抗阻训练引起血清肌酸激酶变化的分析

为探讨抗阻训练后血清肌酸激酶的变化情况，以安徽省优秀男子皮艇运动员为研究对象，进行为期8周的抗阻训练。结果表明，在通过8周抗阻训练后，开始准备阶段，运动员血清CK的活性与正常人无差异；在肌肉肥大训练阶段和肌力训练，血清CK活肚在第1周、第4周都大幅度上升，与准备阶段相比，均有显著性差异（P〈0．01），说明强度为大强度，符合训练目的。随着机体对训练强度的适应，第2、3周和第1周（P〈0．05）、第5周、第6周和第4周（P〈0．05）相比CK活性逐渐降低，说明机体对训练强度产生一定的适应。力量耐力训练阶段，第7、第8周CK酶活性和准备阶段相比，无显著差异（P〉0．05），说明为一般强度，机体适应该强度。

The Analysis Of The Change Of Serum Creatine Kinase After Resistance Training

To explore the change of serum creatine kinase after resistance training, elite male kayak athletes in Anhui province are conducted as the subjects, the study is arranged to continue a resistance training for eight weeks. The results showed that the resistance training, when it was started in preparatory stage, ath- letes serum CK activity kept the same in the nomal condition; when in the muscle hypertrophy in ihe stage of training and strength training, serum CK activity （ during the first week and the forth week ） was increased substantially compared with preparatory stage, all have significant difference （ P 〈 0.01 }, which indicates that strength is increasing, considering the training goal. With the subjects adapting themselves to the training intensity, the second and third week and the first week （ P 〈 0.05 }, the fifth week, the sixth week and the fourth week （ P d0.05） compared with CK activity gradually reducing, the results can explain the subjects can produce certain to adapt to the training intensity. In the strength endurance training phase, the seventh and eighth week＇s testing CK enzyme activity makes no significant difference （ P 〉0.05）, which can ex- plain the adaptation.
