摘　　要：目的观察业余选手在马拉松比赛前后血糖、血乳酸、血液酸碱度和血尿素的变化。方法 50名选手赛前1h和赛后即刻经动脉和静脉采血测血糖、血乳酸、血气和血尿素等项目进行比较分析。结果血糖和pH赛前赛后无明显变化而血乳酸和血尿素赛后明显增高,差异有统计学意义(P<0.01)。结论赛后血乳酸明显增高且1/3选手达到无氧阈4mmol/L以上,但血糖维持正常提示肝糖原异生功能良好。虽有乳酸增高,但pH正常,说明机体处于良好的代偿状态;血尿素和乳酸同时显著增高提示马拉松赛对少数选手运动量过大,应防止疲劳过度而造成伤害。Objective To observe and analyze the amateurs＇ blood sugar,lactic acid,pH and carbamide during marathon.Methods Fifty amateurs were enrolled to be collected blood one hour earlier before the beginning of the match.Their blood sugar,lactic acid,pH and carbamide were analyzed,and then compared with that after the match.Results All the 50 players＇ blood sugar and pH were not different from before.The blood lactic acid and carbamide were obviously increased when compared with before（P〈0.01）.Conclusion It is showed that one third players＇ blood lactic acid increases to more than 4 mmol/L during marathon.The blood sugar is normal suggests the liver hepatin is created normally.Although the blood lactic acid is increased,the pH is normal,which shows that the body＇s function is done well.The abnormal results suggest that there are many dangers to the amateurs.It reminds the amateurs of doing exercises according to their abilities before match.
