During high-intensity exercise, fatigue refers to the abrupt deterioration of exercise performance, a gradual increase in perceived exertion which inevitably leads to an inability to maintain the intended magnitude of intensity (Ament and Verkerke et al. 2009). Performance of high-intensity exercise, which demands a large contribution from anaerobic metabolic pathways is associated with a decrease in muscle and blood pH (Hollidge-Hovart et al. In an attempt to delay the deleterious effects of fatigue on sport and exercise performance, nutritional strategies have previously been utilised. During single bouts of high-intensity exercise of ~ 1 to 10 min in duration (Gough et al. Although the extant research highlights the efficacy of SB as an effective buffering agent, a recent umbrella review of meta-analyses (Grgic et al. 2017) determined that > 77% of participants in the existing research literature were male. It is, therefore, reasonable to suggest that the generalizability of such literature is skewed, with one meta-analyses declaring it impossible to determine a precise estimate of the pooled effect size for performance (Saunders et al. This study, therefore, investigated the effect of SB ingestion on female performance in CrossFit® athletes using a time-to-peak ingestion protocol. It was hypothesised that an acute loading ingestion protocol of SB would induce metabolic alkalosis and improve 2 km time trial (TT) performance when performed at individual time-to-peak alkalosis.
