Glucose–fructose ingestion and exercise performance: The gastrointestinal tract and beyond
How Eating Glucose and Fructose Affects Exercise Performance Through Digestion and Other Body Systems
AI simplified
Abstract
Ingestion of glucose and fructose (GLUFRU) may enhance endurance exercise performance compared to glucose alone.
- GLUFRU ingestion may improve intestinal carbohydrate absorption and limit discomfort during exercise.
- Fructose is metabolized differently than glucose, primarily being converted to glucose and lactate in the liver.
- Increased circulating glucose and lactate from GLUFRU could influence muscle metabolism and enhance performance.
- GLUFRU may also produce non-metabolic effects that are currently not well understood.
- Future research could explore the effects of GLUFRU across various exercise types and athletic groups.
