What is the consequence of insufficient carbohydrate intake for athletes?

Insufficient carbohydrate intake in athletes leads to decreased glycogen stores and negatively impacts performance. Glycogen, which is stored in muscles and the liver, serves as a primary fuel source during high-intensity exercise. When carbohydrate intake is inadequate, the body relies more heavily on alternative energy sources, such as fats and protein, which are less efficient for fueling intense and prolonged physical activity.

Low glycogen levels can result in early onset of fatigue, decreased endurance, and impaired performance during training or competition. This is particularly critical for athletes participating in endurance sports, where glycogen depletion can significantly hinder their ability to maintain optimal performance levels. Therefore, adequate carbohydrate intake is essential for sustaining energy, enhancing performance, and ensuring readiness for subsequent workouts or competitions.
