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.

- Sodium bicarbonate (SB) has been primarily studied for its effects on short-duration high-intensity exercise, but this study aims to explore its impact before prolonged high-intensity activities, specifically a 16.1-km cycling time trial.
- Ten trained male cyclists participated in a randomized crossover design, where they ingested SB in two forms (gelatin and enteric capsules) and a placebo, assessing their performance in the cycling trials.
- Results showed significant improvements in performance times with SB ingestion compared to placebo, particularly with enteric capsules having fewer gastrointestinal issues, suggesting SB can enhance endurance cycling performance.
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.
