目的：探讨在低氧运动训练应激作用下，进行吸高浓度氧恢复对大鼠肝糖原和肌糖原含量的影响．方法：本研究以雄性 SD 大鼠53只，随机分为6组，分别进行低氧暴露、运动干预和吸高浓度氧恢复．在实验第4周末采样，测试大鼠肝糖原和肌糖原的含量．结果：经过4周的实验，低氧运动组肝糖原显著低于其他各组（P ＜0．05）．而其肌糖原显著低于常氧运动组（P ＜0．05），高于常氧安静组和低氧安静组，但没有显著性差异（P ＞0．05）；低氧运动高氧恢复组肝糖原含量低于常氧运动高氧恢复组，没有显著性差异（P ＞0．05），而显著高于其它各组（P ＜0．05）．对于肌糖原，低氧运动高氧恢复组显著高于常氧安静组、低氧安静组、低氧运动组（P ＜0．05）．结论：低氧环境不利于大鼠糖储备的恢复，如果低氧训练后进行吸高浓度氧恢复，则有利于大鼠糖储备的恢复．

Objective:to investigate the change of activity of SDH and MDH in skeletal muscle of rats af-ter training of hypoxia,exercise and hyperxia convalescence.Methods:53 male adult Sprague- Drawly (SD)rats were randomly divided into 6 groups,Were exposed to hypoxia,exercise intervention and recov-ery of high concentration oxygen absorption.After 4 weeks,to sample and to test liver glycogen and mus-cle glycogen of rats.Results:After 4 weeks,hypoxia exercise group was significantly lower than hepatic glycogen in the other groups (P <0.05).While the muscle glycogen was significantly lower than normox-ia exercise group (P < 0.05),higher than normoxia non- exercise group and hypoxia non - exercise group,but no significant difference (P < 0.05);Hepatic glycogen of hypoxia exercise and hyperxia con-valescence group was lower than normoxia exercise and hyperxia convalescence group,but no significant difference (P >0.05),and significantly higher than other groups (P <0.05).For muscle glycogen,hy-poxia exercise and hyperxia convalescence group was significantly higher than normoxia non - exercise group,hypoxia non- exercise group,hypoxia exercise group (P < 0.05).Conclusion:Hypoxia is not conducive to the recovery of rats with gln stockpile,if to absorb high concentration of oxygen after hypoxic training,it will help the recovery of rats with gln stockpile.
