摘    要:目的]对不同状态下血乳酸和血糖的变化和它们之间关系的研究,探讨血乳酸和血糖的测试在人体体质研究、运动中的能量代谢和运动能力研究中的应用价值.方法]用日本京都血糖和血乳酸测试仪,在运动员比赛前和比赛后进行血糖和血乳酸的测试,在运动场采指尖血.数据用MicrosoftExcel数据软件进行相关性和显著性分析.结果]①男大学生5000m竞赛后血糖和血乳酸显著相关(r=0.54,P<0.05);②800m和1500m比赛前血乳酸超过4mmol/L乳酸阈者占43%,5000m比赛前血乳酸超过4mmol/L乳酸阈者占75%.③比赛前运动员血乳酸平均值为4.9,标准差为3.19,波动在1.2至13.8mmol/L之间,波动幅度为12.6mmol/L,变异系数为65%;而比赛后血乳酸平均值为15.5,标准差为2.3,波动在9.8~20mmol/L之间,波动幅度为10.2mmol/L,变异系数为14.8%.结论]5000m长跑竞赛后血糖和血乳酸代谢显著相关,中、长跑竞赛前部分运动员血乳酸升高,竞赛后血乳酸代谢趋于一致.

关 键 词:血糖  血乳酸  中长跑  比赛前后

Abstract:Objective] The purpose of this study was to investegate the relationship between blood sugar and blood lactate before and after competition and their metabolism . Methods]The GLUCOCARDⅡGT-1620 and Lactate Pro Test Meter measure glucose and lactate at sports ground .Results] ①The glucose and lactate in the whole blood is significantly relationship after 5 000 meter competition;②The lactic acid in the whole blood over lactate threshold of 4 mmol is 45% and 75% before 800~1 500 meter race and 5 000 meter competition;③The lactic acid verage level is 4.9 and 15 .5 mmol,standard deviation is 3 .9 and 2.3 mmol,coeffient of variation is 65% and 14.8% respectively before and after competition.Conclusion] The glucose and lactate metabolites is significantly relationship after 5 000 meter long-distance race;The lactic acid metabolites after middle and long-distance running tend towards stability and reach unanimity.
Keywords:blood sugar  blood lactate  middle and long-running  before and after competition
