Abstract
Background: The use of complementary medicine in healthcare is increasing rapidly. Therefore, the aim of the current study was to investigate the effect of eight weeks of high-intensity interval training and moderate-intensity continuous training with quercetin supplementation on the gene expression of FOXO1 and ATG5 in the liver of diabetic obese rats.
Methods: In this experimental study, 42 male Wistar rats were considered research samples at eight weeks. Rats were induced with diabetes after eight weeks of a high-fat diet and familiarization with a laboratory environment and treadmill. Rats were divided into seven groups, and six rats were placed in each group (n=6): healthy control group, diabetes control group, diabetic quercetin group, high-intensity interval training with diabetes group, moderate-intensity continuous training with diabetes group, diabetic high-intensity interval training with quercetin group, and diabetic moderate-intensity continuous training with quercetin group. For one training group, eight weeks of high-intensity interval training, and for the other group, eight weeks of moderate-intensity continuous training on the treadmill were performed. Seventy-two hours after the last training session, liver tissues were isolated to check the gene expression of FOXO1 and ATG5. One-way analysis of variance test was used to check the difference between groups by SPSS version 26 software.
Results: Findings showed that by inducing type 2 diabetes, gene expression of FOXO1 increased (3.14 unit) (P<0.001) and ATG5 gene expression decreased (0.71 unit) (P<0.001). After eight weeks of training investigation, gene expression of FOXO1 and ATG5 decreased (P<0.001) and increased (P<0.001), respectively, in all training groups compared to the diabetic control group. There was no significant difference between the four training groups (P>0/05).
Conclusion: Both exercises with and without quercetin had a modulating effect on the gene expression of indicators related to the process of autophagy and blood glucose levels in the liver of diabetic obese rats.

Abstract
Background: Insufficiency of omentin-1 and 25-hydroxyvitamin D serum levels is associated with obesity, which is known as a threat to health. Therefore, the aim of the present study was to examine the effect of eight weeks of Pilates exercise on the serum levels of 25-hydroxyvitamin D, omentin-1, and lipid profile in overweight women.
Methods: In the present clinical study, 26 young overweight women were divided (block randomization method) into the Pilates exercise (PT, n= 13) and control group (CG, n= 13). The PT group performed Pilates exercises for eight weeks (three 60-min sessions per week). The movements started from simple and then increased in intensity and complexity based on the Borg index. The CG group had no training session for eight weeks. Blood samples were taken before the first training session and 48 hours after the last training session. Analysis of covariance was used for between-group comparisons.
Results: Findings showed a significant increase in the serum levels of 25-hydroxyvitamin D (p=0.008, SD= 4.78±0.12 ng/ml, effect size= 0.243) and HDL-C (p=0.04, SD= 6.44±1.05 mg/dl, effect size= 0.168), but a significant decrease in HOMA-IR (p=0.001, SD= 1.54±0.09, effect size=0.199), cholesterol (p=0.001, SD= 16.72±3.24 mg/dl, effect size= 0.326), and triglyceride (p=0.001, SD= 2.46±0.07 mg/dl, effect size= 0.209), and no significant change in omentin-1 (p=0.65, SD= 3.01±0.08 ng/ml) and LDL-C (p=0.58, SD= 2.46±0.07 mg/dl) serum levels in the PT group compared to the CG group.
Conclusion: It seems that this type of exercise training may play a critical role in controlling the health parameters and physiological status of the overweight women by having positive effects on serum levels of 25-hydroxyvitamin D and lipid profile, which are affected by body composition, weight, and fat.
