For high intensity exercise that lasts between 1 to 3 hours, the recommended carbohydrate intake is crucial for maintaining energy levels and optimizing performance. The correct amount is typically in the range of 6 to 10 grams of carbohydrate per kilogram of body weight per day. This level of carbohydrate intake supports the replenishment of muscle glycogen stores, which can be greatly depleted during prolonged and intense physical activity.

When engaging in high-intensity exercise for longer durations, the body relies heavily on carbohydrates as a primary fuel source. If adequate carbohydrates are not consumed, athletes may experience fatigue, decreased endurance, and impaired recovery. This recommendation of 6 to 10 grams per kilogram aligns with the needs of athletes who are training intensely, as it provides enough energy to enhance performance while also addressing recovery requirements.

Lower carbohydrate intake levels, such as those suggested in other options, would not sufficiently support the energy demands of high intensity, longer-duration exercises, potentially compromising performance and recovery.
