Purpose: The use of sodium bicarbonate (SB) as a preexercise ergogenic aid has been extensively studied in short-duration high-intensity exercise. Very few studies have considered the effects of SB ingestion before prolonged high-intensity exercise. The aim of the present study was to determine the effects of a 0.
View Article and Find Full Text PDFSodium bicarbonate (NaHCO) is a well-established nutritional ergogenic aid that is typically ingested as a beverage or consumed in gelatine capsules. While capsules may delay the release of NaHCO and reduce gastrointestinal (GI) side effects compared with a beverage, it is currently unclear whether the capsule size may influence acid-base responses and GI symptoms following supplementation. This study aims to determine the effects of NaHCO supplementation, administered in capsules of different sizes, on acid-base responses, GI symptoms, and palatability.

The purpose of this study was to examine the effects of enteric-coated NaHCO supplementation on high-intensity exercise performance and GI symptoms.
Methods: Eleven trained male cyclists completed three 4 km time trials after consuming; a placebo or 0.

Enteric-formulated capsules can mitigate gastrointestinal (GI) side effects following sodium bicarbonate (NaHCO3) ingestion; however, it remains unclear how encapsulation alters postingestion symptoms and acid-base balance. The current study aimed to identify the optimal ingestion form to mitigate GI distress following NaHCO3 ingestion. Trained males (n = 14) ingested 300 mg/kg body mass of NaHCO3 in gelatin (GEL), delayed-release (DEL), and enteric-coated (ENT) capsules or a placebo in a randomized cross-over design.

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.
