Slow twitch muscle fibers firing rate

WebbIt follows that anconeus can be classified as a slow muscle, as opposed to the lateral head of triceps. The relationship between MU firing rate and isometric force, tested at 90 … 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.

Webb22 maj 2014 · Studies of single fast and slow fibres, and whole muscles containing predominantly fast or slow motor units, show that isometric force rise time is shorter [ 12, 20, 21 ], maximum shortening velocity higher and the curvature of the force–velocity relationship lower in faster fibres [ 12, 17, 18, 20 ]. 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.
