Introduction
High-intensity functional training (HIFT) is derived from (1) well-studied high-intensity interval training (HIIT), in which relatively short bouts of high-intensity exercise separated by a recovery using low-intensity or inactivity are used as an alternative to traditional aerobic training to promote metabolic conditioningThe majority of studies focusing on HIFT methodology have used a cross-training templateDespite the growing popularity of HIFT and CrossFit training, limited interventional data exist on dietary and supplementation strategies to enhance performance in CrossFitNumerous different protocols of SB supplementation have been investigated, however, so far only two protocols have been implemented in CrossFit-trained athletesAlthough the performance benefits with SB are well documented, data linking the kinetics of blood HCO
