Step 1
What is the most effective source of fuel for replenishing energy stores after an athlete has completed a 800 metre track event?
Answer
To replenish energy stores after intense exercise, it is crucial to understand the metabolic demands of the body during recovery. The 800 metre track event is primarily anaerobic but also relies on aerobic metabolism to some extent.
After such exertion, the body utilizes glycogen stores for quick energy, and carbohydrate is the most efficient source to replenish these stores.
Carbohydrates are rapidly converted into glucose, which is essential for muscle recovery and restoring glycogen levels. Proteins, while valuable for muscle repair, do not replenish glycogen stores effectively. Similarly, fats and fibre are not utilized as quickly.
Hence, the correct answer is:
(D) Carbohydrate.
