data analysis.
Results: The study revealed a significant increase in serum myonectin levels in the trained group compared to controls (p = 0.027). Additionally, the trained group exhibited a significant reduction in cholesterol and an increase in high-density lipoprotein (HDL) levels compared to controls (p < 0.05). Triglyceride and low-density lipoprotein (LDL) levels did not significantly change in the trained group compared to controls (p > 0.05).
Conclusion: This study demonstrates that short-term circuit resistance training (three weeks) significantly improves the lipid profile in sedentary subjects. The positive effect is partially attributed to the upregulation of myonectin levels induced by the training regimen.
