The Difference of Superoxide Dismutase (SOD) Level after Consuming Red Guava Juice (Psidium Guajava L. Red Cultivar) During Aerobic Exercise for the Beginner

Abstract

Aerobic exercise for the beginner causes overly muscle contraction and the use of occasionally used muscle, so that additional unit motor recruitment is needed. Consequently, metabolism inside the body increases. If the antioxidant inside the body is not enough, oxidative stress will occur. Antioxidant is needed to prevent the occurrence of oxidative stress. The design of this research was experimental-nonrandomized pre-post test control group design. The subjects of the research were divided into 2 groups, i.e. the red guava juice and mineral water groups. Both groups performed aerobic exercise for 30 minutes every day for 27 days. Blood samples were taken for measuring superoxide dismutase (SOD) level. Ttest and repeated anova test were used for data analysis. T-test and repeated anova analysis amount of SOD level showed that there was no difference between red guava juice group and mineral water group (p>0,05). There was a decrease in the amount of SOD level for the beginners during aerobic exercise, but statistically it was not significantly different between the group which consumed red guava juice and the group which consumed water.
