The occurrence of possible prolonged alterations in plasma levels of cortisol, epinephrine, norepinephrine, selected energy metabolites, and water and electrolyte balance was assessed in six highly trained male marathon runners by measuring blood biochemical constituents on the 10th day before and for the three days following the running of a marathon. Post-race changes in hemoglobin, hematocrit, and protein levels indicated that a hemodilution had occurred, possibly as a result of elevated sodium levels. Epinephrine remained elevated until the second day. Cortisol was depressed on the first and third post-race days while variable levels were observed on the second day. No prolonged alterations were noted in norepinephrine, FFA, glycerol, triglycerides, glucose, lactate, and pyruvate.
通过在马拉松比赛前10天以及比赛后的三天测量血液生化成分，评估了六名训练有素的男性马拉松运动员血浆中皮质醇、肾上腺素、去甲肾上腺素、特定能量代谢物以及水和电解质平衡可能出现的长期变化。赛后血红蛋白、血细胞比容和蛋白质水平的变化表明发生了血液稀释，这可能是钠水平升高的结果。肾上腺素在第二天之前一直保持升高。皮质醇在赛后第一天和第三天降低，而第二天观察到其水平变化不定。去甲肾上腺素、游离脂肪酸、甘油、甘油三酯、葡萄糖、乳酸和丙酮酸没有出现长期变化。
