Induction of diabetes was done by a single intraperitoneal injection of streptozotocin (STZ) at a dose of 50 mg/kg dissolved in phosphate buffer (pH, 4.5). The training protocol consisted of 1 set of 10 climbing with the weight attached to the base of the tail, three times per week and for 8 weeks.
