“…(Table 6). This result is different from that of other meta-analyses [52,53], but similar to several individual studies which did not meet the present eligibility criteria [54,55]. Two included studies [32,33] reported no improvement in sport performance, and we found that the experimental exercise in these two articles were more likely based on the ATP-CP system to obtain energy (Table 6).…”

Background The effects of sodium bicarbonate (NaHCO3) on anaerobic and aerobic capacity are commonly acknowledged as unclear due to the contrasting evidence thus, the present study analyzes the contribution of NaHCO3 to energy metabolism during exercise. Methods Following a search through five databases, 17 studies were found to meet the inclusion criteria. Meta-analyses of standardized mean differences (SMDs) were performed using a random-effects model to determine the effects of NaHCO3 supplementation on energy metabolism. Subgroup meta-analyses were conducted for the anaerobic-based exercise (assessed by changes in pH, bicarbonate ion [HCO3−], base excess [BE] and blood lactate [BLa]) vs. aerobic-based exercise (assessed by changes in oxygen uptake [VO2], carbon dioxide production [VCO2], partial pressure of oxygen [PO2] and partial pressure of carbon dioxide [PCO2]). Results The meta-analysis indicated that NaHCO3 ingestion improves pH (SMD = 1.38, 95% CI: 0.97 to 1.79, P < 0.001; I2 = 69%), HCO3− (SMD = 1.63, 95% CI: 1.10 to 2.17, P < 0.001; I2 = 80%), BE (SMD = 1.67, 95% CI: 1.16 to 2.19, P < 0.001, I2 = 77%), BLa (SMD = 0.72, 95% CI: 0.34 to 1.11, P < 0.001, I2 = 68%) and PCO2 (SMD = 0.51, 95% CI: 0.13 to 0.90, P = 0.009, I2 = 0%) but there were no differences between VO2, VCO2 and PO2 compared with the placebo condition. Conclusions This meta-analysis has found that the anaerobic metabolism system (AnMS), especially the glycolytic but not the oxidative system during exercise is affected by ingestion of NaHCO3. The ideal way is to ingest it is in a gelatin capsule in the acute mode and to use a dose of 0.3 g•kg− 1 body mass of NaHCO3 90 min before the exercise in which energy is supplied by the glycolytic system.

“…Therefore, considering the small effect observed, our results indicate that acute caffeine supplementation does not improve RSA in young soccer athletes. The result of the present study is also corroborated by meta-analysis studies [18,39] that did not find positive effects of caffeine in improving RSA performance or have indicated that this difference is very small (TE = 0.15), considered trivial for performance [40].…”

“…However, the effect of caffeine on high-intensity activities may be dependent on the type of test applied. Data from a recent meta-analysis demonstrated that acute caffeine ingestion did not improve performance in repeated sprints when evaluating the total work done over the sprints, the best sprint or the last sprint times [18]. It is important to highlight that in the referred meta-analysis, of the total of eight studies included, only three involved athletes of competitive level and no study included only soccer athletes.…”

Introdução: A cafeína é um recurso ergogênico amplamente utilizado em diferentes modalidades esportivas. No futebola habilidade de sprints repetidos é fundamental para o rendimento durante a competição, entretanto ainda não se tem clareza sobre os efeitos da cafeína na habilidade em questão. Objetivo: avaliar o efeito da ingestão aguda de cafeína no desempenho de sprints repetidos de jovens atletas de futebol. Métodos: Foram selecionados 13 atletas da categoria sub-20 de futebol. Os atletas ingeriram 5 mg/kg de cafeína ou placebo em um delineamento cruzado duplo cego. Uma hora após a ingestão os atletas foram submetidos ao teste de 6 sprints repetidos de 40 m com 20 segundos de descanso entre cada sprint. Cada tempo de sprint foi gravado utilizando o sistema de fotocélula. Para análise estatística foi utilizada ANOVA de medidas repetidas (2 x 6). Resultados: Foi encontrada diferença estatisticamente significativa para o fator tempo (p < 0,0001) indicando um aumento do tempo total gasto para completar o teste independente da condição (cafeína/placebo). Não foi encontrada diferença significativa para o fator condição (p = 0,66). Conclusão: No presente estudo a ingestão aguda de 5 mg/kg de cafeína não melhorou o desempenho na habilidade de sprints repetidos em atletas jovens de futebol.

“…A meta-analysis may help to overcome the low generalizability of findings from individual studies and clarify equivocal findings on a given topic. Even though several meta-analyses [2,[24][25][26][27][28] have explored the effects of acute sodium bicarbonate ingestion on various aspects of exercise performance (e.g., single and repeated sprint performance, intermittent exercise performance), none of these meta-analyses focused specifically on muscular strength or muscular endurance outcomes. Therefore, the objective of this study was to conduct a systematic review of studies examining the acute effects of sodium bicarbonate supplementation on muscular strength and endurance and to synthesize their results using a meta-analysis.…”

This meta-analysis found significant ergogenic effects of sodium bicarbonate supplementation on muscular endurance of both small and large muscle groups.2. No significant ergogenic effects of sodium bicarbonate were found for muscular strength.3. No significant linear trends in the effects of timing of sodium bicarbonate ingestion or acute increase in blood bicarbonate concentrations on muscular endurance or muscular strength were found.
