【摘要】 利用i-STAT血气分析仪检测12匹伊犁马1000m速步训练赛静息、热身后及赛后即刻、15min、30min、60min时静脉血中的血气指标,并对各血气指标的差异性和相关性进行统计分析。结果表明,运动前后静脉血中PvCO2、PvO2、HCO3、TCO2、SvO2和Glu变化差异不显著(P>0.05)。血液pH、BE和Ca2+在赛后即刻均明显降低,但经15min休息后都基本回升到静息水平;K+、Hct和Hb在赛后即刻均显著增加(P<0.05),但经15min休息后都基本回降到静息水平。血液pH与BE、HCO3呈极显著正相关(P<0.01),与TCO2浓度呈显著正相关(P<0.05),Hct、Hb与pH和HCO3呈极显著负相关(P<0.01),与K+呈极显著正相关(P<0.01)。因此,BE、HCO3、TCO2、Hct和Hb对酸碱平衡均有一定的调节作用;Na+、K+和Ca2+对机体运动具有一定的调节作用。更多还原

【Abstract】 Blood gas index in venous blood of 12 Yili horses in different stages of 1000 mtrot training(motionless,after the warming up,after the game instantly,15 min,30min,60min)were detected by i-STAT blood gas analyzer,and the differences and correlation of the blood gas index were analyzed.The results showed that before and after exercise PvCO2,PvO2,HCO3,TCO2,SvO2 and Glu of the venous blood did not change significantly(P>0.05).Blood pH,BE and Ca2+were lower immediately after the game,but after 15 min rest basic rebounded to motionless level.K+,Hct and Hb immediately after the game were significantly increased(P<0.05),but after 15 min rest basic back down to motionless levels.Blood pH value was highly significant positive correlation with BE and HCO3(P<0.01),and significantly positive correlation with the TCO2concentration(P<0.05),Hct,Hb were highly significant negative correlation with pH,HCO3(P<0.01),Hct,Hb were highly significant positive correlation with K+(P<0.01).The analysis showed that BE,HCO3,TCO2,Hct and Hb on acid-base balance all had certain adjustment,Na+,K+and Ca2+on the body movement had certain adjustment.更多还原
