Mechanisms of Antioxidant’s Action on the Physical Performance of Athletes

Abstract

The goalsystematization of data on the mechanisms of natural antioxidant's action on metabolic bases of formation stimulation of physical performance of athletes. Methods. An analysis of the data of scientific and methodical literature and Internet.

Estimation of Adenosine Triphosphate Based Preparation Influence on Work Capacity during Modelling Of Intensive Continuous Physical Loads / Adenozintrifosfato ir mineralinių medžiagų mišinio įtaka eksperimentinių gyvūnų darbingumui atliekant didelės apimties ir intensyvumo krūvius

“…The results of determining pH, which usually decreases in the dynamics of cyclic character loads (running, swimming, etc.) due to lactate accumulation in circulatory bed (Fleming et al, 2017;Rozenfeld, Ryamova, 2016) and oxidative stress (Gunina, Milašius, 2016;Patlar et al, 2016), have demonstrated that pH value under the impact of continuous loads as compared to the data of intact rats not only failed to decrease, but rather increased slightly (by 0.011) and significantly (p < 0.05) as compared to the control data and reached the value of 7.446, thus, indicating the tendency to metabolic acidosis development. Significant changes of pH, during modelling running loads in the face of ATPlong administration, were not observed as compared to data of intact animals.…”

“…Therefore, permanent intensive physical loads necessitate systematic and substantiated application of cardioprotective means for protection of the myocardium (Gunina, Milašius, 2016). However, many pharmacological preparations, widely used in clinical cardiological practice, and all trimetazidine and meldonium based drugs in particular, are not allowed to be used in elite sport due to their prohibition by the WADA that has come into force by 2015-2016 (Prohibited List, 2017; Gunina, Kostenko, 2016).…”
