Description: The influence of dynamic and static load on the plasma level of myokines in strength-and endurance-trained athletes and untrained subjects has been studied. The range of myokines has been found to depend on the type of loads and the level of fitness. Dynamic and static exercises have different effects on the level of myokines in athletes and untrained subjects. The dynamic load increases the level of IL-6 and IL-8 in the plasma of athletes, while the static load increases the concentration of IL-15 and LIF. At the same time, no increase in the level of IL-8 after cyclic loading or in IL-15 after a static load has been observed in the control group. These differences may be based on a number of mechanisms. The cellular composition of skeletal muscles and the phenotypic features of muscle fibers, changing as a result of regular exercise, can modify the processes of myokine production. However, the processes of transcription in muscle fibers are much more important; the most important ones are HIF-1α, [Ca2+]i and [Na+]i/[K+]i-dependent intracellular signaling pathways. The modification of these mechanisms caused by different physical loads and intensity is of great interest since it is a promising way to influence the metabolic processes at the cellular and systemic levels, which is very helpful in both improving athletic performance and correcting metabolic disorders in a number of socially significant diseases.
