Abstract
This study aimed to investigate the effect of quercetin supplementation and training on myostatin and follistatin levels in the heart tissue of diabetic rats. Methods: For this purpose, 50 10-week-old male Wistar rats with an average weight of 237±33 grams were randomly divided into five groups of 10 including: healthy control, diabetes, diabetes+supplement, diabetes+exercise, and diabetes+supplement+exercise. . The training protocol includes five sessions per week for eight weeks on a treadmill without a special slope. The rodents ran for 60 minutes at a speed of 25 meters per minute in each session.and the supplement groups received 50 mg/kg quercetin daily by gavage. The results showed that the difference in myostatin levels among the groups is significant (P=0.001). There was a significant decrease in myostatin levels between exercise+supplement+diabetes group with diabetes (P=0.002). There was also a significant difference between the supplement+diabetes and exercise+diabetes groups (P=0.009). Also, the results showed that the difference in follistatin levels among the groups is significant (P=0.001). The results showed that follistatin levels in the heart tissue increased significantly between the groups of diabetes, exercise+diabetes, supplement+diabetes and exercise+supplements+diabetes with the control group (respectively: P=0.005; P=0.001; P=0.001; P = 0.001).
It seems that moderate intensity aerobic exercise and quercetin supplementation have a positive and beneficial effect on the levels of myostatin and folstatin.
