This question asks about the appropriate target daily carbohydrate intake for an athlete engaged in high-intensity, short-duration exercise (1–30 minutes) with adequate energy intake.
Option 1: 5-7 g/kg. This range aligns with common sport-nutrition guidelines for athletes participating in high-intensity activities, providing enough carbohydrate to sustain performance and replenish glycogen without overconsuming. It strikes a balance suitable for shorter, intense efforts where maximal glycogen stores are helpful but total daily intake should remain practical.
Option 2: 8-12 g/kg. While this range is appropriate for athletes with very high daily training volume or endurance events lasting many hours, it tends to exceed the needs for a shorter high-intensity protocol if energy intake is already adequate. It risks unnecessary total carbohydrate intake and potential fat gain if calories are not being expended at that level.
Option 3: 5-10 g/kg. This range includes the correct 5-7 g/kg window but spreads upward a bit wider, which reduces precision. For athletes focusing specifically on high-intensity, short-duration exercise, sticking to the lower end (5-7 g/kg) is typically preferred to ensure adequate glycogen without overdoing total carbohydrate intake.
Option 4: 6-8 g/kg. This is a narrow range that lies between 6 and 8 g/kg; while it overlaps with the correct zone, it fails to capture the commonly recommended 5-7 g/kg target as the standard for many high-intensity scenarios. It may be acceptable for some athletes, but it's not the textbook match for this exact scenario.
