浅析运动强度对运动员血氨值的影响及相关研究

血氨作为一项新的运动生化检测指标已经广泛应用到体育实践中,尤其是在体育科学领域受到了广泛关注。针对我院20名足球专项运动员进行了两次不同运动强度的训练:短跑—400m全速跑;足球赛—90min的足球对抗赛。实验结果表明:运动员完成相应负荷运动后血氨值显著高于安静状态测值(P<0.01),表明其与运动强度的高度相关性。实验结果提示:血氨指标能够较精确地评价运动员的运动负荷强度、机体的机能状态、疲劳程度及恢复情况。

散打运动员不同运动强度血氨值变化的研究

对武汉体育学院散打代表队不同级别运动员在不同运动强度运动后的血氨值变化情况进行测定,结果显示受试者完成相应负荷运动后即刻至13min,血氨水平均显著高于运动前安静状态(P<0.01),显示血氨的应用能够较精确地评价运动负荷的强度、机体的机能状态、疲劳程度,表明了血氨作为生物学监测与评定指标的可靠性及其指导散打运动员进行科学训练的实践意义。

100例新生儿血氨值测定

为探讨新生儿高氨血症(NHA)的原因及高氨血症对新生儿行为能力的影响,我们对100例新生儿进行了血氨值测定。对象和方法采用微量扩散法(日本试剂)。

一种适宜于病生教学实验的改良血氨测定法

夏制急性肝损害时氨的毒性作用动物实验模型是病理生理教学实验的内容之一,已收录进全国病理生理实验指导,向各医学高校推荐。众所周知,在此实验中,血氨值的变化是其重要的指标。一些院校采用氨气敏电极测定仪快速检测血氨,但在实践中发现并不理想。因此,模索一种适宜病生教学实验的血氨测定方法势在必行。

Healthy ranges of serum alanine aminotransferase levels in Iranian blood donors

AIM: The healthy ranges for serum alanine aminotransferase(ALT) levels are less well studied. The aim of this study was to define the upper limit of normal (ULN) for serum ALT levels, and to assess factors associated with serum ALT activity in apparently healthy blood donors. METHODS: A total of 1 939 blood donors were included.ALT measurements were performed for all cases using the same laboratory method. Healthy ranges for ALT levels werecomputed from the population at the lowest risk for liver disease. Univariate and multivariate analyses were performed to evaluate associations between clinical factors and ALT levels.RESULTS: Serum ALT activity was independently associated with body mass index (BMI) and male gender, but not associated with age. Association of ALT with BMI was more prominent in males than in females. Upper limit of normal for non-overweight women (BMI of less than 25) was 34 U/L,and for non-overweight men was 40 U/L.CONCLUSION: Serum ALT is strongly associated with sex and BMI. The normal range of ALT should be defined for male and female separately.
