WebbReportedly the speed of muscle fiber contraction is directly proportional to relative myosin ATPase activity (at pH 9.4) while fatigability relates to relative oxidative capacity. Type I fibers have low ATPase activity (at pH 9.4), are slow twitch, have high oxidative and low glycolytic capacity, and are relatively resistant to fatigue. Webb10 sep. 2024 · Type I, or slow-twitch fibers, are seen in high abundance in elite endurance athletes, such as long-distance runners and cyclists.

WebbFor smaller loads requiring less force, slow twitch, low-force, fatigue-resistant muscle fibers are activated prior to the recruitment of the fast twitch, high-force, less fatigue-resistant muscle fibers. Larger motor units are typically composed of faster muscle fibers that generate higher forces. [4] WebbSlow Twitch Muscle Fibers (Type 1) These fibers specialize in low-intensity sustained activity, such as riding at an easy endurance pace. They contain lots of mitochondria, which they use to efficiently fuel themselves through aerobic metabolism. If properly fueled they can sustain almost indefinitely, but they can not exert high force.
