Answer:
The correct answer is B. Endurance athletes can best delay muscle fatigue during training by eating glucose periodically during the event.
Step-by-step explanation:
Glucose is one of the most important carbohydrates and is used as an energy source by animals and plants, as it is by far the most common monosaccharide. Glucose is also a building block of starch, cellulose and glycogen polysaccharides. For this reason it is recommended that, during intense physical exercise sessions, athletes consume high-glucose food rations, so as not to deplete their carbohydrate stores and therefore continue to have available energy to carry out their routines.
