The acute effects of high intensity interval training (HIIIT) on PGC-1α and FNDC5 genes expression in diabetic rats

Change in adipose tissue phenotype caused by exercise training is new theory that as result of muscle FNDC5 gene expression. The aim of the present study is to investigate the acute effects of high intensity interval training (HIIT( on PGC-1α and FNDC5 genes expression of diabetic rats. In this study, 18 diabetic wistar rats(12 week- age, 220-240 gr- weight) were assigned to three groups: high intensity interval training Immediately (HIIE0)(n=6), high intensity interval training 2hours later (HIIE2)(n=6) and control(C)(n=5). Both HIIT groups activated on the treadmill with 90-95% vo2max in the 12 interval-one minute period and 1 minute rest intervals. Real time PCR method was used for the relative expression of mRNA FNDC5 and PGC-1α. One-way ANOVA and Tukey Post hoc test has used to data analysis, the level of significance has been consider at 0/05. Data Analysis showed significant differences Research groups in expression of mRNA FNDC5 and PGC-1α (p≤0/01.) Tukey test showed, FNDC5 and PGC-1α gene expression In the 2 groups high intensity interval training(HIIT0-HIIT2) compared to the control group significantly increased (p≤0/01).
