Caffeine Endurance Performance Meta-AnalysisNo evidence of publication bias was detected where assessable, although some subgroup analyses could not be formally evaluated because of the limited number of studies.1Miraftabi H (2026)Fast-Acting Caffeine Strategy: A Systematic Review and Meta-Analysis of the Ergogenic Effects of Caffeine Chewing Gum on Physical Performance.
Caffeine Endurance Performance Meta-AnalysisConclusion Caffeine gum produced statistically significant but trivial improvements in physical performance, suggesting limited practical significance.1Miraftabi H (2026)Fast-Acting Caffeine Strategy: A Systematic Review and Meta-Analysis of the Ergogenic Effects of Caffeine Chewing Gum on Physical Performance.
Caffeine Endurance Performance Meta-AnalysisBackground Caffeine gum is a fast-acting delivery method that rapidly elevates circulating caffeine levels and may improve physical performance.1Miraftabi H (2026)Fast-Acting Caffeine Strategy: A Systematic Review and Meta-Analysis of the Ergogenic Effects of Caffeine Chewing Gum on Physical Performance.
Caffeine Endurance Performance Meta-AnalysisGiven the recent growth in research, an updated systematic review and meta-analysis is warranted.1Miraftabi H (2026)Fast-Acting Caffeine Strategy: A Systematic Review and Meta-Analysis of the Ergogenic Effects of Caffeine Chewing Gum on Physical Performance.
Caffeine Endurance Performance Meta-AnalysisBackground and objectives Caffeine is a widely studied ergogenic aid, but evidence for its acute effects on resistance exercise performance is primarily derived from male or mixed-sex samples, with scarce data specific to women.1Liang L (2026)Acute caffeine supplementation and resistance exercise performance in female participants: a systematic review and three-level meta-analysis.
Caffeine Endurance Performance Meta-Analysis95% confidence intervals and prediction intervals were reported, and RoB 2 and GRADE were used to assess risk of bias and certainty of evidence.1Liang L (2026)Acute caffeine supplementation and resistance exercise performance in female participants: a systematic review and three-level meta-analysis.
Caffeine Endurance Performance Meta-AnalysisConclusion Acute caffeine may slightly improve maximal strength and may benefit muscular endurance in some protocols, but the certainty of evidence is low or very low for most outcomes and prediction intervals indicate limited reproducibility.1Liang L (2026)Acute caffeine supplementation and resistance exercise performance in female participants: a systematic review and three-level meta-analysis.
Caffeine Endurance Performance Meta-AnalysisPrevious women-specific syntheses did not model the multiple dependent outcomes extracted from the same crossover trial, which may have produced overly narrow uncertainty estimates.1Liang L (2026)Acute caffeine supplementation and resistance exercise performance in female participants: a systematic review and three-level meta-analysis.
