Twitch contraction phases
WebCalcium ions are binding to troponin during the _____ of a muscle twitch. 1.Contraction phase, 2.Latent period, 3.Latent period and the contraction phase, 4.Recovery phase, … WebThe hyperpolarization phase of a skeletal muscle twitch is when the muscle cell is in its most negative state. This phase occurs after the action potential has passed and the muscle cell is no longer contracting. The other three phases of a skeletal muscle twitch are the latent period, the contraction phase, and the relaxation phase.

The presence of an LTR indicates the likelihood of a MTrP in the examined muscle. LTR is a rapid reflexive contraction of the muscle fibers in a taut band associated with a MTrP as the therapist's fingers snap perpendicularly across the taut band.
