The purpose of this study was to investigate the effects of endurance training on muscle NHE1 and NBC1 gene expressions in type 2 diabetic rats. Methods: Male wistar rats (n=40), 4weeks old and 93.7±9.8g, were randomly selected and divided into control, diabetic control and diabetic training groups. The Endurance training was performed for 7 weeks on diabetic training groups (running on treadmill forrodent). NHE1 and NBC1 gene expression were determined by Realtime-PCR technique. The

... between groups in variables were determined by an independent t-test using REST Software. Results: NHE1 mRNA expression reduced significantly in EDL and Soleus by 25% and 19% in the diabetic control group compared with the control group, respectively (P<0/05).NHE1 mRNA expression also reduced significantly in EDL and Soleus by 35% and 29% in the diabetic control group compared with the control group, respectively (P<0/05).Endurance training increased NHE1 and NBC1 geneexpressions in both EDL and Soleus in the diabetic training group. Conclusion: The present study showed that NHE1 and NBC1 mRNA expressions decreased significantly in the diabetic control group and endurance training increased NHE1 and NBC1 mRNA expressions in the diabetic trained group leading to normalizing the mRNAs in diabetic trained group.
