Abstract
Aim: Cytokines preptin and adropin have a regulatory role in energy metabolism, but their mechanism in response to exercise in obese prediabetic subjects is not well understood. The aim of this study was to investigate the effect of 8 weeks of intense circuit resistance training on serum levels of preptin and adropin in obese men with prediabetes. Method: In this semi-experimental study, 30 obese prediabetic men were randomly divided into two experimental and control groups (15 people in each group). The experimental group participated in the HIRT program with an intensity of 80-85% of one maximum repetition for 8 weeks and three sessions for 60 minutes each week. Serum levels of adropin, preptin, and insulin were measured on two occasions before and after the test. Data analysis was done using independent t test and paired t test at a significance level of P<0.05. Results: The levels of preptin (P=0.002), insulin (P=0.007), glucose (P=0.001), insulin resistance (P=0.001) decreased significantly in the experimental group compared to the control group. While the level of adropin showed a significant increase (P=0.003). Paired t results showed a significant decrease in preptin (P=0.001, -0.20 percent), an increase in adropin (P=0.001, 21.5 percent), and a decrease in indicators related to diabetes insulin (P = 0.001) P, -17.5 percent), glucose (P=0.001, -19.1 percent) and insulin resistance (P=0.001, -17.5 percent) in response to the exercise protocol (P<0.05). Conclusion: Probably, HIRT exercises can have a beneficial effect on adropin, preptin and some diabetes indicators and body composition in pre-diabetic obese men.
