Effects of Sodium Bicarbonate Supplementation in Martial Arts

The aim of this systematic review was to evaluate the effects of consuming sodium bicarbonate (NaHCO₃) and to gain insight into the nature of any changes in performance following NaHCO₃ supplementation among combat sport athletes. The analysis of the results provides compelling evidence in favor of acute or chronic NaHCO₃ supplementation as an ergogenic substance which could have an impact on several aspects of performance in judo [23, 31, 32], taekwondo [17, 20], karate [17, 33] [28, 29], wrestling [18, 19], jiu-jitsu [32] and boxing [16].

Acute or chronic NaHCO₃ supplementation is effective in the improvement of several variables of physical performance in combat sports during testing and simulated matches. Enhanced performance resulted in the increased capacity of the glycolytic system. However, the positive effects of its use are most often visible following the onset of fatigue. In addition, the use of NaHCO₃ is associated with an increased concentration of lactate in the blood. This systematic review provides data relevant for sports professionals and athletes alike regarding the use of NaHCO₃ as a supplement, prior or during training and matches.
