Abstract
Background: The effect of training on the gene expression of GLUT4 and insulin receptor (IR) has been investigated in some studies, but the simultaneous effect of swimming training along with cinnamon consumption is unknown. Objective: This study aimed to examine the effect of six weeks of swimming training with cinnamon consumption on the gene expression of GLUT4 and IR in the brown adipose tissue of diabetic rats. Methods: In this experimental study, 28 diabetic rats were randomly divided into four groups of seven animals, including 1- control (C), 2- cinnamon (Ci), 3- swimming (S), and 4- swimming plus cinnamon (S + Ci). Rats in groups 3 and 4 trained for six weeks and five sessions. Groups 2 and 4 received 200 mg/kg/day. Data were analyzed using one-way analysis of variance and Tukey’s post hoc test at the level of P ≤ 0.05. Results: The gene expression of GLUT4 and IR in the S, Ci, and S + Ci groups was significantly (P = 0.001) higher than the control group. Also, the gene expression of GLUT4 and IR in the S group was significantly (P = 0.001) higher than the Ci and S + Ci groups. Conclusion: Swimming training and cinnamon consumption and their simultaneous implementation had a significant effect on increasing the gene expression of GLUT4 and IR in the brown adipose tissue of diabetic rats. On the other hand, swimming training alone had a greater effect than cinnamon consumption and swimming plus cinnamon consumption.
