ABSTRACT
Park, K.S., Lee, W.L. The Change of Glutathione Peroxidase Concentration during the Progressive Maximal Exercise Test. Exercise Science, 11(1): 77-84, 2002. The purpose of this study was to investigate the change of plasma glutathione peroxidase(GPx) concentration during the progressive maximal exercise test and to identify whether there is a certain exercise intensity resulting in the high concentration of GPx. The subjects were 10 healthy graduate students(28.2±2.6yr) without any metabolic disease. In the 3 times pretest(treadmill running, Bruce protocol), the 50%, 60%, 70%, 80%, 90% and 100% of O2max were determined. In addition, the lactate threshold(LT) was analyzed during the pretest. In the head test, the concentration of plasma GPx were determined by ELISA(Enzyme-linked immunosorbent assay). After analysis, The mean and SD were determined by SPSS 8.0ver. and One-way ANOVA was applied as a statistic. The significance was .05. The results were shown that the LT(lactate threshold) was 65.8% of O2max. However, there was no significance in the change of plasma GPx concentration. Therefore, it seemed that the concentration of plasma GPx could not be changed by a certain exercise intensity during the progressive maximal exercise.
Key words: Plasma Glutathione peroxidase, LT(lactate threshold)
