Pengaruh Pemberian Vitamin E Terhadap Derajat Stress Oksidatif Akibat Olahraga

Abstract

Sports may have both good and bad consequences. Sports have a good influence on fitness and health, performance, and the prevention of many ailments. The development of oxidant chemicals, which initiate oxidative stress events, is one of the unfavorable impacts of exercise. The body's antioxidant defense mechanism is unable to keep up with the generation of free radicals, resulting in oxidative stress. SOD (oxidative stress) and MDA (malondialdehyde) are biological indicators in organisms that are under oxidative stress from free radicals. Vitamin E is an exogenous antioxidant that contains a variety of antioxidant components. The purpose of this study is to see what influence administering vitamin E before exercise has on plasma malondialdehyde levels and the degree of SOD oxidative stress damage in individuals after exercise. The experimental laboratory post test control group design was utilized in the research, with three groups consisting of nine persons each. Before and after doing submaximal intensity physical exercise, 3cc of blood was collected.The results of the post hoc test revealed a significant difference (0.001) between the control and K1 treatment groups (250 mg vitamin E dosage). The difference between the control and K2 therapy groups (500 mg vitamin E dosage) was statistically significant (0.000). The K1 (250 mg vitamin E) and K2 (500 mg vitamin E) treatment groups differed significantly (0.006). According to the findings of this study, taking exogenous antioxidants (250 mg and 500 mg of vitamin E) before physical exercise for seven days can lower plasma SOD and MDA levels.
