摘要：The present study was designed to determine the effects of Anoectochilus formosanus extract (AFE) on endurance capacity in mice. Four wk-old male mice were given either a vehicle (distilled water) or AFE (500, 1, 000mg/kg) through stomach intubations for 4wk. Mice were made to perform swimming exercises with weights attached to their tails corresponding to 10% of their body weight. Endurance capacity was evaluated by swim-ming time to exhaustion. The group treated with 1, 000mg/kg AFE showed a significant improvement ( p <0.05) in endurance performance time. The mice were made to swim for 15min with loads corresponding to 5% of their body weight. In the 1, 000mg/kg body weight of AFE administration group, blood lactate concentration was significantly lower than in the control group. In the AFE administration group, the plasma non-esterfied fatty acid (NEFA) was significantly increased by swimming exercise. AFE treatment also signifi-cantly decreased fat accumulation. Liver and gastrocnemius muscle glycogen after 15min of swimming remained at significantly higher levels in the mice fed 1, 000mg/kg of AFE as compared to the control group. These results suggest that AFE activated utilization of lipid more than glucose as the energy source for performance.
