Moyenctin, is a new identified myokine and belongs to the CTRPs family which plays role in lipid and glucose metabolism. There is limited information available regarding the effects of exercise on Myonectin serum levels. The aim of this study was to investigate the effects of sucrose solution intake and resistance training (RT) with two different volumes on serum Myonectin levels and HOMA-IR in rats. 48 male Wistar rats (157.3 ± 1/38) were randomly divided into six groups; Control (C), Low volume RT (L), High Volume RT (H), Sucrose Control (SC), Sucrose Low volume RT (SL) and Sucrose High volume RT (SH). The RT groups were subjected to a resistance training program with the use of a ladder (3 days/week, for 8 week). Body weight and serum levels of Myonectin, Insulin, Glucose, and HOMA-IR were measured. Two way Anova Analysis shows that interaction (P< 0.05) between RT and Sucrose solution significantly increased Serum levels of Insulin (p=0.007) and HOMAL-IR (p=0.002). Consumption of Sucrose solution, significantly reduced Serum Myonectin (p=0.0001) and increased serum Glucose, Insulin and HOMA-IR (p=0.0001). Also RT significantly reduced Serum Myonectin, Insulin and HOMA-IR (p=0.0001). No correlation was found between serum Myonectin and Insulin Resistance in groups given normal foods (p=0.456) but in the groups given sucrose solution there was positive and significant correlation (p=0.0001). This investigation yields that RT can reduce Myonectin serum levels as well as Insulin Resistance. Thus it seems we can reach same improvement in insulin resistance and myonectin changes with low volume RT. However more study is needed to prove this.
