Question

A marathon trainee limits quick-release fuel and relies mostly on protein. Runs feel harder. Why?
a. Protein replaces all energy needs
b.Concentrated reserves are unnecessary
c. Charged particles provide endurance energy
d. Sustained movement needs steady quick-release fuel

SnapAndSolve AI · Accepted Answer

In the context of marathon training, the body primarily utilizes carbohydrates as the main source of quick-release energy needed for endurance activities. This energy source is crucial for sustaining prolonged physical activity, especially in events like marathons that require consistent energy output over several hours.

While protein is essential for muscle repair and growth, it does not provide the immediate energy needed during endurance runs. When a marathon trainee limits quick-release fuel, such as carbohydrates, and relies mostly on protein, they are depriving their body of the necessary glycogen stores that are readily available for energy. As a result, the runs feel harder because:

The body is not getting enough quick energy to maintain the high-intensity effort required over long distances.
Fatigue will set in more quickly without sufficient carbohydrate stores, making it feel more strenuous to sustain effort.
The process of converting protein into energy is less efficient compared to using carbohydrates, leading to reduced performance and increased difficulty during runs.

The correct answer is:

d. Sustained movement needs steady quick-release fuel.
