"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. " - Slow twitch muscle fibers firing rate
