Abstract
Background and Purpose: Adropin, a hepatic hepatokine, plays a role in regulating lipid and glucose metabolism. This study aimed to investigate the effect of progressive and constant resistance training on serum and hepatic adropin levels in sugar solution-fed rats .Methods: Thirty-two male Wistar rats (4-6 weeks old) were randomly divided into four groups: healthy control, sugar control, progressive training + sugar, and constant load training + sugar. After 8 weeks of consuming a 10% sugar solution, a training protocol (3 sessions per week for 8 weeks) involving ladder climbing with tail weights was implemented. The dietary intervention continued until the end of the study (approximately 16 weeks). Results: Sugar consumption significantly increased the body weight of the sugar control group compared to the normal control group (P=0.01). The progressive training group showed less weight gain compared to the sugar control group during the study period (P=0.01). Hepatic adropin concentration was significantly higher in the progressive training group compared to the constant load training group (P=0.03). However, no significant difference was observed in serum adropin levels (P=0.57). Furthermore, there were no significant differences in hepatic triglyceride and cholesterol levels among the different groups (P>0.05) .Conclusion: The findings suggest that the type of resistance training protocol can differentially impact hepatic adropin concentration and mitigate the negative effects of sugar consumption on weight gain. Conversely, the effects of these two types of training on serum adropin, hepatic triglyceride, and cholesterol levels appear to be similar.
