Abstract The aim of this study was to investigate the influence of high intensity interval training on adipose tissue PAI-2 and MMP-2 mRNAs expression in rat with high-fat diet-induced metabolic syndrome. In this experimental study, 32 male Wistar rats (120 to 130 g) were selected and after 12 weeks of high-fat diet and modeling of metabolic syndrome were randomly divided into 4 groups: control, metabolic syndrome (Mets), high intensity interval training (HIIT) and Mets + HIIT. The HIIT program included 5 to 10 intense running on the treadmill with an intensity of 80 to 95% of the maximum speed and in slow running with a speed of 55% of the maximum speed with a zero slope of the treadmill for 8 weeks. Data were analyzed using one-way analysis of variance (ANOVA). The results of one-way analysis of variance showed that there was a difference between the mean expression of MMP-2 and PAI-2 mRNA in adipose tissue of male rats with metabolic syndrome in different groups (P = 0.001). However, HIIT improve this gene after Mets in adipose tissue (p<0.05). It seems that HIIT program improve metabolic syndrome with controlling PAI-2 mRNA and have an anti-inflammatory effect in adipose tissue. However, it need to more studies especially on human sample.
