Abstract
Exercise performed under heat stress conditions is associated with an increase in gut permeability, commonly known as "leaky gut.". Recent studies suggest that sodium bicarbonate ingestion (NaHCO3) before exercise in the heat may offer ergogenic benefits. However, NaHCO3 is known to induce gastrointestinal discomfort (GI) and potentially exacerbate gut permeability. Therefore, this study investigated the effects of NaHCO3 on markers of gut permeability and gastrointestinal discomfort after prolonged physical exercise in a hot environment. To test this, we analyzed markers of intestinal permeability and injury pre and post exercise under heat stress comparing a NaHCO3 group to a placebo group. GI assessment was conducted pre- and post NaHCO3 ingestion or placebo, 1-hr within the exercise and post exercise. Additionally, physiological variables such as core temperature (Tc) and heart rate (HR) and rating of perceived effort (RPE), were also recorded during exercise.
