Effect of 8 weeks aerobic training with cinnamon extract supplementation on Lipocalin-2 and IL-1ß in insulin-resistant rats

Lipocalin-2 and interleukin-1 beta (IL-1ß) are two inflammatory markers affecting on insulin resistance. The aim of this study was to investigate the effect of aerobic training with cinnamon extract on blood levels of Lipocalin-2 and IL-1ß in insulin-resistant rats. : In this experimental study thirty-six Wistar male rats were randomly divided into four groups: control (n=9), aerobic training (n=9), cinnamon (n=9), and aerobic training+cinnamon (n=9). Insulin-resistance status induced by %10 fructose solutions during 5 weeks. Training groups subjected to a 5-day per week aerobic training program (with 75-80% VO2max) for 8 weeks. Supplementayion groups subjected to injected 200 ml/kg/day cinnamon extract. Exercise training significantly reduced Lipocalin-2 compared to the control group, and compared to extract group (P<0.05). Also, in all three experimental groups, IL-1 beta decreased significantly compared to control (P<0.05), and significant decrease was observed in the extract group compared to the training group and extract (P Results of this study indicated that aerobic training with cinnamon extract more than any of them alone effects on reduction IL-1ß. But the effect of the combination of aerobic training and cinnamon extract on lipocalin-2 requires further investigation.
