Background: the adipose tissue produces and releases peptides that contribute to various processes in body, including insulin resistance. The aim of this study was to investigate the effect of eight weeks of continuous aerobic training and high intensity interval training on Resistin and insulin levels and insulin resistance in type 2 diabetic male wistar rats. Methods: Twenty-four Wistar rats became diabetic in seven months. In next phase, after introducing with training environment, Wistar rats were randomly assigned into three equal groups of six each: control, continuous (20 minutes, 60% maximum speed) and intense interval (2 minutes of activity with 80% maximum speed, 2 minutes recovery with 30% maximum speed). The rats trained five time a week for eight weeks. Resistin gene expression and plasma insulin and glucose levels were measured before and after eight weeks. One-way ANOVA was used at P<0.05 for statistical analysis of data. Results: regardless the type of training, differences between pre and post training results was statistically significant for insulin, glucose, insulin resistance and Resistin (P<0.05). Interval training lead to significant changes in all factors except the Resistin gene expression (P<0.05). There was a significant relationship between changes in insulin resistance and Resistin gene expression (r=0.63). Conclusion: The results of this study showed that training is an effective factor in insulin resistance process and related factors in diabetes, and Resistin also play a role in this process, but it seems that regular training is more important factor than its type to change the Expression of Resistin.
