Abstract

The purpose of this study was designed to examine activation of antioxidant enzymes and concentration of malondialdehyde(MDA) and total antioxidant status(TAS) in athetics. For this purpose, baseball, ice-hockey and taekwondo players were picked up to be tested to a treadmill running from rest until their entire physical exhaustion. Subject` blood was collected before, immediately after, 10 and 30 minutes after the exercise to be examined. The results of this study can be summarized as follows; 1. It was found out that the activation of superoxide dismutase(SOD) could be changed on different phases : before and immediately after exercise, and recovery of exercise. However, there was found no significant difference of the activation depending on the length of elapsed time.As a result of the one-way ANOVA, it was found that there was no significant difference of SOD activation among groups before, immediately after and recovery 10 and 30 minutes after the exercise. 2. It was found out that the activation of catalase(CAT) could be changed on different phases : before and immediately after exercise, and recovery of exercise. However, there was found no significant difference of the activation depending on the length of elapsed time. As a result of the one-way ANOVA, it was found that there was no significant difference of CAT activation among groups before, immediately after and recovery 10 and 30 minutes after the exercise. 3. It was found out that the concentration of MDA could be changed on different phases : before and immediately after exercises, and recovery of exercise. However, there was found no significant difference of the concentration depending on the length of elapsed time. As a result of the one-way ANOVA, it was found that the baseball players group signification showed the highest concentration immediately after exercise. 4. It was found out that the concentration of TAS could be changed on different phases : before and immediately after exercise, and recovery of exercise. However, there was found no significant difference of the concentration depending on the length of elapsed time. As a result of the one-way ANOVA, it was found that taekwondo and ice-hockey player groups showed significantly lower concentration then baseball players group immediately after exercise. We conclusion that immediately after exercise, Taekwondo, Ice-hockey and baseball player, increased TAS, MDA, and CAT. But those gradually decreased to baseline at recovery phras and antioxidant enzyme depend on exercise type and exercise intensity.
