Abstract

Carbohydrate availability is critical for both intermittent high-intensity work and prolonged aerobic exercise.

  • Strategies promoting carbohydrate availability include ingestion before, during, and after exercise.
  • Daily carbohydrate intake guidelines have shifted from a universal recommendation to an individualized approach based on body size and exercise needs.
  • A recent concept suggests that training with low carbohydrate stores may enhance training adaptations, with subsequent restoration of carbohydrate for competition.
  • Current literature primarily focuses on low glycogen training during 'twice a day' sessions or carbohydrate withholding during workouts.
  • There is no clear evidence that training with low glycogen improves overall exercise performance.
