beta-alanine — no detected effect on rating of perceived exertion
ModerateEvidence strength: moderate. Human evidence with one recorded weakness, or capped at moderate by its design or by unread numbers.FindingNull result“The meta-analysis showed that BA supplementation generated a trivial and non-significant effect on RPE (SMD, 0.03; 95% CI −0.52–0.58; p = 0.92), and low heterogeneity was observed in the studies (I2 = 42%; p = 0.14).”

beta-alanine — no detected effect on time to exhaustion
ModerateEvidence strength: moderate. Human evidence with one recorded weakness, or capped at moderate by its design or by unread numbers.FindingNull result“Figure 6 shows that BA supplementation generated a small and non-significant effect for time on the TTE test (SMD, 0.25; 95% CI −0.01–0.51; p = 0.06).”
