THE ACID-BASE CHANGES IN HIGHLY QUALIFIED ORIENTER SPORTSMEN UNDER THE INFLUENCE OF GLUCOSE ELECTROLYTE DRINK WITH THE PLANT EXTRACTS ADDITION

Abstract

In real conditions of high-intensity training and competitive load of athletes, the most important for sports success is the preservation of energy metabolism indicators, and, in particular, the acid-base balance in the range of homeostatic normal values. One of the possible ways to maintain the acid-base balance of an athlete is the use of homeostatic electrolyte drinks, which can have a fairly rapid effect. In this regard, for our work we have identified the following goal of the study: to analyze the possibility of using the functional drink "Aluston" (FDA) produced by JSC "Alushta Essential Oil Plant" to maintain the acid-base balance of athletes and a possible increase in performance, training duration, resistance of athletes to long-term physical activity of high intensity. Methods: Stepwise loading protocol was used on a Kettler bicycle ergometer (Hmbq, Germany). Capillary blood sampling from athletes was carried out at rest before the start of the load and immediately after it was completed using an Epoc capillary (Epocal Inc., Canada). Biochemical parameters of blood like pH, concentration of CO2 and O2, [Na+], [К+], [Сa2+], [Cl–], [HCO3–], Lactate, Glucose, Crea, Hct, Hb, BE(ecf), BE(b ) were recorded by the Epocreader and Epochost analyzers (Epocal Inc., Canada). It was shown that FDA contributes to the stabilization of anion gaps, reduces the severity of the shift of the standard (BE-ecf) and true (BE-b) excess bases into the negative range, which can be regarded as a more pronounced preservation of the “strength” of blood buffer systems, and contributed to a decrease in tension in the pair acidosis-alkalosis. In addition, FDA supplementation likely shifts the phase of creatine fermentation to later loading stages. The last experimental fact requires further research, and also, modification changes in the composition, concentration ratio of active components in the “Aluston” drink remain relevant.
