Impact of Different Carbohydrate Feedings on a Hydrogen Breath Curve and Self-reported Gastrointestinal Complaints

Description

GI distress is widely prevalent among athletes, ranging from 30 to 90% in recreationally and professionally active athletes. As the recipient of nutrients, the gastrointestinal (GI) tract plays an important role in athleticism. The following pilot project aims to better understand if a fructose load after hiking under heat stress will result in a meaningful hydrogen breath elevation as a marker for malabsorption in healthy participants, and if supplementation of a multi-ingredient fermented whey supplement will result in a different hydrogen breath response rate after a heat stress hiking test.
