The type of carbohydrate consumed significantly affects energy levels during workouts. Simple carbohydrates, such as sugars, provide quick energy, beneficial for high-intensity activities. In contrast, complex carbohydrates, found in foods like whole grains and legumes, offer sustained energy during longer workouts by releasing glucose gradually. Choosing the right type of carbohydrate can enhance performance and endurance, significantly impacting overall training effectiveness. A balanced intake of both types, depending on exercise demands, is essential for optimal energy management.
