The Effect of resistance exercise training on calcineurin signaling expression in skeletal muscle of diabetic rats was studied. Male Wistar rats were randomized to one of four groups: control (C), trained (T), STZ-induced diabetes (D), and (Streptozotocin ) STZ-induced diabetes plus training (DT). Diabetes was induced by the i.p. injection of STZ (Sigma), 55 mg/kg of body weight in a 0.1 M citrate buffer (pH 4.5). The results showed that, Typical Type 1(diabetes mellitus) DM hyperglycemia occurred in D and DT groups with increased fasting glucose (P<0.001). Moreover, diabetic and resistance training rats showed a significant decrease in total weight (P<0.001). Significant different observed among groups in expression of(Regulator of calcineurin1) RCAN-1 mRNA (P<0.05). As RCAN- 1(messenger ribonucleic acid) mRNA increased in T group compare to C group (P<0.05). There was a significant decrease of RCAN-1 mRNA in soleus muscle D group compared with C group (P<0.05). There was not difference in DT group compared with C and D groups (P>0.05).
