The Effect Of Eight Weeks Of Endurance Training On The Expression Of Glutathione Peroxidase 4 And Malondialdehyde In The Soleus Muscle Of Aged Aale Wistar Rats

The increase of iron due to aging affects the process of ferroptosis, and the final product of lipid peroxidation, MDA, is the central regulator of ferroptosis. Therefore, the aim of the research was to determine the effect of eight weeks of endurance training on the expression of GPX4 and MDA in the soleus muscle of aged male rats.

This study is of an experimental type. 20 healthy rats were divided into two groups of 10 each: training group and control group. The training was done incrementally for eight weeks. 48 hours after the last training session, the soleus muscle of mice was surgically removed and the amount of variables was measured by gene expression and ELISA methods.

There was no significant difference in the level of GPX4 gene expression in the soleus muscle of exercise group rats compared to control group rats (p=0.4079). But the amount of MDA in the training group was significantly reduced compared to the control group (p=0.0028).

According to the findings of the present research, it seems that the effect of endurance training in this research shows a decrease in ferroptosis. The absence of a significant difference in the level of GPX4 gene expression is a sign that endurance training with this intensity does not affect it.
