Mechanisms of action and ergogenic effects associated with NaHCO3 supplementation in physical exercise: a narrative review
Abstract
In exercises where the anaerobic system predominates, there is an accumulation of H+ ions, which generates an acid-base imbalance through changes in pH, impacting fatigue levels and generating metabolic acidosis. Supplementation with NaHCO3 can mitigate the effects of fatigue and optimize performance in activities and/or sports with a predominance of the anaerobic system. Therefore, the present study aimed to carry out a narrative review, in order to elucidate and update knowledge about NaHCO3 supplementation. The review in question was carried out through searches in the PubMed, Web of Science and Google Scholar databases, without date restrictions, using the terms “Sodium Bicarbonate Supplementation”, “NaHCO3” and “Alkalosis” or the same in Portuguese. Scientific articles, master's dissertations and doctoral theses, in English and Portuguese, were considered. It is concluded that supplementation with NaHCO3 plays a fundamental role in physiological processes related to anaerobic metabolism, mainly about reducing acidosis and delaying the onset of fatigue. However, for supplementation to have ergogenic effects, a series of precautions must be taken, especially in relation to the quantity, form and timing of intake. In addition to considering the type of modality and the individuality of the subjects. Finally, when using NaHCO3 in a practical context, it is recommended that the supplementation be tested, preferably away from competition periods.
