The purpose of this study is to examine the effects of capsaicin and hydroxycitrate (HCA) ingestion on lipid metabolism during exercise in rats. Twenty-eight male Sprague-Dawley rats were randomly assigned 4 groups (CON: control, HCA: HCA supplementation, CAP: capsaicin supplementation, MIX: HCA plus capsaicin supplementation). All rats that have exercise trained and the diet supplemented in each group for 4 weeks. Blood glucose, lactate, FFA were analyzed as the blood energy substrates and liver and muscle glycogen were analyzed. Blood glucose concentration were significantly increased in the HCA and CAP (p＜.05). FFA concentration were significantly decreased in the CAP and MIX (p＜.05). Glycogen contents were significantly increased MIX (p＜.05). These results suggested that 4 weeks ingestion of capsaicin and HCA promotes lipid oxidation and spares carbohydrate utilization in rat during exercise. |
