How many grams of carbohydrates per kilogram of body weight are recommended for athletes?

1. 3-5 g/kg BW

2. 6-10 g/kg BW

3. 1-3 g/kg BW

4. 5-7 g/kg BW

The correct answer is: 6-10 g/kg BW

For athletes, a carbohydrate intake of 6-10 grams per kilogram of body weight is generally recommended to support optimal performance, especially in high-intensity training or endurance events. This range is aimed at ensuring that athletes have sufficient glycogen stores, which are crucial for energy during prolonged or strenuous physical activities. Carbohydrates serve as the primary fuel source for the body, particularly during exercise, and adequate intake helps not only in maximizing energy levels but also in recovery post-exercise. The need for higher carbohydrate intake is driven by the increased demands placed on the body during training and competition, as well as the metabolic adaptations that occur. Proper carbohydrate consumption can help prevent fatigue, sustain performance, and allow for quicker recovery times, which are vital for athletes who need to train frequently. Other ranges that were provided, such as 3-5 g/kg, 1-3 g/kg, and 5-7 g/kg, are generally insufficient for athletes engaged in rigorous training or competition, as they do not meet the energy needs required to support prolonged efforts in their sport. Thus, the recommendation of 6-10 g/kg is tailored to meet the unique demands of athletes’ training regimens.
