Nine normal young male students were studied during 2 days of relative rest, during 2 days of physical training and again during the succeeding 2 days of relative rest. Twenty-four hour urine collections showed that sodium and potassium excretion were lower during the exercise days, while urinary aldosterone excretion was increased. No differences in the 24-h urinary excretion of creatinine, calcium, and magnesium were found between the resting and exercise days. Hemoglobin concentration, hematocrit and red cell counts were decreased at 14 h and 42 h after exercise; these findings together with the increased serum bilirubin concentration could result from hemolysis. Plasma renin activity, angiotensin II and aldosterone concentration were increased 14 h after exercise but returned to baseline 42 h after exercise. Our data shows that one should take into account previous exercise when interpreting results of certain of these tests.
对9名正常年轻男性学生进行了研究，在2天的相对休息期间、2天的体育训练期间以及随后的2天相对休息期间分别进行观察。24小时尿液收集结果显示，运动期间钠和钾的排泄量较低，而尿醛固酮排泄量增加。在休息日和运动日之间，24小时尿肌酐、钙和镁的排泄量没有差异。运动后14小时和42小时血红蛋白浓度、血细胞比容和红细胞计数下降；这些发现以及血清胆红素浓度升高可能是溶血所致。运动后14小时血浆肾素活性、血管紧张素II和醛固酮浓度升高，但运动后42小时恢复至基线水平。我们的数据表明，在解释这些测试中的某些结果时，应考虑之前的运动情况。
