Oxidative stress is a characteristic phenomenon of the metabolism that can bring about a deterioration in the organism; it is related to the aging process, as well as to various degenerative illnesses and other health problems. There are studies which show that this phenomenon is inherent to vital processes in people and animals, and that under particular conditions it increases and its incidence is greater. The principal source of oxidative stress in humans is aerobic metabolism. Intense endurance sports, such as long-distance swimming, substantially increase energy requirements, resulting in a more intense metabolic activity and consequently increasing the production of substances which are potentially detrimental for the health of the sportsperson, known as free radicals or "ROS", Reactive Oxygen Species. It is important to know this process, and the necessary considerations to approach it, in order to improve the health and the performance of the long-distance swimmer. Today, useful nutritional strategies exist to combat the action of these substances and to avoid the problems associated to the increase in oxidative stress that these sportspeople are subjected to in the course of their sporting activities.
