本实验观察了大负荷运动训练和益气活血中药对血清磷酸葡萄糖异构酶（ＰＧＩ）活性的影响，结果表明：一堂大负荷专项技术课后即刻测定值较训练前安静值血清ＰＧＩ活性明显增高，差异非常显著（Ｐ＜００１），次晨安静值仍未恢复；服药１０天后，一堂大负荷训练课后与训练前自身对比：血清ＰＧＩ活性服药组增高不明显（Ｐ＞００５），对照组仍有明显增高（Ｐ＜００５）；服药组与对照组之间相比较，训练后服药组血清ＰＧＩ活性明显低于对照组（Ｐ＜００５）。提示大负荷运动训练可引起血清ＰＧＩ酶活性增高，益气活血中药有阻抑运动所致血清ＰＧＩ酶活性升高的作用 The experiment observed the effect of heavy load exercise training and Yiqi Huoxue Chinese medicine on the activity of serum PGI. The results showed that the serum PGI activity of a large load special technique immediately after training was significantly higher than that before training , The difference was very significant (P <0  01), the morning quietness has not yet recovered; 10 days after taking a large load training after training compared with their own before: serum PGI activity was not significantly increased medication group (P> 0  05 ), And the control group was still significantly higher (P <005). Compared with the control group, the serum PGI level in the medication group after training was significantly lower than that in the control group (P <005). It is suggested that exercise training with heavy load can increase the activity of serum PGI enzyme and enhance the activity of serum PGI enzyme induced by inhibition of exercise by supplementing qi and activating blood circulation
