Abstract:
The purpose of this study was to research the characteristic of superoxide dismutase (SOD) in erythrocy-tes of sprinters and middle-distance runners. Resting content and activity of SOD in erythrocytes were studi-ed in 8 untrained men, 8 sprinters and 8 middle-distance runners (male). SOD content, as well as SODactivity, in athletes was significantly greater than it in untrained men. It suggested: the exercise trainingwhich glycogen breakdown provided the majority of the non-oxidative energy could elevate the level of SODin erythrocytes. The VO_2 max and AT, and SOD content and activity in erythrocytes from 12 athletes (4sprinters and 8 middle-distance runners) were studied. There was no significant correlation between both VO_2max and AT and SOD level. To also observe the change of SOD in erythrocytes after a bout of exercise.The content and activity of SOD did not change significantly after 12 athletes exercised to VO_2max on acycle ergometer. Similarly, they did not change significantly during 14 hours of recovery from 5000-metrerace. These athletes had trained regularly several years and SOD level in erythrocytes of them had increased,which had been sufficient to remove and cope with increaced O_2 during the exercise. It might be one ofthe causes that SOD in erythrocytes did not change significantly after a bout of exercise.
