探讨了普洱茶熟茶抗疲劳的作用。将昆明种小鼠随机分为4组（20只/组）,分别为空白对照组和普洱茶熟茶低、中、高剂量组,分别饲喂0.9%生理盐水和0.5、1.0、2.0 g/kg的普洱茶熟茶。按照小鼠体重给予不同体积的受试物,自由摄食与饮水。连续饲喂30 d后,每组选取10只小鼠进行负重游泳实验,记录小鼠力竭游泳时间;剩余小鼠检测血乳酸(BLA)、血尿素氮(BUN)、血乳酸脱氢酶(LDH)活力及肝糖元（LG）、肌糖元（MG）。结果表明,与空白对照组相比,普洱茶熟茶低、中、高剂量组小鼠负重游泳时间均有延长,BLA、BUN含量降低,LDH活力升高,MG、LG含量也有显著提高,且以高剂量的普洱茶熟茶抗疲劳作用最为明显。

The anti-fatigue effect of fermented pu-erh tea on mice was investigated. Kun-ming mice were selected and divided into 4 groups: blank control group was fed with 0.9% normal saline, low-dose group, middle-dose group and high-dose group were fed with 0.5 g/kg, 1.0 g/kg, and 2.0 g/kg of fermented Pu-erh tea respectively. In accordance with the body weight of the mice, different amounts of test sample were fed with. The mice were allowed to drink and eat freely. After 30 d, ten mice from each group were selected for the weight-loaded swimming test and recorded the exhaustive swimming time. For other mice, the blood lactic acid(BLA), blood urea nitrogen(BUN), the activity of lactate dehydrogenase(LDH), muscle glycogen(MG) and liver glycogen(LG) were determined. Results showed: Comparing with blank control group, three groups of fermented Pu-erh tea showed a prolonged weight-loaded swimming time. The contents of BLA and BUN were reduced while the activity of LDH was increased. The contents of MG and LG were increased significantly. Among the three fermented Pu-erh tea groups, the high-dose group showed the best effect.
