Carbohydrates are a crucial nutrient for energy production during exercise. They serve as the primary fuel source for the body's muscles, particularly during high-intensity activities. Upon ingestion, carbohydrates are broken down into glucose, which is utilized for immediate energy needs or stored as glycogen for future use. Adequate carbohydrate intake enhances performance, endurance, and recovery, making it essential for athletes and active individuals aiming to optimize their exercise outcomes and maintain energy levels during workouts.
