Table 4 Effects of sodium bicarbonate supplementation on exercise performance: summary findings, methodological quality of literature reviews, and quality of evidence

From: Effects of sodium bicarbonate supplementation on exercise performance: an umbrella review

Quality of evidence Methodological quality of literature reviews
Moderate High
Meta-analyses that found significant ergogenic effects of sodium bicarbonate
 Low • Endurance events lasting 45 s to 8 min in Christensen et al. [14]
• Anaerobic power in the Wingate test using the multiple-day supplementation protocol in Lopes-Silva et al. [19]
• 2000-m rowing in Turnes et al. [20]
• Muscle endurance in Grgic et al. [17]
 Moderate • Anaerobic power in the repeated-bout Wingate test in Grgic [15] • Yo-Yo test performance in Grgic et al. [16]
Meta-analyses that did not find significant ergogenic effects of sodium bicarbonate
 Low • General mean power in Carr et al. [13]
• Repeated-sprint ability (total work) in Lopes-Silva et al. [18]
• Anaerobic power in the Wingate test using single-dose supplementation protocol in Lopes-Silva et al. [19]
/
 Moderate • Repeated-sprint ability (best sprint) in Lopes-Silva et al. [18]
• Repeated-sprint ability (last sprint) in Lopes-Silva et al. [18]
• Muscle strength in Grgic et al. [17]
