对25名男子排球运动员进行有氧训练、无氧训练和力量训练,分别测定运动后及恢复期血清酶和尿素氮。结果表明:1)力量训练和无氧训练引起CK活性变化明显大于长时间的有氧训练。2)无氧训练和力量训练后LDH呈现显著增高,而且运动前后具有统计学意义。3)三种训练应激后,血清GOT活性均有不同程度变化,其中有氧训练和力量训练较为明显,GOT升高可作为判断心肌疲劳程度的参考指标。4)无氧训练和力量训练后BU明显升高,并有非常显著差异,运动后24hBU均能恢复正常。表明BU可作为了解蛋白质分解代谢、机体随负荷和恢复状况一项简易可行的指标。
Twenty-five male volleyball players were subjected to aerobic training, anaerobic training and strength training. Serum enzyme and urea nitrogen were measured after exercise and during convalescence. The results showed that: 1) The changes of CK activity caused by strength training and anaerobic training were significantly greater than those of long-time aerobic training. 2) After anaerobic training and strength training LDH showed a significant increase, and before and after exercise with statistical significance. 3) The serum GOT activity of the three kinds of training stress changed in varying degrees. Among them, aerobic training and strength training were more obvious. Increasing GOT could be used as a reference index to judge the degree of myocardial fatigue. 4) After anaerobic training and strength training BU was significantly increased, and there is a very significant difference, 24hBU after exercise can return to normal. BU can be used as understanding of protein catabolism, the body with load and recovery status of a simple and feasible indicator.
