What percentage of daily energy intake may athletes require from carbohydrates?

Athletes generally have significantly higher carbohydrate needs compared to non-athletes due to the energy demands of their training and competition. Carbohydrates serve as the primary fuel for high-intensity exercise, as they can be rapidly broken down to provide energy.

For most athletes, it is recommended that carbohydrates make up a substantial portion of their total daily energy intake to optimize performance and recovery. The guideline often suggests that 60% to 70% of an athlete's total caloric intake should come from carbohydrates, especially for those involved in endurance sports or high-volume training.

Choosing the higher number, such as 70%, acknowledges the intense energy expenditure related to athletic performance, ensuring that athletes maintain adequate glycogen stores in their muscles and liver. This is crucial for sustaining long training sessions and competitions.

Therefore, option C reflects a well-supported recommendation rooted in sports nutrition principles, emphasizing the importance of carbohydrates in an athlete’s diet to meet their energy requirements effectively.
