Carb-rich foods play a significant role in athletic performance by providing the necessary fuel for energy expenditure. Carbohydrates are the body's preferred energy source, especially during intense exercise, where they are rapidly converted into glucose. Consuming complex carbohydrates aids in sustained energy release, supporting endurance activities. Foods like whole grains, fruits, and vegetables enhance glycogen stores, promoting optimal performance during workouts. Timing carbohydrate intake before and after exercise can enhance recovery and maximize training benefits, making them critical for athletes.
