Changes of RBP-4 and insulin resistance after 8 weeks of aerobic training in type 2 diabetic rats
Author(s):
Abstract:
Aim: RBP4 is an adipokin that participates in insulin function and glucose metabolism. The purpose of this study was to examine the effects of aerobic training on serum RBP4 levels and insulin resistance index in type 2 diabetic male rats.
Method
Eighteen male 8-week-old wistar rats (233.6±13.1 g) were selected as sample research. Diabetes was induced by using nikotinamid and streptozotocin. Five days after inducing diabetes, fasting blood was measured using blood glucose strips and rats that the level of fasting blood glucose was between 400-126 mg was selected as diabetic. Rats were randomly and According to homogenization of body weight assigned into two groups including control (n=9) and trained (n=9).Rats in the training groups carried out an 8-week exercise program on a motorized treadmill with 1025 m/min for 15-40 min/day and a 5% slope for 5 days. Serum RBP4 levels was measured with Elisa method and insulin resistance was measured by HOMA-IR index.Results
Induction of diabetes caused a significant increase in body weight (p=0.001) and serum RBP4 (pConclusion
it seems that 8 weeks aerobic training with 60-80% vo2max can be effective to decrease the serum RBP4 levels and insulin resistance index in type 2 diabetic patients. Language:
