A Novel Ingestion Strategy for Sodium Bicarbonate Supplementation in a Delayed-Release Form: a Randomised Crossover Study in Trained Males.

Background: Sodium bicarbonate (NaHCO) is a well-established nutritional ergogenic aid, though gastrointestinal (GI) distress is a common side-effect. Delayed-release NaHCO may alleviate GI symptoms and enhance bicarbonate bioavailability following oral ingestion, although this has yet to be confirmed.

Methods: In a randomised crossover design, pharmacokinetic responses and acid-base status were compared following two forms of NaHCO, as were GI symptoms.

The Reproducibility of 4-km Time Trial (TT) Performance Following Individualised Sodium Bicarbonate Supplementation: a Randomised Controlled Trial in Trained Cyclists.

Background: Individual time to peak blood bicarbonate (HCO) has demonstrated good to excellent reproducibility following ingestion of both 0.2 g kg body mass (BM) and 0.3 g kg BM sodium bicarbonate (NaHCO), but the consistency of the time trial (TT) performance response using such an individualised NaHCO ingestion strategy remains unknown.
