What role do carbohydrates play in physical performance?

Carbohydrates are crucial for physical performance, especially during high-intensity exercise. During activities that demand a significant amount of energy, such as sprinting, weightlifting, or any form of vigorous aerobic exercise, the body relies heavily on carbohydrates as a primary fuel source. This occurs because carbohydrates are converted into glucose, which is then utilized by the muscles for immediate energy.

When engaging in high-intensity exercise, the body's demand for energy increases rapidly, and carbohydrates can be metabolized quickly to meet that demand. This makes them more efficient than fats or proteins for supporting short bursts of exertion. Additionally, having adequate carbohydrate stores can enhance performance, delay fatigue, and improve recovery during subsequent workouts or competitions.

While carbohydrates do play a role in low-intensity exercise and are involved in muscle repair, their most significant impact is observed during high-intensity activities where quick energy release is essential.
