These protein forms are known to produce a glucose response, likely by increasing glucagon secretion, that is relatively quick and moderately sustained (36, 37), making them a possible pre-exercise tools when exercise-induced hypoglycemia is a known threat, or in instances where continuous fueling (e.g., with glucose) during exercise is impractical, such as during competition or extended activity without breaks. This evidence concerns the gene GCG and Hypoglycemia.
