Different carbohydrates affect exercise performance variably, depending on their types and timing. Simple carbohydrates, found in fruits and sugary snacks, provide quick energy and are ideal for immediate energy needs during high-intensity workouts. Complex carbohydrates, such as whole grains, release energy slowly, making them beneficial for endurance activities. Proper carbohydrate intake can optimize glycogen stores, enhancing overall performance and recovery. Athletes often tailor their carbohydrate consumption to suit specific workout goals, ensuring they maximize performance during exercises.
