摘　　要：14名大学生运动员在功率车上分别进行一次急性有氧或无氧运动,并在有氧或无氧运动前后抽取静脉血以测定血浆丙二醛(MDA)、红细胞丙二醛、红细胞超氧化物歧化酶(SOD)和红细胞谷胱甘肽过氧化物酶(GSH-Px)。结果显示,有氧运动后即刻红细胞MDA含量显著增高,红细胞GSH-Px活力显著增强;无氧运动后即刻血浆及红细胞MDA含量均无显著改变,但红细胞SOD和红细胞GSH-Px的活力都呈显著性增高。提示急性有氧或无氧运动都对人体内的自由基代谢具有重要影响。The plasma MDA, RBC MDA and RBC SOD and GSH-Px of 14 athletes from university were measuredboth at rest and after exercise (anaerobic and aerobic) on ergometer. The results indicated that the plasmaMDA content was influenced by neither anaerobic nor aerobic exercise, but the RBC MDA content increasedsignificantly after aerobic exercise. The RBC SOD activity increased only after anaerobic exercise, while theGSH-Px activity increased both after anaerobic and after aerobic exercise.
