| 摘 要： | 将昆明种4~6周龄雄性小白鼠随机分为补糖和补水对照组。每组均设安静组、定量运动组和力竭运动组。补糖采用浓度为5%葡萄糖与7%低聚糖的混合溶液。定量运动组做一次性静水负重游泳运动,持续时间为1h。力竭组与定量组运动形式相同,运动时间至力竭。分别测定血液、肝脏、骨骼肌和脑中的酮体(Ketone Body,KB),肝、骨骼肌糖原以及血糖、脑糖、血清游离脂肪酸(FFA)等指标。结果显示:与补糖组相比,1h游泳运动后补水组血清FFA有升高趋势,但无显著性差异,补水组小鼠血酮体浓度显著升高(P<0.05);力竭运动后补水组骨骼肌、肝脏中酮体含量显著高于补糖组(P<0.05)。提示:小鼠机体糖状况直接影响运动中的酮体代谢,运动性酮体代谢与体内糖储备以及脂肪分解状况有关。

| Abstract: | Forty-eight male mice were randomly divided into two groups,glucose-polymer supplementation group(GP) and water supplementation group(W).Each group was divided into three sub-groups,the rest control group,swimming-ration group and swimming-to-exhausted group.The glucose-polymer group was fed with 5%glucose 7%glucose-polymer solution 30 minutes before swimming,while the water supplementation group fed with distilled water of isodose and lasting for one hour exercise.The concentrations of blood ketone body(KB),liver KB,skeletal muscle KB and brain KB were measured as well as the level of liver glycogen,skeletal muscle glycogen,blood glucose,brain glucose and serum FFA.The results showed that there was a increased trend of blood FFA concentration in water supplementation group after one hour exercise compared with GP(P<0.05),while the concentration of KB is significantly increased in water supplementation(P<0.05).The level of the liver and muscle KB was higher in water supplementation group than in GP after exhaustion exercise(P<0.05).It suggests that the metabolism of ketone body is correlative with the status of glycogen stores and the fatty acid metabolism. |
