Question
What is the most important substrate for fuelling high intensity endurance exercise: a. vitamins b. fibre c. protein d. carbohydrates
Solution
The most important substrate for fuelling high intensity endurance exercise is d. carbohydrates.
Here's why:
-
During high intensity exercise, your body primarily uses glycogen, which is the stored form of carbohydrates in your muscles and liver.
-
Carbohydrates can be quickly broken down into glucose, which is then used to produce ATP (adenosine triphosphate). ATP is the primary energy carrier in all living organisms and necessary for muscle contraction.
-
While protein and fat can also be used to produce energy, the process is slower and less efficient. Therefore, they are primarily used during lower intensity
