Endurance Athlete Fueling

Meaning

Endurance Athlete Fueling refers to the specialized, periodized nutritional strategy designed to meet the extreme energy demands of prolonged, continuous physical activity, often lasting several hours or days. This regimen prioritizes maximizing endogenous fuel stores, specifically muscle and liver glycogen, while simultaneously ensuring adequate intake of fluid and electrolytes to maintain osmotic balance and prevent fatigue. Proper fueling is critical for sustaining performance, mitigating muscle catabolism, and supporting the hormonal adaptations required for chronic endurance training.
