Sentence examples for motor unit change from inspiring English sources

When a muscle changes its length, the shape and amplitude of the motor unit change progressively [14, 35].

Repeated contractions led to earlier motor unit changes and fatigue.

Objective: To examine motor unit changes during the development of fatigue in healthy subjects.

Therefore, despite the absence of significant differences in EDL muscle force characteristics and since motor unit changes are not always immediately reflected in alterations in muscle phenotype, we assessed the number of functional motor units that innervated EDL muscles of mice of each genotype.

Motor unit potential changes and maximal recruitment pattern were evaluated with a semiquantitative recording.

Four years earlier at the age of 55, ENMG measured in another laboratory revealed only slight signs of unspecific neuropathy as increased latencies and diminished persistencies of the lower extremity F- and H-waves as well as slight fibrillation and MUP (motor unit potential) changes in the distal leg muscles.

Presumably, as more motor units are recruited with higher levels of force generation, the type of motor unit will gradually change from the less fatigable type I units to the larger type IIa and IIb units that are capable of generating more force.

These adaptations occur as a result of alterations in hormone levels, neuromuscular junction activity, motor unit recruitment, and changes in the contractile proteins in muscle [ 6– 8].

Numerous studies have investigated changes in motor unit firing rates after resistance training and have shown that the change in motor unit firing rate is dependent on the type of muscle contraction.

Electromyographic patterns of the knee suggest changes in motor unit function associated with early OA and the magnitude of this change was higher in more severe cases [ 3].

Age-associated changes in motor unit physiology: observations from the Baltimore Longitudinal Study of Aging.
