The Effect of Eight Weeks of Resistance Training on the Plasma Levels of Preptin and Endothelin 1 in Men with Type 2 Diabetes

During recent decades, physical activity has become a key auxiliary tool in controlling many diseases, including diabetes. The aim of this study was to investigate the effect of 8 weeks of resistance training on the plasma levels of preptin and endothelin 1 in men with type 2 diabetes.

The current research is semi-experimental. The statistical sample of this study consisted of 38 men with type 2 diabetes, who were randomly divided into two groups of 19 experimental and control. Subjects in the experimental group performed 8 weeks of resistance training three sessions a week with moderate intensity. 24 hours before and after 8 weeks of training, plasma levels of preptin, endothelin 1, and indicators related to type 2 diabetes were measured by the ELISA method. Correlated t-tests and independent t-tests were used to examine intra-group changes. SPSS software was used to analyze the data (P≥ 0.05).

Correlated t results showed that plasma levels of preptin and insulin resistance index (P= 0.001) as well as plasma endothelin 1 (P= 0.001) decreased significantly in the post-test compared to the pre-test of the experimental group. has been found Also, the independent t-test results showed that the plasma levels of preptin, insulin resistance index (P= 0.001) and endothelin 1 (P= 0.002) were significantly lower in the post-test of the experimental group compared to the control.

According to the obtained results, it seems that doing resistance exercises improves glucose sensitivity by reducing preptin and reducing the possibility of blood pressure by reducing endothelin 1 in preople with type 2 diabetes.
