Abstract

The purpose of this study was to determine the differences of the influence of submaximal exercise in the morning and afternoon sessions on the degree of oxidative stress. The research design was experimental laboratories research with the pretest and posttest design. The subjects of this research were 8 people aged 21 - 25 years and given submaximal physical exercises that group 1 for morning sessions and group ll for the afternoon sessions. Physical exercises in this study submaximal physical exercises by pedaling an ergocycle Technogym bike by using 80% HR max for 6 minutes. The measurement of plasma MDA levels with TBA (thiobarbituric acid) methods with units of nmollml. While the measurement of the activity of SOD erythrosyte enzyme. The data obtained were analyzed by descriptive statistic, normality test, paired sample test, and independent sample test with significant level of0.05. From the analysis, the differences in the plasma MDA levels posttest in the group exercise morning and afternoon had value p = 0.002 (p < 0.05) means these was a significant differences on the plasma MDA levels after submaximal exercise in the morning and afternoon sessions. The differences of the activity of SOD erythrocyte enzyme posttest the group exercise morning and afternoon had value p = 0.128 ( p > 0.05) meaned there was no significance difference on the activity of SOD erythrocyte enzyme after submaximal physical exercise in the morning and afternoon sesstons. The conclusion of this research is the difference of influence of influence of submaximal physical training at morning and afternoon session to the plasma MDA level have its difference, ant the difference of influence of submaximal physical training at morning and afternoon session to the erythrocyte SOD enzyme activity have not its difference.
