Question

Quizplus · Accepted Answer

Fast glycolytic fibers are primarily used for rapid, powerful contractions and contain the most glycogen granules of all muscle fiber types. These fibers rely heavily on anaerobic glycolysis for energy, which requires a ready supply of glycogen. Slow oxidative and fast oxidative fibers have fewer glycogen granules as they rely more on aerobic metabolism and fatty acid oxidation, respectively. Slow glycolytic fibers are intermediate in terms of glycogen content.
