Abstract: (504 Views)
Background: The effects of regular exercise on miRNA profile and oxidative stress indices are less known. The aim of this study was to investigate the changes in expression of miR-17 and oxidative stress indices in overweight and obese women following high-intensity functional training.
Methods: In this semi-experimental study, 22 overweight and obese women were randomly divided into two groups of high-intensity functional training (n= 10) and control (n= 12). The subjects of the training group performed high-intensity functional exercises 3 times a week for 8 weeks and intensity of rating of perceived exertion≥7. Before and after 8 weeks, blood samples were taken to measure expression of miR-17 gene, malondialdehyde (MDA), superoxide dismutase, glutathione peroxidase (GPx) and total antioxidant capacity (TAC). Analysis of covariance test was used to analyze the data.
Results: After eight weeks of high-intensity functional training, expression of miR-17 in the experimental group significantly decreased compared to the control group (P= 0.001). After eight weeks of high-intensity functional training, TAC (P= 0.0001), GPX (P= 0.007) and SOD (P= 0.001) increased significantly in the experimental group compared to the control group. No significant change was observed in MDA (P= 0.778).
Conclusion: The results of the present study showed that eight weeks of high-intensity functional training may lead to the reduction of miR-17 expression and the improvement of oxidative stress indices and antioxidant enzymes, which may be effective in improving metabolic indices and obesity complications.
