Introduction: Diabetes is a disease caused by a lack of insulin secretion or a decrease in tissue sensitivity to insulin. The aim of this study was to investigate the lipid-lowering effects of endurance training (ET) with cinnamon (C) extract in streptozotocin (STZ)-induced diabetic rats.Methods: Thirty-two diabetic rats were divided into four groups of 8 rats, including 1) cinnamon, 2) training, 3) training+cinnamon and 4) sham groups. During four weeks, groups 1 and 3 received daily 100 mg/kg C perennially, and groups 2 and 3 ran on treadmill five times per week for 60 minutes each session at a speed of 8 to 16 m/min. Data were analyzed using paired sample t test and one way ANOVA and Tukey’s post-hoc tests (p≤0.05).Results: cinnamon, training and training+cinnamon significantly reduced TG, LDL and VLDL levels as well increased HDL (P=0.001) in compare with sham group, training+cinnamon significantly reduced Cho and VLDL (P=0.001) in compare with sham group; training+cinnamon had more effect on decrease of Cho (p=0.02) and LDL (p=0.002) as well as increase of HDL (P=0.004) rather than training. Also cinnamon (P=0.03) and training (P=0.04) significantly reduced VLDL in compare with sham group.Conclusions: Although training and cinnamon have lipid-lowering effect in diabetic rats, nevertheless it seems training simultaneously with cinnamon administration has better effect on improving lipid profile compare to training alone.
