CK、心率等生理生化指标在篮球运动员比赛前后的监控研究.docVIP

篮球运动员比赛前后部分生理生化指标的监控研究 王艳琼1 杨栋林2 谭周荣3 廖慧萍1 (1广西师范大学体育学院,2广西师范大学生命科学院, 广西，桂林 541004 3广西体育局江南训练基地 广西南宁 530031) 摘要：以血清肌酸激酶(CK)、乳酸脱氢酶(LDH)、心率(HR)、肺活量(VC)为生理生化指标，对篮球运动员在篮球比赛前后所出现的一系列变化做测定，结果发现：血清CK酶活性均有所升高； LDH酶活性随着比赛的进行呈现增加趋势，且赛后即刻达到最高值；心率在比赛结束后即刻，也出现了最大化现象；肺活量反而最低。表明所选定生理生化指标可以对比赛过程中的运动量、强度以及赛后的恢复等情况做出科学的评定，而且生理生化指标联合运用使运动训练或比赛的监控更具有可靠性。 关键词：篮球运动员；运动训练；肌酸激酶；乳酸脱氢酶 A Study on Physiological and Biochemical Index Monitoring of Basketball Player before and after the Match Wang Yan-qiong1 Yang Dong-lin2 Tan zhou-rong3 (1.

Which indicate that the physiological biochemistry index which selected can make the scientific evaluation of the situation such as exercise load and exercise intensity in the match and recovery after the match, and union utilization of the physiological and biochemistry index can make the monitoring more reliability of sport training and match.
