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.

Abstract
The aim of this study was the effect of a course of aerobic exercises on depression and oxidative stress factor changes in the hippocampus and prefrontal cortex of rats with Alzheimer's disease. For this purpose, 40 8-week-old male Wistar rats with an average weight of 237±33 grams were randomly divided into four groups of 10: control, exercise, Alzheimer's, and exercise+Alzheimer's. The training protocol consisted of 12 weeks of running on a treadmill at a speed of 12 meters per minute and for 30 minutes in each session. At the end of the training period, the tests of feeding sensation suppression and tail suspension were performed to estimate depression as well as hippocampal and prefrontal malondialdehyde levels using the Bradford method. Also, in order to induce Alzheimer's, an amount of three mg/kg of streptozocin in a volume of five microliters of sterile distilled water was injected into the ventricle of the brain. The results showed that exercise training caused a significant decrease in depression in eating delay tests and immobility duration in Alzheimer's rats. Also, exercise caused a significant decrease in malondialdehyde levels in the hippocampus of Alzheimer's rats, while a significant difference was observed in the prefrontal area. It didn't happen. It seems that sports activity creates immunity against Alzheimer's and is probably effective in preventing depression in Alzheimer's patients.
