How Eating Carbohydrates During and After Intense Exercise Helps Improve Sports Performance

AI simplified

Abstract

Athletes are advised to ingest 30-60 g of carbohydrates per hour during exercise lasting 1 to 2.5 hours.

  • Endogenous carbohydrate availability is insufficient for sustained moderate to high-intensity exercise.
  • Carbohydrate ingestion during high-intensity exercise may enhance performance.
  • Well-trained endurance athletes can metabolize up to 90 g of carbohydrates per hour when consuming a mixture of glucose and fructose.
  • Carbohydrate intake timing may vary based on the type of sport for intermittent or team athletes.
  • To recover for peak performance within 24 hours after intense exercise, a rapid carbohydrate supplementation strategy is recommended.
