Efficiency of using a range of biologically active additives for middle distance runners

Abstract

Significant intensification of metabolism in the body of athletes requires additional consumption of ergogenic agents, as the lack of vitamins, minerals, carbohydrates and proteins adversely affects the performance of athletes. The best way out of this problem is to use dietary supplements. Protein, amino acids and their derivatives belong to them. Disruption of the amino acid ratio or the absence of at least one of the essential amino acids leads to inhibition of protein synthesis and other abnormalities in metabolism, which reduces physical performance. Therefore, the relevance of research into the erogenous properties of amino acids for future use in sports practice is obvious. Objective: To identify the metabolic effects of the use of the amino acid complex on the performance of middle-distance runners, body composition and antioxidant properties. Results. The complex of biologically active additives has influenced the state of the antioxidant system of athletes, which is associated with a positive effect on the catalase link and membranes of erythrocytes. The complex of amino acids also stimulates the reduction of malonic dialdehyde content, which indicates the state of the body's pro - and antioxidant balance. This effect could have caused both the complex under study as a whole and its individual components, the antioxidant activity of which was shown in previous studies. This is especially true for Ν-acetylcysteine, glutamine, branched-chain amino acids, vitamin B6, which regulate the synthesis of tryptophan in the body. The latter can block the production of cortisol, an anti-catabolic hormone, inhibit the development of fatigue, affect the glutathione system and cause other changes that, in the aggregate, give an overall positive metabolic effect. Conclusions. The use of a complex of biologically active additives for athletes for three weeks, as an additional means of increasing physical performance, has a positive effect on the component composition of the body weight of athletes, oxygen-transport function of the blood, energy efficiency of energy supply, as well as the state of the AO-system, which provides versatile regulators metabolism may result in increased physical performance and accelerated recovery of athletes.The latter allows us to recommend a complex of biologically active supplements for use against the background of the training process and competitive activity of middle distance runners in order to correct metabolism and achieve ergogenic effect.
