Comparison of the Effect of HIRT and TRT Exercises on Irisin and Insulin Resistance Index in Overweight Men in Hamadan

The aim of this study was to compare the effect of high-intensity resistance training (HIRT) and traditional resistance training (TRT) on serum irisin and insulin resistance index in overweight men in Hamadan. In this study, 36 overweight men with a body mass index above 24 were selected as a sample and randomly divided into three control groups: HIRT and TRT. Subjects in the TRT training group performed resistance training with an intensity of 70% of one maximal repetition and the HIRT training group performed an eight-week resistance training protocol with an intensity of 85% of a maximal repetition. Before and after exercise, irisin, insulin resistance index Waist period size, fasting glucose, fasting insulin and body mass index were measured, and the results were analyzed using one-way analysis of variance and significant using Tukey post hoc test.The results showed that high-intensity resistance training (HIRT) caused significant changes in irisin (P <0.05) and insulin resistance index (P <0.05), but these changes were not significant in the traditional training group (TRT) (P> 0.05). ).Both training methods caused changes in serum irisin levels and insulin resistance index in overweight men compared to the control group, but high-intensity resistance training had a greater effect on changing serum irisin levels and insulin resistance index in overweight men than traditional exercises.
