有氧运动锻炼对LD含量和LDH、ALP、ACP、CK活性影响的研究

Influence of Aerobic Exercise on LD Content and Activity of LDH,ALP,ACP,CK in Blood Plasma

为了探讨有氧运动锻炼对人体在不同功能状态下血 L D(乳酸 )代谢和 L DH(乳酸脱氢酶 )、AL P(碱性磷酸酶 )、ACP(酸性磷酸酶 )、CK(肌酸激酶 )活性的影响 ,将 4 2名中学生随机分为一般锻炼组、强化锻炼组和对照组。对两运动组分别实施不同的有氧运动处方后 ,与对照组相比 ,结果发现 :安静状态时 ,血清中 L D含量明显降低 (P<0 .0 5 ) ,L DH活性极显著升高 (P<0 .0 0 1) ,ACP、CK活性呈升高趋势 ,AL P活性呈下降趋势 ,但均无显著性差异 (P>0 .0 5 ) ;定量负荷和极量负荷运动后 ,L D含量无变化、L DH活性仍显著升高 ,ACP、AL P、CK活性的变化趋势基本与安静状态时相同 ,只是强化锻炼组 AL P活性在极量负荷时显著低于对照组水平。这说明 ,短期有氧运动锻炼能够有效地降低人体在安静状态时血乳酸的生成和促进在不同功能状态下 L DH活性的提高 ,但对 ACP、AL P。

In order to investigate the influence of aerobic exercise on LD,LDH,ALP,ACP and CK,42 students are divided into three groups.Group one takes ordinary exercise,group two takes maximal exercise,group three with control group.After exercise,comparing group one and two with control group.The result shows that LD content of two exercise groups in blood plasma is much higher,LDH activity is much higher (P<0.05),ALP,CK activity tend to increase,ACP activity tend to decrease (P>0.05) at rest.LD content does not change,LDH activity is still much higher,ALP,ACP,CK activity change is above same in the end of fixed load and maximal load,ACP activity of group two is much lower in maximal load comparing with control group.It indicates that aerobic exercise can reduce production of LD at rest and increase activity of LDH.There has no effect on ALP,ACP,CK.
