Recruitment of motor units in the medial gastrocnemius muscle during human quiet standing: is recruitment intermittent? What triggers recruitment?
The recruitment and the rate of discharge of motor units are determinants of muscle force. Within a motoneuron pool, recruitment and rate coding of individual motor units might be controlled independently, depending on the circumstances. In this study, we tested whether, during human quiet standing, the force of the medial gastrocnemius (MG) muscle is predominantly controlled by recruitment or ...

متن کاملRecruitment order of motor units in human vastus lateralis muscle is maintained during fatiguing contractions.
Motor-unit firing patterns were studied in the vastus lateralis muscle of five healthy young men [21.4 +/- 0.9 (SD) yr] during a series of isometric knee extensions performed to exhaustion. Each contraction was held at a constant torque level, set to 20% of the maximal voluntary contraction at the beginning of the experiment. Electromyographic signals, recorded via a quadrifilar fine wire elect...
متن کاملE-recruitment in Iran
Abstract In recent years, the practice of using corporate websites to recruit job applicants has increased steadily. The aim of this paper is to review and analyze the E- recruitment in Iran. in this article, we examine e-recruitment situation in premier 100 Iranian organizations through websites content analysis. These top 100 organizations were introduced by the IMI in 1390. This ranking is ...
متن کاملMotor unit recruitment and firing rate in medial gastrocnemius muscles during external perturbations in standing in humans.
There is limited investigation of the interaction between motor unit recruitment and rate coding for modulating force during standing or responding to external perturbations. Fifty-seven motor units were recorded from the medial gastrocnemius muscle with intramuscular electrodes in response to external perturbations in standing. Anteriorly directed perturbations were generated by applying loads...
