“…Although these effects on performance might appear small, they are of considerable significance to the athlete, for whom an improvement of even a fraction of a second in these events is considered to be a major achievement. In a study by VanMontfoort et al [10], ingestion of sodium bicarbonate was found to increase the sprint performance in elite male athletes compared to citrate, lactate and chloride ingestion.…”

“…This in turn could delay the onset of fatigue [8]. Studies [9,10] have confirmed that increased extracellular pH and higher bicarbonate raise the H + and lactic acid efflux from active muscles. This is due to an increase in the activity of the Lactic acid/H + co-transporter, which becomes more active as the intracellular/extracellular H + gradient increases, during contraction as well as during recovery.…”

“…Por outro lado, Slaler et al 55 não encontraram mudança na força nem na composição corporal de atletas, adultos jovens, sob treino de resistência após a suplementação oral de betahidroximetilbutirato na dose deum aumento no pH plasmático, o qual leva a um atraso no início da acidificação intracelular durante o exercício. Van Montfoort et al 57 , num estudo duplo-cego randomizado com 15 corredores, concluíram que o bicarbonato é mais benéfico em aumentar o desempenho do que placebo ou outros agentes tampões.…”

Objective: To review the use, benefits and adverse effects of the main dietary supplements consumed by adolescents. Sources:The literature review was performed using MEDLINE and LILACS databases (1997-2008). We analyzed 377 articles, and 52 of them were selected as references. Summary of the findings:Consumption of dietary supplements is widely spread among adolescents. This habit has often been detected in pediatric and adolescent medicine clinics. Most of the time, the use of supplements is motivated by the search of the "ideal body." Other reasons for this practice are: attempt to compensate for an inadequate diet, increase immunity, prevent diseases, improve athletic performance and overcome their own athletic limits. The dietary supplements most frequently used and for which there is little evidence of beneficial effects in healthy adolescents are: proteins, amino acids, beta-hydroxy-betamethylbutyrate, microelements, carnitine, creatine, vitamins, caffeine, and bicarbonate. This dietary supplementation may be beneficial for competitive athletes who do not have a balanced diet after a specific dietary deficiency has been detected. Conclusion:The unrestrained consumption of dietary supplements should be avoided, since, besides the lack of evidence that such practice will lead to improvement of performance, it exposes adolescents to several adverse effects. Balanced nutrition, with intake of essential energy and nutrients is usually enough to achieve good athletic performance. The use of dietary supplements must be allowed only for selected cases in which specific nutritional deficiencies are identified.

ResumoObjetivo: Revisar crititcamente o uso, benefícios e efeitos adversos dos principais suplementos alimentares utilizados por adolescentes. Fontes dos dados:A pesquisa bibliográfica, realizada nos últimos 10 anos, utilizou os bancos de dados MEDLINE e LILACS. Foram examinados 377 artigos, sendo selecionados 52. Síntese dos dados:O consumo de suplementos dietéticos é amplamente difundido entre adolescentes. Tal fato é constatado, com frequência, nos consultórios de pediatria e hebeatria. Na maioria das vezes ele ocorre sem uma necessidade específica, sendo motivado pela busca do corpo ideal. Outros motivos para essa suplementação são: compensar dieta inadequada, aumentar imunidade, prevenir doenças, melhorar o desempenho competitivo e superar os próprios limites. Os suplementos alimentares mais utilizados e discutidos nesse artigo e para os quais existem poucas evidências de um efeito benéfico de sua utilização por adolescentes saudáveis são: proteínas, aminoácidos, betahidroxibetametilbutirato, microelementos, carnitina, creatina, vitaminas, cafeína e bicarbonato.Conclusão: O uso irrestrito de suplementos dietéticos deve ser desaconselhado, uma vez que expõe o adolescente a vários efeitos adversos, além da falta de evidência de que tal prática levará a melhora no desempenho. Uma nutrição balanceada, com aquisição...

“…These decrements in performance can also be related to the accumulation of metabolites during exercise such as hydrogen ions resulting from increased lactic acid formation in high intensity exercise (44). Creatine monohydrate, and sodium bicarbonate, are two widely-studied ergogenic aids that have shown to attenuate the decline in fatigue while also increasing power output in high intensity exercise bouts such as sprinting (1,3,4,7,8,11,12,16,31,32,55,65,68).…”

“…Current research has shown that ingesting sodium bicarbonate may enhance aspects of sprint performance such as power output, total anaerobic work, and delaying fatigue (7,8,32,38,39,40,41,42,65). Lavender and Bird (1989), and Bishop et al (2004Bishop et al ( -2005, concluded that sodium bicarbonate supplementation improved power output levels in repeated sprints.…”

The Effects of a Combined Supplementation of Creatine and Sodium Bicarbonate on Repeated Sprint Performance James Jeremy BarberThere is well-established research that suggests both creatine and sodium bicarbonate are effective ergogenic aids. However, only one published study has examined the combined effects of creatine and sodium bicarbonate. The primary purpose of this study was to determine if a combined supplementation of creatine monohydrate and sodium bicarbonate would further enhance the well-documented effects of creatine supplementation alone on repeated sprint performance. Thirteen healthy and fit males (Mean age = 21.15 ± 0.65 years and mean VO2 max = 66.72 ± 5.78) participated in this experimental study using a double-blinded crossover study design in which each subject was used as his own control. All subjects completed 3 conditions, followed by a 3-week washout period between each condition: 1) Placebo (Pl; 5 g maltodextrin + 0.5 g/kg maltodextrin), 2) Creatine (Cr; 5 g + 0.5 g/kg maltodextrin), and 3) Creatine plus sodium bicarbonate (Cr+Sb; 5g + 0.5 g/kg sodium bicarbonate). Each condition was a 2-day supplementation. In the morning after each supplementation, peak power, RPP, mean power, RMP, fatigue index, and perceptions of fatigue and GI distress were assessed during six 10-second repeated Wingate tests. Blood bicarbonate, pH, and lactate were measured 5 minutes before testing and immediately after the last Wingate sprint.The main findings were; 1) Cr+Sb produced 7% greater relative peak power and 4.6% greater peak power values than placebo, and 2) Cr+Sb demonstrated the greatest attenuation of decline in relative peak power over six repeated sprints. However, in contrast to our hypotheses, v no benefits from either supplementation were observed for relative mean power, fatigue index, and perception of fatigue. Considering that this current study found benefits from combining creatine and sodium bicarbonate, it suggests that combining the supplements may improve repeated sprint performance. Future research on a greater sample size, a specific athletic population, various exercise modes, and comparing results with a sodium bicarbonate alone supplementation would be beneficial in determining if this combined supplementation is worthwhile.vi

Effects of Ingestion of Bicarbonate, Citrate, Lactate, and Chloride on Sprint Running

Abstract: Bicarbonate is possibly more beneficial to sprint performance than lactate and probably more beneficial than citrate or chloride. We recommend ingestion of sodium bicarbonate to enhance sprint performance.
