Question

Quizplus · Accepted Answer

Slow fibers, also known as type I fibers or red fibers, are best adapted for prolonged contraction. They have a high oxidative capacity and are fatigue-resistant, making them well-suited for endurance activities such as standing all day. In contrast, fast fibers (types IIa and IIb) have low oxidative capacity and fatigue quickly, making them better suited for explosive activities such as sprinting. Uninucleated, striated, and intermediate fibers do not affect muscle endurance directly.
