Webb13 mars 2024 · Since fast-twitch fibers can generate more power, especially at high shortening speed ( 43 ), and as slow-twitch fibers are more fatigue resistant ( 36 ), it can be concluded that the muscle typology of an athlete is an important performance-determining factor in many sports. 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. onny thaiThe force produced by a single motor unit is determined in part by the number of muscle fibers in the unit. Another important determinant of force is the frequency with which the muscle fibers are stimulated by their innervating axon. The rate at which the nerve impulses arrive is known as the motor unit firing rate and may vary from frequencies low enough to produce a series of single twitch contractions to frequencies high enough to produce a fused tetanic contraction.
