Their novel approach uses large scale ... WebbThe 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. Generally, this allows a 2 to 4-fold change in force.

Webb6 apr. 2024 · Fast-twitch, type II muscle fibers are further divided into type IIa and type IIb. Whereby type IIb (Fast-twitch glycolytic) fibers are more powerful but less resistant to fatigue than type IIa (Fast-twitch oxidative) fibers. For an image of muscle fibers from following paper: Muscle fiber type diversity revealed by anti‐myosin heavy chain ... 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. The 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.
