contraction,

in physics: see expansionexpansion,
in physics, increase in volume resulting from an increase in temperature. Contraction is the reverse process. When heat is applied to a body, the rate of vibration and the distances between the molecules composing it are increased and, hence, the space occupied by the

The muscle was stimulated at 100 Hz to cause tetanic contraction. During tetanic contraction via a skin electrode, ECs were performed 10 times as a single bout with simultaneous forced dorsiflexion of the ankle joint (velocity, 15[degrees]/s; range of motion, from 0[degrees] to 45[degrees]).
The symptoms includes cramps, tingling sensation, paresthesia, tetanic contractions, seizures, muscle spasms, and prolong QT interval prolongation on electrocardiogram.7 The most common cause of postthyroidectomy is injury to parathyroid gland.
More tetanic contractions are required for activating glucose transport maximally in trained muscle.
