What role do carbohydrates play in sports nutrition, and should athletes follow low-carb diets?

Carbohydrates play a crucial role in sports nutrition as they are the primary and preferred source of energy for the body, particularly during high-intensity exercise. Carbohydrates are stored in the muscles and liver as glycogen, and during physical activity, these glycogen stores are tapped into to provide the necessary fuel. Here are key aspects of the role of carbohydrates in sports nutrition:

1. Energy Source:

• High-Intensity Activities: Carbohydrates are the most efficient fuel for high-intensity and anaerobic activities, such as sprinting and weightlifting.

• Endurance Activities: For prolonged, aerobic activities like distance running or cycling, carbohydrates remain a crucial energy source.

2. Glycogen Stores:

• Depletion during Exercise: Prolonged exercise can lead to the depletion of glycogen stores.

• Fatigue Prevention: Maintaining adequate glycogen levels helps prevent premature fatigue during prolonged activities.

3. Recovery:

• Glycogen Replenishment: Consuming carbohydrates post-exercise is crucial for replenishing glycogen stores and supporting muscle recovery.
