Which skeletal muscle fiber type is characterized by high resistance to fatigue,slow twitch,high aerobic capacity,and high myoglobin content?

Question

Quizplus · Accepted Answer

Type I skeletal muscle fibers, also known as slow-twitch fibers, have a high resistance to fatigue, a slow contraction speed, high aerobic capacity, and high myoglobin content. Myoglobin is a protein that stores oxygen, allowing for sustained aerobic metabolism. Type IIA and IIX (IIB) fibers are fast-twitch fibers and have lower aerobic capacity and fatigue resistance, while Type X fibers do not exist in humans.
