Question: 1 / 400

What does glycogen sparing refer to during endurance exercise?

The exclusive use of carbohydrates for energy

The metabolism of fat instead of carbohydrates during endurance work

Glycogen sparing specifically refers to the body's ability to utilize fat as a primary energy source during endurance exercise, thereby conserving glycogen stores for later use. During prolonged physical activity, when glycogen (the stored form of carbohydrates) levels are limited, the body becomes more efficient at metabolizing fat, which is a more abundant energy source. This adaptation is significant for endurance athletes as it allows them to delay fatigue and maintain performance for a longer duration by preserving glycogen for critical moments when it is most needed.

In contrast, emphasizing an exclusive use of carbohydrates would not align with the concept of glycogen sparing, as that would imply depleting glycogen without taking advantage of fat metabolism. Reducing glycogen consumption does not fully convey the physiological adaptation of using fat for energy, and the process of storing excess carbohydrates as glycogen does not relate to energy usage during exercise.
