The combined effect of low-level laser therapy and dietary supplements at the microcirculation system in athletes

Abstract

The problem of athletes’ body resistance to effects of extreme loadings which lead to decreased adaptive capabilities of the body and over training is particularly relevant in modern sports. In order to improve the physical performance of athletes, there is a constant search for new  tools and methods.  Aim: to study the effect of dietary supplements at the microcirculation system, both in isolated use and in combination with low-level laser therapy.  Material and methods. The study included 28 highly qualififi ed male all-around athletes of the CMC and MS levels. To study the parameters  of skin microcirculation, laser Doppler flfl owmetry (LDF) was used, device “LAKK-02” (NPP “LAZMA”). The following parameter was calculated:  microcirculation index (MI) proportional to the number of red blood cells in the diagnosed volume and their average velocity. The received  signal give the information about endothelial, neurogenic and myogenic active mechanisms of vascular tone regulation and passive mechanisms – respiratory and cardiac flfl uctuations in blood flfl ow; flfl ax index, specififi c oxygen consumption index by tissues, erythrocyte concentration  index in the probed blood volume and the ratio of coenzymes of reduced nicotinamide adenine dinucleotide (NADH) and oxidized flfl avinadenine  dinucleotide (FAD) (NADH/FAD).  Results. After isolated use of dietary supplements, the level of perfusion increases signififi cantly by 48 % (p < 0.05), and the value of the flfl ax  increases by 78 % (p < 0.05). More red blood cells by 22 % (p < 0.05) are released from blood depots into the microcirculatory bed. The tone  of arterioles decreases by 48 % (p < 0.05), of precapillary sphincters – by 59 % (p < 0.05). In mitochondria, ratio of NADH/FAD coenzymes  increases by 55 % (p < 0.05).  Conclusion. Laser radiation in combination with dietary supplements optimizes recovery processes in the body of athletes who are subjected  to heavy physical exertion. Under the combined effect, the intensity of microcirculation increases, oxygen output of erythrocytes by hemoglobin  improves as well as its active diffusion from blood into tissues and participation in the ATP synthesis at the level of cell mitochondrial. It is worth  noting that there is similarity in the isolated use of dietary supplements and in combination with low-energy laser radiation which enhances  the mechanism of action of dietary supplements.
