Sodium bicarbonate ingestion and repeated sprint performance: a meta-analysis
Christensen PM, Shirai Y, Ritz C, Nordsborg NB
Published in Frontiers in Physiology
Methodology
Meta-analysis of randomized crossover trials of sodium bicarbonate before repeated high-intensity exercise, with blood lactate and pH as mechanistic outcomes.
Key Findings
Bicarbonate raised extracellular buffering capacity and blood lactate efflux, with small but consistent improvements in repeated sprint performance.
Conclusions
Sodium bicarbonate accelerates lactate and hydrogen ion clearance from working muscle, modestly improving repeated high-intensity work.
Limitations
Heterogeneous protocols and doses; gastrointestinal side effects common and may unblind participants.
Outcomes Measured
Bicarbonate raised extracellular buffering capacity and blood lactate efflux, with small but consistent improvements in repeated sprint performance
