Neftaly: The Science Behind Energy Gels for Marathon Runners
Energy gels are popular among marathon runners for quick, easily digestible fuel during long-distance runs.
1. Rapid Carbohydrate Source
Energy gels provide concentrated carbs, primarily simple sugars, that quickly enter the bloodstream to maintain blood glucose levels.
2. Preventing Glycogen Depletion
By topping up energy stores mid-run, gels help delay fatigue caused by depleted muscle glycogen.
3. Easy Digestion
Formulated for quick absorption, gels minimize gastrointestinal discomfort compared to solid foods.
4. Convenient and Portable
Small, lightweight packaging makes gels easy to carry and consume on the move.
5. Electrolyte Support
Many gels include electrolytes like sodium and potassium, aiding hydration and muscle function.
