The Magnitude of the Blood Acid-Base Response, but Not Time to Peak, Is Reliable Following the Ingestion of Acute, Individualized Sodium Citrate.

Enhanced buffering capacity following sodium citrate (SC) ingestion may be optimized when subsequent exercise commences at individual time-to-peak (TTP) alkalosis (blood pH or bicarbonate concentration [HCO3-]). While accounting for considerable interindividual variation in TTP (188-300 min), a reliable blood alkalotic response is required for practical use. This study evaluated the reliability of blood pH, HCO3-, and sodium (Na+) following acute SC ingestion.

A virtual versus blended learning approach to higher education during the COVID-19 pandemic: The experiences of a sport and exercise science student cohort.

During the 2020/21 academic year most UK universities rapidly developed learning material as part of a move to blended learning, in response to the COVID-19 pandemic. This was interspersed with periods of virtual-only delivery, aligning with national lockdowns. The previous literature suggests there are both advantages and disadvantages to virtual-only and blended learning approaches, which may impact on student satisfaction.

Capsule Size Alters the Timing of Metabolic Alkalosis Following Sodium Bicarbonate Supplementation.

Sodium 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.
