Actually, it's the opposite. Low-twitch muscle fibers, also known as Type I fibers, are characterized by a high resistance to fatigue. These fibers are more efficient at using oxygen to generate energy through aerobic metabolism. They are well-suited for endurance activities, such as long-distance running or cycling.
In contrast, high-twitch muscle fibers, or Type II fibers, are more prone to fatigue quickly but generate more force and power. These fibers are engaged during activities that require short bursts of intense effort, such as sprinting or weightlifting.
So, low-twitch muscle fibers are associated with endurance and have a high resistance to fatigue, making them suitable for prolonged, sustained activities.
