topicElectrolyte Sodium Endurance Performance Trial
claimSodium bicarbonate (SB) ingestion may improve high-intensity exercise performance in efforts that range from 1 to 60 min; however, to date, no studies have investigated the effects of SB supplementation during exercise, nor its potential to attenuate the fatigue-induced decline in parameters of the power-duration curve during prolonged exercise (i.e., durability).
