  Uma das principais causas da fadiga muscular decorrente de esforço é o aumento da concentração de hidrogênio no meio intracelular, acidificando-o e, consequentemente, influenciando negativamente na performance. A literatura científica diz que a suplementação de bicarbonato de sódio é capaz de atenuar o desequilíbrio do pH na prática esportiva, diminuindo a fadiga e melhorando o desempenho. O presente estudo buscou avaliar os efeitos da suplementação de bicarbonato de sódio no desempenho de praticantes de musculação. Os participantes receberam a suplementação contendo 0,3 g/kg de massa corporal de bicarbonato de sódio e foram submetidos ao treinamento. Analisou-se o lactato sanguíneo e a percepção subjetiva de esforço em dois momentos: sem a suplementação e com a suplementação. Os níveis de lactato sanguíneo aumentaram em todos os participantes, e a maioria relatou redução na percepção subjetiva de esforço. A suplementação de bicarbonato de sódio se mostrou eficaz em melhorar o desempenho físico na amostra avaliada.  ABSTRACT Sodium bicarbonate supplementation in musculation practicersOne of the main causes of muscular fatigue due to exertion is the increase of the hydrogen concentration in the intracellular environment, acidifying it and, consequently, negatively influencing the performance. The scientific literature says that sodium bicarbonate supplementation is able to attenuate pH unbalance in sports practice, reducing fatigue and improving performances. The present study aimed to evaluate the effects of sodium bicarbonate supplementation on the performance of bodybuilders. All of the participants took supplementation containing 0.3g · kg-1 body weight of sodium bicarbonate and underwent training. Blood lactate and subjective perception exertion were analyzed in two moments: without supplementation and with supplementation. The blood lactate levels increased in all participants, and most of them reported a reduction in the subjective perception exertion. Sodium bicarbonate supplementation was shown to be effective in improving physical performance in the sample evaluated.
