The effects of phellinus linteus (PL) extract drink supplementation on metabolic parameters of skeletal muscle and blood in rats were studied. Thirty-three male rats at the age of 6 weeks were randomly divided into 4 groups: TS (tapwater drink sedentary group n = 8), TE (tapwater drink exercise group n = 8), PS (phellinus linteus drink sedentary group n = 8) and PE (phellinus linteus drink exercise group n = 9). PS and PE groups were given PL extract drink instead of water for 4 weeks. The rats of exercise groups were involved in swimming for 60 min · day?1, 5 days · week-1 for 4 weeks. Serum glucose level was significantly higher in the PS and PE groups than that of TS group (p < 0.01), and serum insulin level was not different among all groups. Serum leptin level was significantly lower in the TE group than that of TS group (p < 0.05). However, there was not significantly different between the PS and PE groups. In addition, serum ammonia and triglyceride level was significantly lower in the PS than that of TS group (p < 0.05), and muscle mitochondrial citrate synthase activities was not significantly different but was higher in both exercise groups compared to its sedentary groups, respectively. From these results, PL extract drink for 4 weeks have a crucial role in anti-fatigue effect in rats.
