负载条件下D-核糖对大鼠游泳后血糖和血乳酸含量的影响

Effect of D-ribose on the Concentration of Rat Blood Sugar and Plasma Serum Lactic Acid after Loading Swimming

灌服不同剂量的D-核糖,测定大鼠在负重游泳后血糖和血乳酸的变化,旨在研究不同剂量D-核糖对因运动导致的大鼠心肌及骨骼肌功能降低的恢复作用。结果表明,运动后各剂量核糖实验组血糖浓度低于游泳对照组,且低于相对应剂量的核糖对照组;核糖实验组在恢复72h后,中、高剂量实验组血糖浓度均比运动后增高。运动后各剂量核糖实验组血乳酸浓度低于与其相对应剂量核糖对照组;恢复72h后,各剂量核糖实验组血乳酸浓度低于运动后及各相对应剂量核糖对照组。核糖可增强工作肌对血糖的摄取,为工作肌较好的供能,增强运动能力及糖贮备;促进乳酸循环,增强糖异生作用,防止乳酸堆积,有利于运动后机体的恢复。

In order to investigate the recovery of rat function of cardiac muscle and skeletal muscle after loading swimming, the rat blood sugar and plasma svrum lactic acid concentration were determined after loading swimming by filling rats with D-ribose of different doses. The results indicated that after swimming the concentration of blood sugar of the different dose Ribose Test Groups were lower than Swimming Control Group, and the same dose Ribose Control Group. After recovery 72h, the concentration of blood sugar of the Middle Ribose Test Group and the Low Ribose Test Group were higher than the concentration after swimming. After swimming the concentration of plasma serum lactic acid of the different dose Ribose Test Groups were lower than the same dose Ribose Control Croup. After recovery 72h, the concentration of plasma serum lactic acid of the different dose Ribose Test Groups were lower than the concentration after swimming, and the same dose Ribose Control Group. Ribose can improve the capability of the blood sugar absorption into muscles, provide the energy to muscles more effectively, and enhance the capability of exercise and the storage of sugar. Ribose can promote Cod circulation, enhance the formation of sugar from serum lactic acid, and prevent the accumulation of serum lactic acid. Ribose can enhance the recovery of body after exercise.
