Title

The Effect of a Detraining After Resistance Training on the Histochemical Expression of Potassium Channels and Mitochondrial Biogenesis of Heart Tissue in Male Rats

Pages

  230-245

Abstract

 Aims: Detraining may affect cardiovascular adaptations. The present study aimed to investigate the effect of a Detraining period followed by Resistance training on immunohistochemical expression of ATP-sensitive Potassium channels and Mitochondrial biogenesis of heart tissue in male rats. Methods & Materials: The present study was experimental. Thirty male Wistar rats were randomly divided into four groups (control, control-Detraining, Resistance training, and resistance-Detraining training). The control group was sacrificed at the beginning of the study, and the control-Detraining group did not exercise for 11 weeks. The Resistance training group performed eight weeks of training. The resistance-Detraining group did not train for three weeks after training. One-way analysis of variance and Tukey’ s post hoc test were used for statistical analysis. Findings: The expression of KIR6. 2, SUR2a, PGC1α , and TFAM in the heart tissue of the control-Detraining group was significantly lower than those in the Resistance training group (P=0. 001). Also, they were significantly higher in the Resistance training group compared to those in the resistance-Detraining group (P=0. 001). PGC1α expression in the resistance-Detraining group was higher than in the control-Detraining group (P=0. 001). Conclusion: Resistance training increases PGC1α and TFAM in the heart tissue of rats by increasing the expression of KIR6. 2 and SUR2a. But lack of exercise reduces the expression of Potassium channels and factors that increase Mitochondrial biogenesis.
