|EFFECT OF PHYSICAL ACTIVITY ON OXIDATIVE STRESS: A REVIEW OF IMPACT AND IMPLICATION AFTER TRAINING|
|Physical Activity, Oxidative Stress, MDA, Vitamin C|
This paper discusses the scientific evidence that has been collected regarding the influence of physical activity on oxidative stress. One of the body's responses to exercise or physical activity is increased levels of free radicals. Physical activity can increase the formation of free radicals in the body thereby increasing oxidative stress. Oxidative stress is a condition that occurs because of an imbalance between the production of free radicals with antioxidant defense systems in the body. MDA (Malondialdehyde) is one of the indicators used to determine oxidative stress in humans. MDA is the result of lipid peroxidation in the body due to free radicals. Increased conditions of oxidative stress have implications for muscle damage and if it lasts in the long run will lead to various diseases such as hypertension, atherosclerosis, diabetes, heart failure, stroke, and other chronic diseases. It is recommended that the understanding of this should be understood by all sports actors, both trainers, builders, and athletes themselves that will be useful to reduce the negative impact of physical activity so that positive impact or sports achievement will increase. To reduce the negative impact of oxidative stress it is necessary to minimize one of them by taking antioxidants after physical activity. Consuming antioxidants in this form of vitamin C proven to reduce the occurrence of oxidative stress. Vitamin C easily scavenges free radicals and thus can prevent oxidative damage to important biological macromolecules. Vitamin C supplementation can suppress lipid peroxidation during exercise so as to reduce oxidative stress.
