Question

Quizplus · Accepted Answer

Slow fibers are also known as type I fibers and are characterized by their ability to sustain long, endurance-type activities. They contain a high concentration of myoglobin, a protein that binds and stores oxygen, allowing for sustained aerobic metabolism during exercise. This enables them to maintain energy production for extended periods of time without fatiguing.
