Front

Low carbohydrate intake during prolonged exercise can lead to:

Back

Early onset of fatigue

Answer explanation

Low carbohydrate intake during prolonged exercise reduces glycogen stores, leading to early fatigue. Carbohydrates are crucial for sustained energy, and their deficiency can impair performance.
