These discrepancies could be explained by various exercise protocols ( Afman et al., 2014 ), dosage ( Douroudos et al., 2006 ), gastrointestinal (GI) problems ( Burke & Pyne, 2007 ), or suboptimal timings of ingestion/individual variation in response to supplementation ( Sparks et

, carbohydrate availability indirectly influences hydration status, net protein balance, immune and gastrointestinal function, all of which have implications for recovery optimization 3 ; but in the context of gastrointestinal and immune status have generally been neglected in recovery research. 6 For example

Gastrointestinal (GI) disturbances are widely reported following sodium bicarbonate (NaHCO 3 ) supplementation ( Burke & Pyne, 2007 ; Cameron et al., 2010 ; Kahle et al., 2013 ), and although the etiology of GI disturbances involves multiple mechanisms, the neutralization of gastric acid is

Exercise-associated gastrointestinal symptoms (Ex-GIS), such as abdominal pain and nausea, have been reported in the scientific literature for almost a century ( Burgess et al., 1924 ). However, awareness of disturbances to the gastrointestinal tract, and subsequent instigation of Ex-GIS, as a

Engaging in moderate- to high-intensity exercise can increase the presence of systemic inflammatory biomarkers associated with alterations in gastrointestinal (GI) permeability. 1 Prolonged (>60 min) steady-state exercise can also increase GI permeability, even in well-trained individuals, 2 and
