Современные биологически активные компоненты спортивного питания. IX. Кофермент NAD для укрепления здоровья и повышения уровня спортивных достижений

Recent studies have shown that the use of biologically active substances by ordinary people and athletes, especially those that are natural components of the human body, can open up new ways for them to improve their health and take up their athletic performance on a new level. One of these compounds that is currently the subject of close attention from physiologists, sports medicine specialists and leading coaches is nicotinamide adenine dinucleotide (NAD). NAD is of natural origin and is present in virtually all living cells. From a chemical point of view, NAD is described as a coenzyme that ensures electron transfer during many biochemical oxidation-reduction reactions. It has now been established that NAD acts as a critical molecule in more than 500 reactions of cellular metabolism. The biological role of NAD in the body is directly related to human health and life expectancy. NAD molecules are involved in the production of bioenergy in the body and the implementation of its antioxidant protection. They regulate gene expression, promote restoration of DNA molecules after their damage, fight aging and reduce the risk of many age-associated diseases. After additional consuming of NAD, people also showed positive dynamics in terms of improved memory, increased concentration of attention and achieving of mental endurance. It was found that maintaining an adequate level of NAD in the body is one of the key factors for athletes to attain maximal athletic results. Based on the experimental data, the work provides evidence-based conclusion that athletes with increased NAD level in their body have increased physical strength, high endurance, resistance to physical and psychological stressors and have other positive athletic qualities. As a result, NAD can thus provide athletes with a noticeable competitive advantages over their rivals. The paper analyzes the safety issue regarding NAD consumption, considers the advantages and disadvantages of various methods of introducing NAD into the body, including methods of its intravenous infusion, and studies the issues of optimizing the dosage and timing of NAD depending on various factors. The main results of using fragments of the NAD molecule to increase its content in the body are also analyzed. The study concluded that NAD can be considered a powerful ally in the goal of ordinary people of high physical fitness and athletes to sport excellence.
